Green Globes Multifamily for New Construction
Integrated & Collaborative Design for Sustainable Construction
Green Globes Multifamily for New Construction (Green Globes MF NC) provides a certification option that meets the needs of owners and project teams with multifamily projects. Green Globes MF NC includes:
- Minimum requirements for energy and water efficiency that ensure resource conservation and best practices for future occupancy in a new or renovated space.
- Flexibility and multiple pathways to success
- A question set that prompts users to think critically about their project
- Third-party Assessor Design Review to evaluate current design and projected rating, allowing opportunity for changes to be made prior to construction.
- Third-party Assessor On-site review providing assurance of certification claims
- GBI customer service and technical support for step-by-step guidance
These attributes make Green Globes the first choice for multifamily new construction. By engaging with Green Globes and reading through the question set in this manual, you will discover new ways to incorporate sustainable design into construction and adopt green building best practices in your multifamily project.
Minimum Requirements for Green Globes Multifamily for New Construction
To be certified through Green Globes Multifamily for New Construction, projects must achieve all Minimum Requirements for either Energy or Water. In addition, projects must also achieve a minimum 35% total score out of all applicable points in the Green Globes Multifamily program. Minimum Requirements must be met to be eligible for the program but are separate from the criteria used in the assessment. Points are awarded for criteria within the survey, not for meeting the minimum requirements.
Select either Energy or Water Minimum Requirements.
ENERGY MINIMUM REQUIREMENTS
Building design must achieve 15% or greater projected energy consumption savings over the respective established baseline and must meet all three (3) Energy Minimum Requirements.
1. Energy Efficient Design
Projects must achieve 15% or greater projected energy consumption savings through one of the following options.
Generate an energy model for the entire building, input energy use and building characteristics into ENERGY STAR Target Finder, and choose one of the following:
Option 1: ENERGY STAR® Score - For multifamily properties with 20 or more units. Achieve an ENERGY STAR performance score of 70 or greater in the Target Finder program. See 188.8.131.52.1 for additional guidance.
Option 2: EUI Reduction - Demonstrate the proposed design targets a 15% or greater reduction of energy use intensity (EUI) compared to the national median source EUI.
2. Energy Efficient Equipment & Products
Where not already covered by Energy Efficient Design, install ENERGY STAR-labeled, FEMP-designated, and/or AHAM Verifide energy efficient products and appliances (including clothes washers, dishwashers, and refrigerators), if such products and/or appliances are being provided.

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.
WATER MINIMUM REQUIREMENTS
Building must achieve 15% or greater projected water consumption savings over the respective established baseline and must meet both Water Minimum Requirements.
1. Water Consumption Savings
Choose either the Prescriptive Path or the Performance Path:
1.A Prescriptive Path - Low Flow Fixtures and Fittings
Projects following the Prescriptive Path for Water Consumption Savings must install WaterSense-labeled low flow fixtures and fittings where installed and/or supplied. In lieu of the WaterSense label, install low flow fixtures and fittings that meet or exceed prescribed, more stringent volume ratings:
- Private lavatory faucets – 0.8 gpm
- Public lavatory faucets – 0.5 gpm
- Kitchen faucets – 1.5 gpm
- Showerheads – 1.75 gpm
1.B Performance Path - EPA 1-100 Water Score
Projects following the Performance Path for Water Consumption Savings must achieve 15% or greater projected water consumption savings by achieving a water score of 70 or greater using EPA’s 1-100 Water Score for Multifamily Buildings within Portfolio Manager.

2. Water Performance Monitoring & Tracking
Confirm that the local utility or on-site master water meter(s) provide, at a minimum, aggregated whole-project water consumption data. Where local utility or current meters do not provide such data install water meters that do.
Commit to entering water 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.
GBI reserves the right to issue energy or water exceptions on a case-by-case basis as needed for unique circumstances, e.g., function of the building requires a limited amount of high flow fixtures.
Multifamily projects must still meet the 15% or greater energy or water consumption savings requirement.
