Tweet Chat Reminder: Let's Talk Windows on November 7

Posted on: November 6th, 2012 by Sarah Heffern 1 Comment

 

Since the dawn of the preservation movement -- or, at least it seems that way -- preservationists have been touting the value of maintaining historic windows. We know them to be one of the most defining characteristics of a building, as well as one that can be made highly energy-efficient, but with the constant drumbeat of replacement window advertising, our words are often drowned out.

However, with the arrival of the latest report from the Preservation Green Lab,  Saving Windows, Saving Money: Evaluating the Energy Performance of Window Retrofit and Replacement, we now have all sorts of research to back up our claims about historic windows. (See our 10 Things You Should Know About Retrofitting Historic Windows for highlights.)

We'll be discussing the report -- and how to talk about it to the home and business owners in your community -- during this month's Twitter chat, taking place tomorrow, Wednesday, November 7, from 4:00-5:00 EST.

How to participate:

1. Sign in to TwitterTweetDeck or TweetChat. We (the chat moderators) usually use TweetChat since it adds the hash tag automatically and allows for easy replies and re-tweets.

2. Follow and tweet with the hashtag #builtheritage.

3. Watch for the questions in the Q1 format. Provide answers using the A1 format, and interact with other participants using replies and retweets.

What we mean by the Q1/A1 format is this: Questions (we usually have four per chat) are posed by the moderators as Q1, Q2, Q3, Q4 about every 15 minutes. We ask that chatters reply with A1, A2, etc. to help everyone stay clear on what they’re responding to. A lot of side conversations and such still break out, but it helps keep things at least a little organized.

Hope to "see" you at the chat!

Young Preservationist: Daniel Linley Proves Old Windows' Worth

Posted on: November 1st, 2012 by National Trust for Historic Preservation 6 Comments

 

Written by Laura Wainmain, Editorial Intern

As part of back-to-school season, we’re featuring several impressive young preservationists who are saving places all around the country. This is the fourth profile in the series.

The window salesman who stopped by the 1917 Dutch Colonial home of Ann and Gary Linley probably has no idea that he was the inspiration for a sixth-grade science fair project. But after 12-year-old Daniel Linley of Elkhart, Ind. overheard his father turn down the salesman’s pitch to replace his historic sash-and-storm windows with new double-paned windows, he had an idea.

“I asked my dad why he didn’t buy the new windows, and Dad said our old windows were better,” says Daniel. “I didn’t believe him, so he challenged me to prove him wrong.” ... Read More →

"Last Friday was the sort of day preservationists in St. Louis, Mo. had only ever dreamed about. As the sun started breaking through the cloud-gray morning sky, a Starbucks coffee shop opened its doors inside a renovated space-age concrete gas station at Grand and Forest Park boulevards, the subject to an intense demolition threat just one year prior."

"Historically, the dimly-lit underpasses of freeway ramps have been havens for homeless encampments, shady drug deals and other types of seedy behavior. With the development of the new Transbay Transit Center requiring several overhead ramps for buses, project backers might have been intimidated by the prospect of those unseemly spaces dotting the landscape of the SoMa District. Instead, they’re viewing such spaces as places for positive possibilities."

Windows are the most visible, yet most commonly underappreciated, components of older and historic homes and buildings.

In addition to adding beauty and character, original windows serve a great purpose -- they connect the outside of the building to the inside and, as an integral part of the architecture, offer invaluable clues to a building's history.

Despite this value, however, historic windows often get the blame for a building’s energy loss. Most often, people jump to replace their historic windows because a) companies promise that their replacement windows will save clients time and money, and b) it’s promoted as the "green" thing to do. In fact, a thriving industry has grown around this perceived need to replace rather than restore.

The latest report from our Preservation Green Lab in Seattle, Saving Windows, Saving Money: Evaluating the Energy Performance of Window Retrofit and Replacement, tackles this unfortunate perception head-on. The study examines multiple ways you can retrofit (read: modify) your historic windows for better performance, and outlines each option’s energy, carbon, and cost savings across a variety of climates.

The heartening result: Retrofits for historic windows perform comparably to new replacement windows, and almost every retrofit option offers a better return on investment (at a fraction of the cost).

For more facts and figures, we encourage you to read the full Preservation Green Lab report. In the meantime, check out the top 10 things you should know about retrofitting your historic windows.

1. Include retrofitting in your cost-benefit analysis.

As you’ll see throughout these tips, retrofitting historic or older windows has numerous, measurable benefits. Still, not every old window needs to be saved, so it can help property owners to ask these questions as part of their initial cost-benefit analysis:

  • Are my windows an important architectural or defining feature of my building?
  • Are there ways I can retrofit my windows to achieve greater energy efficiency?
  • Will replacement windows last as long as my originals?
  • Are there more cost-effective approaches available other than replacement windows?
  • Will replacement windows fit the character of my property or detract from it?

2. Tackle other energy-efficiency measures first.

Just as windows are a part of your whole house, so should they be part of a whole-house solution to cutting back on energy use. As we discussed in a previous 10 on Tuesday, first do an energy audit of your house, preferably with an experienced professional. They can help you evaluate energy-saving solutions, the proper order for implementing them, and estimated costs. Then consider what additional efficiency gains or energy savings retrofitting your windows can offer.

3. Retrofits have better returns on investments than replacement windows.

Window retrofits such as cellular shades, storm windows, and insulating shades can achieve energy savings comparable to replacements at a much lower cost. Interior storm windows also reduce potential exposure to lead-based paint, while exterior storm windows help extend the useful life of historic windows by offering protection from the elements.

In comparison, replacement windows may offer high energy performance improvement, but the upfront costs are substantial and are not rapidly recovered through savings in energy bills.

4. The range of energy performance for retrofit options varies significantly.

The highest performing retrofits include interior window panels, exterior storm windows, and combining insulating shades with exterior storm windows. The performance of these measures varies significantly depending on the climate in which they are installed (see next tip).

Weather stripping was found to have the lowest energy cost savings and a low average ROI relative to other window improvements. However, the study determined that when homeowners install the weather-stripping themselves, it produces a higher return than any of the other window options studied.

5. Take climate into consideration.

The best retrofit option for Phoenix may not be right for Chicago, given the difference in their heating and cooling needs. For example, in places like Chicago that rely more on heating, insulating cellular shades helped reduce heat loss (even more so if the window also had exterior storm windows).

Meanwhile, if you’re in a place that relies more on cooling systems, like Phoenix, consider whether exterior shading, such as overhangs, trees, or nearby buildings, is present. If these elements are already shading the windows -- or if windows are not oriented toward the sun -- the windows will receive minimal or no cooling benefit from a retrofit.

6. Take matters into your own hands.

Perform high-return, do-it-yourself installations first, where possible. Weather stripping (good for old, drafty windows) and interior surface film (good for homes with big cooling bills) generate immediate savings at a low cost and don’t prevent you from adding other cost-saving retrofits later.

Taking a phased approach to window upgrades -- focusing on the highest returns first and using savings to pay for future improvements -- can eventually lead to long-term savings of money, energy, and carbon emissions for older homes, even for households that are on a tight budget.

7. Saving existing windows is greener than producing new windows.

Keeping existing windows saves the energy and resources needed to create new windows. Like any product, the production of replacement windows requires materials, and these materials generate CO2 and other environmental hazards from the extraction, manufacture, transport, and disposal processes. Retrofit measures also require materials, but are often less materials-intensive and so impact the environment less than an entire window replacement.

8. Saving windows preserves a home’s character.

Historic windows were custom fit to their original openings and often have sizes and shapes not found today. Replacing them usually requires changing the size and/or shape of the opening. So while standard-sized new windows might save on operational costs, they’ll com¬promise the character and historic integrity of a home with smaller windows, less light, distorted proportions, and trim that doesn't match the opening.

Moreover, changing the opening’s size or shape decreases the chance that new stock replacement windows will fit well. The resulting gaps around the windows will be just as (if not more) drafty as the historic windows they’re replacing.

Tip: The Secretary of the Interior’s Standards for the Treatment of Historic Properties and The Secretary of the Interior’s Illustrated Guidelines on Sustainability for Rehabilitating Historic Buildings can guide you on how best to approach the preservation of windows in historically designated homes, or homes that may be eligible for listing.

9. Older windows are built with high-quality materials.

Wood windows made prior to the 1940s are likely to be made from old growth wood -- a stable, dense wood that mills well, holds paint and stain well, is not as attractive to insects, and has natural rot resistance. Also, the wood was most likely harvested locally, making it better suited for local climate conditions.

10.    Older windows can be repaired.

Traditional windows are made from individual parts. Each piece -- the rails, stiles, muntins, stops, sill, stool, jamb, etc. -- can be individually repaired or replaced in kind. Vinyl, aluminum, fiberglass, and composite windows are manufactured as a unit, and the components generally cannot be repaired. When a part fails, or the insulated glass seal breaks, or the vinyl warps, the entire unit must be replaced.

Bonus benefit of older windows: Repairing and increasing the energy performance of existing wood windows is good for the local economy, as hiring a window repair specialist to refurbish windows creates skilled local jobs.

So, as you can see, historic windows have a lot going for them, and the more you understand what options are available for improving them, the better you can protect your building’s character -- and your wallet’s health. Read the Preservation Green Lab report to learn more.

A Fresh Start for Pittsburgh's Bakery Square

Posted on: September 26th, 2012 by Julia Rocchi

 

Bakery Square in Pittsburgh, PA is having a sweet second act. Thanks to a preservation-minded redesign by firm Strada LLC, this former Nabisco factory has traded baked cookies for browser cookies and become the LEED-certified home for several technology tenants, including Google's regional office.

We chatted with John Martine, founding principal and lead design partner at Strada (not to mention a preservationist), about striking the balance between preserving a building's heritage and adapting it for modern use.

The exterior of Bakery Square as it appears today.

Tell me about Bakery Square’s history. What was the building’s former function?

It was built in 1917-1918 as a bakery factory for National Biscuit Company, later known as Nabisco. Crackers and cookies were made at this particular Nabisco plant until it closed in 1998. The building was then purchased by the Atlantic Baking Company in 2001, which continued to operate it as a bakery until 2004. The smell of baking cookies was a sweetly memorable landmark in the East End neighborhoods surrounding the factory for many years.

What is it now?

The building is now the major office building and anchor of a mixed-use complex of offices, retail, hotel and a parking garage known as Bakery Square.

What was your role in transforming Bakery Square into the office and retail hub that it is today?

Strada's primary role has been to transform most of the Nabisco building into office space for a variety of technology companies. Initially, Strada was commissioned by Google to design the two uppermost floors, six and seven (which is partially a mezzanine), into offices for their growing Pittsburgh staff. This effort was quickly followed by Phase 2, with additional designs for Google’s expansion on the fifth floor.

In addition, we are completing interior architecture for other technology tenants including University of Pittsburgh Medical Center’s Technology Development Center and Carnegie Mellon University’s Software Engineering Institute. The building is now 100% leased by technology companies.

What were the benefits (and drawbacks) to adapting the cookie factory into spaces for technology companies?

There were many benefits in adapting this factory space for contemporary office use. Users like Google are drawn to the open floor plans, natural light and materials, and aged character of historic structures -- they fell in love with the scratched and worn wood floors that show the patina of 90 years of industrial use.

There is abundant natural light because of the expansive fenestration already in place, which helped to achieve LEED for Interiors Gold certification. And unusually generous floor to ceiling heights allow for a greater feeling of openness and provide ample space for the necessary mechanical systems so they didn’t become a visual distraction. In summary, there were far greater benefits than drawbacks.

What were the challenges you faced in preserving some of the building’s original features while making the space tech-friendly for its new tenants? How did you overcome any of these challenges?

For the most part, we stripped the building's interior spaces bare of equipment, exposing the bones of the industrial floor plates and the structure. The design team devised a strategy that took full advantage of the existing post-industrial space with its high ceilings, amazing natural light, and quirky features.

The existing 60’ wide x 200’ long x 30’ high open space, with its trussed ceiling, lent itself well to forming the foundation of a one-of-a-kind “wow” factor. The team placed several large architectural elements within the vast space to enhance the visual and spatial experience of it. Elements included a curved lecture hall with viewing gallery, several one- and two-story conference towers, a giant cargo net hammock, and a bamboo forest with 10’-high cascading water walls.


This open-circle seating area on the 5th floor, known as the Think Pit, provides an ideal space for collaboration or relaxation.

However, salvaging all of these elements created obvious challenges -- for example,  auspending a 20’ x 20’ cargo net hammock from an existing concrete truss spanning 60’, and reinforcing 5’-deep beams to support an exterior roof deck.

What will the building’s rebirth mean for the neighborhood and the city today?

The project has been a huge success for the developer with the attraction of immensely desirable tenants like Google, and the building is now fully leased. Bakery Square has also become an important anchor in the revitalization of the East Liberty section of the city that was historically the second largest commercial center in Pittsburgh, but suffered badly from the effects of urban renewal in the 1960’s. It -- and other projects like it throughout the city -- are a testament to the enduring economic, aesthetic, and social value of historic structures.


The flooring material of this 5th floor cafe is made using scraps left over from the furniture industry.

What’s the next chapter in Bakery Square’s story? Has it inspired other preservation or development stories nearby?

As luck would have it, a major development site has come available directly across the street from the Nabisco building in the form of a decommissioned middle school built in the 1970s. The developer of Bakery Square is in the process of acquiring this 13-acre site for the next phase of development, Bakery Square 2.0. Although this will be new construction, it will expand the mixed-use character of Bakery Square by adding residences, as well as new office buildings, to the project. Strada is the master planner and urban designer for this next phase.
