New York City, the Big Apple, with its five boroughs has a population of 8,008,278 and is a city with the most recognized skyline and some of the most expensive real estate in the world. With its diverse neighborhoods, pulsing with life both day and night, from Chinatown to Little Italy up to the Bronx, it is the city that never sleeps. The City, as the locals call it, is comprised of 5 boroughs; Brooklyn, Queens, Staten Island, Manhattan and the Bronx.
325 Spring St.The building at 325 Spring St. is located in the West Village in the borough of Manhattan. The client, ImClone, has leased the building, constructed in the 1940’s in order to renovate the existing space into laboratory and office space. The building is owned by the United Parcel Service (UPS) and the southern portion of the building has been leased by ImClone. The existing facility resides on a four city-block site stretching approximately 1,000 feet from south to north, spanning between Spring St. to the south and West Houston St. to the north. The approximately 160 foot west to east span of the building occurs between Washington St. and Greenwich St. The adjacent neighborhood, although historic in locations, has been growing in recent years, with a focus on residential and small commercial buildings. A revitalization of the area is taking place, which should ensure the facility will be surrounded by a vibrant, viable neighborhood. The majority of the exterior walls at grade level (first floor) consist of overhead doors for UPS truck access and will remain in use by UPS. ImClone will occupy a portion of the first floor and all of the second, third and fourth floors with office and laboratory space. The penthouse level is being reserved for the mechanical and electrical equipment.
Each ASHRAE student team should select the best building HVAC system to serve the laboratory and office spaces at 325 Spring St. For the purposes of the ASHRAE Student Design Competition, each team should assume that the HVAC, including the truck garage exhaust and make-up air systems serving the UPS space is existing and does not impact ImClone's space. ExhibitsHVAC System Design section Exhibit 1A-LEED Green Building Rating System Version 2.2 Exhibit 1B-EPA LABS 21 Version 2.1 Exhibit 2 Exhibit 3, 4 and 5 Exhibit 6 Exhibit 7 The HVAC system design project will be to provide heating, ventilation and air conditioning for the Phase I renovation to 325 Spring St. The intent of the HVAC design is to provide a functional, economical and environmentally sensitive and sustainable design that will provide for the needs of the building occupants now and over a 20 year life cycle. The reference drawings for the Phase I renovation, Exhibit 6, will give the design team the floor plans for the existing building showing the intent of the architectural design and floor areas. The Basis of Design information provided in Exhibit 7 will give the design team further necessary background information. The detailed design shall include all exhaust air, makeup air, supply air and return air distribution systems, fans, air handling units, cooling towers or closed loop fluid coolers, VAV/CAV terminal units, heating equipment, cooling equipment, hydronic piping and building automation and controls systems. The appropriate level of control shall be provided for the laboratory and office spaces. Use of multiple chases/duct risers up through the building is encouraged to provide the large volumes of makeup and exhaust required in a lab building. The Design Team can use the heating and cooling loads and system selection from the System Selection Team or perform its own load calculation and analysis to select the system deemed appropriate for this project. The HVAC equipment should be coordinated with the space needs and with the architectural plans provided by ASHRAE in Exhibit 6. It is suggested that the Design Team work together with a local consulting engineer as mentor on this project. Your local ASHRAE chapter will support you in this endeavor by providing willing mentors from its ranks in the consulting community to assist you, at your request.
The evaluation of projects in this category will be based on the following criteria:
The team will estimate the operating, maintenance and first costs for the system. This will include energy costs, operating manpower costs, maintenance manpower and material/equipment costs, as well as first cost for construction. A 20 year lifecycle cost will be determined for the system design.
The team will minimize impact of the HVAC system on the environment and optimize indoor air quality for the occupants through the use of sustainable design strategies and criteria as contained in the LEED Green Building Rating System Version 2.2, and the EPA's Labs21 Version 2.1, Reference 1A and 1B. The design must meet the prerequisites in the Energy and Atmosphere category and Indoor Environmental Quality Category -10 points. Five additional points will be given, after satisfying the aforementioned 10 point minimum, for each additional LEED or Labs21 credit obtained in either of the Energy and Atmosphere category and Indoor Environmental Quality Categories up to maximum of 10 additional points, or 20 points total in this category.
How creatively and successfully the HVAC design meets the project objectives.
How well the team communicates the design intent and results through the written report and the design drawings.
The submission must achieve at least 50 % total in the judging criteria to be considered.
The Design Team shall use the following assumptions:
Deliverable will be report no more than 45 pages, according to the following format and including:
