Project Examples

Optimal window Orientation for Passive Solar Housing in Peru

Course: 22.521 Solar Fundamentals
Semester: Fall 2008
Instructor: John Duffy
Partner: Village Empowerment Inc., Village of MAlvas, Peru.

Windows for a solar home were designed for application in Cochapeti, Peru and the surrounding villages, like Malvas. Hourly global irradiation data was averaged to obtain hourly data for a representative day of each month. This data was used to determine the beam, diffuse, and reflected irradiation incident on the North-, East-, South-, West-, and horizontal- facing walls of the home. The location of the windows on the house was chosen based on the horizontal skylight and which walls received the most irradiation during the day
