Just make sure you put the lid down first

When it comes to sustainable building, the march of progress is less a straight line than a meandering path with many forks, frequent hairpins and quite a few dead ends. The result is that 2015’s product landscape is an unlikely combination of the very new and the very old. High-tech solutions such as LED lighting and 3D scanning will reduce the energy use of buildings, whereas low-tech materials such as clay and wood are set to enjoy a renaissance as people search for natural, renewable materials with low embodied carbon. In this article for Construction Manager’s Agenda section, I reviewed sustainable building trends and picked out 10 products we’re likely to see more of this year. Look out for carbon-negative bricks, passive ventilation systems concealed in chimney stacks, clay boards with embedded phase-change materials and high-pressure toilets that only use 1.5L of water for each flush.
