T31.2 CT Energy Efficiency

What is the purpose of building orientation in passive solar design?

• To increase the cost of construction

• To catch winter sunshine and reduce summer sunshine

• To make the building look aesthetically pleasing

• To increase the number of windows

In warmer climates, what type of building materials are preferred for passive solar design?

• Heavy materials with high thermal mass

• Lightweight materials that reduce thermal mass

• Transparent materials

• Reflective materials

What is the recommended size of windows on the southern side of a building in southern latitudes?

• Large windows

• Small windows

• No windows

• Skylights

How can installation help in passive solar design?

• By increasing the number of rooms

• By reducing the loss of heat in cooler weather and heat gain in warmer weather

• By adding more windows

• By using more expensive materials

What is the role of ventilation in warmer climates according to passive solar design principles?

• To increase the humidity inside the building

• To help clean the heat that builds up during the day and provide a comfortable temperature for sleeping at night

• To reduce the number of windows

• To increase the cost of the building

How can shading be effectively used in cooler climates according to passive solar design?

• By positioning the building to avoid overshadowing by neighboring buildings in winter

• By increasing the number of windows

• By using transparent materials

• By reducing the number of trees around the building

What is the ideal orientation for living areas in a building located in Canberra to achieve energy efficiency?

• Southern orientation

• Eastern orientation

• Northern orientation

• Western orientation

How does a concrete floor slab contribute to energy efficiency in a building?

• By increasing the building's height

• By providing thermal mass

• By reducing the building's weight

• By improving the building's aesthetics

What kind of SHGC and U-values would be best for the glazing in a building to achieve energy efficiency?

• High SHGC and high U-values

• Low SHGC and high U-values

• High SHGC and low U-values

• Low SHGC and low U-values

Why is the southern window designed to be smaller than the northern window in an energy-efficient building?

• To reduce heat loss

• To increase natural light

• To improve ventilation

• To enhance the view
