The application of computerised optimisation techniques to the design of low and netzero energy buildings would provide building designers with a powerful design tool. This paper presents such a tool that is being developed that links TRNSYS energy simulation with an optimisation program based on genetic algorithms. This early design stage optimisation tool(More)
Homes that utilise solar thermal and solar photovoltaic (PV) technologies to generate as much energy as their yearly load are referred to as net-Zero Energy Solar Homes (ZESH). One of the most important tools in designing a ZESH is the building energy simulation software that is used to evaluate different design configurations. The modelling of ZESH is more(More)
This paper investigates the use of simplified linear transfer function models −obtained from system identification of results obtained with building simulation tools− for the development of control strategies in solar homes having passive and active thermal storage capabilities. Solar homes are defined here as those using solar radiation to meet a(More)
This paper develops convective heat transfer coefficients for several different BIPV/T system configurations using Computational Fluid Dynamics models. The results for one of the CFD cases are validated with experimental data from a BIPV/T installation. The second part of the paper describes a model which is used to generate annual performance data for the(More)
The need to control solar gains is often in conflict with the need to satisfy daylighting requirements. Utilization of daylight could reduce electricity consumption for lighting and increase occupants’ productivity. On the other hand, admission of excessive solar gains could result in increased cooling energy demand. Therefore shading provision should be(More)
Semi-transparent photovoltaics (STPV) have a large potential for integration in fenestration systems, adding the option of solar electricity production while still allowing for satisfaction of daylight needs. This paper studies the potential of using such a technology and examines the impact of changing the photovoltaics (PV) area ratio (ratio of PV(More)
This paper investigates the use of a multi-level simplified linear thermal modelling approach based on the electrical analogy for the development of control strategies in conventional detached residential homes equipped with convective electric heating systems. These models are developed from parameter identification of results obtained through comparison(More)
This paper presents a fundamental parametric study on the effect of a number of room design parameters for radiant and convective heating sources as well as solar gains. This study is performed using frequency domain modeling approach by means of which important room transfer functions are obtained and studied. A room is considered with different types of(More)
