Background ’ Ithaca has a strong history of sustainability efforts Engaged community organizations & residents City and Town Comprehensive Plans endorse sustainability, equity, and climate action Aggressive GHG reduction goals ’ Local climate action is now more important than ever IPCC and Climate Assessment reports convey dire need for action Local governments being looked to for leadership as Federal government dismantles existing climate action 4
Background ’ Reducing energy use in GHG Emissions From Buildings as Share of Total Community Emissions buildings is key to meeting GHG reduction goals City of Ithaca ’ The Green Building Policy focuses on new 75% construction, the “easy” part ’ Existing buildings have Town of Ithaca begun to be addressed, but more work is needed 50% 5
Background These groups guided the creation of the GBP: ’ Consultants STREAM Collaborative Taitem Engineering Randall + West Planners ’ Steering Committee & Working Group City of Ithaca and Town of Ithaca elected officials and senior staff members ’ Advisory Committee 13 community stakeholders from local organizations representing: economic development, design, real estate, energy, planning, social equity, and other fields ’ Stakeholder Outreach To municipal boards, organizations, and general public Over 200 comments influenced GBP report 6
Background A successful green building policy should be F.A.I.R. F lexible 1. o Multiple paths to meet compliance 2. A ffordable o Reduced, same or minimally more than conventional construction costs 3. I mpactful o Reduced energy use and GHG reductions 4. R eachable o Achievable, both for developers and municipal staff 7
Background ’ Green Building Policy report was approved by Common Council and Town Board in May 2018 ’ Policy recommendations from report were starting point for Ithaca Energy Code Supplement ’ IECS draft Easy-to-understand document Contains “all” content that will be in final Energy Code Supplement Formatted for ease of discussion and editing ’ Goal is one unified Code used in both Town and City 8
Background ’ Estimated Timeline August 2019 : Draft Energy Code Supplement discussed, considered for public circulation by Town and City August/September : Public outreach (if approved) October/November : Finish codification Nov-Dec 2019/Jan 2020 : Council and Town Board consider adoption of final legislation 9
Ithaca Energy Code Supplement 10
Overview Requirements ’ New buildings must meet requirements to reduce GHG emissions by 40% ’ Must also comply with all NYS codes Future Code Cycles ’ Requirements become more stringent in 2025 and 2030 ’ 2030 code will require net-zero construction free of fossil fuels Incentives ’ Existing and proposed incentives would facilitate compliance and promote early adoption of best practices ’ Discussion is ongoing 11
Requirements Two compliance options 1. Easy Path -OR- 2. Whole Building Path ’ Point system ’ Allows more flexibility in building design ’ Achieve minimum of 6 points to pass ’ Must comply with a high- performance building ’ Easy to use standard OR use energy ’ Emphasis on affordability and modeling electrification Certification is not necessary 12
Requirements Applicability ’ All new construction Residential, commercial, industrial, etc. ’ Major renovations At least 75% of the square footage in an existing building is being renovated At least two of the following major energy components are being substantially renovated: heating, lighting, and envelope ’ Additions Single family and duplex: additions > 500 sq ft All other buildings: additions > 1,000 sq ft ’ Historic Buildings are exempt (under discussion) 13
Requirements Future Code Cycles ’ 2020: Base requirements as described previously; 40% reduction in GHG emissions Proposed to go into effect six months following adoption ’ 2025: Requirements increase; 80% GHG reduction ’ 2030: Requires net-zero carbon buildings and no fossil fuels 14
Incentives Incentive package is proposed Incentive package could include: for projects that: ’ Property Tax abatements ’ Meet requirements of the next code cycle Green Building Tax Exemption ’ Are fossil fuel free ’ Additional square footage Height, stories, lot coverage, ’ Meet walkability criteria parking requirements ’ Commit to share energy use ’ Building permit relief data E.g. streamline; cost reduction or rebate Other incentives are already ’ Recognition program available for basic compliance, including NYSERDA and PACE financing. 15
Anticipated Results 40% reduction in GHG ’ emissions at building level Baseline: NYS Energy Code for new construction AND local building practices Lower or similar construction ’ costs (using Easy Path) Increasing emissions from ’ building sector growth would level off Policies to address existing buildings will be needed to meet GHG reduction goals. 16
The Easy Path 17
Easy Path Overview Six points are needed to comply. Details on each point are provided on the following slides. Efficient Electrification EE1 - Heat pumps for space heating 2 - 5 points EE2 - Heat pumps for domestic hot water heating 1 point (Residential, hotel only) EE3 - Other electrification 1 point (Residential, food svc only) Affordability Improvements AI1 - Smaller building/room size 1 - 2 points (Residential, hotel only) AI2 - Heating systems in heated space 1 point AI3 - Efficient building shape 1 point AI4 - Right-lighting 1 point (Commercial only) AI5 - Modest window-to-wall ratio 1 point Renewable Energy RE1 - Renewable energy (non-biomass) system 1 - 3 points RE2 - Biomass system for space heating 3 - 5 points Other Points OP1 - Development Density 1 point OP2 - Walkability 1 point OP3 - Adaptive reuse 1 point OP4 - Meet NY Stretch Energy Code 2 points OP5 - Custom energy Improvement (no fossil fuels) 1 - 2 points 18

Efficient Electrification EE1 Heat pumps for space heating Electric heat pumps are more energy efficient than fossil fuel based space heating equipment. Requirement: Heat pumps for space heating; no fossil fuels used for HVAC system. Possible Points: 2-5 2 points (Commercial) or 3 points (Residential) for air source heat pumps. 3 points (Commercial) or 5 points (Residential) for ground source heat pumps. 20
Efficient Electrification EE2 Heat pumps for water heating Electric heat pumps are more energy efficient than fossil fuel based water heating equipment. Requirement: Water heating systems that use heat pumps. Possible Points: 1 Residential only. 21
Efficient Electrification EE3 Other electrification (continued next slide) Electric stoves and heat pumps clothes dryers produce fewer GHG emissions than fossil fuel based equipment. Requirement: Electric stoves AND ventless heat pump clothes dryers. Prerequisite: no fossil fuels in the building. Possible Points: 1 Residential only. 22
Efficient Electrification EE3 Other electrification (continued) Electric cooking equipment produces fewer GHG emissions than fossil fuel based equipment. Requirement: Only electric cooking equipment in restaurants and other food service buildings that have commercial kitchen hoods. Prerequisite: no fossil fuels in the building. Possible Points: 3 Restaurants and food service only. 23
Affordability Improvements AI1 Smaller building/room size Smaller buildings use less energy and cost less. The impact on energy use is almost linear, due to energy Example: Single Family Homes* uses that scale with size, like Floor area (sq. ft.) per Number of Bedrooms heating, cooling, lighting, etc. 1 2 3 4 1,000 1,600 2,200 2,800 Requirement: Building size (sq. ft.) is smaller than the thresholds identified in the LEED/EnergyStar's reference table for conditioned floor tables. area of reference home, by number of bedrooms. *Different tables are used for multifamily buildings and hotels. Possible Points: 1 - 2 1 point for 15% smaller than reference size. 2 points for 30% smaller. Residential and Hotels only. 24
