BURNING MONEY
You probably have a Steam system with radiators or a Hydronic system with baseboards.
Maybe a single building thermostat or individual unit thermostats and zone valves.
If you have a central boiler supplying all the units chances are likely that you are overheating the building.
The first clue? High fuel bills.
The confirmation? The drive-by.
We have been in buildings seeing the tenants in shorts, t-shirts, and barefeet while the outside temperature is in the single digits. And open windows of course, maybe a fan, sometimes AC.
80, 90, even 100º inside. The law says 65º, most owner/managers would be thrilled with 70º. For every degree you can reduce you save 3%.
In the meantime, every degree above 70º you are wasting 3%. Ouch...
That budget line item should be in bold.
ADDENDUM
This building owner installed JEMS® and reduced the heating bill 46%
