Redirecting Sunlight Into Dark Urban Alleys With Translucent Panels

Hundreds of millions of people throughout the world live in crowded urban areas that don’t receive much sunlight — largely due to the presence of tall light-blocking buildings. As the global population continues to climb (that’s the prediction) over the coming decades, this problem is expected to worsen considerably. So, … [continued]

Passive Houses Could Help Norway Significantly Reduce Its Energy Consumption And Carbon Emissions, Research Shows

Norway could significantly reduce its energy consumption and carbon emissions simply by ensuring that the Norwegian housing stock is built according to, or upgraded to, a passive standard, according to recent research from the Norwegian University of Science and Technology (NTNU). The passive standard is a rigorous, voluntary standard for … [continued]
