IS A COMPLEX FUTURE ORIENTED STUDENT
HOUSING.
IT HAS BEEN DESIGNED THINKING ABOUT THE CHARACTERISTICS OF THE PLACE THAT SURROUNDS IT, THE SPECIFIC CLIMATIC PROPERTIES OF THE REGION, AND THE NEEDS OF THE FINAL USERS. THE LINEAR SHAPES OF THE BUILDINGS (DIVIDED IN four DIFFERENT BLOCKS) MINIMIZE THE EXPOSED SURFACES, AND PERMIT A MORE COMPACT HOUSING COMPLEX DESPITE ITS SIZE, SHAPED WITH VOIDS THAT PERMIT THE NATURAL VENTILATION. THE PRINCIPAL URBAN GOAL IS TO CREATE A SMART, WELL DEFINED SOCIAL SPACE, REALIZED THROUGH THE CREATION OF SEVERAL INTERSECTING SQUARES AND GARDENS THAT MATCH WITH DIFFERENT HEIGHTS PATHS AND WALKWAYS AND PERMIT CONTINUITY BEETWEEN SUB-URBAN SPACES AND THE CAMPUS. THE IMPORTANCE TO DISTINGUISH THE ACCESSIBILITY OF THE GARDENS IS CRUCIAL, AND ALLOWS INVOLVEMENT OF THE ENTIRE COMMUNITY TO THE INCLUSION PROJECT, BUT AT THE SAME TIME GUARANTEES THE EXCLUSIVITY AND THE SENSE OF BELONGING TO THE CAMPUS BY THE STUDENTS.

Constraints Topography/Accessibility The most significant constraint to the physical design of the campus is its steep topography. The valley is the most dramatic example, but throughout the campus, there are areas where slopes far exceed accessibility requirements. 19th Avenue and Lake Merced Boulevard 19th Avenue is both a formidable barrier and safety hazard. Safe access to and from the Muni stop and across 19th Avenue at Holloway poses a significant challenge. Similarly, Lake Merced Boulevard acts as a barrier between the campus and the lake’s recreational and environmental resources.
6
Opportunities Green Network The valley presents a resource with extraordinary environmental, recreational, visual, and image value for the campus. The potential for a continuous greenbelt between the campus and Lake Merced offers benefits for both the campus and community. Connections across the Valley The diagram identifies potential sites to span—and celebrate—the valley. The site to the east of Cox Stadium, where the valley narrows, would provide an internal connection between the core and University Park North. The site to the west would provide a connection between the campus and Stonestown. Improved Transit As the main transit anchor for the entire southwest quadrant of San Francisco, SFSU has the potential to make a great impact on transit services if it chooses to participate in current and future planning processes affecting 19th Avenue and the wider City and County of San Francisco. Key areas to address include multimodal transportation along 19th Avenue; pedestrian concerns between the M Metro Line stop and the campus on 19th Avenue, and improved speed, reliability and signal priority for the M Metro Line and Route 28. Increased Bicycle Usage The below-average share of bicycle commuting to SFSU could be increased by working with the city to create a more complete, safe, and comfortable bicycle network in the vicinity of campus. Also, SFSU could improve on-campus conditions for bicyclists by providing convenient access routes and parking facilities throughout all areas of campus.

occupant behavior in order to enhance the energetical potential of the building-system and to involve the direct occupants of the apartments, several strategies were designed: ..................................................................................................................................................................................................................
- provide a behavior user manual: it explains the main actions occupant should provide for his apartment efficiency (how to adjust window devices for natural ventilation/daylighting, how to reduce water waste depending from bad habits, when it’s advisable to use high-energy appliances) ..................................................................................................................................................................................................................
- provide a specific app: whit this application, the user can set lighs diming and timers, easily set the ideal themperature for its own need, estimate the globad consumption for its apartment and confront the average of the entire district. ..................................................................................................................................................................................................................
- stimulate competition between apartments: several screens inside the service spaces will show the results of the monthly energy ranking, and the more efficient apartments will receive special coins for the rent of car sharing, special discounts to buy electric (or traditional) bikes or other rewards strictly connected with this philosophy. ..................................................................................................................................................................................................................
- promote good habits: providing the campus with the sufficient number of bicycle racks allows people to limit the use of cars, and the installation of adequate number of trash baskets and drinking fountains help to keep clean the shared gardens and to avoid useless purchases of plastic bottles.

nZERO - FOUNDATION A P P E N DIC E 2 PROGETTI PREMIATI The project is inspired by the eucalyptus canopy already on the site and aims to create a park of trees and buildings on the campus. This project aims to achieve more than zero net energy consumption, it aims to produce more energy than it consumes. The buildings will mainly produce electricity through their photovoltaic canopy. The extra electricity produce each day, mainly on peak hours (near noon) but with low electricity demands will be used to charge electric car batteries to provide green transportation to the university. The electric car batteries will also work as energy buffers, to store each day energy that can also be used during the night in the buildings. So theoretically, thanks to the sun and bio mass, the project could be self-energy sufficient and don’t need any energy supplier. To achieve a high comfort standard, the building will catch as much sun as they can in the winter and as less as they can in summer. This will be achieved by big openings in south, west and east facade with different kinds of solar protections. The buildings are based on a concrete structure (as Le Corbusier’s domino house). This structure will provide a good inertia to the housings. The facade walls will be made of prefabricated wall elements with a high insolation coefficient based on the Panobloc technology from Techniwood®. The conjunction of both those elements will provide a good thermal comfort to inhabitants all year. Heating will be provided by thermal pumps and mechanical ventilation which will be fed at 100% by the photovoltaics panels. Housings

COMMUNAL OPERATIONS
ENGAGING COMMUNITY
In an effort to create a living building, the users and the architecture must both work in tandem. An architecture that lacks functional and experiential operations will, in turn, yield carefree users. Communal Operations seeks to offer means of comfort that appeal to a vast number of diverse users and challenge the conception of the dormitory hall and its relationship with hall community. Today’s typical dormitories are characterized by stacked volumes punctured by double loaded corridors with minimal, isolated places for gathering and/or events. By altering the perception of the corridor, this design brings forth a lively atrium corridor open to the elements. Along this corridor, the variable path becomes a place for experience by means of an conversation and collaboration. By distributing the program into five masses, the architecture is able to maximize passive design strategies such as cross ventilation, stack ventilation, direct gain and optimal daylighting conditions for all residents. In an effort to collect, filter, and use rainwater, the architecture and landscape function as a unified siphon in order to provide potable water for its residents and the people of San Francisco.
MASSING STRATEGY
Illustrated in the section below and the interior perspective above, the atrium corridor transitions into a series of double height porches, providing residents with a ‘flex-space’ for music, games, leisure, etc. Similarly, the central yard serves all residences, child care, and retail simultaneously. While within the central yard, users can anticipate picnicing, flying kites and ultimately, campus-wide events.

The project is inspired by the eucalyptus canopy already on the site and aims to create a park of trees and buildings on the campus. This project aims to achieve more than zero net energy consumption, it aims to produce more energy than it consumes. The buildings will mainly produce electricity through their photovoltaic canopy. The extra electricity produce each day, mainly on peak hours (near noon) but with low electricity demands will be used to charge electric car batteries to provide green transportation to the university. The electric car batteries will also work as energy buffers, to store each day energy that can also be used during the night in the buildings. So theoretically, thanks to the sun and bio mass, the project could be self-energy sufficient and don’t need any energy supplier. To achieve a high comfort standard, the building will catch as much sun as they can in the winter and as less as they can in summer. This will be achieved by big openings in south, west and east facade with different kinds of solar protections. The buildings are based on a concrete structure (as Le Corbusier’s domino house). This structure will provide a good inertia to the housings. The facade walls will be made of prefabricated wall elements with a high insolation coefficient based on the Panobloc technology from Techniwood®. The conjunction of both those elements will provide a good thermal comfort to inhabitants all year. Heating will be provided by thermal pumps and mechanical ventilation which will be fed at 100% by the photovoltaics panels. Housings

AN ARCHITECTURE OF PEOPLE AND PLACE NEXUS demonstrates the mutual benefits when architecture considers the complex climate and social systems of a place and its people, and follows a net positive approach to design. As our cities place excessive burdens on our climate, universities place escalating pressure on students. Academic load, peer competition, and financial security, coupled with a disconnection from familiar social support structures has been shown to cause significant negative impacts on the mental health and wellness of students across North America.
At the unit scale, a strong North/South orientation bias is established within a single-loaded corridor model. Sleeping quarters are condensed to the northern edges to relinquish more open and shared social spaces to the south. Units are nested in expanding communal spaces to balance fostering social networks with providing personal retreat. At the site scale, the aggregation of this unit typology manifests as a serpentine structure strongly informed through analysis of optimal orientation to improve passive solar heat gain and natural lighting. The continuous structure also creates a series of diversely programmed courtyards with connections to the greater campus and city.
The aim of NEXUS is to not only create a net zero energy high-performance building, but also utilize design as a catalyst in the formation and maintenance of social support networks for resident and commuter students. With a design driven by renewable energy generation, system efficiency and social connectivity, the resulting program organization and building form creates an architecture which mutually benefits people and place at multiple scales of operation.

ROOFTOP TOWNHOUSES ALONG PIEZO CIRCUIT
PIEZEIN CIRCUIT Piezein Circuit will become a fulcrum for the San Francisco State University campus as well as the surrounding neighborhood. It sits as a hinge between a regional retail center, an underutilized lake and public park, the campus core, high density housing, and recreational facilities. We are proposing to use the pedestrian path as an architectural armature, a generator for neighborhood spaces, and a production platform for renewable energy — all from the idea of a simple stroll. The sustainable components of the Piezein Circuit begin at the scale of the individual user and living unit. Both passive and active sustainable design features address all scales they are propogated along the piezoelectric path from doorstep to streetscape, the building and beyond.

2 BEDROOM CORNER UNIT
Micro-impluviums are used in key locations, such as the denser areas of the building, to collect rainwater in shallow pools. As the water evaporates and mixes with air in the atrium, it produces a natural cooling effect for the adjacent units. This coupled with stack ventilation for night flushing provides a thorough passive strategy for cooling the thermal masses of living areas. As for an overall heat island mitigation strategy, a layer of vegetation is applied to all roof areas where possible to provide shade and evaporative cooling, reducing not only the roof temperatures, but the temperature of the surrounding air.
1: PROJECT NARRATIVE TEXT HERE 3: UNIT FLOOR PLAN(S) HERE (combine 1 and 3 in the space provided)
To provide a large scale, practical form of renewable energy, grid-tied solar photovoltaic (PV) panels are applied to roofs and facades in areas with the most efficient orientation and full sun exposure. A photovoltaic thermal hybrid system (PVT) is used on roofs in conjunction with this to also provide for water heating, as this is much more efficient than a pure PV design, and the cooling effect of water assists in generating electricity at a much higher efficiency.
In a net zero building with such a high occupancy, it’s difficult to dismiss the energy being continuously exerted by its residents. In multifamily complexes, there is a constant ebb and flow of human activity throughout the common circulation and gathering spaces. In order to harvest this energy produced, an organized series of circulation conduits are situated throughout the building, guiding foot traffic into calculated stretches. Clusters of piezoelectric floor tiles are placed in these paths to capture the wasted energy from the applied pressure of the occupants’ footsteps, convert this kinetic energy into electricity, and then redistribute it as needed. One principal path is generated and given prominence by design. This celebrated passageway leads through the entire complex and acts as a significant generator of building form, winding its way through all major spaces, spilling out to major public and university thoroughfares, and providing some of the best vistas the site can offer. This encourages more use, further aiding in the piezoelectric energy harvesting efforts, while having the added benefit of contributing to the increased overall health of the occupants.

PHOTOVOLTAIC PANELS pv panels harvest solar energy to create electricity for use in the building the complex holds a 2,090 KW photovoltaic system.
CROSS + SHAFT VENTILATION natural ventilation reduces the strain on typical HVAC systems and allows for a more eco friendly and economic way to cool the building.
HEAT ISLAND MITIGATION vegetation collects and reduces heat build-up in an urban environment.
IMPLUVIUM TYPOLOGY the ancient roman typology of impluviums capture rainwater from the rooftop and collect it in a basin below. the collected water will then evaporate over time, cooling the building through this state change. SHADING + INDIRECT LIGHTING solar shading helps mitigate heat gain in the building, while also allowing the maximum amount of natural light to penetrate the units, decreasing the need for artificial lighting.
