Residences
Friedkin Residence, Napa, CA
For over 7 years, RNM Engineering has worked directly for the owner, designing the power distribution system for this 30,000SF residence/compound. The project started with PG&E removing an unsightly overhead high voltage line and installing an underground cable. Major features include- an industrial style underground ductbank system distributing power to seven buildings, an emergency generator and a load shed scheme using remote control circuit breakers with interfaces to the HVAC system and the lighting control system and a grid-tied Photovoltaic system.
Airports
Sacramento International Airport, Sacramento, CA
Working as a consultant to Enovity, Inc. of San Francisco, RNM Engineering provided enhanced LEED commissioning on the electrical distribution system and lighting control systems for the remodeled and expanded Sacramento Airport. Designed the electrical commissioning plan and prepared the detailed testing procedures for the 12,470 volts dual loop distribution system, generator paralleling switchgear, main switchboard throwover scheme, load shed sequence, and California Title 24 lighting control systems.
Hotels
Four Seasons Spa & Resort, Santa Barbara, CA
RNM Engineering was engaged by a Canadian engineering firm to be the CA-based project electrical engineer providing design and on-site electrical engineering oversight during a major remodeling of this historic, world-class hotel and resort. The hotel stayed in full operation during this project. Additional projects for the hotel included the electrical design for an off-site laundry, and the electrical design for the upgrade for a sewage lift station.
Retrofits
Building Owners and Managers Association, San Francisco, CA
PG&E hired RNM Engineering to provide electrical engineering services for a lighting efficiency demonstration project in the downtown San Francisco offices of the Building Owners and Managers Association(BOMA). The project required measuring the lighting energy consumption and illumination before and after the retrofit. RNM Engineering designed a digital addressable lighting interface (DALI) control system to measure and record occupancy, lighting usage, and available daylight in each individual room. The project culminated in a seminar presentation: “A Case Study in High Color Temperature Lighting” – highlighting the greater than 50% energy reduction achieved.
Marvell Semiconductor, Inc, Santa Clara, CA
Hired by the owner, RNM Engineering worked for over 4 years on the completely remodeled and expanded world- headquarters of Marvell Semiconductor. RNM Engineering designed and commissioned the digital lighting control system for the renovation of the five-building 746,000 SF headquarters campus for Marvell Semiconductor in Santa Clara, California consisting of 11,000 DALI ballasts, 500 control stations, 150 daylighting sensors and 400 occupancy sensors, turning the former 3Com campus into a showcase for lighting efficiency.
