1 2018 NYStretch- Energy Kickoff Meeting June 8, 2017 Albany, NY 2017, New Buildings Institute Agenda Welcome and Policy Context Priscilla Richards, NYSERDA NYC Policy Context John Lee, NYC Mayor s Office of Sustainability Overview of project team, process and timetables Priscilla Richards and Jim Edelson, NBI Overview of technical approach Priscilla Richards, Jim Edelson and Kevin Carbonnier, NBI Multifamily Opportunities for Considerations Discussion and feedback on Structure and Approach All Lunch break (45 minutes) Commercial, Multifamily and Residential modeling approaches and considerations Bing Liu and Maria Karpman, Karpman Consulting Code measures for consideration Jim Edelson and Mark Lyles, New Buildings Institute Discussion and formation of workgroups All Update on 2016 NYStretch Energy Status and Implementation Plans Priscilla Richards Wrap-Up and next steps 1

2 Welcome and Policy Context Priscilla Richards - NYSERDA Stretch Energy Code Concept 4 Results in more energy savings than a base energy code Mandatory or voluntary mechanisms Adopted by cities Used for public buildings Tax or other incentive programs Signals where future codes are going Can work in tandem with utility programs - regulatory, timing, and savings 2

3 Reforming the Energy Vision (REV) REV is a comprehensive strategy to build a clean, resilient, and affordable energy system for all New Yorkers, with a focus on three core approaches to drive transformation 5 Regulatory Reform (PSC) reshaping NY s electric industry and utility business practice to encourage the cleanest, most advanced, and efficient power system operation Market Activation (NYSERDA) addressing market barriers and gaps; redesigning NY programs to accelerate clean energy market growth and unlock private clean energy investment Leading by Example (NYPA) - deploying innovative energy solutions across State-owned buildings, university campuses, and State vehicle fleets 6 ny.gov/rev4ny 3

4 NY Stretch Energy Objective 7 NY Stretch Energy Objective Provide readily-adoptable code language for local governments in NY that will deliver energy efficiency performance significantly above anticipated 2019 NYECC code What is NYStretch-Energy? Overlay code, or alternative compliance path, for local adoption (as MRLS) + More rigorous than base energy code + Results in buildings that achieve greater energy savings and reduced GHG emissions + Anticipates successor code advancements, culminating in a statewide Net Zero Energy code by 2028/30 8 4

5 NY Stretch in Context 9 Part of NYSERDA s suite of code-related activities: Online and classroom trainings Municipal support/plan review Code Commentaries Benefits of a Stretch Code Lower building operating costs/increased energy savings Increased occupant comfort Improved resiliency (with regard to power disruptions) Signal transition to performance-based codes Allows design flexibility Stimulates R&D and commercialization of products/systems to improve energy efficiency performance Provides consistency while leveraging developed above-code infrastructure Alignment with utility programs 10 5

12 2018 NYStretch Overview Code Application Prescriptive (commercial), ERI, and modeling compliance Base codes IECC, ASHRAE Measure development Survey advancing codes ( , CA T , WA state) Cooperate with Zero Cities and Washington State code development efforts Examine range compliance options (Appendix g; ERI/HERS scores) Measures being considered areas of opportunity Envelope - Modeling Lighting - Renewables HVAC - Load Shape and Grid Impacts Water Heating - Resiliency, EVs, Fuels.. Modeling of NYStretch Savings Full modeling of residential and commercial measures Supported by PNNL for commercial Supported by Earth Advantage for residential Preliminary and final modeling rounds for savings determination Across three NY Climate Zones and five common commercial building types and two different sized residential buildings (Discusssion of modeling after lunch) 12

13 EUI Targets and NYStretch Helps provide comparisons among codes and policy objectives Generally aiming for weighted-average energy savings of 20% beyond / 2015 IECC Targets are computed as weighted-averages of 3 NY Climate Zones Can later be correlated to Performance Cost Index Targets framework in ASHRAE 90.1 Appendix g.

22 Commercial Modeling Methodology Bing to present Recommendations and Review Manual Funded by NYSERDA, implemented by Karpman Consulting Policy Recommendations report is completed, development of the Review Manual is under way Incorporate input of members of ASHRAE Standard 90.1 committee, chair of ASHRAE TC 4.7 (Energy Calculations), chief of PNNL s Commercial Energy Code Development team, Director of Energy Code Compliance NYC Department of Buildings, technical director of USGBC Energy/HVAC team, and other local and national stakeholders 22

23 Policy Recommendations Minimize the number of compliance options to simplify enforcement, making 90.1 Appendix G the only performance path Establish qualification requirements for modelers and reviewers Engage third part reviewers if there are no in house staff with the necessary qualifications Adopt a detailed, structured submittal review template, aligned with the requirements of other compliance modeling applications common in New York Develop and document the review process; incorporate some QC checks into the submittal review template for automation; get input on the QC checks from vendors of the software tools popular in NY Provide trainings to the code officials and third party reviewers on the use of the submittal template and review process.
