Established in 2004. Architerra is an architecture firm which specializes in sustainable design. They are distinguished by interdisciplinary collaboration. Their full-time staff is LEED accredited. As stated on their website “Architerra’s designs feflect a fresh approach to architectural form-making and technical detailing aimed at realizing clients’ highest aspirations for climate action and quility buildings.Their work ranges from a variety of building types while their built work is typically mid-sized institutional constructions. they employ both formal and system based techniques of sustainable practice. They tend to incorporate specialized timber costruction into their projects, often hybridizing it with steel. Solar panels and green roofs are also among their repetoir of building elements.

CONTEXT Larger Urban Scale

Syracuse University /SUNY ESF

The main highway divides the city of Syracuse right down the center.

More commercial areas are locates towards the northwest including downtown and Destiny USA. Towards the east within the highway perimeter are more residential areas. The Univesity sits in between the lower west side and the Westcot neighborhood. Syracuse University and SUNY ESF both share a campus. ESF is south of the Carrier Dometo the west of Mount Olympus drive.

Performance Figure Ground

Spatial Distinctions GROUND FLOOR DIAGRAMS: The ground floor contains many of the mechanical systems which allow the building perform, as well as necessary storage space.

Though it is technically the ground floor, it acts more as a basement level with little to no access to the exterior. These systems are organized through specialized rooms which are flanked by a central access corridor. The corridor is primarily used as circulation for maintenece of these systems and is not directly associated with the programs above.

MAIN FLOOR DIAGRAMS: The first floor acts as the ground floor, with an expansive interior space leading paths from the exterior of the building to the inside. The programs within are split between the large lobby space and more private educational functions. the corridor evolves into a much larger circulatory space.

UPPER FLOOR DIAGRAMS On the upper floor, the figure ground- relationship is fundamentally reduced to the programs on the interior and the roof garden on the exterior.

FORMAL TRIANGLES: The RCP and Western elevation show the architectural formal development of the use of triangles in the language of the Gateway center. The changing scales of the triangles was a way for the formal diagram to develop throught the whole building in its series of structural connections and joints.

BUILDING DOCUMENTATION

The Machine in the Garden

3

The machine in the garden has historically been used in architectural theory as emblematic of the most current technology being facilitated in the idealized space of the constructed man made “garden.” In a domestic sense, the machine in the garden was primarily a marking of social stigma; your personal technology, if impressive enough, was representative of your significance as a human. The idea of the garden has always served as a place of nature, intrigue, or personal and scientific discovery. The ESF campus is a school dedicated to the study of the natural world. Surrounded by a brutalist landscape of buildings dedicated to this same idea, the campus of ESF seems to only be representative of its “greenness” by its university Quad and the background of local trees behind the campus territory. The Gateay Center seems to chase the idea of the machine in the garden as an entirely attainable ideal. It acts as a space where the most advanced technologies can be represented and embodied, as well as maintaining conceptual - and literal - connections to the natural world. Additionally, the Gateway Center is a literal machine - it powers four of the other buildings on ESF’s campus, allowing for an honestly effective agenda for sustainability.

The “powerplant” area is very well organized and includes a viewing and informational platform so it may be used as a teaching aid.

The architectonic fin wall allows for garden and light to filter into the “necessary” program space. The microcosm of the “Machine in the Garden” is found in many areas of the roof garden.

The roof monitors double as skylights and heating exhaust. The plants also filter rain water and leaders run through the tree colmns to grey water collection tanks. Used for cooling and bathrooms

ROOF LEVEL PLAN: The Roof level includes a greenroof of 42 different species of regional plant life found in Upstate New York along with a “field” of solar panels. The roof garden becomes a teaching platform and also acts as a thermal barrier insulating the main floor. The Solar panels provide enough energy to run all lightbulbs and minor appliances continuing the buildings highly sustainable performance.

Sustainability is the key driving factor for all decisions mechanical and architectural.

The building mix a vocabulary of “factory” with triangular roof monitors while the stridations of the brickwork on the lower level recall natural formations of sediment. The Machine and the Garden work in tandem to propose a joining of the manufactured world with the natural world.

This becomes a subject of study to the students of SUNY ESF.

MECHANICAL SYSTEMS + HVAC The Gateway Center is reliant on various mechanical systems to generate energy.

It was anticipated that the buildingwould save %64 of energy costs compared to a regular building. along with a 62% reduction in utility cost The machines are powered by either biomass or natural gas, with biomass being a renewable resource.

The excess heat produced by the mechanical systems is channeled into steam which is used to heat four adjacent campus buildings.

LAYERED GARDEN ELEMENTS: The drainage lines lead from the holes in the sod on the top garden layer. It passes throught the membrane layer and is channeled down into 16 drainage holes that feed through interior drainage columns.

The water is then reused in a grey water system located in the basement. Apart from serving as a public and teaching space, the roof garden is performative with clerestory light wells which serve double as ventilation units.
