Not Your Father’s Older Brother’s LEED:Energy & Commissioning Opportunities in LEED v4

Mark Gelfo, PELEED AP BD+C, LEED AP O+M, CxA, EMP

Director of Sustainability, TLC Engineering for Architecture

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

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

-Henry Ford

…it’s about performance.

LEED v4 is not just a faster horse….

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

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 RelocationSeattle, 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 1923.“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”.
