“…In fact, the early stages of building design, when main decisions are taken, are the stages with the higher influence on the life cycle performance of buildings as suggested by Gervásio et al [221]. However, in these stages, data is often scarce so that LCA approaches are limited.…”

The improvement of the use of renewable energy sources, such as solar thermal energy, and the reduction of energy demand during the several stages of buildings' life cycle is crucial towards a more sustainable built environment. This paper presents an overview of the main features of lightweight steel-framed (LSF) construction with cold-formed elements from the point of view of life cycle energy consumption. The main LSF systems are described and some strategies for reducing thermal bridges and for improving the thermal resistance of LSF envelope elements are presented. Several passive strategies for increasing the thermal storage capacity of LSF solutions are discussed and particular attention is devoted to the incorporation of phase change materials (PCMs). These materials can be used to improve indoor thermal comfort, to reduce the energy demand for air-conditioning and to take advantage of solar thermal energy. The importance of reliable dynamic and holistic simulation methodologies to assess the energy demand for heating and cooling during the operational phase of LSF buildings is also discussed. Finally, the life cycle assessment (LCA) and the environmental performance of LSF construction are reviewed to discuss the main contribution of this kind of construction towards more sustainable buildings.

“…One example is the SB_Tool, also designated as ESSAT (early stage sustainability assessment tool), and developed by SB_Steel research project partners, mainly by the University of Coimbra research team, for the evaluation of the life cycle environmental performance of a building, which is freely available online [10]. This tool was an outcome of the European research project "SB_Steel-Sustainable buildings in steel" [11][12][13].…”

The market share of lightweight steel-framed (LSF) construction system has grown over the last decades, mainly in low-rise residential buildings, due to its advantages such as having small weight with high mechanical strength; reduced disruption on-site and speed of construction; great potential for recycling and reuse; high architectural lexibility for retroiting purposes; easy prefabrication, allowing modular construction; economy in transportation and handling; superior quality given of-site manufacture control; and excellent stability of shape in case of humidity and resistance to insect damage. However, given the high thermal conductivity of steel and the lightness of this type of construction, it may also have some drawbacks if not well designed and executed. Therefore, special atention should be given to the LSF building envelope in order to minimize thermal bridges. Moreover, given the usual reduced thermal mass, several strategies could be implemented to increase thermal inertia, consequently reduce indoor temperature luctuations, enhance the occupants comfort and increase energy eiciency. In this chapter an overview of the main features related to the thermal behaviour and energy eiciency of LSF buildings is provided alongside some related case studies.

7Due to global warming and energy exhaustion, building retrofitting has attracted increasing attention 8 worldwide. With 67.1 billion square meters of existing building area, China normally targets separate 9 defect remedies to improve building energy efficiency in conventional renovation practices rather than 10 taking a holistic approach to optimize whole building performance. 12This article presents a working procedure that is employed in the decision-making process of domestic
