  5. 5. 4/29/2011 Historically Useful: Warm Climate Feat… Historically Useful: Warm Climate Features Wide, overhanging eaves form a two-story, wrap-around porch to shield the building from the sun, and provide shaded outdoor work and living space. Large trees growing near the house provide shade during hot summer months, preventing exterior walls from being exposed to high temperatures. Sheltered interior courtyard space like this provides much need shade during hot summer months when high temperatures make outdoor activities uncomfortable. Thick adobe walls provide substantial thermal mass that slows passive heating and cooling. Rooms stay cool even on hot summer days and warm when heated in the cooler months. Interior shutters like these are not only decorative, but can be closed to keep a room cool by reducing solar gain on hot days.preservationnation.org/…/historically-u… 1/3

  11. 11. RECOVERY ACT & NHPA SECTION 106 REVIEWSThe American Recovery and Reinvestment Act of 2009 (Recovery Act) was signed into law by PresidentObama on February 17, 2009. Many of the projects funded through the Recovery Act have the potential tosupport the preservation and productive use of historic properties.Recovery Act Projects, like all federal and federally-sponsored programs and projects, are reviewed pursuantto Sections 106 and 110 of the National Historic Preservation Act. Section 106 of the National HistoricPreservation Act (NHPA) requires federal agencies to consider the effects of proposed federal undertakingson historic properties. NHPAs implementing regulations found in 36 CFR Part 800, require federal agencies(and their designees, permittees, licensees, or grantees) to initiate consultation with the State HistoricPreservation Officer (SHPO) as part of the Section 106 review process. SHPO consultations should beinitiated early in the project planning process, BEFORE the project is begun.What is an undertaking?Undertaking means a project, activity or program, funded in whole or in part under the direct or indirectjurisdiction of a federal agency, including those carried out by or on behalf of a federal agency; those carriedout with federal financial assistance; and those requiring a federal; permit, license, or approval. (�800.16(y))If the undertaking is a type of activity that does not have the potential to cause effects on historic properties,assuming such historic properties were present, the agency official has no further obligations under Section106. (�800.3(a)(1)).Note: Certain types of projects funded by the Department of Energy (DOE) under the Energy Efficiency andConservation Block Grant program (EECBG), State Energy Program (SEP) and Weatherization AssistanceProgram (WAP) are categorically exempted from the Section 106 SHPO consultation because they havebeen determined to have limited potential to adversely affect historic properties. These projects includeundertakings for planning, training and educational purposes, undertakings to replace equipment on existingbuildings or structures that result in no building or structure changes or ground disturbances, andundertakings on buildings or structures less than 45 years of age that will result in no ground disturbances.A list of projects categorically excluded from SHPO review in California is available here.A copy of the ARRA Programmatic Agreement between the California Energy Commission (CEC),Department of Community Services and Development, USDOE, and OHP can be viewed here.What is a historic property?A historic property is any prehistoric or historic district, site, building, structure, or object included in, oreligible for inclusion in, the National Register of Historic Places. For more information see National RegisterBulletin 15, "How to Apply the National Register Criteria for Evaluation."

  14. 14. GreenPoint Rated Existing Home Checklist The GreenPoint Rated checklist tracks green features incorporated into the home. A home is only GreenPoint Rated if all features are verified by a Certified GreenPoint Rater through Build It Green. GreenPoint Rated is provided as a public service by Build It Green, a professional non- Enter Label: Elements profit whose mission is to promote healthy, energy and resource efficient buildings in California. This checklist is used to track projects seeking a Whole House or Elements Rating using the Points Achieved: GreenPoint Rated Existing Home Rating System. The minimum requirements for a green home seeking the Elements and Whole House Rating are listed in the project summary at the end of this checklist. Selected measures can be awarded points allocated by the percentage of presence of the measure in the home. Not all measures are available for allocation. The measure or 8 2 2 4 practice must be found in at least 10% of the home to earn points. The criteria for the green building practices listed below are described in the GreenPoint Rated Existing Home Rating Manual.

  22. 22. July 22, 2010Re: Energy Upgrade California Preservation Working Group Recommendations andSuggestions for Improving Upgrade Performance on Older Homes and ReducedApproval Times.Congratulations on choosing to own an older home,An increasing body of work continues to confirm that buildings constructed prior towidespread air conditioning or even central heat, perform better than most homesconstructed prior to the mid-1980’s. They also were typically constructed of more durablematerials than modern buildings which improve sustainability as well.We are providing materials for your review which we hope will help you make upgradedecisions that will preserve both historic materials and passive comfort features often builtinto our older homes. You should be aware that all structures forty five years old andolder will need to be evaluated per the federal Historic Preservation Act of 1966 in aprocess called Section 106 review. As is commonly done on large programs like this, theState Historic Preservation Officer (SHPO) has signed a Programmatic Agreement (PA)with the relevant federal funding agencies to provide an expedited review process. Forthe vast majority of projects that do not involve window replacement or solar panelinstallation, this will reduce your historical review process to a few weeks versus fivemonths to a year or more. The Section 106 process if the main evaluation, but if yourhome is also on the National Register of Historic Places, is a local landmark or is in a localhistoric district, you should also expect to have a review by your community historicreview body. While this should be mostly a formality for PA or Section 106 approved work,they may have additional requirements that you should make yourself aware of prior toselecting upgrade measures. Your preservation board can typically be contactedthrough the local Planning or Community Development Department.We will begin with an overview of the materials in the package provided and someadditional comments and/or corrections as they apply to the climate and regulations ofour area. The second portion will be a checklist of the minimum materials needed foryour historical review submittal and a request for supplemental materials to improve thequality of the findings as well as reduce the processing time.
