E.E.S. Economical Energy
Saving system
HOTEL SAMPLE OF
ECONOMICAL ANALYSES
Project Nr. : 357 3 - 6
Name of Hotel :
Place :
Nr. of Guestrooms : 280
1.0 - Introduction
1.1 General
We are glad to introduce the Economical Study ( ES ) for the
installation of our E.E.S. system in the Hotel .
The calculations are based on the data provided by the Hotel
management sent to us by the Questionnaire .
The ( ES ) is based also on the following assumptions which are
experienced during the years with the E.E.S. system installed in
Hotels .
1.2 - Assumptions
It is well known that the E.E.S. is combined out of two parts
which control together the total Hotel Energy consumption .
The Guestrooms Energy
consumption
The Building -
All balance Energy
consumption .
It is quite complicated and nearly impossible to measure the
accurate Energy consumption for these two parts .
Therefore we
have to assume
some figures which
should or may
be quite
close to reality.
The figures are a combined relation between the Hotel average
occupation and the extend of the foreseen Energy consumption .
1.3 - The assumption for Energy saving by and due to the installation of
the E.E.S. System is estimated as following :
For Guestrooms, about
45% Energy saving
.
For Building , about
35% Energy saving
.
1.4 - Situations of Energy consumptions
Herewith are
some situations of
Energy consumptions in
relation
with the Guestrooms occupation .
In order
to obtain logical
results we had
to assume the extend
( Factor ) of Building & Guestrooms Energy consumption for some
situations of the Guestrooms occupancy which influence directly
on the extend of the Building Energy consumption .
The calculations are presented in the Enclosure .
There is not a final definition regarding the division of Energy
consumption between the
Guestrooms and the
Building .
Therefore we prepared two possibilities in which the range
between them would mostly cover the average reality for several
Hotels .
Herewith are the alternatives :
Part of Hotel Alternative 1 Alternative 2
Energy Consumer
Guestrooms 70% 60%
Building 30% 40%
The Hotel owner may chose either of these alternatives , there is
not an exact definition , but the range between the alternatives will
no doubt cover the reality for most of the Hotels .
The return of the investment will also be prepared for both
alternatives .
2.0- Hotel data

Cost & return of
investment for the
E.E.S. System
The cost
of the installed
E.E.S. system ( excluding
rebate- 30,000 CP
by
the
4%/year) . ..167,000 CP
The reason for the decision NOT to include the a / m was made from
a pessimistic point of view , but the Hotel owners should bare in mind
that the a /m rebate & tax depreciation are available.
Alternatives for Return of
the investment : -
For Alternative 1
167,000 (investment) :
107,723 ( yearly saving ) x 12 months =
18,60 months
For Alternative 2
167,000 (investment) : 105,121 ( yearly saving ) x 12 months =
19.06 months
In order to overcome unforeseen factors and to base the decision on
pessimistic expectations ( from the owners point of view )
EVEN WHEN IT IS NOT EXPECTED !!
We advise
the Hotel owners
to consider the
period for the
investment return upto 3.5 years
( 42
months ) , although the ( ES )
proves that the
expected return period
is only about
19 months
( excluding Rebate 30,000 CP & Tax Depreciation 4% / year !! )
Even by such a pessimistic assumption , the return of investment may reach a heavy return of 55 ( the calculated result within 20 month) 30 % ( within the assumption of 3.5 years ) per year ,
excluding the Rebate by the CEA and Tax depreciation which was not included in the calculations !!
Herewith are specific Situations for the two Alternatives as specified
in para.
