Answer: c) A roof that reflects more sunlight and absorbs less heat
Explanation: Cool roofs are designed with materials that reflect more sunlight and absorb less heat, thus reducing the building’s cooling load and contributing to lower energy consumption.
Q: What does the term “Integrated Design Process” (IDP) refer to in green building?
a) Designing in isolated phases with minimal collaboration
b) A holistic approach that involves collaboration among all stakeholders from the early stages of the project
c) A design process that focuses solely on aesthetics
d) Excluding sustainability from the design process
Answer: b) A holistic approach that involves collaboration among all stakeholders from the early stages of the project
Explanation: The Integrated Design Process promotes collaboration among architects, engineers, contractors, and clients from the outset to ensure that sustainability is embedded in all aspects of the project.
Q: In terms of energy efficiency, what does a “Building Envelope” refer to?
a) The heating and cooling systems inside the building
b) The materials used in the interior design
c) The exterior components of a building, including walls, windows, and roofs, that separate indoor and outdoor environments
d) The building’s plumbing system
Answer: c) The exterior components of a building, including walls, windows, and roofs, that separate indoor and outdoor environments
Explanation: The building envelope includes walls, roofs, windows, and doors, which act as a barrier between the indoor and outdoor environments and significantly impact a building’s energy efficiency.
Q: What is the function of a “Light Shelf” in building design?
a) To absorb heat
b) To block all natural light
c) To reflect natural light deeper into a building
d) To increase artificial lighting requirements
Answer: c) To reflect natural light deeper into a building
Explanation: A light shelf is a horizontal surface positioned inside or outside a window that reflects sunlight deeper into a building, enhancing daylighting and reducing the need for artificial lighting.
Q: What is the key purpose of “Energy Star” certification for buildings?
a) To certify buildings for indoor air quality only
b) To certify buildings that use renewable energy exclusively
c) To recognize buildings that meet strict energy performance standards
d) To focus solely on water efficiency
Answer: c) To recognize buildings that meet strict energy performance standards
Explanation: Energy Star certification is awarded to buildings that meet specific energy performance criteria, helping reduce energy consumption and greenhouse gas emissions.
Q: What is “Stormwater Management” primarily concerned with in green building practices?
a) Increasing runoff into local rivers
b) Managing and reducing stormwater runoff to prevent flooding and pollution
c) Increasing the impervious surfaces around the building
d) Ignoring rainwater collection
Answer: b) Managing and reducing stormwater runoff to prevent flooding and pollution
Explanation: Stormwater management involves techniques that reduce runoff, improve water quality, and prevent flooding, such as permeable pavements, green roofs, and rain gardens.
Q: What is “Daylighting” in the context of green building design?
a) A technique for artificial lighting
b) The use of windows and skylights to allow natural light into a building
c) The reduction of natural light in buildings
d) The installation of electric light fixtures
Answer: b) The use of windows and skylights to allow natural light into a building
Explanation: Daylighting uses windows, skylights, and reflective surfaces to maximize natural light inside a building, reducing the need for artificial lighting.
