The brief
- We were instructed to complete SAP Assessments on two plots in Barnsley
- These consisted of L1A Design and As-Built SAP Calculations, which include an EPC
- Water Efficiency Calculations were also completed for these properties
The process
-
Compliance was achieved via the following recommendations from our Assessors:
-
Low U-Values
-
Efficient Heating Systems
-
Low Air Permeability Targets (≤ 5)
The results
Plot 1 Target Emission Rate (TER)
Plot 2 Target Emission Rate (TER)
Plot 1 Target Fabric Energy Efficiency (TFEE)
Plot 2 Target Fabric Energy Efficiency (TFEE)
Plot 1 Dwelling Emission Rate (DER)
Plot 2 Dwelling Emission Rate (DER)
Plot 1 Dwelling Fabric Energy Efficiency (DFEE)
Plot 2 Dwelling Fabric Energy Efficiency (DFEE)
-
Compliant
-
The DER/DFEE achieved well below the requirement in order to meet the TER/TFEE
-
The predicted EPC scored an Energy Rating of B, meaning the building would be highly energy efficient
-
The Water Usage Calculations achieved were 109.65 Litres per person per day, the Target being ≤ 110L
