1. Which Colorado requirement most directly governs the energy
performance of buildings when a municipality has adopted and
enforces building codes?
A. The municipality may ignore energy efficiency requirements if the
project is privately funded
B. The municipality must adopt and enforce an applicable energy code for
covered construction and major renovations
C. Only state-owned buildings are subject to energy codes
D. Energy codes apply only to electrical installations
B. The municipality must adopt and enforce an applicable energy code
for covered construction and major renovations
Colorado law requires municipalities that adopt and enforce building
codes to adopt and enforce an energy code applicable to construction
and major renovations or additions within their jurisdiction.
2. Under Colorado's current statutory framework, municipalities
updating building codes on or after July 1, 2026, must adopt an
, energy code achieving performance equivalent or better than what
type of model code?
A. A plumbing conservation code
B. A low energy and carbon code
C. A fire protection code
D. A residential electrical code
B. A low energy and carbon code
Beginning with building-code updates on or after July 1, 2026, Colorado
law requires the applicable energy code to achieve equivalent or better
energy and carbon-emissions performance than the model low energy
and carbon code developed through the state's energy code process.
3. What is the primary purpose of an energy-efficiency contractor's
building-envelope work?
A. To increase uncontrolled air movement through the structure
B. To reduce unwanted heat transfer and air leakage
C. To increase electrical demand
D. To eliminate the need for mechanical ventilation
B. To reduce unwanted heat transfer and air leakage
A properly designed and installed building envelope reduces conductive,
convective, and uncontrolled air-transfer losses, thereby reducing
heating and cooling loads while improving occupant comfort.
4. Which measurement is most commonly used to express the thermal
resistance of insulation?
,A. U-factor
B. SHGC
C. R-value
D. COP
C. R-value
R-value measures resistance to heat flow, with higher values generally
indicating greater resistance to conductive heat transfer through an
insulation material.
5. What does a lower U-factor for a window generally indicate?
A. Greater heat transfer through the window
B. Better insulating performance
C. Greater solar heat gain
D. Higher air leakage
B. Better insulating performance
U-factor represents the rate of heat transfer through a window
assembly, so a lower U-factor generally indicates better resistance to
conductive heat flow.
6. What does solar heat gain coefficient (SHGC) describe?
A. The percentage of indoor air exhausted by a fan
B. The rate of electrical resistance in a window
C. The fraction of incident solar radiation admitted through a window
D. The thermal resistance of wall insulation
C. The fraction of incident solar radiation admitted through a window
, SHGC describes how much solar radiation enters a building through
glazing, making it an important factor in cooling-load and passive-solar
calculations.
7. Why is continuous air sealing important in an energy-efficient
building?
A. It increases uncontrolled infiltration
B. It reduces unwanted air leakage through the building envelope
C. It eliminates the requirement for insulation
D. It increases duct leakage
B. It reduces unwanted air leakage through the building envelope
Air sealing limits uncontrolled infiltration and exfiltration, reducing
energy losses and helping HVAC systems operate more efficiently.
8. Which condition is most likely to create a thermal bridge?
A. Continuous exterior insulation
B. A properly sealed insulated wall cavity
C. A metal structural member passing through an insulated assembly
D. A continuous air barrier
C. A metal structural member passing through an insulated assembly
Metal conducts heat much more readily than insulation, so structural
members that interrupt insulated assemblies can create thermal bridges
and localized heat loss.
9. What is the principal purpose of a blower-door test?
