Grey Water Diverters - The Beginning of the Transition to the Sustainable Homes of the Future?

A Presentation by Tony Green

tony green pic 2Gartner estimates a typical family home could contain more than 500 smart devices by the year 2022. These devices, which will be a major part of the Smart Homes of the future, could revolutionize the way we live in our homes. The recent drought has caused homeowners to re-evaluate the most efficient method of managing water use in their homes. The remote capability to operate a Grey Water Diverter Valve poses a glimpse into the possibility of the impact Smart Homes will have in the future as well as sustainable living practices. I will cover questions such as: 


  • What are Smart Homes and Smart Devices?
  • What type of applications of Smart Devices are used in the Smart Home?
  • What are the key requirements of Smart Devices for use in the Smart Home?
  • What is the status of the implementation of Smart Devices?
  • How can water consumption be managed in the Smart Homes of the future?

Come join us for this special EcoGreen Group meeting.

Smart Home, Preliminary Results


green house pic 2The smart home is defined as a 'building' where various devices, equipment, and products can be monitored and controlled through the application of smart mobile devices. This includes the control of lighting, heating, cooling, consumer electronics, safety and security, smoke and hazardous gases.

In  this talk we study the thermal behavior of smart home under various conditions, such as with and without attic. Our experimental work was performed during summer and temperature variations were measured. In order to increase the performance of the attic we used axial fans to reduce the temperature of the attic. Then we used high reflectivity material to decrease even more the attic temperature. In the final part, we removed the attic and repeated the same procedure. Our results showed the importance of attic on thermal behavior of smart home. 

  • Thermal behavior of smart home studied under various conditions
  • Performance measured during summer with axial fans
  • High reflectivity material used to decrease attic temperature further
  • Removed attic to show its importance on thermal behavior of smart home
