Energy Performance Certificates ( EPC's )are needed when a building is sold or rented, newly constructed or for application for grants and finance ( Feed in Tariff, Green deal)
Various software is used to produce the Certificates. These vary in complexity.
Domestic Energy Certificate- the most basic is for existing houses. The Domestic Energy Assessor ( DEA ) will survey the whole house to establish the age, size, heating, construction, glazing, lighting and insulation of the original house and its extensions. The evidence for this is photographed as the DEA surveys the house, the data collected is then entered into Reduced Data Standard Assessment Procedure ( RDSAP ). For an average house the survey takes about an hour. The actual data entry can be entered on site but is often entered back at the assessors office allowing careful assessment of the information gathered.
The PDF of the EPC is normally sent through after a few days.
SAPs EPC- Any house built or being built since April 2008 will need to have an assessment based on the SAPs software a standard RDSAP EPC will not be valid.
This is more complex and takes longer to gather data either from plans if the building is at the construction stage or from a survey of the built building.
Non-Domestic ( Commercial ) EPC using SBEM ( Simplified Building Energy Model )and DSM ( Dynamic Simulation Model ) Software. These are for Commercial Buildings and are more complex still. Each room is assessed and may even be entered separately. there are 3 grades of Commercial EPC:
Grade 3 small Units with simple heating and Cooling systems
Grade 4 Units which have a more complex zoning,heating, cooling, ventilation system. or newly constructed Units
Grade 5 Very unusual, normally hi-tech buildings with complex systems in place. Only DSM is used for these.
