Developing thermal comfort model through regional budget expenditure analysis towards low energy consumption in public building facility (case object: government building in north and south of Jakarta)

摘要: Building efficiency policy has implemented Indonesia. However, energy consumption in building sector remains significantly increased. Jakarta Government relied on AC providing a comfortable condition for its service it consumed 57% of total consumption. Current available monitoring method based the expensive electrical device, so new using regional budget expenditure is developed this research. This study established: Field (6 buildings), analysis (313 buildings) thermal comfort and 112 administrative office equipped with Natural air ventilated (NV) Air Conditioned (AC) 224 occupants/building manager were taking part Quantitative used research variables: (Air temperature, Relative humidity, radiant velocity, personal clothing index) Fanger’s Predicted Mean Vote (PMV) calculation. Another variable government standard Energy Consumption Index (IKE) through analysis. During an early stage, shows 6 out buildings (electricity) categorised as ‘extravagant.’ higher IKE caused by too cold temperature setting, underperformed Conditioning System, envelope ventilation or ‘inappropriate’ orientation (facing east-west).
