Sustainable Building Services

Renewable Energy Consultants

Once you have realised an efficient insulated fabric and efficient mechanical and electrical design, you may want renewables to reduce consumption further and possibly even generate energy to export. 

We work across the building’s lifecycle, from concept to construction. Correctly sizing thermal and electrical loads, storage and realistic yields and savings is essential for successful building service projects.

Initial Assessment & Feasibility

Its a bewildering choice and the deployment of these technologies have been mixed. Suppliers can promote their preferred solution, which is usually viable, but may no be the best one for your building.  Once a set of design calculations has been done we can find the optimum balance between performance and upfront cost based on independent saving calculations.

We then can help with the real life performance and cost due to the large number of renewable projects we have done over the last 20 years. 

Detailed Design & Specification

Often overlooked is the value of good design – the technology itself can be very expensive so trying to minima the actual load needed can save a lot of money at the build stage. The contractor’s may need detailed specifications for installation as they may not be familiar with some of the technologies involved.  

We can also handle the technical aspects of the building warrant or planning process.

Remediation and Commissioning Checks

Your existing project may not be integrated to the whole building needs and/or you may want independent verification of the setup and performance in-situ.

How We
Can Help

Traditionally heating/services were a standard work package handled by the trades and architects but buildings, regulations and the needs of the client have become more complex over time, and rightly so. Heating is integral to the comfort and well-being of your home/work and is only now been given proper consideration in the build. Also, often it can have the largest impact on operating cost for you in terms of bills and carbon impact over the long-term. In addition, there are a multitude of options available with renewable technologies in a fast-changing market. There can be a considerable cost benefit to have input from specialist independent building service engineers at several stages.
