Abstract
The specific objective of this study was to investigate regional spatiotemporal distributions and spatial correlations of energy and water consumption in open, semi-closed, and completely closed greenhouse systems in British Columbia. The findings showed that the energy and water consumptions were both spatially and system dependent. Latitude and longitude significantly predicted total energy and water consumptions. Semi-closed and open heat pump systems were the most energy conserving systems while closed system was the most water conserving. Semi-closed and closed systems at lower latitudes had more water consumptions compared to those at higher latitudes while open systems at higher latitudes had more compared to those at lower latitudes. Locations close to the southwest Pacific Coast had the lowest energy and water consumptions in all systems.
