Green Globes® Multifamily for Existing Buildings Protocol

Green Globes® Multifamily for Existing Buildings (EB) provides a certification option that meets the needs of owners and project teams with multifamily projects pursuing financial incentive. 

Green Globes Multifamily Existing Buildings includes:

  • Minimum requirements for energy efficiency that ensure resource conservation through operations and tenant best practices
  • Flexibility and multiple pathways to success
  • A question set that prompts users to think critically about their project
  • Third-party assessor onsite review providing assurance of certification claims
  • GBI customer service and technical support for step-by-step guidance

Green Globes is a collaborative certification system designed to evaluate individual buildings and/or buildings within a portfolio and provides personalized feedback and recommendations for performance improvement.

Green Globes Multifamily for Existing Buildings Certification Process

Green Globes Multifamily for Existing Buildings Minimum Requirements

Projects must achieve all Energy Minimum Requirements. In addition, projects must also achieve a minimum of 35% of the applicable points in the Green Globes Multifamily EB protocol. Minimum Requirements must be met to be eligible for the program but are separate from the criteria in the assessment. Points are awarded for criteria within the Green Globes questionnaire, not for meeting the minimum requirements. 

ENERGY MINIMUM REQUIREMENTS

Demonstrate greater than 15% energy consumption savings over respective established baseline and meet all three (3) Energy Minimum Requirements.

1. Energy Performance

Choose either the ENERGY STAR® Portfolio Manager Path or the Energy Consumption Savings Path.

1.A ENERGY STAR® Portfolio Manager Path

Projects following the ENERGY STAR® Portfolio Manager Path must choose one of the following two options:

  • Option 1: ENERGY STAR® Score For multifamily properties with 20 or more units. Achieve an ENERGY STAR energy performance score of 70 or greater using the Portfolio Manager program.

OR

  • Option 2: EUI Reduction - Demonstrate a greater than 15% reduction of energy use intensity (EUI) compared to the national median source EUI.

1.B Energy Consumption Savings Path

For multifamily properties with less than 20 units and no energy model, demonstrate greater than 15% energy consumption savings over respective established baseline. Compare whole building energy data from previous 12 months against 3 contiguous years of energy consumption use within the previous 9 years (normalized for climate and occupancy). All data must be input into ENERGY STAR Portfolio Manager.

2. Energy Efficient Equipment & Products

Confirm Operations & Maintenance (O&M) policy to install ENERGY STAR-labeled, FEMP-designated, and/or AHAM Verifide energy efficient products and appliances (including clothes washers, dishwashers, and refrigerators), when such products and/or appliances are being replaced. Put into place an O&M policy for energy efficient equipment and products if there is no policy.

3. Energy Performance Monitoring & Tracking

Confirm that the local utility or on-site master energy meter(s) provide, at a minimum, aggregated whole-project energy consumption data for each energy utility type. Where local utility or current meters do not provide such data, install energy meters that do.

Commit to entering energy consumption data into ENERGY STAR Portfolio Manager to track ongoing performance and sharing of that data with Green Building Initiative. Document for future performance verification.


Exception Policy - GBI reserves the right to issue ventilation and energy exceptions on a case-by-case basis as needed for unique circumstances. Multifamily projects must still meet the 25% or greater energy consumption savings requirement.
