New Profiles Of Occupancy Driven Loads For Residential Sector Energy Demand Modelling

Dane George, Lukas Swan

Abstract: Energy modelling is used by researchers to estimate aggregate energy consumption and time-step demand (power) of buildings. When considering new building technologies, time-step demand modelling plays an important role on several levels: 1) it allows homeowners and builders to determine viability within time-of-day energy and demand pricing schemes and smart-metering response; 2) it can help utilities accurately forecast short term loads so that they can procure sufficient capacity, especially with consideration of residences opting for new technologies that affect load profile; 3) it can inform the creation of energy policy to support implementation of technologies that may have a desirable effect on community load profiles. Building simulation tools can address these issues by providing accurate energy consumption estimates for homes and communities. However, researchers often rely on a limited number of synthetically developed electricity and domestic hot water (DHW) load profiles and these do not permit comprehensive demand evaluation at a community scale. Recently, occupant load data has become available through electrical utility ‘smart metering’ programs, academic and industrial research endeavors, and municipal energy savings programs. Four separate datasets have been obtained for our research project: • two datasets including 1-minute time-step DHW consumption measurements from 41 and 119 houses • one dataset including 15-minute time-step wholehouse electricity load measurements from 161 homes • one dataset including 1-minute time-step disaggregated electricity load measurements from 23 homes From these datasets, annual time-step DHW and electricity load profiles have been generated. To demonstrate the effect of using a variation of profiles, a community scale energy model is being created, utilizing a set of single-family detached house Archetype building models developed by the U.S. Department of Energy. This paper presents these new profiles and the initial stages of work completed to demonstrate the effect of using a variation of profiles on a community scale.
