Case Study - Corporate Land Securities, the UK’s largest property management company, saves £250k and 650 tonnes of CO2 by installing Low Energy Air Filters Client: Building: Environment:

Land Securities New Street Square Development City Centre location

Land Securities, the largest commercial property company in the UK, owns 2 and manages more than 29 million ft of commercial property, from London offices and high street shops to major shopping centres and out-of-town retail parks. Land Securities’ Engineering Director Neil Pennell asked Camfil to evaluate the effect of installing Low Energy Air Filters into the airconditioning system of buildings in their central London Portfolio. Valentine Alexander, Land Securities’ portfolio manager, who identified a suitable site at New Street Square in London, managed the project locally. In July 2009 Camfil engineering staff, working with Inviron FM on site at New Street Square, completed a detailed evaluation of the air filters within one of the air-conditioning systems. As part of this evaluation, we collected a wide range of performance measurements on the standard air filters in use, analysed the findings and compared performance against an alternative selection of Camfil Low Energy Air Filters. From this exercise, we identified the following savings opportunities:    

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 achieved by fitting Camfil Low Energy Air Filters into the existing filter holding frames as part of the normal maintenance regime. No special 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 costs.

Our specialist work for this client....    

Expert evaluation of existing air filter performance Benchmarking against alternatives Identifying savings opportunities for all systems in New Street Square Installing replacements to optimise performance, energy and costs savings

Delivering benefits including.... 

 

Cleaner air! Achieving a four-fold reduction in the amount of particulate in the air Using Low Energy Air Filters not only reduced energy consumption but also doubled the filters’ service life Reducing annual air filter cost Reduced labour and waste costs

The client view

Crucially, because the Low Energy Air Filters are better engineered, the air 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.
