Ecological features
This is Redevco UK’s first green wall and roof. In addition to the ecological benefits it is a physical symbol of sustainability and greening of the UK portfolio and had been popular in the UK office. This was the largest single cost item at £27,500 however it was also the greatest single contributor to the improved score giving an additional 4.7%.
Energy
- The second largest cost item was the replacement of all common parts lighting with LED’s. We expect an annual energy saving of £5,900, 42,200 kWh and 21,966 kg of CO2.
- The payback period is five years, however some of the savings will benefit our tenants.
- Other improvements to the energy score include the calculation of energy efficiency ratings for boilers, chillers and supplying additional evidence around HVAC system.
- The energy score increased by 4.5%
Sustainability
- This is the UK’s first significant BREEAM improvement project.
- This asset achieved a BREEAM In-Use Very Good Rating, the highest achieved so far for Redevco UK.

Learnings
- Start planning early: The green wall took five months and six different contractors/consultants.
- Get an up to date Gap Analysis: BRE update their criteria regularly and so our 2014 Action Plan was not reliable to estimate costs and improvements.
- Water: It would be good to have included improvements and gain credits for water conservation.
