Owing to its unique blend of properties, polyvinyl chloride (PVC) has become one of the most important polymers that have been used in everyday life for many years. Its short- and long-term applications span multiple key industries such as building, electrical/electronic insulation, packaging, and healthcare. These industries produce high volumes of PVC solid items that require responsible management when they reach their end-of-life because they are not biodegradable. Simple and affordable methods of diverting this waste from landfills would contribute positively towards combating environmental problems. However, many approaches have been reported in literature and there is a need to collate for easier comparison. For example, some alternative approaches are highly effective in transforming PVC waste into a range of valuable products but are still associated with secondary pollution. This overview covers different facets of virgin solid PVC (rigid, semi-rigid, and flexible), focusing mainly on its importance, global increase in use, and waste’s recyclability. In addition to the pros and cons of different recycling strategies, the influence of specific factors on the expanding PVC market is also considered albeit briefly. Notably, [Formula: see text]50 % of the world’s annual PVC production and utilization capacity is accounted for by PVC items meant for building applications; these items also drive the growth of the PVC recycling market.

Structural design plays a very important role in reducing environmental impacts by reusing resources, recycling materials, and minimizing waste and pollution in the construction sector. Sustainable design becomes more effective than traditional solutions in achieving the transition to sustainability. The decision-making process is not simple due to the different preferences of clients, architects, and engineers. This paper aims to develop a decision framework for assessing sustainability in the early structural design stage. Multi-criteria decision-aiding (MCDA) methods have been implemented to improve the selection of regulations. A technical ranking approach, the Fuzzy Analytic Hierarchy Process (FAHP) method, has been employed to identify the optimal solution. Three alternatives including an innovative and two traditional structural systems have been selected and compared in terms of three criteria—economic, social, and environmental impacts. Nine sub-criteria for ranking the importance level of sustainable design have been determined through a literature review and professional experts. FAHP methods show that the economic impact (58%) is the most important criterion for assessing the sustainability of structural systems, followed by the environment with 31%. The social aspect contributes 11% to this method, and it is ranked as the least important criterion. This research revealed that MCDA methods can be used as a guideline for engineers to improve the selection in the process of sustainable design. The decision model proposed in this study has been verified and, therefore, can be applied for similar projects.

European non-residential buildings constructed before building energy codes consume more energy and resources than new buildings. Existing educational buildings comprise 17% of this outdated stock. These buildings can be retrofitted to create a conducive learning environment that can improve students’ comfort. The refurbishment of facades is a common solution to improve the energy performance of schools when the aim is to improve the daylighting comfort. This study develops a methodology to optimize facade renovation solutions including (1) preparation, (2) simulations of the simplified model using local shading, and (3) modeling a realistic optimized facade design. This study evaluates visual comfort by considering multiple-dimensional metrics such as useful daylight illuminance (UDI), annual sunlight exposure (ASE), illuminance uniformity, and the daylighting factor. The three parameters of the louvres on which this study focuses are the distance from the new facade to the exterior wall, the blade degrees, and slat spacing. The methodology was first applied to improve the facade proposal with reused roof tiles from the project Waste-based Intelligent Solar-control-devices for Envelope Refurbishment (WiSeR). The results illustrate that implementing these solutions efficiently improves the indoor visual comfort in the classroom while avoiding overheating issues. For a constant-gaps surface, a shading distribution with alternated gaps gives better results for the aforementioned light metrics. Specifically, the most suitable values are a 7 cm distance from the new shading system to the existing wall, slat degrees at 0, and louvre spacing at 21 cm.
