Library HVAC Upgrade 
1
The Waterford Library's HVAC systems are obsolete and in need of replacement. The current systems were installed in multiple phases
between 1965 and 1999. They are past their useful operating life and require frequent maintenance. Silver-Petrucelli and Associates
completed an engineering study in 2018 (FY'18 CIP) that evaluated the systems and provided recommendations for improvements. The
attached report details their assessment of existing conditions and options for replacement. Option 1 was chosen as the most cost
effective solution that would best suit the needs of the Library into the future. The cost of Option 1 was quoted at $1,034,000. Silver
Petrucelli also provided a quote to assist the Town in preparing specifications, bid documents, and construction oversight. The cost for
this service was quoted at $15,200. The request for the project, based on the August 2018 study, was submitted for FY'20 CIP at
$1,049,200 and deferred to 
FY'21. With the deferral, the vendor recommended an additional 3.5% - 4% increase in costs ($42,000)
bringing the FY'21 request to $1,091,200. In November 2019 the library was award a CT Public Library Construction Grant and as per
the grant guidelines the town has 3 years (November 2022/FY'23) to secure local funding . The first selectman recommends spreading
the project over three years with the first appropration of $200,000 approved in 
FY'21. The $250,000 grant will offset the total CNR
appropriation and absorb any additional cost increases.
Study and recommendations complete.
Town project (P&Z, DPW) to work with Eversource to extend gas line down Rope Ferry Road.
Since FY'07 repairs to library's main HVAC equipment, 4 furnaces and 2 A/Cs, and the engineering study/recommendations have cost
over $80,000 (see attached). Repairs have been increasing in frequency and cost as the systems age and deteriorate. The upgrade will
result in energy efficiency, reduced energy consumption and reduced costs of repairs, parts replacements, etc. The conversion to gas
from fuel oil will result in not only monetary savings but also provide a cleaner, greener system. Also, but not quantifiable, is the
positive impact on customer service with fewer incidents of no or insufficient heat and/or AC.
This library has received a State Public Library Construction Grant for $250,000 for this project. Copies of the award letter, grant
application and supporting documentation are included. As per the grant guidelines the library has until November 2022/FY 2023 to get
local funding in place.
Silver Petrucelli report and quotes are included. Also included are the State Library Construction library's state construction grant

Section | - Executive Summary
The services of Silver / Petrucelli + Associates (S/P+A) have been secured by the Town of
Waterford, Connecticut to provide an engineering assessment of the heating, ventilation and air-
conditioning (HVAC) systems serving the existing 
Waterford Public Library, located at 49 Rope
Ferry Road.
This report of our investigation and study describes the existing conditions and proposed HVAC
system improvements required to provide adequate space comfort, energy efficiency and
improved air diffusion Control for the Public Library. The current building 
HVAC systems serve
the Town's library space environment needs; however, comfort issues are now the norm,
concerns over indoor air quality ((AQ) and system performance have beset the building, most
notably in the addition stacks, almost from the onsct of HVAC systems’ installations,
This report was prepared by S/P+A of Hamden, Connecticut, an architecture, engineering and
interior design collaborative specializing in municipal town planning, historic restoration, master
planning and design:
The collected data was organized and appears in sections of this report in the form of existing
conditions summary, recommendations, conclusions, an opinion of probable costs for proposed
renovations, existing conditions photographs and a list of current applicable codes.
APPLICABLE CODES
Waterford Public Library Building HVAC Study
Waterford, CT 
Siver/Petrucelli & Associates, inc. ©
Page 2
Page 8

The proposed upgrades require that the building be brought up to full current code standards. The
codes to which the mechanical systems have been evaluated include:
e 
Connecticut State Building Code (CSBC) with 2016 Connecticut Supplements
e 
2012 International Building Code (IBC)
e 
20]2 International Mechanical Code (IMC)
e 
2012 International Plumbing Code (IPC)
e 
2012 International Energy Conservation Code (IECC)
e 
2014 NFPA 70 National Electric Code (NEC)
Any work done to the building will need to be performed to the Code cycle that is in force at the
time; Connecticut is expected to be updating the Codes effective October 1, 2018, to the 2015
ICC Compilation and is anticipated to enact the next level of Codes every three years, thereafter.
PROJECT OBJECTIVE
The primary objective of this report is to provide the Town with an assessment of the present
condition of existing equipment and systems serving the Public Library, address comfort and
indoor air quality (IAQ) concerns, analyze equipment capacity and provide a preliminary opinion
of probable costs for any related modification options that may be considered. The existing oil-
fired equipment serving this building are operating beyond their useful service life expectancies
and, in many cases, are incapable of maintaining setpoints related to occupant comfort within
these spaces. For these reasons, natural gas-fired rooftop and central station air handling
equipment is proposed. The new units are proposed to be gas-fired since natural gas line
installation has been proposed by the Town and is nearly underway on Rope Ferry road in front
of the library. In addition, because of their ability to move larger quantities of air — an aspect
which would alleviate distribution concerns in the stacks and areas with high ceilings — and
temper large quantities of ventilation air, these units are the most suitable choice. Other systems,
such as the split-ductless, variable refrigerant volume (VRF) type system, most notably
recommended for the recent HVAC upgrades at the Town Hall and Youth Services Bureau
Building, were not considered due to their inability to overcome the distribution and ventilation
quantity issues. When confronted with these exact performance drawbacks at the Town Hall -
namely in the Auditorium - gas-fired rooftop equipment was the system of choice there as well.
Lastly, we performed schematic-level, computer block-load heating and cooling calculations to
compare present building envelope loads to what could be anticipated upon the replacement of
the original windows by incorporating modern, “state-of-the-art” replacement window models.
The results are eye-opening and substantiate the rule of thumb stating that window replacements
of this type can see payback periods of five (5) years or less.

This report was developed with the input of facility staff, maintenance personnel and visual
observations of the existing facilities by our engineering staff and review of available existing
conditions drawings and records. Our directive was to develop a report wherein a qualified
Design-Build Contractor shall be able to understand the recommended systems being considered
and successfully begin the processes of designing and budgetary pricing, leading to
commencement and installation, with the understanding that all work to be performed will be
done while the building is still both occupied and functioning in its capacity as the Town Public
Library.
SP+A would especially like to thank Ms. Roslyn Rubenstein, Director of the Library and Mr.
Michael Miceli, Building Operations Manager for their extensive contribution of time, data,
input and access, and to the staff that provided their day-to-day experiences with the existing
environmental conditions — both positive and negative.
Section II - Existing Conditions
In 1965, the Town built the “New” Public Library at its current location, which utilized oil-fired
equipment for heating and ventilation of the building. In 1975, an addition was built to expand
the library and its services to the community. The 1975 addition included roof mounted, oil-fired
HVAC equipment as well. In 1976 mechanical modifications were done to the addition. New
mechanical equipment was added in 1999 to serve the new addition as well as a portion of the
existing building spaces.
Public Library Building Systems
Space heating and cooling for the building is provided by oil-fired equipment located in
the basement, as well as from one oil-fired, air handling unit on the roof. The other rooftop
mounted unit (RTU) is for cooling-only and utilizes direct expansion (DX) refrigeration.
Basement oil-fired heating and ventilating (H&V) units were installed in 1999 and are
approaching the end of their useful life — close to twenty years. The basement units are
manufactured by Jackson and Church and the York Corporation. It appears that the intent of
these units was to offset perimeter heat losses, while utilizing the existing RTU’s provide the
space conditioning for the interior portion of the library. The basement H&V units do not have
cooling capability. Ventilation air is supplied to all the units through a wall-mounted louver
connected to a common vent which each unit draws from. Fresh air is then distributed throughout
the facility by the air handling equipment located in the basement and on the roof via ductwork
serving the space.
The RTU’s are either mounted on curbs or steel dunnage on the existing roofs. Judging by their
current state these units are in poor condition and past their useful service life expectancy. The
complaints by occupants indicate that there does not seem to be enough airflow, particularly in
the stacks, and maintaining the thermostat setpoint is difficult.
There is an existing 2,000-gallon, underground fuel-oil storage tank located in the front of the
library. It was originally scheduled for replacement in 3 years, however with the proposed gas
Waterford Public Library Building HVAC Study
Waterford, CT 
Silver/Petrucelli & Associates, Inc. ©
Page 4
Page 10

service installation this could be moved up in schedule.
There are three (3) split air conditioning systems serving the library. One of the systems serves
the meeting in room in the basement, while the other (2) two serve the main staff office on the
Ist floor and the conference room in the basement level. Each of the indoor units have their own
grade-mounted condensing units. These systems, although functional at present, are
approximately 19-20 years in age and approaching the end of their useful service life expectancy.
Refrigerant for these systems are no longer in production per the Montreal Protocol refrigerant
phaseout schedule, and as a result these units will no longer be able to be serviced reliably.
Section III - Recommendations
Due to the age and poor condition of the existing mechanical systems and equipment serving the
building, full system replacement is the recommended course of action. With the prospect of
equipment replacement comes the opportunity to improve on the conditions within these spaces,
targeting existing [AQ concerns, meeting compliance with modern energy code requirements,
and improving the control of indoor environmental conditions within these spaces. Namely, it
provides the opportunity for the Town to:
¢ 
Operate these mechanical systems in a manner which promotes a clean and comfortable
environment in the most cost- and energy-efficient manner available
e 
Extend the building’s usefulness and allow for it to be a prime useable space in the
community for the benefit of current and future generations
e 
Alleviate airflow distribution, comfort and IAQ concerns while increasing energy
efficiency
Improved and simplified equipment service and maintainability
The ability to control and monitor operation, alarms, trend data, building occupancy
schedules and all system setpoints remotely from the internet and/or from a single
physical location, as desired by the Owner’s needs
The existing oil-fired equipment that is presently in place represents the lowest efficiency
systems available in terms of heating the library spaces. With operating efficiency in the range
of 80% to 86% - that’s when burners are new, and combustion is finely tuned — natural gas is the
clearer choice with efficiencies in the 92% to 98% range. In addition, the use of oil-fired rooftop
and/or central station equipment is easily the least commonplace choice of systems available.
This leads to a potential difficulty in finding replacement parts and qualified service personnel as
the systems age. And although VRF technology far exceeds the efficiency in even the best gas-
fired equipment, its physical limitations in air distribution and throw distance preclude us from
considering its use as the primary system of choice — not to say that its use in limited office-like
areas couldn’t be considered. However, the real benefit of VRF systems, the capability for
energy recovery between zones that are simultaneously in heating and cooling mode, would not
be as substantial a factor due to the building exposures available here for those types of spaces.
With replacement and modernization of the HVAC systems and the associated electrical and
controls infrastructure being the recommendation in this case, the manner in which this is to be
Waterford Public Library Building HVAC Study

Silver/Petrucelli & Associates, Inc. ©
Page 5
Page 11

accomplished should best reflect the building’s use, needs and current issues of concern. As
such, we have proposed three options for the HVAC system upgrade, as follows:
Option #1
Option #1 consists of rooftop-mounted, packaged air handlers with DX cooling and natural gas-
fired furnace sections.
Air Handling Equipment: The facility, will be served primarily by Variable Air Volume
(VAV), Air Handling Units (AHUs) located on the roof and in the existing basement
mechanical spaces. The AHUs will provide ventilation air as well as conditioned supply
air for space heating and cooling. Each AHU will be equipped with Supply Fan, Exhaust
Fan, Energy Recovery Heat Exchanger, and Merv 8 Air Filtration. The Supply and
Exhaust Fans will be equipped with variable speed drive (VSD), economizer, demand
control ventilation.
Primary air distribution will be supplied via a new ducted system from the AHUs to VAV
terminals located in the spaces served. The VAV terminals will be equipped with electric-
resistance reheat coils and will supply air to the secondary air distribution system
consisting of sheet metal ductwork and ceiling supply air diffusers. Return/Exhaust Air
from the spaces to the AHU’s will be via a ducted return air system.
Toilet/Locker Room Exhaust: Each Toilet Room and Custodial closet will be provided
with exhaust as required by the Building Code with the possible use of an Energy
Recovery Ventilator (ERV).
Automatic Temperature Controls/Energy Management System: The existing control
system should be updated to a modern, state of the art Direct Digital Control] (DDC) type
Energy Management system. The systems compatibility with existing systems will be
determined based on the Owner’s requirements. The communication protocol between
devices and equipment will be based on BACnet.
Electrical modifications will consist of connections to the VSD supply and exhaust fans,
electrical conduits, wiring and disconnects for two air handling equipment with VAV /
electric heat. Includes electrical hookups: toilet / locker room exhaust. BACnet & fire
alarm hookups as required by the mechanical / electrical drawings.
Plumbing modifications will consist of underground gas piping to the side of the building
where the gas company will install their meter. ‘The gas piping will then enter the
building to be connected to the natural gas-fired boilers. The proposed service entry
location for the new gas service is likely to be west of the front (Rope Ferry Road)
entrance pending gas utility provider approval.
Option #2
Option #2 consists of a hot-water boiler plant, hot water pumps, and packaged air handlers with
Waterford Public Library Building HVAC Study
Waterford, CT. 
Silver/Petrucelli & Associates, Inc. ©
Page 6
Page 12

DX cooling and hot water coils.
Heating Plant: The Central Heating Plant (CHP) will consist of natural gas-fired, high-
efficiency condensing boilers. Combustion air may be supplied directly to each boiler
with a dedicated duct or it may be supplied to the boiler room by combustion air fans.
The boilers will be vented outside either individually or into common venting utilizing
polypropylene piping. The boilers will have an automatic chemical water treatment
system and condensate drain neutralizing kits.
Hot water supply to the building will be by either inline primary or floor mounted hot
water pumps with variable speed drives (VSD’s) serving a reverse-return hot water loop.
Hot Water will be supplied to hot water coils in the air handling units, throughout the
building as well as to the VAV boxes and vestibule cabinet unit heaters.
Air Handling Equipment: The facility, will be served primarily by variable air volume
(VAV), air handling units (AHU’s) located on the roof and in the existing basement
mechanical spaces. The AHU’s will provide ventilation air as well as conditioned supply
air for space heating and cooling. Each AHU will be equipped with a supply fan, exhaust
fan, ERV, and MERV 8 air filtration. The supply and exhaust Fans will be equipped with
VSD’s, and the units will be capable of providing 100% outside air economizer and
demand control ventilation.
Primary Air will be supplied via a new ducted system from the AHUs to VAV Terminals
located in the spaces served. The VAV Terminals will be equipped with hot water reheat
coils and will supply air to the secondary air distribution system consisting of sheet metal
ductwork and ceiling supply air diffusers. Return/Exhaust air from the spaces to the
AHU’s will be via a ducted air system.
Toilet/Locker Room Exhaust: Each Toilet Room and Custodial closet will be provided
with exhaust as required by the Building Code with the possible use of an Energy
Recovery Ventilator.
Automatic Temperature Controls/Energy Management System: The existing control
system should be updated to a modern, state of the art Direct Digital Control (DDC) type
energy management system. The system’s compatibility with existing systems will be
determined based on the Owner’s requirements. The communication protocol between
devices and equipment will be based on BACnet.
Electrical modifications will consist of connections to central heating plant boilers,
VSD’s, hot water pumps and AHU’s VSD supply and exhaust fans. This includes the
electrical conduits, wiring and disconnects for two air handling equipment with VAV /
hot water reheat. Includes electrical hookups to toilet / locker room exhaust. BACnet &
fire alarm hookups will be provided as required by the mechanical / electrical drawings.
Plumbing modifications will consist of underground gas piping to the side of the building

location for the new gas service is likely to be west of the front (Rope Ferry Road)
entrance pending gas utility provider approval.
Option #3
Option #3 consists of a hot water boiler plant, hot water pumps, a chiller plant, chilled water
pumps and new air handlers.
°
Chilled Water Plant: A central chilled water plant will be provided, utilizing a high-
efficiency air-cooled chiller. The chilled water plant will have an automatic chemical
water treatment system.
Chilled Water Pumps will be either vertical, split-case type, end-suction type or inline
type, and will be equipped with VSD’s. Chilled water will be distributed via a chilled
water piping distribution loop feeding the cooling coils in all of the proposed air handler
units.
The Central Heating Plant (CHP) will consist of natural gas-fired, high-efficiency
condensing boilers. Combustion air may be supplied directly to each boiler with a
dedicated duct or it may be supplied to the boiler room by combustion air fans. The
boilers will be vented outside either individually or into common venting utilizing
polypropylene piping. The boilers will have an automatic chemical water treatment
system and condensate drain neutralizing kits.
Hot water supply to the building will be by either inline primary or floor mounted hot
water pumps with variable speed drives (VSD’s) serving a reverse-return hot water loop.
Hot Water will be supplied to hot water coils in the air handling units, throughout the
building as well as to the VAV boxes and vestibule cabinet unit heaters.

Primary Air will be supplied via a new ducted system from the AHUs to VAV Terminals
located in the spaces served. The VAV Terminals will be equipped with hot water reheat
coils and will supply air to the secondary air distribution system consisting of sheet metal
ductwork and ceiling supply air diffusers. Return/Exhaust air from the spaces to the
AHU’s will be via a ducted air system.
Toilet/Locker Room Exhaust: Each Toilet Room and Custodial closet will be provided
with exhaust as required by the Building Code with the possible use of an ERV.

system should be updated to a modern, state of the art Direct Digital Control (DDC) type
energy management system. The system’s compatibility with existing systems will be
determined based on the Owner’s requirements. The communication protocol between
devices and equipment will be based on BACnet.
¢ 
Electrical modifications will consist of connections to central heating plant boilers,
VSD’s, hot water pumps and AHU’s VSD supply and exhaust fans. This includes the
electrical conduits, wiring and disconnects for two air handling equipment with VAV /
hot water reheat. Includes electrical hookups to toilet / locker room exhaust. BACnet &
fire alarm hookups will be provided as required by the mechanical / electrical drawings.
¢ 
Plumbing modifications will consist of underground gas piping to the side of the building
where the gas company will install their meter. The gas piping will then enter the
building to be connected to the natural gas-fired boilers. The proposed service entry
location for the new gas service is likely to be west of the front (Rope Ferry Road)
entrance pending gas utility provider approval.
Additional Sustainable Design Considerations
Building Energy Management Systems (EMS)
An EMS provides a building owner with the ability to monitor, control, and adjust all HVAC
systems (along with plumbing and electrical systems, if desired) from a central or web-based
location. An operator workstation consisting of a personal computer and printer can be located
in the building, and this station could have the capability of remote access to the HVAC systems
via the internet, if desired. The owner can set occupancy schedules, adjust setpoints, and
monitor trouble/alarm conditions in an efficient manner with this tool. Features such as night
setback, holiday scheduling and weekend scheduling will be included to allow the system to
minimize energy expenditure during unoccupied periods. An alarm feature will be added, which
can remotely notify facility staff of any pre-determined alarm conditions needing to be
addressed.
Demand Controlled Ventilation (DCV)
DCV is a ventilation scheme used to ensure that adequate ventilation for a building’s occupants
while reducing excess energy use from unnecessarily over-ventilating the building or space. The
ventilation process requires a substantial amount of energy since outside air needs to be heated or
cooled to acceptable levels prior to distribution through the building. Energy is conserved by
controlling ventilation rates based on the actual number of occupants indirectly, by sensing
carbon dioxide (COz) levels as an indicator of occupant load. CO2 concentrations are
continuously monitored by a sensor, either located in the space or the return air ductwork, which
modulates outside air dampers through their full-open and -closed positions accordingly to
maintain CO2 concentrations below an established comparative baseline. This technique can be
applied throughout the building and is especially effective in high occupancy spaces which are
not continuously occupied. DCV can be easily implemented by the addition of sensors and
required programming when an EMS is utilized.
Window Upgrades

Page 15

S/P+A has additionally considered the architectural impact of upgrades to the existing Library
envelope on its heating and cooling loads, as well as the potential reduction in central system and
equipment sizing that could result from these upgrades. By changing the existing, original
“storefront” type fenestration, which has been technologically surpassed in recent decades by
more state-of-the-art, energy efficient storefront window assemblies having much higher U-
values, integral low-e coatings, inert gas infill, lower infiltration potential and improved long-
lasting thermal break enhancements. That being said, our current calculated block-load estimate
for the building presently results in 969,500 btu/H of heat required during design heating
conditions and roughly 55.0 tons of cooling during peak summer design conditions. The
installation of the improved fenestration could have the potential to reduce the Library’s heating
requirements to 513,000 btu/H and its cooling needs down to 40.1 tons — or 47.1% and 19.8%
reductions, respectively. Payback on this scale and scope of upgrade typically average around 5-
years or less, depending on the quality of the replacements.
Miscellaneous Sustainability Considerations
Refrigerants used in air conditioning systems will be hydrofluorocarbons having low ozone
depletion (ODP) and global warming potentials (GWP). Equipment will most likely use HFC-
410A or HFC-134a.
Premium Efficiency Motors will be utilized wherever their application is feasible and per the
latest enforceable energy codes, Capitol reimbursements and incentives are often available for
the incorporation of Premium and High efficiency motors, dependent on the motor size and
funding availability.
Use of daylighting and active lighting control through the EMS or a separate controller can
substantially reduce lighting energy loads, especially when used in conjunction with high
efficiency LED lighting and space occupancy sensors. Reimbursements and incentives are often
available for these types of upgrades as well.
Section IV - Conclusions
The Waterford Public Library Complex is a Town landmark which has served the community in
many ways, and for many generations. However, it will be important to take the proper steps in
preparing this building for its next cycle of use. With the history of IAQ and air distribution
concerns in this facility, circumstances indicate that HVAC system upgrade/ replacement and
associated electrical power and controls upgrades to support the HVAC, is both overdue and of
Waterford Public Library Building HVAC Study

Silver/Petrucelll & Associates, Inc. ©
Page 10
Page 16

the utmost importance for the Town as a part of maintaining the use of the facility into the future.
Other than the existing environmental conditions, this building remains useful and viable among
the Town’s assets. By taking full advantage of modern and state-of-the-art HVAC systems and
technology during this potential upcoming and timely upgrade, the Waterford Public Library can
support the current space use and any unforeseen space use reconfigurations that may be yet to
come. In doing this, the Town of Waterford can fully realize benefits including:
> Reduced energy usage resulting in lower fossil fuel consumption, lower combined energy
costs and a considerably reduced “carbon footprint”
> Leading by example in the realm of sustainability and environmental responsibility,
providing a successful case study for the Town’s students, taxpayers and residents to follow.
> Saving taxpayers money for utility costs and maintenance spending.
> Eliminating the need for expensive, materially wasteful and often disruptive newly-
constructed buildings and sites to take the place of existing, viable structures in need of a
partial overhaul. In doing so, the Town acts in the most environmentally sound (green)
manner by reducing the demolition waste of the existing building and the construction waste
of any new building(s).
> Ease of maintenance and accessibility for all future routine preventative maintenance
requirements.
The addition of new HVAC equipment, power and control wiring, piping, ductwork and
windows, along with the temporary annoyance of staff and Town Library patronage, will be
somewhat disruptive in the short term. But in considering the long view, this facility will benefit
from these brief overhauls and disruptions for many healthy, energy efficient and productive
years to come.
