What causes poor IAQ? What are the negative effects? And most importantly, what can be done to achieve cleaner indoor air? The following article will attempt to shed light on these questions so we can all breathe a little easier.
After an earthquake or seismic event, buildings containing essential services must be able to remain operational. Seismic certification of HVAC equipment provides assurance that the equipment will not only survive the earthquake, it will remain online and functional. Seismically certified HVAC equipment allows consulting and specifying engineers to meet the strictest seismic building codes, quickly and easily, without the delays of additional certification testing. Seismically certified HVAC equipment allows building owners to protect their investment.
