When we work with new clients, we recognise the need to demonstrate our capabilities and not rely solely on our reputation. Where appropriate, we will carry out a preliminary survey to provide an expert, independent view on the opportunities for energy reduction.
- Full review of BMS function – to ensure that plant (which was mostly modern and in good condition) was operating as per design
- Inverter control – some of the benefits of a modern sophisticated BMS control strategy were lost when pumps and motors could not run at variable speed, as conditions dictate. Installing inverters has overcome this.
- De-centralised hot water services – in a large building such as this, point of use water heaters bring significant benefit over running the central boilers for extended periods to serve all areas
- Lighting upgrade – the building contained a number of older lamp types which could be upgraded as a project with a good payback on investment
Benefits: Collectively, the initiatives identified and agreed as feasible represented a 28% reduction in annual electricity consumption and a 21% reduction in gas consumption. All of these measures had a reasonable payback, and we were instructed to project manage the implementation works, which were successfully completed on time and within budget.
