Sustainable Building
Energy Display

What does it do?
The purpose of this product is to address
the following two problems:
- Tenants currently have little or no immediate
feedback on how their behavior effects
the
energy usage in their buildings.
-
Building owners and managers have
no
easy
way to compare the performance of their
buildings
with others.
It attempts to do this by showing the
building's
electrical energy at this moment, for
two
weeks, and for a year.

The following table describes the three parts
of the display:

| Purpose |
To give tenants immediate (within a few seconds)
feedback on changes in their electrical energy
consumption, to encourage experimentation.
To allow tenants to recognize when their
building is consuming energy faster (higher
power) than intended, i.e. above the target
range, at a particular moment. |
To allow tentants and building managers to
compare energy usage weekday to weekend,
this Monday to last Monday, etc.
To allow tentants to recognize when their
building is using more energy than intended
on a particular day of the week. |
To allow building owners and managers to
compare their building's energy efficiency
with other buildings.
The hope is that this sort of data will eventually
encourage competition among building owners and therefore save
energy. |
The green arcs and bars show the power, energy,
and efficiency target ranges. The building
manager sets the efficiency target arc in
the right-hand dial to match local, national,
or international guidelines. The software
automatically adjusts the size of the arc
in the left-hand dial and the sizes of the
green bars in the center charts.
