Stay cool without fossil fuel. A passive eco-cooler for low-income population in informal settlements
Authors: Dabaieh Marwa , Zakaria Monica Michel , Kazem Medhat 
Published: November 2021

Abstract
With climate change severe events, more and more vulnerable populations suffer from extreme heat waves. This paper presents a hands-on experimental idea for testing vernacular passive cooling strategies using traditional Shisha clay funnels for the Egyptian hot dry climate. Several clay funnels were investigated in terms of shape, size and form. The clay funnels were measured and simulated for their efficiency in accelerating air flow inside residential units and ability to enhance the air velocity if used combined with cross ventilation strategies. Computational Fluid Dynamics (CFD) simulations were conducted in ANSYS Fluent to understand the airflow behaviour inside the simulated test shoe boxes resembling living rooms - using the standard k-∈ turbulence model - for single and multi-units’ configurations. Followed by experimental test cells application for the cooling system and monitoring for testing thermal performance. The simulation results showed significant enhancement in air flow and air speed inside the test room compared to conventional windows, while the test cells monitoring showed an average reduction in indoor temperature and humidity with 2 degrees and 15 % respectively. Further monitoring is needed for other alternations of the eco-cooler funnel design for better performance.
Thermal performance of a non–segmented and segmented tall atrium in hot and humid climate
Authors: Pawar Priya , Zhang Deying , Wu Xiaoying , Lang Werner 
Published: November 2021

Abstract
The study was designed to quantify the thermal conditions in tall atria in office buildings to serve as a starting point towards understanding their performance. The simulation study of a non-segmented and segmented atrium of 250 m height reveals indoor air temperature, wind velocity contours and wind pressure coefficients at various heights of each atrium type. In a hot and humid climate like that of Singapore, the internal temperatures within each atrium stack remain constant at 27°C. However, the wind velocity in the non-segmented atrium (of 0.5 - 0.7 m/s) is lower than acceptable (0.9 m/s) for human occupancy. Adding segments and a larger inlet to the atrium solves the problem of low wind velocity without increasing the effective ambient temperature within the atrium stack. Additionally, the segmented atrium offers the advantage of displaying lower buoyancy forces by lowering the pressure differential within a tall stack thereby providing better comfort conditions.

Authors: Babourova O V , Frolov B N , Khetzeva M S , Kushnir D V 
Published: November 2021

Abstract
Plane gravitational waves in the Riemann space of General Relativity is considered. The criterion of plane gravitational waves is used based on the analogy between plane gravitational and electromagnetic waves. The Theorem is proved that the action of the Lie derivative on the plane wave curvature 2-form in the direction of the vector generating the invariance group of this wave in the Riemann space is equal to zero. It is justified that the gravitational waves can be used to transmit information in the Riemann space.
Gravitation in Theory of Space-Time Film and Galactic Soliton
Authors: Chernitskii Alexander A 
Published: November 2021

Abstract
The scalar field of extremal space-time film is considered as unified fundamental field. Metrical interaction between solitons-particles as gravitational interaction is considered here in approximation of a weak fundamental field. It is shown that the signature of metrics {-,+,+,+} in the model formulation provides the observable gravitational attraction to a region with bigger energy density of the fundamental field. The induced gravitational interaction in the space-time film theory is applied to stars in a galaxy. The conception of galaxy soliton of space-time film is introduced. A weak field asymptotic solution for a galaxy soliton is proposed. It is shown that the effective metrics for this solution can provide the observable velocity curves for galaxies and explains their spiral structure. Thus a solution for so-called dark matter problem in the framework of space-time film theory is proposed.
Resilient Experiments in Rural Housing: Architectural Experiments in Planned Housing
Authors: Galford G , Tucker L M 
Published: November 2021

Abstract
Single family houses contribute substantially to climate change in the US and other parts of the world. In the US specifically, most housing has been designed by builders and developers. The motivation has not been sustainability and a knowledge of how to design net zero energy and net zero water dwelling is not commonly understood. This paper seeks to use a historical model as viewed through the lens of the Living Building Challenge to demonstrate how an architect designed historic example might provide a way of implementing a cutting-edge approach to sustainable housing today. Arthurdale was an early 20th century housing experiment that was conceptualized to provide for sustainable living in rural Appalachia. This paper presents the history of the region, an overview of the houses and the Living Building Challenge and then analyses how this historic prototype might model a sustainable housing development today using the Living Building Challenge system.
Commoning: Towards the Eviction of Kampung Bidaracina, Jakarta
Authors: Fikri Muhammad Luthfi , Herlily  
Published: November 2021

Abstract
Over the past decades, flood control has been providing the rationale for evictions in Jakarta. Underlying this study is a set of notions where the eviction plan would bring up uncertainty to their commons: the risk of possible destructions of their commons, the uncertainty of livelihood, or the dubiousness of securing a decent amount of compensation. Considering that, this study is trying to identify the scope of commons and commoning in long-envisioned yet unimplemented eviction of RW 04 Bidaracina, Jakarta, as well as to understand its relation to resilience in several forms. We conducted interviews to understand the aspirations of the residents of RW 04 Bidaracina to answer the questions of this research, which concern mainly on how the notions of commoning are manifested in a community expecting a rather uncertain eviction. The result corresponds favourably with existing studies on kampung as urban commons.

Authors: Mahardika I N U , Ayu Gusti , Suartika Made , Saputra Kadek Edi 
Published: November 2021

Abstract
Community groups who live in traditional settlements mostly have a wealth called genius loci, which actually has very insight into the preservation of the natural and cultural environment. Bali also has several unique traditions that are not only in terms of settlement layouts, but are unique in terms of preserving the natural landscape. Meanwhile, there are some areas in Indonesia that are not able to maintain environmental sustainability, which is indicated by the continued increase in deforestation rates which are a sign of the deteriorating quality of the surrounding environment. Based on this, this article discusses the traditions applied in landscape conservation in Penglipuran Bangli village. This research was conducted using a qualitative descriptive method with a case study approach. To preserve the natural environment, there are several traditions that are still maintained and implemented consistently, including traditions: Preserving village forests, keeping the environment clean, telajakan karang kerti, may not use vehicles on the main village corridor. The application of local traditions related to environmental preservation is carried out consistently and with full awareness by both the community and the prajuru as leaders in the Penglipuran Traditional Village. The success of nature conservation cannot be separated from the clear, firm, consistent application of awig-awig accompanied by sanctions, as well as public awareness of the importance of landscape conservation.

Published: November 2021

Abstract
Green open space is a space is dominated by an open environment, it can be in the form of parks, green lines, or recreational facilities. The benefits of having green open space in an area are that it can improve the quality of the environment, create environmental harmony and balance, provide freshness, a place for water absorption, and as a component of the structure and space of the city. In the development of an area, the ecological value of the land is often sacrificed to be replaced with a more economical function, such as the construction of additional facilities in the tourism area. To maintain the benefits of green open space, this study discusses the increasing use of green open space in the construction of tourism supporting facilities, especially those in Giriloyo Batik Village. This research is expected to be used as a consideration for the management of the Giriloyo Batik Village area, which later on the area can be managed properly, both in terms of physical and non-physical. This study used qualitative research methods. The impact of the construction of tourism support facilities in Giriloyo Batik Village shows that in the last 14 years there has been a change in land use. In particular, the change in the use of green open space as a support for tourism areas of 3 hectares or 3% of green open space is now used as built-up land. The tourism facilities in question include Gazebo Batik, cottage industries, dam, parking areas, and secretariats that put pressure on the land.

Published: November 2021

Abstract
Advertising media uses a lot of public space as a place to advertise which can reduce the function of public space in urban areas. This study aims to determine the use of urban space as a medium for outdoor advertising that interrupts and reduces the function of space. This study uses a qualitative approach with descriptive data analysis methods. The four intersections on Jalan Raya Dalung have interrupted the function of public spaces, including functions as pedestrians (pedestrian paths), telajakan (as an element of reforestation), protecting the environment, and as borders. Inappropriate placement of advertising media creates a chaotic impression and visual chaos.
