The idea behind Task 13 was to push [[construction]] technology towards its limits to achieve the lowest possible total purchased [[List of energy resources|energy]] consumption. Task 13 was part of the [[International Energy Agency|IEA]] ''Solar Heating and Cooling Programme'', to test the designs and techniques, and to monitor their performance.

On average, the houses were designed to requiredrequire 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% [http://www.forskningsdatabasen.dk/cgi-bin/egwddf2/6969/screen.tcl/host=ddfcat&host=ddf&gattr1=parseOp&v=1&fe=10&e11=indoor&f11=all&l11=and&s1=sortkey&page=28&name=show_record&norec=1&ppage=30&lposddfcat=7&lposddf=24&service=ddf%32&context1=b&lang=eng]).The 44 kWh/m² resulted from:

*[[Electricity]] – 18 kWh/m²

*[[Space heating]] – 14 kWh/m²

Line 48:

*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 [[solar cell|photovoltaics]].

The buildings were constructed to be [[airtight]], be [[superinsulation|superinsulated]] to roughly double normal standards, and to minimise [[thermal bridge]]s. [[Masonry]] and several [[timber frame]]d methods were represented, alongas withwell aas newly noveldesigned [[steel]] strengthened [[polystyrene]] block walls were used. The Berlin "Zero Heating Energy House" included a 20m³ (700 cubic feet){{conv|20|m3}} [[Seasonal thermal energy storage|seasonal thermal store]].[http://wire.ises.org/wire/doclibs/EuroSun96.nsf/id/F7DE064B758101BDC12565E6003737C3/$File/paper.pdf]

The homes in the programme were:

*Care was needed to design out summer overheating

*Simple installations and systems were easier for the residents to understand
