MECHANICAL SYSTEM LIFE CYCLE ANALYSIS EXECUTIVE SUMMARY

Section 1.0: Executive Summary The Southborough Public Safety Complex is a new facility with an approximate area of 38,000 s.f. located in Southborough, MA. The new facility will house the police and fire departments with bays for vehicles and is intended for 24 hour operation. The goal of the mechanical lifecycle engineering economic analysis is to assess the performance of various mechanical systems in comparison to a baseline mechanical system. Each option is compared to the baseline system to determine the lowest combined savings over a 30 year cycle to determine the most advantageous system considering electrical costs, gas costs, maintenance costs, and initial construction costs. By comparison of each option to the baseline system, the option with the greatest total life-cycle savings is generally recommended. To further enhance controllability and overall system performance, additional options should be considered that will enhance year round temperature control and comfort at a possible marginal increase in capital cost.

Hot water primary pumping with variable frequency drives Direct digital controls throughout Section 1.2: Mechanical System Analysis Conclusion The variable air volume air handling unit system is selected as the baseline system since it is an ASHRAE Standard 90.1 baseline system that generally results in a low installed cost system. Unfortunately, the selection results in overall ownership costs that in some cases are higher when compared to the alterative systems primarily relating to the increased annual operating costs while also compromising the thermal comfort of the building. The option comparison of each alternative system to the baseline assesses the benefits of improved systems with potentially reduced combined operating costs and improved thermal comfort with the goal of selecting the system with the highest ownership savings over the 30 year study period. Annual electrical and gas consumption is calculated thru the results of a thermal dynamic heat transfer analysis utilizing Department of Energy (DOE-2)/eQuest software with all architectural data provided by Context Architecture. Utility cost data for electricity and natural gas is based on published data by the U.S. Energy Information Administration for the area. The rates are $0.16/kWh for Electricity and $1.20/therm for Natural Gas. The building envelope consists of the following insulation values: The roof has R-30 continuous insulation and the walls have R-15 cavity insulation. Windows have a U-Value of 0.30 and 0.47 S.C. The Building Life-Cycle analysis includes future worth of each system option considered using standard industry discount, inflation, and interest rates. The life cycle analysis program BLCC5 utilizes energy price escalation rates by the D.O.E. Energy Information Administration and the most recent FEMP discount rates. Our observations of the Mechanical System Payback Summary suggests that option two, an induction unit system, represents the most cost effective solution by yielding an approximate $527,876 savings over the 30 year study period with a one year discounted payback in comparison to the baseline system. Note: The values indicated above are based on energy modelling performed for system comparison purposes only. Our office strongly recommends adding a 30% safety factor to the calculated values of this report for budgeting purposes to account for potential variances to the actual operation of the building. Per ASHRAE Standard 90.1-2010: Neither the proposed building performance nor the baseline building performance are predictions of actual energy consumption or costs for the proposed design after construction. Actual experience will differ from these calculations due to variations such as occupancy, building operation and maintenance, weather, energy use not covered by this procedure, changes in energy rates between design of the building and occupancy, and the precision of the calculation tool.

Product Induction Units GARCIA GALUSKA DESOUSA Consulting Engineers, Inc.

For the energy efficient buildings of today and tomorrow Chilled Beam/Induction Unit 1-Way Blow Chilled Beam Technical Specifications American Owned and Operated

Chilled Beam/Induction Unit A Chilled Beam takes a source of primary air at a maximum inlet static pressure of 1 wc. It distributes this air through a bank of specially designed aerodynamic nozzles and discharges the air at a high velocity into a mixing chamber. This creates a differential pressure which enables a draw of room air across a coil. This imparts either sensible cooling or heating to the air as it passes over the coil. The primary air and induced air are mixed and discharged through a grille in a coanda effect air distribution at the ceiling. This air circulates throughout the room and is gently drawn back up through the return section of the Chilled Beam grille. Because the return air to the terminal is located at the ceiling and is moving so gently, dirt is not carried along with it and filters are not required to protect the coils. This eliminates the cost and labor required for this routine maintenance. Chilled Beams are extremely flexible and enhance the savings and effectiveness of primary air systems such as those using dedicated outside air. When using our Chilled Beams, the primary air system, which includes the dedicated outside air unit and the supply and exhaust ductwork, can be sized to handle only the required ventilation air. This reduces the size of the equipment and duct work making it easier to fit into a building space. This also reduces the energy required to supply the ventilation to the building. The total room air circulation is created solely by the induction principle within the terminal; therefore, there is no electric motor requiring an electric power source or maintenance for a fan and motor. As a result, the Chilled Beam is a very quiet and efficient way to provide comfort in a space. Model Q1 and Q1L 1-Way Blow Ceiling Mounted Induction Unit The Q1 and Q1L are ceiling mounted Chilled Beams that blow in one direction and are available in various configurations. They were primarily created for areas that require between 40 CFM to 100 CFM of ventilation air. The Q1 and Q1L units are available in 2- and 4-pipe configurations. The Q1 and Q1L are a perfect fit for office spaces, dormitory rooms, patient rooms, etc. They are also perfect for hallways and corridors and as a supplement to other Chilled Beam units.

For the energy efficient buildings of today and tomorrow Chilled Beam/Induction Unit 1-Way Blow Chilled Beam Technical Specifications American Owned and Operated

Chilled Beam/Induction Unit A Chilled Beam takes a source of primary air at a maximum inlet static pressure of 1 wc. It distributes this air through a bank of specially designed aerodynamic nozzles and discharges the air at a high velocity into a mixing chamber. This creates a differential pressure which enables a draw of room air across a coil. This imparts either sensible cooling or heating to the air as it passes over the coil. The primary air and induced air are mixed and discharged through a grille in a coanda effect air distribution at the ceiling. This air circulates throughout the room and is gently drawn back up through the return section of the Chilled Beam grille. Because the return air to the terminal is located at the ceiling and is moving so gently, dirt is not carried along with it and filters are not required to protect the coils. This eliminates the cost and labor required for this routine maintenance. Chilled Beams are extremely flexible and enhance the savings and effectiveness of primary air systems such as those using dedicated outside air. When using our Chilled Beams, the primary air system, which includes the dedicated outside air unit and the supply and exhaust ductwork, can be sized to handle only the required ventilation air. This reduces the size of the equipment and duct work making it easier to fit into a building space. This also reduces the energy required to supply the ventilation to the building. The total room air circulation is created solely by the induction principle within the terminal; therefore, there is no electric motor requiring an electric power source or maintenance for a fan and motor. As a result, the Chilled Beam is a very quiet and efficient way to provide comfort in a space. Model QLS 1-Way Blow Ceiling Mounted Induction Unit Model QLS units are 1-way blow, ceiling mounted Chilled Beams that are linear in dimension. The model QLS is 24 x 48 and is offered in 3 series: Series 24 is low capacity, Series 31 is medium capacity, and Series 38 is high capacity. These units have a 2-way grille which discharges on one side and returns on the other. They are available in various dimensions and configurations and can be custom designed for a specific job. They were primarily created for areas that require between 25 CFM and 200 CFM of ventilation air. QLS units are available in 2- and 4-pipe configurations. These units are a perfect fit for office spaces, dormitory rooms, labs, etc. They are also perfect as a supplement to other Chilled Beam units. These units have drain pans and can be designed to handle both sensible and latent loads in the occupied space.

Bulletin B-207G Bell & Gossett Series 1510 Centrifugal Pumps Technical Bulletin For hydronic heating and cooling systems, industrial, pressure boosting and general pumping applications High efficiency, low operating costs Easy maintenance Seal options Part of the Bell & Gossett Equipment Selection Program

Take away these seven standard features and you ll have a pump like everyone else s. TRUE BACK PULLOUT A B&G standard in design and construction. Ease in service is assured, while piping and motor remain undisturbed. Extended delays for repairs are virtually eliminated. INTERNALLY SELF-FLUSHING MECHANICAL SEAL This design is way ahead of its time. This unique seal design is proven in many years of service. It requires no special external flushing provisions, since the design provides for constant efficient flushing action internally. This standard feature ensures maximum seal face lubrication, heat dissipation and debris removal without vulnerable, external flush tubing. The internal flushing action passes two and a half to three times the flow over the seal faces compared to a few GPM for conventional, stuffing-box designed pumps. SOLID-FOOT MOUNTED VOLUTE All Series 1510 pumps are provided as standard with an integrally cast volute foot located directly beneath the pump volute. This integrally cast foot ensures that the alignment between the volute and motor assembly is maintained. Without solid support beneath the volute, the piping weight alone will cause distortion which can lead to premature failure of the bearings, shaft and mechanical seal. This feature is equally important on hot water applications. The Series 1510 volute foot provides a solid foundation and eliminates the deflections which would otherwise exist within an unsupported overhung volute during the normal thermal expansion of the system piping against the volute. COMPUTER CONTROLLED IMPELLER BALANCING 1510 impellers are balanced to HI/ANSI 1.1-1.5-1994 section 1.4.6.1.3.1, balance grade G6.3 standards. This method of computer balancing Impellers provides for quiet, efficient, vibration free performance. Diameters are computer selected at the factory to furnish assurance that your capacity requirements will be met. CENTER DROP-OUT SPACER COUPLING Unlike conventional jaw type or rigid style couplings, a center drop-out spacer coupling allows removal of the bearing frame and rotating element without disturbing the pump end pipe alignment or motor electrical connections. HEAVY DUTY, RUGGED BASEPLATE The Bell & Gossett fabricated heavy duty baseplate is supplied as standard on every Series 1510 pump. Unlike rolled steel and C channel baseplates, the Series 1510 baseplate provides a heavy duty saddle assembly, full seam welds, closed baseplate ends and an open top to provide ease of access for proper equipment grouting. ANSI/OSHA-COMPLIANT COUPLING GUARD The coupler guard complies with ANSI B15.1, Section 8 and OSHA 1910.219. The guard offers increased protection against potential injuries and is standard on all 1510 pumps. The guards include slotted viewing windows for easy inspection. 3

The four-way cassette-type unit is compact and recesses easily into a ceiling space so all you see is an attractive, flush-mounted grille. Beneath that elegant exterior is a powerful, high-performance machine with a built-in drain lift-up mechanism. The fan is engineered to provide optimum air distribution with minimal sound. Both styles can bring in outside air into your space, the PLFY- NBMU can also branch over to air condition an adjacent room. The PLFY-NCMU unit is specifically designed to fit within a ceiling grid for ease of installation. 32 PLFY-P-NBMU 37-7 /16 PLFY-P-NCMU 25-5 /8 Quiet operation These powerful indoor units are whisper-quiet, down to 29 db(a) for the PLFY-NCMU and 27 db(a) for the PLFY-NBMU. At only 8-3/16 in height and only 22-7/16 x 22/7/16 in width, the PLFY- NCMU makes accessing even the tightest of ceiling installations a possibility. The NCMU s grille is color-matched with the NBMU and blends in well with white drop ceiling tiles. Customize the airflow pattern to meet your needs The different airflow patterns provide the best solution for a variety of room layouts and airconditioning requirements. For extra versatility, you can select from two-, three-, or four-way airflow. Built-in condensate lift mechanism The drain piping of the PLFY-NBMU can be positioned anywhere up to 33-1/2 inches from the ceiling s surface, allowing for long piping and versatility. A built-in switch halts operation if an error with the pump occurs, ensuring that no water leaks from the unit. PLFY-NBMU The PLFY-NCMU model has a built-in pump that lifts condensation 20 inches from the ceiling s surface. The unit recognizes when there is a pump failure and safeguards against leaks.

Corner-pocket design simplifies maintenance and installation PLFY-NBMU allows access through the pockets equipped on all four corners of the grille to complete installation, maintenance work, and height adjustment. Easy maintenance, long-life filter The washable filter provides about 2,500 hours of use in a normal office environment before cleaning is needed. The PLFY-NBMU is also available with an optional multi-function casement that allows for additional ventilation air and better filtration. ADDITIONAL FEATURES FOR PLFY-NBMU MODELS Wider air stream Longer air outlets on the PLFY-NBMU unit deliver wider air streams for improved air distribution and energy savings. This feature means quieter air delivery with fewer drafts and great overall cooling and heating coverage. Previous Model Air outlet hole: 16-3/16 In. PLFY-NBMU-E Air outlet hole: 19-11/16 In. Auto Wave airflow feature (Heating Mode) In the Heating mode on the PLFY-NBMU, each air outlet vane operates independently, distributing warm air in multiple directions for better room heating. Independent vane motor control Each of the four vanes on the PLFY-NBMU can be set by the wired remote controller to operate independently to match the room layout. Specific vane settings include five fixed directions plus swing. Auto fan speed feature The PLFY-NBMU unit offers the choice from four set fan speeds, or auto fan speed, to ensure faster achievement of room temperature target. Auto fan speed mode allows the fan to adjust its speed based on the degree of differential between set point and room temperature. The i-see sensor accessory In addition to the return air temperature, the PLFY-NBMU four-way ceiling cassette with the field installed i-see sensor measures the floor temperature in real time, observing the room vertically for better management of sensible temperature (temperature felt by occupant). The i-see sensor measures the infrared rays generated from the surrounding wall and floor surface at an angle of 360. The infrared ray energy is converted into a temperature value. The i-see sensor rotates 90 slowly in five-second intervals for correct measurement of temperature to cover the full floor space. INDOOR UNITS Low Mid1 Mid2 High Auto 33
