Published: December 2019

Abstract
One of the smart city indicators is a smart environment. Smart environment is a setting which can be a catalyst for its citizens, support them to be aware of a local engagement in managing their existing natural resources. The local engagement is not only shaped by formal strategies, but also by local wisdom. Local wisdom is a community understanding that is used as a reference in daily life activities. Based on its history, the Malay Kampong (Kampung Melayu) Semarang which was formed in 1743 has strong local wisdom as a basis for arranging the district. Settlement patterns based on ethnicity and culture, building patterns that are sensitive to the floods and tidal ranges, multicultural-based district, make this region able to survive hundreds of years to maintain its existence and can be a representation of the smart multicultural environment in Semarang. The current environmental degradation in this area is the basis for the research. Is local wisdom still maintained here? Or is there a shifting meaning of local wisdom at this time? This study aims to explore the role of local wisdom of Malay Kampung Semarang as a representation of a smart environment. This study combines quantitative and qualitative approaches. To achieve this goal, it is necessary to identify the influence of local wisdom in Malay Kampung Semarang on flood resilience and tidal. The analysis of the smart environment model is based on the interaction of wisdom and influence on the district arrangement. The result of the study shows that local wisdom is an effort to improve the living place to be more sustainable in the event of flooding and tidal. Efforts made to elevate the floor of the building, height of buildings, elevate the street, build houses with a stage model, and make the second floor of the house represent a smart environment in the form of sustainable urban planning in the Malay Kampung Semarang.

Authors: El Gendy Marwa Abdelkader 
Published: December 2019

Abstract
Software and methods (such as Parametric modeling) could be effective for architects and engineers to improve the design and reparametrize modeling. These methods will help develop the best solutions for improving the sustainable design. A challenge for designers is to integrate daylight and shade study with optimization into the design process. For achieve accurate results, most of the building environmental performance simulation tools need a large amount of time and repetition. Furthermore, the combination of daylight and energy performances has always been an issue, as different software packages are needed to present detailed calculation. This paper describes the control of codes and calculations that modern designers can use to produce new structures as opposed to specifically design them. The paper reviews paradigm shifts in architecture, and gives a description for parametric design and parametric design types, Also, The Paper introduces Eco-cell simulation study using Rhino and Grasshopper as a new tool of parametric design. An Eco-cell is an interactive hexagonal cell that achieves environmental concepts. The paper explores this environmental study by using Ladybug plug-in to study sunlight analysis and radiation analysis. EPW file is used to draw the sun path and finally the simulation study to control the whole cell structure. The Paper used the evolutionary solver Galapagos to attain the most effective result in daylight quality by controlling interactive hexagonal cell structure.
Simulation-based energy efficiency retrofit of listed building ensembles: An alternative solution with a climate envelope
Authors: Karasu A , Hantouch Y , Steffan C 
Published: December 2019

Abstract
This article draws an innovative architectural solution for enhanced energy efficiency by retrofitting ensembles of listed buildings. A combination of various simulation tools and a self-developed feasibility tool has been used at the preliminary design stage to develop a measure at an urban scale within the campus of TU Berlin.
First, a potential analysis for 48 buildings within the campus has been run using multi-zone simulations with Modelica. Afterward, with the feasibility analysis tool based on Python, called HCBC-Tool, all possible measures have been ranked at the pre-stage of this project. As a conclusion, by buildings where standard measures are not feasible, alternative solutions have been developed using DesignBuilder, where not only energy-related issues both also architectural ones were considered. Additionally, energy substitution measures have been simulated with SunnyDesign to complete the concept. Here, a “climate envelope (CE)”, which is an additional transparent envelope covering the buildings partially, has been developed for a building ensemble built between 1883-1975. Enhancing the energy efficiency of all five buildings within the ensemble with standard measures up to the new building level according to the German energy efficiency regulations would reduce their energy consumption app. 32%. Nevertheless, this regulation is not mandatory by listed buildings. Besides, 12,152 m2 external envelope surface should be retrofitted. By comparison, a CE could lead to enhanced energy efficiency and it alone could reduce the energy demand of the building ensemble up to 33% and combining it with standard measures could increase the savings up to 60%.
The impact of climate change on Building Energy Simulation (BES) uncertainty - Case study from a LEED building in Egypt
Authors: Elrawy Omar O. , Attia Shady 
Published: December 2019

Abstract
Climate change and global warming are two major concerns over the globe today, and the rapid change in climate became more sensible as it impacts diverse industries and disciplines. Buildings share of the global energy use exceeds 40%, and buildings’ Green House Gas (GHG) emissions resembles one-third of global GHG emissions; hence, Building Energy Simulation (BES) process became an essential step during building design, to study and minimize whole buildings’ energy use, and consequently minimize buildings’ carbon footprint. A significant and underestimated input to the BES process is the weather data; BES process normally uses historical weather data in the form of a weather file to simulate the building’s outdoor conditions, those outdoor conditions impacts the amount of thermal load on the building, therefore they significantly impact building’s estimated thermal comfort and annual energy use. With the rapid change in the outdoor weather conditions year after year, using those historical weather data files must be questioned, as they impact the estimated energy use, and consequently put what’s deemed as the “optimum energy use” in question. Using those historical weather data is hence expected to increase BES degree of uncertainty. This paper studies and quantifies the impact of weather data accuracy on building’s annual energy performance. The paper follows an empirical research approach by simulating an office building located in Cairo, Egypt. The study relies on using a typical weather data file and real weather files to run and compare two simulations for the same case study. Finally, the paper quantifies the impact of weather data’s accuracy on the total annual energy use by comparing both simulation results.

Published: December 2019

Abstract
The demand for electrical energy had grown tremendously over the last few decades. The 2019 annual report by electricity sector of India shows that India is the third largest consumer of electricity in the world. Studies revealed that buildings are major consumers of electricity, in which residential buildings consumes the most. Tremendous increase in electricity demand are anticipated in Indian residential sector in the coming years due to development plans such as Power for all policy. Studies depicted that residential buildings have an energy saving potential of about 30-50% and most of the previous researchers had focused only to replace the electrical appliances in the constructed facility and had ignored the design features of the building to minimize electricity consumption. The present study therefore focused on reducing the energy use in residential sector of India by simulation-based optimization of buildings at its design stage. Design Builder software version 6.1.0.006 with Energy Plus simulation engine 8.9 was used for the study. A two storied residential building in Kochi, Kerala was considered for the study. The building model was validated using previous electricity bills and was then retrofitted using Energy Conservation Building Code (ECBC). The model was simulated for eight different orientations for different cases in five different climatic zones in India. East orientation was found to be the best orientation for all cases except cold climatic zone. The percentage saving in annual electricity consumption and cost of electricity bills that could be saved by opting the best orientation were also found.

Silicon nitride-based ceramic composite materials for corrosion-resistant rolling bearings
Authors: Pakhomova S A , Povalyayev A I 
Published: December 2019

Abstract
The technological process of obtaining material and manufacturing ceramic rolling elements of the bearing is considered. The composition of a silicon nitride-based ceramic composite material was investigated. The chemical inertness of ceramic materials determines the low adhesive wear in the mating parts of the supporting elements and makes it possible to use the rolling elements of the bearings in conditions of poor lubrication. Bearings with ceramic rolling elements show excellent running performance in emergency conditions and do not lead to sudden failures. The excellent corrosion resistance of ceramic materials allows them to be used in aggressive environments. The combination of such properties is accompanied by a decrease in temperature in the working area and allows the use of higher rotational speeds. The feasibility of using ceramics for the production of balls for bearings and the main advantages of using a ceramic material compared to metal products are shown. The process mode of hot pressing of blanks of ceramic rolling elements has been developed.

Published: December 2019

Abstract
Composites are widely used as engineering structural materials in different technical areas, given their higher mechanical properties combined with their smaller weight as compared with the “pure” materials. An important characteristic of a composite is a set of its elastic properties. To determine these properties, both experimental methods and mathematical simulation are used. Due to large material costs and time expenditures inherent in each experiment (fabrication of the material and the test sample, performance of the experiment and processing of the results), on the material design stage, as well as when determining the material application area, preference is given to the simulation methods.This paper is focused on the comparative analysis of the available mathematical simulation methods in terms of performance study of the unidirectional fiber-reinforced composite in the plane normal to the fiber orientation. For illustrative purposes, composites with two different kinds of matrix, polymeric and metal, are considered.
