While circular economy is often discussed in relation to the architectural object through the lens of material recycling, design for disassembly, and material passports, the framework is most fully enacted at the neighbourhood and city scale. Whether it is visions of circular communities that hint at some level of self-sufficiency or policies set in motion by cities, urban-scale projects exemplify the guiding principles of the circular economy, providing a glimpse into what a fully-fledged version of it might look like. The following explores the strategies used in circular urban environments, from architecture and construction materials to energy production, waste management and food production, as well as the processes and operations that govern these designs, providing insights into the conditions that inform circularity.

Olson Kundig's Hydro-Solar Generator Proposal Could Power 200 Melbourne Homes
Seattle-based Olson Kundig has released details of their second-place winner from the 2018 Land Art Generator competition, set in Melbourne, Australia. The “Night & Day” scheme combines solar energy with a hydro battery, generating enough power for 200 Australian homes, 24 hours per day.
The St Kilda-situated infrastructure proposal doubles as an artwork and pedestrian bridge, with a flagship 5,400-square-meter solar sail suspended above the St Kilda Triangle in Port Phillip city. After sunset, further electricity is generated through two turbines capturing the kinetic movement of water released through them.
Tall Tinder: Are Wooden Skyscrapers Really Fire Safe?
While interest in tall timber buildings continues to grow, there still remains one obvious concern: combustibility. So how safe are timber structures really? Arup Connect spoke with Robert Gerard, a fire engineer in Arup’s San Francisco office, to find out how high-rise wood buildings take fire safety into account.
The Case For Tall Wood Buildings
Michael Green is calling for a drastic paradigm shift in the way we build. Forget steel, straw, concrete and shipping containers; use wood to erect urban skyscrapers. In a 240 page report - complete with diagrams, plans, renders and even typical wooden curtain wall details - Green outlines a new way of designing and constructing tall buildings using mass timber, all the while addressing common misconceptions of fire safety, structure, sustainability, cost and climate concerns.
