大岡先生は、21 KOMCEEの地下水・地下熱を利用した冷暖房システム構築を担当されました。
What is most important in zero-energy buildings is to “control” the entire building. With sensors and operation systems, the amount of energy consumption is kept at minimum. In addition to the design of the building, changing attitudes of people towards the environment is also important to seek ZEB.
Prof. Ooka has participated in constructing the 21 KOMCEE where this seminar is held. This building was designed in an attempt to accomplish ZEB by 2030 and it has some experimental tricks and devices.
One of these devices is to utilize groundwater for air conditioning. It pumps up groundwater deep under the building and the water will efficiently cool down or warm the ceilings that will subsequently modulate ambient temperature through radiation. The Radiation air conditioning system heats not the air around humans but human body directly, thus it can save energy for fanning the air. Other than that, there are many systems to seek ZEB in this building. For example, movable louvers automatically following the sun’s movement help to use sunlight and warmth more efficiently.
