Building Physics & Energy Modelling

Building Physics & Energy Modelling

We provide building physics and energy modelling services to demonstrate compliance with the Building Regulations, help you better understand the way your buildings perform as whole systems and identify cost-effective opportunities for improvement.

Building physics is the application of the principles of physics to improve a building's operational performance for reduced energy consumption, environmental impact and improved indoor environmental quality.

Building energy modelling is a virtual means of emulating a building's energy behaviour, whether for demonstrating compliance with Building Regulations, investigating impacts of design solutions, or for early testing of design solutions to ensure robust outcomes.

Our building physics and energy modelling services

We offer integrated building physics and energy modelling services spanning a range of building projects. On new-builds, we work with architects, developers and building owners to push building energy performance to the highest feasible levels, leveraging on ‘passive’ design strategies starting from site assessments - for example: climatic conditions, optimum orientation, and solar gains.

In relation to existing buildings, we assess the energy performance of specific buildings, identifying and evaluating the viability of bespoke energy-efficient measures, or work on large building portfolios via archetypal reference buildings.

Our unique expertise allows us to address the gap between design and ‘as-built’ performance so that the building is actually delivering 'what it says on the tin'.

With an in-depth knowledge of Part L Approved Documents and energy efficiency legislation, our experts include Domestic Energy Assessors accredited to undertake regulation compliance checks, and Energy Specialists with broad experience in evaluating the implications of Energy Performance Certificates (EPCs) for new and existing buildings.

We provide consultancy around the most cost-optimal ways of adhering to the Minimum Energy Efficiency Standards that will make F and G EPC-rated properties illegal for private rent from April 2018.

Our services also include detailed advice on Passivhaus schemes, utilising the Passivhaus Institute-approved PHPP software.

In addition to using standard energy modelling tools, we also apply advanced computer simulation to dynamically model complex buildings and systems, and bring insights into how to optimise operational performance.

Whether new-build, existing or retrofit, we use dynamic simulation modelling (DSM) such as IES Virtual Environment and EnergyPlus to solve real-world problems related to comfort and liveability (for example: overheating diagnosis, ventilation strategies and indoor air quality) by concentrating on the interactions between variables such as operative temperature, solar gains, daylighting and views.
