Mitigating climate change through healthy discomfort
Authors: Koth S C , Kobas B , Bausch K , Auer T
Published: September 2022

Amid the climate change and the worldwide catastrophes, witnessed on a daily, we find ourselves in a time in which we need to start justifying any recourse and energy consumption, at least of which is not truly renewable. While the outside temperatures become more extreme, the inside environment becomes more relevant. The way we design and operate our buildings is directly influenced by current building standards and as we spend almost all our time indoors, our comfort, wellbeing and health are crucially affected by such. The last five decades have seen many approaches in establishing guidelines for a comfortable indoor environment. But while current standards favor the narrow temperature ranges of static homogeneous environments, they have been criticized for their high energy consumption and long-term health implications. The paper compares a typical office space with mechanical cooling with that of a passive strategy, by evaluating the energy consumption and health over comfort. The results show a 64% cooling potential within the mechanically cooled scenario as well as the passive strategy complying to standard without any cooling energy.
Net zero emission buildings: next generation of benchmarks and calculation rules
Authors: Balouktsi M , Lützkendorf T
Published: September 2022

The definition of ambitious life cycle-based benchmarks and target values to limit the GHG emissions of buildings is seen as one of the most important steps in pushing the construction and real estate sector in significantly reducing its contribution to global warming. Especially target values are no longer only developed from a bottom-up perspective. There is now an interest by governments and sustainability assessment system providers in supplementing bottom-up approaches with science-based top-down approaches as part of their responsibility to respect planetary boundaries. The creation of GHG emission budgets in combination with target values, as well as the introduction of strict enough legal binding requirements already today is critical for achieving a climate-neutral building stock. Achieving these tasks requires tackling still open methodological issues. Following the work of IEA EBC Annex 72 and current developments in Germany, the paper presents main questions, key steps, modelling aspects that can cause variation and uncertainties, as well as clarifies key terms and definitions. It is highlighted that although a net zero emission requirement is a universal benchmark, information on system boundaries and calculation rules are still necessary to provide evidence of its fulfilment.

Authors: Wagner A , Hebel D , Carbonare N , Gebauer Regina
Published: September 2022

The contribution of the RoofKIT team to the SDE 21/22 competition is the extension for an existing café in Wuppertal, Germany, to create new functions and living space for the building with simultaneous energetic upgrading. The energy concept targets all renewable resources available on and in the building for energy supply: mainly solar energy which is used via PVT collectors, as well as waste heat from ventilation and grey water which is recovered for pre-heating. As part of the competition, a demonstration unit will be built representing a small cut-out of the extension. An integral building and energy concept combines physical properties of the building with adapted building services technologies to achieve maximum indoor comfort – particularly considering possible overheating of the lightweight construction during summer – and minimum CO2 emissions. The latter extends to the whole lifecycle of the building unit and one of the major goals of the project is to realize an almost completely mono-fraction and circular building construction as a contribution to the urban mining concept.
Unboxing Urban Infrastructure: Three Methodologies for infrastructure-oriented Urban Design and Architecture Education
Authors: Bauer D
Published: September 2022

Although the exploration of infrastructure has become a main focus of urban-centered studies and urban theory over the last decade, it has only been partially adopted into design and planning education. Here, the traditional curriculum of architecture, urban planning, landscape architecture, and urban design offers emerging professionals limited guidance and tools for exploring and analyzing the complex assemblages and constituting systems that create, run, and shape cities. However, in times of dramatic need for systemic transformation, the critical and research-based analysis of the city’s externalities and the flows underlying urban life will become more relevant by the day. Thus, the following article outlines three teaching methodologies for analyzing “infrastructural regimes” as key levers and contexts to embed a reflected and responsive design work directed at transformation towards global sustainability.

Authors: Trummer J , Schneider M , Lechner M , Jarmer T , Demoulin T , Landrou G , Nagler F , Winter S , Dörfler K
Published: September 2022

The production of floor slabs with their high requirements for fire protection, thermal mass, and sound insulation is a central challenge in multi-storey timber construction. The research presented in this paper explores the possibilities of a timber-earth slab (T.E.S.) that can meet such high demands while being fully recyclable. T.E.S. comprises a hybrid structure, which aims to combine the strong tensile properties of wood with the beneficial properties of earth in terms of thermal mass, thermal activation capabilities, fire resistance, and sound insulation. It integrates a novel material technology capable of casting earth with low water content and combines it with robotic technology that enables the bespoke fabrication of a filigree wooden structure tailored to mechanically interlock with the earth infill. The proposed method makes it possible to place the earth infill in the lower part of the floor slab and thus expose it to the interior space, whereby its storage mass and component activation can be fully utilized. This paper presents the concept and design principles, initial findings on the system’s loadbearing behaviour, as well as the experimental validation of the novel fabrication process in 1:4 and 1:1-scale demonstrators, in which the general feasibility of the system in assessed. The paper finally discusses the proposed methods and results of the experiments and outlines further steps for transferring the system into building practice.

Published: September 2022

Reducing the embodied emissions of materials for new construction and renovation of buildings is a key challenge for climate change mitigation around the world. However, as simply reducing emissions is not sufficient to meet the climate targets, using bio-based materials seems the only feasible choice as it permits carbon storage in buildings. Various studies have shown that bio-based materials allow turning overall life cycle impacts negative, therefore, having a cooling effect on the climate. In recent years, scholars and policy makers have focused almost exclusively on the advancement of wooden buildings. Timber structures stand out as they can be prefabricated and used for high-rise buildings. Yet, one important aspect seems to be overlooked: the consideration of supply and demand. Large forest areas that allow sustainable sourcing of woody biomass only exist in the Northern hemisphere, notably in North America and Europe. In these regions, though, urbanization rates are mostly stagnating, meaning new construction rates are low. The largest amount of material requirements in these regions are derived from the refurbishment of the existing stock. Moreover, in areas where structural material is needed for new construction, in Asia, Africa and South America, rain forests need to be protected. Therefore, we need to rethink the desire to find one solution and carelessly implement it everywhere. Instead, we need to consider locally available material and know-how for grounded material choices. This paper explores the supply of a range of bio-based materials and matches it against the material demand of global building stocks. It is based on various previous studies by the authors, of South Africa, China, Portugal, and more. The analysis divides between structural materials for new construction, such as wood and bamboo, and thermal insulation materials for the refurbishment of existing buildings, such as straw and hemp. The results emphasize the need for diversifying bio-based material solutions.
The voices of vulnerable tenants in renovation
Authors: Femenias P , Punzi E , Granath K
Published: September 2022

This paper focuses on the intersection between agendas for housing renovation and social politics for ageing-in-place and social integration of people with psycologial disabilities. The aim is to understand how elderly tenants and people on a longer sick leave are affected by a renovation. In a sample of 79 interviews, 34 tenants decided to permanently relocate as a results of a renovation. When the renovation is a driver for permanent relocation, tenants do so to avoid disturbances and temporal evacuation. If the home is subjet to a comprehensive or deep renovation, rent increases is another reinforcing factor to relocate. While tenants that move prior to a renovation worry about how the renovation will affect their daily life and their economy, tenants that move after the renovation do so because they are dissatisfied with the results of the renovation. The findings calls for awareness for how housing renovation will affect vulnerable tenants and highlights the need for the design or appropriate communication strategies.
Tool characterisation framework for parametric building LCA
Authors: Säwén T , Magnusson E , Sasic Kalagasidis A , Hollberg Alexander
Published: September 2022

Connecting Life Cycle Assessment (LCA) to parametric design has been suggested as a way of facilitating performing environmental assessments in early design stages. However, no overviews of potential approaches and tools are available within recent research. Also, no characterisation frameworks adapted for parametric LCA tools are present. In order to guide the development of workflows for environmental analysis aimed at the early design stage of buildings, the goal of this paper is to provide such a framework, and to demonstrate its use by characterising a number of available LCA plug-ins for the commonly used parametric design framework Grasshopper® (GH). First, a framework for classification and characterisation of tools based on workflow, adaptability, and required user knowledge was developed. Second, a tool inventory was performed, identifying 13 parametric LCA plug-ins for GH. Finally, four of these plug-ins were further investigated using the developed evaluation framework, a user persona approach, and a simplified test case. It was found that the characterisation framework was able to differentiate tools based on the level of LCA expertise integrated in the tools, and the allocation of responsibility for data entry and interpretation. A contrast was found between streamlined tools, and tools which provide more versatility. The characterisation framework, and the resulting overview of approaches can be used to guide the future development of parametric environmental analysis frameworks.

In a context of digitalization and increasing quality requirements, the building sector is facing an increasing level of complexity regarding its design process. This results in a growing number of involved actors from different domains, a multitude of tasks to be completed and a higher degree of needed expertise. New buildings are also required to reach higher performances in terms of environmental quality. To that regard, the exploitation of the full potential of digital tools can facilitate the integration of environmental aspects in the planning process, limit productivity shortcomings and reduce environmental impacts, which can result from an unaware decision making. Building environmental assessment can be performed through several Life Cycle Assessment (LCA)-based tools. “Pure calculation” tools quantify final buildings’ environmental potential, while “complex tools” additionally support decision making during the planning process. It is often difficult to choose the best suitable tool, which strongly depends on the user’s needs. Within the IEA EBC Annex 72, a survey was realized with the main objective of creating a comprehensive overview of the existing tools dedicated to buildings LCA. The questionnaire included the usability, functionality, compliance, data reliability and interoperability of the analysed tools. Lastly, based on the survey outcomes and their critical assessment, a procedure for the identification and selection of a tool has been proposed based on user’s needs. As a result, this work outlines main features of currently available building LCA tools, for which there is a harmonized status in terms of usability and overall applied LCA methodology. Despite the need for more automatized workflows, tools’ embedding is mostly not yet applicable in system chains or limited to a restricted number of tools.
What is the impact of a basement on a building LCA and what role does the functional unit play?
Authors: Hartmann C , Özdemir Ö , Hafner A
Published: September 2022

The goal of reaching nearly zero emissions in the construction sector by 2045 is important and at the same time ambitious. Therefore, emissions from operation and structural design of a building play an important role. Life cycle assessment is an established method for determining the environmental impact of a building throughout its life cycle. The implementation of an LCA follows in general the standards ISO 14040 / 14044, and on building level the standard EN 15978. It requires, among other things, the definition of the goal, the system boundaries and the functional unit. For buildings with basements, there are certain discrepancies in the definitions of goals, system boundaries, and functional units. When the production, construction and maintenance phases of a building are included in the system boundaries of the LCA, the whole building is considered and is for example related to the functional unit gross external area or others as net external area or heated area. The set goal, system boundaries and selection of the functional unit has a direct influence to the LCA results. In this paper, the effects of a basement on the LCA results of the operational and structural design of a building are presented as a function of different functional units. Therefore, a comparative LCA on residential buildings in two different energy standards (level 40, level 55) and additionally for conventional and future-oriented construction were calculated.
A carbon-focus parametric study on building insulation materials and thicknesses for different heating systems: A Swiss case study
Authors: Neves Mosquini L H , Tappy V , Jusselme T
Published: September 2022

To tackle the problem of climate change, Swiss energy strategies aim to reach the carbon neutrality by 2050. However, this challenge cannot simply be solved by focusing on the operational energy performance and instead, on a lifecycle evaluation. Thus, in order to reduce the sector’s carbon footprint, building stakeholders need to consider embodied GHG emissions of construction materials. In this study, a parametric method was developed to balance operational and embodied impacts of insulation strategies on GHG emissions according to the material and heating system choices. The methodology is split into two for the computation of the overall carbon emissions of the heating plus insulation system. Firstly, the calculation of the embodied emissions, which relies on Environmental Product Declarations of different construction materials. Secondly, the calculation of the operational emissions, which is the product between the thermal energy needs and the energy carbon content of the respective heating system. Thereafter, the methodology was applied to two case studies: an existing building and a brand-new building. The first main finding was that, for high-carbon insulation materials, there was clearly an optimal thickness after which, adding insulation would only increase the lifecycle impact of the system. For instance, in the heat-pump equipped case study, installing 35 cm of extruded polystyrene insulation (XPS) is more harmful towards global warming than installing 17 cm of XPS. This trend was not present for low-carbon materials whatsoever. The building’s carbon emissions benefitted from their addition of insulation up to the maximum thicknesses studied. To conclude, it is also important to highlight that aimlessly targeting energy efficiency can be a step back towards the goal of carbon neutrality. Indeed, it is possible to claim that for energy efficient buildings, fossil fuel-based insulation should be carefully used. This study allowed the development and application of a method that identifies optimal insulation thickness and material for a given heating system and hopefully, highlight the importance of considering both embodied and operational emissions of construction materials and systems.
Development of an advanced methodology for assessing the environmental impacts of refurbishments
Authors: Obrecht T P , Jordan S , Legat A , Saade M R M , Passer A
Published: September 2022

The refurbishment of the building stock is one of the key tasks for reducing the future environmental emissions in building sector. The assessment of the environmental impacts (EI) of refurbishments with LCA methodology remains a challenge. In the current practice, the refurbishment is threated as the beginning of the new lifecycle and all the impacts associated with the previous life cycle are generally neglected. The exclusion of materials and components used prior to the refurbishment produces a data gap at the end-of-life since information about materials that remained in the building after the refurbishment are missing. Furthermore, no information about what impacts have already been considered in the past bears the risk that some of the impacts are double-counted. In order to overcome these problems, an advanced methodology for the assessment of the embodied impacts in the case of refurbishment was developed that combines two sub-methodologies that can also be used separately. The first sub-methodology is used for remodelling the input data in order to make them time corresponding. The second sub-methodology is used for the assessment of the EI in the residual value of building materials and components and is including the allocation of EI between the life cycle before and after the refurbishment. The combination of the two sub-methodologies enables a more realistic and accurate assessment of the environmental impacts. The methodology is illustrated on the case on the case of a façade refurbishment. Five different allocation approaches are investigated and the residual value is calculated after a selected time period before and after the refurbishment. For all the inputs time-corresponding data is modelled and used. The study showed that for the life cycle before the refurbishment the EI and the residual value are generally higher if time-corresponding data is used since the EI of the electricity mix are higher. It turned out that the use of different allocation approaches is favouring either the use of recycled or reused materials or the recycling of the materials at the end. The PEF and the cut-off approach with module D are both enhancing the circular economy. It can be assumed that they are likely to prevail in the future.
Management and communication of HVAC-specific life cycle-related information - filling the gaps for sustainability assessment of buildings
Authors: Rochlitzer D , Lützkendorf T
Published: September 2022

Assessing the contribution of buildings to sustainable development is no longer just a matter of scientific investigation. Increasingly, such considerations are becoming a prerequisite for the award of subsidies or the fulfillment of legal requirements. One aspect is the evaluation of the environmental performance, based on a life cycle assessment of the complete building in its life cycle. This requires corresponding data on all installed products (materials, components, systems) on a consistent methodological basis and suitable communication forms. To that, information is required on technical characteristics and the life cycle assessment results of construction products. Thereby the following problems are occurring: (1) there are not enough environmental product declarations according to EN 15804 A2 available in the field of building services systems (e.g. HVAC) and (2) the data contained in EPDs do not fully cover the information needs of designers and decision-makers. This complicates the work of involved actors and endangers the competitiveness of product suppliers. In response, a proposal for a product information system for building services is presented. It is adapted to the specifics of HVAC systems and the information needs of related actors. The background is the situation in Germany, but results can be transferred to other countries / markets.
Social innovations for supporting regenerative lifestyles: exploration of three pioneering co-housing projects in Austria.
Authors: Hirschberg R , Ruderer J , Röck M
Published: September 2022

“Limiting global temperature increase needs demand-side actions and lifestyle changes”, stated the IPCC in their Special Report on Global Warming of 1.5. Social innovation in the form of alternative models for spatial production and ownership can support such regenerative lifestyles and emission reductions in the emissions-heavy building sector. However, today’s real estate market hardly supports the development and realization of alternative housing models. In response, practice shows that innovative models of housing are often driven by the initiative of the (future) inhabitants. In this study, we investigate and analyze different models of social innovation in housing based on three recently completed building case studies in Austria. The case studies are situated in a broad range of spatial contexts: re-activating the countryside, vitalizing a newly developed neighborhood, or bringing new life to abandoned, existing buildings. They are showcasing strategies such as: innovative models of (co-)financing and (co-)ownership to provide affordable housing; the shared use of spaces, functions and resources for reducing environmental footprints. We provide insights as to how alternative housing projects are being established successfully, what models groups are exploring for governance, financing and ownership, and which other social innovation practices may support or enable the implementation of regenerative lifestyles.
Assessing the multi-layered value of urban development policy The case of developing a ‘creative’ and ‘circular’ district in the city of Utrecht
Authors: Velzing E-J , Vrijhoef R , Mens J
Published: September 2022

In recent years circular economy has become more important for the development of many places including cities. Traditionally, urban development policies have mainly been aiming to improve the socio-economic wellbeing of neighbourhoods. However, technical and ecologic aspects have their effects too and need to go hand in hand. This paper is based on an urban area experiment in the Dutch city of Utrecht. In order to assess urban area developments, typically rather straight-forward quantitative indicators have been used. However, it has proved more complicated to assess multifaceted developments of the area studied in this paper. With the City Model Canvas a multi-layered model is being used to better assess the impact of the urban development being studied. Key findings include that the project studied resulted in more space for companies from the creative industry and the settlement of local ‘circular’ entrepreneurs and start-ups, although it remains unclear to what extent these benefit from each other’s presence. The increase in business activity resulted in more jobs, but it is again unclear whether this led to more social inclusion. From an environmental point of view the project activities resulted in less raw materials being used, although activities and public events bring nuisance to the surrounding neighbourhoods.
Future proof real estate companies through sustainable development of institutional building stocks – Basics and tools
Authors: Worschech T , Lützkendorf T
Published: September 2022

The stakeholders and companies in the real estate industry are facing new challenges. They must react to megatrends such as climate change, resource depletion, shift in social values, demographic change and digitalization and at the same time comply with their responsibility to society and environment. In order to contribute to sustainable development and thereby ensure the future viability of the company, it is necessary to consider the social, environmental and economic impact of any business activities and decisions. Referring to the German market, a discussion will be based on the example of housing companies to show how sustainability aspects can be integrated into the instrument of portfolio analysis. The interactions between sustainability aspects resulting of the external business environment, the respective location characteristics, the building performance and the rentability and marketability as a success factor will be discussed. In this context, it will be explained how to react dynamically to a changing environment by using adaptable weighting factors and to local location and market requirements. As a conclusion, it will be discussed how the concerns of society, the cities (housing districts) and the tenants can be taken into account in addition to the economic interests of the housing companies.
The Paris Climate Agreement as Benchmark for Buildings and Companies
Authors: Piazolo D
Published: September 2022

The real estate market has a high obligation, but also many opportunities, to tackle climate change. The real estate sector is responsible for 40% of energy consumption and 36% of CO2 emissions in the EU. The global temperature must not rise by more than 1.5° Celsius compared to pre-industrial times in order to avert serious consequences of climate change. 195 countries agreed on this target by signing the Paris Climate Agreement in 2015 and thus also set the legislative framework and the desired direction of development for societies, companies and buildings. The Paris Climate Agreement can be used to establish a benchmark by showing which development routes are necessary to be compliant with the Agreement. It can be examined which adjustments are necessary to limit maximum global warming to 1.5° Celsius. By matching specific properties against such a benchmark, it can be worked out which properties are at risk of no longer being usable/rentable because they cannot meet the expected increases in environmental regulations, CO2 pricing, building standards and market expectations. This can be used to address transitory climate change risks.
Environmental Product Declarations (EPDs) of construction products in Spain: Current status and future challenges
Authors: Soust-Verdaguer B , Palumbo E , Llatas C , Acevedo A V , Hoxha E , Passer A
Published: September 2022

The current decarbonisation scenario demands a decrease in embodied and operational environmental impacts of buildings, wherein the Life Cycle Assessment (LCA) method and the Environmental Product Declaration (EPD) play a crucial role. The main objective of EPDs is to provide validated and geographically representative data to conduct LCA, since they play a major practical role in the application of LCA. However, development of EPDs in the European context remains irregular. Several countries, such as Germany and France, have a great number of EPDs of construction products, while other countries, such as Spain, present a much lower number. This study aims to analyse the existing EPDs of construction products developed in Spain, and to identify the EPD programs, the type of products (building system or element-associated), which LCA information modules are included, and the accuracy of the declared impact values. The results obtained show that ceramic cladding, gypsum plasterboard, cement, and clay products are those with the greatest number of EPDs. On the other hand, building service products have relatively few EPDs. Finally, several recommendations are proposed towards improving EPD development and challenges are detected.

Published: September 2022

Off-site prefabrication systems continuously gain attention in the building industry as they combine fast construction with fewer and more sustainable resources as well as minimize disturbance for occupants. In this direction, adaptable off-site prefabricated envelope components with embodied HVAC systems have been developed as an effective renovation solution. They can minimise thermal losses through the envelope while at the same time integrated HVAC systems efficiently maintain indoor thermal comfort conditions. In this study, a “Plug-and-Play” prefabricated envelope component incorporating HVAC systems is examined as a solution for the deep renovation of a typical single-family residence in Berlin, aiming to reach NZEB state. This versatile modular system, called SmartWall, can be installed either to the exterior or the interior side of the external wall, incorporating timber-based frame, boards and insulation, high-performance windows and a slim-type fan coil. The evaluation of this prefabricated system is investigated with respect to its energy performance both at component and building level, as well as its calculated embodied energy. The results indicate a reduction of 89% total primary energy highlighting that NZEB state can be ensured if the SmartWall application is combined with sufficient photovoltaic modules. The climate change potential contribution of such retrofit indicates a significant amount of embodied energy, which is nevertheless counterbalanced by the operational energy savings within the first few years after the implementation.
Ensuring proper management of building renovation based on an optimised decision-making model: Application in schools and social housing from southern Europe.
Authors: Serrano-Jiménez A , Díaz-López C , Barrios-Padura Á , Molina-Huelva M
Published: September 2022

One of the main challenges for architects and technicians is the efficient management of the built environment, in response to the growing deterioration and obsolescence in the building stock. This research introduces the design, development and application of a novel decision support system that assesses the multidisciplinary advantages or disadvantages of different intervention strategies, mainly focused on schools and social housing. The concept of the model aims to gather, interrelate and weight different renovation factors and variables, according to technical, social, energy and economic parameters, quantifying results on the impacts, consequences and benefits of each renovation strategy and providing practical outcomes in the design, construction, management and maintenance stages. This study uses schools and multi-family buildings, located in southern Europe, to apply and test the system iteratively in both building typologies, serving to adjust the calculation model and demonstrate its operation and replicability. The results are classified according to different intensity levels with their corresponding design alternatives along with a graphical output of results for decision-making. This model is expected to contribute to policy-making by introducing new theoretical and practical renovation guidelines, with a rational adjustment of proposals and ensuring effective and feasible action strategies in the built environment.

Meanwhile, it provides a reference to the development of a robust, effective, and stable system for addressing urban heat challenges during public health events.
Community Institution in Managing Floods and Tidal Drainage Infrastructure in Panggung Lor Sub-District, Semarang City, Indonesia
Authors: Wahyono H , Rahdriawan M
Published: September 2022

In general, the government’s provision of public infrastructure is carried out because it is part of the government’s obligation to provide public services. However, several cases show that an institution formed by the community manages the public infrastructure. One of them is the Panggung Lor Floods and Tidal Empowerment Management Association which is known as P5L (Paguyuban Pemberdayaan Penanggulangan Air Pasang Panggung Lor). The institution was created by residents of the Panggung Lor Sub-District in North Semarang District, Semarang City, Indonesia, to overcome and prevent floods and big tidal problems in the sub-district area. Since it was formed in 2000 until now, the institution has succeeded in overcoming its problems. This article examines the research results on P5L as an institution developed by the community to manage a public infrastructure that the government usually manages. Qualitative research is used to carry out the institutional analysis framework developed by Wageningen University and Research. This study indicates that since its establishment until now, P5L has been able to carry out the mandate given by residents of the Panggung Lor Sub-District and foster a sense of security against floods and high tides. The reason is that P5L can show good performance in 4 aspects, mainly that it can boost public confidence that the institution can manage the drainage system built on a community basis; However, initially, it was an independent institution formed and supported by the community currently it has become a partner of the government in managing parts of the urban drainage system; its services can create a residential environment that is free from floods and high tide and in green and clean conditions; as well as the supervision of its works is carried out directly by the community, as part of maintaining the trust given to the institution. For the institution’s existence to continue, the mandate given by the community must be upheld.

Street for Disabled: Form of Criticism on Inclusive Street Space in the Johar Market
Authors: Wungo Grandy Loranessa , Nathasya Ariel
Published: September 2022

The Johar Market, which is the center of Semarang City’s economic activity, should be able to accommodate all user activities, including the activities of disabled groups. However, the Johar Market Area condition is not safe for people with disabilities, especially access for pedestrians. Aspects of road material quality, safety, comfort, road circulation, legibility, distinctiveness, and familiarity are not achieved in the Johar Market Area. This research method uses descriptive quantitative methods, the Likert scale, multiple regression analysis, behavior mapping, interviews, and field observations. This study indicates that in determining the development of road space, it is necessary to identify the preferences of people with disabilities towards road space facilities, which must adjust to data on age, variety of disabilities, and travel destinations in the Johar Market Area. In addition, the condition of the road space facilities that have a wrong value is also mapped according to the criteria for the streets for disabled aspects. Thus, various recommendations were made for road space facilities based on the preferences of people with disabilities as road users in the Johar Market Area.

Published: September 2022

The COVID-19 pandemic has drastically changed the relationship between space users in the street, public spaces, and public facilities. Restrictions on physical distance (physical distancing) and activity (social distancing) are in place to prevent the spread of the Coronavirus. Borders on physical distance and access to public spaces do not reduce activity in these spaces. Public spaces must have an adaptive response to the spread of the virus while still implementing inclusive practices for all space users. Spatial adaptation patterns overcome the pandemic crisis in public spaces applied temporarily or permanently in the main areas where community activities are carried out. And now, in the transition of post-pandemic, when the city begins to open the pandemic, we hope people will remain comfortable and safe doing activities in public spaces from the spread of the Coronavirus. The specific purpose of this study is to explore the adaptation of community activities spaces that occurred in the centre of Semarang after the pandemic. This study uses a qualitative method with direct observation and interviews. This method captures the phenomenon of public spaces adaptation after the COVID-19 pandemic. The result is a temporary adaptation and viability pattern of community activity spaces in downtown Semarang in the COVID-19 pandemic transition. Hopefully, the finding can support the knowledge about sustainable public space after the pandemic.

The problem of small islands in the national border area related to development policy interventions is still lacking. Geographical position, raises problems in relation to regional accessibility. This is partly due to the remote geographical location, the economic scale of the business, inadequate transportation conditions, limited facilities and infrastructure such as electricity, roads, telecommunications, clean water and others. Small islands as an entity that has a size, special characteristics and vulnerabilities, so the planning and management of small islands require a different format from large islands. In connection with these problems, it is necessary to increase development interventions through the role of strengthening the role as a center for sustainable growth. Through a descriptive approach with scalogram analysis and clustering, determining the role as a growth center with a coverage area of influence can be done. economic and socio-cultural. The center of growth and grouping of islands is an approach taken to provide direction for spatial planning for small islands.
Analysis of the correlation urban systems and risk management floods, study case: Kaliwungu, Kendal Regency
Authors: Shafira Salmaa
Published: September 2022

Flood disasters in urban areas have become a frequent occurrence, especially in cities with high activities. The climate change phenomenon marked by increased rainfall also triggers the risk of flooding in urban areas. The flood disaster also occurred in the Kaliwungu District, which is one of the urban areas in the Kendal Regency, Central Java Province. The causes of flooding in urban areas is the failure of the drainage system to accommodate flood overflows. System failure in urban areas can affect the functioning of all systems in urban areas. This is supported by the high complexity of the urban system that influences each other, there are physical, social, and economic components of the community. There are two main questions in this research, namely “What forms the relationship between urban systems and disaster risk management?” and “How are urban systems and disaster risk management related to reducing flood disasters? So the aim this research is achieved of this study is to examine the relationship between urban systems and disaster risk management in an effort to reduce flood disasters. This research uses a descriptive case study method, which is based on qualitative material from various sources, including scientific articles, observation of the study site, and in-depth interviews. This study seeks to reveal the relationship between urban systems and flood risk management. The thing that links between urban systems and flood risk management is the main role of urban system functions in efforts to reduce flood disasters through comprehensive and complex disaster risk management. Thus, the urban system and disaster risk management must be interrelated in the preparation of urban spatial plans.

Imageability is the quality of a place that makes it recognizable, memorable, and different from other places. It determines the character and identity of city space. On the other hand, slum settlements are a severe problem in several countries worldwide. Urbanization makes urban space denser and causes disorder if there is no good urban spatial development. This condition then affects the image of the city, which becomes less good, disorganized, and has no character. In its role, good quality (non-slum) urban settlement will improve the image of the city. However, in the context of slum settlements in Indonesia, under certain conditions, it can have good imageability as part of the identity of urban settlements. This paper aims to assess the imageability of the slum area of Mojo Village, Surakarta City, which will be used as a basis for settlement upgrading. This study uses a qualitative method with a visual assessment survey using the main parameters of the condition of the open spaces and buildings. A visual assessment survey is a survey to assess visual quality by observers with predetermined assessment criteria. This study found that predominantly settlement neighborhoods have low imageability, but some places have high imageability.

Land cover change is a phenomenon that often occurs along with population growth and economic activity. This phenomenon not only occurs in urban areas but also penetrates into suburban areas, which incidentally have an important role in the water flow system. The same condition occurs in the Garang Watershed, Semarang City, where changes in land cover have begun to penetrate the water catchment area. Land cover change in the Garang watershed system will certainly have consequences for potential water-related disasters, and it will get worse due to climate change. Climate change in many places has triggered a water-related disaster or hydrometeorological disaster. Land cover change and climate change are conditions that cannot be avoided but can be managed so that they do not have a negative impact on the community. To minimize the adverse impacts of land cover changes and climate change is to provide land use directions that can reduce the threat of hydrometeorological disasters so that the sustainability of the ecosystem in the Garang watershed can be maintained. One approach that can be used in the framework of sustainable land use modeling is the spatial regression method. The results of the analysis show that the role of vegetation and water reservoirs can significantly reduce the potential hazard of hydrometeorological disasters.

Resilient and sustainable infrastructure development is necessary to support innovative industries. Batang Regency is one of the regencies on the island of Java that is currently intensively building infrastructure to prepare the Batang Integrated Industrial Estate (KITB). Therefore, the government also supports this Presidential Regulation Number 79 of 2019 and Presidential Regulation No. 109 of 2020, which observes the development of the Batang Regency Integrated Industrial Estate. When the Covid-19 pandemic hit Indonesia in early March 2020, many changes occurred in the infrastructure development process. Some infrastructure has been temporarily suspended due to the Covid-19 pandemic. Of course, this will be followed by a decrease in emissions due to limited movement and infrastructure development there. This study wants to analyze how the air changes from the beginning of the pandemic until 2022. The air changes will be seen by monitoring NO2 formed from emissions from cars, trucks, buses, and industry. This is intended to measure/identify how the pattern of air changes considering the Batang District is passed by the Pantura road so that there is a high intensity of movement. The method used is spatial analysis with google earth engine Sentinel 5P images. The result of this study can provide input monitoring emissions related to technological advances in the era of open data.
