This document discusses zero energy buildings (ZEBs). It defines different types of ZEBs, including net zero site energy, net zero source energy, and net zero energy costs. It explains that ZEBs reduce energy consumption and greenhouse gas emissions, decrease dependence on fossil fuels, lower climate change impacts, and protect the environment for future generations. Key aspects that make a building ZEB include site selection, passive solar design, high-performance building envelopes, low energy consumption, and active energy systems like solar panels. Various strategies are presented, such as daylighting, natural ventilation, radiant heating/cooling, and thermal mass. Examples of real ZEBs from the NREL and Singapore are also highlighted.

I’d put my money on the Sun
and Solar Energy,
what a source of Power!
I hope we don’t have to wait
until oil and coal run out,
before we tackle that.
