As a firm headquartered in the Kansas City area with offices across the US, including the northeast, big temperature swings are something we’re used to here. This week, as we face an arctic blast brought on by the polar vortex, many of our clients are facing the prospect of single digit (and below) temperatures. This is what we call a “design day,” which presents the maximum conditions that an HVAC system is typically designed to handle while maintaining the desired space temperature. The high in the Kansas City area on Friday is predicted to be around 5°F, which corresponds with the 99.6% heating design temperature guidance from ASHRAE.
In preparation for these frigid temperatures, there are a few things building owners and operators can do to help maintain control of their systems and keep their buildings warm during these cold snaps.
In some high-rise buildings, street-level tenants may find it nearly impossible to keep their space warm despite following these recommendations. In these cases the difficulty may be a result of stack effect, which causes cold air to be pulled into a space because of a pressure imbalance due to improperly isolating the tenant space from the main building.
