Recently, the Architecture at Zero design competition, sponsored by Pacific Gas and Electric Company, came to a close. Open to a variety of fields and skill levels, the competition challenged entrants to create a zero net energy (ZNE) design specific to an Oakland-based site run by the East Bay Asian Local Development Corporation (EBALDC). ZNE buildings maintain equal amounts of energy input and output annually, and thus function as independent sustainable units, making them a smart solution when considering future impact.

After public outcry rejected Michael Maltzan Architecture’s winning entry “The Lens,” which sought to replace St. Petersburg Pier with an ambitious sail-like concrete canopy and aquatic habitat, the fate of the structurally inapt inverted pyramid remained in limbo. Now, two years after the culmination of the original competition, the City of St. Petersburg, Florida, alongside the preservations of the Concerned Citizens of St. Pete, has selected eight scaled back proposals in hopes that one will provide a sensible solution that will both maximize the pier’s potential and satisfy the locals.

On the occasion of Ideas City 2015, the biennial Festival created to explore the future city and to effect change, Storefront for Art and Architecture, along with the New Museum and the New York City Department of Transportation, is launching a competition for the design and construction of an outdoor structure—a work of "Street Architecture" that facilitates new forms of collective gathering and engagement with the city.

A few days ago, the winning design for the new Liget Budapest Museum of Ethnography was revealed. BFarchitecture, awarded second place, has just released their design proposal, which weaves the city and park of Városliget together by flowing the public along the Dózsa György út through the procession of the building.

The Award for Architectural Heritage Intervention AADIPA, arises from the belief that heritage, as a vehicle for social integration and an economic vitalizing resource for the community, deserves to be appreciated and encouraged. In the current context, in which architectural heritage is considered not only to be a fundamental instrument of knowledge but also a first rate socioeconomic resource for the sustainable development of the territory, the disclosure, distinction and recognition of works and quality projects contributing to the preservation of the collective memory is imperative.

Hello Nature, the most recent ideas-based challenge organised by Combo Competitions, asked participants to design a structure that celebrates nature on an expansive site in northern Sweden at the foot of Omneberget mountain. Located in an area known as the High Coast (Höga Kusten), the site sits within an UNESCO World Heritage Site. Designers were asked to "highlight the relationship between humanity and the rest of the planet" in putting forward proposals which "reconnect to nature." As a twist, entrants had to include both educational and recreational elements to their submissions. The entries, which range from a mountain of 'conservation drones' (with a control tower and charging station at its peak) to a collection of four extruded concrete plinths, all seek to explore our relationship with the wild when 50% of the world's population live in urban centres.

The London Borough of Wandsworth has launched an international call for architects and engineers interested in envisioning what could be the second pedestrian bridge to rise near the Battersea Power Station development. The two-stage ideas competition, whose announcement comes shortly after the recent approval of Thomas Heatherwick’s Garden Bridge, believes that the bridge could potentially become “one of the most expressive and visible landmarks in London.”

'Twas the month of December, when all through the house, not an architect was stirring, not even a (computer) mouse. The drawings were hung in the boardroom with care, in hopes that the client soon would be there. The designers were nestled all snug in their beds, while dreams of unlimited budgets danced in their heads. So instead of preparing for the year's final meeting, dear readers, please send us a holiday greeting!
