The Lawrence Street House – Bidding and LEED

I know it’s been a little while since I gave you all an update on the Lawrence House. With the holidays, I took a bit longer finishing the drawings and we really didn’t want to have to be doing open houses during the Thanksgiving and Christmas season. Open Houses are actually kind of a pain. Clean the house, keep it spotless, etc. for a two to three hour window on a Sunday afternoon. So we rested that for a while.

BIDDING
I also got the drawings done and ready to go out to bid. Based on my original budget, we had our present house priced at where we needed to be for a little negotiation and be able to go straight across. Part of the triple bottom line (the three “E’s” of sustainability) is economy and we didn’t want to end up with a mortgage when it’s all said and done.

But I’ve been getting preliminary bids back and they are actually coming in under my original budget (which, frankly, was pretty generous). So now we’re starting to get pretty excited. This may actually happen! We’re also currently at 5kw for the solar and are considering 6kw. We have room on the roof and believe it’s the right thing to do.

LEED
We had our first official LEED preliminary rating meeting Friday. This is where we sat down with Eli, our LEED rater, our landscape architect and our mechanical contractor. We’ve already done the design charrette and this is to make sure the major players understand the ground rules for LEED and also what we expect. Third party verification requires some stringent guidelines and we want to do it right from from the beginning. We should easily make Platinum on each house.

We discussed the mechanical systems and how they needed to be designed and installed. The way we are insulating our house, we are foaming the tops of the roof rafters so the heat pump indoor units and the ductwork will be within the conditioned space. That way we don’t have to insulate the ducts and it also makes the system run much more efficiently. We’ll still seal the ducts (the major area of mechanical system inefficiencies) and everything will be ceiling-fed.

We’re thinking the cottage will use a mini-split unit, or ductless heat pump. This is much more efficient, especially in a 776 sq ft house. The main house will have a conventional heat pump, but just a very high efficiency one.

Our landscaping is all low irrigation demand. We discussed at length eco lawn versus regular turf versus synthetic turf. We have just about 3% lawn area, but LEED, to maximize the points, doesn’t allow irrigation or mowing, otherwise you lose those two points. I’ve said all along we won’t chase points, but this is an area we want to be sure we do it right and also have something we will enjoy. An eco lawn in the location we have this might not be what we want. Our landscape architect suggested a synthetic lawn (I know, my first thought is “Astro-Turf“). We are going to go look at one here in town, but I’m skeptical about it. The term “Fake Lawn” is what comes off my lips. I’ll keep you posted.

SUMMARY
So that’s where we’re at. I’m hopeful we’ll have the bids come in well and we can get this house sold and start building. The prime building season in Eugene (March – September) is fast approaching.

my aha moment

A couple of weeks ago, Mutual of Omaha came through Eugene. Someone from their organization had wandered across our website and contacted me about recording my “aha moment”. I thought, “why not?”

So, on a warm, sunny August day, in an Airstream trailer in downtown Eugene, I spent a few minutes chatting with Jessica Henry and recording a snippet of what started stirring in me in late 2008. It was that “stirring” that led to the beginning of thesimpleHOUSE and our whole concept. You can watch my aha moment at

my aha moment

Let me know what you think. I’m usually fairly calm in front of people, but found myself a bit nervous with lights, camera and microphone. It was still a great experience, though and I’m glad I did it. It’s always good to tell your story and fremind yourself just what it was that brought you to the point you’re at.

theFERN – latest picture

stucco and roof are on theFERN in Marathon, Texas
Steven Jones sent us the latest picture of his version of theFERN that he’s building in Marathon, Texas. His comment: “I love it!”
Thanks, Steven, we’re looking forward to seeing it completed.

The Lawrence Street House – Solar Electric [update]

[added revised pricing on solar hot water system and total cost; even better than I originally thought]

In addition to thinking about our landscape design, finishing the structural plans and selecting some of our finishes (more on those to come), we’ve been looking at our solar configuration(s).

Typically, you’ll do a 2 or 3 KW photovoltaic and a separate hot water system. This maximizes tax credits and utility incentives and generates a lot of electricity and hot water. Photovoltaic systems are still expensive and the cells are getting more efficient, but they’re still relatively inefficient. HOWEVER, they are still worth it in my book.
Hot water systems typically generate a lot of hot water for a relatively low cost. As a point of comparison, a 2 KW equivalent hot water system will cost about $8,000 to $9,000 where a 2 KW stand-alone pv will be in the $13,000 neighborhood. Both of those are before credits and incentives.
But our LEED rater, Eli, has a friend who is an engineering type who had a thought. This, of course can sometimes be dangerous (engineers having thoughts can be kind of like architects having an idea). But the more I’ve considered his thought, the more it makes sense to me.
What he observed is during the summer, a typical solar hot water system will heat a normal 120 gallon solar water tank up to maximum temperature, then shut off. Two “problems” with that. First, 120 gallons is more water than most people use (a typical home has a 52 gallon water heater). Second, when it shuts off, in the time of year when you get the most solar, you are basically throwing away that extra energy by not collecting it. Two very intriguing points.
So his thought is to bag the solar hot water system with its oversized tank, pumps, plumbing, etc and put that money into upsizing your photovoltaic system. So I got some preliminary pricing on upsized pv. A 2.1 KW system is about $13,500 ($1,200 net after credits), a 3.2 KW $20,000 ($4,500 net) and a 4.9 KW system $29,400 ($9,500 net). A hot water system nets out at about $4,200 after credits. So a 3 KW plus hot water system nets at about $8,700 but boosting it up to almost 5 KW (3 KW plus the 2 KW hot water) nets at $9,500. And, during the summer, we can sell the extra back to our utility and build a credit for the winter.
We’re strongly leaning toward the 4.9 KW system. We’ll couple that with a small, 40 gallon high efficiency water heater (like the Rheem Marathon). I have Eli checking to see how much energy we should actually save (which is more important to us than the tax credits) and I’ll report how that pencils out.

theFERN – Marathon, Texas

Here are some pictures of Steven Jones’ progress on theFERN that he’s building in Marathon, Texas.

He is using SIPs panels from EH Systems (http://www.ehssips.com/) and their panels will be featured in the Easter Edition of Extreme Makeover Home Edition on ABC.
I’ll be posting more pictures and following Steven’s progress as he builds theFERN. I’ll also be uploading to our website more pictures and information for you to see.
The beauty of the SIPs is these exterior walls and roof panels were installed in two days.

The Lawrence Street House – LEED for Homes

We have officially registered our home with the US Green Building Council. This is the first step in pursuing LEED (Leadership in Energy and Environmental Design) Certification.

In addition to this registration, we hire a LEED rater — Earth Advantage from P-Town. Our local rater is Eli and he worked with us on theSAGE.
He is starting some preliminary calculations for the building shell (walls, floors, roof insulation and windows) so we can establish a baseline of where we’ll be for energy efficiency.
One concept we’ll be incorporating throughout is the idea that the most efficient heater, the most efficient light, the most efficient (insert item here) is the one you don’t have to use in the first place. This saves on many levels: initial cost (you don’t buy it), operating costs (you don’t use it) and maintenance costs (if it ain’t there, you don’t have to fix it).
I do have to insert here that there are some up front costs associated with some efficiency measures (extra insulation to reduce heating and cooling needs). But in the overall life-cycle cost of a home, only about 10-15% is the initial cost; virtually all of the rest (about 85%) is the operating and maintenance costs: paying for the energy to run the furnace or turn on the lights.
So we will be looking at efficiency measures up front. The house is already designed to take advantage of natural lighting and we’re looking at every other component with these efficiency measures in mind.
As an aside, I think we’re going to love our new neighborhood. Brenda and I went down last week to mow the weeds (trying to be a good neighbor), and met our soon-to-be neighbor, Jim. We had a very pleasant conversation with him and I’m sure we’ll enjoy living on Lawrence.
Stay tuned.

The Lawrence Street House – SDU (finally)

Finally. We have the design for our secondary dwelling unit (aka SDU). It’s amazing how challenging it has been to design a two-bedroom, one bath home in under 800 square feet.

City of Eugene code allows for a second dwelling on the same property if the lot is large enough (it is), if the owner of the property lives in one of the houses (we will) and the second house is no larger than 800 square feet (it comes in at a relatively lean 776 square feet).
Having the mindset of small homes and having done this before with theFERN plan, I thought this would be fairly straightforward. Was I wrong. theFERN is a generous 1,024 sq ft. It’s interesting when you get this small how every inch counts even more.
Our SDU is 250 sq ft SMALLER than theFERN. That’s the equivalent of a room 15 x 16 feet. Pretty large. And we still wanted two bedrooms.
After lots of pushing and pulling, reviews, sketches, redraws, redesign, hair-pulling, we feel we have a really good plan. It blends well with our main house and will have similar details. You can download a larger pdf version of the picture by clicking here.
I’m actually very happy with the way it laid out.
AND, we met with our Landscape Architect yesterday and he’s starting on the site/landscape. I’ll talk more about our design goals and philosophy about the landscape in a future post.

The Lawrence Street House – Refinements Pt 2

We have refined the exterior as well as the floor plan and are now very happy with every aspect of the design. Click here for a larger image of the south elevation.

We’ve added arbors over the south windows at the living room and over Brenda’s potting bench area off the garage. The front porch is reminiscent of the Craftsman Bungalow houses from the early 1900s. We want to blend in with the rest of the neighborhood. We also want to capture the front porch concept that is missing in our culture. More on that later; this is something stirring deeply in us.
I’m also meeting in a couple of days with our LEED Rater to get started on our LEED certification. And, I’m now starting on the design for the Secondary Dwelling Unit that will be located along 15th by the alley. More as that progresses, too.
We’re getting more and more excited about our new home!
