Introduction

In the pursuit of enhanced building energy performance, One Building has officially launched a new free web service aimed at non-residential buildings. This innovative tool incorporates detailed product information of the DuPont Styrofoam™ series, a well-known extruded polystyrene foam insulation, enabling architects and builders to proficiently evaluate the energy efficiency of building envelopes during the design phase. By leveraging real product data, this service becomes an indispensable resource for anyone looking to ensure compliance with the increasingly stringent energy code regulations coming into effect.

Overview of the Energy Efficiency Web Service

The Energy Efficiency Web Service introduced by One Building emerges against the backdrop of progressively stringent energy-saving standards in the construction sector. Starting from April 2026, the regulations targeting medium-sized non-residential buildings will become more rigorous. It is crucial, therefore, for architects and developers to meticulously review the energy performance specifications of their designs from the outset.

This web service enables simultaneous selection of building materials and energy-saving calculations, allowing users to examine exterior insulating performance (BPIm) and primary energy consumption (BEIm) directly within their browser. By inputting building specifications during the design stage, users can assess energy compliance and performance while utilizing verified product data from manufacturers.

Enhancements through Styrofoam™ Integration

Expected Benefits in Design Practice

1. Streamlined Performance Assessments: The web service allows users to quickly call up details such as the Styrofoam™ product name, thickness, and thermal conductivity directly from the selection interface. This feature eliminates the cumbersome need for manual input, making it easier to conduct exterior performance calculations quickly.

2. Efficient Comparison of Insulation Options: Users have the capability to compare various insulation specifications and their performance, facilitating a smoother discussion about insulation choices that best fit specific property requirements.

3. Rational Insulation Planning in Design Phase: By reviewing the results of insulation performance calculations, architects can make informed decisions on insulation specifications, ensuring a logical approach to building envelope thermal planning.

4. Enhanced Proposal Credibility: Providing calculations grounded in the specifications of actual products can clarify design rationale and improve the reliability of energy performance proposals when presented to clients.

About Styrofoam™

Manufactured by DuPont Styro Corporation, Styrofoam™ is a renowned extruded polystyrene foam insulation product, combining high insulating performance with durability. Its compliance with JIS A 9521 for building insulation materials offers thermal conductivity ratings ranging from 0.036 to 0.022 W/(m·K), ensuring consistent insulation effectiveness. The closed-cell structure of Styrofoam™ prevents moisture absorption, thereby maintaining stable thermal performance over an extended period and making it versatile across various architectural applications, including residential and non-residential buildings.

About DuPont Styro Corporation
