Building Envelope Animations

We believe in an envelope-first approach to low-energy buildings.  We think a good envelope means a smaller mechanical system. We believe in good form factors, great orientation, extra insulation, low thermal bridges, excellent windows and doors, airtightness, and small + energy-efficient mechanical systems!

Mechanical Systems

Net Zero Energy and Passive buildings require heating (and sometimes cooling), ventilation and hot water systems that are highly efficient.  This section contains a series of animations that explain how a variety of mechanical systems work.  These animations should help you, your clients and / or your family understand how Zero Energy buildings operate.
