Energy consumption Part 1

  2. 2. What is Energy? Energy is the power to change things. It is the ability to do work. Energy helps us do things. It gives us light. It warms our bodies and homes. It cooks food and keeps milk cold. It runs our TVs and our cars. It makes us grow and move and think.
  3. 3. Energy Conservation Measures in the Hotel Energy savings means cost savings. Energy is a controllable cost. Hotel energy costs can consume from 10% to 15% of a property's revenue Energy cost has increased considerably. It is necessary to take various energy conservation measures to reduce the energy bill and to have a profitable business.

  6. 6. Building Envelope Keep doors and windows closed when not in use. Open doors and windows allow heated and cooled air to escape and outside air to enter, which requires more energy to keep building at desired temperature. Replace damaged doors and windows with caulk. Damaged weather-stripping allows inside air to leak and outside air to enter, which requires more energy to keep building at desired temperature. Install energy efficient windows. Energy efficient windows used in either new or retrofit situations can cut annual HVAC energy costs by up to 15 % if properly installed. Add window film to windows to reduce energy loss and solar heat emissions through windows. Consider double paned windows. According to Florida Power & Light, energy efficient windows can cut annual energy costs by up to 15 %.
  7. 7. Evaluate insulation in ceilings and add insulation as needed. Insulation can be one of the most important factors in achieving energy efficiency in a building. It works primarily to slow the flow of heat through a building envelope. Consider installing white or reflective roofing. White or reflective roofing helps reflect heat and keep buildings cool.
  8. 8. Lighting Replace standard incandescent bulbs with compact fluorescents or other high energy efficient lighting. Many hotels have realized a significant decrease in energy consumption by making small changes such as replacing standard incandescent bulbs with compact fluorescents. Use the lowest wattage lamp necessary. Using no more light than necessary reduces lighting energy consumption. Use energy-saving fluorescent T5. The energy-saving T5 lamps are considerably thinner than the old-style T12 lamps.
  9. 9. Turn off lights in unoccupied rooms. Create reminder cards for guests and staff to turn off lights when leaving a room. Consider using natural daylight where possible. Using natural light can reduce lighting energy consumption; however, heat loss may occur in winter and heat gain may occur in summer with open draperies and shades. Clean bulbs for maximum efficiency. Bulbs will produce more light after cleaning. Use dimmer controls in meeting rooms. Dimmers control light output so that no more light than necessary is produced thereby reducing lighting energy consumption.
  10. 10. Use occupancy sensors to detect the presence or absence of people and turn lights on and off accordingly. Use an energy-efficient light-emitting diode (LED) night light to eliminate the need to leave bathroom lights on throughout the night. Utilize light colored walls and ceilings
