Canadian survey of low slope roofs: profile of roof distresses
نویسندگان
چکیده
This paper presents an overview of observed distresses on low slope roofing systems collected for the Building Envelope Life Cycle Asset Management (BELCAM) project. The data include over 14,000 visible distresses from 600 roofs from seven different climatic regions across Canada. The distresses encountered for built up roofs, modified bituminous roofs and a limited number of single-ply roofing systems are examined relative to climatic region, roof age, condition, and material type. Cross population samples of the data set are presented. The examination of this data set provides insight into the potential distresses found on existing roofs managed by building owners in Canada. These distresses are used to determine the condition of existing roofs for the BELCAM project.

Roofs are the first candidates for rainwater harvesting in urban areas. This research integrates quantitative and qualitative data of rooftop stormwater runoff in an urban Mediterranean-weather environment. The objective of this paper is to provide criteria for the roof selection in order to maximise the availability and quality of rainwater. Four roofs have been selected and monitored over a p...
متن کاملRoof Drainage: Not my problem ... Maybe
Many strucrural engineers are surprised to learn that the In~rnotional Building Code (IBC, 2009) requires the roof structure to be engineered for standing water weight in the vicinity of the drains and scuppers regardless of roof slope. In addition, some low-slope roofs also require special attenlion for water weight and stiffness for safety against ponding failures or protection against accele...

Analysis of the Solar Potential of Roofs by Using Official Lidar Data
This paper focuses on a field test that locates roof areas with a high solar potential and predicts the solar “harvest” per m. The test analyzes 2.5D LIDAR data provided by official surveying and mapping sources. The primary LIDAR data is prepared by masking the roofs’ contours and afterwards filtering the point cloud by a threshold value. The remaining LIDAR data, which represents the building...
متن کاملAn integrated method to valuate the function of green roofs in absorbing air pollutants; Case study: Tehran
Tehran is the capital city of Iran and its inhabitants are suffering from air pollution.Green roofs can be one of the choices to deal with this problem. In this paper, ability ofgreen roofs in absorbing four air pollutants (PM10, SO2, NO2, and CO2) in Tehran wasvaluated. First, the potential of 1 m2 of a hypothetical green roof in Tehran in absorbingPM10 and SO2 during 1 year was estimated usin...
