The brief
- We were instructed to carry out L1A SAP Calculations on this block of flats in Croydon
- The Planning Condition required a 19% DER (Dwelling Emissions Rate) Reduction on top of baseline Part L Standards
The process
-
UKBC assisted with the specification of the Glazing, U-Values, Insulation, Heating Systems and Thermal Bridging
-
Creative solutions were required in order to achieve the 19% DER Reduction retrospectively
-
Our assessors recommended additional technologies such as flue gas heat recovery systems, waste water recovery systems and air source heat pumps in order to achieve this Reduction
THE RESULT

≤ 23.63
Target Emission Rate (TER)
≤ 55.94
Target Fabric Energy Efficiency (TFEE)
18.80
Dwelling Emission Rate (DER)
49.12
Dwelling Fabric Energy Efficiency (DFEE)
