Project Overview

Remodelling of a school to deliver Low Carbon teaching space, including passive stack ventilation, and optimised natural lighting combined with high efficiency artificial lighting with automatic dimming controls - Awarded a BREEAM Very Good rating.

Worcester County Council are recognised as a leading Local Authority on sustainability and Low Carbon Strategy. Briar have been privileged to provide Low Carbon M&E Design and project management to WCC for over six years, developing schools, sports centres and general extensions/services design.


Worcester County Council and the Cookley Sebright School wished to create new flexible, high quality teaching facilities through the remodelling of the existing school site. This included the demolition of an existing antiquated swimming pool/changing facility and the construction of six standalone key stage 1&2 classrooms (Phase 1), with the further addition of two nursery and reception classrooms plus a new main school entrance facility (Phase 2).

Keen to minimise the long-term environmental impact and to support the achievement of a ‘very good’ BREEAM rating, the Council required the new facilities to incorporate cost effective, practical low carbon M&E design to minimise long-term energy consumption, carbon emissions and running costs. This included the integration of high efficiency lighting with automatic dimming controls, gas-fired condensing heating boilers and a passive stack natural ventilation system, all controlled via an advanced BMS accessible by the Energy Manager at County Hall.

Briar were appointed as a result of our expertise and experience in the design of low carbon M&E services within the Education Sector and we are approved on the Worcestershire County Council M&E Framework.

The project was delivered in association with Quattro Design Architects.
