We helped the financial services giant develop smart buildings to save energy and drive proactive maintenance.

annualised savings
reduction in gas consumption

Smart buildings for sustainability

BNP Paribas’ property business, BNP Paribas Real Estate, chose Carbon Intelligence to help implement a smart buildings programme – delivering improvements in energy performance, maintenance and comfort levels.

The key objectives were:

  • Significant electricity and gas savings
  • Increase tenant comfort and reduce complaints
  • Best-practice collaboration between site teams, the landlord, tenants, and contractors.
  • Increased efficiency of equipment leading to longer life of the key plant

Smart Building Insight Programme

Rex House was identified by BNP Paribas Real Estate, The Crown Estate and Carbon Intelligence 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.

Benefits beyond sustainability and savings



Positive interactions with staff and tenants, increasing engagement and wellbeing.


Evidence of operational opportunities and clear business cases for capital investment.


Creation of best in class case study to support marketing and boost company image.

The Smart Building Insight Programme had a positive impact on three core aspects of BNP Paribas Real Estates’ business: the brand, the people and the facilities.

Stages of the programme


Stage 1: We installed a Smart Building Gateway which fed back the Building Management System (BMS) data to Carbon Intelligence’s 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.

Collaborative advantages

The collaboration was key in driving the success of the programme and was ensured by parties from BNP Paribas Real Estate, NG Bailey and Carbon Intelligence 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.
