SAP vs SBEM: What’s the Difference and Which One Do You Need?

When it comes to building compliance and meeting energy performance standards, understanding the difference between SAP and SBEM calculations is key. There’s no denying the importance of assessing how energy efficient a building is, but SAP and SBEM can’t be used interchangeably. Though similar assessments, SAP and SBEM look at different building types and purposes.

To ensure that your building project is being assessed correctly, you need to know the difference between SAP vs SBEM. Choosing the right one from the start can save time, money and confusion during the design, building and approval process. Below, we’ve taken a look at SAP vs SBEM and which one is right for you.

TM44 Inspections – Air Conditioning Systems Compliance

The UK may not be the warmest or sunniest place to live, but businesses and commercial buildings still rely heavily on air conditioning to maintain comfortable and productive environments. But, using air conditioning isn’t simply a case of turning it on, enjoying a perfectly temperature controlled room, and thinking no more of it. Operating an air conditioning system comes with responsibilities, including compliance with regulatory standards. This is where TM44 inspections come in.

What is a TM44 Inspection?

A TM44 inspection is an air conditioning system assessment, and it’s required for all systems with an effective rated output of more than 12kW. The term ‘TM44’ refers to the industry accepted guidance for the energy efficiency of air conditioning systems, as set out by the Energy Performance of Buildings Directive (EPBD), which is why they’re often simply referred to as TM44 inspections. These inspections are designed to ensure air conditioning systems operate efficiently, whilst minimising environmental impact and energy use.

The inspections should be carried out by a professional energy assessor every five years, starting just before the system reaches five years of age, and then every five years after that. To ensure TM44 inspections stay up to date and don’t lapse, it’s best to arrange them just before the five year mark rolls around.
