often time, when people build homes or buildings, they neglect to take the total cost of ownership into account. people look at the sticker price of the house and forget that the actual amount of money they put into their new home is dependent on renovations they need to make to expensive systems that heat and cool their home, the amount they pay to the energy company, and how often they have to replace things like their windows. passive houses take all of these things into account so that homeowners pay a little bit more up front so that they can save money for years to come. a small investment that decreases future costs and raises the value of your new home is a no-brainer.

the passive house design technique, which is very popular in germany and several other countries in europe, emphasizes some great, green technology like an energy recovery ventilator and triple-glazed windows (see more about these in the video). habitat for humanity is starting to build passive houses across the country to lessen the back-end burden for low-income families that move in so they aren’t slammed with extra costs in the end.

if we want the amount of energy we use to be smaller, we have to start by living smarter. passive house design is a great way for all of us to start making that happen.

the flow of energy in either of these situations could be controlled by creating easily installed “flapper” type diffuser located doors that open with fan generated air flow & close with no fan generated air flow. i believe simple diffuser “flappers” could potentially save folks a substantial amount of money on energy costs. i would love to see if i’m right or wrong.
