IToward this objective,and in accordance with our proposed scope of work,FPM has performed the following tasks: 1. Conducted a visual survey of the facility and the existing conditions relative to the existing HVAC systems. I2. Interviewed site personnel relative to the HVAC systems. 3. Evaluated existing conditions and determined the necessary corrective measures. I4. Identified recommendations relative to the HVAC systems. I5. Prepared estimates of the construction costs of the appropriate corrective measures. FINDINGS AND CONCLUSIONS j Based upon our investigation,the existing HVAC systems are inadequate,deteriorating,inefficient I and have exceeded their expected useful service life per ASHRAE guidelines. Based on our visual observations, we have identified certain significant conditions relative to the I existing HVAC mechanical equipment. The following is a summary of our findings and conclusions: I 1. All of the major cooling and heating equipment appears to be original(25 years old), in fair to poor condition and have exceeded their expected useful service life. I 2. The existing components are prone to frequent failures that necessitate repairs. Many components are corroded and currently in need of replacement. I3. The existing cooling units do not have sufficient capacity to satisfy current peak cooling loads. I4. The main boiler is significantly oversized,thereby not operating in its best ranges of energy efficiency. 5. The existing systems are not designed to current energy efficiency standards and ventilation philosophy. i FPM I RECOMMENDATIONS We studied several alternatives to correct the identified problems at this complex. Based on practicality and economic comparisons, we recommend that the existing HVAC mechanical equipment be removed and replaced with new, efficient HVAC equipment as follows: 1. Two new dual fuel sectional boilers which meet New York State energy efficiency ' standards. ' 2. New high-efficiency split-system DX cooling units with hydronic reheat coils. 3. New supply and return ductwork distribution system with positive outside air ' ventilation and VAV zoning controllers. 4. New hydronic components for the new hot water heating system. ' 5. A new microprocessor-based controls system. ' We estimate the cost for the foregoing recommended new HVAC system to be in the order of $300,000. Other alternatives were evaluated but not recommended for several reasons including:impracticality ' of application,current technology,cost,and disruption to staff operations. The alternative systems evaluated but not recommended included: 1. Replacing existing HVAC equipment in kind. ' 2. Packaged gas-fired heating/cooling units. Discussions and analysis for these alternative systems are presented in the body of the report herein. 1 I I ii FPM i 1 SECTION 1.0 1 INTRODUCTION 1. Purpose of Report Fanning, Phillips and Molnar (FPM) has been retained to evaluate the condition of the existing heating, ventilating and air conditioning (HVAC) systems in the East and West wings of the Southold Town Hall complex. Recommendations for corrective measures were also requested and formulated. 2. Description of Existing Systems a. Construction of Building The Southold Town Hall building is a one-story structure with a basement. The ' building consists of a 4,400 sq.ft. east wing original structure and a 9,500 sq.ft.west wing added in 1976,with north,south,east and west exposures. Based on our visual survey of the east wing the walls are constructed of aluminum siding, wood sheathing, fiberglass batt and sheetrock. The typical construction material for the roof consists of wood sheathing,batt insulation and asphalt shingles. The windows are thermopane. An unheated full attic exists above the entire structure. ' b. Boiler Plant The existing case iron sectional boiler is a model 686 manufactured b 1 Y the Weil Mclain company. The general condition of the boiler is poor with evidence of moderate to severe corrosion on most surfaces. The air vent fittingon the boiler is severelycorroded and non-functioningand there is no in-line air separator installed in the hot water piping. This has lead to a chronic air bound problem within the closed piping system which requires frequent bleeding of trapped air by the maintenance supervisor. The boiler is energized by an aquastat to maintain 200°F hot water supply temperature. The oil fired burner is manufactured by the Powerflame company and rated at 2.5 GPH minimum and 11.8 GPH maximum for a net heating capacity of ' 1,008,000 BTUH. No model number could be ascertained from the burner. 1 There is no formal chemical treatment program for the heating water which has led to seriously corroded piping throughout the system. I -1- FPM I c. West Wing Cooling Plant The reciprocating chiller located in the basement mechanical room is a model P g CCUA-1506-MA manufactured by the Trane company and rated at 180,000 BTUH ' of cooling capacity. The visual appearance of the chiller is good, however, it has exceeded its expected useful service life of approximately 20 years according to the American Society of Heating, Refrigeration and Air Conditioning Engineers I (ASHRAE). The remote air-cooled condenser for the chiller is a model CAUA- 2006-OB and is located outside adjacent to the building. The same comments as to I the condition of the chiller apply to the condenser as well. Computer generated cooling loads provided in Section 5.0 reveal that this 180,000 BTUH chiller is undersized and will not satisfy the 235,177 BTUH cooling load that exists in the west wing zone. 11 I The modular air handler serving the basement accounting area is a Trane Model L-3 I with a 72,000 BTUH chiller water cooling coil and a 72,000 BTUH hot water coil. The air handler serving the first floor assembly area is a Trane model L-6 with an 88,000 BTUH chilled water cooling coil and 72,000 BTUH hot water heating coil. Both air handlers are in fair condition as observed visually. The outdoor air intake dampers were closed by the maintenance personnel in an effort to eliminate the foul smell emanating from a nearby waste vent. The hot water and chilled water pipes are III severely corroded within the mechanical equipment room and likely fouled. It appears that asbestos insulation was used on pipe fittings. The asbestos is not encapsulated in several areas and should be tested for asbestos containing materials. IComputer generated cooling loads in Section 5.0 indicate that the 88,000 BTUH cooling coil serving the first floor assembly area is undersized and will not satisfy the I 92,907 BTUH cooling load. d. East Wing Cooling Plant IThe reciprocating chiller with remote evaporator located in the basement mechanical room is manufactured by York International and serves the east wing. No model ' number was available, however, FPM engineers estimate the cooling capacity at approximately 60,000 BTUH. The computer generated cooling loads of 101,200 BTUH for the east wing zone exceed the 60,000 BTUH capacity of this coil thus Imaking it undersized as well. This chiller is in poor condition and is reportedly prone to malfunction. The ' evaporator has been corroded to the extent that chilled water leaks from several fittings. The 3-way control valve is severely corroded and its control wiring is exposed as if it were pulled out by hand. The chilled water pump is in fair condition, Ibut should be supplemented with a secondary back-up pump. 1 -2- FPM r I It is reported that the air handler serving the basement offices is not used by the Ioccupants because of unsatisfactory heating and cooling performance. The controlling thermostat does not appear to energize the air handler. The unsatisfactory Iperformance of the air handler is attributed to the following observations: 1. The non-functioning thermostat. I 2. Relocated supply diffusers that do not distribute conditioned air to current occupants. 3. Various office layout changes that now require rezoning of existing Iheating/cooling systems. e. Perimeter Fan Coil Units IThe perimeter fan coil units are comprised of a heating/cooling coil and fan with thermostat and speed switch. The speed switches were not operable on several fan I coil units. It was reported that the fan coil units are subject to frequent malfunctioning mainly due to the air bound problems noted previously. The unit located in the building department is currently not operational and has been I supplemented by a window cooling unit. The fan coil units provide no means of supplying ventilation air to the occupants. If. Miscellaneous Two 24x24 fixed combustion air intake openings exist on the outside wall in the 1 Boiler Room. National and local codes require two combustion air intake openings each sized for one sq.in.per 4,000 BTUH of burner input,placed near the ceiling and floor of the boiler room. These openings must have motorized dampers interlocked Iwith burners to open when burners are energized. The existing masonry chimney is original and should be inspected to determine I suitability for future usage. One 24,000 BTUH split system DX BTUH cooling unit serves the west wing basement computer room. This unit was installed recently and appears to be in good condition. I I I 1 1 1 -3- FPM 1 I ISECTION 2.0 ALTERNATIVES 1 In Section 1.0 we have reported that the existing heating and cooling systems have been identified as deteriorating, inefficient, deficient in design and installation, ineffective and beyond their 1 expected service life. The following subsections discuss the alternations studied to alleviate these problems. 1 ALTERNATIVE NO. 1 -Replacement of existing Boilers, Chillers,Air Handlers and Fan Coil Units 1 The replacement of the existing boiler, chillers, air handlers and fan coil units with those of higher capacity was considered. Although this alternative seems at first the least disruptive to staff operations, the poor condition of the piping system deems it necessary for replacement also. The 111 need to replace the piping system throughout the complex and the associated architectural modifications required would indeed be disruptive and cost prohibitive. 1 ALTERNATIVE NO. 2 - Packaged DX Cooling/Gas Fired Heating Units This alternative consists of installing packaged DX cooling/gas fired heating units outside the building on grade. New supply and return distribution ductwork will convey conditioned air to each 1 office. This alternative presents several problems. There is no practical means of routing ductwork to the basement. There would be no form of reheat for the perimeter zones with the exception of costly electric reheat. Lastly,the installation of ductwork would adversely impact the aesthetics of 1 the exterior of the building. ALTERNATIVE NO. 3 -New Boiler and DX Split System Units with Reheat 1 This alternative proposes to install a new fuel fired oil/natural gas boiler and burner(provided that LIPA can supply a sufficient amount of natural gas service), new high efficiency split system DX 1 cooling units with hot water reheat coils and a new ductwork distribution system to supply conditioned air and a proper amount of outside air throughout the complex. 1 The new sectional boiler and its associated air separator devices and pump set will be coupled with stand along microprocessor-based controller which will provide burner sequencing to match the heating load as outdoor conditions change. 1 The boiler plant will supply hot water to the new reheat coils in each zone. 1 New air handlers with DX cooling coils and hydronic preheating coils will be located in existing mechanical equipment rooms and the attic space as necessary. The associated condensing units will be set on grade outside the building. A new insulated supply and return ductwork distribution 1 system will be routed throughout the attic space and basement ceiling to convey conditioned air to all zones. Zoning will be accomplished with the use of variable air volume(VAV)controllers with hydronic reheat and independent electronic thermostats. The split systems units will provide the necessary ventilation air throughout the building to supply with ASHRAE standards for indoor air 1 quality. 1 -4- FPM 1 I ISECTION 3.0 CONCLUSIONS AND RECOMMENDATIONS A. Conclusions Based upon our investigation, we have identified significant conditions relative to the existing HVAC systems. I 1. The existing components are approximately 23 years old, beyond their expected useful life,prone to frequent repairs and not utilizing contemporary energy efficient equipment. I2. The existing cooling units do not have sufficient capacity to satisfy current peak cooling load requirements. I3. Current ventilation philosophy is to provide positive fan powered outside air into occupied spaces. Most of the occupied spaces in the Town Hall building do not have I this ability. B. Recommendations FPM engineers has analyzed the various alternatives mentioned in Section 2.0 to correct the Iidentified problems at this complex. Based on practicality and economic comparisons,we recommend Alternative No. 3,which is the installation of a new dual-fuel sectional boiler, split system DX cooling unit with hydronic reheat coils and ductwork distribution system twith positive outside air capability. The replacement of existing circulator pumps, air venting components,breeching,control valves and other related heating devices would also be required. The new heating and cooling units should be controlled by state-of-the-art energy efficient controls that will prolong the useful service life. The existing heating and cooling units,related components,breeching, etc.,would have to be removed from the mechanical rooms and legally disposed of. Additionally, code g Y P compliant safety and operating controls for the new boiler should be installed, as well as combustion air intake openings with automatic dampers. The institution of a regular boiler water treatment program is also recommended.
