Project OutlineThe High E Fitness Center Project• General Data and Background • Energy Efficiency Measures• Funding• Implementation• Appropriate Measurements
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.
Health Club Industry Data
As of January 2010, The International Health, Racquet & Sportsclub Association (IHRSA) Research Department determined that there are:
• 30,022 health clubs in the US• 45.5 million health club
members • Total U.S. Industry Revenues
for 2008: $19.1 billion

Energy Efficiency Measures• Given that this particular
YMCA has already taken measures to increase Energy Efficiency, the following areas were considered for improvement:
• Water Heating • Windows and Doors• Air Conditioning• Generating Power from
Exercise Equipment
Magdalena Ecke YMCA
• Founded in 1965• This particular YMCA is rated one
of the most active and progressive centers in the country.
• 20,315 members• This project will focus on the
facility that includes several dance studios, weight lifting room, cardio-exercise room, spin room, gymnasium, locker rooms and the preschool.

Energy Efficiency MeasuresWater Heating
Water Heating• Water heating makes up 75% of the total gas
consumption at the YMCA. (excluding pool heating)
• Currently there are two 100 gallon gas water heaters.
• Low flow shower heads and faucets have already been installed prior to this evaluation. Therefore, an active solar water heater could be the most effective way to increase energy efficiency.
• A solar heater can offset the equivalent of 40% to 100% of the carbon dioxide emissions of a modern passenger car.
• Annual utility costs for solar water heaters have been 50% to 85% lower than those for conventional water heaters.
• Routine maintenance includes an anti-freeze check every two years. The glycol is usually food-grade propylene glycol because it is non-toxic.

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.
Energy Efficiency MeasuresWindows and Doors
• Double glazed windows can save up to 32% of annual heating and 16% on cooling energy cost.
• Other benefits include noise reduction, low maintenance, and humidity control.

While windows and doors have a significant up front cost, their ability to increase energy efficiency and reduce noise makes them a valid investment.
Energy Efficiency MeasuresHeating and Air Conditioning
Energy Efficiency MeasuresHeating and Air Conditioning
According to the D.O.E…• a heat pump can trim the
amount of electricity you use for heating by as much as 30%–40%
• High-efficiency heat pumps also dehumidify better than standard central air conditioners, resulting in less energy usage and more cooling comfort in summer months.

Because of its location near the ocean this particular facility does not experience a extreme temperatures like other areas in San Diego County. Which makes the heat pump a perfect match.

Energy Efficiency MeasuresExercise Equipment
• People will always exercise to maintain good health and physical strength.
• Why not harness the energy from all the equipment they use?
• The possibilities are endless…
Energy Efficiency MeasuresBike Power Generator
The Green Revolution does just that.
A small generator is connected to the front wheel of a stationary bike.
That generator send that energy through a cord to an inverter that can connect up to 40 bikes.
The inverter changes DC to AC and supplies energy to the load of the building or sends it back to the utility grid.

Although the energy production is relativelysmall, this technology could be more valuable as an educational tool for the community.
Energy Efficiency MeasuresBike Power Generator
• The bike power generator could be used in The Power Hour Project, an outreach program in cooperation with the YMCA and SDG&E, in which high school science classes could learn about the basics of energy generation and energy efficiency.
• The bikes could also be used for fundraising. A Spin-a-thon could allow participants to generate money based on the energy production of the spin class.
ImplementationThe Roof Raisers
• The Roof Raisers was founded in 1971 and was made up of local leaders of the Encinitas business community.
• Their original goal was to generate additional funding to complete the then-new YMCA.
• Since then, the organization has generated over $3,600,000 to fund improvements for the center.
• 100% of funding for the energy efficiency measures will be sought out by the Roof Raisers.

Implementation
Hold a fundraiser event at the YMCA gymnasium with the Roof Raisers and SDG&E.
First, replace windows and doors, heat pump and solar wand.
Second, unveil energy generating spin class and The Power Hour Project .
