  1. Not YourFather’s Older Brother’s LEED: Energy & Commissioning Opportunities in LEED v4 Mark Gelfo, PE LEED AP BD+C, LEED AP O+M, CxA, EMP Director of Sustainability, TLC Engineering for Architecture

  2. What are we going to talk about? The CxA and EMP’s Opportunities, Roles, and Impact: • Designing High Performance Buildings • Commissioning • Measurement & Verification • Energy Auditing • Existing Building Cx At the conclusion of this session you will be able to: • Understand the new requirements of LEED v4 in general, and specifically as they apply to commissioning, retro-commissioning, and energy auditing • Understand the CxA’s and EMP’s Role, Responsibilities, and Opportunities on a LEED v4 Project (NC & EB O+M) • Be able to implement the Cx, Retro-Cx, and Energy Auditing Credit Requirements in multiple LEED v4 rating systems • Learn from the lessons learned from the LEED v4 beta projects and early projects in the v4 rating system

  3. How did we get here? Years in development Public comment periods Beta Projects USGBC Voting Membership Approval 4 6 120 86% • Launched at Greenbuild Philly last November • LEED 2009 available for new projects thru June 2015

  4. “If I had asked people what they wanted, they would have said faster horses.” -Henry Ford

  5. LEED v4 is not just a faster horse…. LEED v3 LEED v2 LEED v4 …it’s about performance.

  13. Constructing High Performance Bldgs in LEED v4 Who can be the CxA? • Experience on 2 similar size/scope projects • Fundamental: Owner, independent consultant, employee of the design or construction firm not part of the project, or disinterested subcontractor • Fundamental: <20K sf can be member of design team or Contractor • Enhanced: Owner, independent consultant, or a disinterested subcontractor • Reports findings directly to Owner Expanded Commissioning Scope in LEED v4 “….as they relate to energy, water, indoor environmental quality, and durability”

Constructing High Performance Bldgs in LEED v4 BD+C EA Prerequisite: Fundamental Cx & Verification What’s different? • List of 12 things CxA does • ASHRAE Guideline 0 & 1.1 • Envelope included in OPR, BOD, & Design Reviews • CxA on board by end of DDs • Prepare & Maintain Facilities Requirements & OM Plan • Design Review • Elec & Plumbing Scope Expanded

  15. Constructing High Performance Bldgs in LEED v4 BD+C EA Credit: Enhanced Cx & Verification What’s different? Option 1 • Path 1: (3 points) • Enhanced Cx, similar to LEED 2009 • Added Seasonal Testing • Added Re Cx Plan • Path 2: (4 points) • Path 1 + Measurement & Verification of Energy & Water Systems Option 2 • Envelope Cx (2 points) • Don’t have to do Option 1 to earn Option 2 • Path 2: Monitoring-based procedures to measure, evaluate & assess energy and water consuming systems. Include in Cx Plan.

  16. Design + Construction Case Study Example Lessons Learned from Palandino: • Manage expectations. • Preparation is essential. • Don’t chase points. Focus on performance. • Engage the team. • Take your time. Palandino Office Relocation Seattle, WA LEED ID+C v4 Beta Paladino was surprised to find its tenant improvements would qualify for only a silver rating under the new LEED version, not a platinum as it would under the old version. “Our internal commissioning team is using the monitoring requirements of LEED v4 to create a learning lab in our office, routing waste heat from the servers into the occupied office and exploring how carbon dioxide set points relate to natural ventilation needs”. http://www.djc.com/news/en/12062744.html Paladino’s offices have operable windows and steam heat. The 11-story building was completed in 1923.
