Ramland Holdings LLC purchased a vacant flex office/warehouse building in Orangeburg, NY. The building was one story high with a partial second story. Ramland intended to develop it as a data center. That type of use would require installing a substantial amount of rooftop and outdoor ground level equipment to maintain interior temperatures, as well as back-up power, for data center tenants. With a residential neighborhood barely 500 feet from the building, cumulative noise levels were a source of concern. Ramland asked SEA for assistance in evaluating potential noise impacts and mitigation measures. SEA reviewed alternative site plans and equipment specifications from multiple vendors and carried out modeling with Datakustic’s CadnaA noise model.
