9. Energy Efficiency Measures Water Heating The advantage of the solar water heater is that water can still be heated using gas while the sun is down. This will allow water heating for members that use the facility in the early morning or evening hours.

![Project Outline ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],The High E Fitness Project aims to decrease energy consumption where possible and make use of energy which goes to waste every day. Fitness centers are often full of electronic equipment and consume lots of energy for water heating and air conditioning. This project will focus on energy efficiency measures that a typical fitness center might benefit from.](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
