Essay about Technological Product Innovation for Sustainable Energy

959 Words 4 Pages
Technological product innovation for sustainable energy in buildings generally comprises two categories of technical solutions: energy-efficient technologies, and renewable energy technologies (Brindle et al., 2007).

Energy efficiency is the use of less energy than the industry standard for ventilation, heating, cooling, an artificial lighting to fulfil desired thermal comfort and task requirement of building occupants (Intrachooto, 2002). Energy efficiency often take two forms: reducing the demand for energy, and using fossil energy as efficiently as possible. Reducing energy demand can be achieved by avoiding energy waste and implementing energy-saving measures (Action Energy, 2002). This should be accomplished while maintaining

Renewable energy technologies, on the other hand, require additional machinery and equipment to generate electricity and produce heat (Intrachooto, 2002). It comes from sources that are essentially inexhaustible such as the sun, the wind, flowing water and the heat of the Earth, or replaceable fuels such as plants. Ideally, as Dincer and Rosen (1999) advocate, only energy resources which have no environmental impact should be utilised in a society pursing sustainable development (Dincer and Rosen, 1999). As well reducing stratospheric ozone depletion, acid precipitation, and the greenhouse effect, renewable energy resources are considered one of the most efficient and effective solutions (Dincer, 2000). Appendix A reviews some of the most common renewable energy technologies used in school buildings. The technologies range from those capable of producing electricity such as wind turbines and photovoltaic panels to those producing heat such as biomass boilers, solar panels and ground source heat pumps. Some technologies are simultaneously producing both electricity and heat such as Combined Heat and Power (CHP) technologies. The review provides a description of the technology, the type of energy it generates, where it can be used, and key requirements/constraints to be considered. The DCSF (2007b) guidance advises that for
