Module 2: Energy-Efficient Building Envelopes
Energy-Efficient Building Envelopes
Knowledge check
Q1. What is the primary function of a building envelope?
- A. To provide structural support for upper floors
- B. To separate the interior environment from the exterior climate ✓
- C. To generate electricity from sunlight
- D. To store rainwater for building use
Why: The building envelope, including walls, roof, windows, and floors, forms the barrier that separates conditioned interior spaces from outdoor conditions such as heat, cold, wind, moisture, and noise. Its performance largely determines how much energy a building needs for heating and cooling.
Q2. What does the R-value of an insulation material measure?
- A. Its resistance to fire spread
- B. Its resistance to heat flow ✓
- C. Its resistance to water vapor
- D. Its resistance to compression
Why: R-value measures thermal resistance, or how effectively a material slows the flow of heat. A higher R-value indicates better insulating performance. It is a key metric when comparing insulation products for energy-efficient envelopes.
Q3. What is thermal bridging in a building envelope?
- A. A bridge built across a river to supply construction materials
- B. A path through the envelope where heat flows easily, bypassing insulation ✓
- C. A connection between two separate buildings sharing a heating system
- D. A decorative feature that reflects sunlight onto the facade
Why: Thermal bridges occur where conductive materials such as steel studs, concrete slab edges, or window frames pierce the insulation layer. Heat takes the path of least resistance through these points, increasing energy loss and sometimes causing condensation and mold.
Q4. Why is air sealing important in energy-efficient building envelopes?
- A. It prevents birds and insects from entering the building
- B. It reduces uncontrolled air leakage that wastes heated or cooled air ✓
- C. It increases the structural strength of exterior walls
- D. It allows fresh air to be drawn in without any filtration
Why: Uncontrolled air leakage through gaps and cracks can account for a large share of a building's heating and cooling losses. Continuous air sealing, combined with controlled mechanical ventilation, keeps conditioned air inside and improves comfort and energy performance.
Q5. Which of the following best describes a low-emissivity (low-E) window coating?
- A. A coating that makes the glass completely opaque for privacy
- B. A thin metallic layer that reflects infrared heat while allowing visible light through ✓
- C. A waterproof layer that prevents condensation on the outside of the glass
- D. A paint applied to window frames to reduce sound transmission
Why: Low-E coatings are microscopically thin metal or metal-oxide layers that reflect long-wave infrared radiation, keeping heat indoors in winter or outdoors in summer. They still transmit most visible light, so windows remain bright while reducing heat transfer.

Passive Heating and Cooling Strategies
Knowledge check
Q1. Which passive strategy involves placing the largest windows on the equator-facing side of a building to capture winter sunlight?
- A. Thermal mass placement
- B. Solar orientation ✓
- C. Natural ventilation
- D. Evaporative cooling
Why: Solar orientation positions the building and its glazing to maximize useful solar gain in winter while limiting excess exposure in summer. In the Northern Hemisphere, this typically means the largest glazing faces south.
Q2. What is the main purpose of thermal mass in a passively heated building?
- A. To block all incoming sunlight
- B. To absorb heat during the day and release it slowly at night ✓
- C. To increase air leakage for ventilation
- D. To reflect infrared radiation outward
Why: Thermal mass materials such as concrete, stone, or brick absorb solar heat during the day and release it gradually as temperatures drop, smoothing out indoor temperature swings.
Q3. Which cooling strategy uses the natural tendency of hot air to rise to draw cooler air in at lower levels?
- A. Stack ventilation ✓
- B. Radiant floor heating
- C. Super-insulation
- D. Desiccant dehumidification
Why: Stack ventilation exploits the buoyancy of warm air. Openings at low and high levels create a pressure difference, pulling cooler outside air in at the bottom and expelling warm air at the top.
Q4. What is the function of an overhang or brise-soleil on a south-facing window in the Northern Hemisphere?
- A. To increase heat loss in winter
- B. To block high summer sun while allowing lower winter sun to enter ✓
- C. To prevent daylight from entering the room
- D. To channel wind into the building
Why: Because the sun is higher in summer and lower in winter, a properly sized overhang shades the window when the sun is high and lets low-angle winter sunlight reach the interior for passive heating.
Q5. Which term describes the cooling effect produced when water evaporates into dry air?
- A. Conduction
- B. Convection
- C. Evaporative cooling ✓
- D. Infiltration
Why: Evaporative cooling occurs when water absorbs heat from the surrounding air as it changes from liquid to vapor, lowering the air temperature. It is effective in hot, dry climates.

- A. Measuring the wind speed at a turbine site
- B. A billing arrangement where excess electricity sent to the grid is credited against electricity drawn from it ✓
- C. Installing a mesh of sensors across a building facade
- D. Calculating the total roof area available for panels
Why: Net metering allows building owners who generate more electricity than they use to feed the surplus into the grid and receive credits that offset future consumption.
Q4. Why is building orientation important when integrating solar panels in the Northern Hemisphere?
- A. Panels work only when facing north to avoid glare
- B. Panels facing south typically receive the most solar irradiance throughout the year ✓
- C. Orientation has no effect on solar panel output
- D. Panels must face east to capture morning wind
Why: In the Northern Hemisphere, south-facing surfaces receive the greatest and most consistent sunlight over the course of the year, maximizing energy yield from photovoltaic systems.
Q5. What is a key advantage of integrating renewable energy systems during the initial design phase of a building rather than retrofitting later?
- A. Retrofitting is always cheaper than initial design
- B. Early integration allows designers to optimize orientation, structure, and space for energy systems ✓
- C. Renewable systems cannot be added to existing buildings
- D. Design-phase integration eliminates the need for electrical wiring
Why: Integrating renewables early enables coordinated decisions on building form, roof structure, orientation, and mechanical layout, which typically yields better performance and lower overall cost than adding systems afterward.
