From BEI calculation and energy code compliance to BELS, CASBEE Architecture, CASBEE Wellness Office, WLC, and BEST/EnergyPlus simulation โ our experts provide comprehensive support for building environmental performance.
Comprehensive support from energy code compliance to CASBEE, WLC, and dynamic simulation
We use the Standard Input Method to maximize your building's energy performance rating. This method yields more favorable BEI scores than the Model Building Method.
Handled directly by certified energy compliance reviewers. We provide full support for applications to registered energy assessment bodies nationwide.
We support BELS (Building Energy-efficiency Labeling System) applications, aiming for the highest possible rating.
BELS rates buildings from 1 to 5 stars based on energy performance. The Standard Input Method helps achieve higher ratings.
We support CASBEE Architecture assessments for new construction, existing buildings, and renovations, proposing optimal strategies for achieving S-rank.
Assessment focused on occupant health and comfort. Ideal for ESG investment and well-being management initiatives.
We perform dynamic HVAC load calculations using BEST (Building Energy Simulation Tool), widely used in Japan. Detailed hourly thermal load simulation supports optimal HVAC system design.
High-precision analysis using EnergyPlus, the global standard simulation engine. Supports international building performance standards and green building certifications.
We calculate total COโ emissions across the entire building lifecycle (embodied + operational carbon), supporting environmental impact transparency for a decarbonized society.
Global attention is shifting beyond operational energy (BEI) to include embodied carbon in building materials. With WLC disclosure mandates on the horizon, early assessment directly supports ESG compliance and corporate value.
Expertise, speed, and security โ the three pillars of our reliable service
Reference pricing for BEI energy calculation services. All prices are before tax.
We handle document preparation and review response for energy compliance and BELS applications.
Reference pricing for BEI calculation + application support (document prep and review included). BELS assessor fees not included.
Documents you need to prepare. We handle BELS and energy compliance application documents, so please provide the drawings and equipment schedules listed below.
Smooth support from inquiry to delivery
The Standard Input Method provides a more accurate and favorable energy performance rating, recommended for BELS certification and subsidy applications. The Model Building Method is suitable when cost savings are a priority. We'll recommend the best approach for your project.
Yes. We accept partial requests such as BEI calculation only, compliance application only, or BELS application only.
Dynamic simulation is valuable for HVAC load prediction and equipment optimization during design, especially for ZEB targets. EnergyPlus also supports LEED and other international certifications. Combined with BEI calculation, it ensures more reliable energy-efficient design.
WLC quantifies total COโ emissions across a building's entire lifecycle โ from material manufacturing and transport through operation to demolition. It's an increasingly essential metric for ESG disclosure and decarbonization strategy.
Yes. Systematic planning from the design stage makes high-rank certification achievable. We propose optimal assessment strategies tailored to your building's characteristics.
We are ISO 27001 certified and handle all confidential data under strict security protocols. Your information is safe with us.
For approximately 2,000ใก, expect 1-2 weeks from drawing receipt. For around 5,000ใก, approximately 3 weeks. Timelines may vary with building use and complexity. Please contact us if you have schedule constraints.
