Energy reduction, the core of sustainable design, was inherent in our building design process long before it reached the political agenda. Our sustainable credentials are therefore built upon years of experience at the forefront of low energy, low carbon solutions for a wide range of sectors.

Our approach is holistic and collaborative, extending beyond the building services systems to the fabric and form of buildings and development sites.

Our engineers and technicians possess a unique, intimate understanding and knowledge of energy use in buildings and they have been responsible for the design of numerous BREEAM EXCELLENT schemes.

We draw upon extensive experience of sustainable and low energy schemes having completed many examples. We have a full range of modelling and simulation tools at our disposal to ensure the optimum solution for each situation and our expertise encompasses the selection and incorporation of renewable energy sources to offset energy demand and our projects have included a variety of renewable technologies.

Strategic Role

Assist clients with the development of viable sustainability guidance and policies for New Developments and Existing Estates. Monitor the Implementation of the Guidance and Policies

Our approach to sustainable design is outlined below.


Stage 1 - Passive

Get involved early in the building design process and provide advice to the architect and structural engineer on the passive means of reducing energy consumption. These include orientation, mass, layout, insulation, glazing and shading. Building modelling begins at this stage and we pursue the use of passive measures as far as is economically viable before moving to stage 2.

Stage 2 – Active

We consider the systems which will result in the least use of energy, whilst meeting the clients for the internal environment, brief and cost allowances. Modelling continues during this stage and includes predictions of the EPC rating for the building. Control systems and recovery of waste heat are a major part of the process. The stage also includes an examination of water systems and the opportunities for collection and recycling.

Stage 3 – Renewable

We consider the systems which would be suitable for incorporation in the design which would reduce the energy demands of the building or development. Measures examined will include air and water sourced heat pumps, wind turbines, solar hot water, photovoltaic’s, CHP and biomass heating. These will be considered in relation to the budget, client and planning requirements. Options are presented on a whole life basis to enable final selection by the team.

Stage 4 – Waste and Recycling

General discussions have been held with a number of the suppliers we use on waste and recycling. During the selection and specification process project specific discussion take place to on manufacture source, packaging, dismantling and recycling.

Specifications will include statements on source, waste and recycling requirements.
