Cases of Green Key hotels
Since the start of the eco-label Green Key in 1995 the certified companies and hotels have done a lot to improve the environment and to reduce the CO2 emission. They have also saved a lot of money on operating cost and attracted more environmental concerned customers. The Green Key shows that it is possible to create an outstanding experience by combining quality, comfort and environmental responsibility.
In this document you will find a range of some good Green Key cases.
8 different cases:
- Crowne Plaza - The new energy-efficient super hotel with Green Key certification
- Green Key Hotel Marriott Copenhagen inspires the rest of the chain
- Green Key Hotel Sinatur Skarrildhus produces 10% more energy than they use
- The Comwell chains 10 hotels – all certified with Green Key - saved 932.000 tons CO2 in 3 years
- Green Key Hotel Opus with groundwater cooling and biogas production
- Green Key Hotel Savoy reduces the water and energy consumption
- Green Key Hotel Alexandra is CO2 neutral and reuses old classic Danish
- Electric cars and CO2 neutral beers on Bröchner Hotel four Green Key hotels
1. Crowne Plaza - The new energy-efficient super hotel with Green Key certification
Crowne Plaza Copenhagen Towers will set new standards on how future demands for sustainable hotels and workplaces are met - without compromising on quality and comfort.
The Crowne Plaza in Orestad City, Copenhagen, is the first hotel in Denmark run exclusively on energy from renewable energy sources. The CO2-neutral hotel fully complies with both the Danish low energy class II standards and the EU Green Building certification criteria. The hotel facades are covered with solar cells approximately saving the hotel 170,000 kWh pr. year corresponding to electricity consumption of 55 households.
Crowne Plaza Copenhagen Towers extracts its heating and cooling from the groundwater, 100 meters below the surface. The system is very unique as the water used for cooling in the summer is used again for heating in the winter. The groundwater –based cooling and heating system will reduce the energy consumption used to cool and heat by almost 90%.
The environment has been taken in to account in all decisions concerning construction of the hotel from the investment in environmental friendly furniture to the 100 % degradable disposable razor.

2. Green Key hotel Marriott Copenhagen inspires the rest of the chain
Marriott Copenhagen was certified in spring 2009. They have established an Environmental Committee with employees from all departments and headed by the General Manager. This setup insures that all employees are involved in the process and that there is an environmental red line in everything they do.
Marriott has a seawater cooling system, used in the summer season for air-condition and fridges and they are also reducing the energy consumption by using heat generated from chillers in the summer season, to pre-warm potable water.
They use more and more LED light and motions sensors on relevant locations and food waste is collected for biogas-production.
The work with environment on Marriott Copenhagen is inspiring the rest of the Marriott chain and the head quarter, that is now focusing more on improving the environment.

3. Green Key Hotel Sinatur Skarrildhus produces 10 % more energy than they use
Skarrildhus in the middle of Jutland are producing 10 % more energy than they use. In 2008 they had an energy consumption of 1.200.000 kWh (650 tons CO2), but almost 50 % of the energy came from their own windmill and 60 % of the energy came from own woodchip-fire with wood from their own forest. This means that they in 2008 produced 10% (65 tons CO2) more energy than they used.
Skarrildhus is a part of the Sinatur chain with six hotels, where the aim is to reduce the CO2 emission with 25 % within the end of 2012. Two other hotels in the chain - Frederiksdal north of Copenhagen and Gl. Avernäs on Fyn - have a solar heating system, which produce respectively 22233 kWh (12 tons CO2) and 29285 kWh (16 tons CO2).

4. The Comwell chains 10 hotels – all certified with Green Key - saved 932.000 tons CO2 in 3 years
The Comwell chains 10 hotels – all certified with Green Key - saved 932.000 tons CO2 in 3 years
In the past 3 years the Comwell chain has worked hard to reduce their energy consumption and saved 932.000 tons CO2. (15.324 l oil, 255.434 m3 natural gas, 540.364 kWh electricity and 166.332 kWh central heating)
They have achieved the greatest reductions on heating of approx. 3.180.438 kWh, equivalent to the normal consumption of 265 "Danish-family houses" of 100 m² a year.
Electricity savings in the same period has been reduced by 540.364 kWh, equivalent to the electricity consumption of approx. 135 " Danish-family houses" a year.
Comwell are especially working in the areas of motivation of the employees, exchanges of experience and energy management at all hotels.
- Adjustment and changes of the energy facility management: In areas where there have been the greatest reductions, the primarily cause of optimization has been within the adjustment and changes of facility management, summer operations, etc. Two hotels have replaced an older and outdated energy facility with new gas boilers with an efficiency of approx. 96%.
- Involving the employees: The conditions for achieving major reductions are greatly increased with focus on and involvement of operational staff, so that the heating operation is operated optimally. By involving the staff in the project, the conduct changed, thereby ensuring the positive development.
- Electricity: On electricity Comwell have ensured a reduction on pumps and ventilation. There have been several projects underway to implement LED lighting in areas where it is possible. Comwell Middelfart installed LED lighting in the reception area and lobbies. The investment was around. 75.000 DKK (15.000 USD), with a saving per year at 94.000 DKK (18.800 USD) payback time is only 0.8 years. In addition to lower maintenance costs, the longevity increased from 2.000 hours to 30-35.000 hours on light sources.
- Kitchen: Comwell has launched a new energy optimization project on how to create energy reduction in the kitchen. The kitchen area uses a lot of energy for water, heat and electricity.

5. Green Key Hotel Opus with groundwater cooling and biogas production
On Hotel Opus in Horsens all the rooms are cooled down with a groundwater cooling system which uses less energy and therefore saves the emission of 254 tons of CO2 compared to traditional air condition. It saves 424.000 kWh compared to a traditional compressor plant.
All organic waste, including waste from the kitchen and the restaurant, is reused in a biogas, because of a new and special organic waste recovery system. 60 tons of the organic waste produces biogas equivalent of 70.000 kWh (38 tons CO2.)
The two systems mean that Hotel Opus saves energy equivalent to 349 flight trips from Copenhagen to New York.
At the same time the CO2 emission from the hotels is neutralized with buying CO2 allowances from Danish Society for Nature Conservation.
Many plastic products including pencils are produced on biodegradable plastic from 100 % plant starch and Lactic.

6. Green Key hotel Savoy reduces the water and energy consumption
Green Key hotel Savoy reduces the water and energy consumption. Before entering Green Key in the summer 2009 it was demanded that Savoy on Vesterbro had to put water sawing facilities on the showers, taps and toilets, which means an expected reduction of 20 to 30 % equivalent to a reduction of 750.000-1.100.000 liter water every year.
An energy adviser visited the hotel on the 30. September 2009 and found that Savoy has already done a lot to reduce the energy consumption. The adviser only had two suggestions:
- The hotel is already improving the lightning at the elevator changing 85 times 35W halogen spots to 3W LED spots, which means a reduction in 2.233 kWh a year (1,2 tons CO2).
- Next year they expect to shut down half of the light in the room corridors during the night which means a reduction of 2600 kWh every year (1,4 tons CO2)

7. Green Key Hotel Alexandra is CO2 neutral and reuses old classic Danish furniture
Hotel Alexandra has been in the program since the beginning and has done a lot to reduce the environmental impact. Hotel Alexandra is full of elegant and classic Danish furniture that has a high quality and therefore a longer durability. Some of the furniture is bought reused and therefore also has less impact on the environment. The last two years Hotel Alexandra has saved 15 % on electricity.
Hotel Alexandra is CO2-neutral in its total energy consumption of electricity, district heating, and gas as of 1 March 2009 with buying CO2 quotas.

8. Electric cars and CO2 neutral beers on Bröchner Hotel four Green Key hotels
Bröchner Hotels with four hotels in Copenhagen has decided that the chain should be CO2 neutral with effect from 2007. CO2 statements for 2007 were calculated and an equivalent number of CO2 quotas were purchased and destroyed in order to neutralize the CO2 emissions from the hotels’ consumption of electricity and heating in 2007. At the same time they buy power from a climate friendly energy company concerning the supply of CO2 neutral power.
- Heating consumption: Bröchner has changed to new and more climate friendly group heating stations.
- Power consumption: All standard light bulbs are changed to energy saving bulbs as they expire – and as alternative products become available. ‘Switch off the light’ procedures are implemented; this includes PCs that are not in use in the evening and at night. Light sensors are installed in many corridors and basement areas. A LED project will commence for all light sources.
- Bröchner chooses not to install air conditioning as part of a thorough renovation and extension of Hotel Kong Arthur.
- Towels and linen consumption: Linen is now only changed upon departure rather than every 2-3 days as before (unless the guest explicitly requests a linen change).
- A new towel system is completed and is a success. 8 out of 10 guests grasp the concept and only use 1 towel per stay. The system is implemented throughout all hotels.
- Transport and electric cars: Brøchner has invested in electric cars for guests to lease and for internal use. The electric cars (Buddy) are manufactured in Norway and can carry 2-3 persons, drive 50-60 km on one charge and have a maximum speed of 75 km/h. They are therefore primarily suited to city driving.
- All employees are presented with a cycle helmet with the message “Because we use our heads – CO2 neutral hotels”.
- Maize glass: Decomposable disposable glass created from maize is introduced in all bathrooms, except Hotel Fox where reusable plastic cups are used.
- Beer: Bröchner changes their beer range to beer from Nørrebro Bryghus, including their new CO2 neutral beer “Globe Ale”.
