In recent years, great efforts have been devoted to research and develop the low-energy and sustainable building technologies, in terms of integrating the renewable energy sources into buildings [2], employing the emerging high-performance devices [3], developing novel building design method [4], applying data-driven modelling to improve building operation efficiency [5], guaranteeing indoor thermal environment through energy-efficient solution [6], enhancing the thermal insulation of building envelopes [7], and etc.
