The application of energy recovery units allows for the ability to do total heat recovery and recover both sensible and latent heat from an exhaust air stream, using that heat to pre-condition outdoor air required for building ventilation.
Both new and existing building projects should have lighting control provided, either as part of a standalone system or, ideally, integrated as part of the BAS. But we often find that there are many reasons automated lighting control is not provided, ranging from simple economics to frustration with the programming and support of these systems.
Many engineers tend to avoid or delegate the nitty gritty of a ground source heat pump system, from soil moisture effects to building system (im) balance. It's time for designers to get in the loop.
