one building Starts Providing Product Information for DuPont Styro's "Styrofoam™" Series Insulation Materials on its Energy-saving Review Web Service, Supporting Envelope Performance Review Based on Actual Product Data

one building Inc. (Meguro-ku, Tokyo, hereinafter "one building") has started listing product information for DuPont Styro Co., Ltd.'s (Headquarters: Chiyoda-ku, Tokyo, hereinafter "DuPont Styro") extruded polystyrene foam insulation material "Styrofoam™" on its free "Energy-saving Review Web Service" for non-residential buildings.

This will enable easy envelope performance calculations using "Styrofoam™" to be performed on a web browser from the initial design stage. This initiative has been realized through data linkage with insulation material information provided by Takashima Co., Ltd. (Chiyoda-ku, Tokyo, hereinafter "Takashima"), a trading company that handles a wide range of building materials and industrial materials.

■ About the Energy-saving Review Web Service

In recent years, energy conservation standards for buildings have been progressively strengthened, and from April 2026, energy conservation regulations for medium-sized non-residential buildings have also been reinforced. Against this background, the importance of considering specifications while checking the energy-saving performance of buildings from the design stage has increased.

The Energy-saving Review Web Service is a design support service that allows users to check the envelope performance (BPIm) and primary energy consumption (BEIm) of non-residential buildings on a web browser while integrating building material selection and energy-saving calculations.

By inputting building specifications at the design stage, it is possible to perform energy-saving compliance judgments and performance checks with ZEB standards in mind, and it also supports reviews using actual product data from building material manufacturers.

【Expected Effects in Design Practice】

1. Envelope Performance Review Based on Actual Product Data

   Since the product name, thickness, thermal conductivity, and other specifications of Styrofoam™ can be directly called from the selection screen, the hassle of tedious manual input is eliminated, and envelope performance calculations are simplified.
