What is CHENACT?
• CHENACT is a CHTA project financed by :• IDB, GTZ, CDE, UNEP, BL&P, Government
of Barbados, BHTA• It is implemented via CTO by CHTA/CAST• It runs April 2009 to December 2010.
CHENACT04/19/2023 Loreto Duffy-Mayers - CHENACT Project Manager
Objective of CHENACT
To improve the competitiveness of small and medium sized hotels (<400 rooms) in the
Caribbean Region through improved use of energy with the emphasis on Renewable Energy
and Micro-Generation The Pilot project is in Barbados
The beneficiaries are CHTA member hotels
CHENACT04/19/2023
Why CHENACT?Hotels sell Rooms, Food and DrinkBack of House issues in the BackgroundLack of Technical Staff Lack of knowledge of Technology “ Get the place open and making money”Disconnect between utility bills and the costs attached to
that utilityLack of attention to Utility costs until recently, sometimes
cost more than Staff

CHENACT Assistance to Hotels
• Detailed energy audits in 30 hotels in Barbados • Walk Throughs assessments in 35 hotels in
Barbados• Detailed audits in 18 hotels in the OECS• Detailed audits in 5 hotels in the Greater
Caribbean Region• ODS audits in all
CHENACT04/19/2023 Loreto Duffy-Mayers - CHENACT Project Manager
Benefits to the Industry
• More efficient energy use in the Caribbean Hotel Sector
• Reduced energy costs to hotels • Increased competitiveness in the hotel sector
through lower Operating Costs• Increased use of Renewable Energies• Positive Environmental Impacts such as
reduction of GHG’s and ODS
CHENACT04/19/2023 Loreto Duffy-Mayers - CHENACT Project Manager
Benefits to the Industry
• Positive Environmental footprint will attract more environmentally aware consumers, incl. Tour Operators, i.e. Virgin
• Additional revenue may be generated from the sale of carbon emission reduction credits for CHTA
CHENACT04/19/2023 Loreto Duffy-Mayers - CHENACT Project Manager
Benefits to Participating Hotels• Comprehensive report on energy usage in
the hotel will be produced• Analysis of where energy (and Water) is
being used and where wastage is occurring• Recommendations on operational or
technological changes required to maximize efficiency
• Will complement or enhance Green certification process, ie Green Globe, ISO etc
• A communication strategy will market the project and the participants
CHENACT04/19/2023 Loreto Duffy-Mayers - CHENACT Project Manager
Data to be supplied by hotels
A comprehensive pre-audit questionnaire including:
Utility usage for the last 2 years for Electrical Energy LPG / Natural Gas Diesel Fuel Water
Occupancy rates for the last 2 years by Guest Nights Room Nights Conference Attendance, if applicable
CHENACT04/19/2023
Major Benefit to 3 hotels3 hotels will be selected to participate in
Demonstration projects. Approximately $40,000 worth of RE equipment
will be installed in each of the selected hotelsThe hotels will be selected on the basis of the
results of the Energy Audits and with the assistance of the BL&P.
The first 20 hotels to sign up for the detailed energy audits will be the ones considered

Criteria for selection Be sufficiently interested to either match our investment or pay a portion of the cost of
the installation,Be willing to allow others to view the installation and promote itAlready have the technical capability to manage and maintain the installation or which
indicate a willingness to invest in the training of their staff to do so.Be willing to place the information and tracking system on their website for public
information.Have already proven efforts at improving energy and water efficiency Not undergoing extensive building works which would delay the implementation of the
Demonstration ProjectDifferent sizes Small , Medium and LargeBe financially viable and which can be expected to be around for the duration of the
demo models (20)Hotel must have at least 300sq.ft.of south facing roof space no more than 200ft. from
the nearest breaker panel.Loreto Duffy-Mayers - CHENACT Project Manager

Findings to dateAll hotels have water leaks, some could reduce their water
bills by 30-50% if they repaired leaks, One hotel reported a potential saving of > US$250,000
Maintenance is VERY POOR in general, electrical circuits overloaded, solar panels broken, tanks leaking, A/C condensers placed in soil and grass, roofs damaged – unsuitable for PV systems, roofs inaccessible, old kitchen and laundry equipment etc.
Most have solar water heating with either electrical or gas backup, but many do not work and in some cases the hotels are not aware that they do not work!!
Loreto Duffy-Mayers - CHENACT Project Manager
CHENACT04/19/2023
ContinuedThe inspection of the SWH system indicates in many Hotels
shows the use of electrical backup elements in storage tanks and causes the storage tank to perform exactly like an electrical water heating system
Many of the hotels are reading meters but there is little analysis and little knowledge of baselines, benchmarks etc
Many have installed CFL’s but they didn't work – wrong specs etc, now reluctant to spend again!
Many appear to prefer to upgrade rooms rather than spend on “back of house issues”

Initial audit reports indicate significant opportunities for energy efficient savings in the hotel sector
Average potential electricity savings near 40% of total hotel’s consumption Most savings are related to:
1) Retrofit of present mini split unit systems to high efficient AC systems (such as inverter type variable refrigerant volume (VRV) system ) with heat recovery for supplying hot water also.
2) Installation of high efficient lighting systems. Average total paid back period around 2.5 years Total investment costs between US$200,000 and US$550,000 depending on property size
