achieving HVAC and energy system optimization. This step usually comprises of a
long-range plan that itemizes actions needed to be taken for best return on
investment. Decreasing the load on your building helps the HVAC system function
more efficiently.

- Add extra insulation and tighten the shell of the building. Extra insulation in a building could be a little difficult in certain cases, so it is best to aim towards the exterior shell, particularly doors and windows.
- Installation
of windows that are energy-efficient. This can work very well for buildings
with single pane windows. Double pane windows that have a thermal break are
known to be one of the best ROI.
- Lighting
system upgrade. For maintaining proper levels of lighting, an average
building has 2-3 watts of lighting density per square foot. This is one of
the biggest reasons for load on an HVAC system. Accent lighting are extremely
energy inefficient and must not be used if one wishes to decrease HVAC and
energy costs. Lighting systems that are energy-efficient release less heat
inside conditioned space when compared to older incandescent technology.
- Choose
efficient electronic devices and equipment that have power saver option.
This will assist in decreasing sensible heat gain within a space. Things
to consider are, kitchen equipment, refrigerators and computers.

energy optimization is understanding your system well. Your system is important
for your interior environment. At the same time, it also is a big reason for
your bill. In case you have a unit, which is older than 13 years, it is best
that you decide for an upgrade. Systems that are well maintained have an

times. Make sure you keep a replacement plan handy for the day the unit fails.
