ENGLEWOOD CLIFFS, N.J. — LG Electronics USA announced that its Multi-V IV variable refrigerant flow (VRF) air-source systems have been certified to exceed California’s stringent seismic building requirements. The company said these air conditioning systems are now certified in all 50 states.
With a seismic testing design acceleration parameter of SDS (g) = 2.95, these products exceed the maximum USGS defined SDS (g) = 2.50 for the contiguous United States, Alaska, and Hawaii and secured seismic certification in accordance with a number of compliance codes, including: International Building Code (IBC) 2012, California Building Code (CBC) 2013, American Society of Civil Engineers (ASCE), Minimum Design Loads for Buildings and Other Structures ASCE 7-10, and California’s Office of Statewide Health Planning and Development (OSHPD) Preapproval Procedure with shake table testing in accordance with the International Code Council’s ICC-ES AC 156 2012.
With increased understanding of the dangers of seismic activity in the United States, compliance certification is more important than ever before for certain building projects, said LG.
States located near fault lines including California, Utah, and Kansas are taking the lead in codes and standards and requiring both new construction and retrofit buildings to be built to continue operation in a seismic emergency for safety reasons.
To ensure building safety and widen the range of installation projects, LG pursued certification for key products from the company’s Multi-V IV VRF commercial air source product line.
By earning the OSHPD Special Seismic Certification, LG’s Multi-V IV products now can be utilized in new construction or renovated construction of hospital building projects in California, one of the most seismically threatened states in the contiguous U.S.
IBC certification means that LG’s Multi-V IV products can be utilized in new construction or renovated construction of occupancy category IV building types having an Importance Factor 1.5 or greater, including hospitals; fire, rescue, and police stations; emergency shelters; and power-generating stations. Typically, during seismic emergencies, buildings of this category must continue to operate and serve the public, and they need HVAC systems that can perform during emergencies.
These seismic compliance certifications allow LG to further expand its new construction and retrofit installations, providing comfort for a greater range of projects not just in California but also throughout the United States.
