Intelligent Control
The Efficient Energy America (E2A) centralized supervisory control and data acquisition system for commercial applications is an easily installed, highly intelligent automated building energy control solution. The system allows control of HVAC loads, lighting and energy data collection and monitoring for any location from local to enterprise level.

The system implements unique concepts and control algorithms that allow users to optimize HVAC performance, reduce power consumption and lower energy costs as well as cost of equipment ownership.

The Problem
Typically, energy used for space heating and cooling through HVAC systems makes up a large proportion of the energy used by commercial buildings. In many commercial applications, the HVAC energy load has proven to be in excess of 50% of the total energy consumed. As a result of a number of factors, such as poor initial design, lack of maintenance, poor control strategies and equipment age, HVAC units generally over consume and underperform. Heating and cooling controls typically operate by achieving fixed pre-programmed temperature targets or are switched by simple On/Off operator or timer functions. Even in the best maintained systems, building owners and managers tend to compensate for HVAC systems by making heating and cooling times longer than necessary to ensure temperature is reached on time. Aside from internal space temperature, other environmental influences are not normally taken into consideration within the controls. This leads to unnecessary over-usage of equipment, resulting in "wasted" energy.

The Efficient Energy America Solution
The E2A system provides sophisticated control functionality to commercial buildings that may normally lie outside the range of standard BMS/BAS systems. Easily installed, without impact to the existing building structure or electrical wiring, the system brings a functionality that will reduce utility bills by eliminating non-essential run-times, controlling HVAC units based on more accurate building and environmental data than can be attained from standard thermostats, and managing demand so that there are no unnecessary demand increases based on coincidental start-times or outside influences.

The E2A system offers automated centralized supervisory control through of a number of wirelessly distributed control interfaces, sensors and a master controller.

The E2A system allows for the reduction of power consumption (kWh) through a number of unique control methods.

Methods used include:

• Centralized Supervisory Control
• Smart Scheduling
• Set-point Optimization
• Performance Optimization
• Predictive Preventative Maintenance
