There are many issues that are generally covered under 'energy efficiency'. These include:
- Utility Cost Reduction
Companies aim to reduce energy usage and therefore utility costs to the greatest extent possible. Such aims cover, for example, heating, cooling and ventilation, lighting levels and water conservation.
- Energy Conservation
Companies first perform an energy audit, covering loads, devices etc. Enabling future improvements, such audits focus on time-of-use, conservation measures possible etc. and propose measures that are both operational and technological in nature. Measures include cost, ease of implementation, energy saved, as well as cost reduction in general.
- Water Conservation
Water conservation efforts included the conversion of water cooling systems to closed-loop systems, recirculating the water instead of piping in public-supply water, and the elimination of nonessential processes and modification of piping and timer systems.
Employee awareness and participation are an important contribution to efforts in achieving energy efficiency.
