To Lead or not to LEED? A No-Nonsense Approach to Sustainability Lourdes Gonzalez Director of Sustainability Adam Stribling Manager of Retro-Commissioning
Agenda What is LEED and LEED EBOM? Why choose LEED Design Alternative Design Approaches How can I save more energy and money? Retro-commissioning
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: Lower operating costs Reduce waste sent to landfills Conserve energy and water Be healthier and safer for occupants Reduce harmful greenhouse gas emissions Source: http://new.usgbc.org/
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. Source: http://new.usgbc.org/
LEED Payback 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: 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)
LEED Payback Where LEED credits provide the most financial payback or impact on student experience Energy/Utility savings Operations Grants or Matching funds Student Engagement Employee Retention
Know LEED EBOM 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
Alternative Design Approaches Understand alternative approaches to certification of new or existing buildings Department of Energy Energy Star program Living Building Challenge State and Municipal Regulations Green Codes
Retro-Commissioning 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 Program: Typical Savings Opportunities Public Sector 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: Building Requirements Public Sector 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) Energy Use Intensity (EUI) Demonstrates potential to produce significant energy savings through RCx Electricity Natural gas
Retro-Commissioning Program: Client Requirements Public Sector 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
Retro-Commissioning Program: Application Phase (Approx. 1 Month) Public Sector Application Content: Facility Information Building Automation System Equipment Details Energy Usage Information Renovation & upgrade projects Past, current, or planned Facility Staff availability As-built drawings Application available online: http://smartenergy.arch.uiuc.edu/ pdf/sedac_py5_(2012-2013)_rcx_program_application- 7-31-12-FINAL.pdf
Retro-Commissioning Program: Public Sector 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
Key Takeaways How does LEED and LEED EBOM position you to save money? Key elements to focus on when looking at LEED Design and the important benefits What are some Alternative Design Approaches to can help you reach similar goals How to leverage state funded programs to save more energy and money?
