building dynamic ENVIRONMENTAL

and Energy SIMULATION Consultancy with analysis

Provided throughout the UK AND WORLDWIDE


Commercial and Residential Energy Efficiency Consultant in the UK
At F A Vaughan, we empower architects, developers, and building owners across the UK to create high-performance, sustainable structures. As leading residential and commercial energy efficiency consultants, we specialise in developing practical passive solutions for environmental control across a diverse range of building types. From stadiums to residential complexes, our projects encompass everything from heat analysis to bespoke system energy and building performance evaluations.


Using state-of-the-art software including Thermal Analysis Software (TAS), we create 3D models of buildings which allows us to identify the constructions, heating ventilation, and air conditioning HVAC systems needed for the project. After this, we then compare these systems against winter and summer weather data to identify the environmental performance characteristics of the building.

Corridor Overheating

We are able to gain an understanding of the temperatures and natural ventilation rates in the summer months from the Dynamic Simulation Modelling (DSM) data.


Upon analysing the data produced from the Dynamic Simulation Modelling, we are able to show hourly gains and HVAC room loads.


After simulating the energy performance of a building and the systems throughout the course of the year and closely monitoring the day-to-day results, we then produce Energy Performance Certificates.


CFD allows us to create 3D models of an entire building to study the external air and transient pollutant concentration levels.

“integral part of the design team”

“We have worked with Francis Vaughan on a number of new build schemes & found him to be most helpful, working together as an integral part of the design team. We wouldn’t hesitate employing Francis on future projects.” Craig Thelwell, Director, West Lancashire Electrical & Mechanical Contractors

“Francis has always worked hard and been able to meet tight deadlines as needed and is a pleasure to work with”

“Francis was recommended to us to provide thermal modelling to evaluate overheating. We have utilised Francis’ services on a number of occasions now, to provide both CIBSE overheating analysis in residential schemes and also hybrid ventilation to classrooms to meet EFA standards and regulations. We have found Francis to have a huge amount of knowledge and experience which has been invaluable. Francis has always worked hard and been able to meet tight deadlines as needed and is a pleasure to work with. We were very pleased to receive the recommendation and are more than happy to recommend his services” John Holland – Director, D.W.Pointer & Partners Ltd

About Us

With access to the latest software, including Dynamic Simulation Modelling (DSM), we are able to provide comprehensive information on the environmental performance of a building. Here at F A Vaughan Ltd, we are experts within our field, and we pride ourselves on our ability to provide professional environmental and energy efficiency consultancy for UK clients involved in existing and proposed building projects. The quantitative results produced from the Dynamic Simulation Modelling allow design teams to judge the merits of proposed options in terms of the predicted internal environment, energy use, CO2 emissions, and related costs. Furthermore, as part of this service, we produce Level 5 Energy Performance Certificates (EPCs) for complex new and existing buildings and systems. As well as UK projects we are also able to provide our services worldwide. Established in 1991, get in touch today to discover more about our extensive range of services.
