  1. Clyde Lobby Windows Heat Loss Winter 2008 Boyd Black Benjamin Hillyard Kent Fairbourn

  2. Project Scope • Find heat loss from windows in Clyde Building lobby • Determine financial loss due to heat loss

  3. Window Setup • Double paned • Dimensions: 7 ft x 6.01466 ft x 0.01041666 ft • Gap thickness: 0.041666 ft • Window thickness: 0.061834 ft

  4. Finding h

  5. Problem Schematic

  6. Calculated Heat Loss • Assumptions: • No convection between panes • Gap width equal to 0.5 inches • Free convection • Finding the h values: • Each Nussel number was calculated to find the h value • Determining the heat gain from convection • Using a thermal circuit, heat transfer was calculated • Determining the heat loss from convection • Thermal circuit was used again to find heat transfer

  7. Financial Burden • Using a value of 0.069 dollars per kWh, total cost was figured to be $615.00 per year National Electricity Rates
