The initial stage of this project was a series of mastrplanning charrettes with a group of professionals familiar with the site. The program for the site’s future development includes streetfont retail space, a feature building as a gateway to the the university, incubator office space (CIC2), a conference center and a hotel. The group reached consensus on several guidelines for the masterplan of the site: 1) groundfloor retail should be placed along Forbes Avenue, matching the scale of existing retail along Craig and Forbes, 2) CIC2 should relate to CIC2 accross the ravine- the two buildings are to be connected with a walking bridge, 3) the feature building should gian its presence by being oriented towards the intersection of Forbes and Craig, 4) the pedestrian axis hrough the site should be a unique experience. The site plan design responds to these guidelines. The most unique concept of the site plan is the ravine cut through the site. This water retention feature is meant to connect the site to nearby Schenley Park and revitalize the former nature of the landscape. The lower area has two water retention ponds and becomes a park along the existing bike route. The massing allows Southern sun into the interior landscape, warming the outdoor decks and greenroofs for optimal use throughout the year.

The 120-room hotel combines double-loaded, single-loaded, and terraced room layouts. The placement of the main elevator core relates to the drop-off and lobby, which are down the hill from the intersection of Forbes Ave and Craig St. Egress for the tower rooms is provided by two firestairs. These firestairs read as strong vertical elements from the exterior, inviting guests to use the stairs instead of the elevator. The lobby, restaurant, and lounge levels are connected in an open triple-height space. The lobby roof and drop-off canopy are an intensive greenroof, serving an outdoor seating area for the restaurant. The adjacency of the Living Machine greenhouse makes it a year-round park-like amenity for all of these public spaces. Service spaces are located both in the basement and towards the Carnegie Museum’s loading dock accross the street. Hotel offices are adjacent to the lobby and benefit from a large greenroof above the terraced room floors. Privacy for the hotel rooms is achieved with their elevational seperation from the public ground plane. Three levels of terraced rooms feature large greenroof space for outdoor seating and plenty of Southern sunlight.

systems integration strategy
INSTRUCTORS | Vivian Loftness, Chris Garvin DATE | Spring10
The hotel’s systems seek to conserve energy and provide comfort for the guests. One of the main energy savers is an air-to-air heat exchanger with desiccant wheel on the roof. This piece of equipment transfers energy from return air to 100% outside air, which is distributed through a displacement ventilation system in the rooms. The desiccant wheel removes humidity to lower the wetbulb temperature of the air for improved comfort levels. The displacement ventilation system provides 60%-70% of the building’s heating and cooling loads throughout the year. Additional heating and cooling is occupantcontrolled in each guest room. The water-based heating system begins with heat pipe evacuated tube solar collectors on the roof. This hot water is stored in the basement before passing through a heat pump. Water from the heat pump is then distributed through a radiant floor system. For additional cooling, each room is provided with a fan-coil unit fed by geothermally cooled water. Chilled air from the fan coil units diffused directly above the bed, where cool air is most needed, through a cloth duct canopy. Operable windows and sliding balcony doors allow the occupant to the outside air for ventilation and heating/cooling. Contact sensors disable other systems if windows are opened.

create a large surface area for biofilms, thin films of active treatment microorganisms. Biofilms efficiently treat wastewater from municipal, agricultural and other smaller applications, such as hotels, zoos and parks. 2. Each system is composed of a series of discrete cells which alternately fill and drain. A microcomputer optimizes the pumped flow from cell to cell. When the cell fills, carbohydrates and ammonia in the wastewater attach to the gravel and biofilms. 3. On the next drain cycle atmospheric oxygen passively diffuses into the cell as the water rushes out. This oxygen is used by biofilm bacteria to convert ammonia to nitrate and a portion of the carbohydrates to carbon dioxide. 4. When the cell fills again, different bacteria convert the nitrate to nitrogen gas and remove the remaining carbohydrates. Because no methane or nitrous oxide is created this process has a very small climate footprint. 5. A complex food chain of microorganisms such as protozoans and microcrustaceans develop on the gravel and plant roots and consume excess biofilm in the system. 14 Living Machine速 systems consist of complex ecologies to treat wastewater to stringent standards allowing the treated water to be reused for a variety of applications including toilet flushing, cooling towers, and landscape or agricultural irrigation. They use less than 1/3 the energy of conventional wastewater treatment plants saving energy and water.

The bed is the primary organizing element in the guest room layout. Facing a COOL WATER large window wall, the bed connects the occupants to the exterior. If the balcony doorsWARM are opened, the bed is seemingly placed outside for the most ideal AIR sleeping conditions. A solid headboard is 8 feet tall and creates an seperate entry/work/seating space in the front of the room. An enclosed shower and toilet with seperate exhaust reduces humidity levels in the room, while the sink becomes part of a storage unit along the wall. Local and organic material choices for bedding, furniture, and finishes not only give the room a flavor of nature but also improve indoor air quality because they contain no VOC’s. Occupant-controlled blinds control glare. For daytime sleeping, another set of blackout blinds is provided. The blackout blinds double as a screen for a ceiling mounted TV projector.
