In addition to the snow air conditioning system, there are 2 other eco-friendly ways to cool air. One is the idea of cooling with outside air, which regulates the room temperature provided by natural ventilation through both opening windows and the air supply unit. Another one is the heat absorption system used under the stone-made floor in the atrium. Cool water is circulated through the pipe under the floor, which cools down the stone and eventually cools down air inside the room. Introducing these 3 air ventilation systems derived cold energy from nature, they approach earth-consciously to take advantage of nature of the local weather.

Encircled by the larch grove, “Sea Fountain” is another popular facility approaching CO2 reduction. “Sea Fountain” is operated several times each day according to its schedule. Audience stands around the fountain to enjoy the “sculpture of water” show for 40 minute for each program (15 min. for a short program). Splashing maximum height of 25m water columns from the center of the fountain, the water becomes orderly waves of the sea, to eventually form a huge puddle of water expanded to a diameter of 48m. About 2000 tons of water is used for each program, which the water is stored in the area 300m below ground and is re-used every time for its operation. The recycle use of water play a role to reduce CO2 in the park.

Eco-friendly system at Moerenuma Park

The site for Moerenuma Park is vast. The park covers approximately 189-hactare (467acres), which is equivalent area of 34 Sapporo Domes or 40 Tokyo Domes. You will take 1.5 to 2 hours to walk around the park where is a habitat of a variety of trees, plans and flowers, and animals. When you look on the habitat (biotope) in environmental (ecological) view, you will find an idea “eco biotope” that the plants and trees are playing important role in the CO2 reduction, which will prevent from global warming. According to the “environment map 2008” by Moerenuma Park, the amount plants and trees, including the broadleaf tree such as cherry and the softwood such as larch, absorb CO2 is almost same amount as 1270 people release CO2 emissions for a year.

Prior to G8 Hokkaido Toyako Summit, which will be held on July 7th, “Children’s World Summit for the Environment in Sapporo”, supported by Sapporo city, has been taking place in the Glass Pyramid as a main venue. Also “J8 Junior Summit 2008” by Chitose city will be held on July 8th in Moerenuma Park as one of the venue.

Talking about the snow air conditioning system, Moerenuma Park marked its 6th season for utilizing the system this year. Every year they are assigned “to use whole snow” to make the snow storage empty, for not to produce additional energy for remove leftover snow which will then cause additional CO2 emissions. To be able to use whole snow at the end of every September, checking weather forecast becomes their routine work and they seek to the most effective use of the snow air conditioning system in an eco-friendly view. When thawing season comes, you will feel spring in the air as you see changing colors from all white to various colors of green. People, trees and plans are all breathing. Such an ordinary operation of nature will develop into eco-friendly ideas of creativity. Ecological approach to the environment at Moerenuma Park will be continued in the future.
