EcoBroker is earned by completing three online modules (Environmental, Energy, Green Market Advantage), each with a passing assessment at 70%, plus annual EcoBroker International membership. The curriculum aligns to RESNET (HERS Index, 100 = reference, 0 = net-zero), ENERGY STAR programs (Single-Family New Homes), DOE ZERH, USGBC LEED for Homes, NGBS (ICC 700), and the Appraisal Institute's Residential Green and Energy Efficient Addendum.

Sample EcoBroker Practice Questions

Try these sample questions to test your EcoBroker exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1On the HERS Index used by RESNET-certified raters, a NEW home with a HERS score of 70 means it is approximately:

A.70% less efficient than the reference home

B.30% more energy-efficient than a standard new home built to a baseline code reference

C.Equal in efficiency to the reference home

D.A net-zero home

Explanation: The HERS (Home Energy Rating System) Index uses 100 as the reference and 0 as net-zero. Each point below 100 is roughly 1% more efficient than the reference. A HERS 70 home is about 30% more efficient than the reference.

2The ENERGY STAR program is administered by:

A.NAR

B.U.S. EPA and U.S. DOE jointly

C.HUD

D.RESNET

Explanation: ENERGY STAR is a joint program of the U.S. Environmental Protection Agency (EPA) and U.S. Department of Energy (DOE), administered primarily through the EPA. It certifies energy-efficient products, homes, and buildings.

3LEED for Homes is administered by the:

A.EPA

B.U.S. Green Building Council (USGBC)

C.HUD

D.DOE

Explanation: LEED (Leadership in Energy and Environmental Design) is developed and administered by the U.S. Green Building Council (USGBC), with project certification through Green Business Certification Inc. (GBCI).

4Which of the following is the BEST description of indoor air quality (IAQ) improvement in a home?

A.Install bigger TVs

B.Source-control of pollutants, mechanical ventilation per ASHRAE 62.2, high-efficiency MERV filtration, radon mitigation where indicated, and low-VOC materials

C.Use more candles

D.Open windows only on cold days

Explanation: IAQ improvement follows three layers: source control (eliminate pollutants), ventilation (e.g., ASHRAE 62.2 whole-house rates), and filtration. Radon mitigation, low-VOC materials, and proper combustion appliance venting are also core practices.

5A solar photovoltaic (PV) system on a residence converts sunlight into:

A.Heat for water

B.Direct-current electricity, then inverted to alternating-current for use in the home and grid

C.Natural gas

D.Geothermal energy

Explanation: PV cells convert sunlight to DC electricity, which an inverter converts to AC for household use and grid export. Solar thermal (separate technology) is what heats water.

6A solar PV system is interconnected to the grid under a net-metering arrangement. Net metering generally:

A.Charges the homeowner extra

B.Credits the homeowner for excess electricity exported to the grid, often at the retail rate or a defined credit rate per state utility rules

C.Disconnects the home from the grid

D.Stores energy in batteries automatically

Explanation: Net metering credits the customer's bill for excess generation exported to the grid. Specific credit rates and reconciliation methods vary by state utility commission. Batteries are separate equipment.

7The federal Residential Clean Energy Credit (formerly Section 25D, often cited as the 'solar tax credit') provides:

A.No credit

B.A federal income-tax credit for a percentage of the cost of qualified solar PV, solar water heating, small wind, geothermal heat pump, and battery storage installed at a residence

C.A grant from HUD

D.An MLS fee waiver

Explanation: The Residential Clean Energy Credit (IRC 25D) provides a federal income-tax credit for qualified residential clean-energy equipment. The credit rate and eligible technologies are set by the Inflation Reduction Act through specified years.

8A home's blower-door test measures:

A.Roof strength

B.Air leakage of the building envelope, typically reported in ACH50 (air changes per hour at 50 pascals) or CFM50

C.Solar output

D.Water hardness

Explanation: A blower-door depressurizes (or pressurizes) the house to 50 pascals and measures airflow needed to maintain the pressure differential. Lower ACH50 indicates a tighter envelope.

9A duct blaster test measures:

A.Plumbing leaks

B.Air leakage in the duct system, expressed in CFM at 25 pascals (CFM25) or total leakage vs leakage to outside

C.Roof leaks

D.Solar inverter efficiency

Explanation: Duct leakage testing measures total air leakage and/or leakage to outside conditioned space. Excessive duct leakage degrades HVAC efficiency and IAQ. ENERGY STAR and IECC have leakage thresholds.

10A heat pump (air-source or ground-source) is more efficient than a resistance electric heater because it:

A.Generates heat from nothing

B.Moves heat from one place to another, providing several units of heating output per unit of electricity (high COP/HSPF)

C.Burns natural gas

D.Uses solar panels by default

Explanation: Heat pumps move heat (vapor-compression cycle) rather than create it, achieving COPs typically 2-5 (i.e., 200-500% efficient on heat output vs electricity input). Resistance heat is one-to-one.

About the EcoBroker Exam

EcoBroker Certified is the longest-running green real estate designation, administered by EcoBroker International.

Frequently Asked Questions

What is the EcoBroker Certified designation?

EcoBroker Certified is a long-running green real estate designation from EcoBroker International. The 18-hour curriculum has three modules: Environmental Advantage, Energy Advantage, and Green Market Advantage. Designees learn to identify, market, value, and negotiate green features in residential real estate transactions.

How is EcoBroker different from NAR's GREEN designation?

EcoBroker is administered by EcoBroker International (a separate company), while GREEN is administered by NAR. Both cover green building, energy efficiency, and green marketing. EcoBroker has been around longer and is structured as three modules (Environmental, Energy, Green Market Advantage); NAR's GREEN is a separate, NAR-administered designation. Many agents take only one.

How much does EcoBroker cost?

Course tuition typically runs $300-$500, plus annual EcoBroker International membership to maintain the designation. Pricing changes; check EcoBroker.com for current rates. Some local associations offer member discounts.

What technical topics does the exam cover?

The exam covers HERS Index interpretation (100 = reference, 0 = net-zero), ENERGY STAR program structure (EPA/DOE joint program), LEED for Homes (USGBC/GBCI), DOE Zero Energy Ready Home (ZERH), NGBS (ICC 700), solar PV (DC vs AC, net metering, IRC 25D), HVAC (SEER2, AFUE, heat pumps), envelope (low-E, insulation R-values, ASHRAE 62.2 ventilation), and EEMs/PACE financing.

How long does it take to earn EcoBroker?

Most candidates complete the three modules in 4-8 weeks of part-time study, totaling about 18 instructional hours of content plus 25-45 hours of study and assessment time. Self-paced online format allows faster completion if you can dedicate consistent study time.

Is EcoBroker worth it for residential agents?

EcoBroker is most valuable for agents working in markets where green features command price premiums or buyer interest (high-utility-cost regions, eco-conscious metros, new construction with LEED/ENERGY STAR certification). The credential teaches accurate marketing (avoiding greenwashing under FTC Green Guides) and how to support appraisers using the Appraisal Institute green addendum.

What is the HERS Index?

The Home Energy Rating System (HERS) Index is RESNET's standardized scale where 100 = reference home (built to a baseline code), each point below 100 is about 1% more efficient, and 0 = net-zero. A HERS 50 home uses about 50% less energy than the reference. HERS is the most common new-home energy rating; many MLS green fields capture it.
