Energy efficient by design We focus on achieving high sustainability standards on our developments, optimising energy efficiency and generating renewable energy on site, rather than buying offsets for carbon neutrality. Our approach delivers cost savings for occupiers, well managed buildings for the people who work, shop and live in them and better assets for investors. We have delivered energy savings for occupiers of £13 million over six years, at the same time as optimising lighting, temperatures and air quality for wellbeing and efficiency. We are also improving energy modelling and piloting Soft Landings to close the gap between efficient design and performance.
