Use of passive cooling techniques and super cool materials to minimize cooling energy and improve thermal comfort in Brazilian schools

Energy and Buildings, Journal Year: 2024, Volume and Issue: 312, P. 114125 - 114125

Published: April 26, 2024

Standardized replicable buildings can cause discomfort and increased air conditioning usage. Besides, super cool coatings are effective passive solutions. Therefore, this study evaluates thermal comfort in a standardized Brazilian public school 8 climates, verifies suitable identifies optimal additional techniques to meet regulatory requirements without active conditioning, topic worthy of investigation. Methods include pilot simulations with DesignBuilder, analysis considering ASHRAE 55 adaptive model; JEA Algorithm optimization simulations; identification most influential strategies by sensitivity analyses; evaluation the ideal opaque envelope through heat balance. Results showed that current model do not normative. Thus, different recommended: thermochromic for heating-dominated; spectrally selective cooling-dominated dry high broadband emissivity extreme-cooling-dominated humid zones. Regarding envelope, mass flat roofs insulated walls advised. In 7 roof was followed natural ventilation. Optimal combinations window shading ventilation 24 hours days week 95 % free-aperture zones; roofs, medium reflectivity 5 cooling-dominated; dark during occupancy heating-dominated.

Development of climate zones for passive cooling techniques in the hot and humid climate of Indonesia

Building and Environment, Journal Year: 2022, Volume and Issue: 226, P. 109698 - 109698

Published: Oct. 13, 2022

The classification of climate zones is required for developing appropriate predesign strategies energy-efficient buildings. Standardized hourly climatic data from 2014 to 2020, including global horizontal irradiance, air temperature, wind speed, relative humidity, precipitation, atmospheric pressure, total cloud cover, and mixing ratio, collected 106 sites were used zoning in Indonesia. First, the temperature containing four area divisions determined obtain statistical patterns diurnal seasonal temperature. comfort ventilation potential was assessed based on a using combination speed characteristics, while evaporative cooling humidity characteristics. Total hours showed (daytime nighttime) changes. Second, eight integrated namely, equatorial, sub-equatorial, highland tropical, very monsoonal, sub-monsoonal, savanna, sub-savanna, principal component analysis, cluster spatial interpolation methods. Third, calculation degree days loads followed by potentials night ventilation, carried out each zone. For example, taking lower probability limit 50%, sub-savanna found be suitable Meanwhile, sub-equatorial zone applying passive methods combining ventilation.

Exploring the Common Ground of Sustainability and Resilience in the Building Sector: A Systematic Literature Review and Analysis of Building Rating Systems

Sustainability, Journal Year: 2023, Volume and Issue: 15(1), P. 884 - 884

Published: Jan. 3, 2023

Over the last ten years, due to increase in frequency and severity of climate change effects, resilience buildings has become a growing topic current global discussion on adaptation. Designing both sustainable resilient constructions would help face such effects; however, sustainability design have been mostly treated separately so far. Since considered more than resilience, paying deeper attention latter is indispensable reducing building vulnerability. The purpose this article examine commonalities between using two different approaches: (i) systematic literature review, taking into consideration 10-year period for selecting records, (ii) an analysis five green rating systems guidelines selected according their popularity number certified buildings. There overlap some indicators domains at level, as shown by results from paths. These aspects could assist considering very beginning process. This will ensure that may be designed effectively enhancing synergies domains. paper targets potential stakeholders who interested including integrated implementation designs.

Published: Feb. 26, 2025

Modular construction provides numerous benefits over traditional methods, especially when combined with digital technologies, offering a faster, safer, leaner, and more sustainable environment. This literature review follows the PRISMA method to assess recent advancements in digital-oriented modular towards climate-neutral built environment, identifying research trends gaps based on three pillars: tools, building solutions, environmental sustainability. examines integration of technologies extending analysis circular bioclimatic efforts, renewable energy sources, passive design strategies. While most articles focus BIM uses, there is an increasing emphasis IoT applications that leverage real-time data achieve sustainability goals. However, no full-scale automated Digital Twin was found this context. Additionally, Building Energy Modelling (BEM) Life Cycle Assessment (LCA) tools are frequently discussed, reflecting push for climate-friendly housing. Despite interest parametric generative design, machine learning artificial intelligence strategies remains underexplored. Only few papers acknowledged reaching nZEB requirements despite great solutions sources contribute goal. material circularity has yet its full potential construction. Moreover, some off-grid buildings, although further should be undertaken analyse feasibility communities. Furthermore, findings highlight digitalisation enhance efficiency ensure within Architecture, Engineering, Construction (AEC) sector.
