Abstract
The Tennessee Department of Environment and Conservation (TDEC) completed a pilot project within its Central Office spaces to test the utilization of computer power management (CPM) technologies to implement power saving settings on state-owned, network-connected computer equipment. Currently, the State of Tennessee has no clear protocol regarding energy-conserving power settings on state-owned machines. Activation of monitor sleep modes and system standby and hibernation modes on 615 Central Office computers over an 18-month period reduced energy consumption by an estimated 8093 kWh and $526 per month, amounting to approximately $6312 in cost savings for Tennessee annually. If implemented throughout State of Tennessee executive agencies across the state, energy cost savings could amount to an estimated $323,341 annually. The research endeavored to understand both positive and negative impacts that strategic power management approaches can have on energy consumption, worker productivity, network security, and state budgets. Nearly all impacts discussed were positive. Based on successful results within TDEC Central Office spaces in Tennessee Tower, and considering the potential cost savings that could be achieved, expansion of the implementation of computer power management policies to machines in offices across the state was recommended.
Highlights
As our technology within society has become increasingly advanced and commonplace, work environments have seen an increase in computing equipment, which requires generation and consumption of electricity for operation
Previous research notes the opportunity for computer power management to provide savings based on modeling projections; few studies document actual energy and cost savings achieved through computer power management programs, within a larger sample size and within public sector workplaces over an extended period of time
The Tennessee Department of Environment and Conservation (TDEC), in collaboration with the Department of Finance and Administration’s Office for Information Resources (OIR), completed a pilot project within its Central Office spaces to test the utilization of computer power management (CPM) technologies to implement power saving settings on state-owned, network-connected computer equipment
Summary
As our technology within society has become increasingly advanced and commonplace, work environments have seen an increase in computing equipment, which requires generation and consumption of electricity for operation. The Tennessee Department of Environment and Conservation (TDEC), in collaboration with the Department of Finance and Administration’s Office for Information Resources (OIR), completed a pilot project within its Central Office spaces to test the utilization of computer power management (CPM) technologies to implement power saving settings on state-owned, network-connected computer equipment. The intent of this effort is to better understand both the positive and negative impacts that strategic power management approaches can have on energy consumption, worker productivity, network security, and state budgets.
