Passive houses provide a comfortable indoor climate at any time of year without using conventional heating. They need only 10% of energy that a standard new building uses - good for the environment and the home-owner.
Instead of traditional mechanical heating and cooling, passive houses use smart, time-tested heating and cooling methods like natural ventilation, solar heat gain and efficient insulation.
Passive housing is effective for any building that uses energy - residential housing, offices, schools, supermarkets and factories.
In the UK, the Government has pledged that all new build houses will be 'Zero Carbon' rated by 2016 - a target that passive housing could help achieve.
