Achieve Comfort and Sustainability with ZEB
Moving beyond energy austerity to create spaces where people thrive — comfortable, healthy, and productive.
We deliver buildings that prioritize occupant health and well-being.
Human Centric ZEB
From enduring energy savings to people-first comfort and health.
The ZEB Inc. Philosophy
We go beyond conventional ZEB certification to put people first
Focused solely on energy balance
- Achieving energy reduction targets is the primary goal
- BEI compliance takes top priority
- Occupant comfort often sacrificed
- Health and productivity not evaluated
Balancing comfort and environment in people-first buildings
- Energy targets achieved as a matter of course
- Full BEI compliance guaranteed
- Occupant health and productivity come first
- Sustainable energy savings without sacrifice
Forced austerity hurts the bottom line
Uncomfortable environments cause health issues and reduced focus. Comfortable spaces boost employee retention, productivity, and directly impact profitability.
Healthy children benefit everyone
Proper ventilation and humidity control prevent infections and reduce absences. Parents take fewer sick days, and healthcare costs decrease — reducing societal costs overall.
Three Key Benefits of ZEB
Comfort & Health
Enhanced Intellectual Productivity
Optimal thermal and lighting environments boost focus and creativity.

Community Resilience Hub
On-site energy generation and storage support business continuity during disasters.
Economic Value
Minimized Life-Cycle Cost
Reduced utility bills dramatically compress the building’s total cost of ownership.
Premium Building Status
High BELS ratings enhance tenant appeal and asset value.

Path to ZEB Realization
Click each step to see the details
1 Basic Planning
Decide to pursue ZEB and plan with an estimated 10% cost premium. We provide early-stage advisory on design considerations critical for ZEB achievement.
2 Design
Incorporate ZEB requirements into bid specifications. We calculate primary energy consumption (Standard Input Method) from the schematic design and propose equipment to achieve ZEB targets, verifying compliance through any design changes.
3 Construction
Verify selected equipment meets ZEB performance requirements. Recalculate BEI with every design change during construction to ensure ZEB standards are reliably maintained.
4 Completion
Obtain ZEB certification (BELS) upon completion. We handle energy code compliance submissions and BELS applications based on the final design documentation.
5 Operations
Leverage BEI input sheets and BEMS for ongoing energy monitoring, analysis, and operational optimization to sustain energy savings and CO₂ reductions over the building’s lifetime.

Achieved
1 ZEB Feasibility Study
Thoroughly investigate the building’s current energy performance and equipment conditions. Visualize potential and challenges, including CO₂ reductions, energy cost savings, estimated retrofit costs, and economic viability — the most critical first step toward ZEB realization.
2 Challenge Analysis
Identify specific barriers including cost-effectiveness, construction constraints, and phasing requirements. Assess occupied-building retrofit feasibility, phased renovation approaches, and available subsidy programs.
3 Plan Development
Create the optimal, achievable renovation plan based on our expertise. Economic analysis comparing ZEB retrofit vs. standard renovation provides key evidence for stakeholder decision-making.
4 Retrofit Execution
Execute construction with realistic planning for occupied buildings. Prepare bid documents ensuring designed energy performance, and verify ZEB compliance is maintained through any construction changes.
5 Comfort Achieved
Verify ZEB performance is maintained in as-built documentation. Through testing and adjustment, guarantee the balance of comfort and energy savings. BEMS-based monitoring drives continuous improvement.
For existing buildings, start with a ZEB Feasibility Study
By quantifying barriers and visualizing the path forward with data, we dramatically increase the likelihood of successful ZEB realization — delivering actionable plans, not paper exercises.
Selected Clients
Frequently Asked Questions
Can I consult even if we haven’t decided to pursue ZEB yet?
Absolutely. A feasibility study is the first step in determining whether ZEB is viable and the most realistic path forward. Simply share the building use, floor area, and location — initial consultations are free of charge.
Do you support both new construction and existing building retrofits?
Yes. For new construction, we provide advisory from the schematic design stage through BEI calculation and design support. For existing buildings, we cover the full scope from feasibility studies through design, construction-stage performance management, and operations.
How much additional cost does ZEB require?
For new construction, approximately 10% above standard costs is a typical benchmark. For existing buildings, costs vary by condition, but insulation and energy recovery ventilation enable HVAC downsizing — and life-cycle costs (LCC) are often lower than standard renovation.
Are government subsidies available?
Yes. Multiple subsidy programs from the Ministry of the Environment, Ministry of Economy, Trade and Industry, and Ministry of Education are available. We provide comprehensive support from feasibility study through application, post-award administration, inspections, and final reporting.
Can you handle only BEI calculation or design support?
Yes. We accept partial engagements — BEI calculation only, energy code compliance only, BELS application only, and more. We also provide design advisory for architects unfamiliar with ZEB and BEI recalculation for design changes.
Can retrofits be done while the building remains occupied?
Yes. Occupied-building retrofit feasibility, required closure scope, phased renovation approaches, and construction schedules utilizing school breaks or other low-occupancy periods are all assessed within our feasibility study.
What information do I need for an initial consultation?
Building use, total floor area, location, year of construction (for existing buildings), and current major equipment status are most helpful. Even if drawings and energy data are not yet available, please feel free to reach out.
