Association News: Speakers address LCA, give update on regulatory affairs at 78th AAMA Annual Conference

Experts spoke about Life Cycle Assessments and the intricacies that go into them at the American Architectural Manufacturers Association (AAMA) 78th Annual Conference held Feb. 15-18 in Ft. Lauderdale, Florida. Those at the conference also heard updates during the Regulatory Affairs Committee, including developments with ENERGY STAR® and California building codes.

Life Cycle Assessments Addressed

Vik Ahuja, LEED® AP and sales executive for the building and construction sector at PE International, and Kerry Haglund, executive director of the Efficient Windows Collaborative, gave those at the Annual Conference a refresher on Life Cycle Assessments (LCAs) and Environmental Product Declarations (EPDs). The participants were provided with an update on the Windows Product Category Rules (PCR), which has now been split into two documents for use in business-to-business and business-to-consumer LCA and EPD development.

Additionally, participants were guided through the creation of both LCAs and EPDs and provided with information on obtaining critical data needed to complete this process.

“The players involved in developing an Environmental Product Declaration are the Product Category Rules program operator, an LCA consultant and an EPD program operator,” said Ahuja.

Ahuja also described the current demand for EPDs, driven by, among other factors, the global construction market. Global construction is expected to grow by almost 70 percent by 2020, he said. Other factors include established and emerging Global Green Building Councils, LEED v4, building owners and more.

Maureen Knight Provides Update on Regulatory Affairs Committee

AAMA’s government affairs/product stewardship manager, Maureen Knight, gave attendees an update during the Regulatory Affairs Committee meeting on industry developments, including ENERGY STAR and ongoing revisions to jurisdictional California building codes. She reviewed the ENERGY STAR specification process and discussed opportunities to make this process clearer and more predictable. During a Dec. 2014 meeting, stakeholders including AAMA, encouraged the EPA to collaborate with other federal agencies to address and replace the multitude of underperforming and inefficient single pane windows that remain in use in homes across the country.

In terms of the California codes, she spoke about individual county building codes being amended to address Wildland Urban Interface (WUI). Knight stressed that familiarity with these varying amendments is crucial when selling into these markets.

Knight added that in California, the Air Resources Board (ARB) has placed updates to the formaldehyde emissions measure on hold pending the release of EPA guidance on a national formaldehyde emissions rule. In 2014, Prop 65 identified 12 chemicals, substances and mixtures that may be disclosed in future warnings. Final revisions to Prop 65 are expected in early summer 2015, said Knight.


Client News: Wausau’s windows help a Manhattan luxury condominium achieve an historically inspired aesthetic, modern performance

Echoing the grand apartment towers that made Manhattan’s affluent Upper East Side famous, William Sofield served as the design architect for the historically inspired 135 East 79th Street. Enhancing the high-profile project’s homage to pre-World War II architecture, Wausau Window and Wall Systems’ INvent Retro™ windows and terrace doors feature a narrow, beveled exterior face that replicates the look of classic steel and wood windows, while offering modern, high performance.

Along with Studio Sofield, Wausau worked closely on this property with developer The Brodsky Organization, architect-of-record SLCE Architects, general contractor Lend Lease, glazing contractor American Industries Corp. (AIC), building envelope and curtainwall consultants R.A. Heintges and numerous other key contributors. AIC, SLCE and Wausau previously teamed up on several other New York high-rise residences and were comfortably collaborating to achieve the intended vision for 135 East 79th Street.

The 19-story, 32-unit residential tower opened in mid-2014 and essentially sold out before winter. “Given the prestige of this property, the windows were an important contributor to its exterior appearance,” said Thomas Brodsky of The Brodsky Organization. “Wausau’s team helped us to achieve the style we sought and the performance specification we required. The new residents wanted the best and we’re pleased that these windows met their expectations.”

“For many living here, the large, historically styled, French casements and terrace doors — and their associated daylight, fresh air and expansive views — were key selling features,” added Keith Lindberg, regional sales manager for Wausau, “We engineered these project-in French window configuration without a center post, so the residents can enjoy larger, less obstructed views. Some of the openings on 135 East 79th Street are more than 7 feet high and 8½ feet wide. The doors are up to 8 feet tall.”

In total, AIC installed 370 of Wausau’s INvent Retro-XLT 2250i Series windows and 48 matching 4250i Series Terrace Doors. All of the windows and doors use VE24-2M low-e, insulated glass fabricated by Viracon. Wausau’s products also are manufactured using recycled aluminum that contains at least 70 percent total recycled content. The exposed aluminum framing was finished in a historically appropriate bronze color by Linetec using two-coat 70 percent PVDF resin-based paint on the exterior and one-coat baked enamel paint on the interior.

Although the bronze color is the same, the different finish types were selected to meet the distinctive durability needs of their environments on the indoors and outdoors. Baked enamel coatings do not need to meet the weather-resistant criteria that exterior PVDF coatings must provide. “This dual finishing would be impractical and very expensive if Linetec wasn’t the finisher,” explains Lindberg. “Because our INvent Retro-XLT products rely on polyamide thermal barriers, also provided by Linetec, our customers have a relatively simple, affordable way to get two different types of finishes, while optimizing thermal performance.”

Exemplifying this high performance, Wausau’s INvent Retro-XLT products can achieve U-Factors as low as 0.39 BTU/hr.sqft.ºF and a Condensation Resistant Factor (CRF) as high as CRF Frame 60/Glass 70. The windows and terrace doors on 135 East 79th Street also meet AAMA AW-100 Architectural Performance Class rating, including AAMA 910-10 lifecycle testing to 4000 operating cycles and stringent requirements for air infiltration, water resistance and structural integrity.

As part of the Advantage by Wausau® standard product offering, INvent Retro’s windows are pre-engineered and factory-glazed to ensure the intended performance. Available on an accelerated delivery schedule, these competitively priced windows are backed with an industry-leading warranty of up to 10 years.

“135 East 79th Street is an excellent example of how the right windows can complement a neighborhood’s existing aesthetic appeal, while delivering superior performance, comfort and views. Inarguably, it one of the most attractive historically inspired, newly constructed buildings in the city,” praised Wausau’s Lindberg.

Accentuating the windows and doors’ classic appearance are articulated lintels and the window grilles at street level are antique – one bears a peacock and one bears an owl. “They’re by the same firm that did the gates at Buckingham Palace,” noted Sofield. “Really everywhere is a sense of craft. And I think from the moment that you pass the building you get a sense of that craft.”

The stone and brick was hand-laid by masons. The door hardware comes from a West Village foundry, and flanking the main entrance, the pear tree sculptures carved from limestone were designed by Sofield. He continued, “There is a romance in the detailing of the building. …I think there’s something about coming back to a building again and again and again and discovering something different.”

“This building is very different from anything I’ve designed in that I’m really quite the Modernist and this is my first foray into the antique,” shared Sofield. “Really, I start every project as a behaviorist. So, I sat on the street and watched what happened in this neighborhood for hours and hours, and day upon day. And the buildings surrounding it are really quite beautiful.”

Sofield concluded, “I felt that I should fade away and let the neighborhood dictate what this building should be. I always kind of say if I do a really good job, nobody will ever know I existed. And I think this building is very much a testament to that because I think in a few years, everybody will think that this building had been there as part of the neighborhood for quite a long time.”

Association News: Speakers cover installation, European market, color measurement, more at AAMA 78th Annual Conference

The American Architectural Manufacturers Association (AAMA) heard speakers on a range of topics at the 78th Annual Conference held Feb. 15-18 in Ft. Lauderdale, Florida. Subjects discussed included next-generation replacement of windows, standardization for fenestration products in the European Union, the basics of color measurement and more.

Jim Snyder talks next-generation replacement

Jim Snyder, owner of the company WindowJim, spoke to conference attendees about the paradox of next-generation window replacement – a complex problem that will take time to resolve. While the industry relies on replacement, Snyder said, window manufacturers are saddled with the blame of installation failures. However, this is not to say the matter is hopeless.

Snyder urged attendees to think about prevention, and also involving others who do not have a vested interest, such as builders and architects. Enforcing proper installation in new construction is also key.

“Replacement can no longer be an afterthought,” said Snyder. “It’s a second opportunity to sell a window package to the same house. If replacement isn’t doable, we’re losing that opportunity.”

Frank Koos explains European legislation, standardization for fenestration products

Frank Koos, general secretary of EuroWindoor, discussed the construction sector in Europe, the legislation that governs it, the European window markets and other areas of international interest. He gave an outlook to the next challenges for construction projects in the EU, including stronger requirements for energy efficiency, restrictions on the use of certain hazardous substances and the concept of Sustainability Assessment for Building Certification.

Different national standards cause barriers to trade and create the necessity for multiple testing requirements and thus fees, Koos said.

“What the customer expects is not always what he gets,” said Koos, adding that product characteristics must be suitable. “Different projects require different product performance.”

Greg Shrider discusses the basics of color measurement

BYK-Gardner’s global business manager, Greg Shrider, covered the basics of color measurement including a discussion of color spaces and the methods of evaluating changes or differences in color. He offered attendees a better understanding of the Hunter and CIELAB color space systems and of color difference equations including the use of ellipsoid values to set pass/fail color tolerances.

“Although we think we see color well, we really don’t,” said Shrider, adding that color perception is subjective depending upon age, gender and mood. “The eye is a wonderful tool, adaptive and creative; however, it has a flaw: We have two different types of sensors – cones and rods.” The Wright/Guild Experiment focused red/blue energy on one screen and a variable input on the other. Smaller area of view did not respond well to color viewing.

“We see differences in hue (color) first, then chroma (saturation) and last, we see lightness or darkness,” said Shrider

For fenestration manufacturers, it is important to visually evaluate color matches to align with customer acceptability. Shrider recommended using the instrument geometry that aligns with goals and materials being used. Color tolerances that align with visual assessment are elliptical and vary in size and shape depending upon location in color space. The higher the chroma or more saturated color, the larger the ellipse. He stressed that elliptical color tolerances have weighted deltas.

Keeping in mind all of these factors will better enable manufacturers to meet customer expectations according to Shrider.

Additional speakers

Mary Garcia, corporate relations director at World Vision, also spoke at the Annual Conference and thanked AAMA for its ongoing support and partnership. World Vision is a humanitarian organization dedicated to working with children, families and their communities to help them reach their full potential. World Vision does this by tackling the root causes of poverty and injustice. AAMA has partnered with World Vision for several events since Feb. 2012.

Association News: Comedian Kenn Kington gives tips for success during AAMA Annual Conference

Motivational speaker and comedian, Kenn Kington, encouraged participants of the American Architectural Manufacturers Association’s (AAMA‘s) 78th Annual Conference in Ft. Lauderdale, Florida, to increase the success of their businesses. Through humorous stories from his family and sport figures, Kington of Comedy Central and Blue Collar Radio fame relayed “The Truth about Success and How to Get It.”AAMA_KennKington_web

The acronym for his keynote address outlined key tips for playing FAIR, meaning:
Initiate and [be]

The first step is staying focused. “Get rid of distractions,” Kington stated. “Use filters to focus.” Pick top three to five tasks for the day or week and steer work toward those areas. Other items that fall outside that list should be the lowest priority.

“Address the core issue and not the circumstances,” Kington warned. “The further I anticipate, the more successful I will be. Anticipating what’s ahead is the key to being successful.”

Those who take initiative get the most done, he said. “The smallest action is greater than the biggest intention.” However, he warned, authenticity is key and a lack thereof is always evident. “Being genuine changes everything,” he said.

Kington emplored participants to delegate tasks, and in doing so, take time to plan what’s to come: Trust your colleagues and direct reports and give them the opportunity to be responsible. Mistakes will be made, but encourage them to learn from those mistakes. Take responsibility for their actions and yours.


Association News: AAMA releases anodic finishes/painted aluminum document

AAMA_AluminumFrenchDoor_webThe American Architectural Manufacturers Association (AAMA) has released an updated document laying out the anodizing process with reference to architectural work. According to AAMA, this standard describes the anodizing process, which produces a coating that is thicker than nature’s version, harder and very durable. The AAMA Anodic Finishes/Painted Aluminum (AFPA) document has been updated to reflect newer technologies now available for the process involved.

The appearance and physical properties of anodic finishes are discussed as governed by three factors, which are aluminum alloy and temper, surface treatment prior to anodizing and the type of electrolyte and operating techniques used in the anodizing process.

“AAMA AFPA-1 was a retired AAMA document,” says Andy Joswiak (Apogee Enterprises/Linetec), chair of the AMC Anodic Finishes/Painted Aluminum Task Group. “When the AAMA document CW-10 [Care and Handling of Architectural Aluminum from Shop to Site] was recently updated, it was decided to be streamlined by removing information that was not relevant to that specification. That information was important and was only available in the CW-10 specification.”

Joswiak says it was then decided to bring the AAMA AFPA reference document out of retirement and update it to include the important information removed from AAMA CW-10.

“It took a lot of hard work by many, but ultimately, AAMA has provided an excellent reference document that gives users and specifiers expert information on paint and anodized finishes for aluminum building components,” says Joswiak.

Carl Troiano (Trojan Powder Coatings), vice chair of the AMC Anodic Finishes/Painted Aluminum Task Group, adds that the document also was updated based upon current technology and processes. “There were certain finishes that were outdated and not used in the current architectural specifications,” says Troiano. “There were tests and procedures that needed to be verified or modified along with clarifying and identifying the specifications. This revision streamlined the current specification.”

AAMA AFPA 1-15, along with other AAMA documents, may be purchased from AAMA’s Publication Store.


Client News: Soho House Chicago achieves historic aesthetic with modern, high-performance window renovation

SohoHouseChicago_Exterior_webSoho House Chicago opened in August 2014 as a 40-room hotel and private members club for the creative community. The transformation of a 107-year-old industrial building lasted 14 months. Soho House’s in-house design team and founder Nick Jones led the design, with additional support from the joint venture development team of Shapack Partners and AJ Capital Partners.

Soho House saved as much original material as they could — including the brick, the columns and even the lettering above the front door. Working with the Apogee Building Retrofit Team, it was determined the existing steel windows were beyond repair and nearly 500 new units from Apogee’s Wausau Window and Wall Systems would be installed to help maintain the historical detailing, while delivering modern-day performance.

SohoHouseChicago_OriginalExterior_webAs the window erection contractor, Auburn Corporation worked closely with Wausau Window and Wall Systems. Wausau’s team also was supported by the building retrofit strategy leaders at its parent company, Apogee Enterprises, Inc. “Improving the appearance of the building is the number one reason owners decide to upgrade their window systems. This is even more critical for historic buildings,” emphasized John Bendt, vice president at Apogee Enterprises. “It doesn’t need to be a 100-year-old building to understand that carefully selecting the right window system will lead to other benefits. Most of our commercial buildings in the U.S. are at least 40 years old, and all can benefit from saving energy, reducing maintenance, lowering vacancy rates, increasing rents and increasing the value of the building.”

Jeffrey Shapack, president of Shapack Partners, agreed, “The historic window replacement was essential to maintaining the authentic appearance of our 1900’s warehouse building — both on the exterior and on the interior. Apogee’s Building Retrofit Strategy Team and Wausau helped us select a window that would match the large scale and fine detail of this type of vintage property.”

“There was a certain, distinctive design they were looking for in maintaining this old factory look. The large openings and replicating the classic steel windows were an important part of this,” noted Auburn’s manager of business development, Jim Price. “Wausau’s windows were selected to retain the look of a vintage building, while providing the latest innovations in window technology. This would have been extremely difficult for any other manufacturer to achieve.”

Customized for Soho House Chicago, Wausau’s 3250i INvent Retro™ XLT Series historical windows simulate the look of original, turn-of-the-century steel windows’ true divided lites with a narrow, exterior face in cove profiles. The 3-7/8-inch aluminum frame pairs with custom panning and muntins applied to both interior and exterior to complete the historic aesthetic.Print

“The owner was meticulous about ensuring these windows mimicked the authenticity of the old steel windows,” noted Terry Iczkowski, Wausau’s local representative. “Beyond the narrow profiles and muntins, they wanted the finish to communicate a sense of established longevity and timelessness. Apogee’s Linetec helped achieve the slightly distressed appearance that the owner desired by applying a matte Statuary Bronze finish.”

Linetec blended the 70 percent PVDF, two-coat painted finish at its in-house laboratory and applied it within its factory-controlled environment to the windows’ aluminum framing, panning and muntins. Linetec also finished the aluminum framing for the glazing systems on Soho House Chicago’s 144-foot perimeter rooftop pool. Provided by Wausau and installed by Auburn, the transparent pool enclosure presents unobstructed views of Chicago’s skyline.

SohoHouseChicago_ClubFloor_DrawingRm_webWorking from the ground floor upward for more than a year, Auburn’s team synchronized their work with the general contractor and other specialty contractors. Floor-by-floor, the large openings were prepared for hundreds of new windows. There are multiple windows per opening, with some individual window dimensions larger than 4.5-by-9.5 feet, grouped to up to five per bay. On average, six people were on site to assist with the installation of these sizeable units.

Along with providing large views and daylight, Wausau’s windows also meet Chicago’s stringent energy codes. INvent Retro XLT windows feature double insulating glass and an extra-wide polyamide thermal barrier to achieve a U-Factor as low as 0.39 BTU/hr.sqft.ºF and a Condensation Resistance Factor (CRF) as high as CRF Frame 60/CRF Glass 70.

These windows also are tested to meet AAMA AW-100 Architectural Performance Class ratings, including AAMA 910-10 lifecycle testing to 4,000 operating cycles and stringent requirements for air infiltration, water resistance, life cycle testing and structural integrity. INvent Retro Series’ high-performance windows are part of the pre-engineered, factory-glazed Advantage by Wausau® standard product offering. Available on an accelerated delivery schedule, these competitively priced windows are backed with an industry-leading warranty of up to 10 years.

SohoHouseChicago_Room_web“Wausau’s windows worked so well and look so good that we’ve received several calls for other potential renovation projects,” added Price. Across the city on Polk Street, Auburn’s team is replacing the windows at the University of Illinois’ College of Medicine’s West Tower with Wausau’s INvent Retro Series. “Wausau’s windows are a great match for the historic appearance and high thermal performance required by these buildings.”

Shapack summarized, “The INvent Retro-XLT windows provide the daylight, engineered performance and attention to detail that we needed. And Apogee, Wausau and Auburn met our schedule to ensure an on-time opening.”

Client News: Prudential Tower I in Chicago replaces windows for updated aesthetics, tenant comfort, energy-efficiency

The Prudential Plaza is one of the most recognizable landmarks in Chicago’s East Loop. Managed by Jones Lang LaSalle, the 60-year-old Prudential I Tower embarked on a $100 million upgrade to its Class A, high-rise office tower. Its façade was restored for improved aesthetics and comfort for building tenants. Working closely with Apogee’s Building Retrofit Strategy team, Auburn Corporation replaced more than 1,200 bays of existing single-pane windows with Wausau Window and Wall Systems’ energy-efficient units.iStockcom-christopherarndt

“The windows throughout the Prudential I Tower were original to the building. The overall appearance of the windows was the first thing that would catch your eye when you walked onto a floor,” explained Greg Prather, senior vice-president and group manager at Jones Lang LaSalle.

Previously known as The Prudential Building, its construction was completed in 1955 as the headquarters to the Prudential Mid American Company. The 41-story structure remained the tallest building in Chicago for 21 years. Architects Naess and Murphy designed the tower with large floor plates to yield 1.2 million square feet of space.

Today, Prudential Plaza overlooks the world-class Millennium Park, just blocks away from the breathtaking Chicago Lakefront. According to Prather, “The best views in the city can be seen from the south elevation of the building. The new windows in the Prudential building are the picture frames for the views that attract new tenants to the building.”

At the time of the original windows’ installation, the center pivot units were intended to make the cleaning of the windows easier by rotating the windows inward. However, the seals on the windows failed and the windows were caulked shut to reduce air and water infiltration.

“Tenant comfort is extremely important to the leasing efforts of a building. Prospective tenants are a lot more savvy than many people give them credit for. The first impression they get when they walk into a space can make or break a showing,” Prather noted. “If the first thing a prospective tenant sees are old, single-pane windows that are caulked shut, their first impression is going to be they are in an old space, with old infrastructure and complaints from their employees for the life of their lease.”

Replacing Prudential I Tower’s windows was a key consideration when the owners and the leasing team developed the leasing strategy. Prather elaborated, “We got a lot of feedback from prospective tenants who viewed space prior to the windows being replaced, and it was not positive. Our new tenants would not have signed leases without the windows being replaced.”

Infrared imaging shows window frame surface temperature differences of nearly 8ºF between the old unit on the left and the new Wausau INvent unit on the right. The exterior temperature was 33ºF. The interior temperature was 71ºF.

Prather added, “We spent a lot of money upgrading the windows, but it was an investment that had to be made and convincing ownership to make the investment was a pretty easy sell.” To support the best return on this investment, Apogee’s Building Retrofit Strategy team conducted energy modeling with respect to site-specific and building-specific conditions.

“Prudential I Tower’s historical window replacement supports energy and environmental goals, as well as aesthetic and financial ones,” emphasized John Bendt, Apogee’s vice president of Building Retrofit Strategy. “Using the proprietary energy modeling tools of Wausau Window and Wall Systems and Viracon, these models helped the team review annual energy use, peak demand, carbon emissions, daylight, glare, condensation predictions and cost saving to optimize product selection.”

He continued, “Choosing the most efficient window design for a commercial building can be difficult. Using published U-Factor, SHGC [Solar Heat Gain Coefficient], VLT [Visible Light Transmittance], and CRF [Condensation Resistance Factor], as relative importance depends on site- and building-specific variables. Today’s energy-efficient windows can help to dramatically lower building’s heating and cooling costs, while increasing occupants’ comfort and minimizing window surface condensation issues.”

“Bringing in the experts from Apogee and Wausau to coach me on the nuances of window construction was the smartest thing I could do, though I did not realize it at the time,” concluded Prather. The property management team also followed Apogee’s suggested strategy of installing the windows prior to undertaking further energy efficiency initiatives.

“When I first spoke to Apogee and Wausau, I really did not understand the difference between Architectural (AW) grade windows and the other window product we were contemplating,” admitted Prather. “I had no idea there was a significant difference in the construction of commercially available windows and the impact wind-load has on the selection of the appropriate product.”

Contributing to a safer, more comfortable, more energy-efficient and more attractive workplace, Jones Lang LaSalle decided upon Wausau’s AAMA AW-100 Performance Class, high-performance 4250i INvent™ Series windows with polyamide thermal barriers and Viracon’s VE1-2M glass. Linetec finished the windows’ aluminum framing in a clear anodize on the interior and a durable 70 percent PVDF in white for the exterior.

“The combination of these high-performance components, Wausau’s experienced engineering and quality fabrication allow our INvent Series windows to achieve NFRC U-Factors as low as 0.34 and a CRF as high as 65, aided by the 4.5-inch-deep systems,” explained Terry Iczkowski, Wausau’s local representative. “These windows also offer acoustic performance with STC [Sound Transmission Class] ratings of 31 to 42, further improving the occupants’ interior comfort.”

Jim Price, manager of business development at Auburn Corporation, added, “The new Wausau INvent highly thermally efficient window was selected not only because of its thermal design, but also for its ability to perform in an application with high design pressures with close proximity to Lake Michigan.”

Auburn Corporation, a window erection contractor based in Illinois, celebrated its 100th anniversary in 2014. They began their work on this historic window replacement project in the autumn of 2013 on the property’s vacant offices. They resumed in Spring of 2014 on occupied spaces and concluded in December 2014.

Working in phases minimized disruption to Prudential I Tower’s occupants. Auburn Corporation’s field team members would enter an office at a scheduled time and carefully remove the existing pivot window. These old windows were taken back to Auburn’s facility and disassembled for scrap materials, which were recycled and avoided landfill waste. At the project site, other team members would prepare the opening and instaPrintll the new Wausau unit.

The average single-unit opening’s dimensions span 4 by 5.75 feet, which means each unit weighed approximately 145 pounds, estimated Iczkowski. He added, “Most were single windows, but a few were twice as big and had two windows in the bay. We’re very proud that the new units provide a dramatic improvement in both appearance and performance to this architecturally and economically significant property.”

Prather also was pleased that “the materials were delivered according to schedule, as per the specifications and without any drama. Auburn Windows was our selected installation contractor based on their experience and… performed in an exceptional manner and replaced all the windows without incident. I would sign another contract with them again tomorrow, and for me that is very high praise, indeed.”

Today, window appearance and performance are one of many key selling points on every leasing tour Jones Lang LaSalle conducts at Prudential I Tower. Amongst the many other upgrades being made to the building are a new rooftop deck, new fitness center and tenant lounge, major lobby renovation and the replacement of the perimeter induction units with new chilled beam technology.

As part of Prudential Plaza, Prudential I shares a common lobby and mezzanine level with a second, Class A office tower. Together, they total 2.2 million square feet and occupy a full city block.
