SBEM Calculations are the commercial equivalent of SAP Calculations.
SBEM stands for 'Simplified Building Energy Model'. These calculations are informed by the National Calculation Methodology (NCM). Originally based on Dutch energy performance guides, SBEM calculations came into effect as part of the UK Building Regulations in 2006 and are designed to measure the energy performance of all new non-residential properties, conversions and extensions.
You need these calculations to make sure your building complies with Part L (England & Wales), Section 6 (Scotland) or Part F1 (Northern Ireland) of the most recent version of The Building Regulations. It is recommended that you get your calculations as early in your project as possible, so if your building should fail, our team can give you advise on how to improve.
In England, Your SBEM Calculations Measure Four Criteria:
• Making sure the Building Emission Rate (BER) does not exceed the Target Emission Rate (TER).
• 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.
SBEM calculations come in two formats; L2A (new builds) and 2B (extensions and conversions). The primary purpose of the calculations is to produce a BRUKL (Building Regulations Part L) report in order to create a new or updated Energy Performance Certificate (EPC).
"It was my first time using the my constructor site and I was very happy with the service. I needed an EPC for a home I was selling. It literally took a few minutes to book online and I received confirmation straight away with details etc. On the day of the appointment the assessor Alan Howard was there on time, he was friendly, polite and I received the certificate the very same day. All in all 5* for the whole service."
"We booked in for an EPC at short notice and Alan from AH Surveys thankfully managed to squeeze us in. He was friendly and professional and even sent us the completed EPC within a couple of hours from leaving our house. Would definitely recommend his services."
