Based on historical record, an increase in the number of homes has correlated with an increase in energy use, including for heating, cooling and appliances. The share of energy used in homes has increased over time. The increase in use of home appliances and electronics, however, could be offset by efficiency gains per unit."

Essential Resources from ASHRAE


Standard 90.2-2018 -- Energy Efficient Design of Low-Rise Residential Buildings (ANSI Approved)

This standard provides minimum requirements for the energy-efficient design of residential buildings, including new dwelling units, new por tions of dwelling units and their systems, and new systems and equipment in existing dwelling units.


Residential Indoor Air Quality Guide: Best Practices for Home Design, Construction, Operation, and Maintenance

Focused solely on single-and multifamily dwellings covered in ASHRAE Standard 62.2, this unique full-color resource provides tools that builders, home designers, and residents can use to ensure excellent IAQ, while considering budget constraints and other functional requirements.


Standard 62.2-2019 -- Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings (ANSI/ASHRAE Approved)

This standard defines the roles of and minimum requirements for mechanical and natural ventilation systems and the building envelope intended to provide acceptable indoor air quality in low-rise residential buildings.


ASHRAE/ICC 700-2015--National Green Building Standard

ASHRAE has partnered with ICC and NAHB to publish a revised third edition of the National Green Building Standard. The 2015 edition incorporates changes that better align the NGBS with the I-codes, expands the application of innovative practices and builds upon years of building and certifying to NGBS.

Standard 55-2017 -- Thermal Environmental Conditions for Human Occupancy

ANSI/ASHRAE Standard 55-2017 defines the range of indoor thermal environmental conditions acceptable to a majority of occupants, but accommodates a variety of design solutions intended to provide comfort and to respect today's imperative for sustainable buildings.


Guideline 24-2015 -- Ventilation and Indoor Air Quality in Low-Rise Residential Buildings

This guideline provides information on how to achieve good IAQ beyond minimum requirements. It provides information relevant to ventilation and IAQ on envelope and system design, material selection, commissioning and installation, and operation and maintenance.
