“LL87 requires buildings 50,000 gross square feet or more
to undergo an energy audit once every 10 years, along
with retro-commissioning to "tune up" the building's
existing energy systems and ensure efficient operation. “

“LL88 requires 50,000 gross square feet or more, non-residential
buildings to upgrade lighting to meet current New York City
Energy Conservation Code standards, and to install electrical
sub-meters for each 10,000 square feet non-residential tenant
space and provide monthly energy statements”
Deadline for compliance is January 1, 2025
Note: in particular, the code includes requirements for occupancy
and/or vacancy sensors and daylight harvesting

“Total Building Commissioning is a systematic process of assuring by
verification and documentation, from the design phase to a minimum
of one year after construction1
, that all facility systems perform
interactively2
in accordance with the design documentation and intent,
and in accordance with the owner’s operational needs3
, including
preparation of operation personnel4
.”
New Buildings:
General Services Administration/GSA
Total Building Commissioning/TBCx
Parallels with quality management:
1. TBCx assures that best industry practices are used cradle to grave
2. The building must be handled as a network of interactive systems
3. TBCx is driven by Owner’s Project Requirements and Design Intent
documents
4. TBCx includes operators development

“Design Stage commissioning activities serve to ensure that the Owner’s
Project Requirements for items such as energy efficiency, sustainability,
indoor environmental quality, fire protection and life safety, etc. are
sufficiently defined and adequately and accurately reflected in the
contract documents.”
Incorporate commissioning in the Architect/Engineers and Construction

17. GSA TBCx – Construction
Stage
“The Commissioning Team collaborates during the Construction Phase
to verify that systems and assemblies operate to validate that the
Owner’s Project Requirements are achieved. The two overarching goals
of this phase are to assure both the level of quality desired and the
requirements of the contracts are met.”

Post-Construction Stage
“Systems, assemblies, equipment and components will tend to shift from
their as-installed conditions over time. In addition, the needs and
demands of facility users typically change as a facility is used. The Post-
Construction Stage allows for the continued adjustment, optimization and
modification of building systems to meet specified requirements.”
Perform deferred and seasonal testing
Re-inspect performance before warranty end

Energy Efficiency Programs
Energy Audits*
Retro-Commissioning/RCx*
Continuous Commissioning (continuous systems improvement)
Building re-tuning (limited scope retro-commissioning focused
on control systems sensor checking/replacement, set-points
validation and system calibration)
* Energy audits identify opportunities for efficiency improvements
in an existing building and one of these opportunities is
frequently the need for a building “tune-up,” or retro-
commissioning (but, historically, energy audits tend to focus on
capital investment)

Collect all documentation including Owner’s Project Requirements,
operating manuals, installation schedules, blueprints, maintenance
records, and previous audit reports

22. Building Energy Efficiency
Main Tenets
Consume energy only when it is necessary (if you don’t use it,
turn it off).
At any given time, consume only the energy that is necessary
(match capacity to demand, typical issues with oversized
equipment).
Use high efficiency equipment and maintain it well.
Use a Building Automation (or Management) System to achieve
systems integration.
Energy use = equipment consumption x hours of operation
Hydronic Boilers
Modulating Control

23. Building Energy Efficiency
Typical Issues
Schedule: equipment is running when there is no demand
(especially HVAC, lights and plug-in loads)
Systems:
Untrained personnel.
Oversized equipment (boilers, fans, pumps).
Inefficient equipment.
Malfunctioning controls (dead sensors, out-of calibration
controllers, wrong set points, manual bypasses).
Inadequate maintenance (run to failure, cleaning, lubrication,
alignment, filter replacement, parts replacement, etc.)
High electricity demand
Poor energy purchasing practices
Combustion

24. Building Energy Efficiency
Typical Issues
What is the most common and most commonly neglected EEM?
Quality and Building Energy Management Moreno Tagliapietra – © 2013 24
Preventive maintenance!
A preventive maintenance program requires an exhaustive
equipment inventory, the collection of all related documentation
- manuals, installation schedules, blueprints, previous
maintenance/repair records, etc. -, an overhaul of
underperforming equipment, and then the proper maintenance
program including the collection and trend analysis of history
records

Final Words
Quality and Building Energy Management Moreno Tagliapietra – © 2013
As every professional promoting (positive) change in
his/her organization can tell you, if building ownership and
management are not on-board, achieving code compliance
is an uphill battle and more proactive energy efficiency
initiatives outright impossible
For your EEM proposals to have a chance of being taken
into serious consideration, present your case with an air-
tight evaluation of life cycle costs and savings
