The development of bio-insultation materials has attracted increasing attention in building energy-saving fields. In tropical and hot–humid climates, building envelope insulation is important for an energy efficient and comfortable indoor environment. In this study, several experiments were carried out on a bio-insulation material, which was prepared by using rice husk as a raw material. Square rice husk-based insultation panels were developed, considering the ASTM C-177 dimensions, to perform thermal conductivity coefficient tests. The thermal conductivity coefficient obtained was 0.073 W/(m K), which is in the range of conventional thermal insulators. In a second phase of this study, two experimental enclosures (chambers) were constructed, one with rice husk-based insulation panels and the second one without this insulation. The measures of the temperatures and thermal flows through the chambers were obtained with an electronic module based on the ARDUINO platform. This module consisted of three DS18B20 temperature sensors and four Peltier plates. Daily temperature and heat flux data were collected for the two chambers during the dry season in Panama, specifically between April and May. In the experimental chamber that did not have rice husk panel insulation on the roof, a flow of up to 28.18 W/m2 was observed, while in the chamber that did have rice husk panels, the presence of a flow toward the interior was rarely observed. The rice husk-based insulation panels showed comparable performance with conventional insulators, as a sustainable solution that takes advantage of a local resource to improve thermal comfort and the reduction of the environmental impact.

“…Efficient buildings are needed to contribute to sustainable development. In line with these needs, countries have adopted specific approaches and regulations linked to net zero energy targets (De León et al, 2023). Reducing GHG emissions and promoting sustainable development are two major goals of the NZEB concept.…”

In this study, the energy performance analysis of a representative residential building located in Izmir, Turkey, was carried out, utilizing the DesignBuilder energy simulation program. Heating, ventilation, and air conditioning systems are modeled as detailed in Design Builder in order to consider parameters such as thermal properties of materials, duct layout and airflow dynamics of the system in detail in the analysis. The technical and economic analysis of transforming the building into a nearly zero energy building (NZEB) was performed for eight different retrofit scenarios, including passive and active energy efficiency measures. The most effective scenario, Scenario 8 (S8), reduced the building's annual net primary energy consumption by 96.08% to 7.45 kWh/m²/year. S8's annual CO2emissions decreased by 100.07% compared with the reference scenario, resulting in −0.042 kg CO2/m²/year. The overall energy performance class of the building was determined using Turkey's national calculation program for the preparation of the energy identity certificate. The energy performance class of the reference building was determined as D, and the class of the building designed according to S8 as A. Investment evaluations were carried out for the retrofit scenarios, revealing that the investment cost for S8, having the lowest net primary energy consumption, amounted to USD 17,565.87. This finding establishes S8 as a more financially viable option in the short term. This study demonstrates the potential of NZEBs in reducing greenhouse gas emissions and achieving sustainable development goals.

“…Há necessidade de intensificação da pesquisa de documentos regulatórios que se adequem a cada tipo de clima e condições socioeconômicas e culturais, especialmente em lugares de pobreza energética. Por exemplo, independência de resfriamento mecânico (ar-condicionado) significaria diminuição de consumo de energia até 40% [16]. Desenvolvimento das estratégias passivas na escala de bairro/distrito poderiam servir para otimização de consumo de energia e ao mesmo tempo otimização de investimentos iniciais no projeto de Distrito de Balanço Energético Nulo.…”

Neste artigo é apresentada a evolução do conceito de Distrito de Balanço Energético Nulo, termo intitulado em literatura inglesa Zero-Energy District, a partir de revisão bibliográfica em três bases de dados para artigos publicados entre 2017 e 2022. Destacam-se os fatores principais que determinam a emergência dos termos derivados deste conceito: Distrito de Balanço Energético Quase Nulo (Nearly Zero-Energy District), Distrito de Balanço Energético Nulo Líquida (Net Zero-Energy District), Distrito de Balanço Energético Positivo (Positive Energy District), Comunidade de Balanço Energético Nulo (Zero-Energy Community). Como conclusão, aponta-se a necessidade de transferir os conceitos associados aos Distritos de Balanço Energético Nulo e adaptar normas já implantadas em países desenvolvidos a realidade dos países do Sul Global.
