Energy Modelling And Building Physics

Building physics

Often the most challenging questions we need to address during the design process are not the precise details of the building systems but the more fundamental questions about the fabric of the building and how it will behave and respond to the environment and how this affects sustainability – the building physics.

Our analysis of the building using computer energy modelling and our initial advice on such issues as shading, daylighting and thermal performance often have the greatest effect on shaping the building and ensuring a sustainable, low-energy design can be realised.

We have produced a series of one-minute YouTube videos on Building Physics which can be viewed on Method’s YouTube channel here or by visiting our Resources page here. They include Building Physics – An Introduction, Building Physics & Adaptive Thermal Comfort, Building Physics & IES Modelling, Building Physics & Natural Ventilation, Building Physics & Natural Lighting, Building Physics & Thermal Mass and Building Physics & Night Purging.

Building energy modelling and Energy Performance Certificates (EPCs)

For non-domestic buildings we use IES Dynamic Thermal Modelling software which allows us to model a building in 3D and run different simulations to establish predicted energy demand and use, lighting loads, CO2 emissions, daylight provision, overheating etc. Modelling can be used to demonstrate Building Regulations Part L compliance, BREEAM compliance or for general advice as part of our sustainability offering. Up to 19 BREEAM credits are available through energy modelling and our experience has shown that this can really help in achieving the higher benchmarks. For domestic buildings we use Stroma and Elmhurst SAP software which allows us to calculate CO2 emissions as well as Code for Sustainable Homes compliance.

An Energy Performance Certificate (EPC) is required for all new buildings and this can be produced through the thermal model and IES. We have CIBSE accredited Low Carbon Consultants as part of our team, fully qualified to produce EPCs.

IES IMPACT

IES IMPACT can be used to review project whole lifecycle costing and the materials life cycle emissions. IMPACT is a BREEAM compliant lifecycle assessment tool, and can be used to measure the environmental impact of the building. It has been developed with the BRE, so using it enables a project to achieve up to six extra BREEAM credits for lifecycle cost and materials. This can be particularly important when higher ratings are being sought or in the case of a borderline rating.
