What is Needed to Get to Net-Zero Emissions for New Buildings By 2025 at the latest: • All new buildings are constructed to net-zero GHG emissions standards by performing at or better than a greenhouse gas intensity limit of 1kg/m 2 /year. • All new buildings have at least 10% of their electricity produced on site by solar PV systems. • Efficient fixtures and irrigation achieve a 30% reduction in water use compared to typical base building of the same type, floor area, and occupancy. What is also Needed to Get to Net-Zero Emissions for New Part 3 Buildings To decrease the urban heat island effect, better manage stormwater, and promote biodiversity, all new Part 3 buildings have at least partial green roof coverage, according to Table C-1: Available roof space is defined as the total roof area minus areas dedicated to renewable energy infrastructure. However, these two roof coverings are not mutually exclusive; renewable energy infrastructure can be installed overtop green roofing, provided the plant species are shade tolerant.

What is Needed to Get to Net-Zero Emissions for Existing Buildings • By 2040, 80% of buildings built before 2022 are retrofit to achieve deep energy efficiency improvements achieving a minimum of 50%

Coverage of Available Roof Space (Size of Green Roof)

Gross Floor Area (Size of Building) 2,000–4,999 m² 5,000–9,999 m² 10,000–14,999 m² 15,000–19,999 m² 20,000 m² or greater

energy use reduction. The thermal energy supply in these buildings will be met through electric systems. • By 2050, 100% of buildings built before 2022 are retrofit to achieve deep energy efficiency improvements achieving a minimum of 50% energy use reduction. The thermal energy supply in these buildings will be met through electric systems.
