Despite ASHRAE continuous effort to prototype and experiment with new resources that integrate science and technology into HVAC buildings, design fundamentals still being challenged by the gap between intended design and actual building energy performance. There still today a continuous struggle to develop the ultimate HVAC-system that can effectively integrate equipment energy [Heat/Cold] production with distribution.
ZERO-MIXING AND THE SYSTEM PERFORMANCE
Zero-Mixing/SBT HVAC retrofits not only resolve the energy-efficiency / economical problem; but also, the environmental problem associated with the unnecessary burning of non-renewable and the increasing production of buildings GHG emissions. In the case of condensing boilers..........
System Water-Mixing; resulting from hydronics evil, and the lack of system Thermal-Mass are the worst enemies of system performance.
