Climate change: trees to the rescue
Bringing nature back into cities, in the form of trees, can help fight global warming. Climate change is the challenge of the century. The last UN Environment Emissions Gap Report warned that, in order to ensure global warming stays below 2°C, efforts should be tripled, and if we want to stay below 1.5°C, they should
Affordable green homes
Some proponents of affordable housing may be under the impression that sustainable homes are more expensive to construct and maintain than those built using traditional means. However, there are actually a number of sustainable practices that can make green homes more affordable than traditional homes for their inhabitants. There are a number of cost-effective green
3D printed bioplastic: the future of construction?
To date, most 3D printed buildings have been built from concrete. Could 3D printed bioplastic be a more sustainable option? Additive manufacturing, or 3D printing, is a major part of the fourth industrial revolution and it will transform the construction sector, according to Zoubeir Lafhaj, an expert in the future of construction, from the graduate
Bio concrete and other construction materials from local resources
As global housing programs are gearing up, the world will need a staggering amount of construction material over the next few decades. This will put a strain on resources, and produce a lot of CO2; unless we discard the present one-size-fits-all approach to materials use (on the basis of Portland cement) and develop local and
Self-healing concrete in full development
Concrete degradation is one of the most costly problems of our time. Concrete will always crack, although less so if well-designed and well-constructed. Cracks will allow water and air to enter into the structure and eventually reach the steel reinforcement. When this erodes, it swells, causing more cracks. Concrete degradation of our infrastructure now requires
The many faces of hemp
The ecological properties of hemp makes it one of the types of insulation used in construction with the lowest carbon emissions footprint. A relatively recent interest in hemp as a building material responds to a global trend that encourages the development of bio-based products and the reduction of carbon emissions. But its use dates back
Straw, an excellent construction material
Researchers of the University of Bath (UK) and ModCell Ltd have developed straw as a low-impact and viable modern building material. As they say, ‘our research has made affordable, environmentally-friendly houses a reality. The first super-insulated, low-carbon straw houses are hitting the open market.’ Straw, scientifically proven Many disruptive construction technologies have been proposed as
Biobased means thinking in short cycles
Biobased really is a sub-branch of circular, says Daan Bruggink of ORGA architects. The circular economy knows two cycles, technical and biological. The biological cycle of course contains the ‘real’ natural materials: wood, reed, fibre, flax, and so on. Technical materials such as foam are often fossil-based. We should reuse or recycle 100% of these
