5 Global Context Dec COP 21 Conference in Paris (192 Nations) International Panel on Climate Change (IPCC) has determined that we risk severe, pervasive and irreversible impacts from climate change, and need substantial greenhouse gas emissions reductions (of 40-70% or more) by mid-century. Community agreed to hold the increase in the global average temp to well below 2 degrees Celsius above pre-industrial levels Pursue efforts to limit temperature increase to 1.5 degrees Celsius above pre-industrial levels During the meeting, there was agreement to commit to the highest possible ambitions to achieve this goal. 5

6 Background 1. California Building Code Cycles Every three years the California Building Codes are updated Next code cycle is targeted for enforcement on 1/1/ History of Palo Alto Energy Ordinances Increased stringency over state requirements for the last three code cycles (first established in 2008) 3. Green Building Advisory Group (GBAG) Regular meetings identifying appropriate direction Day-long retreats in August of 2014 and October of 2015 Six technical meetings in 2015/ 2016 with the Green Building Technical Advisory Committee to develop the specified ordinance Criteria 6

14 Energy Reach Code Ordinance Improvements New Energy Reach Code Increased energy efficiency above state requirements Solar PV is allowed to be used as a credit towards energy efficiency Percent requirements is dependent on the presence or absence of solar photovoltaic power (PV) Cost-effectiveness study performed to ensure requirements are financially responsible (CEC requirements) 15

15 Single Family Residential BASE CODE PALO ALTO REACH CODE OPTIONS All Projects in CA PATH A (No PV) PATH B (With PV) Up to 20% can be PV 10% 20% Reach Code Meeting Minimum Base Code Base Code = Energy Efficiency = Renewables (PV) 16

16 Multi Family Residential BASE CODE PALO ALTO REACH CODE OPTIONS All Projects in CA PATH A (No PV) PATH B (With PV) Up to 12% can be PV 10% 12% Reach Code Meeting Minimum Base Code Base Code = Energy Efficiency = Renewables (PV) 17

17 Commercial BASE CODE PALO ALTO REACH CODE OPTIONS All Projects in CA PATH A (No PV) PATH B (With PV) No PV can contribute to Base Code 10% Min 5kW PV System Reach Code Meeting Minimum Base Code Base Code = Energy Efficiency = Renewables (PV) 18

18 Tons CO2e Emissions Annual Greenhouse Gas Savings 1,400 1,200 1, All Building Types T24 Part 6 Palo Alto Reach Code 6% Savings, or 71 tons/year *Based on 2015 Building Permit Data 19

19 Residential Energy Reach Code Ordinance Improvements New Single-Family Residential New Multi-family Residential No PV 10% More efficient than Base Code ( a.1) 10% More efficient than Base Code ( b.1) With PV 20% More efficient than Base Code¹ ( a.2) 12% More efficient than Base Code¹ ( b.2) ¹ PV credit may be applied to meeting the minimum T24 Energy Code. Therefore, a higher percentage reduction is required for single-family and multi-family Option 2 to normalize the requirements compared to single-family and multi-family Option 1. 20

20 Single Family Residential Reach Code Measures Refrigerant Charge Verification (HERS) Verifies that the air conditioning and heat pump system s refrigerant is properly charged Quality Insulation Installation (HERS) Verifies the quality of insulation installation and air leakage control Piping Insulation, all hot water lines Insulating the pipes that carry hot water from your water heater to your various faucets when replacing your hot water system 21

21 Multi-Family Residential Reach Code Measures Quality Insulation Installation (HERS) Verifies the quality of insulation installation and air leakage control Refrigerant Charge Verification (HERS) Verifies that the air conditioning and heat pump system s refrigerant is properly charged Piping Insulation, all hot water lines Insulating the pipes that carry hot water from your water heater to your various faucets when replacing your hot water system 22

22 Commercial Energy Reach Code Ordinance Improvements New Commercial No PV 10% More efficient than Base Code ( b.1) With PV Comply with minimum Base Code + Install a 5 kw or larger PV system 1 ( c.2) 1 Less than 5 kw PV system is not considered. 23

23 Commercial Reach Code Measures Cool Roof White colored roofing materials have high solar reflectivity and low thermal absorption Daylight dimming & on/off lighting controls Ability to regulate the level and quality of light in a given space for specific tasks or situations Economizer An economizer is similar to a smart monitor that adjusts the building s heating 24 and cooling system based on the weather

24 Continuation of Energy Reach Code Existing Requirements Solar Ready Infrastructure for new homes Designated roof area of 500 square feet to enable future installation of solar power system Installation of conduit extending from the roofline to the electrical panel for future solar power wiring Exceptions for properties with protected trees in sync with the Solar Shade Act of 2009 and the Palo Alto Tree Ordinance 25

25 Exemptions & Infeasibility Electrification Reach Code allows for an exemption if the building pursues an all-electric design Compliance barriers exist in the energy to model software Heat Pumps Latest compliance software (CBECC-Res Alpha) shows minimal issues over previous energy penalty concerns Infeasibility exemption Allowing staff to permit alternative measures where strict compliance is not feasible or cost effective 26

26 Tons CO2e Emissions Annual Greenhouse Gas Savings 1,400 1,200 1, All Building Types T24 Part 6 Palo Alto Reach Code 6% Savings, or 71 tons/year *Based on 2015 Building Permit Data 27
