Our energy efficiency calculator provides preliminary estimates to help you quickly understand the potential benefits of sustainable construction and energy efficiency design choices for your building project. All figures are approximate and based on average global data, standardized assumptions, ASHRAE climate zones (which classify locations by temperature, humidity, and heating/cooling needs for accurate energy modeling), and typical building performance benchmarks.
Here's what each key metric means:
Annual Energy Consumption (baseline): This shows the estimated total energy use (in kWh or similar units) per year for a standard, non-energy-efficient building of similar size, type, and location in the selected climate zone. It represents a "business-as-usual" scenario using conventional construction practices, materials, and systems — serving as the reference point for comparison.
Estimated Annual Savings: The projected reduction in energy consumption (and corresponding cost savings in currency of your choice) each year after implementing your chosen energy-efficiency measures (better insulation, high-efficiency HVAC/MEP systems, solar panels, shading devices, efficient lighting). Savings are calculated as the difference between the baseline and your improved design.
Savings percentage: The relative improvement over the baseline: for example, "30%" means your building would use approximately 30% less energy annually compared to a standard building under the same conditions. Higher percentages indicate stronger performance and greater long-term value, and great chances of getting energy-efficiency or green building certification.
Payback Period: The estimated number of years required to recover the additional upfront investment cost of the energy-saving measures through accumulated annual energy bill savings (simple payback calculation). A shorter payback (4–6 years) is generally considered attractive for most commercial projects, depending on financing, energy prices, and incentives. Note: This does not account for time value of money, inflation, or potential increases in energy costs; real-world results can be even more favorable.
Property Value Increase: A rough estimate of the potential uplift in your building's market value due to energy efficiency and green features. Studies and market data show that certified or high-efficiency commercial buildings often command premiums: typically 5–15% higher sale/rental prices, faster leasing, lower vacancy rates, and increased NOI (net operating income). Green-certified properties can see even stronger effects in competitive markets.
Important Notes
These are preliminary, indicative estimates derived from generalized data and modeling assumptions; they are not a substitute for detailed site-specific engineering analysis. Actual results depend on precise project details, design solutions, local energy tariffs, incentives, construction management, construction conditions, and operational behavior.

We can provide in-depth simulations aligned with your exact location, building codes, and goals.
