Lillebø, Ana; Disterheft, Antje; Curado, António; Loureiro, António; Santos, Joaquim; Sousa, José Luís; Alves, Júlia; Neves, Luis; Barros, ManuelO presente número especial resulta da 6.ª edição da Conferência Campus Sustentável (CCS2024), organizada pela Universidade de Aveiro e promovida anualmente pela Rede Campus Sustentável, sob o tema “Ações transformativas da academia com a sociedade para implementação dos Objetivos de Desenvolvimento Sustentável”. Este volume reúne contributos que refletem o objetivo da conferência: mobilizar conhecimento, prátic...
Designing a Multicriteria WebGIS-Based Pre-Diagnosis Tool for Indoor Radon Pote...
Nunes, Leonel; Curado, António; Azevedo, Rolando; Silva, Joaquim P.; Lopes, Nuno; Lopes, Sérgio IvanRadon (222Rn) is a well-known source of indoor air contamination since in its gaseous form it is a reported source of ionizing radiation that belongs to the group of rare gases. Radon occurs naturally in soils and rocks and results from the radioactive decay of its longer-lived progenitors, i.e., radium, uranium, and thorium. Radon releases itself from the soil and rocks, which mainly occurs in outdoor environm...
A pre-diagnosis model for radon potential evaluation in buildings: A tool for b...
Silva, Joaquim; Lopes, Nuno; Curado, António; Nunes, Leonel J R; Lopes, Sérgio IvanIn a very early stage of implementation of a comprehensive experimental campaign for indoor radon assessment, a pre-evaluation selection of the variables that play a leading role in influencing expected results must be insightfully assessed, by stimulating compatibility between Indoor Air Quality (IAQ) and energy efficiency. Hence, a practical methodology for variable selection based on an analysis of historic ...
Towards Indoor Radon Analytics: An OLAP-based Multidimensional Approach
Azevedo, Rolando; Silva, Joaquim P.; Lopes, Nuno; Curado, António; Nunes, Leonel J R; Lopes, Sérgio IvanIndoor radon represents a known hazard to public health, namely, its relationship with lung cancer. The adoption of data analytics tools for indoor radon human exposure risk assessment is crucial for building management decision-making and is a fundamental requirement for the implementation of remediation measures. This work presents the implementation of a data warehouse and an OLAP cube as components of a mor...
Designing an IoT-enabled Data Warehouse for Indoor Radon Time Series Analytics
Azevedo, Rolando; Silva, Joaquim P.; Lopes, Nuno; Curado, António; Nunes, Leonel J R; Lopes, Sérgio IRecently we have seen an increase in the frequency of radon concentration measurement campaigns, largely driven by directives adopted at a European level, and by increased public awareness of the problem. Many of the conducted assessments are simple concentration averages over a time range, where passive sensors are mostly used. Other assessments use portable devices that measure radon in a continuous mode, whi...
Indoor Radon Remediation in Highly Constrained Built Environments: Balancing In...
Curado, António; Nunes, Leonel J R; Silva, Joaquim P; Lopes, Nuno; Azevedo, Rolando; Lopes, Sérgio IvanEnergy Efficiency (EE) and Indoor Air Quality (IAQ) are mandatory features in the rehabilitation of historical buildings. Even though it is challenging to manage both sides, EE demands are fundamental to increasing buildings´ thermal comfort, and IAQ requirements are essential for improving occupants’ wellness. There are, however, several constraints that limit the intervention in complex buildings, such as the...
Designing a qualitative pre-diagnosis model for the evaluation of radon potenti...
Silva, Joaquim P.; Lopes, Nuno; Curado, António; Nunes, Leonel J R; Lopes, Sérgio IIn a very early stage of implementation of a comprehensive experimental campaign for indoor radon assessment, a pre-evaluation selection of the variables that play a leading role in influencing expected results must be insightfully assessed. Hence, a practical methodology for variable selection based on an analysis of historic data plays a key role concerning radon potential assessment. Given the circumstances,...
The impact of daylight saving time on the energy efficiency of buildings: a bib...
Araújo, Ivo; Nunes, Leonel J. R.; Patíño Vilas, David; Curado, AntónioThe absence of standardized time zones has profound implications, influencing social, economic, and energy dynamics. It also disrupts personal aspects, such as sleep patterns and family routines. One specific dimension of this issue is the transition to daylight saving time (DST), which entails shifting between standard time (winter) and daylight saving time (summer). This practice has sparked global debates du...
Impact of daylight saving time on energy consumption in higher education instit...
Araújo, Ivo; Garcia, João; Curado, AntónioDaylight Saving Time (DST), involving clock shifts forward in spring and backward in autumn, was introduced to promote energy savings. However, its effectiveness remains controversial, especially in buildings with temporary occupancy like academic institutions, which have high daytime use but low summer occupancy. This study investigates the impact of DST transitions on energy consumption across seven campuses ...
The harmonization of radon exposure mitigation for the sustainability of buildi...
Nunes, Leonel J. R.; Curado, AntónioRadon exposure is a major health concern associated with an increased risk of lung cancer, particularly in smokers, highlighting the need for effective mitigation measures in enclosed spaces by improving indoor air quality (IAQ), thus ensuring more sustainable buildings. The Euratom Directive, a key piece of EU legislation, sets standards for the protection of workers and the general public from ionizing radiat...
