Bioclimatic Solar Home Design in Bangkok, Thailand


This research aimed to study the bioclimatic home design in Bangkok, Thailand, and the installation of Photovoltaic System on the roof. By collecting the climate data from sample single-story house in Bangkok, having an open courtyard of dimension 4.00 x 4.00 meters. It is observed that the key of bioclimatic solar home design comprises of house orientation with the pitch roof of 15 degrees south, and an open courtyard that gives good ventilation, adequate natural light and a suitable landscape. The garden contains various species of plants that are homes for small creatures such as squirrels and birds, and together formulating a biotope and balanced ecological system. By connecting the courtyard to kitchen, dining and living area creates a bond between the house inhabitants and nature, promoting a healthy emotional and physical well-being. The courtyard generates a micro climate in which helps reducing the ambient temperature. When adapting the bioclimatic home with 30 square meters of Photovoltaic System installed on the roof, using grid connected PV system. The inverter, with maximum power generation capacity of 3.3 kW, can supply electrical energy at an average of 12kWh/day. This helps in lowering the monthly electricity cost by 30% and decreasing the amount of carbon dioxide gas consumed in the electricity process by 8.8 kilogram per day. The return on investment will be about 10 years and 7 months. This will help to further develop zero energy home design.
