West Michigan Organizations Awarded LEED Homes Power Builders

Recently two West Michigan Organizations were awarded the distinguishing “LEED Homes Power Builders Award by the USGBC (U.S. Green Building Council). Through this award and others, the USGBC recognizes projects, architects, developers and home builders who have demonstrated outstanding leadership and innovation in the residential green building marketplace.

The “LEED Homes Power Builders,” was developed by the USGBC to honor an elite group of developers and builders who have exhibited an outstanding commitment to LEED (Leadership in Energy and Environmental Design) and the green building movement within the residential sector. In order to be considered as a Power Builder, developers and builders must have LEED-certified 90 percent of their homes/unit count built in 2015 at any LEED certification level.

One of the great benefits of the LEED certification process is that it can apply to very different projects types. As you will see with the two organizations recognized, LEED certification has important benefits to low-income houses in urban settings to higher end homes in remote settings. Both organizations benefit from using the LEED certification process to add validation to their building efforts and to ensure the homeowner is getting a quality built efficient home.

Cottage Home based of out Holland and Habitat for Humanity of Kent County were the two West Michigan recipients honored with the recognition of Power Builders. While they are in different segments of the development and remodeling of homes in West Michigan, both are setting the standard for sustainable building practices.

Habitat for Humanity of Kent County  is on their way to completing 150 homes and counting in the Kent County/Grand Rapids area that has achieved some level of LEED Certification.  Corri Sandwick Home Performance Coordinator for Habitat for Humanity of Kent County stated that the organization started seeking LEED Certifications in 2006 and by 2007 all new homes built were LEED Certified.

Recently, they have been one of the first builders committed to building according to the new and more stringent LEED v4 criteria even before it had been fully finalized. Sandwick said it started in partnership with Grand Rapids Community College Residential Construction Program in celebration of their 100th anniversary. The two organizations decided to try a v4 build. Once they accomplished that build, Habitat Kent decided to build all future homes to the same criteria knowing it would soon be the standard. To date, Habitat Kent has completed 10 LEED v4 certified homes.

Habitat Kent has aggressive goals in the future both related to  LEED but also participates in programs such as Energy Star.  Habitat Kent is also considering the benefits of getting involved in Zero Energy Ready and the EPA’s Water Sense Program. Building homes that are sustainable just make sense for Habitat Kent. It sets homeowners up for success, keeps costs down for homeowners and aligns with Habitat Kent’s partner organizations’ principles. Habitat Kent states that by being wise about green building, they include only what will be most beneficial to families. This creates a healthful environment and drastically reduces energy and water use, saving Habitat Kent homeowners thousands of dollars. For a family of four living on $30,000 a year, reducing their utility bills to an average $105 a month goes a long way in helping them be successful in their home.

Cottage Home based out of Holland is the other recipient of this prestigious title. According to Jeremy Vaneyk construction manager, they started building based on LEED criteria in 2008 and to date have built 100 sustainable homes along the lakeshore. Vaneyk also said that 31 homes have achieved a LEED certification with 13 of those homes being Platinum certified. Building sustainably is very important to Cottage Home. Both Vaneyk along with Founder Brian Bosgraff both live in LEED Certified homes and can use their experience as builders and homeowners to help their clients. Cottage Home strongly believes it is their responsibility to build with the environment in mind. The LEED certification process provides their clients with a validation that their home is being built to some of the most stringent standards. LEED certification is one of the many tools they use to build focusing on air quality, energy efficiency and site preservation as a core foundation of the build. It is much more than a certification process to Cottage Home but more of a business philosophy.

Both Cottage Home and Habitat for Humanity of Kent County are equally passionate about green building and both use the LEED Certification process to set the bar for sustainable building in West Michigan. Their business while different in many regards is also very similar in others. They both show a strong desire to build with the environment in mind and factoring in their homeowners wants and needs.

LEED has become the world’s most recognized rating system for green buildings. The LEED for Homes rating system was created as a way for single-family homes and multifamily buildings to achieve LEED certification. LEED for Homes projects undergo a technically rigorous process to become certified, including multiple on-site inspections and diagnostic tests. According to Green Home Builder, more than 230,000 single family and multifamily units are certified or registered. USGBC is working to make the LEED residential program even more accessible and utilized by builders, developers, and architects. LEED v4, the latest version, will be required for new projects certifying after October 2016. USGBC’s recent Green Building Economic Impact Study found that the residential green construction market is expected to grow from $55 million in 2015 to $100.4 million in 2018, representing a year-over-year growth of 24.5 percent.

Catch the 30 min webinar here 
Download the slide handouts 

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.

Grand Teton Eco-Smart Home goes LEED Platinum & Zero Energy Capable in IL

DJK Custom Homes has launched their line of “Eco Smart Homes” Committing to LEED certification and Zero Energy Capable design and construction practices.

This first home located in Naperville, IL is a Rustic mountain lodge style design with a low Home Energy Rating Score of 10! The project design shows the home should produce at least 3,000 kwh’s a year more than it uses. You can learn more about the project here, see videos, photos as well as other certifications and awards.

Zero Energy Capable certified homes have been designed, built and 3rd party tested to ensure that if operated correctly can produce more energy than consumed over the course of an average year.

We will be tracking this home for a year to see if they achieve the zero energy hero award by review actual utility data and we will be following their latest project for the 2nd home to achieve these goals.

 “Some of the key energy efficient features of this project include LED lighting fixtures, Energy Star appliances, induction cooking, and a 11 kw roof mounted solar PV system. The home is super insulated with blown in cellulose in 2×6 walls as well as two inches of foam on the exterior of all walls.

Maintaining a healthy air supply will not be a problem at the DJK Eco-Smart Home! A combination of No-VOC paints, stains, and finishes are utilized throughout the home, as well low  formaldehyde emitting materials and VOC eliminating drywall. The air will be continually filtered and exchanged with the Merv-13 filtration and ERV system.
Other attractions of this property include an onsite edible garden, a certified wildlife habitat, and a multitude of renewable energy sources. This home has everything you need to foster the perfect sustainable lifestyle you’ve always dreamed of.”  Green Built Tour Posting

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.

Little House New Pic

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.

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.

Green Homes for All: Combining Environmental Sustainability with Accessibility

As we celebrate the 25th anniversary of the Americans with Disabilities Act (ADA), there is plenty to be grateful for. Commercial and multifamily buildings around the country and around the world are more accessible than ever for people with mobility impairments of all kinds. These increases in accessibility are crucial for an ever-increasing segment of the population: Nearly 20% of Americans have a disability and as the population ages, the percentage of people with disabilities will continue to rise.

But the ADA has limitations, and chief among them is that it applies only to multi-family and commercial buildings – not to single-family homes. Millions of new and existing single-family homes are designed in such a way that a person with a disability can’t use them without making significant – and costly – modifications. Which is why we are so excited to see the progress being made in Ohio and around the country related to accessibility in single-family homes.

A bipartisan bill recently introduced in the Ohio state legislature would provide $5,000 grants to homeowners and contractors who need help making homes more accessible. There is also progress on the federal level. “Mark and I are excited to learn that federal legislation has just been introduced by Representative Jan Schakowsky (of Illinois). This would require new homes built with federal dollars to meet accessibility standards – including a zero-step entrance, wheelchair accessible doorways and bathrooms, and climate controls that are at a height reachable from a wheelchair,” says Rosemarie Rossetti, an activist who pushes for more accessible single-family homes.

Everyone benefits when homes are more accessible. When Ohio State University and the Ohio Development Disabilities Council surveyed 250 residents about their feelings on accessibility features like wider hallways, sloped entrances and no stairs they found that buyers would be willing to pay nearly $15,000 more for an accessible home, and that accessible homes sell quicker. The same features that make homes accessible for a person in a wheelchair make a home easier to navigate with a child in a stroller, as I discovered after becoming a father.

As part of the same study, researchers also surveyed people who work in construction. They found that making a new home accessible added, on average, less than 1% to the total construction costs, and costs $4,000 less than retrofitting a home later.

homePageStatic

At the GreenHome Institute, we are working to integrate accessibility, universal design and assistive technology into green home programs. Green homes are healthy, comfortable homes; Healthy homes should be accessible to everyone, regardless of mobility limitations or age. It’s important to educate and encourage builders, designers and architects to design new homes in an accessible way. It’s equally crucial that we provide resources and guidance to help make existing homes more accessible during rehabs, renovations and additions.

We have been lucky to have the help of several experts in accessibility. First of all, Rosemarie Rossetti, who uses her own story and her LEED-Silver-certified home to raise awareness about both green building and accessibility. Our board member Ramesh Gulatee is an architect with LifeCare Design Studio and specializes in designing buildings that meet the needs of people with disabilities. He has always pushed us to make accessibility a central part of our green building program.

We have also been working with the Disability Advocates of Kent County, who developed the first national 3rd-party verified accessibility certification program called ZeroStep. National green building organizations are taking note: The U.S. Green Building Council offers an innovation point to buildings that meet “Design for Adaptability” guidelines, and ZeroStep guidelines are part of the  GreenStar Homes Certification. The GreenStar tool includes a downloadable ZeroStep guidance checklist to help green builders meet accessibility standards.

Next Steps

 We have several resources available to green builders who would like to integrate accessibility for people with disabilities into their designs.

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.

Dining-Phwoods

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.

Zero Energy Hero Award Konkol Residence

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.”
