Our Work: Energy and Sustainability Statements, BREEAM Pre-Assessment, Overheating Assessment

We worked closely with the client and the design team to provide an integrated energy, overheating and sustainability (including BREEAM) strategy in a cost-effective manner, on a site presenting many challenges including noise, air quality and space restrictions. Overheating was considered in line with restrictions deriving from the site itself and the heating strategy. A holistic approach to noise, air quality and communal heating limitations was considered. We devised a strategy to ensure thermal comfort for the occupants, in accordance with the CIBSE TM52 requirements. Enhanced mechanical ventilation was utilised, combined with passive strategies including external shading, reduced glazing g-values and the use of highly reflective internal blinds.

Our Energy Statement prioritised energy efficiency measures including high efficiency fabric, combined with efficient ventilation strategies and low energy consumption lighting. An on-site energy centre, served by communal boilers and a low-NOx CHP engine, was decided to be provided to meet the high hot water demand typically associated with student accommodation. Additionally, 19kWp of PV arrays have been integrated within the design proposal. This strategy predicted a total reduction in carbon dioxide emissions of 36% over Part L (2013). We also prepared a Sustainability Statement which proposed the achievement of BREEAM ‘Very Good’ across the scheme, as well as measures for internal water efficiency, sustainable transport, sustainable urban drainage and ecological enhancement.
