2005-08-16 - We are pleased to inform you of the recent release of the Passive Solar Heating Project Model (Version 3) in French and English. This updated model, which includes a new Sensitivity & Risk Analysis worksheet, can be downloaded free-of-charge at the RETScreen Website .



The RETScreen International Passive Solar Heating Project Model can be used world-wide to easily evaluate the energy production (or savings), life-cycle costs and greenhouse gas emissions reduction for passive solar designs and/or energy efficient window use in low-rise residential and small commercial building applications. The model can be used where there is a relatively significant heating load. The model calculates, for both retrofit or new construction projects, the difference in heating and cooling energy consumption between a proposed passive solar building design (or energy efficient window use) and an identical building but without the passive solar (or energy efficient window) features.
