Marriott International
Case Study
‘Green’ Marriott Hotel in London stands to reduce its
carbon emissions by a further 16 per cent following
Power Efficiency assessment.
About Marriott
Marriott International is a leading lodging company with more than 3,400 lodging properties
in 70 countries and territories. Marriott International operates and franchises hotels under the
Marriott, JW Marriott, The Ritz-Carlton, Renaissance, Residence Inn, Courtyard, TownePlace
Suites, Fairfield Inn & Suites, SpringHill Suites and Bulgari brand names.
Marriott-branded hotels in the United Kingdom have successfully reduced carbon emissions
and greenhouse gases collectively by 7.3 percent to earn Carbon Trust Standard certification.
In addition, 25 hotels have achieved Green Tourism Business Scheme (GTBS) certification, a
programme validated by Visit Britain and the International Centre for Responsible Tourism
(ICRT) which assesses energy and water efficiency, waste management and biodiversity.
Challenge
The Chartered Institute of Building Services Engineers (CIBSE) supports the career
development of engineers and has a certification body for the approval of personnel,
specifically Low Carbon Consultants (LCCs) and Low Carbon Energy Assessors (LCEAs). To
aid in the training, certification and ongoing development of these groups, CIBSE wanted to
provide case studies highlighting buildings that had achieved success in the field of energy
and carbon reduction.
To that end, in November 2009, CIBSE created a shortlist of candidate buildings in the UK that
had already been successful in carbon reduction, to undertake a further energy assessment.
The results of the assessment would be used in a case study, illustrating for LCEAs and LCCs,
how similar buildings could operate and achieve carbon, energy and financial savings.
Having already achieved a 7.3 per cent reduction in greenhouse gases, the London Marriott
Marble Arch Hotel, was selected as a case study site for the CIBSE programme. As the Marriott
hotel chain is committed to reducing its fuel and water use by a further 25 percent over the
next ten years, the management team welcomed further analysis of its energy usage at this
hotel and was keen to receive advice on how to meet its ongoing carbon reduction goals.
The Solution
CIBSE selected its most skilled carbon consultancies to participate in this round of
assessments and of these Power Efficiency was appointed to perform the energy assessment
for the London Marriott Marble Arch Hotel.
The Power Efficiency team immediately carried out a site survey of the hotel, identifying
the locations at which energy was being used, in what quantities and to perform which
tasks. Through this process the team was able to highlight good examples of low energy
applications in use at the hotel, including the Versatemp air conditioning, a combined heat
and power system which reduces the amount of imported electricity required. In addition, the
Power Efficiency team was also able to indicate where further efficiencies could be gained.
The Result
Upon completion of the assessment, the Power Efficiency team was able to deliver a full report
along with a proposed action plan that could result in significant energy and cost savings for
the hotel.
The assessment showed that in 2009 the carbon footprint of the hotel was 2,064 tonnes
(2,064,000 kg) of carbon dioxide emissions per year, comprising 1,254 tonnes for electricity
and 810 tonnes for gas.
By following Power Efficiency’s recommended short and medium term improvement
measures, such as the installation of variable speed controls for machinery in the kitchen and
foyer as well as utilising automatic lighting systems in group areas such as the gym, restaurant
and open place offices, the hotel could stand to reduce its carbon dioxide emissions by a
further 16 per cent, and save more than £56,000 per annum in energy costs.
The hotel, keen to further reduce its carbon footprint and take advantage of potential costs
savings, has already implemented some of the measures Power Efficiency proposed.
Bobby Collinson, Managing Director of Power Efficiency, said, “Marriott International is a
leading example of a UK business taking its carbon reduction commitment very seriously. The
Marble Arch site was already meeting key requirements when we assessed it, but with further
action the site stands to reduce its output by an additional 16 per cent. That’s around £56,000
per year, proving that ‘going green’ can be extremely good for business”.
“Our hotels are making improvements that will help move the
United Kingdom closer to achieving its environmental goals.
We are also creating an eco-friendly environment that will help
educate and engage thousands of guests we connect with daily.”
