A simulation study to assess the impact of natural ventilation on the hygrother...
Saraiva, Nuno Francisco Baía da Silva Garcia; Gaspar, Adélio; Costa, José Joaquim daTaking a historic library of the University of Coimbra as a study case, this work is focused on assessing the impact and conservation risks of using the main door of its noblest room. From a previous monitoring campaign, it was possible to correlate important fluctuations of the indoor environment conditions with the natural ventilation induced by opening the main door. Consequently, a comprehensive study is re...
The impact of thermal transmittance variation on building design in the Mediter...
Fernandes, Marco; Rodrigues, Eugénio; Gaspar, Adélio; Costa, José; Gomes, ÁlvaroContrarily to what happens in northern European countries, buildings in the Mediterranean region are prone to overheating. Consequently, it is important to better understand the role that the thermal transmittance of the building envelope elements has on air-conditioning consumptions. This paper analyzes the effect of different U-values on building design in the Mediterranean area. 192 000 residential buildings...
A Combined Value Focused Thinking-Soft Systems Methodology Approach to Structur...
Bernardo, Hermano; Gaspar, Adélio; Antunes, Carlos HenggelerSeveral technological, social and organizational factors influence energy management in school buildings, resulting in a complex situation away from the usual engineering approach. The selection of evaluation criteria to assess the energy performance of school buildings remains one of the most challenging aspects since these should accommodate the perspectives of the potential key stakeholders. This paper prese...
Evolutionary algorithms for building energy efficiency and end-use energy resou...
Gomes, Álvaro; Rodrigues, Eugénio; Soares, Ana; Henggeler Antunes, Carlos; Gaspar, AdélioThe first step for a rational use of energy in the building sector is to incorporate building performance concerns since the early design stage. This requires evaluation and exploration of alternative solutions. However, designers are unable to manually produce more than 2 or 3 solutions. Therefore, the combined use of computer generative methods, optimization techniques, and building performance simulation too...
Optimization of constructive systems through the application of a genetic algor...
Lopes, Nuno; Rodrigues, Eugénio; Gaspar, AdélioMultiple design features, such as form, construction material type and thickness, and glazing type and area, affect the building’s energy consumption. In this work, a procedure was developed to reduce the energy consumption of alternative building’s geometries by optimizing their constructive system elements. The optimization procedure consists of a genetic algorithm that seeks to improve the opaque elements’ m...
Control criteria of electrochromic glasses for energy savings in mediterranean ...
Tavares, Paulo; Bernardo, Hermano; Gaspar, Adélio; Martins, AntónioDuring the next decades the refurbishment of old buildings will be an essential way to contribute to the global improvement of buildings energy performance indicators. Within this context, the present paper is focused on the use of electrochromic (EC) windows, an emerging technology alternative to shading devices, to control solar gains in buildings located in Mediterranean climates. The optical properties adju...
Manual de Boas Práticas - Inovenergy
Andrade, Luís Pinto de; Nunes, José; Dinho, Pedro; Dinis, Pedro; Domingues, Luísa Catarina; Nobre, Telmo; Gaspar, Adélio; Feliciano, ManuelNos últimos 150 anos o clima tem-se tornado progressivamente instável e mais quente. Se nada for feito, estas alterações tendem a acentuar-se e afetarem negativamente o ambiente, com efeitos a nível dos recursos hídricos, das zonas costeiras, da agricultura, da saúde humana, da energia, e da biodiversidade. Estas alterações climáticas estão diretamente relacionadas com o crescimento das emissões dos Gases de Ef...

Occupational exposure to cold thermal environments: a field study in Portugal
Oliveira, A.; Gaspar, Adélio; Quintela, DivoAbstract The present work is essentially dedicated to the study of cold thermal environments. The analysis includes 32 industrial units from 6 activity sectors and the measurements were carried out in 101 workplaces. Different environmental conditions were identified and a clear relationship with the different types of workplaces was established. The work environments were thus allocated to three typical exposu...
