for high performance buildings

The Earth Rangers Centre uses earth tubes and a double foundation wall. The energy recovery in winter and summer is sufficient to temper the air about 5º C on average and up to 10º C on cold days.

It has become increasingly common to provide heat recovery on ventilation systems in buildings. In fact, it is difficult to achieve the minimum energy performance requirements for a LEED or other high performance building without it. (more…)

Building owners and designers wanting to reduce the greenhouse gas emissions and energy use of their buildings are confronted by an array of technologies for heating and cooling, all claiming superior performance and even promising guaranteed LEED credits. (more…)

Site placement, details and modest technologies deliver bright, energy-efficient interior
