Igniting Ideas from Other Insights Posted on June 15, 2022 (August 15, 2022) by Admin Futurarc Years2022 2021 2020 2019 2018 2017 2016 30-day free access to FuturArc App CategoriesMain Feature City Profile Showcase Commentary Commentary / 2nd Quarter 2022 Igniting Ideas from Other Insights by Y-Jean Mun-Delsalle June 15, 2022 We by ourselves cannot know everything and that is why cross pollination or the exchange of ideas is vital in developing innovation. This article investigates how architectural concepts brewing in other parts of the world could be applied to buildings elsewhere so that collectively, the built environment can become a solution to the current state of affairs in the climate crisis. Urban Sequoia is modelled as a skyscraper, but the proposal was developed as a toolkit that could be used on other types of buildings. Image courtesy of SOM The United Nations COP26 conference in Glasgow saw world leaders gathering to set ambitious new targets for reducing carbon emissions as the climate crisis escalates. While many of the conversations centred on finding alternatives to burning fossil fuels, insufficient attention was paid to architecture and the built environment. In light of rampant population growth and urbanisation, and the fact that the building sector currently generates 40 per cent of global carbon emissions, emerging sustainable architectural innovations should not be ignored, especially since studies have estimated that another 230 billion square metres of new buildings will be required by 2060. So, how can buildings and cities be part of the answer to the climate challenge? Three architectural firms—Behnisch Architekten, SOM and SPACE10—are proposing ideas and systems that could give insight to addressing this question, while exploring the possibility of applying them in any part of the world. HOW TO DESIGN FAÇADE SYSTEMS TO ALLOW FOR DAYLIGHTING AND VIEWS WITHOUT ADDING TO COOLING/HEATING LOADS?

German firm Behnisch Architekten completed three projects in the US and Europe that feature a new external fixed sunshade system, all based on the same principle but using different materials, dimensions and geometry. RELATED: Project | Adidas World of Sports Arena The façade system not only shields interiors from solar heat gain during warmer months, but also lets in beneficial sun during the winter, significantly shrinking cooling and heating loads. At the same time, the screen bounces daylight deep into the interior, while maintaining large apertures with views to the outside. It is unconventional to use a complex façade grid to both protect a building against solar impact while improving natural daylight into the interiors through the redirection of cooler, stray light in summer. Additionally, the inclusion of different types of screen modules in keeping with solar orientation creates a pattern that softens the scale of a building, breaking up the surface of large volumes, and gives each a distinctive appearance.

The built environment is spewing more carbon than nature can absorb, which has led to problems that include, but are not limited to, global warming and sea level rise. In terms of innovation of sustainable high-rise models within the architectural, engineering and construction industry, Skidmore, Owings & Merrill (SOM) presented a key idea that was unveiled in November 2021—Urban Sequoia, a conceptual skyscraper that aims to absorb more carbon emissions than it emits.

In the manner of rooftop gardens, the building’s façade and ‘grey’ surfaces can be covered with biomass and algae, which would breathe in up to 1,000 tonnes of carbon annually, the equivalent of 48,500 trees. After 50 years, the prototype could absorb over 400 per cent of the amount of carbon emitted by a typical building. The integrated biomass and algae façades can be converted into biofuel to power heating systems, vehicles and airplanes and used to produce biomaterials for roads, pavements and pipes, effectively creating a carbon-removal economy. These by-products could be fed back into a city-wide network where these new resources could be shared and exchanged between buildings and industries.

In FuturArc’s recent Q1 2022 issue on housing in Asia, it is clear that there is no panacea for the widening chasm that is the housing crisis, exacerbated by the global health situation. There are workable solutions, but the body (industry) needs to catch up with the brain (ideas).

Homes will be made out of cross-laminated timber (CLT)—easy to manufacture with precision, customisation, flat-pack and transport—which outperforms steel and concrete on multiple levels and has benefits in terms of sustainability, seismic performance, fire security and well-being.
