'Heat Insulation x CO2 Reduction' Service Launches: Quantifying Factory Heat Relief and Energy Savings via 3D Airflow Simulation Before Construction

Overview

SUNUP Co., Ltd. (Headquarters: Gamagori City, Aichi Prefecture; CEO: Katsutoshi Oba), an exclusive installer of 'Thermo Barrier' heat insulation sheets, has partnered with FaciLabo (Location: Okazaki City, Aichi Prefecture; Representative: Ryoji Inaguma), an air-conditioning airflow simulation specialist, to launch a one-stop 'Heat Insulation x Airflow Simulation' service for CO2 reduction.

In conventional heat insulation projects, effects were only known after construction, making it difficult for companies to decide whether the investment would be worthwhile or if insulating just the roof would suffice. This service compares multiple construction patterns through pre-simulation and presents the most cost-effective plan with hard numbers.

Mandatory CO2 Emission Trading System in FY2026

Starting in FY2026, the second phase of the Emission Trading System (GX-ETS) will become mandatory for approximately 300 to 400 companies emitting over 100,000 tons of CO2 annually. While large enterprises are the primary targets, there is a growing trend where SMEs in the supply chain are requested by their major clients to report energy-saving status and CO2 reduction efforts.

However, for many SMEs, identifying specific CO2 reduction methods and evaluating ROI is not easy. Feedback from the field often indicates a need to know 'what to spend on and what effect to expect.'

How It Differs from Conventional Insulation Projects

### 1. 3D Visualization of Temperature and Airflow Before Construction This service creates a 3D model based on factory blueprints and uses airflow analysis software to simulate temperature distribution and air movement. This visualizes 'which areas are particularly hot' and 'where hot air is stagnating.'

### 2. Comparison of Multiple Construction Patterns for Optimal Planning The cost and effect of insulation vary greatly depending on the scope (e.g., roof only vs. roof + windows vs. roof + windows + walls). This service conducts simulations for each scope and presents the temperature reduction effects in a comparison table.

For example, in one factory, patterns were compared: - Baseline: 39.1°C - Roof only: 37.2°C (-1.9°C) - Roof + Windows: 37.1°C (-2.0°C) - Roof + Windows + Walls: 36.7°C (-2.4°C) This data allows for numerical decision-making to avoid unnecessary over-investment.

### 3. Integrated Estimation from Temperature Drop to CO2 Emissions Lowering factory temperatures reduces air conditioning load, leading to electricity savings. As a general guide, raising the AC setting by 1°C can reduce power consumption by about 10%. Projects that lower room temperature by up to 11°C offer significant savings.

This service converts electricity savings into CO2 emissions using emission factors published by the Ministry of the Environment, providing an estimate of annual CO2 reduction. This can be used as reporting material for GX-ETS or supply chain requests.

Simulation Results: Temperature Drops Confirmed in 3 Factories Analysis of three factories with different sizes and structures confirmed temperature drops at working height (z=1.5m): - Factory A: 44.0°C -> 37.4°C (-6.6°C) - Factory B: 42.0°C -> 36.7°C (-5.3°C) - Factory C: 39.1°C -> 37.2°C (-1.9°C) (Ambient temp 35°C, no AC considered during analysis).
