7-2.2
Heating, Ventilating, and Air Conditioning (HVAC). Design the HVAC
system to comply with the recommendations of the American Society of Heating,
Refrigeration and Air Conditioning Engineers (ASHRAE) and to be responsive to the
needs of children. However, the HVAC system must also meet the exceptions provided
in this UFC. Provide air conditioning in all spaces (including kitchen) for all geographic
locations except Iceland.

7-2.2.2
Energy Conservation. Site the building for passive energy conservation,
insulate fully, and design for active solar gain when authorized. Capitalize on day-
lighting to reduce energy use. Incorporate free cooling with economizing cycle HVAC in
mechanical systems. Use renewable energy technologies in facility projects whenever
feasible and cost effective. Consider ground-source heat pumps, high-temperature
solar, geothermal, wind, biomass and bio-gas energy sources. See Section 2-18 for
more information on energy conservation.
7-2.2.3
Heat Generation. I n child accessible areas, select, locate, and protect
heating devices to prevent children from coming in contact with surfaces having
temperatures in excess of 43 degrees C (110 degrees F). Locate heating units that
utilize flame only in the mechanical rooms or other areas where children do not have
access. Vent properly to the outside and supply with sufficient combustion air. Do not
use open fireplaces, portable combustion space heaters, or portable electric heaters as
heat sources. Do not specify equipment that interrupts continuous and flat wall space at
child levels that may accommodate perimeter activity areas.
7-2.2.3.1
For additional comfort in the infant and Pre-toddler activity rooms,
consider utilizing radiant floor heating as a primary or supplemental heating source. Do
