Over the last couple months, this column has been about retrocommissioning, commissioning existing building systems that have never been commis-sioned before. There is no question that there is great potential to be realized through a retrocommissioning process, primarily in terms of improved system performance and decreased energy consumption. However, successful retrocommissioning is not something can be accomplished in a vacuum by a commissioning professional; it depends heavily on the building’s O&M staff.
Last month, this column addressed special considerations

customized tenant fit-out (TFO) of occupied spaces as they are leased.
Documenting the owner’s project requirements/design intent is valuable for any
project and is imperative for commissioned projects.
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.
