If you are building, selling or letting a non-domestic building, before practical completion can be granted the new occupier or owner must be supplied with an Energy Performance Certificate (EPC) which grades the building's energy efficiency. In this programme we visit the new flagship John Lewis Store in Stratford, to see how a non-domestic EPC survey is undertaken and what factors are key in influencing the final EPC grade.

Key learning:

  • An explanation of when an EPC is needed and what it measures
  • The importance of zoning and the role of computer modelling
  • The impact efficient lighting can have on the final EPC grade
  • The relationship between BREEAM and EPCs
  • The impact of the newly enacted Energy Performance of Buildings Regulations 2011
