It is designed to help residents, homeowners, building owners, designers, architects, contractors, developers and building officials determine how they can design their building or remodeling plans to include 'green building' techniques and products. Green building is a strategy that takes a comprehensive approach to achieving efficiency through design, construction, renovation, and operation by creating structures that are resource efficient and environmentally sound. The central objective of green buildings is to use resources, including building materials, electricity, and water, efficiently, Green buildings also tend to have better indoor air quality, thereby improving the health of people who live or work in them relative to traditional buildings. Another benefit is that the cost of operating and maintaining green buildings is less compared to their traditional counterparts. Green building strategies save money, improve the profit margin for local businesses, and free up dollars which would otherwise have been spent on utilities. Finally, green buildings enhance the local environment and quality of life, and increase the livability of the community. BACKGROUND Buildings and structures use energy, water and raw materials and generate waste in the form of wastewater, refuse (solid waste), and demolition materials, The production and use of materials and energy as well as the disposal of waste results in the emission of air pollutants and greenhouse gases. Minimizing the use of these resources through green building principles -- such as using material that are recycled and energy sources that are renewable— helps to reduce impacts to our environment and promotes sustainability. There are a number of methods to achieve energy efficiency in buildings and structures, including passive solar design, heating, ventilation, and air-conditioning systems, and selection of building and landscaping materials. While the definition of green building or sustainable building can be described in a number of ways, the following are fundamental principles that are considered when designing a green building or retrofitting an existing building: - Site Integration (location and building orientation) - Efficient use of resources (water, natural gas, electricity) Material selection, building products, and appliances • Indoor air quality and ventilation Efficient operation and maintenance Introduction, Voluntary Green Building Manual WHO CAN TAKE ADVANTAGE OF THISUAL?' If you are building or remodelinga home or a commercial property, the techniques and products in this Manual are meant to help you build a more energy efficient, environmentally friendly structure. This Manual is intended to be used by: Homeowners • Building owners . Renters, Lessees, and Tenants • Developers . Architects and designers Builders, contractors and building trades • Planners, practitioners and city officials The goal of this Manual is to provide a one -stop shop for those who choose to participate in green building by making information readily available and easy to understand. PURPOSETHIS L This Manual is intended to provide guidance to those wishing to increase the energy efficiency of their home or workplace. This manual goes beyond eniz v A ;noant-w ¢n nA race- ^fKnr nL nr+L- f t built environment such as indoor air quality. In addition,' the beneficial use of naturally occurring processes such placement of awning or solar water heating, or water impermeable surfaces and designing catchment basin to users to green building concepts, provides a point By to achieved, described incentives and resources available l+ o e imize )priate iing dikes ,iency the permitting process, A WORD (or two) Whetter your project is a new building or a remodel of an existing structure, you will need a building permit, AND California building energy efficiency standards will apply. We know that understanding the process, let alone the principles, can be difficult, but the goal is simple reduce energy consumption. The Voluntary Green Building Program and the checklist of design' strategies in Chapter Three of this Manual do NOT take the place of the Energy Efficiency and Green Building Sections of the California Building Mode (CBC), Part 11 of the California Green Standards Code, or Title 24 Part 6 of the California Energy Code. "Title 24" is the term commonly used to describe energy regulations for buildings in California. Since 1978 design professionals, contractors and building owners have had to comply with the energy efficiency measures contained in Part 6 of Title 24, The requirements to comply have been revised numerous times during the past thirty years, and they will continue to be revised to reach the ultimate goal of "net zero. Introduction: Voluntary Green wilding Manual 2 Of course, a building constructed today is much more efficient than one constructed twenty years ago. The minimum goal of the Voluntary Green Building Program is to exceed TOA Y'S mandated energy performance by 15% (per Title 24 Bart 6 calculations 2008), Historically, to demonstrate that a building meets California energy efficiency standards, a design professional or energy consultant would use software to compare the energy efficiency of a proposed building with a theoretical "baseline energy budget. " The deing professional would select the various elements within a building (glazing, insulation, roofing, HVAC equipment, etc.) and the software spits out the annual energy usuoge in the specific climate zone (mountain, desert, coast). If the projected energy usage is less than the "baseline," the building would "comply, " In 2010, Title 24 was amended to include "green building" requirements. These requirements are contained in Part 11 of Title 24, and are called the "California Green Standards Code (CALGreen)." Part 1 I views the entire process of design and construction from a broader perspective and includes issues; dealing with construction waste, recycled materials, and water usage. Virtually any new construction, remodel, alteration or addition to an existing structure must comply with both fart 6 (energy calculations) and Part 19 (Green wilding) of Title 24, This Manual supplements those requirements, but does not replace them.' HOW TO USE THIS MANUAL This Manual is organized into the following Chapters: Chapter 1: The Practical Approach, "What Should I Do Now?" Chapter 2: The Informative Approach, Green Principles Illustrated Chapter : The Technical Approach, Understanding Green Building Codes and Credit Checklist Chapter 4; Financial Analysis Chapter 5. Financial; Incentives and Permit Processing The first task in using this Manual is to identify the building type to which green building concepts will be applied. Each chapter contains information specific to residential and commercial buildings (for ease of use, all non-residential buildings are termed commercial). Information for residential buildings is subdivided into single family and multi family structures. The residential and commercial sections are further broken out into existing buildings (retrofit) and new buildings. Once you've identified your building type you can go directly to the appropriate section in each Chapter. The next step is to browse through the menu of green building options and become familiar with green building concepts. This will allow you to select improvements that will be most beneficial to your needs. You should also talk to your designer, architect or contractor about these options, and work with therm to develop a list of the items you want to include. In order to reach the first level — 15% over "Title 4", you will need to incorporate the improvements shown in green in Chapter 3. Your designer or contractor can help you select the items you need to reach that level, The additional improvements listed will help you reach higher energy efficiency levels, which are described below. w. Introduction; Voluntary Green wilding Manual 3 OVERVIEW OF CHAPTERS Chapter One; The Practical Approach, provides information on how to use this Green Building Manual and explains who can use it, what it can be used for and hew to implement it, This chapter provides a quick overview of practical steps to improve energy -efficiency and save money, Chapter One also provides a glossary of terms for easy reference and graphic images that explain green building concepts, ;Chapter One asks "What should I do now?" and provides basic answers for each of the building types addressed, If you are new to green building principles, Chapter Two: The Informative Approach; introduces concepts such as solar orientation" building envelope, and passive energy conservation, Green building principles include a number of common and more specialized concepts, It also introduces the green building categories that are used to evaluate the level of energy savings achieved, This Chapter enables the homeowner, tenant, designer, 'builder i or developer to become familiar with various aspects of green building, Each concept is tied to specific green building techniques in Chapter Three, Chapter Three; The Technical Approach, provides the technical guidance and parameters to consider when using green building principles, This chapter provides the detailed menu of sustainable design options and the credit attributed to each measure, The menu items are organized by the fallowing 'categories: Site, Envelope, Equipment; Passive Energy Conservation, and Materials, Each category contains several green building measures that correlate to the point system. All the measures that have a green background are specific to increasing your energy efficiency by 15% over "Title 24", POINT SYSTEM (CHECKLIST IN CHAPTER The ultimate goal of the GFL. Voluntary Green Building Program is to reduce energy usage in buildings, The "Checklist" in Chapter Three includes;a broad range of choices you can make that will achieve that goal, Each choice contributes to reducing energy usage, Some choices like higher efficiency air conditioners simply use less energy, other choices like planting shade trees are less direct, but still work, Keep in mind the difference between direct energy savings (higher efficiency equipment) and indirect energy savings (shade trees), The choices related to direct savings, highlighted in dark; green; are counted as "Total Energy Efficiency Measures," and these choices are also part of the California Energy Code, (Title 24, Part 6 in Beek language,) Choices that are more indirect, not highlighted, are counted as "Total Sustainable ensures," The basic level to comply with Voluntary green Building Program, the choices you make in the direct Introduction: Voluntary Green Building Manual 4 The next two levels (Green Branch and Green Tree) require choices that are more wholistic in addressing energy usage. These choices are called "Green Building" or "Sustainable Building" choices and contribute indirectly. They are not part of the actual calculations used in the "Title 24" forms, The choices you make are given various "points" toward the "Total Sustainable Measures," and as you select those you Wish to include in your project, the points are tabulated, Green Branch requires 40 points in addition to those for the Green Leaf . Green Tree requires you to include measures that add another 20 points above Green Branch . Chapter 4 offers a cost benefit analysis to help determine the most appropriate measures to apply for specific budgets. You can use this tool to determine the cost of the measures you have chosen, and how long it will take for these measures to pay for themselves. Rebates, discounts, and financial incentives as they relate to green building are described in Chapter 5: Financial Incentives and Permit Processing, Since incentives change regularly, depending on the offers being made by the State and federal governments, and individual utilities, this chapter gives you links to government and utility web sites to check on the latest programs available, As part of this program, the City/Tribe has committed to making it easier for those participating in the program to process their plans and receive permit approval. In the case of remodeling and retrofitting plans, only building permits will be required. When a new residential or commercial project is proposed, that new project will be subject to standard environmental review, However, projects that show a commitment to Green Building and achieve targeted savings will benefit from fast tracking and reduced permitting costs for building permits, Online Version If viewing electronically, direct links to each building type and subcategory are provided. Simply click on the desired chapter to be routed to the appropriate discussion, INSPECTIONS This Program is self -reporting (except for the "Title 24" credits.) It is based upon an honor system: you say you are going to do something to improve the energy efficiency of your building, and we assume you will. However, there is great value to have third party verification of the actual installation of various measures. Now, why do we say we will trust you, but not the contractor? Simply because the complexities and idiosyncrasies of every construction project present challenges to contractors. Sometimes they miss something, overlook something or simply make a mistake, It is in your interest to confirm that what the plans and specifications state, and what you pay for, are actually well -executed, Introduction: Voluntary Green Building Manual 5 -1- . .... .. Therefore both the California Energy Code and this Manual place high value on third party verification of four major elements: insulation, duct and whole house leakage, and HVAC equipment, The first three require careful attention to details and connections, and not infrequently do not perform as designed, By inspecting them before they are closed up (so errors can be corrected), the overall performance of the building is greatly enhanced. Every process of manufacturing and fabrication requires quality control; you can think of third -party verification as construction quality control, WHERE ELSE TO LOOK FOR INFORMATION Energy conservation is on everyone's mind, but it isn't always easy to find your way around all the programs and websites, Below are links to some of these organizations — ones we think are especially relevant to our Desert Climate. By no means is the list complete, but it will get you started looking for more information — or the same information presented differently, The first links are Federal Programs, then state, then non-profit and finally industry, CODE REFERENCE: These links provide additional information on the source codes used in Chapter 3, You can learn about the principles to make your building "green" and how to apply the principles.

CHAPTER ONE provides a quick overview of practical sups to improve energy -efficiency and save money, CHAPTER ONE asks "What should 1 do now?" and provides basic answers for each of the building types addressed in the Voluntary Green wilding Manual; Single family homes Multi -family apartments Commerical buildings CHAPTER ONE also includes a simple glossary of terms commonly used in energy -efficiency literature and the green budding design and construction industry. Some low- or no -cost steps one can take right now. NO T OR LOW COST IMPROVEMENTS These measures to reduce energy use are either lour cost or no cost options that everyone should consider, I , Seal Leaks: eliminating air leaks in buildings by checking window and door seals helps to regulate the temperature differential between indoors and outdoors. ?. Replace light bulbs: the use of compact fluorescent light bulbs reduces energy casts while proving the same level of illumination. 3. Turn off lights and appliances and shut off power source: turning off lights and appliances when not in use is a quick and easy way to save energy. The use of power strips can further reduce energy use by avoiding the ghost effect caused by unused electronics. Some mechanisms, such as cable TV boxes, utilize almost as much pourer when in the off position as when the TV is on. Automate the thermostat, lights and vending machines: Programmable systems allow for automation so that energy is conserved during non -business hours or during low use. Maximize heat and light from the sun. Natural daylight can be sufficient to provide co r adequate light for certain activities. Open curtains and blinds in south and west facing windows for heat and light, or close them to keep cooler. Chapter 1, The Practical Approach 9 ..................... .... . .. .... . . GLOSSARY' . . ...... . .. . What should I do now? COOL ROOFING requires high solar reflectance and emissivity, ROOFING Reflectance measures how much of sunlight (visible, infrared and Solar Reflectance ultraviolet) is reflected, > 0,70 Emissivity measures how easily heat is radiated by a material. Emissivity INSULATION slows the transfer of heat. The thermal resistance of a INSULATION material is measured in "R value"; higher is better. In our desert climate R-Values R-38 is good in the attic and R-19 in the walls. WINDOW thermal performance is measured in three ways- controlling WINDOWS sunlight (SHGC), conductance and infiltration, Solar Heat Gain Coefficient (SHGC) measures how much sunlight heats SHGC up the interior; lower is better, < 0,30 U-value measures the conductance of the entire window assembly U-Factor (glazing and frame), Performance is expressed as "Ll-factor'; VENTILATION is necessary for a healthy interior, but buildings are VENTILATION increasingly "tight," They don't leak much, so fresh air has to be brought Tight Buildings into the house when the AC is running, The amount of fresh air is Air Changes/Hour measured in Air Changes per Hour (ACH) and is verified by blower door test.

In this Chapter the principles of energy efficiency and resource management are illustrated and explained in everyday language. This Chapter is geared toward property owners and interested citizens more than to professionals The principles are organized from the outside — in. Issues related to the site and existing conditions are addressed first, then the envelope of the building, then equipment and systems, and finally passive strategies. Each page illustrates two or three related principles. While the graphics and text are intended to present a basic understanding of an issue, at the bottom of the page are noted the reference numbers for specific technical Items listed in Chapter 3. In addition, the Appendix contains source references for more information, Principles of energy efficiency are illustrated for both remodel and new construction and for all three building types (single family residences, multi -family buildings and commercial buildings, and are coded by color with a lighter shadefor remodel, and darker for new. At the beginning of each building, type; is a sheet titled "What Should I Do Now?" which presents simple steps to consider for remodel projects but are also relevant to new projects. The ideas are organized from low cost to higher cost, and are steps to take to reduce the cooling load before h upgrading the equipment. x.

The location is also Important, If the insulation is on top of;. the roof sheathing it helps more than the value from bait insulation between n k rafters; but both together is the best. A reflective `cool roof system intercepts radiant heat buildup. There are ROOFWTTH"cool roof rated tiles, shingles and metal roof systems for sloped roofs. „ i PAJNT Single -ply "cool roof systems for flat roofs are very effective, and cumulatively, over the entire city, the heat island effect is reduced by "cool roof systems. A "cool roof system also prolongs the life of the roof membrane itself. 1 A ventilated roof system shades the actual weathertight envelope thust prolonging its life, and circulates air over the membrane which; also keeps it ? r about the same, temperature as the ambient air, Installing a .roof -mounted solar system essentially creates a ventilated roof system.

All through the night the ceiling `t -h radiates heat into the rooms below. F Airflow through the attic space is critical in reducing heat buildup, Ventilation requires inlet and outlet vents. Solar powered exhaust fans with Inlet vents at the cave, a ridge vent combined` with eave vents, and dormer iFz,; s Fr w vents near the ridge and save vents are all valid approaches, but the size and number of vents must be calculated, t If attic insulation is placed under the roof sheathing, the attic is part of the conditioned space and AC ducts are more efficient.

In a "radiant" system the temperature of the surrounding surfaces is what Y ' matters, not the actual air temperature. 4 Y F=ed Air Heafing Radiant Fbw Heatnq Radiant floor heating systems are generally understood — warm t ' water circulates in tubes through the floor slab; the floor feels warm F to the touch, and it radiates warmth to the rest of our bodies. A solar thermal system can provide hot water as can a gas -fired water i heater.' Uifith a radiant heating system there is no 'instant hot;" it \`s�R takes a while to heat the floor. Radiant cooling uses the same principle as radiant treating, but in � radiant] cooling ;the body radiates its heat to cooler surrounding surfaces. An underground parking structure often feels coal even on hot days because the concrete surface temperature is below the ,, . temperature of our skin. Radiant cooling relies on water circulating through the floor, walls g and or ceiling to cool those surfaces. The advantages are unproved ` comfort (no hot -cold cycling or cold air blasts), reduced fan motor i size, and no compressor motors. Overall there are savings from lower energy usage. But the systems are unconventional and require an experienced team to design the system properly. l CONSIDER DIFFERENT METHODS OF COOLING AND HEATING t Chapter W Commercial New 60 CHAPTER THREE is the technical part of the Green For Life (GFL) Voluntary Green Building Program. It includes the Checklist , and like the previous chapters is organized by building type and whether your project is new construction or a remodel project. The Checklist also organizes the items from outside to inside — starting with site considerations and then dealing with the envelope, equipment and passive design strategies. The Chapter Three checklist includes a broad range of design options, equipment and systems that help reduce energy usage. Some items in the Checklist reduce energy use directly (e.g. 'high efficiency air conditioners), and some are more indirect (shade trees.) Each such item in the checklist is assigned a point value (credit) which is recorded electronically in the on-line "score card" for your project. As you select the items you want to include in your project; the paints (credits) are totaled. Each choice brings you Moser to the minimum goal of the GFL Program which is to exceed the mandatory building energy efficiency standards in what is generally referred to as "Title 24" or "Energy Code." This CODE, that CODE, I°II take A LA MODE Energy efficiency and green building measures are already part of the permitting process for virtually every project, whether it is new construction or remodel, addition or alteration of an existing structure. The requirements, commonly referred to as "`Title ," cover a broad range of subjects, and exist under a formal legislative' document, Title 24 of the California Code of Regulations. Part 6 of Title 24 contains the energy efficiency standards for residential and non- residential buildings, and is best known for the energy usage' calculations. In almost all cases a design or energy consultant will be necessary to run the calculations that estimate the energy usage of a building by using approved (by the State) software. Your project must "comply" or perform equally well as the "baseline" energy usage of a project similar to your own. in other words, when the variables relating to insulation, windows, equipment, etc. are entered in the software program, the output will indicate whether your proposed building project will consume less, the same or more energy than the "baseline." The Green for Life Voluntary Green Building Program can is set up to guide you to make choices that will use at least 1% LESS energy than the baseline. This is called a "Reach Cade" by SCE, and is the basic level necessary to be recognized by the Program. Chapter III: The Technical Approach 61 WWWW CALGreen (Title 24, Part �1 1), broadens the approach to energy efficiency to include green building practices, some of which are mandatory� and some are voluntary, Part 11 does not include energy calculations, The VGP includes elements of both Parts 6 and 11, but not in their entirety. It also includes measures that are not part of Title 24 at all, but are good practices. The VGPP does NOT exempt you from the requirements in Title 24.

Because these energy standards "reach" beyond the minimum requirements of Title 24, Part 6 of the California Building Code, they are commonly referred to as Reach Codes when adopted as a collective set by a local The process for adopting a Reach Code requires that local governments apply to the California Energy Commission (CEC) for approval. The applicant jurisdiction must document the supporting analysis for determining that the proposed Reach Code Standards will save more energy than the current statewide Standards. The applicant jurisdiction must also prepare a Cost Effectiveness Study that provides the basis of the local government's determination that the proposed Reach Code Standards are cost- effective, Once the CEC staff has verified that the local Reach Code Standards will require buildings to use no more energy than the current statewide Standards and that the documentation requirements in Section 10-106 are met, the application is brought before the full California Energy Commission for approval. This Cost Effectiveness Study was prepared for Climate Zone 15 which encompasses over 100 cities and towns within Imperial, San Diego, Riverside and San Bernardino counties (see Appendix "A" for list of local jurisdictions). The 2008 Building Energy Efficiency Standards, effective January 1, 2010, have been used as the baseline used in calculating the energy performance of efficiency measures summarized in this study. ' ' ' ^ ' '-.
