About BEMS

Our purpose is to provide a comfortable environment for occupants, efficient operation of mechanical and services and to offer a level of service good enough for you to recommend us to others.

We are an independent company specialising with Building Energy Management and Automatic Control Systems. We use a range of manufacturers products to provide modern, efficient and user-friendly building energy management systems, our level of service is personal and and we have the capacity and incumbent capability to deliver large and small projects, maintenance, energy and integration.
Using our knowledge of manufacturers products and controls systems coupled with a forward thinking approach to service provision we deliver a high quality level of service incorporating our main activities: PROJECTS / MAINTAIN / ENERGY / INTEGRATE. Please contact us for more detail regarding BEMS and our services, we offer an open invitation for you to come and see us within our London offices.


A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering.

Fast Track projects are a way of life for bems, we understand the world of contracting and the integral part the building energy management system plays within the larger scope of a construction project. Our quality assurance systems ensure that projects are delivered to the highest standards whilst working safely, diligently and with attention to detail.
We select the correct products and have incumbent capability to design, install, integrate, commission and support modern, open, building energy management systems. Our focus and drive is to provide industry leading services for building energy management and control systems design, installation and commission.

If you don't understand how to run an efficient operation, new machinery will just give you new problems of operation and maintenance. The sure way to increase productivity is to better administrate man and machine.

W. Edwards Deming
Service, support and maintenance of any building energy management system is fundamental for its operation, performance and ultimately the consumption of the mechanical and electrical services it controls. We have a team of dedicated engineers providing reactive, preventative and energy based activities and we follow up our attendance with robust reporting, administration and subsequent remedial proposals. We understand that clear and concise reporting is as important as the engineering activities undertaken to the building energy management system.
Our options for maintenance of building control systems are provided as basic, intermediate and advanced options, we tailor these options to suit the building, its occupants and the sector that the client operates within. Our basic service option is inclusive of system back-ups and operational checks with intermediate and advanced options giving higher frequency of visits and includes spares and consumables for the systems should this be a requirement. Our energy based maintenance activities are driven by the consumption of main plant and seasonal trends for hours run operation we ensure that the BEMS system is functional as well as looking at the efficiency of the M&E services.

If you cannot measure it, you cannot manage it

David Petraeus
HVAC services typically account for up to 40% of a buildings energy consumption and is usually the 3rd highest outgoing overhead for a company. We offer an organic approach to energy related services consisting of auditing, AM&T, metering, dashboards and visual displays for energy consumption usage.
We use CIBSE TM22 to undertake building energy surveys, we audit the BEMS specifically for energy based software routines inclusive of compensation, night set-back, free-cooling and optimisation. We recommend and implement software and hardware changes to provide efficient mechanical and electrical services, We also undertake metering, sub-metering and consumption based services to ensure that systems are benchmarked and energy profiles are within agreed parameters.

Customers require the effective integration of technologies to simplify their workflow and boost efficiency.

Anne M. Mulcahy
Integration is now a major part of any building energy management system, we are working with the modern building protocols and data exchange of information using Bacnet IP and MSTP, Modbus, M-Bus, LON, Niagara, En-Ocean, KNX & Sedona, in most instances we can provide an interface to third party equipment using the BEMS hardware and software we specialise with.
Typically we are using integration to the BEMS for metering of electric, gas & water, AC Equipment (Daikin, Mitsubishi, Sanyo, Toshiba), Downflow / CRAC Units (Denco, Stultz, Airedale etc), Terminal and Unitary controllers, Heat Pumps, Ground and Air Source Heat Pumps, Chillers, Pumps, Boilers. Our integration methods are robust and provided with communications alarming and reporting to ensure that should either system not be receiving information alarms are generated and transmitted.

Here are some examples of the works we have undertaken or are currently in the process of completing, if you would like more information related to any of these then give us a shout, we are keen to give details of what we are capable of and how we go about providing the level of service our customers have come to expect from BEMS.
