Green building design and architecture have become widespread tenets in the development of sustainable buildings. In this context, the use of sustainable materials and the awareness of resource/energy consumption are strategic aspects to consider for the improvement of building performances. This paper presents a new and structured approach to address uncertainty and sensitivity analysis in Life Cycle Assessment (LCA) to support the decision-making process in building renovation. This “probabilistic” approach to LCA allows for the obtaining of results expressed as ranges of environmental impacts and for alternative solutions, offering an idea of the meaning of input parameters’ uncertainties and their influence on the result. The approach includes (i) the assessment of inputs’ uncertainties (represented by Probability Density Functions—PDF); (ii) the data sampling; and (iii) the uncertainty propagation (Monte Carlo method). Variance decomposition techniques have been used to sample inputs’ PDFs and assess their impact on the LCA result distribution (sensitivity analysis). The methodology application is illustrated through a case study where three building retrofit measures were assessed. Results provide an insight about the uncertainties of LCA indicators in terms of climate change and nonrenewable energy. The input parameters related to the use phase are confirmed as the most influential in building LCA.

Hospitals are the major contributor to environmental corruption and the biggest drain onenergy in their life cycle because they are complex, multifunctional giant facilities. Several recent studieshave been carried out to find the most suitable solutions to reduce energy consumption provide it on-siteand contribute to supporting economic, environmental and social aspects. The reason for the slowmovement of green buildings for hospitals is to focus on a suitable design for the complex function thatdeals with the local climate, natural resources, economy and cultural values and avoid the one-size-fits alldesign. This made the solutions used multiple and varied, different for greening of the hospital and put theresearch in the absence of a clear perception of the mechanisms of the application of green architecture inhospitals and this identified the problem of research. Therefore, the study looked at an analytical study ofexisting project models designed according to the strategies and standards of green architecture todetermine the strategies adopted in each project, and by adopting the analytical method after determiningthe strategy used in each building to achieve the green architecture and then comparing them according tothe standards adopted using the global LEED system Green Building Council. The results that will bereached are the mechanisms of applying Green Architecture to Hospitals.
