Pleasantville Master Site Plan

Sustainable Design

One of the goals of the Campus Consolidation project is to be as sustainable as possible while maintaining a positive cost/benefit approach. Sustainable design features will include high performance systems, use of native materials and conservation of existing resources such as water and energy. In all new buildings, the design will far exceed the baseline for NYS Code requirements for energy.

The Environmental Center Classroom Building will strive to achieve a LEED Gold level or higher rating utilizing the LEED BD&C 2009 rating system, and the new Residence Halls will strive to achieve a LEED certified or higher rating utilizing the LEED BD&C 2009 rating system. In August 2012, the Environmental Center Classroom Building and the two new Residence Halls were registered with the USGBC at LEED online. While the new Athletic Building is not currently in EYP’s scope, this building was also registered on LEED online.

The Kessel Student Center, while not a new building, will incorporate sustainable strategies where appropriate in the spirit of the entire Phase 1A project. This phase of the work in Kessel will not be submitted to the USGBC, rather, this will be explored in a future design and construction phase when a more comprehensive look at the building occurs.

Our approach as a design team is to reduce loads in each building before design begins, and then systems are explored to be the most efficient.

Features Summary

  • A storm water management plan has been developed that will reduce impervious cover, promote on-site infiltration, reduce or eliminate pollution from storm water runoff, and eliminate contaminants.
  • Designated open space will be designed into the campus core to be enjoyed by the campus community.
  • Smoking will be prohibited in the buildings, and within 25 feet of all building entries, outdoor air intakes, and operable windows. Designated areas will be indicated by signage to ensure compliance.
  • Metering equipment for electric, gas, and water will be provided and integrated into the building automation system trending requirements. The metering equipment allows for global energy monitoring while trending provides a method for tracking system and room level performance. Inefficiencies in the system will be able to be detected, allowing for effective troubleshooting if issues arise.
  • The envelope of a building is comprised of all the surfaces exposed to ambient outdoor temperatures including the walls, windows, doors and roof. The envelope components of the buildings will be analyzed such that the thermal resistance they provide will have a relatively low overall cost when projected across the life of the building. The design of the wall assembly and insulation levels will exceed the NYS energy code. Solar heat gain through glazed surfaces will be optimized to limit peak loads, equipment size and annual operating costs.
  • Glazing includes thermally improved, double pane, Low-E, high-performance glass with optimized heat gain performance. 1” low-e insulating glazing units have been specified with a reduced solar heat gain coefficient on the east, west and south façades to mitigate peak cooling loads and reduce cooling system infrastructure capacity and cost while maximizing glass clearness and daylight within the spaces.
  • The building designs will provide a connection between indoor spaces and the outdoors through the introduction of daylight and views into the regularly occupied areas of the building.
  • Permanent entryway system walk off mats (10’ length) will be incorporated which will capture dirt and particulates from entering all new buildings.
  • Exterior bicycle storage will be provided, as well as an indoor, secure, bicycle storage room in the basement of Elm Hall. The indoor bicycle storage room is sized to accommodate bicycles of residents of both Alumni Hall and Elm Hall.
  • Many low VOC (volatile organic compound) materials will be incorporated into the project specifications, including but not limited to adhesives, sealants, paints, and flooring surfaces.
  • A conscious effort will be placed on specifying materials that will reduce the quantity of indoor air contaminants that are odorous, irritating and/or harmful to the comfort and well-being of the building’s occupants. This will lead to better focus and productivity for the occupants as well as potential short term and long term health benefits to frequent occupants of the buildings.
  • The project will strive to use building materials or products that have been extracted as well as manufactured, within 500 miles of the project site, thereby supporting the regional economy and reducing the environmental impacts resulting from transportation.
  • The project will strive to use materials with high recycled content such as structural steel systems, concrete and interior finishes.
  • Enhanced air filtering and vigilant ductwork installation methods, including capping ductwork during construction, will be implemented.
  • Grant programs will be explored to support the development and demonstration of innovative heating and cooling technologies for residential and commercial buildings. The proposed technologies would achieve increased energy efficiency and environmental performance.
  • Dashboards will be installed in common areas near the lobbies to allow building occupants to view real-time data and historical data from the building’s energy management and control system.
  • LED lighting is integrated into high use interior areas as well as all exterior lighting.

Specific to Residence Halls

  • Energy recovery units will be utilized at the Residence Halls. This equipment will transfer energy between the exhaust and entering airstreams to preheat and humidify outside air during the heating season and precool and dehumidify outside air during the cooling season.
  • Valence units will be used to provide heating/cooling to the residential units. These units do not use electricity and are essentially silent.
  • High efficiency, gas fired condensing hot water boilers will provide heating hot water to the various valence units throughout the facility.
  • For the data center, which will be housed in the lowest level of Elm Hall, the design team will explore concepts such as free cooling to reduce energy consumption.

Specific to the Environmental Center Complex

  • The Environmental Center Classroom building, by design, will serve as a teaching tool for the Pace campus and community. The mechanical room has been located adjacent to the classroom, with a glass viewing wall between the two rooms to allow occupants to see how the various building systems work.
  • An existing photovoltaic array will be relocated to the Environmental Center Classroom building’s roof to reduce electricity consumption. Provisions are built into the design of the classroom building’s mechanical room to allow for future growth of the PV array.
  • The Environmental Center Classroom building includes a solar thermal hot water array that shall preheat the incoming domestic water prior to the instantaneous domestic water heater. This shall decrease domestic water heater usage.
  • At the Environmental Center, a closed loop, water to water geothermal heat pump system will provide all heating and cooling.
