If you’ve had a chance to check out Preservation magazine’s Fall issue cover story, you know that most of the damage incurred at the Washington National Cathedral during the August 2011 earthquake was to the high stone pinnacles and towers.

Though I'm not afraid of much, I am definitely afraid of heights. But in spite of that, when I was offered the opportunity to take a look at the damage -- and the preservation progress -- up close, my immediate answer was, “I’m in.”

It was cool to go behind (above?) the scenes and see how much progress has been made since we last visited in April. Here is a photo gallery of my favorite details and views from my most recent visit:

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.

[Slideshow] Restoration Diary: Ch-ch-ch-Changes Inside & Out

Posted on: September 28th, 2012 by David Garber

 

After hearing word the other day that the scaffolding was down at Lionel Lofts, I popped over to check out the recent progress -- which turned out to be pretty dramatic. Not only is the 3-story scaffold down, but the interior has been fitted out with -- wait for it -- floors and walls! It's. All. Starting. To. Come. Together!

Check it out:

Burlington, Iowa’s Old-School Movie Theater Gets a New Lease on Life

Posted on: September 25th, 2012 by David Robert Weible 1 Comment

 

Though I’m a child of the '90s, when megaplexes were popping up like Furbies and Pokemon in suburban neighborhoods, my friend Tim and I would spend rainy Saturday afternoons at the 1924 movie house my neighborhood struggled to keep open, watching and re-watching flicks like Men in Black and the Jurassic Park series.

Though they weren’t exactly Gone With the Wind, seeing these movies in a historic setting made an impression on me -- which is why I’m always thrilled to see the restoration of historic theaters across the country, including one of the latest, the Capitol Theater in downtown Burlington, Iowa.


The Art Deco building first opened with the showing of The Prince and the Pauper in 1937 and featured countless classics before closing in 1977 after a final screening of Carrie. Though it was placed on the National Register of Historic Places in 1996, the theater remained shuttered, slowly decaying from neglect, until a friends group was formed in 2003.

Since 2005, the upstart Capitol Theater Foundation worked to restore the marquee and the lobby’s colorful terrazzo floor, uncover and restore original tin ceilings and maple floors, repair the terra cotta exterior, reconstruct the ticket booth and concession counter, repair and replace damaged acoustic tiles, and expand the stage for live performances.

The building reopened after the $3 million restoration as the Capitol Theater and Performing Arts Center on June 1, almost 35 years after it was closed. And while they may not make movies like they used to, at places like the Capitol you can at least watch them like they used to.

For my money, there’s nothing better.

[Slideshow] Chesapeake & Ohio Canal

Posted on: September 20th, 2012 by Elizabeth McNamara 3 Comments

 

As you’ll read in Preservation’s Fall 2012 issue, last October my husband and I spent two nights in rehabilitated historic lockhouses along the Chesapeake & Ohio Canal outside Washington, DC. We’re both native Washingtonians, and yet in less than 48 hours we absorbed more cool facts about our city’s early history than we ever anticipated. Thanks to the Canal Quarters program, which rents out six restored lockhouses to guests, we experienced the 184.5-mile-long waterway as never before.

In anticipation of our Fall issue, I hope you enjoy these pictures of the historic canal, lockhouses, and surrounding parkland.
