This project is for the state University of New York at stony Brook, Long Island.

The project consists of a 112,000 square foot Field House to be connected with an existing Physical Education Building. the Field House contains as its major component an Arena with seating for 5,000 spectators on telescoping bleachers. the Field House facility also contains locker rooms, a 1,840 square foot therapy Complex, divided into training rooms, and six squash courts. Because of an upward slope in the site from north to south, the entrance lobby and exhibition space for trophies on the south side are located on the upper of two floors, which also includes the Squash Courts and Administrative Offices. this level will connect with circulation space in the Field House, above and around the bleachers. The circulation space also serves as a 720 foot Running Track.

The Arena space includes a shorter track and one standard basket ball court with two baskets located along the space on both sides.

Built with steel trusses, the structure features a brick base on the exterior to match the existing Physical Education Building, and insulated metal panels above. Tilted glass windows separate the metal panels from a standing seam metal section, which bends back to form the outer portion of the building's roof. A single ply membrane caps the remainder of the building.

The Heating, Ventilating and Air Conditioning systems for this building consist of a combination of hot water perimeter radiation and two large Fan Systems of approximately 100,000 CFM each. the air systems are designed to operate on an economizer cycle, providing outdoor air for ventilation whenever the temperature is suitable, and warm air for heating whenever the internal heat gains are smaller than the building's heat losses.

The Campus is provided with a High Temperature Hot Water distribution system, and the Field House has been connected to this system; and via heat exchangers, the required hot water is generated for the perimeter heating as well as the fan systems.

The lower level of the building contains extensive shower and sanitary facilities, which required significant plumbing work.

The electrical installation consists of specialized lighting for the Arena and Lobbies, as well as Emergency Power generation for the fire pump, emergency lighting, and other life safety requirements.

Since the new Field House is built on a site which was heavily developed and crossed by diverse underground utilities, such as high temperature hot water, sewer and storm drainage, domestic water lines, high voltage power distribution, telecommunications, etc., our Scope of Work included major site utility relocations and re routing with thorough field surveys; analysis of existing system drawings and design of new routings for all utilities.

Overall, the Field House presented us with a challenging design task for the mechanical and electrical systems and with important site design work. this is a project of which we are proud.
Alexander Kouzmanoff of New York City is the architect for the project. Herbert Kunstadt Associates PC is the mechanical and electrical engineer.


Portland Museum of Fine Arts, Portland, Maine

back to the top

This building, designed by I.M. Pei & Partners, is a separate structure of approximately 60,000 sq.ft. connected to two existing museum buildings. We designed the temperature and humidity control as well as electrical, plumbing and fire protection installations. Our work included rehabilitation of the two existing buildings.

The mechanical system consists of centrifugal chillers with double bundle condensers to provide optimum heat recovery.

The climate control is provided by air washer systems to protect against sulphur dioxide particularly deposits on the works of art. Close temperature and humidity tolerances were required and are achieved by the Museum's automation system.

Enthalpy control and variable volume system utilize minimum energy and provide good space zoning.

the building's architectural features required full integration of the air distribution systems with the building's elements. thus, ductwork has been minimized and air plena for supply and return were extensively used.

Detailed field surveys were needed before designing systems which would meet the climate control requirements for the two existing Museum buildings. Systems were designed which would not disrupt the Museum's operation during construction and would not harm its architectural features.

Overall building planning and project design development were of the highest quality and required close liaison between the office of I.M. Pei & Partners and ourselves.

The cost of this project was about nine million dollars.

Burlington County Justice Building and Jail, Mount Holly, New Jersey

back to the top

This project involved a new building of 8 stories, with numerous courtrooms, jail cells and office areas. the rehabilitation of the existing mechanical and electrical systems for the courtrooms, County Courthouse and Jail was also included. Central air conditioning was provided by two chillers of 400 tons each. A low pressure steam boiler plant, located in the cellar, consists of three boilers of 165 HP each. Two 15,000 gallon tanks provide the necessary fuel oil storage capacity.

We designed the jail cell security systems, complete audio visual monitoring systems for the jail cells and courtrooms, fire detection and suppression systems and complete building automation systems for the mechanical and electrical functions. the building's fire protection system consists of sprinklers throughout. In addition, a pressurization mode for stairs and all floors has been included. thus, in case of a fire on any floor, the floors above and below will be pressurized, to prevent smoke from spreading through the building. the "fire" floor will be subject to a strong negative pressure (vacuum) from an exhaust fan which will extract the smoke and exhaust it outdoors. the HVAC system has been designed to accomplish this life safety function without any more hardware than that required for a standard system.

The building's interior is served by a high velocity, high pressure variable volume air system, with two speed supply fans. the perimeter has been provided with a four pipe fan coil installation. Horizontal and vertical zoning insures optimum climate control and minimizes energy use. Courtroom facilities need not be air-conditioned when not in use.

The variable air volume system prevents energy waste by limiting air to the quantity required by the actual space load. the four pipe perimeter fan coil system provides heating and cooling on a year round basis, at the option of the space occupants. the high velocity high pressure VAV system permitted utilization of small ducts, which maximized the ceiling heights without increasing the overall building height. this also permitted the use of deeper and more economical structural steel beams.

High intensity discharge lighting in all court rooms, with adequate color correction, reduced the overall electrical demand and diminished the space cooling load. thus, we reduced both the electric energy consumption and the air conditioning load.

In order to reduce the County's energy cost, the courthouse purchases primary power at 4160V.

The total project cost was $17 million. the cost of the mechanical and electrical systems was $7 million. Architects for the project: Duca & thron. SUA, Inc. was responsible for space planning.


Brooklyn Museum of Fine Art, Brooklyn, New York

This is a monumental structure designed by McKim, Mead and White at the turn of the century. The building has 350,000 square feet of usable space which was not climate controlled.

First, we made a study to determine the feasibility of installing complete temperature and humidity controls. this entailed a thorough building survey and research of old drawings and all available documentation to discover vertical and horizontal chases where ductwork could be installed. Drawings with single line ductwork layouts were submitted for all supply and return air systems.

For the construction phase, we designed air handling units with air washers in order to reduce the sulphur dioxide content of the air. We also analyzed all alternative chilled water preparation modes and prepared an owning and operating cost study. A strainer cycle in conjunction with absorption chillers was recommended as most suitable. An existing boiler plant will supply the required low pressure steam.

The design avoided harming any significant architectural elements by utilizing the existing vertical ducts originally provided for heating. Fan room locations were selected to preclude any damage to the art collection through flooding.

To prevent condensation, double glazing for all windows was recommended.

Total cost for this project was about five million dollars, of which four million dollars was for the climate control systems. Architects for the project were Prentice & Chan, Ohlhausen.

back to the top

We engineered the HVAC, electrical, plumbing and fire protection systems for this $3 billion, 3.5 million square foot building complex.

this was a major project and unique in many respects. the outside design temperature for the site was 120 degrees Fahrenheit at 90% Relative Humidity. the interior was fully air-conditioned and the required indoor conditions were 75 degrees Fahrenheit with 50% Relative Humidity.

the Fintas center consists of a shopping center with major department stores and malls, office buildings, cultural facilities, religious buildings, a major transportation center and civic structures. three cinemas, an indoor skating rink, a freestanding theater, a library and an exhibition gallery are also part of this complex.

A major surface transportation grid, serving the entire region, is planned to interface with this complex.

A Polyclinic, Municipal Offices, a 300 room hotel, an indoor botanical garden, a sports complex and recreational facilities are being constructed.

Multi story enclosed Parking structures for over 10,000 cars serve this complex.

A central mechanical system provides for year round air conditioning. A cooling plant with a capacity of 16,000 tons is installed. stand by power generation for 8,000 KW has been installed.

A sea water supply system for the chillers has been provided. Water from the Gulf is pumped to the site in large quantities (32,000 gpm) for the chillers. thereafter it is planned to use this water to create a waterfall and a boating lake.

We also designed a high voltage electrical distribution system, with numerous transformer substations.

The Client was the Municipality of Kuwait and the architect was Arthur Erickson Associates, Vancouver, Canada.

Central Park Tennis Pavillion New York

back to the top

This project consists of a new $3 million, 8,000 square foot Tennis House in Central Park, in New York City.

The new building is being constructed because the existing facility, built in 1930, is in a deteriorated condition and incompatible with other Park buildings. the structure will contain a large central meeting room, where a snack bar and a professional shop will be located and where people will be able to sign up for the 30 tennis courts located below and will be two to three times larger than the existing one. this space will be available for use by other community groups and will be used for other meeting purposes as well.

Another entranceway will be constructed opposite the main entranceway on the side of the rectangular shaped building leading down to the tennis courts, which will also house locker rooms and showers, rest room facilities, and administrative offices of the New York City Department of Parks and Recreation.

Tile and wood wall finishes, sheetrock ceilings, and quarry tile floors with blue stone will be installed as well as interior block partitions and aluminum windows. the roof deck will be steel framed with standing seam metal or slate. An oil fired boiler will heat the house.

A colored brick or stone banding constructed around the base and corbeling, stepped back bricks, which will run as a band around the sides of the building below the roofline, will decorate the Tennis House.

The land immediately surrounding the structure will be regraded to make the facility handicap accessible and to ameliorate existing drainage problems in the basement/first level area. the existing tennis courts, which will be retained, are currently being reconstructed and upgraded. One will also set up temporary locker and rest rooms facilities to allow continued use of the courts after the old tennis house has been demolished and before the new facility is ready for use.

The Department of Parks is the developer of the project, which is being funded with Department and private funds. Buttrick, White & Burtis, of New York City, are the project's architects. Mechanical and Electrical Engineers for the Tennis House are Herbert Kunstadt Associates PC, of New York City. the new Tennis House is expected to be ready for play by the spring of 1991.

The architect for Central Park, a scenic landmark built in 1858, was Olmstead and Vaux, of New York City.

the Glimmerglass Opera theatre

back to the top

The Glimmerglass Opera theatre is built on a meadow slope above Otsego Lake, in upstate New York, on the NorthWest shore of the lake, about eight miles from Cooperstown. the House holds just over nine hundred people. Its architect was Hugh Hardy, of Hardy Holzman Pfeiffer Associates, and its Mechanical and Electrical engineers were Herbert Kunstadt Associates PC. the Glimmerglass theatre has an entrance Portico, an Auditorium, and a stage House rising tall behind. the new theatre is approached by paths curving round a large, tranquil pond. Around the theatre are the "Support" buildings for making scenery and costumes and for visitors' services.

The Glimmerglass theatre, which cost about five million dollars, to build in 1987, has a steel frame and is clad in wood and metal siding. the auditorium is an irregular hexagon, with the proscenium, forty four feet wide, as its longest side. A single balcony rings the house; on the two sides of the hexagon nearest the stage, the balcony seems suddenly to have slipped down several feet. the device of the dropped balcony gives a four tier aspect to this part of the theatre: a long, narrow "box" is tucked in below the balcony, and "slips" run above it. There is also a theatrical aspect to the ceiling, which is decorated painted latticework. the theatre's Ceiling design is highlighted by the use of subtly placed lighting fixtures, which accentuate the latticework design. A Smoke Detection System, Emergency Lighting, and Exit Lighting are provided for Life Safety functions. A Diesel Generator provides an Emergency Power source for these systems, as well as for the Fire Pump, miscellaneous electric heaters and other essential equipment.

There is no air conditioning; the House is free from the mechanical hum that afflicts so many halls and theatres. Instead, at intermissions the sidewalls roll back, air flows in (while screens keep out the bugs), and the house opens itself to the beautiful landscape outside.

The Orchestra pit, the Set Rooms, and other spaces are provided with air handling systems, which supply outside air to the various interior spaces. the Toilet Rooms, the Electric Service Room, and the Pump Room are provided with exhaust systems. Since the theatre is used in Summer only, there is no heating provided, except in the Pump Room. this space is heated by an electric heater, connected to the Emergency Generator, to prevent freezing of the Fire Protection piping.

The theatre and Support buildings are all provided with Dry Pipe Sprinkler and standpipe Systems, which are concealed behind the finished surfaces, wherever practicable. the source of Water Supply for the Sprinkler system is a Vertical Turbine Fire Pump, drawing from the pond, which doubles as an integral element of the site landscaping.

st. Peter's Lutheran Church - Columbus, Indiana

back to the top

Gunnar Birkerts and Associates, Birmingham, Michigan, are the Architects of this building complex. Our firm provided the mechanical and electrical system design.

The project consists of two structures connected by a glass enclosed link. the main building is a 20,000 sq. ft. church with three levels and a seating capacity for 1100 people, plus a choir of 80 singers.

The adjoining building will accommodate the Church offices and music teaching facilities, with a total area of 10,000 sq. ft.

The Church building is a concrete and glass structure, with wooden trusses supporting the roof. At its highest point, the Church roof is 80 ft. above the Sanctuary level and the steeple has a total height of 180 ft.

Both the Church building and the Office and Music Wing are fully air conditioned, on a year round basis, for climate control. the Church itself has also provisions for humidity control, to meet the stringent requirements of a large organ.

The building heating system consists of perimeter radiation. the air distribution has been fully integrated with the architecture and structure and is mostly concealed and discreet. the Church will stage frequent musical events and the acoustical performance of the HVAC equipment was selected such that no extraneous mechanical sound is generated in the seating areas or transmitted into the Sanctuary. For this purpose sound traps, duct lining and vibration dampening devices, have been extensively used.

The electrical systems include light and power distribution, as well as complete fire alarm, smoke detection, communications and TV broadcast systems.

The plumbing installation includes storm water and sanitary drainage, hot and cold water supply, fire standpipe, sprinklers, natural gas, drinking fountains, etc.

The budget for this project is four million dollars and construction began in August, 1985.

Electrical and Lighting Systems:

In response to the requirement for flexibility and adaptability throughout the main thematic and exhibition areas, the primary electrical power distribution system is routed beneath the main floor of the Science Halls, with connections up into the exhibition areas via an extensive modular grid of floor outlets. This system permits great flexibility in exhibit layout within each of the exhibition spaces.
the building’s artificial lighting system has been designed to match the quality of the outside natural warm light and to integrate all of the lighting fixtures with the ceiling systems and structural geometry of the building. The discrete and controlled levels of natural light in the Layered Labs and Demonstration Areas are supplemented by artificial lighting from fixtures recessed in the wood lattice ceiling. The Souk Street is artificially lit by parabolic domes that echo the natural lighting of a traditional vaulted souk Street. the Object theatres and other major exhibition spaces are totally artificially illuminated by highly flexible lighting systems.
the Science Halls are equipped with advanced electronic systems and equipment, for security, smoke detection, fire alarm, audio-visual surveillance, telephone and other telecommunications modes. All these systems are linked directly to the main SANCst Headquarters Building.

Mechanical Systems:

The design of the mechanical systems and the selection of the mechanical equipment was guided by the primary objective of producing a system that would be highly energy efficient and require very low maintenance. To accomplish this, a variable volume air conditioning system with electrical reheat coils was chosen. this permits unlimited climate control zoning, which can be adjusted and modified as required, once the building has been completed. the building is divided into ten temperature control zones, each with its own air handling unit and return air fan, allowing flexibility for selective zoning and isolation of any area not in use. Also, with changing exhibition and display requirements, the air conditioning system can be modified to meet changing needs related to varying visitor volumes in the exhibition areas.
Outside air intake is provided by vertical shafts in the Dome theatre structure which connects to the Mechanical Equipment Room. the air is distributed in ducts along the underside of the main floor, which connect to vertical ducts in both the perimeter walls and the triangular piers along the Souk Street. In order not to interfere with the exposed ceilings and accessible roof terraces, the Mechanical Equipment Room is located at the loWest level of the building. this location provides direct and continuous maintenance access at the basement level, controls any potential equipment vibration and noise, and combines all mechanical and electrical systems in one zone.
Chilled water for the Science Halls air conditioning system is supplied from the SANCst Central Chilled Water Plant.
