New World Millennium Hong Kong Hotel

Advanced MOL Service for Better Hotel Energy Management

New World Millennium Hong Kong Hotel not only offers quality hospitality services, but also seeks to apply energy-saving solutions that benefit the environment.

Inspired by the introduction of the Meter Online (MOL) service at CLP’s Green Building Symposium, New World Millennium Hong Kong Hotel applied for the service, a simple and convenient tool to access the latest load profile data provided by CLP.

A new upgraded version of MOL was introduced in 2015. The hotel started to utilize the new version, MOL 3.0 which has features including a 9-Day consumption forecast and precise forecast on the time of peak demand. Based on the humidity and temperature, MOL 3.0 predicts the hotel’s peak demand that would occur during 12 noon and 2 pm and sends out an email alert. The hotel would then take prompt action such as increasing the chilled water temperature of air conditioning system by 0.5°C and optimising the operation of Primary Air Units (PAUs). The hotel can then achieve energy saving without additional capital and manpower investment.

After implementing MOL 3.0, the hotel successfully reduced 5% energy consumption from 2014 to 2015. Despite the slight adjustment on the average temperature of the hotel, the hotel service quality was not affected. The enhanced MOL 3.0 service also raised staff’s awareness of energy management and energy usage.

Summer is the peak season for electricity consumption, if you want to better manage your energy consumption, please contact your CLP Account Managers or send email to meteronline@clp.com.hk to subscribe for the MOL 3.0 service. Your environment-friendly contribution always counts.

Silvermine Beach Resort

A Safer and Eco-friendlier

Sitting on the beautiful Silvermine Beach in Mui Wo, Silvermine Beach Resort is a secluded place for holiday-goers and nature-lovers. Since the change of its ownership, the Resort has started intense renovation and one of its major goals is to adopt facilities that complement its natural environment.

To support the Resort's intention of using more environmentally friendly equipment, CLP helped replace the old chiller systems with new heat recovery technology. The heat recovery technology generates hot water without using additional electricity and has replaced two sets of diesel boilers that have been providing hot water for 128 guestrooms since 1984.

As a result of the upgrade, the Resort has benefited from free hot water supply and improved energy efficiency, and avoided the storage of dangerous and flammable diesel on site.

With CLP's professional advice on energy saving and Energy Efficiency & Conservation applications, the Resort management is in the process of replacing the highly unsafe and flammable sterno cans with electric buffet burners. Guests will rest easy while their kids play in a much safer environment given there is no naked flame on the buffet tables. The new management also replaced CRT television sets with low energy consumption LED/LCD TV sets. The new installations are all in line with the Resort's objective of providing the most natural of setting for holiday makers. You will be able to relax in the knowledge that you are contributing to a much healthier environment and caring for the future of not only the local Mui Wo community but also preserving the natural environment for your kid's future.

Shangri-La Hotel, Guangzhou

Saved Energy Expenses

CLP Energy Services and Technology has helped the Shangri-La Hotel, Guangzhou, saving nearly 50% in heating expenses through retrofitting of the hotel's water heating system. The hotel used to rely on traditional diesel and natural gas boilers. In view of constantly rising fossil fuel costs, the management decided to replace the water heating system for better cost control.

CLP recommended using water generated from the hotel's central air-conditioning system as a heat source and installing a heat pump to recycle the energy for water heating purposes. This solution kills two birds with one stone by alleviating the air-conditioning load and reducing water heating expenses.

Assuming a 50% average occupancy rate, Mr. Goh, Kim Leong, Director of Engineering of Shangri-La Hotel Guangzhou, estimated the new system could save 153.4 tonnes of coal consumption per year and that the hotel's water heating expenses would be reduced from $1.35 million to $610,000.

Long summers in Hong Kong and southern China make heat pumps an ideal solution to save water heating and air-conditioning expenses.
