Michelson Laboratory China Lake, building 5, is a 543,000 square foot historical building with over 1,600 employees. The facility is broken up into multiple wings which
houses complex computer servers, large UPS systems, research and development, manufacturing, and administrative areas. The facility has its own central cooling plant which has close to 2000 tons of cooling and is feed steam from a central heating plant.
Other important factors related to the facility are the multiple clean rooms, high altitude chambers, heat treatment, and materials plating.
The facility is heated and cooled through use of hot deck / cold deck, constant volume AHUs. Much of the facilities energy and water use is not only related to cooling and heating, but for process equipment.
Statement of Work:
SEA performed energy and water assessments of the facility including: building energy efficiency simulations, cost evaluations, life cycle saving analysis, investigation of HVAC systems and controls, uninterrupted power supply systems, lighting systems, envelope, process load, plug load, water heating, water conservation, thermal storage systems, and renewable energy including wind and photovoltaic.
Our recommendations of more than $20,000,000 included the following.
- Water Conservation
- Upgrade Fluorescent Lighting
- Lighting Controls
- Destratification Fans
- Constant Volume AHU’s to VAV
- Variable Speed Pumping
- Premium Efficiency Motors
- Frequency Converters
- Fume Hood Improvements
- DDC Improvements
- Window Upgrades – Acceptable with Historical Standards
- Daylight Harvesting
The savings analysis revealed close to $1.2 million dollars per year of avoided cost. The savings in energy and water will be obtained by not using nearly 2,500 kilogallons of water, nearly 5,000 MWh of electricity, and greater than 10,000 MBTU in gas.
