The Alcoves, true underground galleries - Montreal Insectarium, Canada

As we enter underground galleries inspired by insect habitats – the Alcoves – the perception of the world as we know it changes. All the senses go on alert in each of the rooms: you’ll perceive the environment the way an insect does. ... Insects’ vision is nothing like our own. In the first hall of the Alcoves you’ll find on the screens that surround you abstract projections of numerous geometric shapes that allow for a better grasp of how insects use their vision in their environments. ... As you pass, the images are transformed according to the speed and range of your movements, reacting to the details of your silhouette. You’ll quickly notice that every little gesture is interpreted differently in the world of the infinitely small.

Sustainable tunnel renovation tender scalable innovation

Sustainable tunnel renovation tender scalable innovation | Underground space | Scoop.it
Emission pollutants such as nitrogen oxides lowered substantially due to the introduction of Electric Vehicles (EV's) and stricter emission standards for air quality improvement. However, the concerns about fine dust pollution PM2.5 is far from over. Since carbon isn't the only fine dust emission stemming from traffic, the focus must be on reducing all forms of fine dust stemming from traffic, roads and tunnels. Tunnel exits are fine dust hotspots all around the world. Worldwide many tunnels are located in urban areas which have impact on the inclusive livability of cities and its citizens. Learn more about the world's unique system for sustainable fine dust removal from tunnels.

The trenches were lined with concrete, and a brick arch or steel supports were added across the top so the road could be restored. Damage to nearby buildings was minimal, but the project was not without setbacks. ...

Tunnelling must communicate on climate change now, says new ITA president

Tunnelling must communicate on climate change now, says new ITA president | Underground space | Scoop.it

Professor Dix, who is a barrister and scientist specialising in underground space, fire and life safety, was elected as president on 7 September 2022 at the ITA’s general assembly, which was held at the World Tunnelling Congress in Copenhagen. As well as serving on the ITA’s executive council and working groups, he is a member of the National Fire Protection Association (NFPA) and PIARC, the world road association. Dix succeeds Jinxiu (Jenny) Yan, the association’s first ever female president.

Dix’s argument is that the tunnelling industry needs to articulate the benefits of underground space and infrastructure through the language of climate change, in ways that can be clearly understood by non-engineers. “It’s not just about carbon, it’s about our social, economic and environmental footprint and what we can deliver for society,” said Dix, addressing the ITA young members’ session at the congress.

Study ranks Auckland as the world’s 'spongiest' city - New Zealand

Study ranks Auckland as the world’s 'spongiest' city - New Zealand | Underground space | Scoop.it

Auckland, New Zealand has been ranked as the world’s ‘spongiest’ city by engineering consultancy Arup.

The firm’s Global Sponge Cities Snapshot report examined the amount of green space and permeable local soil in seven major global cities – London, New York, Singapore, Auckland, Mumbai, Nairobi and Shanghai. The study covered approximately 150 square kilometres of each city’s main urban centre, using land analysis tool Terrain to determine which cities were the most absorbent.

New Zealand’s largest metropolis came out on top, while London was ranked as the least spongy city. “Given the challenges of climate adaptation, cities can’t go on being concrete jungles, in conflict with nature,” said Arup’s Global Water Leader, Mark Fletcher. “Every city has unique natural assets – grasslands, forests, parklets, lakes and ponds – [and] these need to be quantified, valued and utilised in the same way we treat other vital resources.
