QUESTIONS AND ANSWERS WITH
SOLUTIONS 2024
Energy Standards - ANSWER Describes how buildings should be constructed to save energy cost-
effectively. They are published by national organizations such as the American Society of Heating,
Refrigerating, and Air-Conditioning Engineers (ASHRAE)
Energy Codes - ANSWER Specify how buildings MUST be constructed or perform, and are written in
mandatory, enforceable language.
(States, Provinces, or local govs adopt and enforce energy codes for their jurisdiction)
ASHRAE 90.1 - ANSWER Voluntary consensus standard for energy efficient design of new commercial
buildings.
Set minimum requirements for energy efficient design of new buildings to be constructed operate and
maintained efficiently without compromising comfort or productivity of occupants.
Provide criteria for such design, and method to determine compliance.
Provide sound guidance for energy efficient design.
High-rise Commercial building or High-rise residential
ASHRAE 90.2 - ANSWER Energy standards for low-rise building usually less than 3 stories
International Energy Conservation Coded - ANSWER Model energy code that makes allowances for
different climate zones
It is written in mandatory, enforceable language, so state and local jurisdictions can easily adopt the
model as their energy code.
ASHRAE 62-2007 - ANSWER -Ventilation for acceptable Air Quality
-Specifies minimum ventilation rates and IAW that will be acceptable to human occupants and are
intended to minimize the potential for health effects
