Saving You Energy By Helping Your Building Breath Easier

Building ventilation systems present huge opportunities for energy savings.  They’re designed to supply sufficient air for the maximum occupancy allowable for a given area. When a room’s full, that’s great.  But when it’s empty, that’s a huge, needless energy waste. 

So buildings are often heated and cooled as if there were high demand for ventilation, even when there’s actually little demand for ventilation. And the energy cost goes through the roof. 

Installing C02 sensors can help assess and regulate the amount of ventilation that’s truly needed – producing a dramatic savings in energy.

Plus, air handling unit dampers are usually set higher than the maximum necessary and additional savings could be realized by making a simple adjustment.

 

A Strategy That’s Just Right

A school building with a huge boiler in the basement may be cranking out heat that never gets to the 3rd or 4th floor, due to lack of insulation around the pipes. 

What you’re left with is a basement that’s unusable because it’s just too hot, and upper floors where students and teachers freeze because it’s far too cold. 

And because the boiler is cranking constantly while still not heating the upper classrooms, the energy bill becomes unnecessarily huge.

Yet just by insulating the pipes, you can often fix the problem – and the environment everywhere is just right. 

This is a medium-cost measure with greater than 40% energy savings, (less than a 2 year pay back)

Just How Cool Is Your Programmable Thermostat
When It Comes To Saving Energy?

Programable Thermostat

We all know programmable thermostats can produce dramatic savings by turning down HVAC systems during unused hours – including throughout the night when a building is vacant.

But deploying programmable thermostats typically means the clock dictates when the heat or AC kicks on.  In very cold winter days or hot summer days, the thermostat turns on prior to the start of the day for a pre-set period which is presumed to allow sufficient time to heat or cool the building – regardless of the outside temperature. 

So, when people do arrive, the building may not have reached the right temperature and the system may still be working to keep people happy -- or the building may have been sufficiently heated or cooled far earlier than was needed.  In the latter case, there’s wasted energy.  In the earlier case, people are uncomfortable and less productive. 

The solution: adaptive control is self correcting software that slides the starting time (morning) backwards as it makes a mistake in cold weather and forward as it gets warmer. The reverse would occur for air conditioning. Adaptive controls assess outdoor and indoor air and start the system just as needed.  You be the judge: how cool is that.
