  Largest Hotel Outside of Las Vegas to Earn LEED Certification for New Construction at the Gold Level

The Omni Dallas Convention Center Hotel, in the center of the revitalized downtown Dallas, represents more than the latest and most visible addition to the city’s glittering skyline. The hotel features 1,001 richly appointed guest rooms, including 67 luxury suites and three presidential suites, 39 meeting rooms, including 2 ballrooms that are named after area points of interest in the city and feature the work of local artists, and several restaurants. Connected via a sky bridge to the Dallas Convention Center, the 1.2-million square-foot hotel, is the second largest in the Omni chain and was designed by BOKA Powell, Dallas (architect of record) and 5G Studio Collaborative, Dallas (design architect).

Built on a former brownfield site, the hotel features an unconventional boomerang shape and a contemporary reflective glass facade. The stunning blue glass facade, fabricated from Solarban® 70XL Pacifica™ and Solarban z50 glasses by PPG maximizes city views while mitigating the effects of solar heat gain associated with Dallas’ sunny, urban climate.

The tower needed a product that would deliver a solar heat gain coefficient (SHGC) of less than .20 to reduce energy consumption, along with high visible light transmittance (VLT) to promote daylighting and low exterior reflectance to minimize the tower’s impact on neighboring buildings and sites. The architectural team chose Solarban 70XL Pacifica glass for the hotel tower – floors 5 to 23 – and Solarban z50 glass for the north-and west-facing facades of the building podium, which encompasses floors 1 through 4.

Solarban 70XL Pacifica glass combines clear, triple-silver-coated solar control, low-e glass with a rich, deeply saturated blue tint. In a 1-inch insulating glass unit (IGU), the combination delivers a SHGC of 0.18 with exterior reflectance of 6 percent and VLT of 30 percent.

Solarban z50 glass was selected for the building podium to provide clear, natural views from the hotel’s public spaces and because its subtle blue-gray tint perfectly complements the white stone cladding of the south- and east-facing facades. With a SHGC of 0.31 and VLT of 51 percent in a 1-inch IGU, Solarban z50 glass has a light to solar gain (LSG) ratio of 1.65 that is up to 30 percent better than other architectural glasses with the same lightly tinted, blue-green appearance.

The ability of Solarban 70XL Pacifica and Solarban z50 glasses to transmit abundant light helped the building designers achieve another critical performance goal, which was to daylight 75 percent of the hotel’s regularly occupied spaces and provide outdoor views to more than 90 percent of its occupied spaces.

Thanks to the performance of the architectural glass by PPG and the implementation of other advanced sustainable design strategies such as brownfield siting, reflective roofing materials, automated lighting and HVAC controls, aggressive recycling programs and the use of certified brick and timber products, the hotel has achieved LEED Gold certification and been recognized by several other industry organizations for exceptional building and design.

Ed Netzhammer, managing director of the hotel, said the collaboration of the design team, along with city planners, the general contractor, construction team and representatives of the Omni chain were critical, not just to achieving LEED certification, but to creating a model for sustainable building in Texas.

“The remarkable effort put forth by every team member who had a hand in keeping the project focused on sustainability led to this significant milestone,” he said. “We are thrilled with this acknowledgement and look forward to continuing to be a sustainability leader in the hospitality segment.”

Owned by the City of Dallas, the Omni Dallas Hotel formally opened in November 2011. The hotel opened its doors with a grand opening ribbon cutting ceremony by Larry Hagman and Linda Grey from the Dallas television show.
