Mary Ann is right on.......I am not sure how old the space heating/
cooling system at Grafton Public Schools. If the boilers produce steam
v/s hot water for space heating there is potential for energy savings.
If the boilers burn #4 or #6 grade oil there is potential for energy
savings by going to #2 oil, even more by converting to duel fuel and
burn gas when oil price goes higher. If the lighting system uses T12
(fat tubes) with magnetic ballasts then there is ton of energy savings
by going to slim tubes (T8) with electronic ballasts. There is ton of
money we can save by intoducing an enegy management system (Direct
Digital Control) if there is none in place. All depends on how old the
building envelope is and how much is the current energy costs is.
There are many programs out there where by the town's energy dept can
hire eneregy services companies (ESCOs) to do energy study, just like
the feasibility study we are undertaking (but no state funding unless
it is a state college or university). The energy dept should consider
issuing an RFP in getting into a performance contracting whereby you
can save hundereds and thousands of dollars over 10-15 years term
contract with the selected ESCO. The town would arrange funding by
borrowing money just like the mortgage, but there is no cost to the
town or the tax payers because the energy cost savings $ each year
would pay for the loan, typically a payback of 10 years, after which
the savings is all ours going forward. The capacity forward by Solar
back to grid, there is no such thing yet, unless you have a
cogeneration plant wherby you produce steam as well as electricy more
than the facility demands. You have to have interconnect agreement to
achieve this. Solar is typically to cutdown/offset the electrical
usage and not to sell, unless you have a huge public school district
such as Boston.
