Takashima & Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo, Representative Director: Koichi Takashima, hereinafter "the Company") has started providing product information for "Styrofoam™", an extruded polystyrene foam insulation material manufactured by DuPont Styro Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo, Representative Director: Tamotsu Aritomo, hereinafter "DuPont Styro"), for which the Company acts as a sales agent, on the "Energy Saving Study WEB Service (hereinafter 'Energy Saving Study WEB')" for non-residential buildings provided by one building Co., Ltd. (Headquarters: Meguro-ku, Tokyo).
Through this initiative, envelope performance calculations using "Styrofoam™" can be easily performed on a web browser from the initial design stage.
■ About "Energy Saving Study WEB"
In recent years, energy conservation standards for buildings have been gradually strengthened, and from April 2026, the mandatory energy-saving standards for medium-scale non-residential buildings will be raised. Against this background, it is becoming increasingly important to consider specifications while checking the energy-saving performance of buildings from the design stage.
The "Energy Saving Study WEB" 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 calculation.
By entering the building specifications at the design stage, users can perform performance checks looking ahead to energy conservation compliance judgments and ZEB standard levels, and the service also supports studies using actual product data from building material manufacturers.
■ Design Studies Made Possible by Styrofoam™ × "Energy Saving Study WEB"
[Expected Effects in Practical Design Work]
1. Envelope performance studies based on actual product data: Specifications such as the product name, thickness, and thermal conductivity of Styrofoam™ can be called up directly from the selection screen, eliminating the hassle of complicated manual input and enabling efficient envelope performance calculations.
2. Streamlined comparative study of insulation specifications: Envelope performance can be checked while comparing multiple insulation specifications, allowing smooth consideration of insulation specifications according to property conditions.
3. Rational insulation planning at the design stage: Insulation specifications can be studied while checking the calculation results of envelope performance, making it possible to proceed with a rational envelope plan based on insulation performance at the design stage.
4. Improved persuasiveness of proposals using actual product data: Calculation results based on actual product specifications can be presented, leading to clarified design rationale and improved reliability of proposals when explaining energy-saving performance to clients.
■ About Styrofoam™
Styrofoam™ is an extruded polystyrene foam insulation material (XPS) provided by DuPont Styro Co., Ltd., and is widely adopted as a building insulation material that combines high insulation performance and durability.
It complies with JIS A 9521 "Thermal insulation materials for buildings" and has insulation performance with a thermal conductivity of 0.036 or less to 0.022 or less (W/(m・K)) depending on the product grade.
Due to the uniform closed-cell structure unique to extruded polystyrene foam, it has low water absorption and can maintain stable insulation performance over a long period, making it widely used in various architectural applications regardless of whether residential or non-residential.
■ About DuPont Styro Co., Ltd.
DuPont Styro Co., Ltd. is an insulation manufacturer that manufactures and sells the extruded polystyrene foam insulation material "Styrofoam™" in Japan, backed by the technology of DuPont, a global chemical manufacturer. Over the years, the company has developed technology and supplied products for extruded polystyrene foam insulation, contributing to the improvement of insulation performance in Japanese residential and non-residential buildings. Styrofoam™ is widely adopted in the construction field for its stable performance and quality, even as high insulation performance is required as a product subject to the Top Runner Program for building materials. Today, it is used in various building applications such as housing, public facilities, and commercial facilities as an insulation material that contributes to improving energy-saving performance and extending the life of buildings.
