Thermal properties of multi-purpose mortar mixtures: experimental characterizat...
Penazzato, Luca; Cosentino, Lívia; Turco, Chiara; Mateus, Ricardo; Oliveira, Daniel V.A considerable portion of existing buildings requires renovation. In Europe, there is a growing demand for integrated renovation strategies that reduce seismic vulnerability and improve energy efficiency. Retrofitting techniques, such as composite systems, use mortars with specific properties developed to fulfil a structural function. However, these mortars can also be used to improve the energy performance of ...
The challenge of integrating seismic and energy retrofitting of buildings: an o...
Penazzato, Luca; Illampas, Rogiros; Oliveira, Daniel V.Recent earthquakes and escalating energy demands are exposing building stock deficiencies, particularly in terms of seismic resilience and energy efficiency. Many aged constructions do not fulfil current regulations both in terms of seismic and thermal design principles, thus requiring suitable retrofitting solutions. Integrated approaches for concurrent seismic and energy renovation have emerged as promising s...
Mechanical performance and microstructual investigation of binary and ternary l...
Penazzato, Luca; Illampas, Rogiros; Rigopoulos, Ioannis; Ioannou, Ioannis; Oliveira, Daniel V.The increasing demand for sustainable building products with lower carbon footprint is a huge global challenge that can hardly be faced by conventional cementitious mixtures. In this context, the use of alternative primary binders, such as hydraulic lime, should be explored. Research in this direction should aim at the development of innovative eco-friendly materials with suitable mechanical performance. For th...
A holistic modular solution for energy and seismic renovation of buildings base...
Lopes, Lucas; Penazzato, Luca; Reis, Daniel C.; Almeida, Manuela Guedes de; Oliveira, Daniel V.; Lourenço, Paulo B.This paper introduces a novel modular retrofitting solution to enhance the energy efficiency and seismic resilience of building façades, particularly within the Portuguese context. In the context of Europe’s “Renovation Wave” strategy, and as a product of the nationally funded ZeroSkin+ project, the proposed renovation solution addresses the urgent need for sustainable building renovations to help mitigate clim...
Development of an eco-friendly lime-based mortar suitable for integrated retrof...
Penazzato, Luca; Sakhizada, Mirwais; Illampas, Rogiros; Teixeira, J. Carlos; Imbimbo, Maura; Oliveira, Daniel V.In the last decades, the European building stock has been affected by several seismic events, causing human losses and considerable economic damage. Indeed, many existing constructions exhibit deficient seismic behaviour due to the outdated or total absence of design methods used in the past and/or due to the lack of maintenance over the years. This has promoted an increasing focus on the development of retrofi...
Numerical investigation of a medieval masonry arch bridge based on a discrete m...
Penazzato, Luca; Oliveira, Daniel V.; Rapicavoli, Davide; Zampieri, Paolo; Lourenço, Paulo B.; Caliò, Ivo; Pellegrino, CarloSince ancient times masonry arch bridges have been used to cross natural obstacles. Many examples are still present and under service, particularly in European countries. Due to the historical and cultural value of these bridges, together with their important role in the transportation network system, it is necessary to have numerical tools suitable for an accurate structural assessment of their conditions, bot...
Seismic and energy integrated retrofit of buildings: a critical review
Ademovic, Naida; Formisano, Antonio; Penazzato, Luca; Oliveira, Daniel V.The European building stock presents pertinent issues needing suitable strategies to be solved. In detail, this regards seismic safety and energy efficiency of buildings to ensure more liveable and safe cities, which represents an important goal for modern societies. Energy performance includes both comfort and saving, the latter required for a more responsible resource consumption within the building sector, h...
