A real-time passive cooling apparatus reduces energy utilization in buildings using a vertical closed-loop two-phase thermosyphon with its condenser located externally of the building. The wind shear layer and the temperature of the air surrounding the condenser provide renewal cooling in real-time when the thermosyphon evaporator temperature is lower than the ambient outside temperature. A pump circulates a fluid coolant through a closed-loop piping network that includes a primary annulus formed by a pipe that encloses the thermosyphon evaporator. The pump is activated when a building cooling device temperature is above a temperature set point. There is an option to store sensible and latent energy in a secondary annulus formed by a larger pipe that surrounds the first annulus to reduce the intermittency of the real-time passive cooling apparatus. The thermosyphon can be integrated into the building to support building loads, and devices like lights, wind turbines, and solar panels |
