Abstract
This research aims to demonstrate a self-reliant home based on the sufficiency economy concept that can be located within a city with limited space such as Bangkok. The demonstration house was located in Kasetsart University, which was constructed from a container module with wall insulation (sandwich panel) and use natural ventilation to reduce energy consumption. In addition, a 1.2 kW poly-crystalline silicon photovoltaic system connected to the Metropolitan Electricity Authority grid to produce electricity. Vegetables such as Chinese cabbage, morning glory, green lettuce, lettuce, and mushrooms were grown for consumption and sale. Preliminary data such as temperature, electric generated from renewable sources were collected and simulated for further development of a self-reliant house based on the sufficiency economy concept.
From data collection, electricity generated from photovoltaic system can accommodate all appliances without needs of electricity from the grid. Furthermore, agricultural products around the house were grown enough for daily consumption and can be sold with slight incomes. For the thermal comfort, the house was too hot in daytime. The temperature can reach maximum at 38oC due to the high solar radiation, which the lack of an air conditioning system was not installed in this house. However, this house was cooled down into the thermal comfort range at 25oC in the evening, which a solar battery fan and exhaust fan can be used to improve nocturnal comfort and indoor air ventilation. Form every aspect studied in this research, it can be concluded that a self-reliant home is possible to build and live even in the confine space such as Bangkok area.
