The embodiments foster good quality of life, prevent premature death, and costly illnesses by using its benchmarking capabilities to allow identification of inefficient energy use in multi buildings mainly for HVAC and other major equipment, which allows multi buildings to maintain a dryer and properly ventilated environment. The dryer and properly ventilated environment lowers the risk of illnesses and mold growth and reduces buildup of air pollutants. Hence improving occupant comfort, productivity, enhancing general health, which avoids costly illness and premature dead.
According to the EPA Americans, on average, spend approximately 90 percent of their time indoors, where the concentrations of some pollutants are often 2 to 5 times higher than typical outdoor concentrations. Moreover, noting that indoor Ambient (outdoor air pollution) is a major cause of death and disease globally, the health effects range from increased hospital admissions and emergency room visits, to increased risk of premature death. The World Health Organization estimates that 4.6 million people die each year from causes directly attributable to air pollution. Many of these mortalities are attributable to indoor air pollution. Worldwide more deaths per year are linked to air pollution than to automobile accidents.
The embodiments prevent environmental harm by creating and sending automated alert reports to clients when alert thresholds have been met, therefore, reducing the wasted energy consumption by fostering energy usage savings, using substantially less energy and reducing the amount of carbon dioxide produced to the environment. Issues may include but not limited to client's issues with HVAC systems scheduling process, or human error, a facility manager forgetting to change setting on HVAC units, and leaving the units on for one for months a time. According to the U.S. Department of Energy in the United States alone, buildings account for almost 40 percent of national CO2 emissions and out-consume both the industrial and transportation sectors.
The embodiments reduce owner costs of energy consumption by providing alert reports that are to see and alerts that immediately pushed to a cell phone or their client device.
The embodiments reduce owner cost of energy consumption by providing daily report with analysis that can be compared to base year kWh usage to determine optimal timing for equipment rehab or replacement.
