COMMUNITY EMPOWERMENT TOWARDS ENERGY SAVING OF SETTLEMENTAT RT.03 / RW.01 KEL. PETUKANGAN UTARA KEC. PESANGGRAHAN JAKARTA SELATAN

Dense settlements in urban areas are one of the problems in DKI Jakarta. RT.03 / RW.01 Kel. Petukangan Utara, Kec. Pesanggrahan Jakarta Selatan is one of the densest settlements in DKI Jakarta which is located side by side with Universitas Budi Luhur. Based on SNI 03-1733-2004, the level of population density in the region is included in the category of High Density. This can be seen from the houses lined up along the road with little provision of Green Open Space. The community develops the need for building area by maximizing the area of land for building. This impacts the lack of air circulation in accordance with SNI-14-1993-03 about the thermal comfort area of buildings which are conditioned for Indonesians, as well as the lack of lighting in accordance with SNI 03-6575-2001 regarding illumination standards for the light of a room.With thermal comfort and illumination that is not in according to standards in the region, a Community Service activity was held by the Faculty of Engineering of the Universitas Budi Luhur to add community knowledge about how to make thermal comfort and illumination in homes using energy efficient. Thermal comfort can be fulfilled by making vertical greening on limited land, While the comfort of illumination can be fulfilled by using LED lights. The activity uses community empowerment methods, so that the community can independently make vertical greening in their respective homes and know the benefits for thermal comfort and can use LED lights in their respective homes and know the benefits to save electricity. The results of the Community Empowerment Towards Energy Saving Settlements at RT.03 / RW.01 Kel Petukangan Utara Kec. Pesanggrahan Jakarta Selatan, is that the region has vertical greening as a natural air conditioning system and uses an LED lighting system as an energy efficient lighting.

Abstract The rapid development of urban areas in general has a negative impact on built environmental. The decrease of green open space is cause by increasing the need of space for human activity. The reduced area of green open space in Denpasar City, especially in private green open space in the Kesiman Kertalangu area, causes environmental quality to decline. Reducing the area of green open space can cause urban problems, such as increasing city air temperatures. Therefore, it is important to know the role of private green open space in residential yards for increasing thermal comfort in the Kesiman Kertalangu area. For this study the method used is a qualitative research method with a descriptive case study approach. The aim of this study is to determine the role of private green open space in residential yards in term of thermal comfort. The results show that in residential yards that have relatively large areas of land, the existing private green open space conditions are quite optimal. However, in residential yards that have limited land area, the availability of green open space is very minimal. The existence of private green open space in residential yards at the Kesiman Kertalangu area in general is not able to work optimally in reducing temperatures to create a suitable thermal comfort for the environment.

Green Open Space is a component of landscaping that greatly affects urban air both directly and indirectly. The ideal standard minimum area of green open space is at least 30% of the total area of the city.The study used a spatial analysis method through the approach to calculating the Normalized Difference Vegetation Index (NDVI) for vegetation cover. Overlay analysis of GIS vegetation cover maps with the Ambon city spatial pattern map, has produced a map of the city green open spatial model, which shows a picture of existing corridors of green open space patterns, building spatial patterns, and non-vegetation spatial patterns (vacant land) .The results of the analysis of the green open space model map recommend the need for areas with urban park areas, park spots areas, and tree corridor areas planted on either side of the road. Inventory method, analysis of spatial and observations carried out at nine sampling locations, showed that the location of Ambon City's green open space was ± 1.115.900 m2 or 111,59 ha, with cover of understorey vegetation (grasses and saplings) 16,31 ha. Estimated carbon content of understorey vegetation (grasses and saplings) 52,49 kg/ha and 883 kg/ha of pole and tree vegetation. Normalized Difference Vegetation Index (NDVI) in nine sampling locations of Ambon City's green open space, for the area of vegetation cover is 61.58 ha or 58.31%, building area 39.63 ha or 37.52% and vacant land 4.40 ha or 4.17%.

Dense settlements in urban areas are one of the problems in DKI Jakarta, due to the discrepancy between the area of land and the population. RT.03/RW.01 Petukangan Utara Village Pesanggrahan Sub-district South Jakarta is one of the densest settlements in DKI Jakarta which is located next to Universitas Budi Luhur. Based on SNI 031733-2004, the population density level in RT.03/RW.01 of North Petukangan Village, Pesanggrahan Subdistrict, South Jakarta is included in the category of High Density. This can be seen in the dense residential row with the lack of Green Area. The community develops houses by using the land for building and pavement. This impacts the lack of healthy air circulation by SNI-14-1993-03 about the thermal comfort area of buildings for Indonesians. With thermal comfort that is not by SNI standards, the Community Service activity was made by the Universitas Budi Luhur Architecture Department to increase public knowledge about thermal comfort in homes with limited land. Thermal comfort can be achieved by creating a vertical garden on less land to produce cool air in residences. The activity uses the method of community empowerment so that the community can independently create a vertical garden in their homes and know its benefits as thermal comfort in the building. The results of the activities of the Community Empowerment Towards a Green Settlement on RT.03/RW.01 North Petukangan Village Pesanggrahan sub-district of South Jakarta is such settlements have a vertical garden as a natural air conditioning system. With the vertical garden as a natural air conditioning system, it can reduce the use of energy for artificial air conditioning, so that it saves energy and produces better air quality.

This study assesses Human Thermal Comfort in two selected areas: a Green Infrastructure (GI) area represented by a garden and a high-rise building area, in the Central Business District (CBD) of Melbourne, Australia. Three-dimensional microclimatic modelling software, ENVI-met version 4 was used to simulate the microclimate. The indices of Predicted Mean Vote (PMV), Physiological Equivalent Temperature (PET) and Universal Temperature Climate Index (UTCI) were used to quantify the level of thermal comfort in the research areas. The simulation results showed that at midday, the difference in temperature between the garden area and the high-rise building area was approximately 1°C. Increasing temperatures at midday led to a change in the level of thermal comfort for both the areas, even though it was not significant. In general, the thermal perception in the GI area was slightly ‘cooler’ than in the high-rise building area. The results of the study indicated the important role of GI in improving the thermal comfort in urban areas.

Adequate Coverage

A community garden (CG) can generally be defined as a piece of land gardened collectively by a group of people that grow their produce on shared lots that have been divided into smaller plots. Some gardens are grown collectively, are divided into different plots for individual and family use; CGs are usually located in urban or peri-urban areas. As a growing portion of the urban open space network, CGs are contributing to land preservation, access to open space, and sustainable re-use of vacant land. They promote healthy communities and provide food security for many. In this context, the object of the study are the municipal community gardens (MCGs), a specific typology of CGs provided for land-use planning legislation and practice as an urban service with social function, made available to the community by the municipalities and assigned to be cultivated to citizens (usually seniors/retired people). In particular, the study aimed: i) to evaluate the presence of MCGs in the città metropolitana di Milano (the former province of Milano); and ii) to define criteria for new MCGs settlement, using existing geo-database and geographical information system to make it replicable in other settings. For the first topic the 133 municipalities of the former province of Milano (excluded the city of Milano) were analysed. Only 59 municipalities had presence of MCGs. The average area per capita of MCGs is 0.68 sq.m/inhab. (if we exclude Rodano, an outlier with 35 sq.m/inhab.). An overlay with land use map has permitted to define the relationships between the MCGs and their surrounding territory. The major part of MCGs are included in urban or suburban areas. For the second goal, the land area to be allocated for new MCGs was assessed for each municipality, comparing area of existing MCGs and a minimum required area (calculated on the basis of the inhabitants number). Finally a method was proposed to locate the new MCGs areas. Criteria used to identify suitable areas for new MCGs were: proximity to the road network inside residential areas, suitable land use, not high land capability. In this way it has been defined for each municipality the number of MCGs to be realized and their area, and located the potentially suitable sites. Choosing between the identified suitable areas, the new MCGs were homogeneously located on the territory of each municipality in order to ensure adequate coverage of residential areas; the degree of coverage has been verified through a service area analysis. The proposed method seems to be useful for the MCGs settlement at metropolitan/provincial level.

It is important to improve residential thermal comfort in the high dense cities, in which wind environment is crucial. Waterside buildings take an advantage of micro-hydrological-climate in summer that should be used to enhance residential thermal comfort especially in the subtropical region. In order to propose design approaches according to the outdoor thermal comfort of the waterside residential, a case study of Shenzhen She Kou residential district has been made. It focused on various factors that could have influence on wind environment for improving thermal comfort. Using wind velocity ratio (ΔRi) criterion, factors of building development volume, building direction and layout pattern, open space arrangement etc. have been broadly explored using FLUENT simulation. To planning parameters, the Floor Area Ratio (FAR) is significantly influence wind environment, the smaller FAR is better. To the vertical layout of the buildings, multi-storey layout and multi-storey & sub high-rise mixed layout would provide better wind environment. To the horizontal layout, the determinant is better than the peripheral. Other factors such as the buildings’ direction towards the road, buildings’ height, and open space setting, have influence on wind environment yet. In general, the more benefit of design layout for wind breezing, the better wind environment it could get

Human Thermal Comfort

Building energy savings and occupant thermal comfort are the main issues in building technology. As such, the development of energy-efficient heating, ventilation, and air-conditioning (HVAC) systems and the control strategies of HVAC systems are emerging as important topics in the HVAC industry. Variable refrigerant flow (VRF) systems have efficient energy performance, so the use of VRF systems in buildings is increasing. However, most studies on VRF systems focus on improving mechanical efficiency, with few studies on energy-efficient control while satisfying the thermal comfort of occupants. The goal is to estimate the energy-saving potential of adjusting the temperature set-points and dead-band (range) in VRF air-conditioned building. To do so, we analyzed the influence of control strategies of a VRF system on human thermal comfort and energy consumption using a simulation method. The results showed that energy consumption can be reduced by 25.4% for predicted mean vote (PMV)-based control and 27.0% for the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) comfort range control compared with the typical set-point temperature control of a VRF system. The indoor thermal environments of the analyzed control strategies are controlled in the thermal comfort range, which is based on a PMV at ±0.5. Compared with the typical set-point control, PMV and ASHRAE comfort range-based control reduced the operation time of the compressor in the VRF system.
