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...

Abstract Arrays of buildings with pitched roofs are common in urban and suburban areas European cities. Large-eddy simulations performed to predict the boundary-layer flows over flat pitched-roof cuboids gain a greater understanding impact on boundary layers. The simulation methodology is validated for an array roof cuboids. Further show that changes type grid conformity have negligible effect ...

As essential elements of buildings, roofs traditionally correspond to about 3-8% of total project cost. Despite this considerable share, in the literature there have been only a few researches that investigate roof types preferred by owners/designers and make a cost analysis to reveal cost differences between alternatives. Toward this aim, in this study, twelve types of roofs installed in const...

A transient heat transfer mathematical model for the prediction of temperature distribution in the car body during primer baking has been developed by considering the thermal radiation and convection in the furnace chamber and transient heat conduction governing equations in the car framework. The car cockpit is considered like a structure with six flat plates, four vertical plates representing...

The development of BIPV technology and their implementation in construction of building envelop provides an aesthetical, economical and technical solution. This paper presents the building envelope products, and their properties. BIPV products for pitched roof, flat and curved roof, transparent and semitransparent facades and skylights have been highlighted in the paper. The properties of BIPV ...

Automatic building reconstruction from LIDAR data has become a hot topic for several years. Many methods and algorithms have been put forward to reconstruct the building models, such as of flat roof, gable roof, or other rectangular shapes. Among which, contour based method is an innovative one to simplify the focusing, detection and reconstruction of buildings. In this paper, the contour clust...

To establish of estimation for snow cornice on flat roofs, the authors conducted wind tunnel test using natural and field observation subjected to two buildings, then examined methods estimate roof shape coefficient based speed.
