Smart Home Energy Management
- 1. S MART H OME E NERGY M ANAGEMENT ................................... ..... SMART HOMES AND ENERGY .................................................... Smart Home can be defined as an ecosystem of various devices set up such that the system understands what one intends to do and helps with what one wants to do. The benefit would be better control over various areas of the house with just a voice, touch or a button. Various technologies today have contributed various components of the ecosystem like smart TVs, smart phones and other similar smart appliances along with the interconnect system for the devices. With the increase in the energy consuming devices, people started getting more and more concerned about the control over the day to day energy consumption and reducing the bills. Along with the residents, the utility companies are also finding ways to manage energy they produce and communicate with the users on effective ways of managing their energy usage. One important factor, that is also playing role here is the environment. Everybody demands latest technological comforts with eco-friendly devices. Energy Management in Smart Homes has become a necessity now. One can easily witness a number of examples where energy consumption is controlled by energy-aware individuals around. 1When Katherine Smith of Hamilton, Ontario lived in England for a year, she was impressed by a low-tech and energy free way to dry her clothes — an airer. It’s a ceiling-mounted clothes rack that has ropes and a pulley system so it can be lowered when draping damp clothes and raised to send them back up to the ceiling. She and her son also started to use electricity around the house more conservatively. “We turn out lights when we don’t need them and wash dishes by hand; we really think about what we do.” says Katherine. Katherine’s awareness about her own energy consumption made her save on her bills and contribute towards an eco-friendly future. 2 Researchers are now analyzing how energy can be saved at home by simple techniques around peak-use times. One approach is put to test by Ontario's peaksaver program. 1. http://www.nrc-cnrc.gc.ca/eng/dimensions/issue6/smart_technology.html 2. http://www.nrc-cnrc.gc.ca/eng/dimensions/issue6/smart_technology.html Beta draft -1

SMART HOME ENERGY MANAGEMENT Smart Technologies reducing home energy use 1 “The a/c might run for 15 minutes and then be turned off for 15 minutes, even though it hasn't reached the desired temperature. The temperature in the house will slowly rise, but often this isn’t a hardship and it really helps with grid stability,” says NRC's Dr. Guy Newsham. Other techniques that could be tested include: 1. Turning on the a/c earlier in the day to pre-cool the house before a heat wave hits — to see if it can be left on for a shorter period later in the day. 2. Turning off the heating element in clothes dryers for short periods, allowing clothes to dry with just the air cycle until the heater comes back on again. www.loseyourexcuse.gov 3. Using timers on devices such as dishwashers and clothes dryers, so they go on automatically during non-peak times. 4. Installing motorized blinds on windows to reduce the need for cooling. 2 But a workable solution would involve taking individual responsibility, change our own behaviors and consume less of the fuels and products that contribute to climate change. SMART TECHNOLOGIES REDUCING HOME ENERGY USE .................................................... Intervention of technology in the process could mean as simple as requiring that new computers, mobile phones, or video game consoles default to their energy- saving modes. (Some game consoles, in a default always-on mode, become energy hogs that use more electricity than the family refrigerator.) 3 Under traditional business models, it made no more economic sense for utilities to reduce the volume of product sold — kilowatt hours, or units of natural gas — than it made for makers of soft drinks or shampoo to sell less of their products. Helmut Edelmann, Ernst & Young Director, Global Power & Utilities says “Smart Technology puts unprecedented power in the hands of consumers to manage and control their energy use” If people can monitor their home energy consumption, and how the price changes throughout the day, they will change their habits to save money. 1. http://www.nrc-cnrc.gc.ca/eng/dimensions/issue6/smart_technology.html 2. http://makeanimpact.c2es.org/climate-change 3. http://e360.yale.edu/feature/why_does_energy_efficiencys_promise_remain_unfulfilled/2367/ -2 Beta draft
- 3. ..... SMART HOME ENERGY MANAGEMENT Energy companies need to reinvent An information-centric energy infrastructure on a larger scale is required to monitor and control energy usage. Adding digital processing and communications to the power grid for controlled data flow and information management gave rise to SmartGrids. SMARTGRIDS The “Smart Grid Dictionary” (Hertzog, 2011) defines Smart Grid as follows: A bi-directional electric and communication network that improves the reliability, security, and efficiency of the electric system for small- to largescale generation, transmission, distribution, and storage. It includes software and hardware applications for dynamic, integrated, and interoperable optimization of electric system operations, maintenance, and planning; distributed energy resources interconnection and integration; and feedback and controls at the consumer level. Smart Meters available around us today are one of the by-products of Smart Grids. 1Conventional SmartGrid perception reflects power sector thinking, ignores end- use servicers, and energy system features like co-generation. A system's view on SmartGrid helps better to identify end-use oriented and cost-effective options. http://www.smartgridindia.net/ Policy makers and utilities must widen options for building smart energy infrastructure (easing addiction to power grids and smart gas pipelines) suggests Morten Boje Blarke, Assist. Prof., M.Sc. Eng. PhD. Sustainable Energy Planning. ENERGY COMPANIES NEED TO REINVENT .................................................... A report by Ernst & Young (October 2011) says Energy Companies must reinvent themselves. The introduction of smart technology in energy market has brought a number of utility companies to compete and thereby forcing the energy companies to change in order to sustain the relationship with their customers. Edelmann concludes, “Smart technology puts unprecedented power in the hands of consumers to manage and control their energy use. In time, this will fundamentally shift the balance of utility customer relations. It seems the era of a one-way relationship — where a utility delivers energy to domestic consumers, end of story — is over, power and utility companies need to adapt and now”. http://smartgrid.epri.com/ 1. http://censeps.soe.ucsc.edu/sites/default/files/2011-blarke.pdf Beta draft -3
- 4. SMART HOME ENERGY MANAGEMENT eCommander - A smart energy manager At a basic level, a smarter grid means that a meter can offer consumers real-time information about electricity costs, which tend to soar at times of peak summer demand. But, says Elliott, “We’ll start seeing the real benefits when we start putting smart meters on smart homes filled with smart appliances.” R. Neal Elliott, director of research at ACEEE When will energy companies stop telling me to save energy and start helping me do it? http://www.independent.co.uk/environment/quotwhen-will-energy-companies-stop-telling-me-to-save- energy-and-start-helping-me-do-itquot-2124208.html One of the initiatives taken by SLS and Echelon for making the homes energy efficient lead to the invention of eCommander - A Smart Energy Manager SLS Energy is a division of SLS that is geared towards developing and deploying products that bridge the SmartGrid and SmartHome worldwide using Powerline and WiFi communication that interoperate with SmartPhones and Tablets. ECOMMANDER - A SMART ENERGY MANAGER .................................................... eCommander is a smart energy manager that utilizes the smart grid and smart metering technology from Echelon.
