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

Design + Construction Case Study Example
Lessons Learned from Palandino: Palandino Office
 Manage expectations.
Relocation
Seattle, WA
LEED ID+C v4 Beta
 Preparation is essential.
 Don’t chase points.
Focus on performance.
 Engage the team.
 Take your time.
“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”.
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.
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.
