A Qualitative Analysis Using Thermography for Characterization of the Built Env...
Ferreira, Ana Vaz; Ferreira, Pedro; Santos, Michael M.The revised Energy Performance of Buildings Directive (EPBD) recognizes nearly zero-energy buildings (nZEB) and building renovation as essential steps in the decarbonization of the built environment. A thorough understanding of existing buildings is a prerequisite for improving their thermal performance and ensuring that interventions are based on pre-existing conditions. This study investigates the use of ther...
Sustainable Vernacular Architecture to Improve Thermal Comfort in African Count...
Santos, Michael M.; Ferreira, Ana Vaz; Lanzinha, JoãoThis study highlights the importance of bioclimatic design, passive solar cooling and heating systems, and traditional building materials in improving the sustainability and thermal comfort of vernacular architecture in Africa. The lack of available technology, financial resources, and increasing urban populations are significant challenges in implementing sustainable vernacular architecture. To overcome these ...
Overview of Energy Systems in Africa: A Comprehensive Review
Santos, Michael M.; Ferreira, Ana Vaz; Lanzinha, JoãoAfrica has abundant solar resources but only 2% of its current capacity is generated from renewable sources. Photovoltaics (PV) offer sustainable, decentralized electricity access to meet development needs. This review synthesizes the recent literature on PV in Africa, with a focus on Mozambique. The 10 most cited studies highlight the optimization of technical components, such as storage and bifacial modules, ...
Reducing cement consumption in mortars by waste-derived hydrochars
Santos, Michael M.; Marques Sierra, Antonio Luis; Amado Fierro, Álvaro; Suárez, Marta; Blanco, Francisco A.; González La Fuente, José ManuelWaste-derived hydrochars are presented for the first time as promising materials to reduce the consumption of natural resources and the carbon footprint of the cement industry, while eliminating waste and sequestering a high amount of carbon in civil infrastructures. Rice husk (RH) and stabilized organic waste from a mixed municipal waste mechanical-biological treatment plant (SOW) were subjected to hydrotherma...
Colonial moorings on spatial planning of Mozambique
Santos, Michael M.; Ferreira, Ana Vaz; Lanzinha, João CarlosEach country has its spatial planning system, which comprises several instruments and objectives focused on city issues and territorial development. On June 25, 1975, the independence of Mozambique was proclaimed, following the end of the colonial war with the military coup of April 25 in Portugal and the Lusaka agreements on September 7, 1974. Consequently, a new framework establishes the bases of public polic...
Passive Solar Systems for the Promotion of Thermal Comfort in African Countries...
Santos, Michael M.; Ferreira, Ana Vaz; Lanzinha, JoãoGlobally, the residential sector consumes a significant amount of energy. Therefore, bioclimatic architectural systems which consider passive solutions should be studied, analyzed, and implemented to reduce energy consumption. This review aims to promote thermal comfort in African countries by using passive solar systems. It begins with the keyword thermal comfort and then reviews articles published over the la...
Review on urbanism and climate change
Santos, Michael M.; Lanzinha, João Carlos; Ferreira, Ana VazThe purpose of this article is to review the literature related to urbanism and climate change. First, an overview of climate change policies is presented. A review of articles published in recent years that examine the various research subareas related to urbanism climate change and the present pandemic situation is performed. The concepts of green and biophilic urbanism have been growing and getting strength,...
Proposal for a methodology for sustainable rehabilitation strategies of the exi...
Santos, Michael M.; Lanzinha, João Carlos; Ferreira, Ana VazAbstract: Having in mind the objectives of the United Nations Development Agenda 2030, which refers to the sustainable principles of a circular economy, it is urgent to improve the performance of the built environment. The existing buildings must be preserved and improved in order to reduce their environmental impact, in line with the need to revert climate change and reduce the occurrence of natural disasters....
Proposal of methodology for evaluation of a vertical shanty building in Beira, ...
Santos, Michael M.; Lanzinha, João Carlos; Ferreira, Ana VazAbstract: Emerging economies are in an almost winless situation: they would benefit from improving the extremely poor economic situation, making them self-reliant and economically productive. However, the poor fight for daily survival and, therefore, cannot afford to improve themselves. This article describes the state of the “Grande Hotel” in the city of Beira, Mozambique, built-in Portuguese colonial times, a...
Innovative particleboard material from the organic fraction of municipal solid ...
Santos, Michael M.; Diez, Maria Antonia; Suárez, Marta; Centeno, Teresa A.This study presents a challenging approach that addresses the efficient management of the organic fraction of municipal solid waste (OFMSW) by hydrothermal carbonization (HTC) for the development of novel sustainable low-CO2 building materials. Mild HTC treatment at 180 °C for 2 h transformed low-grade OFMSW into a renewable carbonaceous solid (hydrochar), which displays promising properties for application in ...
