Current building codes may require certain building owners to document elevator pressurization when renovating areas of a building. Depending on the measurements, building owners may be faced with the requirements of either installing fire rated doors in elevator lobbies, or upgrading/repairing the elevator pressurization systems to maintain the proper pressures in the event of a building fire. Some of our clients have been faced with a renovation requiring the entire building being brought up to current code in regard to elevator pressurization. Installation of fire rated doors may not meet tenant expectations and is a costly endeavor. PENTA is well versed in measuring elevator pressurization and assisting our clients with design and implementation of corrective measures to achieve proper pressurization.
