This research aims to contribute to quantifying whole building life cycle assessment using various software tools to determine how they can aid the construction industry in reducing carbon emissions, and in particular embodied emissions, through analysis and reporting. The conducted research seeks to examine and compare three whole building life cycle assessment tools; Athena Impact Estimator, Tally and One-Click LCA to relate the input variability to the outputs of the three programs. The three whole building life-cycle assessments were conducted using a case study building with an identical bill of materials and compared to determine the applicability and strengths of one program over another. The research confirmed that the three programs output significantly different results given the variability in scope, allowable program inputs and generated “black-box” back-end calculations, where the outputted whole building life cycle carbon equivalents of One-Click LCA is less than half than of Tally meaning the programs outputs cannot be simply compared side-by-side.

The Social

Environmental and economic impact assessment of products have a long record, while social performance analysis of products have less references in the scientific literature due its particularities and the adaptations needed for the features of the studied subject. In addition, there is a lack of a methodological framework of its application in the analysis of value chains, with the aim of estimating the impacts of technical innovations from the social point of view. This paper describes the theoretical framework and impact assessment approach for the Social Life Cycle Assessment of product value chains under a circular economy approach by applying a scoring system in different subcategories and indicators, considering the plastic packaging sector as a case study. Twelve subcategories have been chosen, because of their relevance to the case study, related to the impacts on the labor conditions, consumers’ well-being, end-of-life of the product, local community conditions, technology and suppliers, among others. The validation of the methodology in the plastic packaging sector is done by considering the main stakeholders involved in the value chain and the particularities of the sector.

Extending the lifetime of passive products, i.e., products that do not consume materials or energy during the use phase, by implementing product-service systems (PSS) has a potential to reduce the environmental impact while being an attractive and straightforward measure for companies to implement. This research assesses the viability of introducing PSS for passive products, by documenting five real product cases of prolonging the lifetime through repair or refurbishment and by quantifying, through life cycle assessment (LCA) and life cycle costing (LCC), the change in environmental and economic outcome. The environmental impact (measured as global warming potential over the life cycle) was reduced for all cases because extraction and production dominated the impact. This reduction was 45–72% for most cases and mainly influenced by the number of reuses and the relative environmental burden of the components whose lifetime was prolonged. The costs for the company (measured as LCC from the manufacturer’s perspective) decreased too by 8–37%. The main reason that costs reduced less than the environmental impact is that some costs have no equivalent in LCA, e.g., administration and labor costs for services. The decreases in both LCA and LCC results, as well as the willingness of the companies to implement the changes, demonstrate that this measure can be financially attractive for companies to implement and effectively contribute to a circular economy.
