Green Globes Multifamily for Existing Buildings Protocols

Green Globes Multifamily for EB Minimum Requirements

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

1. Energy Performance

Meet the ENERGY STAR® Portfolio Manager Path (1.A), or the Energy Consumption Savings Path (1.B) if not ENERGY STAR eligible, and document the energy savings.

1.A ENERGY STAR® Portfolio Manager Path

Input energy use and building characteristics into ENERGY STAR Portfolio Manager and complete Option 1 if eligible for an ENERGY STAR Score.

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

*Note on Whole Building Energy Consumption Data – An energy model may be developed if you don’t currently have 12 months of energy data to use as your baseline, including scenarios where it is not possible to access all tenant utility data. The energy model must include the following systems:

1. All mechanical systems;
2. Domestic hot water systems;
3. Lighting;
4. Renewable sources of energy, as applicable;
5. Pool equipment, pumps, and spas, as applicable.

Green Globes Multifamily Performance Plus Existing Buildings Minimum Requirements

ENERGY MINIMUM REQUIREMENTS

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

1. Energy Performance

Meet the ENERGY STAR® Portfolio Manager Path or the Energy Consumption Savings Path if not ENERGY STAR eligible and document the energy savings.

1.A ENERGY STAR Portfolio Manager Path

Input energy use and building characteristics into ENERGY STAR® Portfolio Manager Path and complete Option 1 if eligible for an ENERGY STAR Score:

• Option 1: ENERGY STAR Score – For multifamily properties with 2 or more units – Achieve an ENERGY STAR energy performance score of 85 or greater using the Portfolio Manager program.
• Option 2: EUI Reduction – If not eligible for an ENERGY STAR Score
  Demonstrate 20% 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 20% or greater 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 and/or FEMP-designated energy efficient products and appliances (including clothes washers, dishwashers, and refrigerators), when such products and/or appliances are being replaced.

3. Energy Performance Monitoring & Tracking

Confirm that the local utility or on-site master energy meter(s) provide, at a minimum, aggregated whole-property 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

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.

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.

*Note on Whole Building Energy Consumption Data – An energy model may be developed if you don’t currently have 12 months of energy data to use as your baseline, including scenarios where it is not possible to access all tenant utility data.

The energy model must include the following systems:

• All mechanical systems;
• Domestic hot water systems;
• Lighting;
• Renewable sources of energy, as applicable;
• Pool equipment, pumps, and spas, as applicable.

Exception Policy – GBI reserves the right to issue ventilation, energy, and/or water exceptions on a case-by-case basis as needed for unique circumstances. Multifamily projects must still meet the 20% or greater energy consumption savings requirement, plus 15% or greater water consumption savings requirement.
