What Are SAP Calculations? Domestic SAP Calculations help you calculate how much energy your home is likely to use, as well as the level of CO2 emissions it will produce. However confusing they might appear, SAP Calculations are a core element in the design of any residential scheme, and an essential part of existing Building Regulations. Under Part L of the building and planning regulations in the UK, it is mandatory for new homes to have been through an SAP Assessment, and as a result of this, most developers have a working knowledge of their content.
However, first time builders, developers and self-builders are sometimes challenged by the process of SAP Calculations in the building and planning phase.
The role of SAP calculations for buildings is threefold: 1. To calculate the energy-related costs of a dwelling. The resulting figure is called a SAP Assessment Rating. 2. To evidence compliance with building regulations (Part L) 3. To generate data required to put together an Energy Performance Certificate (EPC)
A slightly different SAP assessment may also be required when building an extension or carrying out a conversion. If you are building in Scotland, bear in mind that different requirements apply, so please make additional checks.
