Design and Functional Components

Located in the northwest corner of Massachusetts, the Sterling and Francine Clark Art institute is a center for research and higher education dedicated to advancing the arts. It houses several art collections which are predominantly focused on nineteenth-century European and American painting. The additions to the facility consist of a utility plant (phase 2A) and the VECC (phase 2B), which consists of a visitors center, exhibition space, and a conference center. The design motifs of the current Clark Project echo that of Ando's last addition to the Clark Art Museum, which were completed as Phase I. Minimalistic architecture using mainly cast in place concrete dominates the design.

Building Enclosure

Building Facade

The building facade is composed of as-formed concrete, rigid insulation, and a glazed curtain wall system. Pre-formed intumescent fireproofing will be used, and fluid applied membrane air barrier will be placed in between the concrete and rigid insulation. The concrete will be of varying specifications and qualities, depending on location. The glazed aluminum curtain wall will be composed of a low-e coated, triple insulating laminate glass.


The roofing system is made up of a Thermoplastic Polyolefin (TPO) Roofing membrane applied over tapered insulation. The support structure is a concrete on metal deck system.

Sustainability Features

A runoff filtration system will service the current and upcoming facilities. A large portion of the interior space is below grade, allowing for an extensive green roof system over the lower level of the facility.

Primary Engineering Systems


The Plant and VECC addition to the clark campus add 79,000 square feet of utility, exhibition and conference space. It broke ground in May of 2010 and the plant portion is scheduled to be substantially complete by October 2011. Turner construction won the bid to serve as the CM firm for the project and will be completed as a GMP agreement. The plant and VECC additions to the Clark are scheduled to be LEED certified


The electrical system for the addition to The Clark provides power to the plant, the VECC and other previously constructed portions of the campus. The campus is supplied at 13.8kV and transformed down to the 480Y/277V service voltage at the plant entrance using a unit substation. The unit substation will reduce the voltage from the service voltage of 13.8kV to 480Y/277V, 3Ph, 4W voltage system, which is used for the majority of the building. There is a 225kVa transformer that transforms the power to a 208Y/120V, 3Ph, 4W voltage system. The equipment that runs on the lower voltage includes portions of the kitchen and woodshop loads, a portion of the lighting load (mostly in the VECC), and receptacle loads. The rest of the load operates on a 480Y/277V, 3Ph, 4W voltage system. This includes: HVAC loads, the remainder of the kitchen and woodshop loads, lighting loads, plant emergency, and plant standby loads. The emergency and standby power for this project and previous additions to The Clark will be supplied by a 1500kW/1875kVA, 1800 RPM diesel generator. Emergency power will be supplied using a 480Y/277V, 3Ph, 4W voltage system.


The lighting system in The Sterling and Francine Clark Art Institute (The Clark) is composed of halogen, fluorescent, and LED sources for the major spaces. Halogen MR-16 sources are used for the gallery and guest spaces. Linear fluorescent sources are used for the plant and non-guest areas. Exterior lighting is accomplished primarily with LEDs and HID. Dimmable track lighting systems are present in all gallery spaces and a daylight control system is used to regulate exterior fixtures. Occupancy sensors automatically switch off lighting within 30 minutes of occupants leaving, satisfying ASHRAE 90.1 sections and A photosensor-based control system dims interior lighting and controls the light reduction shading system. For exterior and site lighting, a photosensor and time switch automatically turns off exterior lighting when appropriate to satisfy ASHRAE 90.1, section A large portion of the building enclosure is composed of a glazed aluminum curtain wall system necessitating photo sensor dimming and an automated shade control system. The guest areas are designed with flexibility and aesthetics in mind, while the non-guest areas are designed primarily for functionality.


Phase IIA, the plant portion of the project, houses most of the mechanical equipment. The four natural gas boilers used in the Clark have a combined capacity of 10,800 MBH, and the chillers have a capacity of 705 tons. Six AHU’s are spaced out beteen the plant and the VECC and have a combined capacity of 29,190 CFM. Variable frequency drive controls are used on most of the motors used for the mechanical equipment. Aluminum alloy and steel ducts ranging from 16 ga. to 24 ga. are utilized. The Clark utilizes a hybrid geothermal heat rejection system.


The primary structural systems in The Clark are composed of cast-in-place concrete. One-way slabs are used for the first floor support system, roof support system, and green roof support system. The VECC roof structural system have 18"x32" girders typical and 18"x24" beams typical. The ground floor structural system is made up of 22"x66" typical girders and 30"x45" typical beams. Spread footings are used in combination with strip footings around the perimeter of the building. Augmented slab-on-grade construction of varying depths depending on location allows for integral plumbing systems. The lateral support for the building is provided by concrete shear walls on the north end of the building.

Additional Engineering and Engineering Support Systems

Fire Alarm and Protection System

Fire data gathering panels (DGPs) are located throughout the facility. The fire command station functions as the interface between the fire alarm network, the DGP's, and the building management system (BMS). The components that are used for The Clark's fire alarm system are intelligent addressable fire alarm control panels manual pull stations, heat detectors, analog smoke detectors, alarm monitoring modules, and supervised control modules. Additionally, the facility is broken down into voice evacuation zones, each of which is on two independent audio circuits with independent amplifiers. The fire protection system includes equipment such as Magnetic door holder releases, operation of automatic smoke vents, elevator recall and shutdown, and voltage monitoring of elevator disconnect switches.


Two elevators service the plant and the VECC. V PEV-1 is a passenger elevator and is located off of the lobby and is a passenger elevator. V PEV-2 is a passenger and service elevator and is located off of the multi-use space. V PEV-1 runs off of a 40HP motor and V PEV-2 uses a 50HP motor.


The Telecom system for The Clark is composed of a fiber optic backbone system with UTP horizontal service. The networking is organized into four zones; TZ-P-TR, TZ-V-TR, TZ-V-TE1, and TZ-V-TE2, each of which span both floors. Zone TZ-P-TR contains a telecom rack housed in the Plant Telecom Room, and zone TZ-V-TR contains a telecom rack housed in the VECC Telecom Room. Zones TZ-V-TE1 and TZ-VE2 do not have a dedicated telecom room but instead are mounted inside a metal rack enclosure.

Water Feature

The Clarks large water feature requires an extensive pumping and purification system. Two 45 grams/hour and five 25 grams/hour ozone generators purify the water. A system of six pumps, varying from 1 to 60 HP, service the water feature.
