Land Securities, the largest commercial property company in the UK, now own and manage more than 29 million ft2 of commercial property, from London offices and high street shops to major shopping centres and out-of-town retail parks.
Camfil were asked by Neil Pennell, Engineering Director of Land Securities to evaluate the effect of installing Low Energy Air Filters into the air conditioning system of buildings in the London Portfolio. The project was managed locally by Valentine Alexander, portfolio manager for Land Securities, who identified a suitable site at New Street Square in London.
In July 2009 Camfil engineering staff working together with Inviron FM on site at New Street Square, completed a detailed evaluation of the air filters within one of the air conditioning systems. This evaluation involved collecting performance details on the standard air filters in use at the time, and comparing them to an alternative selection of Camfil Low Energy Air Filters.
This pre-study identified the following savings:
Replacement air filters 15% reduction
Labour to change filters- 64% reduction
Energy to move air through the filters 16% reduction
Tonnes of CO2 16% reduction
These savings were available by fitting Camfil Low Energy Air Filters into the existing filter holding frames as part of the normal maintenance regime. No further investment was required and the new filters were fitted in September 2009.
Prior to this implementation, the air filters were routinely replaced as part of an established Planned Preventative Maintenance (PPM) regime. During this trial project Camfil demonstrated that using Low Energy Air Filters not only reduced the energy consumed, but also doubled the service life of the filters. Consequently the annual air filter cost reduced, together with a reduction in labour and waste cost.
Crucially, because the Low Energy Air Filters are better engineered, the air being supplied into the buildings is now much cleaner (four fold decrease in the amount of particulate in the air). This project has now been rolled out with estimated savings in the London portfolio alone of £250k and 650 tonnes of CO2 in the coming year.
