Efficient Air launches HVAC System Optimiser significant savings by better control of HVAC components

A new service to be launched at Nemex 2007 by leading HVAC energy saving specialist Efficient Air is already yielding significant benefits for a fast growing University, and attracting considerable interest from large energy users throughout the UK.
The HVAC System Optimiser has been developed following a detailed study by Efficient Air engineers on installations throughout the UK, which showed that BMS controlled systems were not detecting inefficiencies in the HVAC process that result in higher energy usage and increased costs.
“Our investigations were showing that dramatic energy rises were occurring as a result of conflicting control strategies, sensor drift and manual overrides, and they were not being detected,” explains Efficient Air’s Technical Director, Steve Biggs.
Efficient Air’s solution was to devise a HVAC Systems Optimiser that uses the company’s unique knowledge on how to fine tune the performance of HVAC components operating within an air handling system. The aim is to optimise the energy consumed whilst maintaining the desired environmental conditions.
Once the system is optimised, a WEB based viewing system will enable the energy manager to check whether the HVAC systems are operating within the set parameters. If not, an alarm will be activated to instruct either in-house or Efficient Air engineers to carry out rectification work.
Brighton University, who invested £1800 with Efficient Air on a 12 month Optimisation Support contract for the main air handling unit at its Watts Building, has reduced its energy bill by £5,500, equal to 7,360 kW/hrs for electricity and 208,891 kW/hrs for gas, improving its HVAC systems energy performance by an additional 20 per cent per year. The savings were achieved by accurately logging airflow rates, temperatures and air quality over a 3-month period and implementing a quick win and capital investment programme to guarantee maximum payback.
David Anderson, Energy Manager at the University was clearly pleased, and said: “We were delighted when Efficient Air delivered a 40 per cent reduction in fan motor power as a result of the initial project. What is doubly pleasing is by following this up with the new optimisation support service, we have gained further savings to the overall e
