Fundamentals of Energy in Buildings Undergraduate 4.42J, 2.66J, 1.044J Students from courses 1,2,3,4 and 10Subject Outline  Fundamentals of ± Thermodynamics ± Heat Transfer ± Fluid Flow  Applied to the design and operation of energy efficient buildings  Issues of economics, behavior, environment  Creative design project  Hands on performance measurements (with equipment obtained with MITEI support)Examples of student design projectsDESIGN PROJECT 2 LIGHTING IN ARCHITECTURE STUDIO 7For the purpose of simplicity we selected one particular desk (approxi-mately) right under the desk, and decided to use that as our lighting test zone. We used a Extech HD450 light meter to take readings at the location under different lighting circumstances. The data is shown below: At Night (Fluoroscent Lights only) = 680 Lux During the Day (Fluoroscent Lights only/skywindows closed) = 850 Lux During the Day with straight Glare = 11000 Lux During the Day with straight Glare and White museum Board = 14500 Lux Mezannine with Lights off : 65 Lux Mezannine with Lights on : 628 Lux Image of Extech HD 540 light meter removed due to copyright restrictions.skylights 300mm sunpipesEstimated yearly savings for one studio  $1700 per year savingsSingle Pane: Building 3Plastic Surgery for old buildingsnon-obtrusive to currently inoperable windows discreet scaleable to entire building simple to install and maintain19.2 GJ saved per heating season  Equivalent to 20% of season heat for a single family home in BostonCurrent Situation Windows are efficient Living Room ʹ casement windows Dining Room ʹ double-hung windowsBefore After477 - 479 CommonwealthDining Room Windows Storm Windows Leaky due to wood frames Large and Operable Curved to fit walls of room -expensive to replace 5 inch gap between inner andouter windowsCO2 Leakage through Windows The purpose of our experiment is to evaluate the air leakage through the windows in a controlled environment, by measuring the rate of CO2 flow out of the otherwise sealed room.Outside trim Sash pulleyand cord Top sash Sill Jamb Parting sash Blind stop Interior sash stop Stool Bottom sash Estimated Savings of Caulking and Weather stripping Estimated Heat loss due to old/ leaky windows: 10,348 MJ/windowBy completely eliminating air leaks(ideal case) we can save: $2164/year Image by MIT OpenCourseWare.Experiment Setting: Dining RoomRESULTSMIT OpenCourseWarehttp://ocw.mit.edu 4.42J / 1.044J / 2.45J Fundamentals of Energy in Buildings Fall 2010 For information about citing these materials or our Terms of Use, visit:
