Rex House Smart Building Insight Programme

Delivering improvements in energy performance, maintenance and comfort levels

What are the 4 key objectives for the programme?

2. Increase tenant comfort and reduce complaints

1. Significant electricity and gas savings

3. Best-practice collaboration between site teams, the landlord, tenants and contractors.

4. Increased efficiency of equipment leading to longer life of key plant

The Programme

Rex House was identified by BNP Paribas Real Estate, The Crown Estate and Carbon Credentials as a site with significant potential to improve its energy and carbon performance.  A strategy was implemented to tune the energy performance of the building without reducing the quality of tenant experience, increasing its value within the St James portfolio as a result.

The Smart Building Insight Programme uses innovative smart building technology to drive energy savings through site optimisation. A core goal of the project is improved wellbeing across the site, and there has already been a reduction in complaints and site call outs.

“The level of insight provided by the programme at Rex House allowed us to quickly achieve significant energy savings and has driven proactive maintenance to rectify site issues.”

– Edward Dowden, Technical Services Manager

The Process

Stage 1:

We installed a Smart Building Gateway which fed back the Building Management System (BMS) data to Carbon Credentials’ online analytics platform, ADAPt. We were able to identify and implement a number of optimisation opportunities using a combination of machine learning and expert engineering analysis of all the site data. We were even able to implement some opportunities on day one of the programme.

Stage 2:

Across Rex House’s seven floors it had been noted that conditions varied quite significantly, causing wellbeing and comfort issues in certain areas of the building. We installed 12 IoT sensors to monitor factors including CO2, temperature, humidity, light and motion.  These sensors highlighted variations including temperature spikes outside of the optimal comfort zone, CO2 reaching levels that could impact productivity and humidity levels that threaten wellbeing.

Outcome

10%

reduction in electricity consumption

£22,000

annualised savings

40%

reduction in gas consumption

Collaboration was key in driving the success of the programme and was ensured by parties from BNP Paribas Real Estate, NG Bailey and Carbon Credentials all working together and being aligned in their desired outcome of the programme. Through the data that was visualised on the ADAPt portal a number of energy savings were implemented across the site as well as driving investigations into site conditions.
