Condominiums vary in size, service lives, and materials used. These dwellings have a broad impact on the environment andavailable countermeasures also run across a wide range. Therefore, we have incorporated three core concepts into the Brillia series:
Think Green, Think Lifestyle, and Think Future.
I Think Green – 		Green & Cool residential spaces:
Setting up green spaces acts as a heat island countermeasure and brings about a rich natural environment 		
friendly to the ecosystem.

II Think Lifestyle – Introduction of high-efficiency, green residential equipment:High-efficiency equipment comfortably saves energy and contributes to disaster prevention in case of an emergency.
III Think Future –Eco Life Cycle Improvement Plan for Energy and Greenery:
Resident participation in operation and management as well as community development will continue in a cyclewith concepts I and II, above.
