WHY?

• IMPORTANCE:

  • In developed countries, buildings account for 20–40% of total energy use (Guy R. Newsham, 2009)

  • Energy use also contributes GHGs to the atmosphere, almost 41% total in energy and building sector (IPCC AR4, 2007)

  • To reduce the emission, buildings need to use less energy in both their construction and operation, while still providing a satisfactory indoor environment for their occupants.

WHY?

• INTENT: use less, save more!

  • To support energy management and identify opportunities for additional energy savings by tracking building-level energy use.

  • applies to: ALL building categories

• Data Centers

• Hospitality

• Healthcare

• Warehouses and Distribution Centers

• New Construction

• Core and Shell

• Schools

• Retail

WHY?

• BEHIND THE INTENT

• Gaps between designed & actual performance

• Factors:

  • flaws in energy modeling

  • inadequate commissioning

  • inaccurate assumptions
    (e.g. occupants’ behavior)

  • lack of coordination during the transition from construction to operations

HOW?

• FIRST!

• To install electricity meter to track energy consumption by both the project building and any associated grounds.

Types of energy

• Regulated energy
  • for conditioning spaces, maintaining comfort and amenities
  • e.g. HVAC, lighting, water heating
• Process energy = unregulated energy
  • for manufacturing, industrial, or commercial process and others activities
  • e.g. computers, elevators and escalators, kitchen cooking and refrigeration, laundry washing and drying

STEP-BY-STEP GUIDANCE

1. Identify ALL Energy sources that serve building
2. Determine scope of utility company metering
3. Determine number, location & meters' type
4. Track energy consumption data
5. Share data with USGBC

• ​The project owner must commit to sharing energy use data with USGBC for five years in one of two ways:
  • USGBC-approved data template
  • Third-party data source

WHAT?

• Save energy, save $$.
• Certification Logos

KAHOOT!

WHY?

• INTENT: use less, save more!

  • To support water management and identify opportunities for additional water savings by tracking water consumption.

  • applies to: ALL building categories

    • New Construction

    • Core and Shell

    • Schools & Retail

    • Data Centers

    • Hospitality & Healthcare

HOW?

• FIRST!

• To install water metering to track water consumption by both the project building and any associated grounds.

Types of water

• potable/ non-potable?
  • drinkable or not
• black/grey/brown/white?
  • black water: toxic, with harmful bacteria (toilets' flush), must be discarded, can't be reuse
  • grey water=brown water: water from baths, showers, dishwashers and washing machines that can be reused.
  • white water = clean potable water 

STEP-BY-STEP GUIDANCE

1. Identify ALL Potable water end uses
2. Determine scope of public water supply metering, if applicable
3. Determine number, location & meters' type
4. Track water consumption
5. Share data with USGBC

• ​The project owner must commit to sharing water use data with USGBC for five years in one of two ways:
  • USGBC-approved data template
