What Building Regs Say…

Approved document LIA 2006 requires that all new dwellings have an acceptable CO2 emmisions rate.This is known as the Dwelling Carbon Dioxide Emissions Rate or DER, this is the actual leakage of the building. The Target Carbon Dioxide Emisions rate or TER is determend by the designer using a SAP calculation, and must be higher than the DER test result.
