Sustainability is at the heart of everything calfordseaden does. We are committed to minimising both the adverse environmental impacts of all schemes we deliver and in the activities we undertake.

Our dedicated team of sustainability advisors include Code for Sustainable Homes (CSH), HQI assessors, Low Carbon consultants and BREEAM: New Build, (NC), Refurbishment and Fit Out (RFO), non-domestic schemes (including commercial, healthcare, multi-residential and education). The team offers standalone services and works collaboratively with our other professional disciplines, to ensure our clients always receive the best possible sustainability advice.

We are passionate about delivering sustainable communities, be it a new build or raising the environmental standard of existing developments. Now, more than ever, there is a need to take a more strategic look at existing stock to maximise the benefit of the building fabric, whilst also looking at the introduction of cost saving and low energy technologies allied with educating users.

We continually strive to achieve sustainable advantages for our clients. By measuring the effectiveness of the low carbon technology solutions introduced on our schemes, we have measured the energy benefits against costs and developed simple schedules of the most effective carbon saving measures on a range of property types.

We consider all aspects of sustainability, including social and environmental impacts, waste minimisation and energy efficiency. In helping to influence the supply chain to put greater emphasis on sustainability specifications, we assist organisations to improve quality and reduce costs while having a positive long-lasting impact.

Creating a better quality of life for everyone.
