“…Chow and Yu [84] studied the technique for determining OTTV. Using only one index of energy implementation, such as OTTV, might be insufficient to produce a power-saving as well as cost-efficient building design [85].…”

Automation, modernization, economic development and global progress depends on efficient extraction and utilization of energy. Power generation by burning fossil fuels makes various adverse impacts on the environment. Additionally, the worldwide fossil fuel reserve is limited and depleting very fast. Hence, efficient energy usage and savings are crucial to address the environmental issues to ensure sustainable development. Buildings, both commercial and residential, represent a major energy consumption sector. Approximately 40% of the total energy is reportedly consumed in the building sector. Worldwide building energy consumption, performance measuring systems and best practices, energy-saving techniques and policies are reviewed and summarized in this article. Underfloor air distribution, double-glazed windows, use of highly efficient electric motors and variable speed drives may play a great role in reducing building energy consumption. In the UK, the application of double-glazed windows in commercial buildings can save 39–53% energy. The proper maintenance of a building’s central heating system can save up to 11% energy. The automatic HVAC control system can reduce up to 20% of the building’s total heating load. Proper utilization of a VSD system in motor and building performance optimization by an ANOVA tool also proved instrumental in saving energy. Apart from this, the building codes of different countries also help to improve building performance by reducing energy consumption. This study will help building researchers and policymakers to make a framework for sustainable, green building.

“…The outbreak of fires from various causes, including carelessness, arson, and terrorism, underscores the urgency of prioritizing compartment fire safety and enhancing fire and rescue services for better dealing with post-flashover building fires. Thermally insulated buildings with lower Overall Thermal Transfer Values [1][2][3] will have a shorter time to flashover. A substantial challenge for the fire and rescue services represents their capacity to keep up with the times and, in case of need, to have the opportunity for quick and timely reconfiguration of their activities in response to the changing conditions.…”

The reconfiguration of fire and rescue services is the focus of this research. The main purpose is to propose an alternative organizational model for better dealing with post-flashover building fires. The primary source of empirical information is a survey involving 267 managers from the Bulgarian fire and rescue services to gather insights. The research methodology meticulously encompasses the identification of changes concerning the efficiency and effectiveness of the fire and rescue services, the discernment of inherent challenges, the definition of specific factors and criteria relevant to their activities, and the determination of strategic priorities. The goal is to suggest a new, more efficient way to organize these services in Bulgaria, whose approach can be applicable to other contexts in similar conditions as well. The proposed model suggests that the Bulgarian fire and rescue services should work independently from the Ministry of Interior as the State Agency under the Council of Ministers. In addition, a comparison between this newly proposed model and the current one is conducted to highlight its potential advantages.

This Paper studies the shape of high-thermal insulating concrete tiles used for roof tiling. The theoretical part consists of a comparison between this invented tiles and ordinary terrazzo tiles. The analysis depends on the values of thermal conductivity of the material used. The results showed that when these tiles are used for roof tiling, the temperature difference between the outside of roof surface and the inside room can be reduced about six times compared with the use of ordinary terrazzo tiles. In addition, these specimens were fabricated and tested for rupture and absorption tests. The test results showed that, they had a good resistance to the applied test loads, and high resistance to water absorption. The authors believe that, the results are remarkable, highly applicable and should be taken into consideration in building constructions.
