  • 1. High Efficiency Fitness Center By Jesse Rogers SDSU, Green Energy Management Energy Efficiency, Evaluation and Design
  • 2. Project Outline
    • The 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.
  • 3. 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

  • 4. Health Clubs Consume Energy for… Treadmills Air conditioning Showers Lighting Stationary Bikes Weight Lifting Equipment Televisions Administrative Activities Heating and cleaning pools
  • 5. 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
  • 6. 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.

  • 7. Energy Efficiency Measures Water 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.

  • 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.   ( 2) Butler Wands for 100 Gallon Water Heaters Cost per Therm $0.80 Annual Consumption of Gas in Therms 21,789 Annual Cost of Gas in Dollars $17,431.20 Initial Cost Installed for Two Butler Wands $15,000.00 Estimated Increase in Energy Efficiency According to Manufacture 60% Estimated Percentage of Consumption in Relation to Other Gas Consuming Equipment 75% Estimated Increase in Energy Efficiency for Total Gas Consumption 45% Energy Savings in Therms 9805.05 Annual Savings in Dollars $7,844.04 Simple Payback 1.912279897
  • 10. Energy Efficiency Measures Windows 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.

  • 13. Energy Efficiency Measures Heating 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.

  • 14. Energy Efficiency Measures Heating and Air Conditioning 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.   Commercial Heat Pump Cost per kWh 0.16 Cost per Therm 0.8 Annual Consumption of Electricity in kWh 423,600 Annual Consumption of Gas in Therms 21,789 Annual Energy Cost in Dollars 84,711.47 Initial Cost Installed $16,000.00 Estimated Increase in Energy Efficiency According to Manufacture 40% Estimated Percentage of Consumption in Relation to Other Gas and Electric Consuming Equipment 50% Estimated Increase in Energy Efficiency for Total Electric and Gas Consumption 20% Energy Savings in kWh 84720 Energy Savings in Therms 4357.8 Savings in Dollars $16,942.29 Simple Payback 0.944382148
  • 15. Energy Efficiency Measures Exercise 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…
  • 16. Energy Efficiency Measures Bike 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.

  • 18. Energy Efficiency Measures Bike 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.
  • 19. Implementation The 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.
