Ground Occupation Bonus
Topic of the practice
Spatial planning bonus for small scae renewables in buildings
Good Practice Information
The Ground Occupation Coefficient bonus (GOC bonus) is an exemption from planning rules which allows a builder to construct a larger floor area building than would noramlly be allowed if the building achives higher than currently standard energy efficiency and/or includes renewable energy. The GOC bonus is an incentive to build high energy performance buildings and to use RES. The local municipalities decide whether or not to run the GOC Bonus in their local planning rules. The floor area bonus can vary from 5 to 20%, according to the following energy performance conditions :
■ HPE = -20% from the 2005 Thermal Rules
■ HPE EnR = -20% from the 2005 Thermal Rules and use of RES or/and Heat Pumps
■ THPE = -30% from the 2005 Thermal Rules
■ THPE EnR = -30% 2005 from the Thermal Rules and use of RES or/and Heat Pumps
■ BBC = Limited primary consumption 50 kWh/m2.y (depends on location/altitude)
The local municipalities decide the level of GOC increasing for each energy performance level. The energy performance level must be guaranteed by certification (new building) or professionnal auditing (for extensions of existing building). Under energy performance conditions, a building can get one or two more levels. The following examples show the possibil-ity of extension over the running planning rules if :
For a new residential building, there is a very good insulation and solar thermal panels.
For an existing building, the extension is possible if insulation is improved and/or solar panels are used to produce hot water, heating or electricity.
Evidence of success
It is considered as a good practice because when the local municipalities decide to run the GOC Bonus they incentivise developers to create buildings of a higher energy efficiency (and/or use of renewables) .
