Considerations on the determination of measurements uncertainties values in laboratory airborne sound insulations measurements

Antunes, S.; Patrício, J.; Antonio, J.-; Falcão, A. (Sociedade Coreana de Acústica, 2020-08-23)

Due to the publication of the latest edition of ISO / IEC 17025 (2017 edition), the presentation of measurement uncertainty values associated with sound insulation tests, becomes an important requirement. Taking into account ...
Experimental assessment of building-façade kits and constituent materials

Real, L. P.; Pina dos Santos, C. (Conference Era, 2019-05-13)

Biocomposites, containing biopolymers and/or natural fibres, are sustainable and environmentally friendly construction materials and have lower energy incorporated than conventional materials traditionally used by the ...
Experimental assessement of biocomposites and nanoinsulation materials at macro scale for next generation building-façade systems

Real, L. P. (Phronesis, 2019-06-11)

The construction sector has a key role to play in achieving the global objectives of sustainable development. At the request of society and consumers, there is a growing incentive to use sustainable and environmentally ...
Assessment of vibrations and structural noise at environmental impact studies: Current practices in Portugal and aspects to be improved for railway traffic in tunnels

Patrício, J.; Antunes, S. (International Commission for Acoustics (ICA), 2019-09-11)

Currently there is no consensus for the assessment of the human response to indoor vibrations. Also, the methodology used by several countries is different, as can be seen from the publication and use of different normative ...
Increasing water and energy efficiency in university buildings: a case study

Rodrigues, F.; Afonso, A.; Pinto, A.; Macedo, J.; Santos, A.; Rodrigues, C. (Springer, 2019-04-15)

Nowadays, humanity is consuming unsustainably the planet’s resources. In the scope of energy resource consumption, e.g., the intense use of fossil fuels has contributed to the acceleration of climate changes on the planet, ...
Enhancement of heat transfer in office buildings during night cooling − reduced scale experimentation

Lança, M.; Coelho, P.; Viegas, J. (Assembly of World Conferences on Experimental Heat Transfer, Fluid Mechanics and Thermodynamics, 2017-06-12)

Most office buildings are designed to be ventilated and cooled using mechanical systems. In a temperate climate, when the outdoor temperatures are favourable, e.g. at night, passive ventilation and cooling techniques can ...
Mechanical behaviour of ventilated cladding kits: Experimental and numerical assessment

Tamen, D.; Pinto, A.; Reis, L. (IST, 2018-07-17)

Cladding systems are often used in rehabilitation of buildings to increase the thermal insulation of wall and also to increase the water tightness of walls and to improve the architectural aesthetics. These systems are ...
Evaluating the degree of gelation of PVC-U pipes. Comparison of currently available methods

Real, L. P.; João, I.; Pimenta, S.; Diogo, H. (ELSEVIER, 2018-09-01)

Health and Safety policies have led to the recommendation of alternative tests to evaluate the resistance to dichloromethane to estimate the degree of gelation of rigid PVC pipes (PVC-U). In this work, we confirm that DSC ...
Comparative study on the efficiency of impact sound reduction provided by same materials when disposed on homogeneous and on non-homogeneous floors

Alonso, A.; Patrício, J. (European Acoustics Association (EAA), 2018-05-28)

From the acoustical point of view, the main purpose of floor coverings and/or floating floors is to reduce the impact noise of the bare floor, in order to normally comply with national regulations. It is widely known that ...
Estratégias de reabilitação de vãos envidraçados exteriores

Batista, I.; Pinto, A.; Cachim, P.; Velosa, A. (Universidade de Aveiro, 2017-06-29)

O edificado é responsável por uma percentagem significativa do consumo de energia associado ao conforto térmico no seu interior. A eficiência energética dos edifícios não se restringe apenas aos novos edifícios, mas também ...
Analysis of the perceived thermal comfort in a portuguese secondary school: Methodology and results

Laborda, M.; Pinto, A.; Acosta, I.; Muñoz-Gozález, C. (International Journal of Engineering and Technology, 2017-12-06)

Abstract—This paper presents a methodology to assess the thermal environment in nonuniversity classrooms, using the example of the results obtained from a multipurpose classroom of a Portuguese secondary school during a ...
Método de avaliação da vulnerabilidade às alterações climáticas de hotéis: Hotel adptation tracker

Pinto, A.; Rogeiro, J.; Martins, R.; Santos, A.; Machado, P.; Santo, F.; Oliveira, A.; Silva, A. (iiSBE, 2017-11-17)

As alterações climáticas (AC) e o aumento da frequência de fenómenos extremos podem afetar o setor do turismo se as suas infraestruturas não estiverem adaptadas e não forem resilientes. Por exemplo, às ondas de calor estão ...
Avaliação de modelos de simulação de sistemas PV para edifícios no contexto nZEB

Santos, A.; Pinto, A. (iiSBE, 2017-11-16)

No âmbito da certificação energética de edifícios (REH ou RECS) a componente renovável dos sistemas fotovoltaicos (PV) é avaliada com o software SCE.ER, que não é uma ferramenta de projeto e por outro lado não permite uma ...
LCA of three structural solutions of a building in the University of Aveiro

Aljundi, K.; Rodrigues, F.; Pinto, A.; Reis, C. (iiSBE, 2017-11-16)
