BER Assessment- A Commercial Viewpoint

DEAP software

As we already know, the owner or developer of a new establishment hires a registered BER assessor, to carry out an assessment based on the plans and specifications of the building. The assessors follow a standardized procedure based on a pre approved rating scale and a standard code. A Commercial BER Certificate is a label similar to the one used for non-commercial buildings. The label in this case is of a 21 point scale, which indicates the energy rating of a property, an A rating being the most efficient and rating G, being the least.

Commercial BER Assessment

The BER assessment of any commercial establishment differs greatly from any non-commercial or residential BER. Commercial BER Assessment is divided into three categories i.e. three four and five. Commercial Building Energy Rating Assessment Dublin, gives us a brief understanding of the various categories, which are described as below:

  • The most common commercial buildings fall under Category 4 and covers all new and old buildings are it offices, supermarkets or even warehouses.
  • Buildings with lesser complexities having simple natural ventilation belong to Category 3 type of commercial buildings. Example – Doctor’s chamber or surgery.
  • All factories fall under Category 5 building types, which are the most complex.

The Methodology Used

Non Domestic Energy Assessment ProcedureThe BER and the advisory report for new and already existing buildings are generated by the Non Domestic Energy Assessment Procedure ( NEAP ). This methodology calculates the energy consumption and the CO2 emissions associated with any standardized commercial building. The method and assessment take into account:

  • The age structure and the geometry of the building
  • The heating system that has been used in the building
  • The ventilation used in the building
  • The thickness of the insulation materials used and its type
  • The kind of lighting used, and finally
  • The type of renewable technologies used

After the assessment is done, the survey findings are imputed into the DEAP software, by a Energy Assessor Dublin . The data are then uploaded and the BER certificate is generated by the Advisory report, which gives recommendations for improvements. Thus a commercial BER certificate helps to decrease the energy cost involved thereby increasing the energy rating of the building!
