TECHNICAL FEATURE
the no setback approach may even be an effective way
to maintain comfort conditions without costly and
disruptive infrastructure replacements. Lastly, for
buildings with electric heat, the improved morning
warm-up strategies may reduce winter demand charges.
In areas where time-of-use utility tariffs have morning
peak periods in the winter (of which there will be
more in the future as more buildings are electrified),
improved morning warm-up strategies have the
opportunity to reduce both energy and demand charges
and reduce strain on electrical grids.
Future study should examine how different warm-up
strategies may better achieve varying objectives,
whether minimizing energy cost, peak heating load,
peak electrical demand or marginal carbon emissions
and consider suggesting revisions to Guideline 36.
