Abstract

This article presents a novel software tool for the assessments of life-cycle environmental impacts and costs, which is aimed to support decision-making in the design phase of retrofit interventions in the building sector. By combining Life Cycle Costing (LCC) and Life Cycle Assessment (LCA) calculations and functionalities, this tool allows evaluating the long-term trade-offs between economic and environmental performance of investment projects in energy efficiency for buildings, while accounting for uncertainties in input parameters and economic scenarios. A major novelty of the software tool is the stochastic nature of both the LCC and LCA dimensions. The LCA is implemented with Monte-Carlo methods, while the LCC accounts for the probabilistic interdependence of macroeconomic variables over time. The software also includes advanced specific tools for parametrization and sensitivity analysis. Exemplary applications are presented in order to illustrate the novelty and the functionalities of the software tool.

Subjects
Insulation systems, Energy saving potential, Guidelines, Visual assessment, Decision making
Abstract

This report is one of five deliverables related to WP6 ‘Development and evaluation of guidelines and web-based preliminary assessment tool‘. The prime objective of WP6 is to develop and to assess written and web-based guidelines and a web tool (including a feasibility study of possible input and output data) for renovation of historic buildings with internal insulation. This deliverable contains the written guidelines, referring to Task 6.1, consisting of a guideline for setting the goal of applying internal insulation (Section 3), a guideline for deciding whether a building is suitable for internal insulation (Section 4), a guideline for selecting an internal insulation system (Section 5) and a guideline for evaluating the energy saving potential and the environmental impact (Section6). The written guidelines are also made accessible through a web-site, described in deliverable D6.3.

39. Internal insulation of historic buildings: a stochastic approach to life-cycle costing within RIBuild EU project

Abstract

The application of internal insulation is a widespread and effective solution for energy renova-tion of historic buildings. However, it entails quite high installation costs and a certain risk of failure due to moisture-related problems. A probabilistic risk assessment of both hygrothermal performance and life cycle costs can be used to address internal insulation issue, in order to support risk management and decision making. This paper presents the application of a proba-bilistic approach to Life Cycle Costing developed within the EU project RIBuild (Robust Inter-nal Thermal Insulation of Historic Buildings), to five internal insulations solutions widely used in Italy. The method provides estimates of the range and likelihood of global costs and payback periods, also considering alternative energy and future economic scenarios. The impact of in-sulation systems service life on global costs is also addressed, in order to highlight the possible connection of the method to a stochastic estimation of insulation systems durability based on hygrothermal and damage assessments.

44. Preliminary Study of The Influence of Different Modelling Choices and Materials Properties Uncertainties on the Seismic Assessment of an Existing RC School Building.

Abstract

This paper studies the influence of some aleatory and epistemic uncertainties on the seismic behaviour of an existing RC school building through a codified sensitivity analysis that uses pushover analyses and a logic tree approach. The considered epistemic uncertainties, i.e. diaphragm stiffness and modelling of stairs, seem not influencing the final assessment in term of index of seismic risk. Vice versa, aleatory ones, i.e. concrete and steel mechanical properties, strongly affect the Index. For this reason, investigations and tests should focus on the study of the mechanical properties, and, in particular, on the study of columns' concrete mechanical properties, which have the largest impact on the building seismic response.

Abstract

This paper presents the first results of a study aimed at evaluate the effectiveness of a strengthening technique able to connect masonry elements, stitching them, based on the use of basalt fibre ropes. To assess the effectiveness of proposed technique, experimental and FEM analysis has been performed. The reproduced masonry is the "three-leaf wall", where an inner core of rubble material is included between two outer brick shell, a masonry typology often found in Italian historical building heritage. The results indicate the efficacy of this dry retrofitting system, increasing the performance of masonry wall specimens. [ABSTRACT FROM AUTHOR]
