4 SECTION 1 PROJECT OVERVIEW The New York State Energy Research and Development Authority (NYSERDA) administers the New Construction Program (NCP) that assists eligible building owners and leaseholders in improving the energy efficiency of new or substantially renovated buildings. Funding is available through this program to conduct technical assessments of energy efficiency measures in building or space designs, and to offset a portion of the incremental capital costs to purchase and install the qualified measures. Projects may also qualify for green building services, building commissioning services (Cx), LEED incentives, and Design Team incentives. General information about the project is summarized in Table 1-1.

5 Table 1 2: Project Description Binghamton University is proposing an Energy R&D Building to help integrate its efforts between cutting edge research in the physical sciences and its strengths in engineering. The center will enable industry partners to develop new energy technologies while further broadening their regional workforce. The project includes state of the art laboratory spaces with room for facilitating side by side collaborations between faculty and industry professionals. This inter disciplinary research building will contain offices, research labs, support spaces, common and collaboration spaces and upper division instructional spaces. The project is applying for LEED certification with goals of Platinum and 19 EAc1 points. The proposed design includes efficient VAV air distribution with heat recovery, low flow hoods and lab exhaust with temperature setback controls. The lighting design includes a majority of LED fixtures, daylight harvesting and occupancy sensors. The HVAC design will include high efficiency hot water condensing boilers, variable speed dual compressor magnetic bearing water cooled chillers, variable speed pumps and supply fans. An improved envelope and high efficiency service hot water system will be modeled but not evaluated as an Energy Conservation Measure (ECM). Water cooled process equipment and low flow service hot water fixtures will be installed in laboratory spaces but not evaluated as ECMs since equipment/fixture choices will be made later. Green energy including photovoltaic panels, fuel cells and microturbines will be considered by the design team and owners but not evaluated as part of the TA analysis. The Whole Building analysis for this project used equest energy modeling software to simulate projected energy use of the proposed design versus an ASHRAE baseline building. A view of the building geometry as modeled appears below. NCP11870 Energy RD Building 5

8 NYSERDA recommends commissioning for all buildings, but requires it for projects receiving a capital cost incentive greater than $100,000. For buildings that are commissioned, the capital cost incentive is increased by 10% to offset a portion of the Cx costs. Applicants may have commissioning services provided by a consultant of their choice, including a NCP Technical Assistance provider. Applicants must make their own contracting arrangements for commissioning. NYSERDA requires the Commissioning Authority and Applicant to complete and submit a Building Commissioning Certification Form, provided as a separate document by your Outreach Project Consultant, once commissioning has been completed in order to release the full incentive award. SECTION 4 ANALYSIS METHODOLOGY AND ENERGY SAVINGS The Performance Rating Method (PRM) of ASHRAE Standard Appendix G and the NCP Simulation Guidelines in effect when the Task Work Order was approved by NYSERDA were used to analyze the project s energy performance. Following the PRM, a whole building energy simulation was performed to determine improvement of the proposed design relative to a baseline building that minimally complies with Appendix G. The baseline and proposed designs were modeled using a computer simulation program that requires the input of key characteristics for the building shell, mechanical and electrical systems, along with operating strategies and schedules provided by the owner and design team to estimate potential energy savings for a wide range of design alternatives and energy efficiency strategies. The analysis captures interactions between different building systems, and includes simulating projected annual energy consumption at hourly time intervals using typical or long-term average weather data for the location. Additional simulations are performed for each ECM to evaluate its contribution toward the project s energy and demand savings. This analysis is used to help guide the project s design and to determine the project incentives. Full details on the components included in the baseline and proposed design simulations are included in the companion spreadsheets developed for the project. They have been submitted to NYSERDA and are available upon request. Table 4-1 is based on the results of the modeling analysis and shows energy savings of the proposed design, including all of the ECMs included in this report, relative to the baseline condition. The consumption is broken down by the key end use categories such as interior lighting, space heating and cooling, fans and motors. NCP11870 Energy RD Building 8

10 Neither the proposed building performance nor the baseline building performance are predictions of actual energy consumption or operating costs for the proposed design after construction. Actual energy consumption may 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. Energy savings from the measures evaluated in this study will, if implemented, provide additional economic and societal benefits due to reduced emissions from electric power generating plants. These benefits include decreased incidents of respiratory ailments, asthma and allergies, as well as the reduction of negative impacts on property and the environment. Table 4-2 lists selected emission reductions for this project. Table 4 2: Emission Reduction ECM All ECM's Reduction in Nox (lbs.)

11 SECTION 5 NYSERDA INCENTIVES The project incentives were calculated using a whole building energy simulation following ASHRAE Standard Appendix G and the NCP Simulation Guidelines. Table 3-1 shows financial incentives available from NYSERDA for the project based on this analysis. NYSERDA will issue an incentive check to the Owner after construction is completed and installation of the design components contributing to the energy and demand savings are inspected to verify program compliance. A second check may be issued by NYSERDA for the LEED related incentives after certification is obtained. Table 5-2 shows annual energy and peak demand savings for each of the Energy Conservation Measures (ECMs) that qualify for incentives, and the effective payback of the ECMs taking into account the recommended incentive. Each ECM includes one or more design components that were analyzed as a system to evaluate their combined impact on the project s energy performance. The Electric Savings and Fossil Fuel Savings columns of the table represent estimated energy cost savings for each evaluated ECM. These cost savings were developed using representative utility rates and the modeling methodology outlined in Section 5. The Incremental Cost column of the table represents the estimated increase in capital cost investment of each evaluated ECM. These costs were developed based on project data, market averages, NYSERDA program information, and past experience of the TA. These costs are used to estimate the simple payback and cost effectiveness of each ECM. The NYSERDA Incentive column of the table represents the contribution of each ECM toward the total Whole Building Design incentive. The design components included in each ECM are itemized in Section 4 of the report. If any of the listed design components are not installed or do not meet the stated minimum performance requirements, the overall Whole Building Incentive offer will be reduced to reflect the quantity or efficiency of the installed components as deemed appropriate by NYSERDA.
