A computer model based on mass and energy balance has been developed which incorporates a range of solar flat plate air heating collector geometries and a drying model based on the thin layer drying principle. This model will be useful in understanding the extreme complexity of the drying...

Advanced computer simulation tools for analyzing daylighting features and thermal performance of buildings are improved at the Fraunhofer Institute for Solar Energy Systems. For an analysis of daylighting elements in lighting simulations, new light-deflecting structures and materials have been...

The consensus of the '92 Rio summit was that all development should aim for non-depletion of the earth's resources.The major growth region for the next decade is SE Asia and particularly the cities of South China for which Hong Kong is a role model with its dense urban construction. Recent Hong...

The five computer programs TRNSYS, PRESIM, TRNSED, ONLINE and PREBID have been put together into a program package which is the most complete solar energy system modeling and simulation software that is available today.

Computer simulation and analysis of a ground source heat pump system with horizontal ground heat exchangers operating in heating (max 5.5kW) and cooling (max 3.3kW) mode was carried out for a typical residential house, with 200m2 of living space, located in Sapporo (Japan). In spite of high...

A simulation of forced convection solar heated water system is presented. A computer program is developed consisting of independent subroutines, capable of handling the variation of the collector tube diameter, tube spacing, ambient conditions, material thermal properties, collector and system...

A dome-covered house is an example of designing sustainable buildings by learning from the optimized biological forms from the nature. The paper presents a 3-D thermal and air flow (3D-TAF) model that estimates the energy needs of a dome-covered house. The model is verified with CFD simulations...

This study analyzes classrooms, built according to a standard project of public schools in the Brazilian State of Paraná, concerning their luminic qualities. The daylighting analysis was based on computational simulations with daylighting programs, for different combinations of days, schedules...
