Site layout

Energy efficiency of a building depends on the sitting of the building by

Using southern orientation of buildings for passive solar heating.

Including shading for summer months to prevent overheating

Avoiding placing buildings on shady places like northern slopes or the north side of dense forests or high buildings close to them.

Considering compactness of the structure: tall buildings compared to row houses allow for approx. 10% less heating energy consumption

Utilising roof areas for active solar use (in which optimum is solar panels facing south)

Avoiding over-clouding of the building of its neighboring houses for more than 50% of the south-facing facade on December 21 at 14:00.

Finding an optimum site for the building

Building permits

Do the local regulations allow for

Stepping outside the building lines for the size of the "extra insulation" needed for building passive houses?

horizontally and vertically (in height) Change in orientation for optimizing the

angles and best utilization of the sun?

Are there any privileges for building passive houses when it comes to getting building permits (e.g. faster response or easier search for subsidies)?

Building form and function

Since heat is lost through transmission through the building envelope a compact building form gives a better energy performance due to less surface area.Service zones (kitchen, bathrooms, and toilets) should preferably be concentrated and positioned in the north area of the building as they need less window area.

The building envelope including building services installations should be carefully considered to achieve a good air tightness.

Sector

Comfort – radiation temperature of different surfaces

Cold component surfaces in poorly insulated houses cause unbalanced surface radiation temperatures.
