SB-1.2 Low Energy Building Demonstration Projects

The Pluit Residensial House occupies a site area of about 250 square meters and was completed in March 2013. The building has 3 storeys and 1 flat roof for Solar cell, 1 cold Water Tank, 1 hot water tank, 1 VRF Air Conditioning unit with hot water generation, 3 parabolas, 1 Pyramid meditation,, 2 out lets voids, 1 sky lighting, Green roof and 1 Gazebo for leisure area. A total gross floor area of 781 square meters.

This Pluit Residential House is a house designed using Green building and high performance sustainable low energy building concept to create a harmonized relationships among the human, environment and bio-climatic, is located in the northern part of the heart of Metropolitan City of Jakarta which has 250 sq meter of land, 3 stories buildings and 1 flat roof with the total gross floor areas of 781 sq meter, and facing southern part.

  1. Using bio-climatic of Jakarta, Sky lighting concept to create natural ventilation with air speed of > 0.5m/s and day lighting on none air conditioned area and air conditioned area during the day time to save both the electric energy for AC, fan and lighting.
  2. Using modified VRF air conditioning unit to produce free hot water (up to 50 ºC) from hot refrigerant gas.
  3. Using new concept of 2 tanks (an insulated hot tank and cold water tank with equalized pipe) to distribute with equal gravitation pressure of water system in the house without using a pump.
  4. Installed 48 solar Panels @ 50W output to generate 2400W electricity during the day time, average daily electricity produced by these Solar PV is 12 kWH and total 4380 kWH of electricity per annum or $526.
  5. The average electricity from the grid is 17065 kWH/year (8760 hours) or 3896 kWH/year (2000 hours) or Energy Efficiency Index based on air conditioned area (212 sq meter) is 18.4 kWH/sq meter year (2000 hours). EEI based on gross area (781 sq m) will be 5 kWH/sqm yr.
  6. 98% of the lighting systems in this house are using LED light with the average 3.4 w/sq meter in common area and 2 w/sq meter for gross area.
  7. Use Rainwater gardening on the ground yard to preserve the water for running to the drainage.
  8. Use green roof and solar panels on the flat roof to reduce RTTV to the lower floors.
