The development of energy-efficient and sustainable building materials is imperative to reduce energy consumption in the construction sector. This study addresses both the applied problem of increased solar heat gain and decreased indoor thermal comfort, as well as the scientific problem of reducing the thermal conductivity of clay bricks. It investigates the incorporation of recycled spent mushroom materials, consisting of Pleurotus florida mycelia and rice husk waste, as a novel additive in the production of fired clay bricks (FCBs) to enhance thermal insulation properties. The developed bricks were utilized in an optimized wall design for a residential building in New Cairo, Egypt. The wall design is created using energy modeling software, including Honeybee, Ladybug, Climate Studio, and Galapagos. The results demonstrate that an optimal waste content of 15% and a firing temperature of 900 °C yield the best thermal performance. Compared to traditional FCB walls, the new design incorporating the florida waste additive significantly improves thermal comfort, as indicated by a lower predicted mean vote and predicted percentage of dissatisfaction. Furthermore, the developed walls contribute to a reduction in CO2 emissions of 6% and a decrease in total energy consumption of 38.8%. The incorporation of recycled florida waste offers a sustainable approach to enhancing standard brick fabrication processes. This work highlights the promise of agricultural waste valuation for the development of eco-friendly and energy-efficient building materials. Future research should explore the mechanical strength, acoustics, cost–benefit analysis, and field implementation of the developed walls, thereby addressing both the scientific and applied aspects of the problem.

Los edificios son uno de los principales actores contaminantes del medio ambiente, por lo que es necesario fortalecer las estrategias para la reducción de su consumo energético, como el diseño energéticamente eficiente (edificios nuevos) y la gestión energética (edificios existentes). Para ello, es fundamental la predicción del consumo energético que permita conocer el estado de operación de la edificación e inferir sobre las causas de éste y la eficacia de las estrategias de ahorro energético. No obstante, la diversidad de técnicas de predicción del consumo energético existentes dificulta a investigadores su identificación, selección y aplicación. Por ello, a partir de una revisión de la literatura, este artículo identifica técnicas de predicción, expone sus principios teóricos, describe las etapas generales de construcción de un modelo de predicción, reconoce métricas de evaluación, identifica algunas de sus fortalezas y debilidades y presenta criterios para facilitar la selección de una técnica de predicción y métricas de evaluación según las características del caso de estudio. Se realizó un análisis bibliométrico como metodología para identificar y estudiar los artículos más importantes sobre demanda de energía en edificios. Se encuentra que hay tendencia en la aplicación de técnicas de aprendizaje automático y que los modelos de predicción de consumo energético son mayormente aplicados a edificaciones residenciales, comerciales y educativas.

“…Energy saving remains a vital issue for decades in the times of increasing environmental problems. Around 30% to 40% of the world's energy consumption is produced by the building sector in preserving comfortable indoor state and to supply power for the electrical devices [1][2][3][4][5][6][7][8]. Consequently, this has led to the increase of energy usage and Greenhouse gas (GHG) emission.…”

Thermal comfort is a subjective response that reflects the contentment between one’s state of mind and the current environment. The energy consumption of the building sector has rapidly increased due to improved living standards and rising expectations of residents regarding thermal comfort. Mechanical ventilation, especially air conditioning systems, is essential for hot and humid countries aiming to achieve an ideal indoor comfort condition. However, such cooling systems often consume a significant amount of electricity, which contradicts the concept of energy conservation. Therefore, thermal comfort assessment is a method that can be employed to address this issue. Evaluating the thermal perception of occupants can subsequently facilitate more efficient electricity usage, aligning with the goal of energy conservation. In this study, a thermal comfort analysis was conducted on free-running residential buildings in Sarawak. These buildings were naturally ventilated with minimal use of mechanical ventilation systems. Physical measurements and subjective assessments were employed to evaluate the thermal responses of the residents based on various sensation and comfort scales, including the ASHRAE scale, Bedford scale, thermal acceptability scale, and thermal preference scale. Additionally, the widely used PMV model was utilized to predict the thermal sensation experienced by the residents. The results of the study indicated that the Bedford scale exhibited the highest percentage of acceptable responses, followed by the ASHRAE scale, thermal acceptability scale, and thermal preference scale. The PMV model was observed to overpredict the residents’ thermal responses. The comfort temperatures derived from the study were 27.5 ∘C, 28.1 ∘C, and 26.2 ∘C according to the ASHRAE scale, Bedford scale, and PMV model, respectively. Based on the actual percentage of dissatisfaction that ensures 80% satisfaction, the acceptable indoor temperature range was found to be 27.3 ∘C to 29.6 ∘C. Similarly, the acceptable range for relative humidity was 74.0% to 92.0%, and for air velocity, it was 0.18 m/s to 0.66 m/s. Keywords: thermal comfort, thermal perception, sensation, comfort scales
