2 This chapter details how the City of Redondo Beach (City) will meet its energy and greenhouse gas (GHG) reduction targets by using goals, measures, and actions. The goal describes the overarching objective related to increasing energy efficiency or decreasing energy consumption, such as increasing energy efficiency in residential building units. Each goal contains one or more measures indicating the City s commitment toward meeting the goal. The energy and GHG reduction potential in 2020 and 2035 are identified for each measure. Measures are further divided into one or more discrete actions that the City may take in achieving the measure. Actions are designed to include the steps needed to implement the measure and are considered essential to guiding staff in implementation. Actions may be added or removed over time, depending on their relevancy, funding availability, and whether the actions are successful in supporting measures as they are monitored over time. Actions include a performance indicator, implementation timeframe, department, or agency responsible for implementation, and cost information, where applicable. In addition, co-benefits for each measure are indicated by the following icons: Energy Efficiency/ Reduced Energy Demand Improved Air Quality Energy Efficiency Education Water Conservation Increased Renewable Energy Sustainable Land Use Goals Overview The following is a brief overview of the City s Goals for the community sector. Goal, measure, and action details are provided within this chapter: Residential Energy o o Goal 1: Increase Energy Efficiency in Existing Residential Units Goal 2: Increase Energy Efficiency in New Residential Development Commercial Energy o o Goal 3: Increase Energy Efficiency in Existing Commercial Units Goal 4: Increase Energy Efficiency in New Commercial Development Water Efficiency o Goal 5: Increase Energy Efficiency through Water Efficiency Advanced Goals Goal 6: Decrease Energy Demand through Reducing Urban Heat Island Effect

3 Residential Energy Goals and Measures Residential Energy includes electricity and natural gas consumption within households in the City. There are many opportunities to save energy from existing and future development, described in the goals and measures below. Goal 1: Increase Energy Efficiency (EE) in Existing Residential Units California s first energy efficiency standards, known as Title 24 Standards, were adopted in 1977 and became effective in Title 24 standards have been updated every 2 to 5 years, creating increasingly stringent energy efficiency requirements for new construction. Approximately 71 percent of the City s housing stock was constructed prior to Therefore, there are tremendous opportunities to increase the efficiency of existing residential buildings through a range of measures that the City is currently implementing or will implement through this EECAP. They are described below. Measure 1.1: EE Training and Education Opportunities for residents to improve energy efficiency in their homes range from changes to behavior that they can start today to physical modifications or improvements they can make to their homes. Education of both the public and municipal employees is at the core of attaining energy efficiency goals. While most of the other measures include an outreach component, creating a specific education measure will emphasize the critical role of education in achieving energy efficiency. An education measure will also provide City staff with a framework to educate community members about behavioral and technological changes that can increase energy efficiency. 2

4 Post links on website/social media and provide materials at public events list for blasts of new information or trainings Establish an annual EE Fair Create a resource center Hire/Designate Energy Advocate Partner with South Bay Cities Council of Governments (SBCCOG) and Utilities to obtain educational content Measure 1.2: Increase Participation in Existing EE Programs MTCO2e MTCO2e 78,373 kwh 4,620 Therms There are opportunities for energy efficiency that are low-cost for residents to initiate and result in costsavings over time. These opportunities are generally from existing programs. In the South Bay, both Southern California Edison (SCE) and Southern California Gas Company (SCG) offer many rebates and other incentives to purchase energy efficient appliances, lighting, and other low cost investments that facilitate energy efficiency. Through this measure, the City will work to increase residents participation in existing energy efficiency programs that are low-cost or even provide a financial benefit to the resident. These are considered low-hanging fruit, but many residents may be unaware that they exist. As part of the South Bay Energy Efficiency Partnership with SCE and SCG, the City will continue outreach efforts that are largely led by the South Bay Cities Council of Governments (SBCCOG) to promote energy awareness and existing programs and incentives that are offered for energy efficiency. Some examples of programs and resources are listed below: 3

5 Rebate programs through SCE and SCG for appliances, air conditioner alternatives, electric water heaters, light bulbs, space heaters, water heaters, pool heaters, showerheads, washers, and insulation. Demand Response programs through SCE that provide on-bill credits including the Summer Discount Plan and Save Power Days Program. Technical and financial assistance programs through SCG s Direct Install Weatherization Program for income-qualified renters and homeowners. As programs change over time, continuous and up-to-date outreach is necessary. The actions detailed below would provide a variety of channels for ongoing communication to the City s residents. Action: Partner with SBCCOG and Utilities for outreach events Measure 1.3: Establish, Promote, or Require Home Energy Evaluations Home energy evaluations are necessary to identify cost-effective opportunities for energy savings and for residents to take practical actions to achieve energy efficiency Home energy evaluations can be established and/or promoted through a variety of existing programs. 4

6 Require third-party inspector to verify Title 24 or greater compliance to home upgrades (Alternative: Enhanced enforcement of Title 24 compliance) Promote home energy audits through programs such as Energy Upgrade California or other State programs Establish free "Energy Checkup" program with the assistance of the SBCCOG if funding can be obtained. Measure 1.4: Promote, Incentivize, or Require Residential Home Energy Renovations ,862 MTCO2e ,096 MTCO2e Estimated Demand Reduction in ,774,141 kwh 417,341 Therms Approximately 71 percent of residential buildings in the City were built before the adoption of Title 24. Buildings built before adoption of Title 24 are not energy efficient, and renovations would achieve higher energy efficiency. Many programs and incentives across the state or country help promote home energy renovations, including city-supervised funding, permit process improvements and city ordinance. Promote existing incentivized programs such as Energy Upgrade California Promote Financing Programs such as PACE (Properly Assessed Clean Energy) Establish online permitting to facilitate permit processing 5

7 Goal 2: Increase Energy Efficiency in New Residential Development California s current energy efficiency standards for buildings, called the 2013 Title 24 Standards, became effective July 1, 2014 and include significant changes to energy efficiency requirements in new development (see box). 1 Title 24 Standards are scheduled for updates and improvements every 3 years with the ultimate goal of zero net energy for new homes by Because of the update schedule, rulemaking process, and applicability dates, it is possible to implement proposed or adopted energy efficiency mandates before they are legally required. The City can implement early adoption of energy efficiency requirements through the following measure Title 24 Standards for Residential Construction include new requirements related to: Solar Readiness Verified AC Installation Hot Water Pipe Insulation Window Standards Insulation Standards Lighting Requirements HERS Verifications Requirement for Ventilation Vertical Fenestration Products and Skylights Measure 2.1: Encourage or Require EE Standards Exceeding Title

8 City planners have a unique opportunity to encourage/inform developers of new energy efficiency opportunities in new development. This measure will develop City staff to become resources in encouraging and implementing energy efficiency building measures beyond that required in current Title 24 Standards. As part of the 2010 California Green Building Standards (CALGreen), a two-tiered system was designed to allow local jurisdictions to adopt codes that go beyond state standards. The two tiers contain measures that are more stringent and achieve an increased reduction in energy usage by 15% (Tier 1) or 30% (Tier 2) beyond Title 24. This measure will also ensure that as Title 24 Standards are updated, City staff are well-informed and can implement updates quickly and effectively. Establish online permitting to facilitate permit processing Commercial Energy Goals and Measures Commercial Energy includes electricity and natural gas consumption for businesses in the City. Opportunities to save energy from existing and future development are described in the goals and measures below. Goal 3: Increase Energy Efficiency in Existing Commercial Units The City contains approximately 16,477,689 square feet of commerical and industrial buildings. It is estimated that, in California, approximately 80 percent of commercial buildings were constructed more than 50 years ago and prior to California s first adoption of the Title 24 Standards. 3 Given the age of the existing commercial building stock, there are opportunities to increase the efficiency of commercial buildings through a range of measures. Measures that the City is currently implementing or will implement through this EECAP are described below. 3 Source: Only 276,720 out of 1,310,143 commercial buildings in California are less than 50-year-old, meaning most of the commercial building are built at least before

9 Measure 3.1: EE Training and Education Education is at the core of attaining energy efficiency goals. Creating a specific education measure will emphasize the critical role of education in achieving energy efficiency. An education measure will also provide City staff with a framework to interact with and educate community members about behavioral and technological changes that can increase energy efficiency.

10 Measure 3.2: Increase Participation in Existing EE Programs MTCO2e ,369 MTCO2e 1,934,443 kwh 17,049 Therms There are many energy efficiency opportunities that are low-cost for businesses to initiate and result in costsavings over time. These opportunities are generally from existing programs offered in the South Bay. Both SCE and SCG provide many rebates and other incentives to purchase energy efficient appliances, lighting, and other low cost investments that facilitate energy efficiency. Through Measure 3.2, the City will work to increase businesses participation in existing energy efficiency programs that are low-cost or even provide a financial benefit to the business. Although these are considered low-hanging fruit, many business owners may be unaware that the opportunities exist. As part of the South Bay Energy Efficiency Partnership with SCE and SCG, the City will continue outreach efforts to promote the energy awareness and existing programs and incentives that are offered for energy efficiency. These outreach efforts are largely led by the SBCCOG. Some examples of programs and resources are listed below. Rebate programs through SCE and SCG for appliances, air conditioner alternatives, electric water heaters, light bulbs, space heaters, water heaters, and insulation. Demand Response programs though SCE that provide on-bill credits including the Summer Discount Plan and Save Power Days Program. As programs change over time, continuous and up-to-date outreach will be necessary. The actions detailed below would provide a variety of channels for ongoing communication to the City s businesses. 9

11 Action: Partner with SBCCOG and Utilities for outreach events Measure 3.3: Promote or Require Non-Residential Energy Audits ,250 MTCO2e ,936 MTCO2e 3,052,912 kwh 51,425 Therms Commercial energy audits are necessary to identify cost-effective opportunities for energy savings and for business owners to take practical actions to achieve energy efficiency. The audits can be established or promoted through various existing programs. Require third-party inspector to verify Title 24 or greater compliance to upgrades Promote energy audits such as through Energy Upgrade California or other state programs 10

12 Measure 3.4: Promote or Require Commercial Energy Retrofits ,379 MTCO2e ,052 MTCO2e 39,185,638 kwh 535,680 Therms As most commercial buildings were built before the adoption of Title 24, most of the facilities and equipment are not energy efficient. Therefore, retrofits are necessary to achieve higher energy efficiency. Many programs and incentives across the State or country help promote non-residential energy retrofits, including city-supervised funding, permit process improvements, and city ordinance. Promote existing incentivized programs such as Energy Upgrade California Develop or promote a green building program Promote Financing Programs such as PACE (Properly Assessed Clean Energy) Establish online permitting to facilitate permit processing 11

13 Goal 4: Increase Energy Efficiency in New Commercial Development California s current energy efficiency standards for buildings, called the 2013 Title 24 Standards, became effective July 1, 2014 and include significant changes to energy efficiency requirements in new development (see box). 4 Title 24 Standards are scheduled for updates and improvements every 3 years with the ultimate goal of zero net energy for new commercial buildings by Because of the update schedule, rulemaking process, and applicability dates, it is possible to implement proposed or adopted energy efficiency mandates before they are legally required. The City can implement early adoption of the energy efficiency mandates through the following measure Title 24 Standards for Non- Residential Construction include new requirements related to: Solar Readiness Cool Roof Requirements Air Leakage Rate Standards Fenestration Requirements Insulation Standards Lighting Requirements Mechanical Requirements Receptacle Controls Requirements Additional Covered Processes Measure 4.1 Encourage or Require EE Standards Exceeding Title

14 City planners have a unique opportunity to inform developers of new energy efficiency opportunities and encourage them to adopt these technologies in new development. This measure will develop City staff to be resources in encouraging and implementing energy efficiency beyond that required by current Title 24 Standards. This will also ensure that as Title 24 Standards are updated, City staff are well-informed and can implement updates quickly and effectively. Establish online permitting to facilitate permit processing Water Efficiency Goals and Measures Water supply processes require energy consumption for water treatment and conveyance. The average energy intensity of water delivered to its customers by the Metropolitan Water District (MWD) of Southern California is 2,473 kwh/acre foot (AF). 6 Improving water efficiency can save energy, as described in the goal and measures below. Goal 5: Increase Energy Efficiency through Water Efficiency (WE) Water availability is and has been a vital economic resource, natural resource, and public health issue in California. Over the past 4 years, California has been facing one of the most severe droughts in the State s history. In January 2014, Governor Jerry Brown declared a drought State of Emergency, and issued Executive Order B (EO B-29-15) in April EO B directs the State Water Resources Control Board (SWRCB) to implement mandatory water restrictions in order to reduce water usage by 25 percent. Saving water is important, not only in helping mitigate drought conditions, but also to save energy. Every process of water supply and distribution requires energy, including water treatment, wastewater collection, and wastewater treatment. Reducing water usage and increasing water efficiency is key to increasing energy efficiency. 6 GEI Consultants/Navigant Consulting, Inc., Embedded Energy in Water Studies, Study 1: Statewide and Regional Water-Energy Relationship, August 31,

15 Measure 5.1: Promote or Require WE through SBX MTCO2e ,396 MTCO2e 2,235,594 kwh SB X7-7, or The Water Conservation Act of 2009, requires all water suppliers to increase water use efficiency. The legislation set an overall goal of reducing per capita urban water consumption by 20 percent from a baseline level by This goal can be met by taking a variety of actions, including targeted public outreach and promoting water efficiency measures such as low-irrigation landscaping. Additional water conservation information, resource materials, education, and incentives are available through the West Basin Water District. Post links on website/social media and provide materials at public events list for blasts of new information or trainings Require low-irrigation landscaping Partner with SBCCOG and Water District to obtain educational content Partner with SBCCOG and Water District for outreach events 14

16 Measure 5.2: Promote WE Standards Exceeding SB X MTCO2e MTCO2e 9,422 kwh In addition to SB X7-7, more actions are being studied or have been taken to exceed water efficiency standards. These efforts include education and outreach practices that could be combined with residential and commercial EECAP actions that emphasize the reuse of recycled/gray water and promote harvesting rainwater. Approximately 1,873 kwh can be saved for every acre foot (AF) of water use replaced by recycled water. 8 Allow recycled or grey water uses for non-municipal uses Work with Water District to increase recycled water potential Promote rainwater harvesting rebates and demonstrations 8 California Sustainability Alliance, The Role of Recycled Water in Energy Efficiency and Greenhouse Gas Reduction, May 2,

17 Advanced Goals and Measures Similar to other cities, the City is affected by the urban heat island effect, which results in higher temperatures and associated energy use. This phenomenon and measures aimed at addressing its impacts are further discussed in Goal 6. Goal 6: Decrease Energy Demand through Reducing Urban Heat Island Effect The urban heat island (UHI) effect is a daytime elevation in the outdoor urban air temperature that results in part from the replacement of trees and other vegetation with buildings, roads and other heat-absorbing infrastructure. The properties of urban roofs and pavements are the most important factors of UHI, since these surfaces are typically dark in color. Dark surfaces absorb more energy from sunlight than lighter surfaces and, therefore, get warmer than lighter colored surfaces. Very dark surfaces can absorb at least 80 percent of sunlight s energy. These warm roofs and pavements then emit heat and make the outside air warmer. Human activity is another significant contributor to UHI. Air conditioning, industrial manufacturing activity, transportation, and other human activities discharge heat into our urban environments. On a sunny summer afternoon, urban air can be 1-3 C (2-5 F) warmer than nearby rural air. (Source: Heat Island Group, Lawrence Berkeley National Laboratory) Urban heat islands can negatively affect the urban community and the environment. One of the most serious consequences of UHI is increased energy use. Warm temperatures in cities increase the need for air conditioning to cool buildings. This elevated cooling demand can strain the electrical grid on a hot summer afternoon, making the system more susceptible to brown-outs and black-outs. Environmental effects include impaired air quality that comes from the accelerated formation of smog because of warmer air, and human illness due to the higher temperatures and lower air quality. Efforts to reduce UHI are limited because of the lack of consciousness on this problem and limited technologies to eliminate the effect. There are, however, basic strategies and measures that the City can take to decrease the energy demand caused by UHI. 16

18 Measure 6.1: Promote Tree Planting for Shading and EE MTCO2e ,399 MTCO2e 921,139 kwh Co-Benefit Trees and plants naturally help cool an environment by providing shade and evapotranspiration (the movement of water from the soil and plants to the air), making vegetation a simple and effective way to reduce urban heat islands. Shaded surfaces may be F (11 25 C) cooler than the peak temperatures of un-shaded materials. In addition, evapotranspiration, alone or in combination with shading, can help reduce peak summer temperatures by 2 9 F (1 5 C). Furthermore, trees and plants that directly shade buildings can reduce energy use by decreasing demand for air conditioning. Encourage tree planting at plan check Work with community to develop a tree-planting group Develop a City tree planting program 17

19 Summary of Local Reductions By implementing these local reduction measures, the City would reduce its community GHG emissions associated with energy use by approximately 5% compared to the 2020 business-as-usual (BAU) emissions and 24% compared to the 2035 BAU emissions. Table 1 summarizes the energy efficiency strategies and the potential GHG reductions, and Figure 1 depicts the sectors where the anticipated reductions will take place with the corresponding potential decreases.

Local Reduction Quantification by Goal Comparison to Reduction Targets By 2020, the statewide and local measures together would reduce the City s community GHG emissions from the 2020 BAU condition by approximately 16% or 83,964 MT CO 2e (from 527,294 MT CO 2e to 443,330 MT CO 2e). This reduction is equivalent to a 15% decrease below the 2005 levels, which achieves the 15% reduction target of the year 2020, as depicted in Figure 2. Additional reduction measures through 2035, as selected by the City, would result in reductions below the 49% reduction target (from 2005 levels) and would require additional reduction measures in order to achieve the 2035 reduction target. Table 2 summarizes 19
