A Passive house is a building in which indoor air temperatures above the WHO recommend minimum of 18°C are maintained year round without the need for heating appliances.This makes sense, in a time of cold winters, rising electricity prices and anti-airpollution measures.

How does it work? Insulate the building well (airtight) and maximise passive heat gain. Install double glazed windows and ventilate your building. To gain heat, align it northfacing. Also appliances and the body heat of the occupants will warm it up. Install solar panels for your hotwater needs.
It all sounds simple, and it probably works, too! At a time of climate change, can we afford not to build in this way?
