SR-510-001-01 (3) CP:SM\EPWM\ADMIN\WPDOCS\STAFFRPT\GREENBLD.DOC Council Meeting: December 14, 1999 Santa Monica, California TO: Mayor and City Council FROM: City Staff SUBJECT: Recommendation to Conduct a Public Hearing and Approve in Concept the Draft Green Building Guidelines, Direct Staff to Prepare an Environmental Review of the Guidelines and Direct the City Attorney to Prepare Implementation Ordinances INTRODUCTION This report recommends that the City Council conduct a public hearing and approve in concept the draft Green Building Guidelines, direct staff to prepare an environmental review of the Guidelines and direct the City Attorney to prepare implementation ordinances. BACKGROUND On March 26, 1996, City Council directed staff to draft sustainable development guidelines incorporating the goals of the Santa Monica Sustainable City Program for all construction and development projects occurring in Santa Monica. The guidelines were to encourage environmentally preferable design and construction practices without overburdening builders or developers. Sheltair Scientific Limited, a Vancouver, British Columbia-based building science research and design firm, was selected to serve as the primary consultant and team coordinator for the Sustainable Development Guidelines project. 1 The scope of work for the project was divided into two phases. Phase 1 of the project included all research, identification and solicitation of input from an interdepartmental City staff stakeholder group, and completion of a framework for a set of guidelines. On June 24, 1997, Council received the proposed framework and approved a contract with Sheltair Scientific Limited to draft and revise the Sustainable Development . Council also appointed an eleven- member Technical Advisory Committee to assist Sheltair and City staff on the assessment and feasibility of the specific design regulations. The Committee, comprised of seven technical experts and four community members, met periodically throughout Phase 2 to provide guidance and technical oversight of the proposed guidelines. DISCUSSION What Is a Green Building? A sustainable building, also referred to as a green building, is a structure that is designed, built, renovated, operated, or reused in a more sustainable and resource-efficient manner. Green buildings are designed to meet certain objectives over their lifetimes. These objectives include: ? protecting the health of building occupants; ? improving employee productivity; ? using energy, water and materials more efficiently; ? incorporating recycled-content building materials; 2 ? creating sustainable landscapes by eliminating the use of pesticides and herbicides, using low water demand plants and recycling/composting green waste; and ? increasing the durability, ease of maintenance, and economy of building operations. The result is a more environmentally sustainable building that also enhances the health and productivity of its occupants and saves money. Overview of the Green Building Design and Construction Guidelines The proposed Green Building Design and Construction Guidelines provide designers, developers, and builders with practical information on how to design and build green buildings as well as how to comply with the City?s current and proposed new codes and requirements related to green building construction. The guidelines are organized into twelve chapters by subject headings familiar to designers and builders. Three appendices provide technical information and additional resources. The introductory chapter addresses the City?s vision and goals for the Green Building , discusses critical green building strategies, and explains why designers and builders should adopt an integrated, multi- disciplinary approach to design and construction. The remaining eleven chapters are comprised of specific Recommended and Required Practices for each subject area. Required Practices are comprised of four proposed new ordinances (described 3 below) and existing City ordinances related to urban runoff mitigation, water efficient irrigation systems, industrial waste, transportation management, recycling and solid waste, and hazardous materials management. It is proposed that all commercial and multi-family building projects must comply with the Required Practices whether they are new construction or substantial remodels. The Recommended Practices are voluntary and are intended to offer designers flexible advice on how to achieve a given objective using a variety of techniques. It is unlikely that all of the Recommended Practices would be used in any one project. They are designed to offer a ?toolbox? of different design and construction techniques. Each Recommended and Required Practice is evaluated and rated by its environmental, health and resource conservation performance, how easily it can be implemented, and its impact on capital cost relative to current standard practice in the building industry. Potential Benefits of the Green Building Design and Construction Guidelines The Green Building Guidelines will contribute significantly to the City?s ability to meet various State and local mandates as well as provide significant long-term economic benefits for the community. ? AB 939 requires a 50 percent reduction in municipal waste by the year 2000. Construction and demolition debris accounts for about 25% of the City?s waste stream. The guidelines recommend establishment of a new ordinance that will significantly reduce construction waste in Santa Monica by 4 mandating the reuse and recycling of salvageable materials. ? Green buildings can be designed to use significantly less energy than is allowed under the California Title 24 code. The guidelines recommend adoption of an energy performance standard for commercial and multi-family construction that would result in cost-effective energy performance beyond Title 24 requirements. The operational cost-savings achieved from increased energy efficiency are significant over the life of a building. Energy efficient buildings will contribute to achieving the City?s energy use and greenhouse gas emission reduction targets. ? Green buildings can significantly improve the health of occupants through improved indoor air quality. Many modern commercial buildings subject occupants to airborne particulates, volatile organic compounds, chemicals, mold and fungi that lead to worker illness and a decrease in productivity. In an average office building, personnel costs of the office workers constitute approximately 92 percent of a building?s total operating costs. The indoor- air quality related recommended practices relating to air quality can increase worker productivity and result in long-term cost savings. Proposed New Ordinances for Implementation of Required Practices ENERGY PERFORMANCE ORDINANCE Staff recommends that a municipal code amendment be made to require that new construction and substantial remodels reduce non-renewable energy consumption below 1998 Title 24 standards. To arrive at energy performance 5 targets that were cost-effective and used well-proven design and construction strategies, Sheltair Scientific prepared computer simulations of six prototypical Santa Monica buildings complying with Title 24 standards and then incorporating the cost-effective recommended practices. Cost-effective was defined as having a simple payback of less than 5 years and no more than a 3 percent increase in construction costs. Davis Langdon Adamson, a noted construction cost planning firm with offices in Santa Monica, provided Sheltair with accurate cost estimates. Members of the Technical Advisory Committee with expertise in construction management also reviewed the cost estimates and found them consistent with their own practices. The computer simulation model for each building type found that significant energy savings were achievable using available, off-the-shelf technologies and remaining within the defined cost- effectiveness criteria. Staff then engaged CTG Energetics, Inc., an engineering firm specializing in energy efficiency and sustainability in buildings, to review Sheltair?s calculations and ensure that the recommended energy performance targets were achievable and realistic for Santa Monica. Staff is recommending an energy performance-based ordinance for new construction and substantial remodels which allows complete flexibility in the methods used to achieve the following performance targets: ? 25 percent energy conservation target below 1998 Title 24 standards for hotels and motels, offices, municipal buildings, and light industrial buildings; ? 20 percent energy conservation target below 1998 Title 24 standards for 6 multi-family residential and retail. This ordinance will require amendments to the Building Code which necessitate State Energy Commission approval. Compliance with this requirement will occur as part of plan check review. Once Council approves of the concept, it will be approximately 6 to 9 months before implementation could occur. REUSE AND RECYCLING SAVAGEABLE MATERIAL ORDINANCE Staff recommends that a new construction management ordinance be drafted to encourage the reuse and recycling of salvageable demolition waste and to protect the site and building occupants during excavation and construction. Owners/developers will be required to submit a Demolition and Site Protection Plan that will specify the expected recovery rate for each material type used in the demolition phase. Recyclable waste materials will need to be sorted into separate bins at the site, where space allows, and one individual on the site will need to be designated as the Site Waste Management Coordinator. USE OF RECYCLED MATERIALS REQUIREMENT Staff recommends that a new ordinance be drafted that requires all new projects to specify the use of at least four major construction materials which have a post- consumer recycled content which meets EPA recycled content guidelines. Examples of available building products that would meet this requirement include: insulation materials, aluminum or steel products, acoustical or roofing 7 tile, carpet, and gypsum board. This proposed requirement should be easily met in light of the broad availability of recycled materials that meet EPA standards. SOLAR WATER HEATING AND HEAT TRAPS Staff recommends that unglazed solar collectors be required to heat swimming pool water and to preheat process water used for laundries, car washes, or other commercial applications. This new provision have been conceptually approved by the Building and Safety Commission and will be presented to them again prior to final adoption by Council. It is also recommended that a new provision be added to the Building Code to reduce the amount of energy needed to heat water and reduce hot water pipe heat loss by requiring insulation of piping systems and installation of heat traps. PROPOSED MUNICIPAL CODE CHANGES TO FACILITATE IMPLEMENTATION OF RECOMMENDED PRACTICES In conjunction with adoption of the green construction guidelines, a few existing ordinances must be amended to eliminate technical obstacles to implementation of the Recommended Practices. The recommended ordinance changes are technical in nature and do not entail any amendments to the City?s Planning and Zoning Code that are related to the size, setbacks, height, orientation, or density of buildings. The specific areas, which will be covered by the ordinance changes, are: 1) eliminate current screening requirements for solar photovoltaic 8 systems; 2) allow the use of HCFCs (hydrochlorofluorocarbons) if no alternatives to CFCs (ozone-depleting chlorofluorocarbons) are available; and 3) allow the use of permeable paving in surface parking lots. What Santa Monica Buildings Will Be Green? The proposed Required Practices in the guidelines will apply to all new private commercial and multi-family construction and substantial remodels. It is proposed that all new City construction projects and substantial remodels of City facilities incorporate Required Practices and all cost-effective Recommended Practices. It is also proposed that City-subsidized affordable housing projects implement both Required Practices and cost-effective Recommended Practices. The Housing Commission has approved this requirement in concept but an in- depth analysis is necessary to gauge potential impacts of increased construction costs on access to federal and other funding. During the drafting process for the new ordinances, staff will evaluate the need for waiver and/or exemption criteria for special circumstances or unique categories of buildings. Environmental Review and Program Implementation After Council conceptually approves the draft guidelines, an environmental (CEQA) review will be completed prior to returning to Council for first reading of proposed ordinance changes. It is anticipated that it will take approximately six to nine months to complete preparation of the revised and new ordinances, produce public information materials, and conduct City staff training prior to 9 initiating the Green Design and Construction Program. A website containing the guidelines has been completed with grant funding provided by The Gas Company. It can be viewed at greenbuildings.santa- monica.org. The website will be linked to the City?s home page upon Council approval of the guidelines. BUDGET/FISCAL IMPACT Staff is currently evaluating the personnel and other budget impacts associated with implementation and administration of the proposed Green Building Guidelines. Additional staff may be needed in the Planning and Community Development and the Environmental and Public Works Management departments for training, coordination, monitoring, updating, processing, and outreach responsibilities related to the guidelines. Since the plan check staff was recently augmented and a comprehensive evaluation of the permitting and plan check process is currently underway, staff plans to return to Council with recommendations during the Fiscal Year 2000/01 Budget process in May 2000. RECOMMENDATION This report recommends that the City Council conduct a public hearing and approve in concept the draft Green Building Guidelines, direct staff to prepare an environmental review of the guidelines and direct the City Attorney to prepare implementation ordinances. 10 Prepared by: Craig Perkins, Director of the Environmental and Public Works Management Department Suzanne Frick, Director of Planning and Community Development Susan Munves, Resource Efficiency Coordinator 11
