As a contractor I'm well aware of these increased green costs, for a quality home here it's costing $1,000 a square foot and up, even the cheap affordable housing stuff is over $500 a foot in costs. There are so many toxics in building materials today that 62.2 IAQ is tripling, this is going to be counterproductive as we are sealing up and then pumping in air, my carpenters built two spec homes in the industrial city of South San Francisco, after the architect went through 7 years of permitting they built the 2,500 square foot homes and sold them for $1.25 million, that's $500 a foot, they lost money, they tried to include their land costs in construction costs and they didn't charge for their labor, so they worked for free and lost money at $500 a foot, these are efficient good carpenters who are Mexican American. In the end they had to get blower door tests to prove 62.2 compliance before the tripling, the blower door guy had them cut 2'x2' holes in the laundry rooms to pass, then they sealed them back up. Now blower door tests are going to be required before completion to make sure they are sealed up. This is crazy.
I'm well aware of the window requirements, for 14 years I've been installing U-0.18 triple pane windows, that's about R-5.6, the DOE wants the R-5 window now so all windows are going to have to be triple pane, the DOE is going for the R-10 window and nobody knows how they are going to achieve that (Cardinal has a coating that they claim
will deliver R-5 in a dual pane, but that's a COG rating and the DOE wants full frame NFRC ratings, not even close). My Title 24 consultant has long told me that anything below R-5 (U-0.20) is a waste of money, replacement windows have always been a fraud, in most cases they do more harm than good. BTW, Cardinal will no longer deliver to me in California because of our tax and liability decisions, they will deliver to their fabricators, I have ongoing seal failures and since I warrant my products for life I'm having problems replacing failed units. An attorney friend told me he had a 20 year home and was paying about $3,000 to $4,000 a year in IG unit replacements, he asked if he was saving any money over just single pane windows when you factor in IG unit replacement? I told him of course not, you are not saving money you are saving the planet, it is costing a lot of money to save the planet. Why do we keep doing this, the planet has been cooling for 16 years, the fraud is over.
The cool roof thing can be confusing, Steven Chu (Obama's former Secretary of Energy and Nobel laureate in physics) has long campaigned for every roof in America to be painted white to reflect sunlight back into space to save the planet, the problem with that is in colder climates (like the city of San Francisco) you want dark roofs to absorb the heat, not reflect it. Cool roofs now code-wise have come to mean radiant barriers on the bottom of roof sheathing to reflect heat back into the home. This too is crazy, differing climates require differing approaches. This reminds me of the time the State License Board sent me to a home in San Francisco, the lady had changed her windows from the original good quality aluminum casements (that sealed well) to cheap dual pane vinyl, she was sitting in her living room covered with a blanket shivering, I asked her why she did this, she said: "I just wanted to be toasty warm." My heart went out to her so I called a guy who had just written the AAMA Manual and told him the wind was blowing right through these cheap windows, his response was: "Of course she is colder she lives in San Francisco, that is a cold city and she's blocked out her solar heat gain." I asked: "Shouldn't people in San Francisco be told that?" He said: "Of course not, we can't go dividing this state into micro-climates, on average if everyone in the state installs dual pane windows we will save 2% in our average energy consumption." So people in cold and hot climates suffer, but on average the statewide energy consumption lowers by 2%, welcome to communitarian socialism, or fascism.
