Takashima Corporation Begins Providing Product Information for DuPont Styro's "STYROFOAM™" Insulation Material on one building's "Energy Saving Review Web Service"

Takashima Corporation (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Koichi Takashima; hereinafter "the Company") has begun providing product information for DuPont Styro Co., Ltd.'s (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Kan Aritomo; hereinafter "DuPont Styro") extruded polystyrene foam insulation material "STYROFOAM™," which the Company handles as a sales agent, on the "Energy Saving Review Web Service" (hereinafter "Energy Saving Review Web") for non-residential buildings, provided by one building Co., Ltd. (Headquarters: Meguro-ku, Tokyo).

Through this initiative, building envelope performance calculations using "STYROFOAM™" can be easily performed on a web browser from the initial design stage.

About "Energy Saving Review Web"

In recent years, energy-saving standards for buildings have been progressively strengthened, and from April 2026, the energy-saving standard for compliance obligations for medium-sized non-residential buildings will be raised. Against this backdrop, the importance of reviewing specifications while confirming the building's energy-saving performance during the design phase is increasing.

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

By inputting building specifications during the design phase, users can perform energy-saving compliance judgments and performance checks with ZEB (Zero Energy Building) standards in mind, and it also supports reviews using actual product data from building material manufacturers.

Design Review Made Possible with STYROFOAM™ × "Energy Saving Review Web"

### [Expected Effects in Design Practice]

- Building Envelope Performance Review based on Actual Product Data: Since specifications such as product name, thickness, and thermal conductivity of STYROFOAM™ can be directly called up from the selection screen, the troublesome manual input can be eliminated, and building envelope performance calculations can be performed efficiently.

- Streamlining Comparative Review of Insulation Specifications: By comparing multiple insulation material specifications, building envelope performance can be confirmed efficiently.
