“…However, no studies discussing the thermal performance (thermal Resistance Rt [m 2 .K.W -1 ], or Thermal Transmittance U [W. (m 2 .K) -1 ] (ABNT, 2003) of PETBs a.r panel has been found. The following publications on thermal performance ought to be highlighted due to their similarities to the aim of this study (Laurenti et al, 2003;Ha et al, 2022;Bienvenido-Huertas et al, 2020;Peng and Wu, 2008;Jorge, 2011).…”

This study aims to investigate the influence of PET bottle type used during PET panel manufacturing on their thermal performance. Used PETBs are an increasing threat to the environment. Plastic wastes cause air pollution, and water and soil contamination. Nowadays, vast amounts of such waste are unsafely disposed of in Brazil. The reuse of PETBs for PET panel manufacturing may contribute to minimizing or eliminating their recycling costs and reduce solid waste pollution. The classification and characterization of the most frequently commercialized PETBs were carried out. A PET panel prototype, adjustable to the PETB types most commonly used in Brazil, was designed and built. The influence of PETB type on PET panels' thermal performance was evaluated by measuring the PET panel prototype's equivalent thermal resistance with an unfilled air chamber and with the air chamber filled with 5-, 2-, 1-, and 0.5-L PETBs, respectively. The null hypothesis, which corresponds to the equal variability between the equivalent thermal resistance for the filled and unfilled PET panel prototype's air chamber, was tested. F-tests were used. The Null hypothesis for 5-L PETB may be accepted and rejected for 2-, 1-, and 0.5-L PETBs. The thermal transmittance of PETB panels manufactured with all PETB types included in this work meets the requirements established by law for any Brazilian bioclimatic subzone.

“…Depending on the energy system, there are many existing characterization techniques [ 40 ]. For building envelope characterization, several industrial and experimental methods have also been developed [ 41 , 42 , 43 ]. Nevertheless, most methods were too specific and costly for our research project.…”

This article outlines the implementation and use of a large wireless instrumentation solution to collect data over a long time period of a few years for three collective residential buildings. The sensor network consists of a variety of 179 sensors deployed in building common areas and in apartments to monitor energy consumption, indoor environmental quality, and local meteorological conditions. The collected data are used and analyzed to assess the building performance in terms of energy consumption and indoor environmental quality following major renovation operations on the buildings. Observations from the collected data show energy consumption of the renovated buildings in agreement with expected energy savings calculated by an engineering office, many different occupancy patterns mainly related to the professional situation of the households, and seasonal variation in window opening rates. The monitoring was also able to detect some deficiencies in the energy management. Indeed, the data reveal the absence of time-of-day-dependent heating load control and higher than expected indoor temperatures because of a lack of occupant awareness on energy savings, thermal comfort, and the new technologies installed during the renovation such as thermostatic valves on the heaters. Lastly, we also provide feedback on the performed sensor network from the experiment design and choice of measured quantities to data communication, through the sensors’ technological choices, implementation, calibration, and maintenance.
