Solutions towards Zero Carbon Buildings

According to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (contribution of WG III on mitigation), historical cumulative net CO2 emissions between 1850 and 2019 amount to about four-fifths of the total carbon budget for a 50% probability of limiting global warming to 1.5°C. Progressing towards net-zero GHG emissions is therefore necessary, both in new constructions and by retrofitting existing buildings. This Special Issue deals with novel solutions for reaching this objective and, particularly, new zero-carbon building concepts and low-carbon construction products, e.g., bio-based materials; low-carbon equipment for heating, cooling, hot-water production, ventilation, and lighting; integration of renewable energy systems in buildings; energy-efficient building management and control systems; and applications of IoT and/or AI in buildings.
