TCAAP Energy Integration Resiliency Framework <br />Policy White Paper – Energy Efficiency Strategies (Demand-Side Management) <br /> <br /> 38 <br />Monitoring-based commissioning is the process of continuously monitoring building energy <br />consumption to identify new inefficiencies so they can be addr essed immediately. While ongoing <br />commissioning activities have upfront costs, monitoring-based commissioning will reap more energy <br />savings at a lower unit cost, and tie-in with advanced metering and communications infrastructure at <br />the site.14 This strategy will be most cost-effective for large commercial buildings, particularly those <br />approaching 100,000 square feet or larger. <br />Figure 4.

Direct Current Utilization <br />The fastest growing use for all energy consumed in the home is the electricity used to run appliances <br />and electronics. As of 2009, appliances, electronics, and lighting comprised 35% of all energy <br />consumed, second only to space heating.15 Of this 35%, approximately 20% of this energy is demanded <br />by electronics that run on direct current (DC) power, which is currently provided when standard outlet <br />AC current is run through a converter box.16 This is true for electronics such as computers, laptops, <br />smartphones, and flat screen TVs. The result is that 13% or more of demanded electricity in <br /> <br />14 http://esl.tamu.edu/continuous-commissioning <br />15 EIA. March 2013.
