3D printing and buildings
3D printing isn't a new technology; additive manufacturing has been around for many years. The main change has been improvements in technology around additive manufacturing. This allows for more materials to be used, increases the accuracy and resolution of the products made and other benefits which have increased the scope of what 3D printing can be used for.
Blueprint Charts Path to Building System Efficiency
The next level of energy efficiency in buildings depends on a holistic systems approach that accounts for how building systems, facilities and the grid interact with each other. The systems approach is necessary because individual pieces of mechanical equipment and other building components are rapidly approaching technical and economic limitations for energy efficiency, meaning that it will cost more and more to achieve marginal efficiency improvements.
Energy efficiency gains at risk of slowing down without renewed government focus
Global energy intensity – the energy used per unit of gross domestic product – fell by 1.8% in 2016, a sign the global economy generated more value from its energy. Improvement seen in 2016 confirms the strong progress seen since the start of the decade. But this progress masks some concerning policy trends. While efficiency codes and standards grew to cover about 32% of global energy use in 2016, nearly all of the increase in coverage came from existing policies and over two-thirds of global energy use is still not covered.
