The Building Energy Rating Certificate (BER) is part of the Energy Performance of Buildings EU Directive. The aim of the Directive is to make the energy performance of a building transparent and available to potential purchasers or tenants.
A building energy rating certificate is issued after the BER has been carried out.
Preliminary BER Certificates can be provided using a Simplified Building Energy Model which gives a quick turnaround assessment at the pre-planning stage. For complex buildings that involve atria, natural ventilation and complex building structures, we use an integrated environmental simulation which allows much a more advanced computer simulation of the building.
In all cases, the Building Energy Rating will be accompanied by a detailed report. The report identifies building improvements and investment options for the client to improve the building performance and reduce running costs.
Building computer simulation
The building is constructed within a computer programme so the energy performance can be modelled. This provides the facility for the following:
Preliminary building assessment and advice on the energy implications of the following:
- Building orientation and implications on solar gain and heat loss
- Glazing rations and implications on natural ventilation and day-lighting
- Floor depths and implications on natural ventilation
- Issue of preliminary Building Energy Rating (BER) Certificate
- Assessment of possible renewable energy solutions & associated planning information
Detailed building assessment to highlight the impact of material selection and construction details on energy consumption:
- Predicted annual energy consumption
- Assessment of material selections and product substitution and its associated impact on energy usage and compliance
- Daylight analysis and its interface with lighting control systems to minimise the use of artificial light
- Design of naturally ventilated buildings
