Passive Solar Heating + Active Solar Power = A Zero Energy Home!
Here is an interesting news story on an actual ‘zero energy home’. It produces all of its own energy! The whole house runs on solar energy and uses both active solar power and passive solar heating systems. In fact, the house converts so much solar power that it sells it back to the power company for other houses to use. The story estimates this ends up saving over $2000 a year on their heating bill.
The house takes solar energy from its solar panels on the roof. However, it also uses passive solar heating systems in the form of triple-pane insulated windows. From some of the images shown it also looks like it uses insulation in the roof at the least. I would imagine it also uses a passive solar water heater to further save on power usage. The house looks very bright, so must allow plenty of sun and heat through accurate and generous window placement.
In the spirit of the ‘green living’ the house actually uses recycled soda bottles for carpet! It even looks surprisingly comfortable. The news article bills it as the first affordable zero energy home, priced at around $260,000. It is a great example of solar technology getting cheap enough to actually use. I also like how it combines active and passive solar heating systems to produce an extremely energy efficient home. It is still a bit pricey for me at the moment, but I’m happy to save money with my DIY solar water heater in the meantime!
