Identical schedules in the two zones simulate the heating, cooling, and ventilation of a typical mixed-use environment. One zone uses efficient fluorescent lighting and the other zone uses hybrid lighting with dimmable fluorescent auxiliary lighting. The model consists of two windowless 2500 m2 zones. Type 56 is a FORTRAN subroutine which is designed to provide detailed thermal models of buildings. The building is modeled using the TRNSYS type 56 multi-zone building model. Within TRNSYS, the light output from the hybrid lighting system model is sent to the building model.

The outputs from both models include the light produced by the hybrid lighting system as well as electricity generated by the TPV. Next it reads the available spectral component data, applies the component data to the solar spectral distribution, and calculates the amount of light and electricity that is generated by the system. The narrow-band model predicts the direct normal spectral radiation at five nanometer bandwidths.

#Trnsys modele 576 generator
The narrow-band model uses TMY2 data or the TRNSYS weather generator to obtain the magnitude of the direct normal radiation, but the direct normal spectral distribution is predicted based on the atmospheric transmission model SMARTS. The incoming direct normal radiation is weighted by the average spectral properties of the hybrid lighting components which include concentrator reflectance, secondary element transmittance and reflectance, thermal photovoltaic quantum efficiency, light fiber attenuation, and luminaire efficiency. The wide- band model uses direct normal solar radiation from either a TMY2 data file or the TRNSYS weather generator. A narrow-band and wide-band hybrid lighting model has been developed. An economic model has been incorporated into the hybrid lighting model to calculate the break-even capital cost of a hybrid lighting system based on the annual savings. The results from the simulation include the annual energy and monetary savings gained from the hybrid lighting system. The TRNSYS model is implemented using interconnected components, which include a weather generator, radiation processors, a hybrid lighting model, a building model, building schedules, utility rate schedules, and output components. The hybrid lighting system is modeled using the transient system simulation program TRNSYS. By utilizing this work, the hybrid lighting team can make design decisions based upon computer predictions of the performance of a hybrid lighting system. All of the physical parameters of a hybrid lighting system are included as variables within the software.
