Green Globes Multifamily for New Construction 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://www.ashrae.org/technical-resources/standards-and-guidelines/read-only-versions-of-ashrae-standards
• 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://www.ashrae.org/technical-resources/standards-and-guidelines/read-only-versions-of-ashrae-standards
• 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 to terminal devices (e.g. central air handler, DOAS, etc.):minimum MERV 13; and
• Single zone terminal devices (e.g. fan-coil): minimum MERV 8.

Not applicable where non-ducted circulating unitary equipment serves only a single zone (e.g. unit heaters, force-flows, mini-split heat pumps).

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 respective established baseline and must meet all three (3) Energy Minimum Requirements.

1.Energy Efficient Design

Generate an energy model for the entire building, input energy use and building characteristics into ENERGY STAR Target Finder, and complete one of the following based on ENERGY STAR eligibility:

• Option 1: ENERGY STAR® Score – For multifamily properties with 20 or more units. Achieve an ENERGY STAR performance score of 80 or greater in the Target Finder program.
• Option 2: EUI Reduction – If not eligible for an ENERGY STAR Score. 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 and/or FEMP-designated 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 onsite 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.

Required Documentation – upload to Green Globes “v3” Software:

• Completed Minimum Requirement Survey
• Construction documents w/ ventilation code information
• ENERGY STAR Portfolio Manager Statement of Energy Design Intent (SEDI), or screenshot of ENERGY STAR Score
• Energy model outputs

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 Quality
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
• 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
• Option 3: ICC International Mechanical Code (ICC IMC 2015), Chapter 4; ICC International Mechanical Code 2015, Chapter 4
• Option 4: IAPMO UMC (2015) Uniform Mechanical Code; 2015 Uniform Mechanical Code
• 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, mini-split heat pumps).

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 20% or greater projected energy consumption savings over respective established baseline and must meet all three (3) Energy Minimum Requirements.

WATER MINIMUM REQUIREMENTS

Buildings must achieve 15% or greater projected water consumption savings over respective established baseline and must meet both Water Minimum Requirements.

1. Water Consumption Savings

Projects must install WaterSense-labeled low flow fixtures and fittings where installed and/or supplied. In lieu of the WaterSense label, low flow fixtures and fittings that meet or exceed the following 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

2. Water Performance Monitoring & Tracking

Confirm that the local utility or onsite 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.
