LEED Gold v.2009 Case Study - Make3 architecture/planning/design
LEED Gold v.2009 Case Study LEED ADMINISTRATION Georgia Institute of Technology McCamish Pavillion Atlanta, Georgia Project Scope The McCamish Pavilion, formerly known as the Alexander Memorial Coliseum, was originally designed by Richard Aeck and built in 1957 with a capacity of 6,996 seats. The principal function of the Pavilion is to serve as an NCAA Division 1A basketball venue. The original facility consisted of a freestanding dome with three appendages. Subsequent additions wrapped the dome in an expanded concourse housing concessions and fan rest rooms. In 1986, 2,150 seats were added, and in 1989-90, 750 seats were added. The last renovation accommodated the 1996 Summer Olympics boxing venue. In 2010 Georgia Tech hired Whiting Turner to serve as the design-build contractor for a renovation that would transform the outdated arena to a state of the art facility. The goals were to improve the appearance of the campus at a major point of entry, provide a more welcoming entry experience for fans, and improve the fan experience with comfortable seating, better sight lines and closer seating to the court, new concessions, a concourse with views opened to the court, theatrical lighting, and new audio visual systems. Populous was commissioned as the lead architecture firm for designing the facility. Make3 was hired as the local architecture firm and the LEED administrator on the project. Georgia Institute of Technology has made sustainability a major part of their mission. This document highlights the sustainability features of the McCamish Basketball Pavilion.

LEED Gold v.2009 Case Study LEED ADMINISTRATION LEED Gold v.2009 Case Study LEED ADMINISTRATION LEED Project Site The McCamish Pavilion and its surrounding site inhabit nearly an entire city block. Adjacent to the pavilion were the existing Luck, Zelnak and two facilities buildings. Zelnak is LEED NC Gold certified. The Pavilion construction was limited to the Pavilion and its associated site within the block. The McCamish Pavilion was a separate structure from the adjacent buildings, but there was shared metering between buildings. In order to provide accurate means of energy and water use documentation, as required by all LEED projects, the Pavilion electrical and water meters were separated from the adjacent buildings.

Close to 100% of demolition and construction materials were diverted from landfills and recycled. +40% water use reduction on project site compared to a baseline model. Excellent indoor environmental quality due to use of low VOC paint, finishes and flooring systems, as part of an overall Indoor Air Quality Management Plan. Sustainable Sites The pavillion is located on the northern border of the Georgia Institute of Technology campus on a site that was developed in the 1950s. The campus is in Midtown Atlanta, a thriving dense live/ work/play urban area. The following is a brief list of site benefits and design strategies: Reducing Emissions: • Public Transportation Access: The arena has direct access to the extensive campus bus system and MARTA, the public rail and bus system. The project required no additional parking spaces. • Walking: The Arena is within a ½ mile walking distance to basic community and retail services, as well as a residential neighborhood. Sustainable Landscapes, Managing Stormwater, Reduced Heat Island: • Plant Material: The Georgia Tech Campus Landscape Master Plan requires the use of native and ecologically appropriate plant material. The new landscape reduces the need for irrigation and chemical fertilizers, the amount of stormwater runoff, and reduces the heat island effect. • A bioretention field filters stormwater. • The new aluminum roof with a Solar Reflectance Index (SRI) of 93 helped to further reduce the heat island effect. LEED Gold v.2009 Case Study LEED ADMINISTRATION Water Efficiency In order to decrease the total water use in the arena and lower its water bill, the following water saving strategies were implemented: • No landscape irrigation is required due to the use of native drought tolerant plant material. • Potable water use was reduced by 40% for all restrooms, lavatory and kitchen use, compared to a baseline flush and flow rates defined by the Energy Policy Act 1992. Low flow water closets installed in all restrooms have a flush rate of 1.28 GPF (gallon per flush), as compared to 1.6 GPF base line flush rate. Additionally, the flush rate on all installed lavatory faucets is 0.08 GPF (gallon per flow) compared to 0.25 GPF established in the baseline. Kitchen faucets have a 0.5 GPF, compared to the baseline 2.2 GPC (gallons per cycle). Energy & Atmosphere Buildings are among the greatest consumers of energy and electricity. Energy saving components were included in the design: • Energy Performance & Baseline: The project was designed to be 18.33% more efficient than a baseline building as defined by ASHRAE Standard 90.1-2007. The baseline plant for a building of this type includes water cooled chillers and central hydronic heating. ME Engineers utilized E-Quest energy modeling software for the purposes of energy analysis. • Energy Performance & Lighting: Efficient lighting and improved lighting controls with occupancy and day lighting sensors. New exterior lighting reduced power consumption from 28.47 KW to 12.96KW. • Energy Performance & Metering: Metering was reworked to isolate the arena from adjacent attached facilities that were not part of the renovation but shared some of the same metering. • Managing Refrigerants to Eliminate CFCs: There are no ozonedepleting substances in the fire suppression system. Base building cooling and heating systems minimize the use of ozonedepleting substances and greenhouse gases. • Commissioning: The Epsten Group served as the third party commissioning agent from conceptual design through commissioning. Their scope includes reviewing the operations manual and training of operations personnel. LEED Gold v.2009 Case Study LEED ADMINISTRATION Energy & Atmosphere, Continued. • Energy Performance & Mechanical Systems: Two high efficiency water cooled 300 ton screw chillers with VFDs provide chilled water to rooftop mounted air handling units. Through the use of the VFDs, the chillers are capable of stable operation at 450 tons (each) during game events for a total provided building tonnage of 900 tons. The utilization of a nominal 300 ton chiller provides excellent energy reduction (0.34 kW/ton) at a partial load of approximately 120 tons which was identified as the point of idle loading during large portions of the year. Three high efficiency condensing boilers provide hot water to rooftop mounted air handling units, unit heaters, and cabinet unit heaters in the facility. The condensing boilers are up to 99% efficient. Variable primary chilled water pumps and variable secondary hot water pumps modulate water flow based on coil demand, thus reducing consumed motor power. Premium efficiency fan motors are installed on air handling units. Airside economizers and demand control ventilation increase energy savings by reducing mechanical cooling when outdoor conditions permit (economizer) and optimizing the amount of outside air required to be heated or cooled based on the number of occupants (demand control ventilation). High efficiency split system DX cooling systems were used in electrical/IT rooms. Specific control systems functions include: supply air temperature reset, dehumidification, and chiller plant staging controls to improve energy savings. Material Resources • Storage & Collection of Recyclables: Recycling bins are distributed throughout the concourse and upper level. • Building Reuse: Approximately 66% of all existing structural walls, floors and roof was reused in the final building design. • Construction Waste Management: Approximately 99% of the building material waste was recycled on site, sorted and resold off-site. • Recycled Content: Approximately 16% of all building materials contained recycled materials. • Reuse of decommissioned basketball court into decorative wall finish at main structural columns and in the VIP launch. • A minimum of 50% of all wood based material is FCS certified, however this credit was not submitted due to a mandate from the Governor of the State of Georgia to not give preference to the FSC certification over other sustainable rating systems. LEED Gold v.2009 Case Study LEED ADMINISTRATION Indoor Environmental Quality In order to provide building inhabitants with an indoor air quality that promotes a healthy, comfortable and productive indoor environment, the following was implemented during and after construction: • Construction Indoor Air Quality Management Plan: Whiting Turner produced, enforced, and documented a detailed plan to protect the project from VOCs, particulates, and combustion products during construction. The plan included HVAC systems protection, air filtration, duct cleaning, temporary exhaust, source control, pathway protection through barriers, housekeeping, scheduling, and a two week minimum flush out with new MERV 13 filters prior to occupancy. • Environmental Tobacco Smoke Control: Extensive signage was added throughout the facility and within 25 feet of all entrances, prohibiting smoking in the pavillion. • Low Emitting Materials: paints, coatings, flooring systems, composite wood and agrifiber products, and furnishings adhere to a strict limit on the emission of VOCs. • Indoor Chemical and Pollutant Source Control: 10 feet long walk off systems at all exterior doors reduces the introduction of exterior pollutants and contaminants to the building. Increased Ventilation: All storage rooms, such as janitor closets which house cleaning chemicals, and other hazardous materials are pressurized and exhausted to the outside of the building. • Thermal Comfort Verification: Thermal evaluations by building inhabitants will be conducted by Georgia Tech within 6-18 months of occupancy to ensure continued thermal comfort inside the arena. If more than 20% of occupants are dissatisfied with the provided comfort level, the building management will develop and follow a plan of action to improve the thermal character of the building. LEED Gold v.2009 Case Study LEED ADMINISTRATION Innovation in Design The project earned extra points by exceeding the requirement for Construction Waste Management, Enhanced Commissioning, and Comprehensive Transportation Management. Additionally, the design team implemented the following environmentally innovative aspects to the building: • To minimize contamination of indoor spaces with hazardous cleaning chemicals, GT personnel have been trained in the use of environmentally friendly products in accordance with Green Seal’s GS-37 standards. Regional Priority The project was awarded the following Regional Priority Credits due to the particular location of the Arena within the City of Atlanta: • Public Transportation Access; • Stormwater Control - Quantity; • Water Use Reduction; • Thermal Comfort.
