What is the requirement for HVAC system compliance for a collective housing application?

Regional compliance, local planning, and local renewable contributions need to be considered when selecting an HVAC system for a project. The London Plan is an example of an additional requirement in the Greater London Area. 

How is the compliance of an HVAC system with Part L for collective housing application assessed?

Software modelling using the government approved Standard Assessment Procedure, or SAP, measures the Dwelling Emission Rate (DER) and the Target Emission Rate (TER). TER, also known as the carbon target, is based on a notional building of the same type, size, and heating fuel. The DER is calculated from the data of the specific project and will also be affected by design factors. To achieve compliance the DER must match or be lower than TER. 

How can the Zeroth Energy System help achieve compliance?

Ambient networks are supported across the industry, including The London Plan and the Clean Growth Strategy. As the Building Regulations are expected to dramatically increase the efficiency and carbon targets in the UK, ambient loops can provide the benefits to satisfy the new compliance measures. The annual carbon reduction of a building can also be significantly reduced, helping to achieve carbon reduction targets.
