Green Refurbishments
 
When carrying out any refurbishments we always try to follow 'The Standard Assessment Procedure', or 'SAP', which is the UK government adopted methodology for calculating the energy performance of dwellings. It is used to demonstrate compliance with building regulations, and to provide energy performance ratings. 'AMEE' provides a platform for the complete SAP methodology.
 
  • Dwelling size (floor area, number of floors, storey heights, etc.)
  • Materials used for the construction of the dwelling
  • Thermal insulation properties of the construction material
  • Ventilation characteristics of the dwelling
  • Efficiency and control of the heating system(s)
  • Solar gains through openings in the dwelling
  • Fuels used for heating, ventillation and lighting
  • Renewable energy technologies

SAP methodology uses the Building Research Establishment Domestic Energy Model (BREDEM) to integrate these data and generate the following energy performance ratings:

  • Energy Consumption Rating: energy consumption per unit floor area
  • Energy Cost Rating (SAP rating): a value between 1-100 representing the cost of space heating, ventilation and lighting, minus any savings associated with energy generation technologies, standardised by floor area. Higher values indicate lower running costs
  • Environmental Impact Rating (EI): a value between 1-100 representing the the annual CO2 emissions associated with space heating, ventilation and lighting, minus any savings associated with energy generation technologies, standardised by floor area. Higher values indicate higher standards
  • Dwelling CO2 Emissions Rate (DER): CO2 emissions per unit floor area


These ratings are independent of dwelling occupancy, individual heating preferences and the energy consumption of non-heating appliances.
