Brawn vs. Brains

Posted on November 16, 2012 by ellen

If one room at a time was the plan, then the whole room would have to be demolished, including removing the concrete floor, the next step was renting a huge air compressor and jackhammer to get the floor out. Immediately had to return the 90 lb. hammer and trade for the 60 lb. which I could barely handle. After several days of short sessions of rat-a-tat-tatting, it was clear that the work was too brawny and brains would have to intercede. The emphasis turned to going beyond the first room to tackle the larger project by first removing the living room woodstove and breaking up the platform before the jackhammer and air compressor were returned. The $500 brawn experiment was mostly successful because it required a decision to change course.

Can we do it?

A Summer of Deconstruction

Posted on November 15, 2012 by ellen

The summer months were spent tearing out the walls and some of the drywall in the house. Most of this work was done by me in one or two week visits to Colorado.

This is what the house looked like inside in April.

Why Seven Months Later?

Posted on November 15, 2012 by ellen

What happened?

The Design Charrette was a big disappointment for me. I can say that now after months have gone by and some work has gotten done on the house.

Each of the players did bring their expertise to the table, however, it did not appear that any one expert was all that interested or felt able to comment on the expertise of the others. So there was little or no cross pollination of expertise or ideas.

All of the initial participants in the charrette have done work for the project, but more than one person changed jobs and then others finished their work or it is still in process. It is virtually impossible to keep a team together for the entire construction process and have them meet regularly. This idea was an impractical ideal, the reality did not work out for this project.

One of the outcomes of the design charrette was to have realistic expectations of the cost of the whole project. Of course I had nothing but a quote or two for the slab replacement if someone else did all the work, not enough to go on for the project that I was planning. So I had the whole job reviewed by several contractors, and they all thought it was a very costly project. I had no budget to do what they thought needed to be done at the cost they estimated. The most reasonable totals were from Wise Guy Construction and he estimated about $150,000 to redo the slab area of the house.

The biggest barrier to pursuing a LEED gut remodel was what we were NOT prepared to do, given the estimates for the work. That is to also tear apart the rear of the house and expose every exterior wall instead of just the slab portion. Maybe we will get to that step some time in the future, but we are limited to what HAS to be done by our budget, so we gave up on the LEED outcome at least for now.

But I’m going to go ahead and tell what actually happened in the intervening months as I got over the LEED disappointment.

Innovative Design Process

Posted on April 12, 2012 by ellen

Innovative Design Process (ID) is the first requirement in the checklist for meeting prerequisites and gaining points towards LEED certification. As a result of this project’s preliminary rating we have already met one prerequisite for ID and can document most of the rest of the Integrated Project Planning component.

We are also fortunate that we chose a home with the proper orientation and design of south facing windows so these points are practically automatic. We do need to replace the existing solar shading on the home so that will important to document in the remodeling plan.

*LEED For Homes CheckList* *Target performance tier:* *Platinum*
*Innovative Design Process (ID)*
*Area*	*Item*	*Description*	*Max Pts.*	*Preliminary Rating*	*Met?*
1. Integrated Project Planning			11	7
	1.1	Preliminary Rating	Prereq.		March 7, 2012
	1.2	Integrated Project Team (meet all of the following)	1	1
	a)	Individuals or organizations with necessary capabilities			3 members in 3 required areas
	b)	All team members involved in various project phases			Design charrette plan
	c)	Regular meetings held with project team			To be met
	1.3	Professional Credentialed with Respect to LEED for Homes	1	1	Shane Gring
	1.4	Design Charrette	1	1	April 23, 2012
	1.5	Building Orientation for Solar Design (meet all of the following)	1	1
	a)	Glazing area on north/south walls 50% greater than on east/west walls			Photos of south window wall/other windows
	b)	East-west axis is within 15 degrees of due east-west			Survey drawing with N/S arrow
	c)	At least 450 sq. ft. of south-facing roof area, oriented for solar applications			Garage roof
	d)	90% of south-facing glazing is shaded in summer, unshaded in winter			In plan

It is a good thing to start off with easy points as LEED can become pretty complicated. We have completed the prerequisite by holding the preliminary rating meeting. The team is put together representing three areas of required expertise, and Shane, who is a LEED AP for Homes, has been on board since the preliminary rating.
After the design charrette we will need to meet at least monthly while the project is active. Since we are a far-flung team, our meetings will be electronic.
The documentation for item 1.5 will be:

a. Photos of south facing windows (some are hidden by trees) compared to east, north and west.

South facing windows plus one East facing window

Two North facing windows

One West facing window

b. Diagram of home from survey. Shows North intersecting with East/West axis and home axis is about 2-3 degrees East of South, although the courtyard windows curve a bit from east to west none is more than 15 degrees from due East/West.

East West Axis

c.The garage roof is sloped towards the south and could be used for solar panels. There is more than 450 square feet of south facing roof, although part of it is flat. There is no requirement to have solar panels on the south facing roof, just to have this much roof face south–maybe we could have a grass roof in the flat areas!

South facing roof

d. You can see in the above photo that the south facing windows have frames that will accept canvas awnings but we would like to redo the solar shading on these windows. This is a design issue that will be addressed by the architect.

Documentation for LEED

Posted on April 12, 2012 by ellen

Survey of lot lines

LEED projects are all about documentation and verification. It is one thing to say the house is in a developed area or has an uninterrupted thermal envelope and another to document those so that it can be certified as having these desirable qualities.

It is never too early in a project to start collecting this documentation which can be in the form of official documents, photographs, receipts, etc. There are also forms available from USGBC that assist in the documentation process.

In many projects the LEED AP will manage the documentation. That is a service that BOULD offers. However, since we are do it yourself types, I am going to manage the collection and Shane will train/advise me on the process. It will be good to have someone double check that we have the right paperwork.

When the project is submitted by Energy Logic, they and the green rater must sign off on every prerequisite for LEED certification and every LEED point that was achieved. USGBC does not collect the documentation but they rely on the providers to provide verification. This is a strict process that may not skip any steps or the points are lost. Documentation can mean the difference between achieving the level of LEED certification that we are seeking or settling for a lower level.

I would rather have to settle for a lower level because we CHOOSE not to gain a point due to cost or other issues than for a MISTAKE in the documentation! So part of the design charrette is to determine that documentation is being created for each prerequisite and point in the LEED system.

The points are kept track of using a spreadsheet known as the project checklist that was initially filled out during the preliminary rating. I have started the documentation process for the project, the first area being the Integrated Design credits.

Deconstruction–Step Two

Posted on April 10, 2012 by ellen

Not only does Habitat for Humanity build affordable houses for people, since 1998 Denver’s Habitat has been building LEED certified homes that save the homeowners more each year that energy costs increase. Habitat has a lot of experience with recycling materials, using donated materials and providing that service to others through their ReStores. However, some ReStores also use their volunteers to gather donated materials including taking them out of the house for you!

Call for a review of your donation and possible deconstruction services.

I made up this sample sign thinking it would be cool to get one to put out in my yard. However our house is not on a thoroughfare so would not get much drive by traffic.

I had emailed Corey Biechele who is the deconstruction manager for ReStore and he agreed to meet me at the house to review the donations that we could make as a first step towards removing the inside of the house so we can take out the slab. Although the cabinets were quite old and would only be purchased for garage storage, he was so supportive of our plans to build a LEED home and recycle all that we could of the deconstruction, he agreed to bring a team of volunteers over if I would clean all the cabinets and appliances that they would remove.

I was almost sorry I had agreed to clean the cabinets, they were not in the best shape and I kept thinking it was time I could have been playing with the grandkids, but I persevered, and as I cleaned them I reattached some of the fronts correctly and generally improved their resale value all I could.

Clean Cabinets

Corey’s crew removed the oven, dishwasher, stove top, surrounding cabinets and the bathroom vanities, the tub and the shower to recycle the aluminum. He couldn’t take the sink cabinet in the kitchen because the bottom was water damaged. He left us a donation receipt so that we can document that these cabinets were recycled. Actually we have to use their weight for LEED to show they were construction debris that was kept out of the landfill!

Thanks so much to Corey and the Denver Metro Habitat for Humanity!

Habitat for Humanity ReStore

Posted on April 10, 2012 by ellen

Denver Metro Restore!

Throughout our Arizona remodeling work we have become fans of the Habitat for Humanity ReStore both for donations of items we have replaced and for finding materials that have been donated by others.

We have purchased light fixtures, interior doors, sinks, a tub, granite vanity top, hinges, trim, electrical supplies, and that is just what I remember! The way to use Restore is to go often and spend some time looking at what is available so that when a need arises you know what you are likely to find if you need something. I had a list of needs and would stop by once a week or so during the remodeling to see what was available.

When they have a big donation , it can be gone in a day as many area contractors also seem to stop by regularly. Our best “find” was probably 100 or more linear feet of oak door casing, which was used for baseboards in our son’s condo. He decided to stain it mahogany to contrast with the rustic pine laminate floors. Wow, love the look!

Condo baseboards

One of the first places I checked out in Denver area was the H4H Restore website and that is where I read about the Denver Restore’s Deconstruction service!

Deconstruction–Step One

Posted on April 9, 2012 by ellen

Colorado has rules. There are more rules there than we are used to. We knew remodeling in a city would require lots of drawings and permits and inspections and stuff we don’t generally like to do. So the first step was to read the rules for remodeling in Arvada.

As most cities have done, Arvada has generously posted its rules on the city website: www.arvada.org

Prominently featured on that website is the Building Inspection and Permits Link.

I read all the requirements for building permits and deconstruction permits. It appears that deconstruction is major work that involves moving plumbing or electrical outlets. That is what we will be doing when we remove the interior walls and slab, but it did not appear to apply to removing interior appointments like cabinets.

Even though the house was built after the heydey of asbestos use in construction (1984) in order to get a deconstruction permit, the house needs to be tested for Asbestos. Asbestos testing is required not by the city but by the state of Colorado. There is some exemption for private homes but the owner has to certify that the public will not be invited into the home. Since most LEED homes do hold public events at some time, and since we were interested in what the report would say, we decided to look for and obtain asbestos testing for the remodel.

The Asbestos Compliance Assistance Group located on the Colorado state website has lots of good information about testing for asbestos. I called their number and they helpfully directed me to the list of licensed contractors to perform the necessary tests. Contractor may not be the right word since the providers were mostly engineering and consulting firms.

The first provider I called was located in Arvada–that is how I chose him! And he was the nicest guy on the phone so I decided one call was enough and arranged with him to come out and test for the deadly substance. He took a total of 15 samples from drywall, floor mastic, and other house surfaces. And we had a nice chat about living in Colorado and Arvada in particular while he was at the house. It took a couple of weeks for his report to come back and thankfully the house was completely clear of asbestos! Good job Rick Luce!

Freedom Environmental Consultants, Inc

Now we have the signed form that the house is free of asbestos, which will allow us to apply for the deconstruction permit. We just have to have more information about how and when the project will start.

Update:
Turned out that the city said Asbestos testing was a state issue and they did not track it, besides as a home-owner I was exempt. Well, at least I know I was not breathing asbestos during the deconstruction. The initial floor plan and the engineer’s report about the need to remove the slab were sufficient documentation to merit the demolition permit from the city.

Rebate!

Posted on April 7, 2012 by ellen

We received our $180 rebate from Xcel Energy for our $300 Energy Audit. Now we are qualified to apply for other Xcel Energy rebates for insulation and a new energy efficient boiler which this house really needs.

Here is what we are thinking for the energy efficient boiler:

US GSA Energy Recommendations
“Condensing boilers can achieve up to 98% thermal efficiency compared to 70%-80% with conventional boilers. Integrated project design that allow for boilers to be used only as required by demand will yield additional energy savings.”

The Triangle Tube Combination boilers that both heat hot water for the home and for the radiator system are considered among the best.

Triangle Tube Challenger Boiler

We’ll pair this with a solar preheated water tank so we will save even more energy using this boiler system. Plus it fits on a closet wall so we can shrink the utility room from its current 12 x 12 size and use all that re-gained space in the house for living area.

Preliminary LEED Rating

Posted on April 6, 2012 by ellen

LEED Start Up Process:

1. Contact a LEED for Homes Green Rater/Provider (No longer found on LEED site!)

2. Determine if the project is suitable for LEED. For us this was a phone, email discussion. (LEED for Homes Eligibility Guildlines)

3. Register project. (Twinsprings Research LEED project)

4. Recruit a core design team, including a LEED AP for Homes consultant. (No longer found on LEED site.)

5. Hold a preliminary rating with the Green Rater/Provider. (Energy Logic Contacts)

Our preliminary rating was held at the Energy Logic Denver office on March 7th, almost a month ago. The preliminary rating uses the LEED for Homes checklist to discuss the LEED requirements for each point and to begin to think in terms of all the required categories that qualify a project for LEED certification.

I had already used the online LEED Scoring Tool formerly on the LEED for Homes site. There was both a the shorter introductory checklist and also a credit by credit detailed one. I completed both. I was so intrigued by the system that I registered for and took several Online GBCI LEED courses and qualified for the Green Rater course offered by the Energy Logic Academy. Along with several other students from Colorado and California, I attended the course in late February and received a completion certificate from GBCI.

I filled out a checklist of potential LEED points before the preliminary rating but at the meeting it was obvious that Carissa Sawyer knows the system inside and out and has the experience to recommend areas of concentration and advise caution about areas that are difficult to accomplish. Darren Legge was her assistant and also a talented environmental scientist who was finishing his Green Rater internship and will be or is now fully GBCI certified.

Becoming a LEED for Homes Green Rater and perhaps a LEED for Homes AP is a goal that I have set for myself too. I can’t rate my own project of course but this is good experience for future projects and of course to spread the green building word.

Counting the 4 “Maybe” points our preliminary rating shoots for 102 LEED project points just comfortably above the required 94 for Platinum rating for a 2213 square foot 3 bedroom home. (The total number of points for each LEED for Homes certification is figured on the size of the home and number of bedrooms.)

Our Target:

Possible Future?

Integrated Design Approach

Posted on March 21, 2012 by ellen

The Conservation Seeding and Restoration company in Rifle, Colorado became our landscape design partner.

LEED’s approach seems to be to connect people to their living spaces and communities by thinking in terms of people working together and interacting both locally and globally. Kind of a next step towards Utopia, not so much living with one common purpose but being part of a world community in a sustainable, globally responsible but rich in health and energy way. Well, rich in $$ too since the team to help build each individual LEED component is all composed of professionals with expensive educations and the need to survive in this economy.

Being do it yourself owner builders means that we have little to no experience in finding and using building experts. We still want to maintain a lot of builder owner responsibility in the project but there are many areas of LEED that require outside certified expertise. After being educated by EnergyLogic on the USGBC Green Rater requirements, I have a better overall idea of the point system and the requirements for expertise.

We really want to have a small research oriented sustainable urban homestead when we are ready to move in. That includes a garden, small woodlot, orchard, room for small animals like chickens and other food producing mammals. We lived this way in our younger years starting as subscribers to Mother Earth News in the early 70’s and moving to the country in 1978.

As part of this integrated homestead, LEED encourages us to think in terms of native plantings, wildlife habitat, invasive species elimination, reduced heat island effect, less area of expensive grass and more permeable paving and drought resistant turf/plantings. To do this well, and to have an irrigation specialist on the team, I started looking for a landscape company. There were NO companies that seemed to advertise creating such an outside sustainable homestead environment as we had in mind. Although some used native plants, they mostly created little circles of turf and circuitous planting beds with water features, etc. That was not at all what we had in mind.

Carissa Sawyer at Energy Logic suggested that I look at the Water Sense irrigation providers on the Energy Star website. This was not the easiest research since each listing requires that the link open to a small popup window with the company’s information. Terrible design. Why not just let me download a filtered list with all the info into a spreadsheet? Just the provider name and state is useless, the only way to get the detailed info is to open each company link. BUT I was successful in finding just the right company to request for the integrated design team.

Building a LEED Project Team–LEED AP for Homes

Posted on March 18, 2012 by ellen

Everbuild PRO Statistics

Each LEED for Homes project uses the integrated design process to distribute responsibility for meeting LEED criteria and acquiring LEED points. The project team typically includes experts on green building and sustainability and to gain the point for a full LEED project team roster the members must bring to the table expertise in three general areas and must meet monthly to participate in the project. The expertise areas are:

architecture or building design
mechanical or energy engineering
building science or performance testing
green building or sustainable design and
civil engineering, landscape architecture, habitat restoration or land-use planning

Another point is gained if at least one of the members holds the LEED for Homes AP credential and is on the team by the preliminary rating.

I started building this team by engaging a LEED AP architect who has been working in sustainable design for many years. See HumaNature Post

Next I was able to find a Provider in Colorado who can also provide an Energy Rater as well as a LEED for Homes Green Rater at EnergyLogic.

Now I needed a LEED for Homes AP for the team, preferably someone with building science and energy performance background. I was able to turn to the list of USGBC Professionals in the area to choose a LEED AP for homes to contact and ask for help with this project.

Each time I find a professional there is something about their website that draws me in. In the case of Shane Gring’s company, BOULD (Everbuild Pro), they provide LEED training for Habitat for Humanity affordable homes through tuition to the program, you can get the necessary LEED experience and provide support for green building expenses for an affordable Habitat home. Such a GREAT idea! I’m going to sign up myself to help complete my Green Rater credentialing program. BUT Shane also provides LEED AP expertise for independent projects and has a wealth of gut remodel and energy modeling experience.

Where to start? Energy Audit!

Posted on March 18, 2012 by ellen

Deeper Green Energy Consultant

One of the most exciting parts of becoming a LEED project is meeting so many people who are working on sustainable construction and design services. Many are young and just starting their own businesses and they are hard working, dependable, and a pleasure to work with.

At the Green Rater course I met Matt who works up in the mountains for a recycling company that has been around for years. They have been doing energy audits to qualify homeowners for Xcel Energy Rebates but he thought Arvada was too far away for his company to service. So he recommended Melissa from Deeper Green Consulting in Denver. She does consulting in the metro Denver area. You can find Melissa on the approved energy services providers located on the Xcel Energy site.

denver, CO 80219

303-550-7380

The Infrared photo in the header was taken by Melissa for our initial energy audit. Her report entitles us to further Xcel rebates for improving our insulation and other energy efficient upgrades.

Energy Efficiency Rebates from Xcel Energy

Update: Initial blower door test results were 3250 cfm and a NACH score of .43
a. CFM50=3250
b. Volume=24420
c. N-factor=18.5 (One story/normal)
d. NACH= 0.43

Most of the leakage was around the windows and doors so new installations were recommended. We will see about renewing the wood windows first though and resealing their perimeters.Here are the top three recommended improvements; new windows, conditioning the crawlspace, and replacing the old boiler although increasing the attic insulation was also high on the list.

HumaNature Architecture

A LEED project must follow certain guidelines. Some are prerequisites and some gain points towards the level of certification that the owner is seeking. The higher the number of points, the more valuable metal the LEED certification will represent with the most points representing Platinum. Of course there are Gold and Silver, Bronze and Plain certification levels too. Until LEED makes some major changes this year, there are more points available in LEED for Homes than other LEED systems (like commercial buildings which is where they started.)

Of course we aim for Platinum with the goal of having the most energy efficient home, or as close to net zero energy use as possible, but there are several prerequisites just to qualify for a LEED for Homes Gut Remodel that might do us in. One prerequisite is to put together an integrated design team to work together to create a LEED certified house. Finding a team to lend expertise to meet the challenges of LEED has been really interesting.

My first contact was the architect. I just used the Internet to find a sustainable green building architect in the Arvada area who had experience with LEED. Turned out only one really showed up as having these qualities, and I found out he had just moved back to Boulder! But he is willing to travel to work on this project and seems like just the man to have first on the team.

Let me introduce you to James Plagmann, whose award winning designs are cooked up in his company, HumaNature Architecture.

Why LEED?

Posted on March 16, 2012 by ellen

Good question. We bought this house in Arvada, Colorado on New Years Eve 2011. It is earth sheltered on the north and has passive solar windows and a trombe wall to the south. The garage protects the house on the western windward side which is also the hottest.

There are three bedrooms, a family room, utility room, kitchen and living room with two full and one three quarter bath in the master bedroom. Two bedrooms and a bath have a crawlspace under them and are about 3 feet higher than the rest of the house which is slab on grade. It is our retirement project and another step on our journey towards living our homesteading lifestyle.

Since we are working towards sharing our research with the world (Hello world!), partnering with the premier rating agency for Green Building seemed like a perfect fit for this earth bermed, passive solar 80’s home. The original owners were most likely owner builders like we are and we were instantly drawn to the home and its construction.

After quite a bit of Internet reading about LEED, I signed up for a LEED Green Rater course with Energy Logic, which is in Berthoud, Co, about 2 hours from Arvada.

Energy Logic is a Colorado LEED provider and we have contracted with them to rate our project. That was the first step towards achieving a certified LEED for Homes gut remodel!
