What is the energy performance of buildings (EPG)?
The energy performance of buildings (EPG) is a new, overarching assay method for the energy performance of buildings. The EPG applies to both homes and utility buildings for:
- accommodation buildings
New standards to meet new developments
The Dutch Standardization Institute (NEN), the new standard published on April 15, 2011. The EPG has it received the number NEN 7120. Also, the NEN yet published two other new standards, both associated with the EPG. These are:
- the energy performance measures at area level (EMG) (NVN 7125);
- the ventilation standard (BS 8088-1).
With the new standards Netherlands meets the requirements of the revised European Energy Performance of Buildings Directive (EPBD).
Effective Date new standards
From 1 July 2012 the EPG is (NEN 7120) as a new standard for determining the energy performance of new buildings. With the new energy performance, the latest techniques in the areas of energy efficient building properly assessed. The introduction of the EPG also allows to vote. Determining methods for new and existing buildings on each other.
Norm and software were available beginning in April 2012 and the market can get to work to gain experience with the EPG. In June 2012, the amended scheme and effect decision published. Until July 1, 2012 the existing energy performance standards for homes (NEN 5128) and utility buildings (NEN 2916) apply.
Only for new construction
The EPG is initially only for new construction. In time, the EPG also apply to existing buildings. Yet remain above the current ISSO publications apply.
Difference EPG and EPC
The EPG is different from the Energy Performance Coefficient (EPC). The EPG shows the determination method, the EPC indicates the level to which the building must meet minimum. The EPC is calculated using the EPG.
Of course, we make sure that we can make. EPG your calculations on time.
EPG first only for new construction, but we’re already on.
The EPG is only for the new building. Later, the EPG will also apply to existing buildings.
We use the EPG now in renovation projects. This is a kind of “custom”.
