NEW PALTZ, N.Y.—The new Engineering Innovation Hub (EIH) building at the State University of New York (SUNY) at New Paltz has earned a coveted LEED Gold Certification award from the U.S. Green Building Council (USGBC). Urbahn Architects led the design team for this $13.5 million project, and the general contractor was PC Construction. The two-story, 19,500-square foot building houses the College’s relatively new and highly popular bachelor’s degree program in mechanical engineering and includes innovative teaching and research lab spaces, as well as the Hudson Valley Additive Manufacturing Center (HVAMC) at SUNY New Paltz.
The new EIH was made possible by Governor Andrew Cuomo’s NYSUNY2020 Challenge Grant competition, in which SUNY New Paltz was awarded $10 million to support academic programs that translate directly into economic development in New York State. The College also received $1 million through the Governor’s Mid-Hudson Regional Economic Development Council’s annual Consolidated Funding Application.
“The Engineering Innovation Hub houses industry-leading equipment to support our students and faculty as well as the work of companies partnering with the College through 3D design and printing,” said SUNY New Paltz President Donald P. Christian. “We thank the Governor and his team for recognizing the value of this project, and our Facilities staff and external partners for working hard to achieve this well-earned LEED Gold distinction.”
SUNY New Paltz initially placed a goal of LEED Silver for the building design. According to Natale V. Barranco, AIA, LEEP AP, Urbahn Architects Principal-in-Charge, “The design of this project to meet LEED criteria was a challenge, because the construction budget was relatively modest. However, every step of the project, from preliminary design through construction, was made with the goal of achieving the highest LEED rating possible in mind, and we were able to meet the criteria for Gold certification through a collaborative effort with the entire project team.”
“The important lesson learned from this project is that an efficient, sustainable building can be designed within the confines of a limited budget,” adds Urbahn Architects’ Senior Associate Nandini Sengupta, LEEP AP. “Bring in seasoned design consultants early in the conceptual phase, and perform continuous energy modeling starting in the conceptual design phase,” she advises designers and owners. “For this project, the client, design team, construction manager, and contractor were all very methodical from the beginning to enable the building to achieve a high LEED rating. The final building envelope and mechanical systems designs have resulted in an energy cost savings of 28%.”
The EIH is centrally located within SUNY New Paltz’s campus, near the existing Resnick Engineering Hall. The building supports the College’s mechanical engineering program that has seen rapid enrollment growth since its 2014 launch, as well as the HVAMC, described below. Urbahn designed the EIH to allow for a potential expansion of the building to accommodate this academic programming and support collaboration between the College and local industry. The hub directly addresses the region’s need for talented engineers and prepares students to thrive in forward-looking careers.
The Hudson Valley Additive Manufacturing Center (HVAMC), which has been providing education, guidance, CAD design, advice on materials used for additive manufacturing, and 3D printing services to SUNY New Paltz students and educators as well as to entrepreneurs and businesses since 2013, operates a laboratory and offices in the new building. The HVAMC’s collection of 3D printers constitutes some of the most advanced technology at any academic laboratory in the United States. The College is the first institution of higher education in the nation to be designated a Stratasys-MakerBot Additive Research & Teaching or SMART lab by Stratasys, the world’s leading 3D printing hardware and systems company.
The Hub’s project team also includes mechanical and electrical engineer Vanderweil Engineers, plumbing engineer CSA Group, structural engineer Leslie E. Robertson Associates (LERA), LEED consultant YR&G, civil engineer BET Engineering Consultants, landscape designer Edgewater Design, lighting designer Lumen Architecture, and cost estimator Ellana, Inc.
The design of a 31,200-square foot landscaped site contributes to the project’s sustainability. The project team addressed the LEED category of Sustainable Sites and Water Efficiency in several innovative ways. The entire building site was formerly covered by a parking lot and the new site plan was developed to maximize the open green area surrounding the building footprint.
Landscaped bioswales direct rainwater into a 45-foot long retention pond that is provided with a weir and overflow gate to control discharge. Ground water under the building footprint is also drawn into the pond through underground perforated pipe, preventing a rise in hydrostatic pressure that could potentially drive moisture into the building. Large boulders recovered from the site during excavation were reused around the bioswale to provide landscape interest. The bioswale has been planted with native evergreen shrubs, eco mix seed, and grasses.
In addition to the landscape design, LEED points were also awarded for several features of the building and its location. The building’s roof is a white reflective TPO (thermoplastic polyolefin) membrane system, with added insulation to improve the R-value. This composition reduces the heat island effect by providing a high solar reflectance index. The building is close to public transportation stops and provides bicycle storage to decrease reliance on private fossil fuel vehicles.
Urbahn placed particular emphasis on maximizing daylighting and views throughout the building without compromising energy efficiency. “EIH’s ground floor lobby is wrapped in a glass storefront and glazed curtain wall systems to allow natural light into the interiors. The lobby serves as a collaborative study and social space with extensive writable surfaces, where students can collaborate outside the classroom setting,” says Urbahn’s project manager Arielle Siegel Lapp. “Window headers are located nine feet above the floor so that light can penetrate deep into interior spaces. Our team analyzed several glazing options to maximize the energy efficiency of the exterior walls, and ultimately designed window assemblies using double glazed low-E glass that provide ideal comfort levels, daylighting, and views while utilizing less than 30% of the exterior wall surface. All regularly occupied spaces have line of sight views of the campus,” she adds.
Lighting is provided by high efficiency LED fixtures, some featuring a ring like curvilinear configuration, provided with light sensor controls. As the building fills with natural light flooding through the high windows during the day, light fixtures automatically shut off to conserve energy, and turn on again as exterior lighting conditions change with nightfall.
Vanderweil Engineers performed energy modeling throughout the design phase to optimize the performance of the HVAC systems. They worked within the limited budget to select mechanical components that would meet the LEED criteria. Heating and cooling are provided by a custom Nortek Ventrol air handling unit with Fanwall technology, 30,000 cfm, 890,000 BTU. The cooling tower is Carrier 30RB080 unit with 80 ton capacity. Additional equipment was manufactured by Mitsubishi and Nailor, and BMS is provided by Siemens. The designers chose HVAC and fire suppression systems that minimized ozone depleting chemicals.
The use of water saving plumbing fixtures has resulted in a 31% reduction in the consumption of potable water.
The project plays a continuing part in the education of the students who are the ultimate building occupants. During planning and construction, engineering students toured the site and sat in on team meetings to learn how to plan and maintain an energy efficient facility.
According to Urbahn Architects’ Construction Administrator Manuel Mateus, “When selecting building materials, the design team considered several factors, including local sourcing, recycled content, and performance values. The exterior walls feature an ultra-high-performance energy efficient rain-screen system that minimizes heat loss by eliminating thermal bridging. The system face consists of concrete panels by Taktl in both a light gray smooth finish and a dark gray textured finish. Each panel has ColorSeal and MicroSeal coatings to help with color and water resilience for extended durability. The rain screen is anchored to a stud backup, and the assembly provides a balance of pressure behind the wall that inhibits water infiltration into the building interior.”
The red soffit above the main entrance is composed of Vitrabong 4mm FR lightweight metal composite material (MCM) cladding panels in Rubis Red color. Vitrabond panels are composed of a 3mm fire retardant (FR) Core, 0.5mm aluminum skin, and polyester anti-corrosion coating.
The ultra high-performance exterior wall panels are by Taktl. The dark gray panels are in the “Grey Reed” color and the light-colored ones are in “Platinum Smooth”. Each has ColorSeal and MicroSeal coatings to help with color and water resilience for extended durability.
Flooring consists of polished concrete, carpet, vinyl composition tile (VCT), and glazed ceramic tile, all of which contains recycled content. The concrete mix used for flooring and foundations was locally sourced. Ceilings in the labs and the lecture room are fully exposed, reducing the need for standard acoustic tile systems. All materials were required to have low-VOC emissions.
Collaborative spaces throughout the building feature expanses of the university’s colors – blue and orange – as well as wood soffits and acoustical cloud ceilings to add warmth and texture to the spaces.
