"The total number of housing units in the U.S. has steadily grown over the last 30 years. 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."

Standard 90.2-2007 -- 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 portions of dwelling units and their systems, and new systems and equipment in existing dwelling units.
Standard 62.2-2013 -- 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
Standard 55-2013 -- Thermal Environmental Conditions for Human Occupancy
ANSI/ASHRAE Standard 55-2013 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 24-2008 -- 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.
