Preliminary Performance Tests and Simulation of a V-Shape Roof Guide Vane Mounted on an Eco-Roof System

Lightning Protection of Roof-mounted Solar Cells

Working paper developed for a NASA-sponsored study of solar cells Significance Part 6: Tutorials, textbooks and reviews Lightning interception by an unprotected building 30 feet high x 45 feet long on flat land, in the Cleveland area, can be estimated at one strike per 200 years on the average. However, peculiar configuration can easily affect this estimate upward or downward. Means are availab...

atrium and daylight performance in office buildings: effect of atrium’s roof shape on daylight reception

the first step in evaluating the visual performance and energy efficiency provided by daylight, requires an accurate estimation of the amount of daylight entering a building. the atrium concept allows the exploitation of daylight by bringing natural light into the center of the buildings, thus enhancing even a more distribution of daylight. daylight reception through an atrium is particularly b...

Bayesian parameter estimation of convective heat transfer coefficients of a roof-mounted radiant barrier system

This paper deals with the application of Bayesian methods to the estimation of two convective heat transfer coefficients of a roof-mounted radiant barrier system (RBS). As part of an empirical validation of the thermal model of the roofing complex, a parametric sensitivity analysis highlighted the importance of convective coefficients in the thermal behavior of a roofing complex. A parameter es...

Environmental payback time analysis of a roof-mounted building-integrated photovoltaic (BIPV) system in Hong Kong
