New and Notable New LBNL Online Resource: Build Tight, Ventilate
Right Lawrence Berkeley National Laboratory (LBNL) is now
offering a new online resource aimed at improving ventilation in
existing homes in California. This web site provides information
on California’s ventilation requirements, ASHRAE Standard 62.2,
as well as printable documents to help with ventilation training
and equipment. All of this work was done under RESAVE, a
California Energy Commission Public Interest Energy Research
program. The overall goal of this LBNL program is to facilitate
the reduction of energy and peak power spent in homes to
condition air that enters from outdoors. Infiltration—the
uncontrolled exchange of air through leaks and
penetrations—typically accounts for over one-third of total
space-conditioning energy. New homes generally spend the same
fraction of energy on mechanical ventilation. This program aims
to reduce ventilation- and infiltration-related peak load and
energy costs by 25–50%. Learn more about ventilati
