AES™ Case Study 8383 Wilshire Blvd, Beverly Hills ENERGY STAR Score 100% Building Size 417,463 sq/ft Year Constructed 1971 This building was upgraded with AES™, a carbon monoxide monitoring system and the installation of Variable Frequency Drives (VFD) on all major equipment, including one of the two 700-ton centrifugal chillers.
next>edge uses AES™ software to monitor and control all fan operation, chiller loading, load shedding, start/stop timing, and condenser water temperature set-points. This system monitors, resets and adjusts the highly efficient variable-flow pumps, high efficiency motors and all direct digital controls. The supply air duct static pressure set-points were programmed on a floor-by-floor basis with specific instructions in how and when to reset, fully integrating the entire system to yield high-efficiency results. The carbon monoxide monitoring system provides the fan systems with better control, allowing the systems to provide better ventilation to the parking garage, while reducing excess energy consumption. The horsepower reduction and associated energy savings have been very significant.
Reduced Energy Usage 1,989,800 kW/year (28% energy savings) Equaling $188,980/year in Utility Costs

AES™ was used to fully integrate the existing Energy Management System (EMS) and further reduce energy consumption through the following measures:

	A Demand-side management program was developed using AES™ to control and monitor peak kilowatt demand and provide monthly analysis of peak demand
	The reduction of simultaneous heating and cooling to a minimum by spreading the load over time, using AES™ to create an optimal start strategy, allowing maximum use out of the EMS

AES™ also automated the following low cost/no cost best practices into its sequencing:

	Automate the use of outside air to pre-cool the building
	Pre-cooling and pre-heating of the building at night during low energy use/cost times

AES™ programming and commissioning takes into account the financial impact of electrical demand charges and targets its operation goals towards peak demand reduction to avoid the high cost of peak hour electricity. By monitoring electrical demand levels and establishing a peak target, AES™ is programmed to selectively reset equipment to keep the demand within defined limits while never compromising occupant comfort.
