CIBSE Steady State Calculations

The environmental performance of a building is dependent on a correctly selected and operated HVAC system.

Thermal modelling and simulation can be used by design teams to accurately predict heat losses and heat gains. Heat is lost from a building in two ways – either by transmission through the building fabric (fabric losses determined by U-values), or by air infiltration and ventilation.Steady State Calculations

The fabric of modern buildings, together with improved levels of airtightness means that many commercial heating systems are incorrectly sized. This can lead to increased emissions, higher capital costs and ineffective operational performance.

Advanced simulation techniques allow us to specify modular heating systems which allow higher efficiencies and part load operation with separately  pumped boilers (for example) as load demands.

CIBSE Guidance

We undertake checks that follow CIBSE procedures, giving heat losses equivalent to those in their steady state methodology (CIBSE Guide A 2015).

If mechanical cooling is present, heat gains can also be calculated in line with CIBSE steady cyclic methodology.

We work with M&E teams, architects and designers on many commercial and public buildings across the UK. We help them to not only meet their planning and compliance obligations, but to deliver buildings which are going to perform long into the future.

"THANK YOU and everyone at Build Energy so much for all the work you have undertaken free of charge to help make the Devizes build possible, that is so generous of you.....it is a real achievement, firstly in just managing to finish all the work in time for the official opening deadline but also in what has been created there.....we simply couldn’t have achieved all we have without the support of businesses like yours."
