Sustainability

Mass timber has been hailed as the solution to architecture’s notorious sustainability problem – that buildings account for nearly 40% of global energy use is by now a worn and overcited fact. But timber isn’t the world’s only renewable material, and architects and engineers have begun looking elsewhere for other possible steel and concrete replacements. One such possibility that has recently come to light is engineered or laminated bamboo, a highly sustainable and structurally impressive material. Below, we investigate how laminated bamboo is made, what its primary qualities are, and how it compares to timber.

Bridge House is located in Coves Noves, a residential area in the north-east coast of Minorca island, Spain. Its generous plot of 2400sqm allows the dwelling to stretch horizontally to capture the surrounding’s best landscape views. At the same time, its rotating volumes create surprising interior spaces and never repeating outlooks. Based on the assembly of squared and pentagonal plans, these small polyhydric volumes stack and hover over the existing landscape with playful lightness. Their bridge-like composition gives the house its name. Breaking down the program into smaller units seemed a more respectful way to place a large program onto the site. The outer terraces and pool are designed as a direct extension of the indoor plan, following its same geometries and keeping the vast majority of the plot untouched.

CUBOESIA is a hybrid pavilion that unites architecture, design, sculpture, landscaping, sound and poetry proposing a kind of multisensory land-art installed on the lawn of the Mangabeiras Palace, a former state governor’s suburban residence, hosting CasaCorMG 2019 in, the main brazilian architecture, design and landscape fair, in the city of Belo Horizonte.

The global climate crisis is not only forcing us to rethink architectural design and the way we live, but also the materials and products that shape our built environment, starting from its origins and manufacture. Toward this end, wood has become an efficient alternative to steel and concrete – materials with high levels of embodied energy – and has led to some important architectural innovations that may culminate in its more widespread use worldwide.

Rammed earth has been used in construction for thousands of years, with evidence of its use dating as far back as the Neolithic Period. Commonly used especially in China, the technique was applied to both ancient monuments and vernacular architecture, with the Great Wall utilizing the technique. Though interest in rammed earth declined in the 20th century, some continue to advocate its use today, citing its sustainability in comparison to more modern construction methods. Most notably, rammed earth structures use local materials, meaning they have low embodied energy and produce little waste. Below, we describe how to build with this material.
