Design + Construction
We offer practical solutions for energy efficiency and building performance in a language you can understand. We work with clients to manage the sustainability elements of projects from start to finish, ensuring all performance targets are met on time and on budget.
​
​​Recent updates to Building Regulations have introduced provisions to address overheating, particularly important in densely built-up areas and with the increasing frequency and intensity of heatwaves.
This may involve specifying measures such as increased ventilation, shading devices, and thermal mass.
​
The Part O guidance has been based on the CIBSE TM59 methodology with a few variations.​​
​
Part O Overheating + TM59
We carry out assessments using dynamic simulation modelling for individual houses and multi-residential apartment blocks.​​​​​​​​
​
Where the development is mixed use we can combine this with other overheating assessments such as CIBSE TM52 or BB101 to ensure all spaces are not at risk of overheating during the summer months.
​
CIBSE TM52
​
CIBSE TM52 addresses the risk of overheating in non-domestic buildings and can help to predict early on where designs may require additional shading or ventilation.
​
Meeting thermal comfort criteria can be a pre-requisite for some environmental building standards such as BREEAM or LEED and can be particularly important for buildings with vulnerable occupants such as care homes.

BB101 Designing for Schools
​
​There are two distinct stages to carrying out a Part L calculation; the DESIGN stage and the AS BUILT stage.
​
The early design calculations may be carried out during the planning phase and utilising DSM, the energy calculations can be run in conjunction with with other thermal modelling assessments such as overheating, daylighting etc offering time and cost savings. It is important to note though that any early design modelling carried out up to RIBA stage 3 will be based on high level data and assumptions and should always be carried out again prior to construction.
​
Detailed design calculations can then be carried out at RIBA stage 4 and can be checked and updated throughout the construction should any design changes be made or value engineering be carried out.
​
Once construction has been completed and air testing carried out, the as built version of the model can be created to create the BRUKL document and Energy Performance Certificate (EPC).
​​
SAP (Standard Assessment Procedure) calculations are the domestic equivalent used to assess the energy performance of dwellings.
​
The process is similar to that carried out for SBEM and will ultimately produce the EPC on completion.
