Background: Concrete buildings on Guam are exceptionally strong but also accumulate large amounts of heat. In the tropical environment of Guam, where 24 h average temperature ranges from 28 to 29oC year round, air conditioning is used every day and continuously. Concrete roofs are often painted light colors, which make them more reflective and accumulate less heat. They are also suitable for es...

Sustainable building practices can considerably reduce building’s environmental impact in energy consumption. Covering a building envelope with green vegetation, such as green roof and green wall, is considered a sustainable construction practice, as green vegetation has a positive performance in energy savings. It reduces heat flux and solar reflectivity, generates evaporative cooling, increas...

Youth gangs are on the rise. Today they threaten virtually every major city, many small communities, and even rural areas. The Office of Juvenile Justice and Delinquency Prevention (OJJDP) is committed to helping communities overcome this problem, and an essential first step is understanding the factors that contribute to the growth of youth gangs and the relationship of gang membership to deli...

Damages such as rising and cracking due to enlargement growth of roots are quite often observed in the components such as path pavements, curbs, retaining walls and garden furniture on green roof. To avoid the defects, root resistance of those components used for green roof should be estimated by a suitable test before actual applications of them. In this study a test apparatus and a test metho...

Green roofs are considered to be one of the optimal tools for saving energy and protecting environment in developed countries. In this paper, an analysis possible application green on existing residential buildings with flat is presented. economic analysis, models Belgrade, two different types roofs, studied. A key indicator investment profitability investigation net present value (NPV) roof pr...

Saudi Arabia is one of the largest countries in the Middle East region in terms of population, geographic area and scale of economy. It has a fast growing energy sector with over 76% of the total electricity being consumed in the building sector. Domestic buildings account for 51% of total electricity consumption. Predominantly due to hot climatic conditions, most of the energy consumption in b...

To reduce the impact of climate change in form low-carbon developments, innovations sustainable building strategies are imperative. In this regard, performance a double-roof house consisting photovoltaic panel roof (PV) and green (GR) was compared to traditional solar-roof buildings. The synergy between both PV GR systems analysed by numerical simulations physical modelling across four seasons....
