9 Greyfriars Road Shortlisted for Building Awards Sustainability Project of the Year

We are proud and extremely pleased to announce that 9 Greyfriars Road in Reading has been shortlisted for the ‘Sustainability Project of the Year’ at the 2017 Building Awards, a scheme that Greengage were the BREEAM Assessors, BREEAM AP and Sustainability Consultant for.

The scheme at 9 Greyfriars Road involved the full refurbishment of a 1980s building in Reading town centre including a new full height glazing system and Mechanical & Electrical throughout. It is the first office building outside of London to achieve BREEAM ‘Outstanding’ and an EPC A rating, providing occupiers with excellent energy efficiency and low carbon credentials. This highly sustainable building has lower operating costs and has been designed to incorporate features that enhance occupier health, wellbeing and productivity.

The project team managed to increase the BREEAM rating from ‘Excellent’ at design stage, to ‘Outstanding’ by the end of the construction stage, an achievement that goes very much against the trend of green buildings having a performance gap between their design and construction stages.

Key factors to achieve ‘Outstanding’ included:

  • The installation of a high efficiency Air Source Heat Pump (ASHP) resulting in a 20% reduction in CO2 emissions, the award of the first of three BREEAM Innovation credits and significantly lower estimated energy costs when compared with other benchmark buildings.

  • The installation of water efficient sanitaryware, flow restrictors, PIR sensors and a leak detection system to minimise water use and wastage from the building. These installations resulted in an estimated average water consumption of 5.3m3/person/year, which is less than half that of the typical figure for offices.
  • Retaining 99% of the existing structure and recycling over 92% of the construction waste produced on-site. This high recycling rate earned the project the second of the three BREEAM Innovation credits awarded to this scheme.
  • New full height glazing was installed which maximised the daylight levels within the building resulting in an average daylighting factor greater than 4%, which exceeds the BRE Innovation credit level requirement of 3%. The high level of natural light is designed to support the circadian rhythm of employees, increasing alertness and decreasing fatigue whilst also contributing to reduced energy usage through the need for less artificial light.

Rob Miller who leads the Sustainability team at Greengage said: “We worked hard to deliver a highly sustainable development that is also a huge commercial success and asset to our client McKay Securities.”
