What is the Great Importance of SAP Calculations For Extensions?

SAP Calculations are a part of government’s plan to reduce carbon emissions. These calculations are used to measure and assess the energy efficiency of houses. It is usually seen that openings and glazing's lose more heat than walls and roofs. This is the reason why the building regs have set a limit. By overcompensating or upgrading the various elements of your house, you can eliminate the negative impact of large expanses. 

Many homeowners often ask if all the house extensions need SAP calculations or is there any rule that large extensions need a SAP calculation. Well, the answer to all these questions is no. It all depends on the amount of glazing. In ideal circumstances, the glazing area of the extension should not be more than quarter of the floor area including the amount of glazing. 

How is SAP Measured?

For setting a SAP rating for home, a registered and accredited assessor will visit your home. Now this assessor could be your architect or a third party assessor. With the help of SAP ratings, you can compare the energy performance of different homes against each other. With the help of SAP, you can measure how much energy will be used, how much will be gained or lost. It is worth nothing that SAP ratings would not include the energy used for running the appliances or cooking. This could also mean that homes can be measured and compared accurately. The SAP ratings are recorded on a scale from 1 to 100 where 100 represents zero energy cost. The higher the SAP ratings, the more energy efficient the home is. With the help of SAP calculation, you can use a large number of inputs for the calculations. 

That was some useful information how SAP rates are calculated for extensions.
