COVID19 is having important implications in the real estate sector, it is a complex situation. In this context, having information will allow us to make the best decisions. From WIRES we propose to analyze and disseminate the latest technologies, the most advanced systems and processes throughout the technical life cycle of the project; from the design phase to the final construction, which is essential to move towards optimization and sustainability. We will see how innovation in design, materials, construction and prefabrication are closely related to energy saving, resources, the environment, the fight against climate change and the circular economy from the point of view of the real estate sector. In addition, we will analyze how to meet the challenge of meeting the PNIEC objectives (by 2030 rehab. 1.2MM homes). And we will know better what the LEAN, C2C (Cradle to Cradle) construction processes, quality seals and other essential tools consist of.
