A.3 Hotel Installs Water-Efficient Sanitary Fixtures
The Holiday Inn estimates that it saves approximately $35,000 each year in water
and sewer bills from reducing its water use. Because much of the water saved is hot
water, the hotel also saves energy from these upgrades. Although the Holiday Inn
does not currently measure this energy savings, based upon typical hot water use
from showerheads and faucets, the hotel likely saves an estimated 330,000 kilowatt
hours of electricity and an additional $33,000 per year in energy savings, for more
than $68,000 in total savings each year.
According to SAWS, the utility spent approximately $100,000 retrofitting the 397
hotel guestroom bathrooms, which would have resulted in a payback period of less
than two years, had the hotel paid for the upgrades. The hotel has also reported that
it no longer receives calls for maintenance of the new fixtures or fittings, compared
to the one to two calls received each day in the past.
