Hybrid ventilation is an effective means of minimizing ventilation energy and improving indoor environment. A scale experimental model with a heat source was created for hybrid buoyancy-driven natural ventilation with a mechanical exhaust system. The aim of this study is to examine the performance of hybrid ventilation in an industrial building. The temperature distributions and hybrid ventilation efficiencies with different mechanical exhaust velocities were analyzed. Results showed that the hybrid ventilation efficiency first increased and then decreased with the mechanical exhaust velocity. A critical mechanical exhaust velocity was identified and the hybrid ventilation efficiency reached maximum at the critical mechanical exhaust velocity. The critical mechanical exhaust velocity was 1.4 m/s at the heat flux of the heat source q = 200 W and 1.0 m/s at q = 500 W, and the corresponding ventilation efficiencies were 24.4 and 6.69, respectively. Four modes of hybrid ventilation were investigated, and ventilation strategies of different modes of hybrid ventilation were given. An excessive mechanical ventilation rate will cause consumption of ventilation energy to increase and may lead to short circuiting of airflow and a bad thermal environment. These results should prove helpful in designing of hybrid ventilation systems for industrial buildings.

The main goal is to create an appropriate spatial environment for the high-quality production of elements of folk art craft, while preserving the historical and aesthetic categories of products that ensure their recognition as a work of art.
The reuse of industrial buildings produces large amounts of construction dust, which poses significant health risks to construction workers. A dynamic health risk assessment (DHRA) framework is ...proposed to comprehensively estimate and reduce the hazards caused by dust produced during the renovation construction of polluted industrial buildings. The proposed framework primarily considers the changes in the construction process due to the changes in the temporal and spatial dimensions and is used to perform highly specialised risk assessments of dust hazards. The DHRA framework identified four time-varying factors: construction procedures, construction behaviours, site characteristics, and regeneration scenarios. In addition, the spatial distribution characteristics of dust and industrial pollutants produced through various construction processes were considered, and a spatio-temporal risk assessment model was developed to predict the degree of construction dust risk caused by construction behaviour. The DHRA framework expands the connotation of the United States Environmental Protection Agency (USEPA) model from a dynamic perspective and provides new ideas and methods for the occupational health and safety management of related construction projects. This framework can effectively promote the development of a sustainable theory. It can be used as a tool for predicting and assessing hazards, which can provide certain theoretical and technical references for dust control in various construction projects, especially in the reconstruction of old industrial buildings.

Industrial COsub.2 emission, accounting for nearly a quarter of the total COsub.2 emission, is a “hard-to-abate” emission sector, owing to the longstanding challenge in reducing COsub.2 emission ...while not sacrificing industry economics. Herein, this research proposes an integrated solar-driven COsub.2 capture system for application in industrial buildings to decarbonize factories’ COsub.2 -rich exhaust gas generated from workers or manufacturing processes, and further conducts multi-objective optimization based on the NSGA-II algorithm. By setting the integrated system’s performances, including captured COsub.2 mass, net levelized COsub.2 cost-profit, generated electricity, and exergy efficiency, as the constrained multi-objectives, the effects of system working parameters on them are disentangled and articulated concerning the energy-mass balance principles. Research demonstrates that the captured COsub.2 mass mainly depends on solar radiation and sorbent mass, net levelized COsub.2 cost on sorbent mass, and exergy efficiency on the total solar input. For capturing the COsub.2 from a light-COsub.2 -intensity factory with COsub.2 partial pressure of 1000 Pa by using 6.0 tons of Zeolite 13X, a COsub.2 capacity of 0.79 mol/kg, levelized COsub.2 cost of 128.4 USD/ton, and exergy efficiency of 5–10% can be achieved. Furthermore, sensitivity and scenario analysis are conducted to demonstrate the system’s stability and feasibility. Overall, this work provides comprehensive and objective-oriented guidance for policymakers and industry owners and paves the way for greening the ever-increasing industry needs.
The use of natural raw materials is today more significant in architecture than ever before. While timber construction is already firmly established in the field of architecture, there is an ...increasing focus on alternative construction materials such as clay, straw, cork or bamboo, along with their application features. In full alignment with sustainable construction, they make it possible to plan energy-optimised, recyclable and climate-friendly buildings for the future. The book shows how this can be achieved based on 30 projects of all sizes. The buildings present the entire spectrum of natural materials. They show numerous construction and application methods of the different building materials. This book manifests what is possible using natural construction materials in great detail.

•The interaction of the roof's horizontal diaphragm with the structural and non-structural elements influences the seismic behaviour of industrial buildings.•It was obtained a correlation between the ...stiffness required for a rigid behaviour at the roof level in terms of the shape of the building.•The consideration of a rigid diaphragm tends to produce a more realistic seismic behaviour of the overall structure.•The contribution of facade cladding wall panels significantly influences the seismic behaviour of the building, especially for high-rise buildings.
The seismic behaviour of precast reinforced concrete industrial structures has been extensively investigated in recent decades, especially after the damage caused by recent earthquakes. The interaction of the roof's horizontal diaphragm with the structural and non-structural elements can influence the seismic behaviour of these buildings. Thus, the present study aims to investigate this interaction, through nonlinear static and dynamic analyses using a simplified macro element to simulate the behaviour of cladding panels and an equivalent truss approach to simulate the roof in-plane stiffness. The analyses were performed on several structural models considering the current European single-storey precast reinforce concrete industrial building stock, with or without cladding wall panels, and with rigid or flexible diaphragm roof. Despite the uncertainties associated with the ability of common roof systems to ensure a rigid diaphragm, the analyses allowed the establishment of a correlation between the buildings generic properties and the roof horizontal stiffness required to approach a rigid diaphragm effect. In general, the results show that the consideration of a rigid diaphragm in numerical models may tend to produce a more realistic seismic behaviour of the overall structure. Furthermore, the contribution of facade cladding wall panels significantly influences the seismic behaviour of the building, especially for high-rise buildings.
