How Building Regulations compliance is achieved.

The reference documents are Building Regulations part L and Technical Guidance Document TGD L 2006 Edition

The Carbon Dioxide Emission Rate (CDER) associated with the energy use for space heating, water heating, ventilation and lighting for an actual dwelling, should be less than the Maximum Permitted CO2 Emission Rate (MP CDER) for a reference dwelling.

The Reference dwelling is specified in Appendix C of TGD L

Compliance demonstrated using national methodology DEAP. The carbon dioxide emission rate is calculated using the DEAP method for a reference dwelling of the same size and shape as the dwelling to be assessed, but with the relevant characteristic specified in APPENDIX  C of the Technical Guidance Document Part L. The result of this calculation is the MPCDER for the actual dwelling.

The CDER calculated for the dwelling should be less than the Maximum Permitted CO2 Emission Rate (MPCDER) .

The CDER and MPCDER are expressed in terms of kilograms of CO2 per square metre floor area per year (kg CO2 /m2 /annum).
