Building energy Management Systems (BeMS) are systems which monitor and control building services including heating, ventilation and cooling systems. Through optimisation it is possible to reduce operating costs (energy and maintenance), reduce carbon and improve the comfort of building occupants.
This was a collaborative project between Wates (facility management), Optimised Buildings (Energy and Controls specialists) and the Canadian High Commission (Client). The brief was to upgrade the existing BeMS from the outdated TREND 963 to the latest Trend IQ Vision, along with optimisation of the BeMS incorporating maintenance and monitoring of the heating ventilation and cooling systems. The decision to carry out this work was made to ‘future proof’ the building, preventing existing systems, which are likely to become obsolete in the near future, exposing the Canadian High Commission to a risk of systems becoming inoperable or inefficient.
As the Canadian High Commission is based in two separate buildings, over 200 feet apart, it was important to be able to link the BMS systems in the two buildings in terms of monitoring and saving energy. With the two systems linked the monitoring is simplified and much more manageable to the onsite maintenance. Through the IQ Vision platform the Wates facilities team will be able to manage critical alarms quickly, make adjustments to the system more easily while minimising the energy consumption.
Optimised Buildings took an innovative approach to the project combining the optimisation of the BeMS, an on-going BeMS maintenance/optimisation service and the use of analytics to ensure optimum performance 24/7. Inefficiencies and anomalies are identified and rectified quickly using the team of analysts working at the Optimised Bureau in the Midlands to analyse data, reporting back with recommendation and energy conservation measures. This leads to big savings in operating costs and energy consumption, alongside improved comfort levels for occupants. In fact, it is possible to save around 10% of a commercial building’s energy spend using these measures.
To minimise any site disruption during the upgrade the two systems will be run parallel for a period of time. By the time the existing Trend 963 is removed the building should be running smoothly, comfortably and cost effectively. A comprehensive timetable of works has been drawn up to ensure as little disruption as possible to the occupants. This involves collaboration of all parties involved in the project to fit in with effective ongoing operation of the building and allow crossover and checks to be completed to maintain comfort levels and allow for security constraints, due to the sensitivity of the site.
