HEM1

 

Home Energy Management (HEM) refers to technology that helps homeowners improve home energy efficiency while also giving them access to household products from tablets, smartphones and computers. HEM systems save people on energy consumption (thus money) and time. With the remote controlled access, one can control thermostats, lights, smart outlets and plug strips, other appliances or home monitors via the internet.

HEM systems include smart thermostats, smart appliances that regulate energy consumption, smart outlets and smart plug strips that turn completely off when not in use. An increasingly common addition to HEM systems are home monitors, including ones that provide home security systems. However, the product that best exemplifies HEM is the programmable thermostat.

Of the smart thermostats, The Nest (the pioneer of this technology, introduced to the mass market in 2011), continues to be the most popular brand. The Nest makes it simple to change the temperature of your home from your computer, mobile device or tablet. Another popular and innovative smart product, the Ecobee3, is an example of a smart thermostat that offers an additional unique feature. With the Ecobee3, thermostats can be programmed to control the temperature in up to 32 rooms (with additional sensors). If the temperature in a multistory home varies from room to room due to a standard HVAC, the Ecobee3 offers a solution. These are two examples of user-friendly smart thermostats.

Another HEM product is the smart outlet. With the smart outlet, the power of any home appliance can be measured. Through a tablet, smartphone, or PC, the outlets can also be used to set schedules for lights or electronics. The schedules can be coordinated with the grid to have a reduction in energy consumption during peak energy production hours, if the utility offers such data. Smart appliances (like a smart washer/ dryer) can reduce their energy consumption during peak hours as well. In addition, the latest in HEM offerings is a complete home monitoring system with smart outlets, combined home alarm and security system and a a remote controlled thermostat.

 

Today, service providers other than utilities are at the forefront in the smart grid, in part due to HEM products. Companies that provide cable, internet and smart phone services are now adding energy monitoring, control and optimization services to their offerings, pushing utilities into a supporting role. Utilities and service providers are both experimenting with different approaches. The service provider is a promising alternative to utilities to extend the smart grid into more homes.

Green Urban Planning

Today, green urban planning is more important than ever. We provide facts about seven cities that are focused on utilizing various approaches to sustainable development. You can find out about many sources of renewable energy here.

City planning committees around the globe are becoming more focused on the importance of using sources of renewable energy, rather than fossil fuels and other finite resources. Our goal is to teach our readers about eight of the greenest cities in the world. As you peruse this site, you will gain insight into the worlds of renewable energy, urban planning, green building and sustainable mass transit. For instance, you will learn about an example of a bus system, located in Curitiba, Brazil, that serves as a standard of efficiency for other metropolises throughout the world...

 

Sustainability Trends

Ideas for a Greener Home

  • Reduce, reuse, recycle
  • Use eco-friendly cleaning supplies
  • Favor cloth over paper products
  • Chlorine-free baby diapers/ wipes
  • Choose natural lawn care - stop using pesticides and synthetic fertilizers
  • Use biodegradable detergent and oxygen bleach
  • For clean, safe drinking water without all of the waste - use a water filter and a reusable bottle
  • Install low-flow toilets

Energy Saving Ideas

  • Use CFL or LED light bulbs
  • Use Energy Star labeled equipment
  • Turn off all home and office equipment when not in use
  • Turn off lights when not in use
  • Turn down the thermostat - lowering it by just one degree can reduce heating energy costs significantly
  • Avoid phantom loads (electrical equipment that still uses energy even after turned off) by using a power strip
  • Reduce your water heater temperature from 140 degrees to 120 degrees
  • Install double pane windows
