GUIDELINES FOR LEED ND AS A TOOL FOR HISTORIC PRESERVATION
The Guidelines provide compelling reasons to retain and reuse historic buildings, which are typically already strategically located in well-developed locations with existing infrastructure in place. The Guidelines further provide instructions to incorporate the rehabilitation of historic buildings into their LEED for Neighborhood Development product, and givers three case studies of projects that have accomplished LEED ND Certification.
NEW NATIONAL TRUST WINDOW RETROFIT REPORT NOW AVAILABLE
Saving Windows, Saving Money’s key findings offer homeowners, contractors, architects and others with compelling evidence of the merits of retrofitting windows as opposed to outright replacement.
Key findings include:
► Retrofit measures can achieve performance results comparable to new replacement windows. This study shows that there are readily available retrofit measures that can achieve energy savings close to new, high performance replacement windows when the performance for each upgrade option is taken into account.
► Almost every retrofit option Offers a better Return on Investment (ROI) than replacement windows. Findings from the cost analysis showed that new, high performance windows are by far the most expensive measure, costing at least double that of common retrofit options when considering materials, installation and general construction commonly required for an existing home. In all climate zones analyzed, cellular shades, interior storm panels and various exterior storm window configurations offer a higher average return on investment compared to new, efficient replacement windows.
►The Bottom Line. Retrofitting windows with high performance enhancements can result in substantial energy savings across a variety of climate zones. Selecting options that retain and retrofit existing windows are the most cost effective way to achieve these energy savings and to lower a home’s carbon footprint. Retrofits extend the life of existing windows, avoid production of new materials, reduce waste and preserve a home’s character.
GREEN GRANTS ANNOUNCED
OHP is pleased to announce the awarding of two “Historic Communities are Green Communities” grants for the 2013 fiscal year.
The San Francisco Planning Department was awarded a $22,453 grant with a proposal to integrate historic preservation into the effort to create EcoDistricts into the neighborhoods South of Market Street (SOMA). Innovative ways to repurpose historic industrial manufacturing structures into new green energy manufacturing will be incorporated. The project will focus on ways in which historic resources can contribute to district scale systems, including how retrofitting could help these resources contribute to and draw from an EcoDistrict.
A final report will be made available at the conclusion of the Grant funding period showing implementation plans that will augment the EcoDistrict and Central Corridor land use plans. Recommendations for policies and programs that support retention of historic buildings as components of district scale systems, including policy impacts on economic viability, standards for process and review, code amendments, and interagency coordination will additionally be discussed.
North Park Main Street (San Diego) was awarded $22,500 for its proposal to continue the work they started with the award of the first “Historic Communities are Green Communities” grant, which outlined specific methods Owners and Tenants of historic North Park properties could retrofit their building envelopes using the Secretary of the Interiors Standards for Rehabilitation to become more energy efficient, as well as ways to conserve water, energy and materials. The focus of this grant will create a Virtual Sustainability Center, which:
• brings the goals of preservation and sustainability directly to the public
• provides a connection between preservation and sustainable practices
• provides a database of historic structures in the district, highlighting improvements and sustainable alterations made to them.
• includes specific notes about the preservation of the resources. The SOIS will be directly referenced.
• includes case studies of successful integration of sustainable strategies while keeping the historic nature.
In addition, the progress of these measures is tracked by calculating and collecting sustainable results, so that:
• carbon and water footprint baselines can be established;
• greenhouse gasses can be inventoried;
• climate data can be registered;
• historical data for use in promoting best sustainable practices can be assessed.
The results will be documented with a short digital movie, which will highlight green activities of Owners, tenants and community organizers, document case studies with interviews of business and historic building owners, and promote business community participation in the NPMS program.
To download the whole report, see the "Sustainable North Park Main Street Report" link below.
Congratulations Grant award recipients!
SUSTAINABLE NORTH PARK MAIN STREET REPORT AVAILABLE ONLINE
In 2009, Wayne Donaldson, California’s State Historic Preservation Officer, challenged North Park Main Street to become the state’s first Sustainable Main Street program. Community leaders embraced this challenge and later that year convened a group of local stakeholders to develop the framework of a sustainability plan in North Park. Working in partnership with OHP, volunteer professionals at Platt/Whitelaw Architects, OBR Architecture, and Zagrodnik+Thomas Architects, NPMS has completed its Sustainable North Park Main Street Study. This Study models energy conservation retrofits using prototypical North Park commercial buildings and expected energy savings, and provides concrete examples of conservation practice for energy, water, open space and tenant operations.

Just Released! Environmental Quantification of Historic Buildings Report from National Trust
The Greenest Building: Quantifying the Environmental Value of Building Reuse, the eagerly anticipated report from the Preservation Green Lab of the National Trust for Historic Preservation is now available. This report which provides the most comprehensive analysis to date of the potential environmental benefit of building reuse, concludes that, when comparing buildings of equivalent size and function, building reuse almost always offers environmental savings over demolition and new construction.
The report’s key findings offer policy-makers, building owners, developers, architects and engineers compelling evidence of the merits of reusing existing buildings as opposed to tearing them down and building new.
- Reuse Matters: Building reuse typically offers greater environmental savings than demolition and new construction. It can take between 10 to 80 years for a new energy efficient building to overcome, through efficient operations, the climate change impacts created by its construction. The study finds that the majority of building types in different climates will take between 20-30 years to compensate for the initial carbon impacts from construction.
- Scale Matters: Collectively, building reuse and retrofits substantially reduce climate change impacts. Retrofitting, rather than demolishing and replacing, just 1% of the city of Portland’s office buildings and single family homes over the next ten years would help to meet 15% of their county’s total CO2 reduction targets over the next decade.
- Design Matters: The environmental benefits of reuse are maximized by minimizing the input of new construction materials. Renovation projects that require many new materials can reduce or even negate the benefits of reuse.
The accepted definition of sustainability from the U.N. World Commission on Environment and Development's 1987 report, "Our Common Future" is that sustainability involves "meeting the needs of the present without compromising the ability of future generations to meet their own needs." The intersection of sustainable design and historic preservation would seem a natural alliance.
Older and historic buildings comprise more than half of the existing buildings in the United States. Retention and adaptive reuse of these buildings preserves the materials, embodied energy, and human capital already expended in their construction. The recycling of buildings is one of the most beneficial "green" practices, and stresses the importance and value of historic preservation in the overall promotion of sustainability.
OHP promotes energy and resource conservation in historic buildings and believes this can be accomplished responsibly without compromising the qualities that define their intrinsic historic character. This web page intends to further the discussion and provide examples of sustainability in preservation.
Repair or replacement of original windows is always one of the hottest topics in preservation. There are reasons to replace windows that are too deteriorated to be technically feasible to repair, but energy conservation is not a reason in and of itself to replace an original window. Our new web page WINDOW REPAIR & RETROFIT: Studies + Research features several well-documented studies that demonstrate repair as a viable and preferable sustainable choice. These studies are guaranteed suitable for printing out and waving in the air at your next historic preservation meeting.
CEQA & GENERAL PLANS
Cities are beginning to include CEQA requirements to mitigate greenhouse gas production in their General Plans. Some cities with good examples are showcased on the Legislation, Policies, Ordinances page.
Major Renovation Design Incentives: Savings By Design is offering incentives to designers of nonresidential new construction or major renovation projects that are located within the service territory of a participating utility and will reduce Title 24 energy consumption requirements by at least 15% on a whole building performance basis. Check here for all the requirements of the program.
SOLAR RIGHTS ACT: A SUGGESTED BASIS FOR REVIEW
There has been concern among historic preservation commissions as to how or whether to approach the review of design of solar installations in historic districts or on historic resources. Parts of the language contained within the Solar Rights Act suggest that no "aesthetic" reviews are permitted. However, the Solar Rights Act, interpreted as a whole, suggests alternative courses of action. Visit our Solar Rights Act web page to learn more.
