QUICK WINS FOR ENERGY SAVINGS IN BUILDINGS Choosing low energy air filters for both optimised energy performance and indoor air quality February 2014

Quick wins for energy savings in buildings Choosing low energy air filters for both optimised energy performance and indoor air quality _________________________________________________________________________________ Executive Summary HVAC systems heat cool and clean the air distribution within some 200,000 buildings in the UK. That’s approximately 7,300 organisations consuming 35% of the UK’s energy consumption. The Federation of European Heating, Ventilating and Air-Conditioning Associations have estimated that within the EU there is a potential annual saving of 5TWh available by switching...

Camfil know that saving energy is one of the most challenging tasks facing the built environment today. Our low energy air filter products provide the highest indoor air quality, with the lowest pressure drop, which deliver the biggest energy savings to customers, without compromising air quality. Property, Estates, FMs, Building and Energy Managers are realising the substantial financial and energy saving opportunities that exist by replacing existing air filters with our award winning filters. In 2013 we delivered ‘identified energy savings’ of over £1 million to UK sites by installing low...

The Solution Air filters are hidden in various plant rooms within the air handling unit, they significantly contribute to the resistance of the fan motor. Air filters are designed to be changed unlike other components within the ventilation system, and consequently do not put any pressure on capital budgets when upgrading to a low energy filter. Would you spend a pound to save £5 or £10? Camfil can demonstrate how better air filters will lower Total Cost of Ownership (TCO). Low cost filters clog quickly, causing a higher resistance to the airflow which results in an energy cost penalty. Camfil...

terms of installation, these low energy air filters in 90% of cases can be retro fitted in the existing framework which means that payback is usually 1-3 months. In other cases, new framework may need to be installed with the low energy air filters and the payback is extended but always within a 12 month revenue period. In our experience, these upgrades are resourced within the revenue budget with no need for capital expenditure. Placement of low energy air filters in air conditioning systems enhance the system efficiency by maintaining the heat transfer efficiency of the heating and cooling...

The Life Cycle Cost for a filter is the cost of the: Labour (installing and replacing) Energy consumption Cleaning of ventilation system Disposal of used filters_ The cost saving example In a typical building, for example a hotel, containing 20 air handling units (AHU's) installed with 10 filters in each (200 pre and secondary air filters) energy savings can typically amount to £14,000 per year, every year, simply by upgrading to low energy air filters. Other savings include • 50% labour time (you only change half as many filters) • 50% waste costs (you only dispose of half as many filters) •...

No compromising on air quality The function of an air filter in air conditioning applications is to clean the air that we breathe to a prescribed level. (F7: minimum class filters to EN779:2012) In order to achieve this, the air filter must perform at this level throughout its installed lifetime. Only filters that are manufactured using fine fibres can reliably perform at this level as the interstitial holes between the fibres are smaller and will trap smaller particles. It is this balance of fine fibres and engineered construction that allows a low energy air filter to deliver optimised energy...

consumption and environmental impact for sustainability reasons, building owners also need to cut operating costs as power prices increase. Selecting the right quality air filters with the lowest energy consumption can boost their energy efficiency and also increase lAQfor a better and healthier work environment. European buyers of filters should check that their supplier is Eurovent-certified. There should be Eurovent labels on all filter boxes and filters should have test protocols based on £fHO£NO CLASS Nominal airflow Annual Energy Consumption: * Eurovent Certification Company is the representative...

Summary With 50 years of experience in air filtration products and solutions, Camfil delivers value to customers all over the world while contributing to something essential to everyone – clean air for health, well-being and performance. Our products address the energy considerations that all organisations face. In 2013 we supported site and energy teams, in estates across the UK, presenting opportunities for Engineers to deliver identified energy savings (Over £1million) for clients and stakeholders. This is supported by high profile case studies. Our filters deliver the required air quality,...
