Identify and implement all available energy conservation strategies. Conservation is less expensive than any energy retrofits. Reduce energy usage by targeting the largest component of energy use first. Space conditioning (heating or cooling) is often the largest component of energy usage in a hotel and should be addressed by preventing heat transfer within the building. Improving windows, decreasing infiltration, insulating exterior partitions and ductwork, and retrofitting lighting fixtures are effective strategies. This can be identified at the design stage or during operation with the aid of electricity meters. Shifting electricity usage to off peak times may also reduce costs.
Make it a priority to save energy wherever possible. Conservation measures involve little investment and are the most cost-effective means of reducing operating costs.
