Green Building Pop Quiz

Posted By on June 22, 2009

Question 1: Which of the following is the most efficient heating source:

  • - A. Electric Heat Pump
  • - B. High efficiency gas furnace
  • - C. Geothermal heat pump
  • - D. Dual Fuel heating system

 

Answer: D. Dual Fuel combines the efficiencies of an electric geothermal heat pump with a gas furnace so the system uses the most efficient heat source at a given temperature.  The system actually knows which mode to run for the most efficiency at a given exterior temperature.  Typically the colder it gets outside the more efficient it is to run a gas heat source.

 

Question 2:  How much of a tax credit can a homeowner get for installing a new geothermal unit?

 

  • - A. $2,000
  • - B. 10% of the installed price up to $4,000
  • - C. 3% of the installed purchase price with no cap
  • - D. 10% of the installed purchase price with no cap

 

Answer: D.  Geothermal systems installed after February 19, 2009 qualify for a 10% tax credit regardless of install price.  Prior to 2009 there was a $2,000 tax credit available for installing geothermal heating systems.

 

Question 3:  Why is Low V.O.C. (Volitile Organic Compound) paint an environmentally friendly choice?

 

  • - A. Because VOC’s are contribute to depleting the ozone layer
  • - B. Because VOC’s can agitate breathing conditions such as asthma
  • - C. Because VOC’s can seep into the soil and contribute to water table contamination
  • - D. All of the Above.

 

Answer: D.  I just realized all of my answers are “D”.  Maybe I’ll switch it up on you next question….or maybe not! 

 

Question 4:  What is the best score a house can obtain on a HERS rating (Home Energy Score)?

 

  • - A. HERS Score of “100″ is the best
  • - B. HERS Score of “0″ is the best
  • - C. HERS Score of “56″ is the best
  • - D. None of the above

 

Answer: B.  A HERS Score of “0″ means the home purchases no energy from the power company and it is complete self-sustaining. A HERS Score of 100 means the home was built to the 2004 Energy Code.  Interesting fact: the 2006 Energy Code is not enforced in the greater Cincinnati market and many builders’ homes would not meet this code. 

 

How do you rate? If you got…

    I’m happy to see you mention geothermal. One thing I would like to add about that is that Geotheral heat pumps are virtually maintenance free.

    I think it is fantastic how the stimulus funds are making a difference. They are being taken advantage of all the time with the installation of geothermal heat pumps to replace high energy heating and cooling systems.
