The Biggest Energy Loser Challenge, created through a partnership among the Department of Energy, Oak Ridge National Laboratory and Southern University, focuses on energy forms, usage and consumption. Student tasks include conducting a home energy audit in which they calculated the amount of electricity consumed by everything from clothes washers and dryers to personal computers, light bulbs and televisions.

Students began by learning about renewable (solar, wind, biomass, hydroelectric and geothermal), non-renewable (oil, natural gas and coal) and nuclear energy as well as the types of energy used in buildings. They also learned that buildings account for 49 percent of the energy consumed in the U.S. followed by transportation at 28 percent and industry at 23 percent.

Optimise the design with focus on energy efficiency Utilise natural design solutions for heating and cooling Use renewable energies either integrated into the building or taken from the nearby collective energy system and electricity grid Include material energy and the CO2 footprint in the overall energy calculation Evaluate per m2 and per occupant

“Currently, energy costs account for approximately 10 to 15 percent of all hotel expenses,”

By implementing solar cogeneration, we will be able to reduce our energy expenses and help the environment by reducing our consumption of traditional energy sources and our greenhouse gas emissions.”
