Property and Estate Management Silver Award for JLL England 8-10 Great George Street London

The International Green Apple Environment Awards were launched in 1994 and have become one of the world’s most prestigious recognition campaigns.

The awards have been launched as the top tier of the Green Apple Awards – enabling companies and organisations to win environmental recognition not only for themselves, but also for their countries.

We are delighted that JLL received the silver award for the Carbon Credential’s Collaborative Asset Performance Programme. Through monitoring and adjustment, the centre achieved a 24% reduction in energy consumption in just six months after completion of the programme.

The aim of the Collaborative Asset Performance Programme (CAPP) at 8 – 10 Great George Street was to reduce energy use, costs and carbon emissions and improve conditions for occupiers through better control of plant and via engagement with stakeholders.

Innovate UK research found that ‘average building emissions are 3.8 times higher than design estimate’, a difference known as the Performance Gap. Furthermore, the UK Green Building Council (UKGBC) found that ‘The whole supply chain requires collaborative design and working skills in order to determine the performance targets for the building and to work together to deliver them’.

This site had been in the Hermes Responsible Property Management programme for years, but under-performed against other Hermes assets in Better Building Partnership’s Real Estate Environmental Benchmark.

The Performance Gap was substantial, indicating potential to improve performance significantly.

A site audit identified this could be achieved through analysis of site data, operational efficiency and engagement. To address this Carbon Credentials developed the CAPP, a new approach to optimising performance.

In line with UKGBC’s recommendations, JLL partnered with Carbon Credentials and other suppliers to implement the CAPP, improve management of plant, reduce energy, emissions and ultimately bridge the Performance Gap at George Street.

The improvements at 8-10 George Street were implemented by November 2016. By June 2017, the programme has resulted in 24% verified electricity savings. This reduction in energy spend will pay back the project cost in under 11 months, based on electricity savings alone.

These electricity savings have been verified using ongoing measurement and verification (M&V), in accordance with the IPMVP standard (International Performance Measurement and Verification Protocol). The verified impact is agreed with stakeholders on a quarterly basis.

An ongoing programme is in place to ensure savings are maintained over time, as well as providing monitoring for fault detection and comfort control. Engagement of key stakeholders is central to the CAPP, keeping staff focused on improving energy performance.

In addition to the reduction in energy use, consequent spend and carbon emissions, better control and use of the plant at 8 – 10 George Street has reduced the occurrence of faults and increased the lifetime of equipment. This, in turn, reduces maintenance costs and expenditure replacing broken equipment.

Further successes on other environmental fronts are being recorded as the project continues to grow.


How CAPP Works

Carbon Credentials will work in collaboration with site teams including, operations, facilities management and BMS maintenance providers to ensure that goals are achieved and savings are sustainable.

Programme success depends on both the optimisation of technology and the engagement of people, which is why regular engagement is a core part of the process, as detailed below.
