And we do it
ON TIME
OUR STORY
Our mission is simple – To create a
sustainable built environment that is
good for both your bottom line and the
natural environment.
Conduct operations in a comprehensible
manner to ensure efficient and effective
project completion.
Creating a sustainable clean environment
within your building leads to increased
building value, avoidance of fines, and
compliance to upcoming Local Laws deadlines.
We construct a time-frame that best suits
our clients schedule based on their facilities,
needs, operations, and maintenance.
ABOUT US
The Cotocon Group was founded in 2010 by Chief Executive Officer,
Jimmy Carchietta. We are a sustainable engineering consulting
firm committed to providing smart solutions for new and existing
infrastructure. Our priority is to support our client’s mission today
and vision for tomorrow.

3. 295 MADISON AVENUE
CREDITS EARNED
LEED + ENERGY STAR CERTIFICATION
43
The Cotocon Group (TCG) conducted an energy audit and retro-commissioning
as part of the LEED EBOM process to identify energy reduction and GHG
mitigation measures. Field verification/testing along with existing energy data
analyzation resulted in the discovery of energy conservation measures (ECM’s)
that would equate to $118,253 in NYSERDA rebate opportunities.
The building successfully received both ENERGY STAR and LEED
EBOM “Certified” recognition though the USGBC rating system.
The energy consumption reduction component of the LEED
project will continue to save the building owner 11.4% on
their utility bills annually.
The 295 Madison Ave building is one of the first NYC buildings to receive LEED-
EBOM (Existing Building Operations + Maintenance) Certification and reduce overall
energy use and greenhouse gas emissions.

4. THE LAUREATE
The Cotocon Group (TCG) audited The Laureate’s sources of energy
consumption, varied space use, and envelope to identify energy reduction and
GHG mitigation measures. Field verification allowed TCG to understand the
current facility requirements (CFR) to identify cost-effective improvements. By
comprehensively analyzing energy consumption data, TCG was able to calculate
and project carbon emission levels from present day through 2035, which
accounted for numerous scenarios of energy consumption change.
The Laureate Condominium, built in 2009, wanted to reduce energy costs and
was concerned about greenhouse gas (GHG) emission levels in relevance to the
brand-new New York City Carbon Emissions Limits law (Local Law 97 of 2019). With
308,707 square feet, 69 units, retail space, and parking space, the facility’s energy
consumption needed to be analyzed.

TCG and ownership are currently
implementing energy-saving, emissions
reducing measures to avoid any costly
future violations and begin saving on
energy costs immediately. Based on
TCG reporting and analysis, the client is
pursuing a Cogeneration Plant (a major
capital improvment), which will reduce
peak load demand by 38% and allow
the building to generate 28% on-site
energy.

5. 500-512 7TH AVENUE
Over the course of 6-months,
TCG identified and replaced
almost 300 steam traps resulting
in a new steam trap passing
rate of 92.5%. By increasing the
efficiency of the steam heating
system, ownership will capitalize
on an estimated $96,348.04 in
energy savings moving forward
each year. The return on
investment for this project was
under 1-year.
The Cotocon Group (TCG) conducted field testing an analysis to identify these
deficiencies and develop an efficient and cost-effective plan to solve this
energy problem. In order to maximize energy savings and minimize capital
cost expenditures, individual steam trap replacement was completed on-site
including optimization of overall steam system operation.
The 500-512 7th Avenue facility was experiencing substantial energy costs and heat
loss due to failures in the steam heating system. With 1,159,286 square feet., 1703
steam traps, and over 1800 radiator units, minor leaks and failed steam traps were
accounting for tenant thermal comfort issues, increased energy consumption and
low overall efficiency of the heating system.

6. THE LAUREATE
MARRIOTT AT PENN
SQUARE CENTER
We utilized building energy modeling to determine the percentage of responsibility
for electricity and natural gas costs in the daily operations of the integrated facility.
Building energy modeling was additionally utilized on a new tower addition for the
Marriott Hotel, which was under construction during the time of the project.
Determine the distribution of energy usage and cost between two parties that
share the existing facility (Marriott Hotel and Lancaster County Convention
Center, or LCCC), and accurately project how the addition of a new tower will
impact this cost distribution.
