A Building Management System (BMS) controls the operation of the largest energy consumers within a building, namely the HVAC plant, which may form up to 60% of the buildings overall consumption.

It is essential that any BMS is configured to ensure optimal performance of the HVAC plant, while maintaining both comfort conditions and a healthy environment, and maintained to a high standard to ensure these conditions are met. Ideally this is carried out in conjunction with an energy metering and monitoring platform to allow performance to be assessed and maintained.

Projects & Installation

E2 provide a turnkey service for BMS installation and upgrade projects, from design through to demonstration.

We specialise in upgrade projects in live occupied buildings ensuring these sites can continue with business as usual, and have delivered projects of this nature across all sectors, including healthcare, tech companies, data centres, pharmaceutical companies, the hospitality industry, central government and major sporting venues.

By ensuring clear communication and working in partnership with our clients we deliver projects on time and on budget with ongoing support and assistance to ensure a smooth transition from our projects team to the buildings FM team.


Optimisation of a BMS is simply the most cost effective way to reduce the energy consumption of a building.

This process involves analysis of the current BMS configuration and identifying improvements to ensure the buildings HVAC plant only operates when necessary, makes optimum use of any free energy sources for heating or cooling and operates to the absolute minimum requirement during times of peak energy costs, where energy is procured via an appropriate contract.

We now offer a funded BMS re-engineering and optimisation facility, Optimisation as a Service (OaaS), over a number of years designed to give immediate energy savings and positive cash flow over an agreed period of time.


In order for a BMS to efficiently control the HVAC plant, it must be maintained to a high standard. A system cannot work efficiently if connected devices are faulty or inaccurate, or if settings have been adjusted without due consideration. A good maintenance regime ensures the BMS continues to operate efficiently and comfort and environmental conditions are maintained.

E2 Services are a leading service and maintenance company with a focus on dedicated and high quality customer service. We provide a comprehensive portfolio of services, from scheduled onsite planned preventative maintenance (PPM) visits to remote support and reactive maintenance.

Our customer focussed approach, excellent reputation and strong relationships give our customers the peace of mind that their BMS is in safe hands.
