Lower operating costs

Reduce waste sent to landfills

Conserve energy and water

Be healthier and safer for occupants

Reduce harmful greenhouse gas emissions

LEED and LEED EBOM

LEED Leadership in Energy and Environmental Design is a voluntary, consensus-based, market-driven program that provides third-party verification of green buildings. It is designed to:

LEED and LEED EBOM

LEED EBOM LEED for Existing Buildings: Operations & Maintenance is the tool for ongoing operations and maintenance of existing commercial and institutional buildings.

The intent of LEED EBOM is to certify the operations and maintenance of the building and create a plan for ensuring high performance over time.

The College Report Card surveys have shown dramatic increases on 52 green indicators since the publication of the first edition in 2007. For example, the percentages of schools that now have the following programs are:

LEED Payback

64% - Commitment to carbon emissions reduction (23% in 2006) 70% - Campus farm or garden (9% in 2006) 75% - Trayless dining (0% in 2006) 79% - Green building policy (22% in 2006) 95% - Sustainability committee (40% in 2006)

Energy/Utility savings

Operations

Grants or Matching funds

Student Engagement

Employee Retention

LEED Payback

Where LEED credits provide the most financial payback or impact on student experience

How it applies to campuses and real payback expectations

How it works, best practices, and financial rewards

Best Practices:

1. Build a Diverse Project Team

2. Set Appropriate Credit Goals

3. Perform a Building Audit

4. Pursue Certification Incrementally Beginning with Retro-commissioning

5. Pay For It

Know LEED EBOM

Understand alternative approaches to certification of new or existing buildings

Alternative Design Approaches

Department of Energy – Energy Star program Living Building Challenge State and Municipal Regulations Green Codes

“The systematic discovery, documentation, review, and improvement of energy operations through no/low-cost savings opportunities that match building performance to current functional requirements.”

Retro-Commissioning

Typical Savings Opportunities

Optimizing building systems and schedules through BAS Optimizing chiller and boiler operations to better match building

load conditions Reducing ventilation in over-ventilated areas Fixing ventilation dampers that are open when they should be

closed, or vice versa Decreasing supply air pressure set-point and system rebalancing Reducing supply air temperature and fan speed in air handling

units Aligning zone temperature set-points to match the building’s

actual operating schedule Operating equipment only when building is occupied or when

equipment is needed

Retro-Commissioning Program: Public Sector

Building Requirements

More than 5 years old

Exceeds 150,000 sq. ft.

Functional Building Automation System (BAS)

Minimum of guest access for the Retro- Commissioning Service Provider (RSP)

Retro-Commissioning Program: Public Sector

Client Requirements

Financial commitment for implementing (equipment/internal or external labor) Retro-Commissioning Measures (RCMs)

Decision made post-Planning, Investigation, and Recommendation Phase

18 month or less payback

$10,000 – Public

Commitment to active involvement in the RCx process:

Facility Owner and Staff

Active involvement includes:

Providing access to the facility

Providing time for facility personnel to interface with the RSP

Providing and assisting with the reporting, and collection of data pertaining to the facility RCx

Application Phase (Approx. 1 Month)

Planning, Investigation and Recommendation Phase (Approx. 3-5 Months) Evaluate function, sequencing, and scheduling of major systems

Interview with facility operation staff Set up BAS trends Spot check equipment on BAS Review as-built drawings

Identify RCMs Quantify energy savings

BAS trend data Spot measurements Data logging

RSP Deliverable/Scope of Work document Detailed RCM information and calculations Summary of data acquisition plans and results Energy and cost savings calculations for each RCM Implementation details including project cost Verification plans

Retro-Commissioning Program: Public Sector

Implementation Phase (Approx. 2-10 Months)

As the customer approves RCMs, the implementation team will perform the scope of work associated with the relevant measures

Implementation of the RCMs is the responsibility of the customer

The RSP will provide technical support as needed during this phase for the customer to implement the RCMs

The implementation team:

Facility engineers

Operational staff

Controls, mechanical, and/or electrical contractors

Retro-Commissioning Program: Public Sector

Verification Phase (Approx. 2 Months)

Inspect RCMs for installed equipment and controls modifications

Set up/collect trends depending on RCM

Conduct functional test depending on RCM

Perform spot measurements

Revise energy savings calculations as necessary

Final Verification Report

Final documentation of RCx process for implemented RCMs

Summary of completed RCMs

Final energy and cost savings

Final project cost and simple payback
