In 1972, a group of El Cerrito residents decided to create a recycling center and asked the city council for a small patch of land that had previously housed a rock quarry and then a landfill. The operation was so successful that it outgrew its volunteer roots, and the city took over operations in 1977.
As recycling programs expanded, the layout of the small site proved problematic, with operations vehicles crossing paths with residents dropping off materials. The city commissioned the design-build team of Charles Pankow Builders and Noll & Tam architects to design a new center that would offer improved public recycling drop-off facilities, accept a broader range of materials, provide offices for the city's environmental services division, and promote environmental responsibility.
The new center's structures and drop-off bins are organized in a circular plan that safely separates operations and visitors' paths of travel, while providing intuitive wayfinding. New signage guides visitors and educates them about the value and processes of recycling.
Designed to achieve zero-energy usage, the facility is anticipated to receive LEED Platinum certification under the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) rating system. Sustainable design elements include 10kW of solar photovoltaic panels, an 11,000-gallon cistern for rainwater collection and reuse, native plantings, rain gardens, and extensive daylighting and energy-efficiency strategies.
The 2,200-square-foot net-zero-energy administrative building, mostly constructed off-site, consists of two custom modular structures connected by a tall central cupola with high clerestory windows. Modular construction produces less than half the construction waste of site-built construction. Natural lighting provides most of the building's lighting needs. A mixed-mode mechanical system relies on natural ventilation for most of the year.
The 6,400-square-foot operations building is a tall, open structure, with a 20-foot clearance under the roof to allow the movement of heavy machinery and tall stacks of material. The main processing shed has a butterfly roof that sheds water into the rainwater harvesting system to be filtered by bioswales. Rainwater is reused for flushing toilets and urinals and irrigating landscaping.
The highly popular materials exchange zone, where residents can drop off used items for others to take, has been quadrupled in size to 1,200 square feet, with custom-designed wood shelving and a patio with benches.
The center itself is recyclable, designed for deconstruction and reuse when it is no longer needed. Its wood and steel structural systems are easy to unbolt and reorganize.

When SunPower Corporation, a provider of solar cells and panels, chose three existing single-story concrete tilt-up buildings in San Jose to house its new headquarters, Valerio Dewalt Train Associates was called on to transform the grounds and buildings with photovoltaics and cutting-edge product development technology while enhancing opportunities for creative interaction among employees—all on a strict budget.
The 185,000-square-foot project provides office space for approximately 500 employees, with open workstations, private offices, and conference rooms. The facility also includes a fitness center, a full-service cafeteria, a corporate training center, and a customer briefing center. In addition, one of the three buildings houses a research and development laboratory with a class 1000 clean room and flexible general lab space for lab benches and testing equipment. Design/construction costs were kept to $80/square foot.
To facilitate interaction, the ratio of open workstations to private offices is 80/20, and the 6′ x 8′ workstations are only 30 inches high. To break up the expansive interiors, the design team introduced "cork clouds," subceilings that define neighborhoods of workstations within the overall space, which has 14-foot-high ceilings. Collaboration areas with stools and tables are placed between open workstation areas and encircled with wooden posts below lighted panels. Conference rooms and private offices are consolidated along one wall, with lower grid ceilings.
To create visual drama economically, the design team specified wide linear swathes of carpet in two color patterns, black/gray alternating with an intense green. The design team also provided imagery of completed SunPower's product installations for environmental graphics that enliven the walls of conference rooms, the customer briefing center, and the lobby.
The addition of skylights throughout brings in plenty of daylight, starting with the lobby's 28-foot-long skylight. To make the most of the other skylights, which are six feet wide, the designers linked them to the dropped ceiling via cones that expand to twelve feet in diameter, greatly increasing natural light penetration. Walls within the space alternate five-foot sections of glazed and solid walls to enhance visibility and allow daylight to penetrate.
The project is targeted to achieve a LEED-CI Gold certification from the U.S. Green Building Council. Sustainable strategies include low-flow plumbing fixtures; bioswales in the courtyard that treat stormwater runoff; and an area with bicycle storage, changing rooms, and showers to encourage employees to bike to work. Modest structural upgrades to one of the buildings allowed it to accommodate rooftop photovoltaic panels, which are also placed on top of the new carport structures. In addition, the entry sign integrates vertically mounted photovoltaics.

Merritt Crossing is a new high-density, transit oriented development by a non-profit providing affordable apartments and services for low-income seniors in downtown Oakland. Located at the edge of Oakland's Chinatown neighborhood near the Lake Merritt BART station, the project transforms an abandoned gas station site by an interstate highway into a new community asset. The non-institutional design combines colorful siding and panels with plant supporting wire mesh screens to compliment the neighborhood's eclectic pan-Asian residential character. The building's community-building amenities include on-site supportive services, a community room, and a landscaped courtyard and garden. The sustainable design is expected to achieve the highest level (Platinum) under the LEED for Homes rating system in addition to a high GreenPoint rating, Energy Star Rating and Bay Friendly landscaping certification. The building's innovative sustainable systems include both photoelectric power and solar water heating, storm water retention, filtered ventilation, rainscreen facades and recyclable metal framing.
• 70 affordable apartments for a diverse group of seniors with low incomes
The building was arranged along the long edge (Sixth Street) of the corner site in order to reserve a twenty foot sideyard for a sunny landscaped courtyard and garden. This configuration also allows the courtyard to be directly linked to the ground floor community room, kitchen, laundry and entrance on Oak Street. The courtyard garden is designed as a series of outdoor spaces from community to more private activities. The high ceiling ground floor areas are surrounded by glass walls to enhance the visual connectivity of the community spaces and the public sidewalk. The footprint of the required on-site parking is reduced by the use of stacked parking lifts. The parking garage is wrapped with green screen panels that will create a living wall along the sidewalk and courtyard. In addition, planting beds are tucked under the street side of the building and double function as storm water retention tanks. By reducing the visual footprint of the ground floor level, the upper floors appear to float above which lightens their impact. The upper floors are organized into two parallel bands of apartments separated by a wide hallway combined with the fire stairs and elevators. The ends of the hallways are open with large windows to provide views and introduce daylight. Many of the apartments are provided with balconies that are recessed into the building mass. On the south (red) façade, the balconies are part of a recessed zone that mitigates the visual and noise impact of the adjacent freeway at the same time providing solar shading. The variety of openings and plant supporting mesh panels provides a freeway scale composition. On the north (green) faced the opening configuration provides a scale and variety compatible with the adjacent residential neighborhood. The building's color scheme accentuates the separation between the two bars of apartments and between the outer building "skin" and the internal balconies and voids.

Called Dia (the Portuguese word for day) referring to it’s one-piece-a-day system that allows you to complete the puzzle as the year goes by.
This concept allows you to see the year pass more naturally letting you interpret the time that passes in a more intuitive and direct way, giving you a notion of how much time has passed and how much time you have left in the month or year.
Because this system is based on modified puzzle pieces, that link to any neighboring piece, it allows an easy colour based organization, that turns this time keeping object into a game of drawing as if each piece was a pixel. This allows an expression of how you see the year, how you personally relate to it, or wish it will be.
Each one of the 366 (366 because of leap years) is marked with the day and month that it represents, and because of this free way of organising the calendar becomes perpetual, being adaptable to any year.

Dutch architect Serge Schoemaker has revealed his design for the redevelopment of Fort near Hoofddorp (1907) in the Netherlands. With a redevelopment of the historical site local authorities aspire to make the world heritage monument more known and open to the public. Schoemaker’s conversion design transforms the 8’100 m2 large fort island into an open air theater and restaurant.
Fort near Hoofddorp is located in the middle of the Haarlemmermeer polder in the Province of North Holland. The fort is part of the Defence Line of Amsterdam, which extends 135 kilometres around the city of Amsterdam, on a radius of approximately 15 kilometres from the city center. The Defence Line, built between 1880 and 1920, consists of a unique system of inundation areas, including 42 forts. It was inscribed onto the UNESCO World Heritage List in 1996.
Fort near Hoofddorp was realized as a two level building because of the limited size of the construction site. The fort island encompasses several underground tunnels which connect the former gun emplacements, among others the unique caponier at the circular fort moat. The 1’200 m2 fort building is made out of in-situ concrete without reinforcement. The concave shaped concrete ceiling of the upper floor has a thickness of up to 1.8 metres to hold attacks of enemy gun fire.
The redevelopment design of Fort near Hoofddorp will envision a restoration of both the fort building and island. An entrance bridge will reappear on its original position above the fort moat. Offering great views over the historical surroundings, the small elevated square on top of the fort island will become the new heart of the island: the surrounding green-clad fort walls enclosing the square will be converted into terrace-shaped tribunes generating a 300-seat open air theater.
During conversions in the past the massive room-dividing walls within the fort building have been demolished. The historically incorrect but spacious situation has been used to create an interior design which both refers to the original layout and benefits from the new characteristics: dark wooden tables will be hung using black steel frames at the lowest points of the massive concave ceilings; the former positions of the room-dividing walls. The hung table constructions will emphasize the solidness of the concrete ceiling in a functional way.
