2 Provide permanently anchored bicycle parking and secure bike parking within 200 feet of entrance for 5% of both new visitor (one two-bike rack LEED is more stringent than CALGreen. CG Bicycle Parking minimum) and tenant vehicular parking spaces (one space minimum). The CALGreen measure prescribes a minimum number of secure bicycle parking spots (based on the number of parking spaces for the building) and defines their required distance from a building entrance. LEED goes much further to define minimum bicycle storage counts based on builidng Bike Storage: Provide secure bike storage within 100 feet of main entrance occupancy, including rules for visitors, FTEs and residents. For LEED, the distance of bike storage to a for 2.5% of all peak visitors (short-term) and 100 feet of any building entrance for 5% of non-residential FTE (long-term) and 30% of residential building entrance is half of the CALGreen requirement. And LEED requires shower/changing facilities where CALGreen mandatory measures do not. LTc6 Bicycle Facilities occupants. Locate storage within walking (200 yds) or cycling distance of a bicycle network that connects to various defined destinations that are located with a 3-mile cycling distance of the project boundary. Shower Facilities: Provide at least one shower and changing facility for first 100 FTE and one additional shower for every 150 FTE occupants thereafter. CG Designated Parking Electric vehicle (EV) charging LTc7 Reduced Parking Footprint LTc8 Green Vehicles Provide parking for any combination of low-emitting, fuel efficient, or carpool/van pool vehicles as referenced in table A (up to 8% of total) Provide electric vehicle charging stations for up to 3% of total parking spaces. Provide 5% designated carpool parking above and beyond the parking reduction requirements for any off street parking. Provide 5% "Preferred Parking" (carpool/vanpool not included) for green vehicles AND Provide EV supply equipment in 2% of all parking spaces. CALGreen and LEED are not aligned. The requirements among this cluster of CALGreen measures and LEED credits is out of sync. One CALGreen measure requires designated parking for low-emitting, fuel efficient, or carpool vehicles. The other sets a target for EV charging stations (3% of total parking spaces, compared to LEED's 2% threshold). One LEED credit requires designated carpool parking, but only after reducing the parking count based on ratios established by the Parking Consultants Council (a requirement CALGreen mandatory measures don't address). The other LEED credit requires preferred parking for "green vehicles" (no carpools included) and EV supply equipment for a percentage of spaces (less than the CALGreen requirement). 2

3 Design and install lighting systems to comply with CA Energy Code and CALGreen and LEED v4 are equivalent. CG Light Pollution Reduction meet IESNA TM BUG rating requirements. Both LEED and CALGreen use the IESNA 2011 BUG s to measure uplighting, backlighting, and Meet uplight and light trespass requirements using the IESNA TM glare. SSc6 Light Pollution Reduction BUG method. CG Grading and Paving Manage surface water flows to keep water from entering buildings. CALGreen does not have a LEED point for comparison. N/A N/A N/A CG Energy Efficiency EAp2 Minimum Energy Performance *EAc1 *Optimize Energy Performance Meet or exceed the requirements of the California Building Energy Efficiency Standards (Title 24, Part 6, 2016) Demonstrate an energy cost reduction compared to ASHRAE (5% New Construction, 3% Major Renovations, 2% Core and Shell) Use whole building energy simulation to demonstrate increased energy cost reduction compared to ASHRAE something CALGreen (Title 24, Part 6) is more stringent than LEED v4 (ASHRAE ). A report titled Energy Efficeincy Comparison: California's 2013 Building Energy Efficiency Standards and ASHRAE/IESNA Standard helps answer the question of which energy efficiency requirements are more stringent between CALGreen and LEED. That report concludes that estimated energy use for nonresidential buildings of California's 2013 Building Energy Efficiency Standards exceed the energy savings expected from the commercial building requirements of ASHRAE/IESNA Standard It is expected that this would remain true for a comparison to Title 24,

4 CG Meters Provide water submetering on buildings over 50,000 square feet or where LEED v4 is more stringent than CALGreen consumption is projected to be more than 1,000 gal/day. CALGreen requires projects over 50,000 square feet to install water submeters. The LEED prerequisite requires one building-level water meter--regardless of project size--and for the building Install permanent water meters that measure the total potable water use owner to share the water consumption data with the USGBC for 5 years. To earn the LEED credit for the building and associated grounds. Meter data must be compiled into for Water Metering, a project would need to install meters for at least one more subsystem such as WEp3 Building Level Water monthly and annual summaries; meter readings can be manual or irrigation, reclaimed water, or boilers. Metering automated. Whole project water usage data must be shared with the USGBC for a five year period. WEc4 Water Metering Provide permanent water meters for at least two of the following water subsystems: 1) Irrigation 2) Indoor plumbing fixtures and fittings 3) Domestic Hot Water 4) Boiler 5) Reclaimed water 6) Other process water Meet the following flow rate requirements: CALGreen is more stringent than LEED v Water conserving plumbing fixtures and fittings 1) WC: 1.28 gpf 2) urinal: 0.5 gpf 3) wall-mounted urinal: gpf 4) metering faucet for wash fountains: 0.2 gal/cycle 5) showerheads: 2 gpm On April 1, 2015, Governor Jerry Brown released Executive Order B mandating emergency regulations that would improve the efficiency of water appliances including toilets and faucets in CG WEp2 WEc2 Commercial Kitchen Equipment Standards for Plumbing Fixtures and Fittings Prerequisite: Indoor Water Use Reduction Indoor Water Use Reduction 25%-50% Meet the following flow rate requirements: 1) lavatory faucets: 0.5 gpm 2) kitchen faucets: 1.8 gpm 3) wash fountains: 1.8 gpm 4) wash fountains: 0.2 gal/cycle 5) metering faucet for wash fountains: 0.2 gal/cycle Install plumbing fixtures in accordance with the California Plumbing Code. Reduce water consumption by 20% from a baseline. Address fixtures & fittings, appliances, equipment, and processes. Further reduce fixture and fitting water use from the calculated baseline in WEp2. new and existing buildings. CALGreen sets maximum prescriptive flow rates for bathroom and kitchen plumbing fixtures, while LEED follows a performance approach with a water budget. CALGreen builds off the California Plumbing Code updates, with fixture flow rates now more stringent than LEED. On average, California's fixture requirements are 28% lower than LEED's baseline requirements. The amount of potable water reduced against LEED's baseline would vary project to project, as it depends on the final count of fixtures throughout the building. But it is reasonable to expect a project meeting CALGreen requirements would easily achieve the LEED prerequisite for Indoor Water Use Reduction and also earn 2 points for a 30% reduction under the LEED credit. 4

5 Comply with the California Model Water Efficiency Landscape Ordinance CALGreen (MWELO) is more stringent than LEED v4 (EPA WaterSense). CG Outdoor Water Use (MWELO) contained within Chapter 2.7, Division 2, Title 23, California Code of Regulations In response to Califorinia's drought, the state's irrigation requirements have become more stringent than LEED. Landscape irrigation must meet the Model Water Efficiency Landscape Ordinance Option 1: No irrigation required. (MWELO). This ordinance, like LEED, sets a maximum allowable water allowance for a project site WEp1 Prerequisite: Outdoor Water Option 2: Reduce irrigation demand by 30% from a calculated baseline based on local evapotranspiration. The method for establishing this water budget is identical between Use Reduction using the EPA WaterSense Water Budget tool. MWELO and LEED's WaterSense approach. MWELO requires a water use reduction between 45-55%, depending on site use conditions, and also requires an audit report to be filed from a certified Option 1: No irrigation required. landscape irrigation auditor. WEc1 Option 2: Reduce irrigation demand by 50% (1 point) or 100% (2 points) Outdoor Water Use from a calculated baseline using the EPA WaterSense Water Budget tool. LEED's prerequisite requires a 30% reduction from a baseline, easily achieved by designing to the Reduction MWELO standard. Further, it's reasonable to expect a MWELO compliant project to earn at least 1 point for a 50% reduction in outdoor water use.

6 CG-2016 Develop a Construction and Demolition Waste Management Plan and CALGreen and LEED are not aligned, but they are similar Construction Waste identify a 65% diversion goal. Use a waste management company to Management provide verifiable documentation. Both CALGreen and LEED require development of a Construction and Demolition Waste Management Plan. CALGreen requires the plan to identify a 65% Diversion goal, where the LEED Items like batteries, electronic devices, mercury-containing equipment, prerequisite only requires an estimate. CALGreen requires the use of a waste management company Universal Waste lamps, cathode ray tubes, and aerosol cans must be disposed of properly to provide verifiable documentation and LEED does not. and diverted from landfill. The LEED credit has two options. For one point, a project must divert 50% of three material streams Develop a Construction and Demolition Waste Management Plan. Identify or 75% of four material streams for two points. Excavated soil, land clearing debris and alternative MRp2 at least five materials for landfill diversion. Estimate their contribution to daily cover (ADC) must be excluded from diversion calculations for both CALGreen and LEED. Construction and Demolition overall project waste. Specify diversion strategies and identify recycling Waste Management Planning facilities. Both CALGreen and the LEED credit provide an alternative waste reduction strategy that allows the project to comply by not generating more than 2 lbs or 2.5 lbs of construction waste per square foot Option 1: Divert 50% of waste and 3 material streams (1 point), or 75% of of building's floor area respectively. MRc5 Construction and Demolition waste and 4 material streams (2 points). Waste Management Option 2: Generate less than 2.5 lbs/sf of construction waste CG Recycling by occupants MRp1 Storage and Collection of Recyclables Provide areas that serve the entire building and are identified for the depositing, storage, and collection of nonhazardous materials for recycling and organic waste. Provide dedicated areas for the collection and storage of recyclable materials, including mixed paper, corrugated cordboard, glass, plastics, and metals, batteries, mercury-containing lamps, and electronic waste. CALGreen and LEED v4 are equivalent. CALGreen and LEED have nearly identical recycling requirements. CALGreen requires organic waste, where LEED does not. The USGBC has deemed the CALGreen measure and the LEED prerequisite to be functionally equivalent. See the CALGreen Alternative Documentation Path Guidance Document (2015) for further information. 6

7 For new buildings > 10,000 sf, commission all systems covered by Title 24, CALGreen and LEED are not aligned, but they are similar. Part 6, including process systems and renewable energy systems. Provide a CG Commissioning (Cx) systems manual and training on commissioned systems. CALGreen and LEED both require commissioning of all energy-related systems. CALGreen requires that irrigation systems be commissioned. CALGreen also requires development of a systems manual and training on systems being commissioned. The LEED credit requires the OPR, BOD and peer Commission MEP and renewable energy systems. review address the exterior envelope. LEED has more stringent requirements for the Commissioning Fundamental Commissioning EAp1 Agent (CxA), and for projects >20,000 sf, the CxA must be independent of the design team. and Verification CALGreen has more relaxed requirements for qualified commissioning agents and only requires Commission MEP and renewable energy systems. More stringent independence on projects >50,000 sf EAc1 Enhanced Commissioning requirements for CxA CG Testing and Adjusting EAp1 Fundamental Commissioning and Verification CG Fireplaces Test and adjust systems for buildings less than 10,000 square feet. Provide a final report. Provide building owner with a detailed operating and maintenance instruction manual. Commission MEP and renewable energy systems. Install only a direct-vent sealed combustion or sealed wood-burning fireplace, or a sealed woodstove or pellet stove, and meet California Energy Code, Title 24, Part 6 residential requirements. LEED is more stringent than CALGreen. LEED requires commissioning (not just testing and adjusting) of all energy-related systems in all projects regardless of size. Therefore, LEED is more stringent than CALGreen. However, CALGreen requires testing and adjusting of irrigation systems, which LEED does not address. CALGreen does not have a LEED point for comparison. N/A N/A N/A Use return air filters with a MERV of 8. Replace filters before occupancy.

Performance CALGreen does not have a LEED point for comparison. LEED v4 is more stringent than CALGreen. CALGreen (Title 24 Energy Code) and LEED (ASHRAE) use different reference standards, but they are similar and have the same intent. The ASHRAE standard is more restrictive since it considers air distribution effectiveness and ventilation efficiency. CG Carbon dioxide (CO2) monitoring For buildings with demand control ventilation, install systems in accordance with California Energy Code. LEED v4 is more stringent than CALGreen.

CG Acoustical Control ASTM Use either a prescriptive or performance method. CALGreen focuses on the exterior noise control, site based mitigation and interior sound transmission primarily from the perspective of building materials. LEED addresses HVAC background noise, reverberation and interior sound transmission. The interior sound transmission thresholds in EQc9 Acoustic Performance Meet requirements for HVAC background noise, sound isolation, reverberation time, and sound reinforcement & masking. LEED are more stringent than those required by CALGreen. Install HVAC and refrigeration systems that don't contain CFCs, Halons, CALGreen and LEED are equivalent. CG Ozone depletion and greenhouse gas reductions or HCFC. HFCs must have a global warming potential of less than 150.
