4.2 HVAC Systems 4.2.a Heating Systems The 1951 portion of the building is heated by steam. The subsequent additions are heated by pumped hot water produced by a steam to hot water heat exchanger. The steam is produced by (2) Smith 28A-12 steam boilers with a total capacity of 4,706 MBH(each) at full load. They run in a lead/lag formation at an estimated 78% efficiency. Steam is circulated through the original portion of the building at 10 psi. The newer sections of the building both have hydronic heating systems. It is estimated that roughly 56% of the total school area is heated by steam vs. 44% heated by hot water. Currently, the school is returning steam condensate to a condensate return tank and mixing it with make-up water that feeds back to the boiler. A portion of the steam is converted to hot water via a tube and shell heat exchanger to heat the 1969 and 2008 portions of the building. Due to the inefficiencies of the heat exchanger (fouling and heat transfer losses), the overall efficiency of the heating system is reduced. Steam and hot water circulate throughout the building to provide heating to all spaces, classrooms, hallways, and the multi-purpose room. Heating in classrooms are provided by heating only unit ventilators which are controlled by pneumatic thermostats. Hallways are heated by a combination of ceiling and wall mounted fan coil units with thermostats located in the hallways throughout the school. There is one air handling unit (AHU) that serves a classroom that uses electric resistance. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. 4.2.b Cooling Systems The AHU mentioned above also provides 36,000 BTU/hr of cooling from a condensing unit (CU) located on the roof nearby the unit. Other air conditioning throughout the school is provided by window A/C units in classrooms and some offices. In general window A/Cs need to be moved year to year in the elementary school depending on if a student requires conditioned air due to allergies. This requires custodians to often remove a window to insert a piece of sheet metal or wood to support the A/C. There were 29 window A/Cs in total. Some Window units were not properly sealed on the edges and allowed outdoor air to infiltrate the building. Additionally, some of the units were quite old and could be upgraded to energy star equivalent units. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. 4.2.c Ventilation Systems


Every classroom in Lake Hiawatha Elementary School has a unit ventilator. Unit ventilators (UV) provide heating and ventilation to the classroom using hot water coils fed from the boilers. A small fan moves the air through the coil to provide heating. Modulating dampers control the amount of indoor recirculated air and outdoor air flow. The units are typically attached to an exterior wall which allows the unit to get ventilation air directly from the outdoors without using ducting. The UVs are controlled by pneumatic thermostats that regulate the heating to the user set point. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. 4.2.d Exhaust Systems As ventilation units bring outdoor air into the building, exhaust systems move indoor air into the atmosphere. A number of exhaust fans are located on the roof to remove air from classrooms, bathrooms and the multipurpose room. The exhaust fans were found to be in good condition. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. The following ECMs were identified as HVAC system improvements: 4.2.1 ECM-1A & B Replace Boilers Cast iron boilers have a useful life of approximately 30 years. The two existing HB Smith cast iron steam boilers at Lake Hiawatha Elementary School were installed in 1997 and are therefore still within their useful life. The heating system at Lake Hiawatha Elementary School is a combination of hydronic heating and steam radiant heating. According to the district HVAC specialist, the original portion of the school comprised of approximately 50% of the entire school area and uses steam unit ventilators to heat classrooms. The other 50% of the school uses heating hot water unit ventilators. The hot water is created from a heat exchanger that uses the steam from the boilers to heat water. The boilers are approximately 78% efficient according to the manufacturer name plate. Heat exchangers further decrease the efficiency of the heating system; the efficiency used for the hydronic system in the school was 62%. New high efficiency condensing hot water boilers have operating efficiencies around 92%. These new boilers have higher turndown ratios and outside air temperature resets which allow the boiler to better meet its load based on demand. The firing rate and water temperature are regulated by outside air temperature sensors and the heating load of the building. For this measure two alternatives were evaluated for savings and feasibility. The first option is ECM 1A which proposes changing all of the components in the steam system


to hot water including replacing the piping, valves, steam coil unit ventilators and installing high efficiency condensing hot water boilers. The second option (ECM 1B) proposes leaving the steam boilers to serve the steam system while installing (2) 1,500 MBH high efficiency condensing hot water boilers to service the hydronic system in the school with 100% redundancy. This will include removing the heat exchangers and replacing the heating hot water pump. The implementation cost and savings related to the two options of this ECM are presented in Appendix C and summarized below:

Lifetime Savings: 0 kWh 205,000 therms $235,000

This measure is not recommended due to the long payback period. However, parts of the steam system will eventually fail. When this happens consideration should be given to replace the steam system with a more efficient heating hot water system.

This measure is not recommended due to the long payback period. However consideration should be given to replace the existing heat exchanger system with hot water as portions of the steam system begin to fail.


4.2.2 ECM-2 Replace Window A/C units with a Central VRV System The elementary school is equipped with (29) window mounted AC units of varying capacity for classrooms and office spaces. Many of these units are below energy start efficiency, and the condition of some units ranges from fair to poor. It was noted during the field survey that some window mounted AC units change location between school years in order to accommodate students with allergies. Replacement of the existing window units with a Variable Refrigerant Volume (VRV) system will reduce energy and maintenance costs associated with the use of the window air conditioners. The VRV system will also be used to supplement heating costs for temperatures above 30F. The assumption of this calculation is that the operating hours will stay the same. The energy savings is a result of operating a higher efficiency system. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

* Does not qualify for Incentive from the New Jersey SmartStart Program. See section 5.0 for other incentive opportunities.

Expected Life: 20 years Lifetime Savings: 66,000 kWh 56,000 therms $74,000

This measure is not recommended due to the long payback period. However, this ECM might be worthwhile depending on how often each window a/c unit needs to be moved to accommodate a student with allergies. 4.3 Control Systems The boiler operation is controlled by an electronic boiler management system which controls the steam temperature and pressure as well as the actuating valves for the hot water (HW) heat exchangers. The boiler management system had controls in place to reset both steam pressure and HW temperature based on outdoor air temperature. The heating system includes classroom unit ventilators and fan coil units in hallways. The temperatures are controlled by pneumatic thermostats maintained by a 1.5 hp compressor. Thermostats are located in classrooms, hallways, multipurpose room and media center. The typical heating and cooling set points for the pneumatic section are 70F heating with no setback controls.


The following ECMs identified are improvements to the school’s HVAC control system: 4.3.1 ECM-3 Install a Timer to Enable Setback in the Pneumatic System The heating system at Lake Hiawatha Elementary School is programmed to maintain an indoor temperature of 72oF during all hours. Energy savings could be recognized with the implementation of setback controls to maintain a minimum temperature during unoccupied hours. The setback temperature considered in this calculation was 55oF. The annual natural gas usage for the facility was taking from the utility bills. According to the US Energy Information Agency (EIA), implementing a night setback system typically saves 15% of a facility’s annual heating cost. This savings is multiplied by the annual natural gas and converted to monetary savings using the unit cost of the fuel obtained from the utility analysis. Savings are seen from temperature scheduling for occupied and unoccupied hours. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

This measure is recommended. 4.4 Domestic Hot Water System Domestic hot water (DHW) for the school is provided by (1) Bradford White M280R6DS 80 gallon electric DHW heater located in a storage closet that is rated at 3.5 / 4.5 kW. The water is maintained at 120F and serves toilet rooms and sinks located throughout the school. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B.


The following ECMs identifies an improvement to the school’s Domestic Hot Water System: 4.4.1 ECM-4 Replace Electric Domestic Hot Water Heater with Condensing

Natural Gas Unit The school utilizes a 80 gallon Bradford White electric domestic hot water heater located in a storage closet. This ECM assesses replacing this domestic water heater with a more efficient tankless type domestic water heater sized to meet the domestic hot water requirements of the building. According to the U.S. Department of Energy, 2.5% of stored capacity is lost every hour during DHW heater standby. This value was applied to the total volume to determine annual standby losses. Proposed efficiency was based on a typical high efficiency natural gas condensing type hot water heater. The new water heater will require water and gas piping modifications, venting, and electrical connections. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

This measure is recommended. 4.5 Kitchen Equipment There is no kitchen at the Lake Hiawatha Elementary School. Food is prepared at either Parsippany High School or Brooklawn Middle School and delivered to the school each day. The food is then served to students and kept warm in electric powered warming stations. There are not ECMs associated with the kitchen equipment


4.6 Plumbing Systems Lake Hiawatha Elementary School has older style fixtures in the classroom and hallway restrooms. There are (11) water closets in the school, with a rating of 5.5 gallons per flush (GPF). There are (8) urinals in the school, with an average of 3.0 GPF and 30 faucets with an average flow rate of 3 gallons per minute (GPM). Each classroom has a sink, while only the kindergarten and first grade classrooms have restrooms. Per the number of occupants, it was estimated that each toilet and faucet is utilized approximately 4 times per day. The following ECM identifies an improvement to the school’s Domestic Hot Water System: 4.6.1 ECM-5 Water Conservation (Low Flow Fixtures) The water savings associated from replacing these fixtures with low-flow fixtures was calculated by taking the difference of the annual water usage for the proposed and base case. The basis of this calculation is the number of times each fixture is used, gallons per use, and number of fixtures. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

This measure is not recommended due to the long payback period. 4.7 Lighting/Electrical Systems The majority of the lighting in Lake Hiawatha Elementary School is comprised of T-8 fluorescent tube fixtures with electronic ballasts and incandescent lamps. The lighting in the Multi-Purpose room has been recently upgraded to fluorescent T5 fixtures with electronic ballasts. The bathrooms in the kindergarten and first grade classrooms have single bulb incandescent fixtures. The building’s exterior lighting includes several high pressure sodium wall pack units. The pole lights in the parking lot and playground are


property of Jersey Central Power and Light, and are billed monthly. A comprehensive lighting survey can be found in Appendix B. Lake Hiawatha Elementary School utilizes 162 computers throughout the building in classrooms, offices, media centers and computer labs. All computers have flat screen LCD monitors. The following ECMs identified are improvements to Lake Hiawatha Elementary School’s lighting and electrical system: 4.7.1 ECM-6 Lighting Replacement / Upgrades The school uses T-8 fixtures with electronic ballasts in classrooms, offices, and hallway spaces. Single bulb incandescent fixtures were used in closets, storage rooms, and small bathrooms. Each switch and circuit was identified, and an inventory of fixtures, controls and locations was established during the field survey (Appendix B). There is an opportunity to reduce consumption by upgrading the incandescent fixtures to compact fluorescent lamps. This would involve a replacement of the bulb, The exterior lighting on the building walls is proposed to be changed from high pressure sodium and metal halide to LED, which has a longer life and consumes much less energy. This will involve a full fixture replacement. Energy savings for this measure were calculated by applying the existing and proposed fixture wattages to estimated times of operation. These calculations are based upon 1 to 1 replacements with the fixtures. They do not take into account lumen output and square footage. A more comprehensive study may be performed to determine correct lighting levels. Supporting calculations, including assumptions for lighting hours and annual energy usage for each fixture, are provided in Appendix C. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

This measure is not recommended in lieu of ECM-8.


4.7.2 ECM-7 Install Lighting Controls (Occupancy Sensors) Currently the light fixtures within classrooms, multipurpose room and the media center are controlled via switches regardless of occupancy. Therefore, installing an occupancy sensor in these spaces to turn off lights when the areas are unoccupied was assessed. This measure recommends installing occupancy sensors for the current lighting system. Using a process similar to that utilized in section 4.6.1, the energy savings for this measure was calculated by applying the known fixture wattages in the space to the estimated existing and proposed times of operation for each fixture. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

This measure is not recommended in lieu of ECM-8. 4.7.3 ECM-8 Lighting Replacements with Controls (Occupancy Sensors) This measure is a combination of ECM-6 and ECM-7; recommending replace/upgrade the current lighting fixtures to more efficient ones and installing occupancy sensors on the new lights. Interactive effects of the higher efficiency lights and occupancy sensors lead the energy and cost savings for this measure to not be cumulative or equivalent to the sum of replacing the lighting fixtures alone and installing occupancy sensors without the lighting upgrade. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

recommended measures identified in a previous energy assessment, such as this energy audit. The incentive is reimbursed to the school upon successful replacement and payment of the equipment. This school is eligible to receive funding from the Direct Install Program because the electrical demand is less than the maximum peak electrical demand of 150 kW in the last 12 month period. Refer to appendix D for more information on this program. 5.1.3 New Jersey Pay For Performance Program (P4P) The facility will be eligible for incentives from the New Jersey Office of Clean Energy. The most significant incentives are available from the New Jersey Pay for Performance (P4P) Program. The P4P program is designed for qualified energy conservation projects applied to facilities whose demand in any of the preceding 12 months exceeds 100 kW. This average minimum has been waived for buildings owned by local governments or municipalities and non-profit organizations, however. Facilities that meet this criterion must also achieve a minimum performance target of 15% energy reduction by using the EPA Portfolio Manager benchmarking tool before and after implementation of the measure(s). If the participant is a municipal electric company customer, and a customer of a regulated gas New Jersey Utility, only gas measures will be eligible under the Program. Available incentives are as follows: Incentive #1: Energy Reduction Plan – This incentive is designed to offset the cost of services associated with the development of the Energy Reduction Plan (ERP).

Incentive Amount: $0.10/SF Minimum incentive: $5,000 Maximum Incentive: $50,000 or 50% of Facility annual energy cost

The standard incentive pays $0.10 per square foot, up to a maximum of $50,000, not to exceed 50% of facility annual energy cost, paid after approval of application. For building audits funded by the New Jersey Board of Public Utilities, which receive an initial 75% incentive toward performance of the energy audit, facilities are only eligible for an additional $0.05 per square foot, up to a maximum of $25,000, rather than the standard incentive noted above. Incentive #2: Installation of Recommended Measures – This incentive is based on projected energy savings as determined in Incentive #1 (Minimum 15% savings must be achieved), and is paid upon successful installation of recommended measures. Electric

Base incentive based on 15% savings: $0.09/ per projected kWh saved. For each % over 15% add: $0.005 per projected kWh saved. Maximum incentive: $0.11/ kWh per projected kWh saved

Gas Base incentive based on 15% savings: $0.90/ per projected Therm saved.


For each % over 15% add: $0.05 per projected Therm saved. Maximum incentive: $1.25 per projected Therm saved

Incentive cap: 25% of total project cost Incentive #3: Post-Construction Benchmarking Report – This incentive is paid after acceptance of a report proving energy savings over one year utilizing the Environmental Protection Agency (EPA) Portfolio Manager benchmarking tool. Electric

Base incentive based on 15% savings: $0.09/ per projected kWh saved. For each % over 15% add: $0.005 per projected kWh saved. Maximum incentive: $0.11/ kWh per projected kWh saved

Gas

Base incentive based on 15% savings: $0.90/ per projected Therm saved. For each % over 15% add: $0.05 per projected Therm saved. Maximum incentive: $1.25 per projected Therm saved

Combining incentives #2 and #3 will provide a total of $0.18/ kWh and $1.8/therm not to exceed 50% of total project cost. Additional incentives for #2 and #3 are increased by $0.005/kWh and $0.05/therm for each percentage increase above the 15% minimum target to 20%, calculated with the EPA Portfolio Manager benchmarking tool, not to exceed 50% of total project cost. Total P4P incentives are summarized below:

Incentives $ Electric Gas Total

Incentive #1 $0 $0 $5,000 Incentive #2 $4,866 $4,325 $9,191

Incentive #3 $4,866 $4,325 $9,191

Total $9,731 $8,650 $23,381

For the purpose of demonstrating the eligibility of the ECM’s to meet the minimum savings requirement of 15% for the Pay for Performance Program, all recommended ECM’s have been included in the incentive calculations resulting in a 15.1% energy savings. Based on this savings, the school would be eligible for the Pay for Performance Program. Refer to appendix D for more information on this program. 5.1.4 Energy Savings Improvement Plan (ESIP) The Energy Savings Improvement Program (ESIP) allows government agencies to make energy related improvements to their facilities and pay for the costs using the value of energy savings that result from the improvements. Under the recently enacted Chapter 4


of the Laws of 2009 (the law), the ESIP provides all government agencies in New Jersey with a flexible tool to improve and reduce energy usage with minimal expenditure of new financial resources. ESIP allows local units to use “energy savings obligations” to pay for the capital costs of energy improvements to their facilities. This can be done over a maximum term of 15 years. Energy savings obligations are not considered “new general obligation debt” of a local unit and do not count against debt limits or require voter approval. They may be issued as refunding bonds or leases. Savings generated from the installation of energy conservation measures pay the principal of and interest on the bonds; for that reason, the debt service created by the ESOs is not paid from the debt service fund, but is paid from the general fund. For local governments interested in pursuing an ESIP, the first step is to perform an energy audit. Pursuing a Local Government Energy Audit through New Jersey's Clean Energy Program is a valuable first step to the ESIP approach. The “Local Finance Notice” outlines how local governments can develop and implement an ESIP for their facilities. The ESIP can be prepared internally if the entity has qualified staff. If not, the ESIP must be implemented by an independent contractor and not by the energy savings company producing the Energy Reduction Plan. The ESIP approach may not be appropriate for all energy conservation and energy efficiency improvements. Local units should carefully consider all alternatives to develop an approach that best meets their needs. Refer to appendix D for more information on this program.

This measure is not recommended due to the long payback time. It is suggested, however, that the school continue to monitor the SREC credits and evaluate the PV installation again should the SREC credit values increase. 6.1.2 Solar Thermal Hot Water Generation Active solar thermal systems use solar collectors to gather the sun’s energy to heat water, another fluid, or air. An absorber in the collector converts the sun’s energy into heat. The heat is then transferred by circulating water, antifreeze, or sometimes air to another location for immediate use or storage for later utilization. Applications for active solar thermal energy include providing hot water, heating swimming pools, space heating, and preheating air in residential and commercial buildings. A standard solar hot water system is typically composed of solar collectors, heat storage vessel, piping, circulators, and controls. Systems are typically integrated to work alongside a conventional heating system that provides heat when solar resources are not sufficient. The solar collectors are usually placed on the roof of the building, oriented south, and tilted around the site’s latitude, to maximize the amount of radiation collected on a yearly basis. Several options exist for using active solar thermal systems for space heating. The most common method involves using glazed collectors to heat a liquid held in a storage tank (similar to an active solar hot water system). The most practical system would transfer the heat from the panels to thermal storage tanks and transfer solar produced thermal energy to use for domestic hot water production. DHW is presently produced by gas-fired water heaters and, therefore, this measure would offer natural gas utility savings. 6.2 Demand Response Curtailment Presently, Electricity is delivered by JCP&L, which receives the electricity from regional power grid RFC. PMJ is the regional transmission organization (RTO) that coordinates the movement of wholesale electricity in all or parts of 13 states and the District of Columbia including the State of New Jersey. Utility Curtailment is an agreement with the utility provider’s regional transmission organization and an approved Curtailment Service Provider (CSP) to shed electrical load by either turning major equipment off or energizing all or part of a facility utilizing an


emergency generator; therefore, reducing the electrical demand on the utility grid. This program is to benefit the utility company during high demand periods and utility provider offers incentives to the CSP to participate in this program. Enrolling in the program will require program participants to drop electrical load or turn on emergency generators during high electrical demand conditions or during emergencies. Part of the program also will require that program participants reduce their required load or run emergency generators with notice to test the system. A pre-approved CSP will require a minimum of 100 kW of load reduction to participate in any curtailment program. From November 2011 through October 2012 the facility had a peak electricity demand of 108.2 kW and a minimum of 97.3 kW. The monthly average over the observed 12 month period was 100.3 kW. This building currently has a 180 kW diesel generator on site. The district currently has a contract with Ener-Noc for a few of their school buildings. As of January 2013 their contract has been renewed with Ener-Noc. It is not recommended that they adjust their current contract at this time.
