Each of the Charts on this page show the
end-use data averages per each Climate
Region. The Climate Regions include Blue as
the coldest Region, with Green also cold, but
less so. Yellow has mild winters and Red has
little seasonal change. The data has been
organized into different end-use combinations
that are identified in these charts as Group 1,
Group 2, and Group 3.
Group 1 data clearly
indicates that the Red, Green and Yellow
Regions expend most of their energy use in
climate control for the building. The colder
regions spend most of their energy heating the
building.
The Yellow Region spend more
energy on cooling the building.
In the Red
Region, the majority of energy shifts to the plug
load and equipment category. Group 2 data
combines building climate control into a single
category of heating/cooling since the design
approaches (including building envelope and
load reduction strategies) are interrelated for
these two systems. In this group the numbers
for lighting and plug loads and equipment were
also
combined
since
the
load
reduction
strategies for design of these systems are also
interrelated
(daylighting,
specification
of
efficient components, controls to support load
reductions). Group 3 data further consolidates
the end-use numbers. In this configuration, the
Fans/Pumps category has been added to the
Heating/Cooling
category
because
in
a
commercial application the fans and pumps
are being utilized in the heating and cooling
systems. Group 3 shows that approximately
half of energy is utilized
to support climate
control
and
the
other
half
for
activity
functionalism.
Energy reduction strategies
should balance climate control solutions with
activities support solutions .
For example,
design of the building envelope should strike a
balance between providing adequate insulation
while
also
contributing
daylighting.
In
comparing the charts for Group 1 and Group 3,
it is apparent that the Red and Yellow Climate
Regions would benefit from strategies which
would lower plug load and equipment demands
such as occupancy sensors and controls
because they would also reduce internal heat
