Cabrillo at First Mixed-Use Residential <br /> Air Quality, Global Climate Change, HRA, and Energy Impact Analysis <br /> 70 19386 <br />Energy efficient buildings require less electricity; therefore, increased energy efficiency reduces fossil fuel <br />consumption and decreases greenhouse gas emissions. <br /> <br />Per Section 100 Scope, the 2019 Title 24, Part 6 Building Code now requires healthcare facilities, such as <br />assisted living facilities, hospitals, and nursing homes, to meet documentation requirements of Title 24, Part 1 <br />Chapter 7 – Safety Standards for Health Facilities. A healthcare facility is defined as any building or portion <br />thereof licensed pursuant to California Health and Safety Code Division 2, Chapter 1, Section 1204 or Chapter <br />2, Section 1250. <br /> <br />Section 120.1 Ventilation and Indoor Air Quality included both additions and revisions in the 2019 Code. This <br />section now requires nonresidential and hotel/motel buildings to have air filtration systems that use forced air <br />ducts to supply air to occupiable spaces to have air filters. Further, the air filter efficiency must be either <br />MERV 13 or use a particle size efficiency rating specific in the Energy Code AND be equipped with air filters <br />with a minimum 2-inch depth or minimum 1-inch depth if sized according to the equation 120.1-A. If natural <br />ventilation is to be used the space must also use mechanical unless ventilation openings are either permanently <br />open or controlled to stay open during occupied times. The 2019 version of the Code also completely revised <br />the minimum ventilation requirements including DVC airflow rates within Section 120.1 Table 120.1–A. Table <br />120.1-A now includes air classification and recirculation limitations, these are based on either the number of <br />occupants or the CFM/ft2 (cubic feet per minute per square foot), whichever is greater. <br /> <br />Section 120.1 Ventilation and Indoor Air Quality also included additions for high-rise residential buildings. <br />Requirements include that mechanical systems must provide air filters that and that air filters must be MERV <br />13 or use a particle size efficiency rating specified in the Energy Code. Window operation is no longer a <br />method allowed to meet ventilation requirements, continuous operation of central forced air system handlers <br />used in central fan integrated ventilation system is not a permissible method of providing the dwelling unit <br />ventilation airflow, and central ventilation systems that serve multiple dwelling units must be balanced to <br />provide ventilation airflow to each dwelling unit. In addition, requirements for kitchen range hoods were also <br />provided in the updated Section 120.1. <br /> <br />Per Section 120.1(a) healthcare facilities must be ventilated in accordance with Chapter 4 of the California <br />Mechanical Code and are NOT required to meet the ventilations requirements of Title 24, Part 6. <br /> <br />Section 140.4 Space Conditioning Systems included both additions and revisions within the 2019 Code. The <br />changes provided new requirements for cooling tower efficiency, new chilled water-cooling system <br />requirements, as well as new formulas for calculating allowed fan power. Section 140.4(n) also provide a new <br />exception for mechanical system shut-offs for high-rise multifamily dwelling units, while Section 140.4(o) <br />added new requirements for conditioned supply air being delivered to space with mechanical exhaust. <br /> <br />Section 120.6 Covered Processes added information in regards to adiabatic chiller requirements that included <br />that all condenser fans for air-cooled converseness, evaporative-cooled condensers, adiabatic condensers, gas <br />coolers, air or water fluid coolers or cooling towers must be continuously variable speed, with the speed of all <br />fans serving a common condenser high side controlled in unison .Further, the mid-condensing setpoint must <br />be 70 degrees Fahrenheit for all of the above mentioned systems. <br /> <br />New regulations were also adopted under Section 130.1 Indoor Lighting Controls. These included new <br />exceptions being added for restrooms, the exception for classrooms being removed, as well as exceptions in <br />regard to sunlight provided through skylights and overhangs. <br /> <br />Section 130.2 Outdoor Lighting Controls and Equipment added automatic scheduling controls which included <br />that outdoor lighting power must be reduced by 50 to 90 percent, turn the lighting off during unoccupied <br />times and have at least two scheduling options for each luminaire independent from each other and with a 2- <br />hour override function. Furthermore, motion sensing controls must have the ability to reduce power within <br />15 minutes of area being vacant and be able to come back on again when occupied. An exception allows for <br />lighting subject to a health or life safety statute, ordinance, or regulation may have a minimum time-out period <br />706/27/2022 <br />Planning Commission 2 –123
