Demand for air travel is at an all-time high and growing at an unprecedented rate. An industry forecast¹ indicates that if unconstrained, demand would grow approximately4% per annum. This rate would nearly double passenger numbers at airports by 2020 (4.2 to 7. 4 billion). In reality, growth will be constrained by capacity-issues in air space and at airports.
Two consequences of capacity restrictions will be more delayed flights and passengers having to spend more time at airports. Airport buildings are ventilated to provide breathing air for human comfort and health.
Large amounts of external air are drawn into airport buildings and this air will be heavily polluted. Airplanes are not the only source of pollution at airports. The ground traffic needed to support air operations cannot be ignored. Air quality is degraded by the operation of; push-back trucks, passenger buses, staff buses, baggage wagons, cleaning team vehicles, catering vehicles etc.
In fact, because most of these vehicles are powered by diesel engines and they operate in very close proximity to the gates, they are probably responsible for the greater proportion of pollution inside the terminals and other airport buildings. Continue reading
Pollen, most commonly associated with Hay Fever sufferers, can cause significant problems for Building Managers too and not necessarily in the way you might think.
With greater air conditioning requirements and cooling loads during times of increased ambient temperature, HVAC equipment works at a higher capacity to draw in the high volume of air require. As a consequence, pollen, along with insects and other airborne particulates, gets drawn onto condenser and evaporator coils, creating a blanket-like layer across the surface of the coil fins.
Any clogging caused by airborne debris significantly reduces the air passing through the unit, meaning that fan motors and compressors are required to work harder in order to operate correctly. This significantly increases energy consumption, along with the risk of plant breakdown, which could be extremely costly to facilities managers and employees alike. Continue reading
Reducing the power consumption of HVAC systems with energy efficient filters like Camfil’s that also improve IAQ – is a practical way to mitigate climate change and combat the health threats of indoor air pollution.
The savings are true and tangible if customers make the right decisions and are willing to pay for the best available air cleaning solutions.
The threshold may be slightly higher in terms of filter prices, but the benefits are far greater because quality filters last longer, clean better, save more energy and do not have to be changed as often.
This adds up to a lower total cost of ownership (TCO). The economic benefits, measured in terms of energy savings and cost reductions, surpass the initial purchasing cost for higher quality products.
We have our own unique R&D resources, such as our state-of-the-art Technology Centre in Sweden, plus tech centres in other world regions. One primary focus of our research is the overall life cycle performance of our products: how we deliver air quality of maximum benefit while minimizing our environmental impact. Continue reading
