WARM UP #3A: WINDOW ORIENTATION


OBJECTIVES: In this warm up you will

Learn about Energy Scheming:

• enter sun angle dependent shading devices
  
• rule of thumb parameter setting
  
  

Learn about energy:

• effect of orientation on solar radiation gain
  
• the performance of various shade types
  
• effect of window size and placement on ventilation
  
• the effect of sun position on radiation gain
  
• the effect of night insulation on heat loss
  
  

Learn about architectural design implications:

• the role of shading devices in facade composition (SWL #65, #66, #68)
  
• contrasts and similarities in building and glazing orientation (SWL #31, #33, #34, #35)
  
• glazing area and facade composition (SWL #41, #58, #60, #63)
  
• plan openness and cross ventilation (SWL #32, #63, #64)
  
  
  

PROCEDURE:
1) Resize the Netscape window to a 2" wide narrow strip on the right hand side of the monitor.







2) In this warm up you will modify a file created in Warm Up
3 Intro. Open Energy Scheming by double clicking the folder and application icon, then open the file (your last name) - Bldg 1 South 100.


3) Arrange the Energy Scheming window and the Netscape window like this.




4) Under the file menu, choose Save Building File As.... Save the file as "(your last name) - Bldg. 1 S & W 100".




5) Select the take off layer and create a west elevation with 100 sf (within a square foot or two) of double pane fixed glazing with no internal or external shading. Close spec. Save.




6) Select Graphic report from the View menu. Set the floating palette as shown.



7) Let Energy Scheming calculate (click on the calculator button. Print the Energy Report from the menu with the settings as shown.

Questions

Please answer the following questions using the graphic reports:
Note: Questions with may have more than one correct answer.

8) The peak heat gain occurs between 12-2 pm for all days in the South 100 file and from 3-5 pm in the S&W 100 file. What causes this shift in peak gain?
