Well then it would be like
the passive solar hot water system that does not have a defined lapse rate but does convect under a varying heat source and averages a greater temperature than the ambient local temperature (which has the GHG effect included already).
At that time, there were major advances in Building Sector technologies — in glazing materials (heat mirror and low - e coatings),
passive and active
solar energy
systems design and applications,
passive and active cooling applications, natural ventilation
systems, phase - change materials, moveable insulation, building simulation modeling programs, daylighting
systems and controls, energy management
systems, night set - back thermostats and occupancy sensors,
solar hot water heating,
solar thermal electric generation and storage, photovoltaics and advances in low - energy lighting
systems, to name just a few.
It also included pioneering use of composting toilets, a greywater and garden
system, and
passive solar water heating for domestic
hot water, radiant heat in floors & indoor forced air.
EcoDEEP Haus will be mega energy efficient by utilizing good thermal envelope strategies,
passive solar techniques, active
solar energy
systems (
hot water and PV), and possibly a small wind turbine.
