Data of temperature and relative humidity in a historic library in Portugal
Schito, Eva; Pereira, Luísa Dias; Testi, Daniele; Silva, Manuel Carlos Gameiro daThe correct preservation of old and rare books in libraries needs suitable values of temperature and relative humidity. This paper shows the hygrothermal data acquired in a historic library, the Baroque Library, of the University of Coimbra, Portugal, where several old and rare books are stored. The data were acquired during a 6-month monitoring campaign. In particular, in this paper the spatial and temporal va...
Ocular risks assessment in a central receiver solar power facility based on mea...
Rascón, Danyela Samaniego; Ferreira, Almerindo Domingues; Silva, Manuel Carlos Gameiro da; Iriarte, CuitlahuacAmong the Concentrated Solar Power technologies, central receiver systems (CRS) is the technology moving to the forefront in market penetration. CRS requires the use of heliostats oriented toward the central receiver in order to concentrate solar radiation. The excess of light due to the reflection of the sunlight on the heliostats' surface and the brightness of the receiver are considered as possible situation...
An integrated approach on energy consumption and indoor environmental quality p...
Pereira, Luísa Dias; Neto, Luis; Bernardo, Hermano; Silva, Manuel Carlos Gameiro daThis work is part of a wider research project called Energy Efficient Schools (Escolas Energeticamente Eficientes, 3Es), granted by Teixeira Duarte in the framework of the Portuguese Program of R&D Projects associated with Large Public Tenders. The authors are thankful to Parque Escolar E.P.E. for the provision of the database on the Portuguese secondary schools. The presented work is framed under the Energy fo...
Estimation of classrooms occupancy using a multi-layer perceptron
Rodrigues, Eugénio; Pereira, Luísa Dias; Gaspar, Adélio Rodrigues; Gomes, Álvaro; Silva, Manuel Carlos Gameiro daThis paper presents a multi-layer perceptron model for the estimation of classrooms number of occupants from sensed indoor environmental data-relative humidity, air temperature, and carbon dioxide concentration. The modelling datasets were collected from two classrooms in the Secondary School of Pombal, Portugal. The number of occupants and occupation periods were obtained from class attendance reports. However...
Development of a new CO2-based Demand-controlled Ventilation Strategy Using Ene...
Chenari, Behrang; Lamas, Francisco Bispo; Gaspar, Adélio Rodrigues; Silva, Manuel Carlos Gameiro daA significant amount of energy is being used by ventilation and air conditioning systems to maintain the indoor environmental condition in a satisfactory and comfortable level. Many buildings, either new or existing (throughout their renovation process) are subjected to energy efficiency requirements but these must not be in the expenses of indoor environmental conditions. For instance, indoor air quality (IAQ)...

Pereira, Luisa Dias; Carrilho, João; Brito, Nelson da Silva; Gomes, Maria de Fátima Teixeira Rocheta; Mateus, Mário; Chenari, BehrangThe first five authors express their gratitude to FCT for partially supporting their research projects through the Ph.D. research grants, SFRH/BD/77105/2011, SFRH/BD/77911/2011, SFRH/BD/51017/2010, PD/BD/105844/2014, and SFRH/BD/37828/2007, respectively. The sixth author was supported by the Smart Window project CENTRO-07-0202-FEDER-03412. The 3Es project was funded by the company Teixeira Duarte on the framewo...
Indoor air quality audit and evaluation on thermal comfort in a school in Portugal
Pereira, Luísa Dias; Cardoso, Edna; Silva, Manuel Carlos Gameiro daGiven the Portuguese national programme for rehabilitation of school buildings and the new regulations for thermal comfort and air quality in Portugal, whose demands contribute to increase energy costs, it became relevant to study a case before any refurbishment intervention, in order to assess the potential of different methods of actions and to improve results. It was also intended with this study to evaluate...
Improving Energy Efficiency and Cost Reduction in Airports: Contributions from ...
Pereira, Luísa Dias; Botte, Gustavo; Soares, Miguel; Silva, Manuel Carlos Gameiro daIn the present case study – an airport located at the southern region of Portugal with an increasing number of passengers (more than 5.7 million passengers) - a web-based monitoring system was installed, collecting, displaying and registering the information generated by a wireless network of sensors. The monitoring of indoor environmental quality parameters, along with billed energy data control and outdoor we...
