HOTEL BENCHMARKING CASE STUDIES
TESTING HOTEL ENERGY EFFICIENCY
Every day of every year, hundreds of hotels, from boutique operations to large resorts, rely on
significant amounts of electricity and natural gas to service tens of thousands of customers
A series of energy benchmarking case studies just released shows the hotel industry how to

REAL AND PROVEN RESULTS
about good practice.
The hotel energy benchmarking case studies demonstrate real and proven results. They report
on ways to improve energy efficiency—ranging from simple changes, which involve little
or no capital investment, to longer-term improvements that may require some funding.
Many initiatives have quick payback periods.
A sampling of case study results explains how hotels can save thousands of dollars annually
by implementing changes in key service areas, including kitchen catering, pool and spa
heating, water heating, air-conditioning and ventilation, and lighting power.
1. Installing efficient ice makers: capital cost of $6 000, generating annual energy savings
of 230 400 kWH, delivering annual cost savings of $23 040.
2. Installing water efficient shower roses and a temperature setback system: capital cost
of $3 600, generating annual energy savings of 75 035 kWH, delivering annual costs
savings of $14 493.
3. Filling north facing rooms first: capital operating cost of $3 200, generating annual energy
savings of 182 400 kWH, delivering annual costs savings of $16 416.
4. Installing timers on external lighting: capital cost of $360, generating annual energy
savings of 26 280 kWh, delivering annual cost savings of $5 782.
5. Installing timers in hallways: capital cost of $883, generating annual energy savings
of 14 717 kWH, delivering annual costs savings of $5 400.

HOTEL ENERGY BENCHMARKING CASE STUDIES
The case studies were produced by the Commonwealth Energy Efficiency Best Practice
(EEBP) program and the Australian Hotels Association, after studying six major hotels.
Each case study includes benchmark and performance comparisons, a cost-benefit analysis,
annual energy savings, capital costs, annual energy cost savings and return on investment.
FEATURES OF ENERGY BEST PRACTICE HOTELS
The energy benchmarking project concluded that best practice hotels: a) have systems
in place to monitor, record, analyse and report on hot water, gas and electricity use;
b) achieve significant and cost-effective savings by focussing on best practice energy efficiency;
c) incorporate ways to increase energy efficiency into improvements and/or renovations;
and d) continually look for innovative ways to optimise energy performance.
