Green Globes® Multifamily for New Construction Protocol
Green Globes® Multifamily for New Construction (NC) provides a certification option that meets the needs of owners and project teams with multifamily projects pursuing financial incentive.
Green Globes Multifamily for NC includes:
- Minimum requirements for energy 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 Onsite assessment 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 New Construction Certification Process
Minimum Requirements for Green Globes Multifamily for New Construction
To certify with Green Globes Multifamily for New Construction (NC), projects must achieve all minimum requirements for Ventilation and Energy. In addition, projects must also achieve a minimum of 35% of 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 in the assessment. Points are awarded for criteria within the Green Globes questionnaire, not for meeting the minimum requirements.
Meet all Ventilation Minimum Requirements, and the Energy Minimum Requirements.
VENTILATION MINIMUM REQUIREMENTS
Building design must establish and meet minimum indoor air quality performance by meeting all three Ventilation Minimum Requirements listed below.
1. Ventilation Air Quantity
The quantity of ventilation for the building is compliant with one of the following:
- Option 1: ANSI/ASHRAE Standard 62.1-2013 Ventilation for Acceptable Indoor Air Quality;
- ANSI/ASHRAE 62. 1-2013 (read only): https://ashrae.iwrapper.com/ViewOnline/Standard_62.1-2013
- Option 2 (Lowrise and Midrise Multifamily Only): ANSI/ASHRAE Standard 62.2-2013 Ventilation for Acceptable Indoor Air Quality in Low-Rise Residential Buildings.
- ANSI/ASHRAE 62.2-2013 (read only): https://ashrae.iwrapper.com/ViewOnline/Standard_62.2-2013
- Option 3: ICC International Mechanical Code (ICC IMC 2015), Chapter 4;
- ICC International Mechanical Code 2015, Chapter 4: https://codes.iccsafe.org/content/IMC2015/chapter-4-ventilation
- Option 4: IAPMO UMC (2015) Uniform Mechanical Code;
- 2015 Uniform Mechanical Code: http://epubs.iapmo.org/UMC/mobile/index.html#p=1
- Option 5: Local codes or standards (if more stringent).
2. Air Handling Equipment
Equip air handling equipment with filtration as follows:
- Air handling equipment that provide ventilation air (e.g. central mixed air equipment, make-up air equipment, ventilation equipment for “compartmental” systems such as fan coils or unitary heat pumps): minimum MERV 13; and
- Terminal equipment that circulates room or zone air (e.g. fan coils, unitary heat pumps): minimum MERV 8.
Not applicable where non-ducted circulating unitary equipment serves only a single zone (e.g. unit heaters, force-flows).
3. Operations & Maintenance Plan
Specify regular ventilation maintenance and indoor air quality (IAQ) in an Operations & Maintenance (O&M) Plan. Ensure that specific issues (e.g. dirty air filters, dirty air return grills, maintenance of mechanical units, etc.) are identified and a regular maintenance plan is developed for maintaining IAQ goals.
ENERGY MINIMUM REQUIREMENTS
Building design must achieve greater than 15% 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 greater than 15% 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 greater than 15% 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.
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 15% or greater energy consumption savings requirement.
