Comportamiento térmico de mampostería de bloques de yeso hidrófugo con variación del espesor de revestimiento
(Catholic University of the Most Holy Conception, 2020) José Reginaldo de Arruda Cavalcanti; Pedro Igor Bezerra Batista; Yêda Vieira Póvoas; Joaquín Humberto Aquino Rocha
The present research has the objective of analysing the influence of the ceramic coatings simulating the external side, and in gypsum, with different thicknesses, simulating the internal side of a masonry prototype of block seal of solid waterproof gypsum, seeking to improve the thermal performance mainly in the block joints of the block. For this, two specific test methods were used: the thermal chamber and the infrared thermography. We sought to analyse the temperature differences between the internal and external surfaces, by means of thermocouples connected in the middle of the prototype and the mapping of the temperature profile on the surface of the coating. It was verified that the addition of gypsum coatings plus ceramic improves the thermal performance of the sealing system. Noting that the thickness variation of gypsum mortar provides a gain in thermal resistance, reduction in thermal transmittance and gain in thermal capacity.
Estudo do desempenho térmico de uma edificação da POLI-UPE de acordo com a NBR 15575
(Faculdade Meridional (IMED), 2021) Hitalo José Tavares De Araújo; Pedro Igor Bezerra Batista; Yêda Vieira Póvoas; Joaquín Humberto Aquino Rocha
Esta pesquisa tem como objetivo verificar o método da simulação sugerido pela NBR 15575-1 como procedimento de qualificação do desempenho térmico de uma edificação. Para isso, foi adotada a edificação da portaria da Escola Politécnica da Universidade de Pernambuco que se localiza na cidade do Recife. A simulação foi efetuada com o software EnergyPlus. Buscou-se também comparar a temperatura do ar interno do cômodo da edificação de maior pico de temperatura, de acordo com os resultados da simulação, com medições in loco através do uso de sensor de temperatura. Os resultados mostraram que a desconsideração, pela simulação, das cargas internas que atuam na edificação, assim como a utilização apenas do valor máximo diário da temperatura do ar exterior para o dia típico de verão como critério, podem exercer considerável influência na qualificação do desempenho térmico de uma edificação.
Influence of Plaster Coating Thickness on the Thermal Behavior of Brick Masonry Walls

A ready-witted selection of high-quality construction materials for walls and roofs provides greater well-being and thermal comfort for building co-owners. It also reduces energy consumption with artificial conditioning appliances. This research aimed to analyze the thermal behavior of a ceramic brick masonry prototype composed of an external coating of Portland cement mortar and an internal plaster coating with variable thickness. Tests were carried out in a thermal chamber, and the temperatures were recorded by a non-contact thermographic camera and conduction thermocouples measuring equipment. Hence, the parameters obtained were fourfold: thermal resistance, thermal capacity, thermal transmittance, and thermal delay. The four latter were calculated as per the simplified method proposed in the Brazilian specification for Thermal performance in buildings (i.e., NBR 15220-1). As a result, the thicker plaster-coated block prototype showed a minor temperature variation during the heating process. Thus, the thickness of the plaster coating possesses a direct influence on the thermal response of the brick; The thicker the coating becomes, the better the thermal performance of the structural element.
Thermal Behaviour of Hydrofugated Plaster Block Masonry with Variation of Coating Thickness
(2024) José Reginaldo de Arruda Cavalcanti; Pedro Igor Bezerra Batista; Yêda Vieira Póvoas; Joaquín Humberto Aquino Rocha
The objective of this research is to analyze the influence of ceramic coating, simulating the external side, and plaster with different thicknesses, simulating the internal side of a prototype of solid water-repellent gypsum block masonry, aiming to improve the thermal performance mainly in the settlement joints of the block. For this purpose, two specific test methods were used: thermal camera and infrared thermography. The temperature differences between the internal and external faces were analyzed by means of thermocouples connected in the middle of the prototype and the mapping of the temperature profile on the surface of the cladding. It was found that the addition of gypsum sheathing plus ceramic improves the thermal performance of the masonry system, observing that the variation of the thickness of the gypsum mortar provides a gain in thermal resistance, a reduction in thermal transmittance and an increase in thermal capacity.
