How do the site and the building's location, orientation and shape, but also the room layout, influence the building's energy requirement?

Every building stands on a site and is influenced by the surroundings and the conditions applying on this site, such as shading by neighbouring buildings, wind loads etc.

If these aspects are taken into account in siting and orienting the building, energy can be saved on a significant scale.

Also shape and room layout are influencing factors.
