New Construction Home Size Adjuster removed

We have removed the new construction home size adjuster and instead created a New Construction credit. Now, just like when selecting the project (remodel, addition, etc. Project cert project level, you can simply select new construction and desired certification level. This remains in section 1 but has been moved to the over prerequisite category.

Home size credit moved and updated. New added square feet credit removed

The Home Size credit has been updated to rewarded smaller homes all the way down to “tiny home” size starting 750. We also removed all health and water credits associated with this since those have little to do with home size. This credit now also applies to new homes since the home size adjuster was removed. Note this credit had its category along with with the credit that rewarded for not increasing square feet in a remodel. It has now been moved right into the 2.2 Design section. Also, we have updated the language to reflect how to measure a home which now under ANSI Standard Z765-2003. Multifamily projects will use average unit size for this credit.

Numbering is fixed!

It has been a long time but yes, the numbering is finally all matched up. Also, several sections have now changed what their numbers use to be. If you create alternative documents, it always best to name the credits too, just so that you can reference it if the number changes. Section 1 is now overall prerequisites (use to be section 2) and section 2 is now preconstruction design strategies (formally Section 3) and so on. Also, Air leakage reduction has been moved in section 2 and some sections in finishes and materials have been moved to lower numbers, properly ordering that section.

WaterSense water budget tool & drought tolerant plants

Drought tolerant / Native plantings have been moved out of Irrigation and moved to Plantings/trees section. Also, this section was updated to award Land (place) points for these categories, and the section was expanded to rewarded for 30% of the landscape incorporating these plant types. – 3.3.6 Plantings have been removed because of this Water sense water budget tool has been incorporated into the program.We have been altered to the fact that in some cases greenstar rewards more for irrigation system vs having a landscape plan that does not require irrigation. This is one of the efforts to fix that issue. You can now collect more points for achieving 60% or more of a reduction below the baseline of your project type. This already rewards for Land (place) points at higher levels since those will require native/adaptive plantings.

Greenstar Qualification opportunity update

We have updated the online on-demand education to become Greenstar qualified. The idea is that anyone looking to certify a project should have a very basic understanding of the residential green building. The course you need to take is called The Basics of Residential Green (Re) Building & introduction to GreenStar Homes certification. These two courses total 4 hours of education and two open note quizzes that you can take at your own speed. Use coupon code GSHqualified to get 75% of the course(s) costs. Both of these courses can count toward your GreenHome Associates, which can get you more credit in the system. Remember this is just of the four ways to get qualified.

PS: Radon only needs to be tested on homes without systems. Currently, you do not need to test homes with passive systems but it is highly recommended. Here is a very neat resource on Radon for your clients.

Michigan GreenStar’s First Certified Remodel in Grand Rapids

Post author By admin
Post date October 28, 2015
No Comments on Michigan GreenStar’s First Certified Remodel in Grand Rapids

Being the Executive Director at an organization that promotes and trains on residential green building, Brett Little decided to put his money where his mouth was and commit to green remodeling in his first home purchase. Brett and his wife Laura wanted to commit to the up and coming city of Grand Rapids Michigan, which was easy to do with all the past few years of recognition and grow (Most sustainable mid-sized city, beer city USA 12′ and 13′, top ten place to find a job, most LEED building per capital and etc etc. ). The project is a prime of example of how one can use GreenStar on a small remodel / weatherization job without being too invasive to the home.

The 2 story house circa the 1920s was aesthetically in great shape, had a newly remodeled kitchen, intact wood windows and trim, good paint, half finished the basement and very well kept landscaped (turf) yard.

What the house was missing was quickly shown in the inspection and energy audit. They revealed a lack of any decent insulation/air sealing, chuck full of incandescent light bulbs, inefficient water fixtures, noisy bath fan old and oversized heating/cooling systems along with a dinosaur of a water heater and no garden in the perfectly south facing fenced in backyard.

The target was LEED Silver certification through a Gut Rehab, but we quickly had determined that exposing the exterior or interior walls to air seal plus removing the shower and tub surround to add in a non-paper face drywall would go way over our budget. While LEED may fall more in line with a Deep Green Retrofit, we opted to do a Moderate Green Retrofit.

From there it was clear that the once called MNGreenStar program would make the most sense and they used it to document the existing conditions and come up with our goals to make the home better. As you can see in the initial energy audit in which they used was the HERS Model (think an MPG sticker for your house) and came out at 175. You can see a little more on results we got here. This number was on track with the old homeowners energy bills which we acquired during the audit. Their overall order of importance to the home upgrades was Energy Efficiency, Indoor Environmental Quality, Water Conservation, Landscaping and then Material Conservation.

They came across a unique financing that allowed them to do a lot of work in the up front while getting a longer return on investment, MI Saves had partnered with their gas company DTE to allow a $2,500 kickback to those who could show a performance plan of gas savings of 30% with an upgrade. Trane/WellsFargo also had a fantastic deal with a 0% 5-year loan that allowed other products outside of their brand to make up 50% of the costs.

Key achievements for GreenStar Certification

Insulation + air sealing
- R 38 Spray foam in attic – Foam had cane/beat sugar components
- Closed-cell Spray foam rim band joist and 1/4 of basement wall
- 4 inches of Rigid Cellulose called Eco-Cell on basement walls
- Drill n fill cellulose added in the empty walls
- Caulking and Air sealing the windows and trim
New Storm Windows
New fiberglass energy star door + weather stripping old door
96% Efficient, modulating and right sized furnace with ECM
90% Efficient Hybrid 20-gallon water heater
Sealed all exposed ducts and hot water pipes
Programmable Thermostat
Mostly LED’s, some CFLs with some Dimmers or Motion sensors
Air changes per Hour (ACH): 5.1
Final HERS: 65
Final Energy Performance Score: 24,000 KWHe
Home Energy Score: 10
181 Points in E.E
Ultimate Air Energy Recovery Ventilator (ERV)
New Panasonic Exhaust Fan
Closed Combustion Furnace & Water Heater
Vented Hood Range
No VOC Paint In Basement
MERV 10 Filter
Asbestos Removed from heating ducts
Radon Test (negative)
Whole House Carbon Water Filtration
46 Points in IEQ
Water Leak Test
.5 GPM Bathroom Aerator
1.6 GPM Water Sense Shower Head
Niagara Stealth Toilet at .8 Gallons Per Flush (half of a normal toilet!)
Plan to not water lawn during the day
Reduced Turf
28 points in water conservation
Installed Food Garden & Raised Beds
High Walkscore of 80 out of 100
Compost and Recycle almost all waste through the city & organic cycle
24 points in Site and Community Impact

Because this was a light remodel and weatherization they did not score too many material points. Materials are mainly for extensive work being done and refurbishment in existing homes.

To see the entirely completed checklist, go here and download it or view it online

Our blog details 1 years worth of utility date & costs associated with the project. It also features lessons learned. They will be keeping it up to date by monitoring the performance, durability, comfortably and maintenance.

They plan to achieve Silver Certification within 2 years by converting more of the backyard to a food garden and the entire front yard over to a mix of drought tolerant and native plant species along with raised bed food gardens. Adding rain barrels and fixing the gutters. We hope to achieve more points by painting the exterior of the house with carcinogen free no VOC paint.

Other current issues – No return ducts in the 2nd floor and some older ducts still panned in the joist may be causing temp swings in the second floor and higher summer humidity. We have an idea of opening up the kitchen to connect to the living and dining and during that time we could potentially add return ducts and seal the current ducts.

Passive House in the Woods – GreenStar Gold

Post author By admin
Post date July 27, 2015
No Comments on Passive House in the Woods – GreenStar Gold

The Passive House in the Woods [Konkol residence] is a single-family home located in the Town of Hudson, Wisconsin. Located on a one-acre lot on the outer edge of a residential development the home overlooks the St. Croix River valley. The building lot provides stunning views and prime passive solar exposure. With its renewable energy systems, the structure makes more energy than it consumes. It features three bedrooms and three levels, including a walkout basement, as well as a rooftop terrace.

The insulated concrete form substructure was built in the winter of 2009/10, and the home finished in September of 2010. The project is Wisconsin’s first certified Passive House and at the time, one of only a handful of certified Passive House projects in the United States of America.

The building envelope of the Konkol residence is very uniform. The below and above grade walls are made from the same insulated concrete form (ICF) assembly with exterior insulation and finish system. The basement slab rests on foam insulation—the roof deck is topped with foam insulation. The continuous concrete pour inside the ICF forms offers tremendous strength and helps with airtightness. R-values are very high and continuous. Both the garage as well as the exterior steel stair and deck structure are self-supporting and do not interrupt the building envelope.

The North side of the home is largely covered by the garage, which is essentially built up to the home but does not share any assemblies with it—making the house’s envelope continuously the same. There aren’t any windows on the North side at all. The south side opens up for maximum solar heat gains, which are managed by motorized exterior shades.

Covered entry and garage access are located on the main level from the East. The main stair is located along the North wall with storage cabinets lining it on each floor. The main level holds the kitchen, dining, and living area, as well as a powder room. Storage, mechanicals, and a guest suite/ family room are located on the walkout level, which provides access to the backyard.

The upper floor contains two bedrooms and a joint bath/ laundry room. Both the main and upper floor offer access to the exterior decks on the West side, as well as the exterior stair structure on the North side, which connects all levels from the ground to the rooftop terrace. The rooftop terrace holds part of the photovoltaic system and the solar thermal panel. It offers spectacular views over the St. Croix River valley.

The building was designed from the outset to become a Passive House. The first energy model was completed during schematics and subsequently kept current with design evolutions. The construction methods were selected specifically with airtightness in mind. Fenestration and glazing were fine-tuned using the energy model.

In an effort to deliver a holistic and sustainable design, the building was also designed to meet the Minnesota GreenStar Gold level of certification focusing on energy efficiency, resource efficiency, water conservation, indoor environmental quality, and site and community impact.

Fast forward to 2015

This project is our first ever Zero Energy Capable Designated home which means it was designed and tested to be a low energy usage home and be completely offset by renewable energy. Not only that but the Konkol family has gone to great lengths to actually prove the home can obtain Zero Energy in their utility bills and have produced 300 more KWH than they used. This is why we are awarding them with our Zero Energy Hero award for the year 2010 – 2015. They produced 300 kwh more than they had used. You can see their energy use and generation here.

Tim Eian, the project architect explains this in more detail.

“In year 1 we identified a couple of commissioning errors, which upon evaluation, were fixed. This lead to lesser consumption in subsequent years. In 2014 we understand that the solar thermal preheater panel failed (after repeated issues with the solar thermal hardware) and it took some time for it to be replaced, during which electric resistance hot water generation caused a higher than normal energy consumption. In addition, the tracker mechanism on the PV array failed repeatedly and is, as far as I know, defunct now, leaving the panels at a static position, rather than tracking. It is very frustrating to see the renewable systems causing many problems but re-assuring for the envelope-first approach we chose.

You will note at the bottom, that despite the issues with equipment, the overall balance for the site as of last month is still net positive. Please also note that the site is on a well with water filtration, which accounts for approximately 700 kWh per year (we monitored this for a few years), which a home on the water grid would not incur. The owner also maintains a large edible garden, which needs watering in summer and fall. The meter is accounting for all site loads, including the water well and filtration system, exterior lights, etc.”

No Comments on Terra GreenStar IL Gold Gut Rehab

This is not your average gut/rehab by a “flipper.” It’s IL’s 2nd Gr
eenStar Homes Gold Certified remodel project seeking to preserve and re use a home instead of building new. This home was featured on the 2014 GreenBuilt Tour in IL. At Terra Green, they follow two basic rules: If they wouldn’t put it in their own home, they won’t put it in yours; and they’ll make the home as affordable and green as possible. First they started with a team effort that took different skill sets to go around the room and determine the best goals for the project and then after the project held post construction team meetings to discuss issues and lessons learned. This type of exercise is important to ensure homes meet green targets throughout the process as well determine what can be done better on the next.

This home focuses on a tight building envelope, energy efficiency and high indoor air quality. Air changes per hour were 30% better than code at 3.14 ACH through advanced air sealing techniques, a self closing door to the garage prevents exhaust from entering the home. No carpet along with Zero VOC finishes and adhesives, MERV 12 air filters, no formaldehyde cabinetry, GreenGuard certified kitchen countertop, duct cleanings, sealed crawlspace and duct joints and radon tight sump dome with a radon mitigation system also help aid the improved air quality of the home. Other improved health and comfort features include keeping major electrical loads away from bedroom, sealed ducts with mastic and there were fully ridged and located appropriately for air distribution.

The builder highlights many little things that add up to a big improvement: caulked penetrations, Energy Star windows, heavy insulation, high-efficiency heating and cooling, ceiling fans, Water Sense certified fixtures and all CFL or LED lighting. The windows were repaired and resealed as opposed to replaced. A 16 SEER HCFC A/C was added for improved comfort, efficiency and reduced global impact.

The site itself features landscaping that helps reduce cooling load and implements sidewalk shading and a roof water drainage system catches 20% of storm water run off. Grading and slopes are used through out the site to protect the home from potential water damage as keep a home dry is the 1 green application you can implement on an existing home.

Rural Homes can be Green too!

Post author By admin
Post date January 5, 2015
No Comments on Rural Homes can be Green too!

Sometimes in the Green Building world we look to the urbanization of homes and buildings to improve location efficiency and give the benefit of community connectivity. Often times we may view homes that are suburban or rural to not be green because of the dependence on the automobile to access resources that are often times miles apart. We know of course that when purely looking at energy, a more rural built home still can meet or even surpass an existing urban home by taking a few more extra energy additions to offset the use of vehicle miles. We also know that more energy is used in homes vs the average consumer vehicle and so there are many opportunities to build better and make up for this.

Thanks to our in kind sponsor Building Efficiency Resources to make this possible!

When MI’s first GreenStar Certified Gold Home was completing their certification they found that their site and community impact score was just a few points shy of gold, mostly due the fact their home was located in the middle of the woods in the Manistee National Forest. In contrast we found the energy score of the home to be surpassing gold requirements greatly. The team made a request to see if their energy score that resulted from a HERS 16 and both solar pv / thermal could be a justified trade off for the energy the average family would need to access resources in a more rural area. The GreenStar tech committee and review (Marc Sloot) got to work right away investigating the opportunity.

The goal of the research was to determine what the average family in the average vehicle travels per year in an area identified as rural and then determine what the predicted energy usage of the HERS index is per point and find a way to offset a better HERS index for a trade in SC (Site & Community impact) points.

Researching data on energy used in vehicles for rural families was easy but determining energy usage per HERS index point was not. The HERS index score is not meant to necessarily be something that predicts energy use directly but rather something to compare differently built to code homes. We reached out to Building Efficiency Resources (The BER), one of the leading HERS providers in the country to see if they would help us extrapolate data. This data would includes HERS index, square feet, climate zone, remrate predicted energy usage and number of bedrooms. Eurihea Speciale, founder and principal was gracious enough to provide 550 sets of data for Midwest homes and the Neighborhood Energy Connection (NEC) in St Paul MN provided another 50 but was skeptical we would find a correlation between HERS and energy usage.

Marc Sloot and the Tech Committee were able to come up with somewhat of a comfortable number that showed a reasonable energy usage prediction per verified HERS Index point and while there were many outliers it served the purpose we needed. After some deliberation the team was able to determine a good set of rules for more rural projects who achieve advanced energy scores and low HERS ratings.

GreenStar Exchange of HERS index points for SC points:

—> People can exchange 3 HERS index points for every 1 SC point on the GreenStar checklist up to 10 SC
points.
—> SC points gotten in exchange like this plus SC points they already have for measures 1D-3 + 1D-4 + 1D-5
cannot exceed 13.
—> Actual HERS index + HERS index points given in exchange cannot exceed 75.

This request can be submitted any time before certification via the greenstar waiver form on the checklist.

Interestingly enough because of this research the tech committee thought maybe utilizing the HERS index score as their energy performance pathway may not be the best approach. The next goal of the committee is to instead utilize energy (KWHe)/year/square foot/bedroom to determine a more fair score. This would also open up the use of more tools such as REMrate (without HERS), Passive House modeling and the use of existing home tools such as the DOE: Home Energy Score and Cake System Systems – Residential Energy Performance Score. Thanks to the tech committee for their flexibility and understanding. Anyone using greenstar is open to work with the committee to find something that makes sense because the idea of a greenhome is evolving and should not be a set of rigid and unchanging principals.

Stay tuned in 2015 for more on this research and an update to the energy performance pathway in GreenStar.

Michigan’s First GreenStar Gold Certified New Home

Post author By admin
Post date December 23, 2014
No Comments on Michigan’s First GreenStar Gold Certified New Home

Marsha Traxler Reeves and John Reeves, Homeowners

During the time when Marsha & John Reeves were in the market for a new home after deciding to move from the Ann Arbor region, they happened upon a green home educational session put on by the SE region’s sustainability design expert, Michael Klement. There were sold from there.

“According to my teachers, the two primary guidelines for being a good person in the Anishinaabe world are: 1. Don’t take more than you need, and 2. Don’t waste. Since I am always working to be a good person, it was essential to follow these guidelines in building a house. Green building helps people to avoid taking more than they need and to avoid waste as much as possible. We are blessed in this part of the world to have people with a great deal of knowledge and experience in green building, so the choice to build ‘green’ was easy.” – Marsha Traxler Reeves, Homeowner

It was no surprise that when choosing to move to Newaygo, the Reeves contacted Vos Energy Concepts, a small residential construction company in Rockford that only commits to building green homes. The home the Reeves wanted to build was no ordinary new home. It was to be located in the Manistee National Forest on acreage connected to the beautiful Muskegon River – and the goal was preservation. The project removed neither heritage nor important trees from the site. Dan Vos, a builder from Vos Energy Concepts says: “Small tree logs from the land were split in half, left with bark, and were placed inside between the window frames. Support posts for the patios and entrance roof on the home are logs also from the property.” In addition, rainwater will be captured on site with rain barrels. The water will be used to water the medicinal plants that grow around the house along with the gardens. The gardens are not conventional, rather, they follow the practice of huglekultur. Huglekultur is an alternative type of raised bed garden system that stays fertilized and moist from a decaying log planted underneath it. Any unused rainwater, because it comes off a food-grade metal roof, will not harm the local aquifer as it immediately goes back into the ground.

Inside the house you will get a sense of biophilliac design elements including use of tree branches, natural shapes, and ample interior natural lighting which provides views of the natural world outside. Many of the materials, finishes, trims, and cabinets were locally made using regionally sourced or reused materials. As the Vos Energy Concepts website states, “Old School chalkboards were up-cycled, cut to size, polished, and placed as the window sills. Small tree branches standing up, stripped, and finished placed throughout the home are used for hanging scarves, wet gloves, coats, baskets, towels, and whatever else needs a place. A local artist, Kendra McKimmy, put together a design of a tree from the shore of Lake Superior. Stones collected by the homeowner and artist were used in the making of this beautiful tree that is located on the bathroom curved wall facing the soaking tub.”

“I believe that there are finite resources for all of mankind. So to be a steward of resources becomes a requirement for all of us. I have 11 grandchildren and 5 great grandchildren that are counting on those of us in the decision process today to make responsible choices in the use of our finite resources. Building green is one of those responsible choices. ” – John Reeves, Homeowner

From an energy standpoint, this home rated at a HERS index of 16 which makes it 84% more energy efficient than the standard built-to-code home. The HERS index score comes from local Energy Rater, John Kuyper, who reviewed all of the components and mechanicals of the home to accurately project it’s efficiency. The super tight and efficient concrete foam shell of the home sits on insulated concrete floors which retain the heat of the sun in the winter. Above the home, the attic is insulated and air-sealed with a reflective metal roof to keep down the heat from the sun in the winter. All energy star appliances and LED lightbulbs are installed throughout and a Heat Recovery Ventilator keeps fresh air circulating in the house while avoiding a lot of heat loss during the winter. The home also utilizes a very high efficiency and sealed wood stove for cold winters and radiant floors in junction with a mini split air source heat pump powered by solar PV and hot water to keep the energy costs down and the homeowners comfortable.In addition to the fresh air, the air quality in the home is not diminished because the home only uses low- or no-VOC paints, primers, and sealants, as well as tiled bath surrounds that prevent interior mold growth behind the walls.

The Reeves joined Consumer’s EARP program and started generating electricity in November, 2013, but didn’t get a statement from them that included generating information until June, 2014. Therefore, they only have information from 5/14/14 to 9/12/14, a third of the year and months with long days:

kWh generated 5/14/14 – 9/12/14: 3923

kWh used 5/14/14 – 9/12/14: 1737

2186 generated above used

They expect to achieve see Net Zero Energy but stay tuned!

The GreenStar process, while being fairly easy to utilize, was made easier by Dan Vos’s experience with building many LEED certified homes. The Reeves’ goals on this project did not align with LEED for Homes, but GreenStar certification made a lot of sense for them. While we approached this home using GreenStar in the middle of the construction period, the reviewers were still able to retain what they needed to verify the home’s completion. “Brett and the GreenHome Institute staff were wonderful to work with! They went far beyond my expectations in assisting us through the application and certification process. Their personal attention to the details of our needs was truly impressive,” said Marsha Traxler Reeves.

You can review all the greenstar details that went into this home here.

Mission Zero Home: A Greenstar Gold Remodel & CE Webinar

Post author By admin
Post date December 7, 2014
No Comments on Mission Zero Home: A Greenstar Gold Remodel & CE Webinar

While sitting in his living room, spending the day documenting his home to verify all the measures and requirements for GreenStar, I showed Matt Grocoff the GreenStar checklist tool and manual to give him an idea of what was needed for his project. After looking through it, his immediate response was, “I wish I would have known about this when I started.”

Back in 2010, Matt began a journey. He purchased a 110 year old home in Ann Arbor, MI that has led him on the international road promoting net-positive homes and buildings. When he bought the home, he reviewed the LEED for Homes program but decided against it. He found it to be too invasive for what he wanted and could afford to do to his existing home. Matt, in partnership with Meadowlark, was a pioneer in the world of Green Home deep energy retrofits in the Midwest and has helped influence what can and should be done to bring an existing home to net zero energy.

Despite lacking a good tool (like LEED or GreenStar), Matt and his family persisted on with the renovation. First they underwent a home energy assessment utilizing the HERS index. The results were off the charts – far above 100. “From there we needed to work backwards. Using the PV watts calculator, we determined we could get roughly 9,000 kwh of solar given size of our roof and available technology. For 9,000 kwh to be sufficient, we realized we needed to improve the home’s HVAC, insulation, air sealing, appliances, lighting and other areas to get us down to that level without sacrificing comfort or a normal lifestyle,” Matt explained. Through the detailed but simple measures listed below, Matt’s home is a proven Net Zero home – even while driving a Chevy Volt and charging it at home! They plan to add a little more PV so that they can update their vehicle to a Tesla and still remain net zero.

One thing that I learned while sitting down with Matt and discussing the push back to an all-electric home is the claim that it’s a waste because of electric line loss of up to 10% energy. Most utilities and even the HERS score incentivize the use of Natural Gas. Matt enlightened me to a partnership between Google and the Natural Resource Defense Council that is utilizing Google vehicles to show major natural gas leaks in gas lines all over the country. These leaks are not accounted for in line loss of energy, while electric is.

Beyond energy, Matt and his family were inspired by the Living Building Challenge (which they are pursuing) and are now, in partnership with U of M Blue Lab Engineering and a Ford Foundation Grant, exploring Net Zero water. The goal is to be able to design a system that captures 100% of rainwater off the roof, stores the water, and cleans it to potable and non-potable standards. The final step would be attaining approval by the municipality to install the system. One interesting challenge the Grocoffs must overcome is that their asphalt shingle roof has been proven to contaminate runoff water toxins such as lead. These toxins are very expensive to remove. However, the cost to seal the existing shingles or replace the shingles may prove cheaper in the long run than maintaining a clogged water filtration system. Another element that Matt and his family are working on is to prevent 100% of the home’s storm water from getting into the city sewer. This could be done partly by capturing water from the roof, partly by adding rain gardens. The most unique idea is a partnership with the city that would replace the sidewalks in front of the house with a system that will direct rainwater from the sidewalk to his rain gardens. If it works, replacing sidewalks this way could model in Ann Arbor and in other cities around the country how to reduce the expense and pollution caused by run off and storm water.

Why water?

Even though we live near the Great Lakes and have access to more water than we need, it’s no secret that quality and quantity of water is diminishing. “While all the news media was going on about California this year, much of Michigan was experiencing a major drought and lack of underwater aquifers. It’s important that we have deeper conversations about water in our state and how to protect it through simple things we can to do our buildings,” says Matt.

Because of Matt’s diligence during the renovation process, his home was easily back certified to GreenStar standards. He blew the gold standard “out of the water.” explained Brett Little. We also are grateful to work with him to develop recommendations for existing homeowners using the GreenStar tool to achieve our new zero energy certification. We are very excited to award Matt and the Mission Zero Home with the GreenStar Gold Type 1 Remodel Certification and to induct him before anyone else into our Zero Hero Hall of Fame. We will be monitoring Matt’s house and following his case study as he supplies us with Return on Investment, future energy use, water use, indoor air quality testing data, and other interesting aspects as he continues to do more to his home.

No Comments on Webinar: How I Made a Million Dollars as a Green Remodeler

Let’s face it, if it doesn’t put money in your client’s pockets, or your pockets, it is very likely not going to happen. Sustainability is just fine as a concept but where the pedal hits the metal is on the accounting ledger. Learn how one remodeler, who refuses to do anything except green remodeling, has built a super successful, industry-leading company, which (even during the down turn) provided ample resources allowing him to take 3 months off each year. How does your vacation schedule look?

Speaker

Michael Anschel, a nationally recognized expert on green design, remodeling and building, writes, trains, and speaks for various publications and events around the nation. He is the owner of Otogawa-Anschel Design-Build–an award winning nationally celebrated design-build firm–and CEO of Verified Green Inc. which consults with local government, product manufacturers, suppliers, builders, and architects on green building. Michael led the effort to develop MN GreenStar, and now serves as Technical Research and Development liaison on the Board of Directors. Called “one of the nation’s most outspoken green building advocates” by MN Business, Michael successfully straddles the building, design, and green worlds by engineering profitability into sustainability.

Learn about you can get involved in a Midwest Pilot launch of the GreenStar remodeling certification program and trainings. Don’t miss the opportunity to learn how you can utilize a green remodeling program that is cheaper and more inclusive than LEED for Homes Gut Rehabs and the National Green Building Standard small projects program.
