Towards the Environmental Sustainability of the Construction Sector: Life Cycle Environmental Impacts of Buildings Retrofit

2022

In the context of the need for carbon emissions reduction, the buildingsector, as one of the most energy intensive one, needs tools and approaches towards carbon neutrality and the increase of the buildings overall energy performances. The paper proposes an integrated approach towards the environmental performances analysis of a small neighborhood having as goal the achievement of the Positive Energy District target and the assessment of its environmental impacts. The methodology proposed includes building modeling and dynamic energy simulation using the Energy Plus engine and a simplified Life Cycle Assessment approach. Two scenarios are investigated: i) the existing neighborhood, ii) the …
