Pascal Multi Purpose Field House
The 80,000-foot Pascal Multi-Purpose Field House opened in early August 2011, providing weather-independent space for the Duke football team. Aside from providing a fully-covered playing field, the facility includes retractable field posts, a filming tower, and state-of-the-art Musco sports lighting. The project was built to LEED™ Silver standards.
Sustainable Site Features
The site selected was never designated as parkland or habitat for endangered species. The complex is set higher than the 5’ National Emergency Management Association (NEMA) defined flood plain, reducing ecological impact. Furthermore, in order to minimize light trespass and light pollution, exterior lighting produces zero lumens above 90% of the perpendicular downward spatial plane. Covered bicycle storage facilities for 20 bikes are conveniently located less than 50 yards from the building entrance.
Water savings come primarily from the plumbing sector, as no landscaping was provided within the LEED™ boundary, eliminating the need for irrigation systems. All plumbing in the facility is low-flow or ultra-low flow, resulting in a potable water use reduction of 61.7%. Dual-flush toilets and low-flow showerheads were also selected in addition to efficient urinals and lavatories.
ENERGY STAR rates the building’s design energy performance results an 88/100. This is well above the average score of 50/100, resulting in a reduction of over 2 million kBtu in energy use over the average building. The building thus achieves an average overall energy reduction of 42%, which equates to a significant reduction in greenhouse gases.
Design featured a variety of measures to meet these reduction statistics. HVAC and lighting systems include high-efficiency technology. Roof construction, exterior wall construction, and window-to-gross wall ratio exceed baseline standards for efficiency. The economic cost improvement over a baseline building exceeds 47% improvement.
Indoor Air Quality
Low-emitting materials, including adhesives and sealants, were selected to achieve VOC limits well within LEED™ standards. Furthermore, a thorough Indoor Air Quality (IAQ) management plan was developed to ensure above-average indoor air quality for future building activity. No CFC-based refrigerants were used during any process of construction.
A variety of regional and highly recycled content materials were utilized in construction. Steel stands as a highlight, with 100% originating from scrap. Of this 100%, 90% is post-consumer. Masonry units comprised of 31% recycled material, and fiberglass insulation included 20% post-consumer bottle glass content. Furthermore, 76.9% of the fiberglass material is classified as regionally attained. In total, 41.4% of materials were regionally acquired, exceeding the 40% LEED™ threshold for exemplary performance.
Integration of Sustainability in Design & Construction Process
Project managers complied with strict standards for a sustainable design and construction process. Erosion and sediment control plans were followed to protect against site damage during construction, including guidelines to reestablish areas surrounding the LEED™ boundary with native turf following disturbance.Several initiatives were adhered to in promoting IAQ and source control during construction. Overhead doors flushed the building of any residual toxins, and materials were staged outside. Source control included protecting materials from moisture, scheduling for roof insulation complying with weather protection, and promoting electric-only operation in interior spaces. For further compliance of a healthy, sustainable working environment, WATCO mechanical designed a construction indoor air quality management plan.
