Passive Design
Definition of passive design
Energy efficient house
A passive house will keep warm for a long period of time without having to consistently put on the heating.
Concept ? The idea of a passive house is to ? Maximise heat gain and minimise heat loss
Subtopic
Function
Comfortable environment
We do not want to rely on FOSSIL fuels to heat the house
Active Heating = Oil boilers or heating systems that are not renewable.
