Construction: Building for the future

The construction industry has a heavy carbon footprint, accounting for some 40% of global emissions, and yet, as the world’s population grows, demand for housing and building is only soaring. We kick off 2021 by looking at how the construction sector can become greener and some of the radical solutions required. We speak to sustainable architecture expert Dr Catherine De Wolf about the need to design recyclable buildings and how that will require a fundamental restructure of the way the construction industry works. We look at nearly zero energy wooden homes and investigate whether this material can help us kick our concrete habit – concrete being the most used substance on Earth. We home in on techniques to make cement greener and piezoelectric to light up spaces with the addition of vegetable waste, and at how self-healing building materials can prolong the life of civil infrastructures. And we explore the promise of fungal architecture to see whether structures grown from fungus can green the way we build.
