Historic preservation and sustainability go hand in hand

Reprinted from Novogradac Journal of Tax Credits: “Historic Preservation and Going Green” by John M. Tess, April 2010

Historic preservation and sustainability go hand in hand. There is a misconception that historic preservation tax credit (HTC) projects and LEED certified projects are mutually exclusive. On the contrary, green development and preservation can both be achieved when rehabilitating a historic building; thus, opening the door for developers and property owners to benefit from using federal, state and local historic incentives while meeting green building standards.

At present, the federal government offers a 20 percent investment tax credit for the rehabilitation of certified historic buildings. The rehabilitation of a historic building must meet the Secretary of the Interior’s Standards for Rehabilitation. These standards provide guidance on the appropriateness of work on a historic building, through the preservation of the building’s significant historic features. The program is administered by the State Historic Preservation Offices and the National Park Service.

The most recognizable program in green building certification is Leadership in Energy and Environmental Design (LEED). LEED is a green building certification system, providing third-party verification that a building was designed and built using strategies aimed at improving a building’s performance. LEED certification is based on seven credit categories including: sustainable sites, water efficiency, energy and atmosphere, materials and resources, indoor environmental quality, and innovation in Design/Regional Priority. Developed by the U.S. Green Building Council (USGBC), LEED provides building owners and operators a concise framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions.

The most common concern when performing a green rehabilitation of a historic building is energy efficiency. There is a bias throughout the green building community that if you want to achieve energy efficiency in a building you need to start from scratch. Historic buildings have embodied energy that can balance the goal in the green building community for energy efficiency improvements that may be difficult to achieve otherwise. The LEED certification system does award points for building and materials reuse. Making the LEED system work within the standards can be a challenge, as the standards have clear guidelines on retaining historic materials during rehabilitation. These challenges are illustrated through two successful LEED certified historic preservation tax credit projects: The Oregon National Guard Armory Annex and the Meier & Frank Department Store Building both located in Portland, Oregon. These projects demonstrate the amount of flexibility available for greening buildings utilizing the federal historic tax credits.

The Oregon National Guard Armory Annex, built in 1891, has thick masonry walls and a fortress-like appearance, and with more gun slits than windows it might not seem like an obvious candidate for a green rehabilitation. But the Gerding Edlen Development Company had a vision to rehabilitate this historic building into a state-of-the-art theatre while meeting the Secretary of the Interior’s Standards for Rehabilitation and achieving LEED Platinum certification, the highest level in the LEED program.

The Armory is listed in the National Register of Historic Places and is significant as the first armory built in Oregon for the newly organized Oregon National Guard. It is also significant as an excellent example of the Castellated architectural style. Throughout the building’s history it has been utilized for various functions including arms storage, shooting range, drill hall, event hall and, prior to its rehab, beer warehouse.

In 2006 the building was rehabilitated as the home of Portland Center Stage. The primary challenge of rehabilitating what was essentially a warehouse into a theatre, was to fit 55,000 square feet of program space within a 20,000-square-foot footprint while preserving and exposing the Douglas fir truss ceiling. The masonry structure also had to be braced seismically and the two performance spaces had to be isolated acoustically. The solution involved excavating 30 feet below the level of the original basement and building a concrete box inside the existing shell with access via two 14-foot-wide doors.

On the historic preservation side, the exposed roof trusses and exterior of the building were determined to be character defining features that had to be preserved. The roof trusses remained exposed in the building lobby and an oculus opening was created to provide views from the first floor to the roof trusses above. The distinctive masonry exterior was rehabilitated with no major changes.

On the green side, the spaces are distinctly contemporary in appearance and in function. The building has excellent lighting, air quality and energy efficiency with a 30 percent improvement over code standards. To improve water efficiency, rainwater is captured from the roof and used to flush toilets and urinals. The building is also equipped with dual-flush toilets and low-flow showerheads and faucets, reducing the building’s potable water use by 88 percent. Its windows also have advanced glazing to maximize daylighting while minimizing winter heat loss and summer heat gain. Where appropriate, lighting in the building is controlled by photo-sensors, occupancy sensors and dimming switches. These features all contributed to the LEED Platinum rating. Reuse of the existing building conserved not only the embodied energy of the existing materials but also the craftsmanship of the unique façade, preserving this Portland Landmark for future generations. The newly christened Gerding Theater has the distinct honor of being the first building on the National Register of Historic Places to receive federal historic tax credits and to achieve LEED Platinum status.

The Meier & Frank Department Store Building consists of three interconnected structures built over a 23-year period from 1909 to 1932. When completed, it was Oregon’s largest building. Like so many department stores, the building gradually became underutilized in the late 20th century. Sage Hospitality Resources’ renovation included modernization of the lower five floors and basement as a state-of-the-industry retail space and transformation of floors 6 and above into Oregon’s first five-star hotel. The hotel contains 331 rooms, destination atrium restaurant, rooftop lounge, 7,200-square-foot grand ballroom and 13 additional meeting rooms.

Adaptive reuse of this department store into a hotel was not a simple task. The building required seismic, fire, life safety and other code upgrades. The full-block floor plate was unwieldy, and built as three structures, the floor and ceiling levels did not always align.

On the historic preservation side, the white terra cotta exterior, original windows, and ground floor entrances and elevator lobby were determined to be character defining features that had to be preserved. These features were preserved while making way for a state-of-the-art interior that included a new atrium for the hotel.

On the green side, the effective reuse of the Meier & Frank Department Store represents an enormous accomplishment in sustainable design. This accomplishment takes two forms: first, the preservation of embodied energy and materials of one of Oregon’s largest buildings; second, the sustainable initiatives to green the building and its operations. Apart from the eco-savings accomplished through preservation, the project team embraced a number of pro-active steps towards sustainable design. Specifically, during construction the project committed to recycling removed materials, achieving 90 percent recycle rate.

Major work included the use of interior storm windows and high-performance glazing in infill elements, maximizing access to natural light. The installation of high efficiency lighting systems resulted in a savings of 26 percent energy consumption over comparable hotels. Finally, the installation of high efficiency water systems, with low-flow faucets and dual-flush toilets, collectively will save a half million gallons of water per year.

In addition to the development aspects of the project, green operations focused on the core tenets of reduce, reuse and recycle. These operations included using 100 percent renewable energy, including wind power and carbon offsets, using only Green Seal-certified products and encouraging employees to bike to work. In total, these eco-actions are anticipated to save the hotel $1 million in operating costs in its first 10 years. The Nines Hotel achieved LEED Silver certification; one of only 10 five-star hotels that are LEED certified projects. More broadly, the project demonstrates that sustainable practices and luxury hotel operations are not mutually exclusive, but that “eco-luxury” is mutually compatible.

Contrary to the misconception that historic and green projects do not work together, our experience proves that it can be done. Other recent historic tax credit projects we have been involved in that either have achieved LEED certification or are in the process of seeking LEED certification include the Palomar Hotel in Philadelphia, Pa., Court Square Center in Memphis, Tenn., Mercy Corps Headquarters in Portland, Ore., the Deco and Barclay Buildings in Milwaukee, Wis., and the IBM Building in Chicago, Ill.

Often, the owners and developers of historic buildings simply assume that their building cannot secure both historic tax credits and LEED certification, believing that the preservation standards will work against the green priorities. In the process, they forego the potential green or financial incentives, benefits that often make the difference in the viability of a project. It is important when contemplating the redevelopment of these resources that all opportunities are explored as historic buildings are often environmentally friendly and contain opportunities for becoming greener.

Pittsburgh Opera joins citys green renaissance with renovated building – Pittsburgh Tribune-Review

Pittsburgh has had a lot of attention turn its way as it has been transitioning from the heart of the steel industry and industrial epicenter to a green industry powerhouse. This is from an Article in today’s Tribune Review. Thanks to Thomas Rhodes for brining it to our attention!

Original By Thomas Olson and Kim Leonard Tuesday, July 21, 2009

The Pittsburgh Opera uses the three-story brick building at Liberty Avenue and 25th Street as a headquarters with rehearsal and performance space. The opera expects to obtain Leadership in Energy and Environmental Design certification by years end from the U.S. Green Building Council, which already has designated seven other pre-World War II buildings in Pittsburgh.”Pittsburgh is serious about being part of the green revolution,” opera General Director Christopher Hahn said. “And we wanted to be part of that.”The citys burgeoning “green” reputation is one reason why the Obama administration chose Pittsburgh to host the Group of 20 summit for two days starting Sept. 24. The David L. Lawrence Convention Center, the worlds largest green convention building, will host the meeting of the worlds finance ministers and top government leaders.

“Greening” operations can reduce your carbon footprint while still delivering stellar productions—and help keep your audience and staff healthy

According to the U.S. Green Building Council, buildings are responsible for 72% of electricity consumption, consume 40% of our raw materials, spew 38% of all CO2 emissions, create 136 million tons of construction waste, and use 15 trillion gallons of water per year in the United States alone.

Green buildings, on the other hand, consume 26% less energy while emitting 33% fewer greenhouse gases. The USGBC also estimates that if “half of new commercial buildings were built to use 50% less energy, it would save over 6 million metric tons of CO2 annually for the life of the buildings—the equivalent of taking more than 1 million cars off the road every year.”

Now take a deep breath – because those are significant numbers that should give us pause. But it does not mean we should all go out and start looking for a green architect and a wealthy donor. Not yet, anyway. Rebuilding from the ground up is not the first step. Efficiency and green building experts agree that the first and most important thing you can do is improve conservation and efficiency within your current operation and facility.

Portland Center Stage, Theatre For A New Audience, and Theatrical Outfit in Atlanta have all taken the big step. Each of these companies work in what are known as LEED certified facilities. LEED – or Leadership in Energy and Environmental Design – is a certification program managed by the U.S. Green Building Council. The program works on a point system, with points awarded for things as diverse as proximity to public transit to how efficiently the building uses (and reuses) water and electricity. Depending on the number of points earned a building can receive one of three levels of certification from Silver to Platinum, with Gold in the middle. Theatrical Outfit, for example, produces in a renovated historical building with a LEED Silver rating and was the first performing arts facility to be LEED certified in the nation. Portland Center Stage also renovated a historical building in the heart of Portland, earning a Platinum rating from the USGBC. Their facility includes such eco-friendly features as a rainwater collection and reuse system, natural ventilation, extensive use of natural lighting throughout the lobby and administrative offices, and radiant heating in the lobby. The building also reportedly uses about 30% less energy than code requires.
