New Solar Power Incentives - Federal & State

So it seems Good Things really do come to those who wait! (or is it "Time and tide wait for no man"...?)

Solar PowerHad a great call with our Solar Contractor who re-quoted our Solar PV system based on the new Federal and State incentives available for Solar Photovoltaic electric panels.

Turns out, there are a number of changes to the incentives that really make a difference in moving forward. Of course, there is still some silliness (like not being able to take a Solar PV and Solar Hot Water incentive in the same year - ugh). Nevertheless, we are excited to see the government put (our!) money in the right places.

Summary:

  • Federal =Government Offers an uncapped 30% Tax Credit for cost of system

  • NYC = Property Tax Abatement - 35% of Post Rebate Cost - Over 4 Years

  • NYS = Offers 25% Credit of the Customer Final Payment up to $5,000

  • Utility Rebate = NYSERDA Rebate for Solar Electric System (Currently $3.00 per watt)

In our case, that leaves the Net cost to us, after 4 years at under $5,000. w00t!

It's time to go and get your Solar On!

Note that the Solar Thermal / Hot Water incentives haven't changed. Yet.

Brownstone Heated Front Steps

Woke up this morning thinking about snow, the brownstone and having to shovel the steps. Getting the ice and snow off of those steps can be Brownstone Stairs Snow a real pain, and typically you will leave snow and ice all over them, making for a treacherous run to Whole Foods for your favorite organic, free-range, hot cocoa potion and a bucket of Tiger Balm for your back.

Having spent some time in the north of Sweden, where the snow is towering over your head, I remembered that they had heated walkways nearly everywhere. The snow fell (and fell and fell...) and quickly melted.

Aha! We're installing radiant heat, powered by a Solar Thermal Hot Water system. Why couldn't we extend some of that to the front steps? To be even more efficient, there could be a switch that would allow the front steps system to activate. Wouldn't exactly be fast, but might be smart. Have to think through when I would want it on/off more. Anyone have ideas?

In review, a radiant hot water heating system distributes warm (~ 130 degrees) water through flexible PEX tubing typically installed under the floors. The amount of water carried in the tubes acts as one large heat mass; efficiently warming the house and retaining it's heat for long periods of time.

Less water heating = less fuel used = less costs = green building!

I can see a system that has a heat exchanger carrying an antifreeze liquid through PEX tubing mounted in these aluminum plates to direct the heat to the bottom of the stone steps. Remember, it doesn't have to heat the steps to 72 degrees, just 33 degrees. Also, the heat exchanger is necessary because you can't have water running to the outside pipes, unless you want to have a sprinkler system under your steps after the first freeze...

We hope to have the bulk of our hot water generated by our solar thermal evacuated tube system, but might not even need to use it for the steps if we can just have the heat exchanger interface with the incoming city water (which is between 50-60 degrees).

I'll have to talk to Contractor Sam and Ellen & Jen the architects about it. They just LOVE to hear my latest... um... innovations... alway bringing up that "what's your BUDGET" thing. ;-)

Update: Green Lighting LED and CFL Bulbs

Quick update for folks in NYC on where to find good quality CFL and LED lighting products for your home in a retail store. Great staff who are hugely helpful.

Gracious Home, now open in Chelsea, has a great new selection of Green Lighting bulbs (or "lamps" as I am told they are technically called). What I liked was that the LAMPS were organized by the color temperature of the light. How tired are you of getting a CFL or LED bulb home only to find that it's a weak white/blue when you wanted warm, soft white?

Remember for warm tones in the living room and bedroom, you want 2700K temperature lights. Don't be snookered by the "pure daylight" marketing materials; those bulbs put off a super-white-to-bluish light and are rated at 5000K. Ick. Here is the original post: Where to find quality LED and CFL Bulbs?

I was especially impressed that they were carrying the new LED under-cabinet lights from WAC. The WAC InvisiLED Tape Lights are far and away the best performing LED under-cabinet lights I've seen (and I've tried too many...). No heat. Very low energy use. Simple install. Easy to link together. Check 'em out!

Update: Green Paint Stripping

Our great progress in stripping the paint from the spectacular window trim and base molding Winter renovation
has.
slowed.
down.
considerably.

Turns out, the recent cold snap (I love saying that, like we live on the prairie, maybe near the Big Woods!) has had an effect on the efficacy of the Smart Strip product.

As the instructions clearly state:
Limitations: For best results, surface temperatures
should be 60ºF – 95ºF. Smart Strip can be
applied as low as 37ºF, however, efficiency/effectiveness
are reduced and dwell time increases.


We have the heat turned off in the brownstone, and it's been hovering around 45-50 degrees. As a result, the Smart Strip isn't turning the 100 years of paint and shellac into the easy-to-remove goop we've grown to enjoy. We may need to wait for the weather to warm up a bit. Or buy a heater for the rooms we're working in. Argh.

For the fans, here are some action shots from this weekend. Note the wool cap. It's cold!

Green Paint Stripping with Smart Strip

Happy New Year! After a few unexpected travails, we're back in full swing on the project.

Our townhouse has beautiful original woodwork, much of which had been


painted over many, many times in the last 100 years. Most of the windows and doors had been painted, and we wanted to get an idea of the work involved and how feasible it was to strip them back to their original condition. BUT, no nasty cancer-causing chemicals for us, so we tried out 2 of the green paint removal products we found:
  • Soygel: highly-rated, made from soybeans by Franmar Chemicals

  • Smart Strip: brand new product from the Peel-Away folks

SoyGel by FranmarSmart Strip

We put them both to the test. Read More...

Window MoldingHands down, Smart Strip worked better for us on the multiple layers of paint on top of the original shellac. Also, Smart Strip had *no odor* at all, had a thicker consistency and was much easier to clean up. Used in tandem with the special Peel-Away paper, we made short work of the windows and doors ikn the master bedroom. To the right is a shot of the windows before stripping, and below the detail that we found after using Smart Strip:
Door molding stripped door molding


Our Method (YMMV...)

  1. Set up your work area by taping down rosin paper, and taping off areas you don't want to be stripped.Peel-Away
  2. Apply the Smart Strip with a brush. It's a thick, white paste that sticks to the surface pretty well. We slathered it on as thick as possible (~1/4").
  3. Next, we cut the strips of Peel-Away paper and applied to the doors and windows, completely covering the paste and overlapping it a bit. The paper slows down the drying process, allowing the product to work on the layers of paint.
  4. First, we waited 24 hours, but found that 48 hours was the right amount to get through all the layers.
  5. This is a good time to go and find Allway CS6 Contour Scraper Kit, a flat scraper, contractor bags, a nylon stripping brush, denatured alcohol, latex gloves and a ton of rags to clean the scrapers off. TIP: we used saved plastic grocery bags to wipe the scrapers off in. No mess!
  6. Gently pull off the Peel-Away paper, s-l-o-w-l-y, working perpendicular to detail in the molding. Smart Strip You should be getting several paint layers stuck to the paper, and sometimes all of the layers, with the shellac or varnish in a gel.
  7. Grab your scaper(s) and gently glide it across the now bubbled and soft paint layers on the wood. The paint should slide off easily. If it doesn't, work on the areas that do slide off, and plan on applying another treatment of Smart Strip.
  8. Wipe the scrapers off on the rags, or in the plastic grocery bags. Resist the temptation to wipe it on the rosin paper, as you will then be stepping in the goop, and tracking it around. Yes, that is from experience...
  9. Once all the loose paint is removed, pour the denatured alcohol into a spray bottle Stripping Molding and spray it liberally on the woodwork, scrub it vigorously with the nylon brush, and then wiping it off with clean rags. Move quickly over small areas, as the alcohol dries fast. TIP: if it's shellac underneath, Denatured Alcohol works. If it's varnish, use Mineral Spirits.

Hopefully, all of the shellac and varnish comes off easily with the rags and Denatured Alcohol/Mineral Spirits. If not, STOP, and just re-apply Smart Strip for 6-12 hours, and it will loosen the shellac. You will not get it off easily otherwise.

  • Do not scrape at hard paint - the woodwork will be destroyed, and you will be frustrated.
  • Do not let the Smart Strip dry with the Peel-Away paper on it. It's a hassle to get it off when dry.
  • Do not coat on more than you can remove in one stretch. What you put on, make sure you get it off before it dries.

Voila! You should have some darn fine woodwork in front of you. (Of course, the usual sanding, etc.will have to happen before applying a new stain or shellac.)
