Certification return calculator

Calculate what your project gains from certification

If you will operate it, how much more the asset is worth. If you will sell it, how much each buyer saves. For EDGE, LEED, WELL or Fitwel.

What each certification measures

  • EDGEEnergy, water and materials efficiency. Requires at least 20% savings in each one to certify.
  • LEEDWhole-building performance: energy, water, materials, indoor quality and operations.
  • WELLOccupant health and well-being. Its return is measured in rent, not in energy savings.
  • FitwelOccupant health, with a faster process. Its return is measured in rent, not in energy savings.

Methodology

Where do the numbers come from?

Each result combines a public figure for each certification with reference values for your country and project type. We highlight the formulas your current selection uses.

What you see in your result

If you will operate or lease

Added building value

The market values an income property by dividing its annual net operating income by the cap rate. If certification raises net income, value goes up.

added net operating income÷cap rate

Calculate your project to see it applied.

If you will sell

Savings per unit

The whole building’s savings split across its units and brought down to a month, which is how a buyer compares it with their expenses.

annual savings÷units÷12

Calculate your project to see it applied.

What feeds the calculation

EDGE and LEED

Energy and water savings

The certification’s savings % applied to a conventional building’s consumption, at your country’s rates.

m²×baseline use×rate×savings %
WELL and Fitwel

Added rent

Health certifications: their return is rent, 4.4% to 7.7% more per m². We do not estimate energy savings.

m²×monthly rent×12×4.4–7.7%
All

Cost to certify

The certifying body’s fee plus the construction cost premium: 0–3% for EDGE and 1–5% for LEED depending on project type.

fee+m² × cost × % premium

Sources and assumptions

Three public figures back every result

We do not promise what we cannot back up. Every percentage comes from a study or a certifying body, which is why everything is shown as a range.

EDGE

≥20%

minimum savings in energy, water and embodied energy in materials. It is required to certify, so the result is conservative.

WELL · Fitwel

+4.4–7.7%

higher rent per m² in buildings with a health certification. That is why their return is measured in rent, not energy.

Certification fees

EDGE: USD 349 + USD 0.22 per m². LEED: USD 1,200 to 22,500 depending on floor area. Consumption, local energy and water rates, maintenance, cap rate and timelines are reference values by country and project type.

What is not included

Consulting fees, energy modeling, commissioning, tax incentives or green financing. The projection uses today’s rates with no inflation, so it tends to underestimate the return.

If your tenants pay the utilities

The tenant receives the energy and water savings. For you, they show up in the rent you can charge, not in your direct net operating income.

How much does the value of a building increase with EDGE, LEED, WELL, or Fitwel certification?

It depends on how much your net income increases. A LEED building spends on average 25% less on energy, 11% less on water, and 19% less on maintenance (PNNL, 2011), and one with WELL or Fitwel records between 4.4% and 7.7% more rent per m² (MIT, 2020). That additional net income divided by the market cap rate provides an estimate of the asset's increased value.

How much can be saved in energy and water with EDGE or LEED?

An EDGE building saves at least 20% in energy, water, and embodied energy in materials, as this is a certification requirement. LEED buildings consume on average 25% less energy and 11% less water than a conventional building, according to a PNNL study of 22 buildings in the U.S. (2011).

If I am planning to sell the project, is it really worth it to certify it?

Operational savings are realized by the buyer, not the seller. For the developer, the value lies in the sales pitch: how much less each buyer pays in utilities every month. The calculator estimates this per unit so you can compare it against the additional cost of certification.

Can WELL and Fitwel certifications also help reduce a project's energy consumption?

That is not their primary goal. WELL and Fitwel certify the health and well-being of occupants. Their return is reflected in rent: between 4.4% and 7.7% more per m², according to the MIT Real Estate Innovation Lab (2020).

How accurate is the Leaf certification return calculator?

This is an estimate. It uses averages from published studies and reference values by building type and country, which is why it provides ranges rather than a single number. For an analysis of your specific project, the Leaf team works with your blueprints, specifications, and market data.
