Window Films - Energy Conservation | Reduce Your Carbon Footprint
The recent change in building regulations in Approved Document L came in to force on the 1st April 2003, and it addresses the need for more thermally efficient building designs.
The pressure to reduce the energy that we use and Building Managers are focusing on reducing their energy consumption.
Glazing is an increasingly popular structural element with architects, but this has led to greater potential for solar gain which can lead to higher running costs of air-conditioning.
In summer, about 20% of cooling energy load of air conditioning plants in commercial properties is from reducing unwanted solar heat through the fabric of the building. In the winter time glass is a source of heat loss.
- Low-e window film applied to your glass can reduce solar heat gain and dramatically reduce air conditioning-making valuable energy cost savings through the life of the film.
- During the winter months the most significant gap in the building's structure can be the glazing. Winter heat loss can be reduced by up to 30%.
Glass can now be manufactured to incorporate a low emissivity (or low-e) coating that reflects a proportion of the radiated heat generated within a room back into the room, thereby further reducing the heat loss characteristics of traditional glass.
The low-e (low emissivity) window films work in a similar way to this coating but with added benefits:
- Daytime Privacy
- Streamline Cosmetic Look
The payback period of window film installation can be quickly calculated - this is the amount of time taken for the installation to be paid for by energy savings made through the reduction in use of air conditioning units and heating.
EnerLogic is a low-cost, high-return technology that compares favorably to other popular energy-saving measures both in terms of energy efficiency and cost savings. In fact, EnerLogic out-performs most of the alternatives in terms of simple payback. Llumar EnerLogic EU
