## Award List
■ Chuo Jutaku Co., Ltd. Mind Square Division "P.T.SITE" (Energy saving regional classification: Region 6)
This is a series of ready-built houses that aims to provide value like "Treasures" for living in urban areas. We pursued the creation of a home that will be loved for a long time, combining a sense of openness and functionality even on a limited site, and staying close to the lifestyle of the residents.
All buildings adopt the 2x6 construction method and resin sashes as standard, and clear the performance standards of "Tokyo Zero Emission House Standard B", ensuring excellent energy-saving performance*. In addition, by installing a solar power generation system and storage batteries, we have realized a home that balances a reduction in environmental load with peace of mind in the event of a disaster.
*Insulation performance grade 6 (Average U-value (UA value) of 0.46 or less), Primary energy consumption standard (BEI) of 0.6 or less.
