Building Management System services

A properly functioning Building Management System (BMS) is crucial to minimising energy consumption – yet most are wasting vast amounts of energy.

The Green Consultancy offers a comprehensive range of services to ensure that old or new BMS are working at peak efficiency.

How your BMS may be wasting energy

A 3450_bms4 - - beckyBuilding Management System or BMS (otherwise known as a Building Energy Management System - BEMS) controls and monitors a building’s mechanical and electrical equipment such as air handling, heating and cooling, lighting, power and security systems - and is an essential tool in making sure that plant operates efficiently

However the majority of BMS significantly under-perform. Even organisations that employ full time BMS engineers, or have BMS maintenance contracts, frequently have seriously dysfunctional systems. This results in the massive wastage of energy, increased costs and uncomfortable environments for building users. For example, a recent TGC audit identified that poor BMS control of a single air handling unit was wasting £30,000 per year.

An underperforming BMS can be due to:

  • inappropriate specification or control strategy
  • incorrect installation or commissioning
  • sensors faulty, poorly installed or positioned
  • settings not updated to suit changing patterns of building use etc
  • inadequate training
  • inadequate maintenance

A properly functioning BMS should deliver energy efficiency savings in the order of 15-20% yet our extensive experience demonstrates that most are wasting 15-50%. Improving the operation of your BMS is probably the single most cost effective energy efficiency measure you can take.

The Green Consultancy (TGC) offers a comprehensive range of BMS services tailored to suit your circumstances and budget. These fall into the following three categories.

  • Savings identification
  • Opportunity implementation
  • Upgrades and new BMS

Where they go beyond consultancy into “hands on” software and hardware engineering we work with trusted independent BMS specialists expert in all manufacturers’ equipment. Alternatively, clients use their existing contractors to implement our recommendations and, in some cases, we are asked to work with them.

Savings identification

We offer two levels of forensic investigation as follows. Crucially, both are informed by our unique, rigorous and scientific Energy Efficiency Methodology.

BMS health check

A Green Consultancy BMS health check is an investigation of the BMS “head end” to identify the scope for energy savings opportunities for a fixed fee of only £1950 +VAT. Read more...


BMS audit

A Green Consultancy BMS audit is a full investment grade investigation of the BMS and plant controlled to identify opportunities for improvement, costs and return on investment with guaranteed savings. Read more...

BMS and eSight M&T System Optimisation for University of Leeds

“The Green Consultancy’s BMS and eSight M&T System Optimisation work has enabled my team to make substantial energy savings and to manage energy more effectively to drive down future costs and carbon emissions. In addition, we have been able to apply the learnings to extend the optimisation work to the remainder of our estate. In my opinion, the value of TGC’s contribution significantly outweighs their fees.”

Luke Gallagher, Energy Manager

BMS Services for University of Worcester

Following a BMS Health Check we provided a new strategy and full tendering support for a replacement BMS.  These were some of the services delivered within a three year contract for energy management involving a consultant being on site for up to three days per week.

"The Green Consultancy have proved to be adept at understanding the requirements of a complex organisation across an extensive estate and have worked with colleagues in the University of Worcester to help us better understand our priorities in relation to carbon reduction.  Their support for the estates team is working extremely well and in addition to resolving issues and making efficiency gains, members of the in house team are also increasing their knowledge base. I would not hesitate to recommend them to others."

Mark Hughes, Director of Estates & Facilities
