1 Not Your Father’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: 1. Understand the new requirements of LEED v4 in general, and specifically as they apply to commissioning, retro- commissioning, and energy auditing 2. Understand the CxA’s and EMP’s Role, Responsibilities, and Opportunities on a LEED v4 Project (NC & EB O+M) 3. Be able to implement the Cx, Retro-Cx, and Energy Auditing Credit Requirements in multiple LEED v4 rating systems 4. 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  Launched at Greenbuild Philly last November  LEED 2009 available for new projects thru June 2015

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. Paladino’s offices have operable windows and steam heat. The 11-story building was completed in “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”.
