Various degradation patterns are established based on the roofs' characteristics, evaluating their influence on the roof claddings' service life.
The potential rainwater harvesting volume is estimated based on the total roof area, the average annual rainfall, and the runoff coefficient.
Based on the analyzed roofs, this study finds that: (1) vegetation can be more effective than insulation on reducing cooling loads due to the evapotranspiration of the vegetation-substrate system and canopy's shading effects and (2) thermal insulation shows significantly larger influence on the stand-alone retail's heating loads than the thermal properties of the substrates and LAI of vegetation.
With Ms. Brown and her husband, the visual artist Burt Barr, observing quietly from chairs, her company performed three works from the early 1970s and "Roof Piece Re-Layed," a premiere based on the 1971 work "Roof Piece," in which Ms. Brown and her dancers took to the rooftops of SoHo, cycling through gestures like envoys transmitting inscrutable messages.
In this paper, based on the relationship between roof support and surrounding rock, the authors propose a 3D dynamic optimal design method with hydraulic support and surrounding rock coupling, and subsequently the determination of the working resistance of hydraulic support at the No. 8105 coal face in Tashan mine in Datong, China, and test on site.
Ground vibration recorded at roof, pillar and floor were analysed separately and threshold value of the vibration for the safety of underground workings has been determined based on the Rock Mass Rating of the roof rock and accordingly blast designs have been optimised.
The catchment area should be calculated based on the footprint created by the roof and not by the square footage of the roof surface.
There are however, major on-going activities to research and develop roofing systems based on the foot-print of a roof tile or shingle.
