IEA Solar Heating & Cooling Implementing Agreement - Task 13 (Solar Low Energy Buildings) was an international effort organised by one of the International Energy Agency's Implementing Agreements to build several solar low-energy houses. This took place between 1989 and 1993(?). The Implementing Agreement for a Programme to Develop and Test Solar Heating and Cooling Systems is one of 40 research and development and deployment programmes, which are at the core of the IEA's International Energy Technology Co-operation Programme. The idea behind Task 13 was to push construction technology towards its limits to achieve the lowest possible total purchased energy consumption. Task 13 was part of the IEA ''Solar Heating and Cooling Programme'', to test the designs and techniques, and to monitor their performance. ==Design== On average, the houses were designed to required 44 kWh/m², 75% lower than the average 172 kWh/m² that would have been required had the houses been built to normal standards. (Analysis of 11 of the houses in use indicated that total savings made in practice was actually 60% ()).The 44 kWh/m² resulted from: *Electricity – 18 kWh/m² *Space heating – 14 kWh/m² *Water heating – 11 kWh/m² *Cooling – 1 kWh/m² In addition there was an average solar contribution designed to average 37 kWh/m², from a combination of passive solar gains, active solar, and photovoltaics. The buildings were constructed to be airtight, be superinsulated to roughly double normal standards, and to minimise thermal bridges. Masonry and several timber framed methods were represented, along with a novel steel strengthened polystyrene block walls were used. The Berlin "Zero Heating Energy House" included a 20m³ (700 cubic feet) seasonal thermal store.() 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「IEA Solar Heating & Cooling Implementing Agreement Task 13」の詳細全文を読む スポンサード リンク
