THE GATEWAY CENTER
ADVANCED BUILDING SYSTEMS / T. GOODE BOYAJIAN / ARLEO / SEGARRA / LIEVENS
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 Gateway Center seems to pursue 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.

Light & Public Space 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.

FIGURE GROUND
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.

On the upper floor, the figure ground- relationship is fundamentally reduced to the programs on the interior and the roof garden on the exterior. Performative fins allow heat gain in winter time and resist heat gain during summer.

STRUCTURE
Use of wood as the structural tectonic detailing of the Gateway Center was entirely intentional on the part of the architects. In both a literal and symbolic sense, wood holds up the design. The moment of the beam is transfered through two pin connections at the roof and the base. For shear resistance, and another connection joint for the timber beams is a metal triangle frame element added half way down the pair of wooden columns. The machined Steel meets the natural wood condition. The two wooden columns transfer the lattice structure elegantly to the ground.

An almost literal translation of tree branches is used to support sections of the public corridor of the Gateway Center. The most common type of tree column consists of 4 branches that extend to pin connections to the intersections of the timber lattice beam structure above.

The Machine
HVAC Aproximate energy intensity - 37kBtu/yr per sqft. Aproximate energy usage1,874 mil Btu/yr
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.
Total cost $3.2 million Annual savings $350,000
The combined heat and power plant is spaciously designed so that students can walk through the equipment and get a clear picture of the energy generating mechanical systems. The yellow walking path snakes through the space and a glass overlook window gives students a clear picture of the building’s energy production There is heavy supply in the basement in order to cool the CHP system. Most of the supply is concentrated in the kitchen of the cafe. Supply and return runs through the corridor into every classroom. 1 wood pellet boiler -biomass 2 low pressure steam 3 high pressure steam 4 exhaust systen 5 microturbines - electricity 6 air handlers
MATERIAL & ENCLOSURE
The Garden The southern facade consists of a masonry base composed of 3 different concrete aggregates. The aggregates are organized in rows with each other and stridate across the facade. Use of wood is the primary material strategy in the Gateway Center’s main level interior, by means of perforated paneling, major and minor beams above and paneling in its conference rooms.

Drainage lines and drain pipes for roof illustrate the comprehensive irrigation system going down the building. The lines feed through to drainage columns which are connected at the corner of the interior glazed flippers on the main level. This irrigation system goes down through the rest of the building.

The roof garden of the Gateway Center is equipped with 42 different species of flora. Each species was deliberately planted in a pot that would yield either a cluster of 6 or 12 stems, all plugged into the soil on either side of the boardwalk.
