FURTHER DETAILS
The minimum fabric standards set out in Table 0.a were expected to be implemented in all units to comply with Fabric Energy Efficiency Standards targets and Target Emissions Rates in Building Regulations Approved Document Part L1A 2013.
Table 0.a Building Fabric Standards and Zero Carbon Targets (Zero Carbon Hub 2011)
The Land East of Will Hall Farm Development requires a minimum energy demand reduction of approximately 173,091 kWh/year to achieve the 10% energy demand saving from decentralised and renewable or low carbon energy sources.
It was proposed to deliver this by roof mounted Solar PV tiles which offer good electricity generation whilst having little or no visual impact.
Where the installation of solar PV is not feasible as set out above, ground source heating was evaluated for detached homes with sufficient space.
