#031 - SPOT THE DIFFERENCE


Please help Mr D. Tail to spot the differences within a Passive House and Passive Solar House.

Passive House and Passive Solar House are design standards for energy use in all building type. The design process it helps to reduce the buildings ecological footprint which is sometime we should be worry about:

“In 2012, direct buildings emissions (mainly from the use of gas for heating) accounted for 37% of UK greenhouse gas emissions (91 MtCO2). Buildings also were responsible for 67% of electricity consumption and related (i.e. indirect) emissions.” From www.theccc.org.uk

The Passive House relay on energy conservation through super-insulation, the heat losses of the building are reduced so much that it hardly needs any heating at all. However it involves the use of mechanical and electrical devices.

The Passive Solar House instead relay to the sum. It distributes solar energy in the form of heat in the winter and reject solar heat in the summer, this system virtually does not involve the use of mechanical and electrical devices.

Both design standards are effective. The Passive Solar House design is performing better in sunnier climates white the Passive House design is performing better on colder climate.

The systems in reality are not perfect and without problem but they are a huge step forward the reduction of greenhouse gas emissions.
