Energy efficiency in buildings Today’s increased use of glass in architecture and the ever growing focus on energy efficiency are driving developers, owners and occupants to demand higher performing products than ever before. Buildings are increasingly becoming the focus of energy-saving initiatives because, not only are they a significant energy consuming sector, but the technologies and products to make buildings substantially more energy-efficient have already been developed. Developments in glass technology, such as low-emissivity (low-e) and solar control, have revolutionised the potential of glazing applications. We are continually developing products to help specifiers achieve reduced carbon emissions. In buildings that would traditionally be air conditioned or use high levels of artificial lighting, installing solar control glass rejects unwanted solar radiation but allows valuable daylight to enter the building. Conversely, our energy saving low-e glass reduces heat loss from buildings and, in some cases, our products combine both low emissivity and solar control performance. Advanced products from the Pilkington range enable buildings to be both energy-efficient and yet be aesthetically attractive. Glass can be used as a positive contributor to low-energy performance, whilst creating interiors that are comfortable and façades which connect the occupant with the outside world. A good choice of glass helps to manage internal comfort by controlling direct radiation, glare, internal temperature and light levels as well as helping to reduce running costs.
