When do i need an sbem

Either way, we can help you with information or calculations. However, limits on the amount of glazing and thermal elements may make the building design tricky. A Whole building calculation method uses SBEM to provide greater design flexibility and demonstrate reasonable provision towards compliance.

Assessing building fabric and the HVAC systems heating, cooling and ventilation , hot water and fixed lighting systems to make sure they achieve reasonable overall standards of energy efficiency.

Demonstrating appropriate passive control measures to limit solar gains during summer months, in order to reduce the need for air conditioning systems. Making sure there are the necessary provisions for enabling the energy efficient operation of the building put in place. These documents are concerned with the conservation of fuel and power. How Are The Calculations Done? View all services. Since , Energist have been working by your side to reduce workloads and risk, cutting the complexity of regulation compliance.

New-build dwellings attached to an existing building are also still treated as new build and must comply with L1A. Compliance with Building Regulations L1B for dwellings and L2B for non-dwellings for work on other existing buildings just requires meeting minimum standards for opening areas, fabric and services. This would need to be shown with a CO 2 calculation through the relevant tool. Holiday accommodation does not need an EPC if it is rented out for less than 4 months a year or is let under a licence to occupy.

For more information on EPCs, see this guide for dwellings and this guide for non-dwellings.
