WEMS Wireless I/O & BEMS System

BACnet compatible wireless I/O and BEMS

Ideal for creating distributed controls in a large building, or deploying as a complete BEMS system at multiple locations.

WEMS flexible I/O system can be used as either a fully-fledged BEMS system, or as stand-alone wireless I/O that can be integrated into another BMS system via the ubiquitous BACnet IP protocol. Furthermore, WEMS can be used to create wireless, wired and hybrid communications networks.

What our customers think...

TransPennine Express logo

Environment & Emergency Planning Manager

“...there is a distinct downward trend in energy usage across all sites. Indeed, the figures show the lowest energy consumption for five years over comparable periods for those stations that haven’t had major infrastructure upgrades...”


BAE Systems logo

Energy Management Lead

“I’ve been really impressed by Aimteq’s project management and communication throughout. They have bent over backwards to ensure smooth project delivery. Furthermore, they are very dedicated and have come back to the site to resolve a few very minor snags.”


KBR logo

Real Estate Services

"We are very happy with the project, not just because we are achieving our desired outcomes, but with the service provided by Aimteq."


A&B Engineering logo


“We selected Aimteq for a number of reasons, not least their tender performance, keenness to do the project and the opportunity for both businesses to develop a working relationship. The desired outcomes have absolutely been achieved. Aimteq have now demonstrated they are a perfect partner for A&B Engineering going forward.”


BT Logo

Director of energy & carbon

“The WEMS technology installed by Aimteq has underpinned the success of our smart energy programme at BT. It gives us remote control over the air handling systems and enables us to optimise energy usage. As a result of the proven success, we have now agreed a contract to expand the programme further.”


Go-Ahead group logo

Energy & Environment Manager

"Aimteq installed the WEMS system and I have seen my energy consumption drop by over 40%. If the system gets overridden, Aimteq work with our sites to resolve the problem and turn the system back to auto control. This maintains our environmental conditions and enhances our savings."


DW Sports Fitness Logo

Utilities & Property Systems Manager

"For us, technology must be a safe investment, must not affect the customer experience in our fitness centres, and must go on in the background so as not to cause distraction or disruption. For these reasons, Aimteq’s installation of a wireless solution such as the WEMS one made perfect sense."


Stagecoach UK Bus Logo

Director of Safety, Health & Environment

“Another reason we opted for the Aimteq solution was the bureau service, which meant we could delegate the controls to an expert, who could remotely optimise energy consumption across all sites on an ongoing basis.”


G4S logo

Operations Director, Carbon & Energy Solutions

"We have used Aimteq on many sensitive government buildings and projects. At these locations, discretion, along with sensitivity towards the environment and the building occupants is paramount. As such, disruption in these areas must be kept to a minimum. We have found Aimteq to be a progressive company in their approach to not only building controls, but in the suggestion and implementation of energy improvements to building controls."


Colt logo

DCS Incident Manager

"When Colt started to expand beyond London in the late 1990s we needed some form of building management technology to support our remote sites and deliver alarms to a central server. Today we have scores of sites and Aimteq has been an excellent support partner throughout our evolution. We have almost day-to-day interaction with Aimteq and regular reviews with their team."


Matalan Logo

Environmental Manager

"Matalan has made the commitment to have the WEMS system installed by Aimteq in all our retail outlets. The installed stores have shown a considerable reduction in energy consumption of circa 18% and this is reflected in our energy bill which has decreased dramatically since implementation."


Boots logo

Head of Engineering

“Aimteq take responsibility to not only lower the costs of running a retail estate – but they bring a ‘can do’ attitude that is refreshing in the market place. By constantly investing in the R&D of their product suite, they bring innovation and creativity into our estate.”


Tui logo

Facilities, Contracts & Energy Manager

"Over the 61 sites we’ve seen a 32.92% drop in our consumption, which translates to a considerable saving on our energy spend and correlates well with our sustainability policy. Further to that, the experience dealing with Aimteq was seamless from start to finish."


Pizza Hut logo

Energy Manager

"The bureau offers fantastic customer service, and importantly, is operates 24/7; longer than any of the bureau services we researched. We get through to a real person straight away and changes are made quickly."


Debut logo

Project Manager

“…please pass on my thanks to your engineer for the call out. He was persistent and got a resolution and was happy to explain the problem as he went along. Excellent service.”
