Building Services Engineering

Using advanced building performance simulation, we compare different design options and identify best solutions, ensuring your designs meet performance targets at the early design stages.

Our models provide fully-integrated performance analysis including energy and comfort, HVAC, daylighting, cost, design optimisation, CFD, LEED credits, and reports complying with several national building regulations and certification standards.

​

U-Values measure the rate of heat loss through a structure, such as a wall, and plays an integral part in SAP and new build SBEM calculations.
We provide U-Value calculations in-line with the latest industry standards.

Overheating in homes is projected to increase with the effect of climate change, presenting a risk to health, wellbeing, productivity and in worst cases can lead to mortality in the most vulnerable. The Department for Levelling Up, Housing and Communities (DLUHC) has introduced a new Building Regulation (Part O) making it a legal requirement for developers to provide Building Control Bodies with evidence to show they have reduced the risk of overheating. 
We provide overheating risk assessments through the detailed method of Dynamic Thermal Modelling, showing compliance with Part O.

With the option for using Accredited Construction Details being removed for new buildings built to the new Building Regulations Part L 2021 standards, having accurately modelled psi-values would help greatly in achieving compliance with building regulations. 

Psi-values calculate a building’s overall heat loss at a junction (also referred to as non-repeating thermal bridges). In order to help achieve building regulation compliance, we undertake 2D & 3D thermal bridging calculations for junctions to model your own bespoke psi-values instead of using default values.
