Abstract
The retrofit solutions studied herein aim to improve the seismic and energetic behaviours of existing masonry buildings to guarantee safety and the preservation of the building heritage. The retrofit consists of timber-based products (panels and strong-backs) fixed to the masonry walls using mechanical point-to-point connections; the durability and the hygrothermal performance of the solutions are guaranteed by insulation layers and membranes. The thermophysical properties of the retrofitted walls were evaluated by means of analytical and numerical analyses, considering the heat transmission in both steady and unsteady state conditions and the thermal bridge in correspondence with the corner of the wall. The in-plane seismic behaviour of the retrofitted walls was numerically investigated through nonlinear analyses. The influence of various parameters (such as masonry and insulation properties) on the performance of the retrofit solutions was analysed via parametric simulations.
Highlights
Recent directives from the EU Commission, such as the Energy Performance of Buildings Directive (EPBD) and the Energy Efficiency Directive (EED) [1], aim at implementing energy efficiency in buildings and encourage renovation of the existing building stock, which for the largest part was built before the introduction of any energy standards
The structural retrofit consists of timber-based products connected to the masonry walls using mechanical or adhesive point-to-point connections, while the durability and the energetic performance of the intervention are guaranteed by the installation of insulation layers and membranes
The retrofit solution SB_80iav is the most effective, as it allows the installation of a greater insulation thickness while respecting the maximum thickness constraint
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Due to both heating and cooling, can be significantly reduced by improving the performance of the building envelopes, renewable technologies and innovative design In this regard, the use of bio-based insulating materials (e.g., timber-based products) can help reduce the carbon footprint. Structural, energetic, and architectural aspects must be considered simultaneously to obtain a cost-optimal renovation [3,4] In this respect, the use of timber elements appears as promising. The structural retrofit consists of timber-based products (panels and strong-backs) connected to the masonry walls using mechanical or adhesive point-to-point connections, while the durability and the energetic performance of the intervention are guaranteed by the installation of insulation layers and membranes. Experimental and numerical on masonry walls retrofitted with panels timberhave panels have been reported.
