(a) True

(b) False

This question was addressed to me by my school teacher while I was bunking the class.

I would like to ask this question from Orientation of Building and House Planning topic in chapter Planning of Building and Colony of Civil Engineering Drawing

Answer 1

Right answer is (a) True

For explanation: It allows standard eaves overhangs to admit winter sun to heat the building and exclude summer sun with no effort from the occupants and no additional cost.

Poor orientation can exclude winter sun as well as cause overheating in summer by allowing low angle east or west sun to strike glass surfaces, creating a greenhouse effect where it’s not required. Choose a house that has good orientation or can be easily adapted for better orientation.
