Transcription

1 Toronto s Regulatory Framework Building Integrated PV Symposium 2014 New Visions for Solar in the Built Environment Jane Welsh Acting Project Manager, Zoning Bylaw and Environmental Planning, City of Toronto

2 Our city is growing

3 Density 2031 more people; same land - how will we cope?

4 Development bigger buildings; same infrastructure how do we build more with less?

5 ELECTRICITY CONSTRAINTS Capacity of transformer stations serving Downtown Toronto Need for: - Conservation - Distributed Generation (including renewables)

6 Our weather is changing

7 Amount in mm CHANGES IN PRECIPITATION & TEMPERATURE Extreme Daily Rainfall (>25mm/day) Fewer Pptn. Storms >25 mm in Winter Same Number of Storms in Summer BUT these = Much More Intense Storms!! Extreme Temperature: Number of Days >30 C Increase in extreme maximum daily temperature Increase in number of heat waves 180 Pearson Airport: Extreme DAILY Rainfall Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Month

8 Our approach is shifting Regent Park

9 CONSULTATION RESEARCH EDUCATION ADOPTION

10 Regulatory Framework Toronto Green Standard Policies and Guidelines Tall Building Guidelines Provincial Policy Statement Municipal Official Plan Green Roof Bylaw Avenues & Mid-Rise Buildings Study Regulations Ontario Building Code Zoning Bylaw

11 PROVINCIAL POLICY STATEMENT Planning authorities should promote renewable energy supply and renewable energy systems and alternative energy systems. Promote design and orientation which maximizes opportunities for the use of renewable energy systems Planning Act Green Energy Act

12 OFFICIAL PLAN POLICIES 3.4.1(c) Reducing reliance on carbon based fuels (d) Innovative energy producing options will be supported by establishing solar power installations (c) Secure sustainable design features in Tier 1 of TGS including building orientation to take advantage of passive solar heating.

13 ZONING BYLAW Zoning controls Land Use, density, height and setbacks: Rules set for height and density Zoning Bylaw amendment required to change Public process requires consultation with neighbours Renewable Energy Bylaw Permits energy production and distribution using renewable energy devices and co-generation devices on every property, subject to the zone regulations Under Green Energy Act installation of renewables on rooftops no longer subject to planning regulations Zoning Bylaw

14 TORONTO GREEN STANDARD Applies to New Development 1. Low-rise residential 4 stories, 5 units 2. Mid-rise to High-rise 4 stories And all Low-rise ICI

15 TIER 1: MINIMUM REQUIRED STANDARD + 15% Energy Efficiency above OBC Bird-Friendly Stormwater Retention & Quality Green Roofs Tree Planting Cool Paving Pedestrian Infrastructure Cycling Infrastructure

16 5% renewable energy TIER 2 PACKAGE +25% Energy Efficiency above OBC Green Walls +30% Water Efficiency 75% construction waste diversion Bird-Friendly Building Commissioning 10mmStormwater Retention BETTER Building Materials +75% UHI treatment at-grade Building Reuse Regional Materials Recycled Content Lighting/Shielding Natural Restoration 1.2/unit Enhanced Bike Parking; Bike Share

17 ENERGY EFFICIENCY Minimize energy demand through efficient building design and encourage renewable energy TIER T1 all uses: Design the building(s) to achieve at least 15% energy efficiency improvement over the current Ontario Building Code (OBC) T2 all uses: Design and construct the building(s) to achieve at least 25% energy efficiency improvement over the current Ontario Building Code (OBC) Updated Energy Report Terms of Reference NEW Energy Modeling Guidelines

18 TIER 2 SUMMARY: DEVELOPMENT CHARGE REFUND 20% Tier 2 5 CORE categories & targets: UHI Reduction Energy Efficiency Commissioning, Water Efficiency and Light Pollution Reduction PLUS 3 optional targets selected by the applicant: Added 10 new optional targets including renewable energy 1% renewable energy 775 King St West

19 RENEWABLE ENERGY On-Site Renewable Energy for City-Owned Buildings and all ABCCs All new City buildings must install renewable energy technology/ies that produce a minimum of 5% of the building s modelled energy use Projects must be technically possible and financially feasible Solar PV and geothermal are typically the most viable technologies

20 BIRD FRIENDLY DESIGN Reduce bird collisions and mortality from buildings TIER T1 all uses: Treat 85% of all exterior glazing within the first 12m using a combination of strategies: Low reflectance, opaque materials Visual markers 100mm by 100mm such as frit, BIPV

21 ENHANCE ECOLOGY AND THE NATURAL ENVIRONMENT: Urban Forest, Natural Heritage, Bird-Friendly, Light Pollution (VISUALS TO SUPPORT )

22 GREEN ROOF BYLAW Coverage requirement based on building size 2,000 4,999 m 2 20% 5,000-9,999 m 2 30% 10,000-14,999 m 2 40% 15,000-19,999 m 2 50% 20,000 m 2 or greater 60% Total Roof Area excludes areas devoted to renewable energy

23 SUN SHADOW STUDIES Official Plan policy: new development to limit impact on neighbouring streets, parks, open spaces and properties by...limiting shadowing... Sun shadow studies: Model Impact of shadows on streets, parks, open spaces Applies to applications for ZBLA or complex SPA over 20 m (6 storeys) Less than 20m where additional height applied for near shadow sensitive areas (parks, schools, cemeteries)

24 TALL BUILDING GUIDELINES Uses 45 degree angular plane to control transitions between tall buildings to lower scale areas

25 MID-RISE GUIDELINES Mid-rise buildings transitions to neighbourhood 5 hours sunlight spring to fall
