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.

Choosing Sustainable Insulation

* Guest post by Emma Pritchard – “Updates by Brett Little in Captions”

Good insulation is an important part of creating a sustainable home design, and of retrofitting an existing home to include more sustainable features. If you’re working with an existing home, there’s a lot you can do to make it more sustainable, and replacing insulation is perhaps the most effective method. Whether you’re doing a remodel or just fitting new insulation, it’s a great opportunity to replace old and outdated materials with new or recycled sustainable ones, or alternatively, those made from natural materials. The initial outlay might set you back a few dollars but since good insulation makes it much less expensive to heat your home, over time, lower energy bills mean you’ll recoup the costs and more.

 The concept of sustainability integrates several different themes:

  • Using renewable energy sources instead of non-renewables like fossil fuels
  • Using non-toxic chemicals in production and processing of goods and services
  • Avoiding practices that harm the environment
  • Adopting practices that conserve resources to ensure they are available in the long term.
  • Maintaining acceptable levels of comfort (for example, in terms of home heating) while keeping to these standards.
  • “Air sealing prior to insulation and making  sure it is appropriately installed too ensure maximum effectiveness cannot be overlooked either”
  • “Insulation affordability is also important to ensure budgets are met”

In terms of insulation, a product is “environmentally” sustainable if it’s made using at least partly-recycled materials via sustainable methods, and doesn’t contain any harmful chemicals. Preferably the insulation should also be recyclable, or the material it’s made from should be recyclable. Another important factor to consider is where materials are produced: to be truly sustainable, insulation should be made locally, relative to where you live. Depending on where you live you may be able to source materials made in your city or state.

 Removing Old Insulation

If you are working with a home built in the 1970s or earlier, or if the current insulation was fitted in that period, it’s important to be aware of the possibility that asbestos might be present either in the insulation or in other building materials. Asbestos is an excellent insulator, but it’s also highly toxic. If your insulation upgrade involves the removal of asbestos, it’s necessary to take precautions to prevent exposure. If you’re not sure whether asbestos is present in your home, and it was constructed or remodeled in the relevant time period, you may want to consider having your home professionally evaluated for asbestos. It may even be necessary to have any asbestos-containing materials removed by professionals to eliminate the risk of exposure.

You may also have other problems to contend with, like exposure to lead paint, or the chemicals present in certain older types of insulation. As well as these issues, most types of insulation have the potential to release particulate matter that can causes irritation when inhaled, so a protective dust mask should be worn whenever working with insulation, even if it doesn’t contain any toxins.

Types of Sustainable Insulation

When you’re replacing old insulation in favor of sustainable insulation, you’ll generally have two main objectives in mind: to use materials with better insulating capability, and to use materials that are free from chemicals that negatively impact the environment. Other considerations will include the production methods used to manufacture the insulation, where it was produced, whether it’s reusable or recyclable, and whether it contains recycled materials.

Loose fill cellulose contains at least 75% recycled newspaper, and it doesn’t contain any harmful chemicals. It’s also made via production methods that use much less energy than most other options, and it can be made locally. “Blown in cellulose can be added wet or dry and can be easy to put in behind the siding of existing homes, this can be done by a professional or DYI interested person who rents a machine”

Cotton is made from a renewable resource, and is typically at least 75% recycled too. It can be recycled, and it’s not treated with toxic chemicals. The flip side is that cotton farming is resource-intensive, with a high level of dependence on pesticides, and climatic requirements that make it difficult to grow in many parts of the world. In addition, cotton insulation picks up moisture very easily and can develop mold. *”Cotton has been associated with fire control problems”

Fiberglass is typically at least 50% recycled material, with some brands achieving 70% to 90% recycled material, and it’s made from silica, which is a naturally abundant substance. However, it’s made using energy-intensive production methods, and some types contain the toxic gas formaldehyde. As well as this fiberglass typically has lower R values than other types of insulation, meaning it’s less effective at resisting heat flow. “Fiberglass tends to get installed poorly on average and in cold weather climate regions has thermal convection looping which means more air loss compared to other insulation” – Brett Little, edit * “Also note that there are blow in fiberglass methods that are easier to install, have higher r value and can be less likely for toxic exposure”

Foam insulation can be tricky—some types are recyclable but some aren’t, and some are treated with highly toxic flame retardants. Most types of foam insulation are made using non-renewable petrochemicals, however, so regardless of any other factors, these can’t be sustainable. However, some types of foam have replaced the petrochemical component with renewable alternatives that include formulations made from sugar beets, sugar cane, and corn, creating products that are less expensive, and more sustainable. “If foam is installed poorly it can be a danger to the installer and occupant as well reduce it’s effectiveness, foam can also off gas during it’s life time, loosing it’s heat resistance properties and reduce indoor air quality in the home.”

 Mineral wool (also called rock wool) is made from rock or steel slag—both abundant natural resources—and typically contains at least 75% recycled material; however, it releases low levels of irritants that can cause problems for people who are sensitive to airborne particles. It’s naturally highly fire-resistant so it doesn’t need extra chemical treatment.

“Strawbale & Strawclay are products made from waste materials from farming and from digging up the ground for new construction builds. These products are mostly used for new homes and/or additions and are natural, non toxic, fire and pest resistant materials if installed properly with appropriate moisture control levels. These products can be more labor intensive but often can result in community building parties that overall improve your fun score! These products tend to be more popular in dryer climates with larger temperature swings as moisture can be damaging to them and they are good at holding heat and letting it off at night when the temperature cools down”

Sourcing Sustainable Materials

When it comes to insulation, it’s relatively simple to buy sustainable, since so many products are made from partly recycled materials. Any home store that carries a large product range should have at least a few that fit the bill. It’s usually easy to tell whether products contain recycled materials, as most labels include this information.

“It’s also makes it easy if you specify only insulation products with 3rd party certifications, look for

Another option is stores like Habitat for Humanity’s ReStore chain, which deal mostly in used building materials, fixtures and fittings, and home accessories. Stock in these types of stores tends to be highly variable, but you might be able to score a great deal and support a great cause at the same time.

Indianapolis Restored Home Gets LEED Platinum & Sells Fast!

Elm St. PICThis home located on Elm St. in Indianapolis, IN was an abandoned space, built in 1910, that was bid on for redevelopment through the Southeast Neighborhood Development (SEND) organization’s Transfer and Transform program, which seeks to reinvigorate the community

Elm St. B4 INT

Interior before


“William Wagnon of Green Path Homes  had been looking for an opportunity to do a LEED Platinum certified redevelopment on a house that could serve as an example of green building for contractors, home owners and a city in need of sustainability.” The house on Elm presented a perfect opportunity to showcase the economic viability of a green project as well as its added health and enjoyment benefits.


No subsidies or donations were taken to help the project along. “We wanted to do it as a market-rate project so that nobody could make an excuse for not doing it. That’s the point I wanted to make,” Wagnon said.

Elm St. B4

Exterior before

“The house now features around $7,000 worth of insulation, putting the home’s heating efficiency well-above most standards. The floor plan was changed to allow for a contemporary living style. Raised ceilings and other space improvements provide for maximum storage in the home. A rain garden now sits at the front of the house fed by a drain pipe from the roof. The backyard deck looks out onto a single-car garage, raised planters for growing vegetables and a patch of lawn.” Additionally, 100% of installed plants were drought tolerant further reducing irrigation needs. In total, the outdoor water savings plus the water savings due to the indoor installation of highly efficient faucets, showers, and toilets etc. results in a monthly water savings of 69% based on total water use. We were able to utilize the V4 Homes Workbook: Water Reduction Calculator to derive this number. A copy of the information is attached to the project profile at the bottom of this post.

Elm St. INT PICThe small 960 sq ft. 2 bedroom 1 bath home is located in an area with outstanding access to community resources such as public transportation. This well sealed home uses energy efficient appliances and  is expected to save 47% on energy bills. Insulated piping adds to the efficiency of this home. 

A central HVAC system equipped with an additional dehumidification mode adds to the health of the home along with the use of hardwood with a preference for FSC certified woods.

So much care was put into this home on Williams blog he writes … “Walter, who has does the exterior sheathing, rigid foam insulation and now the siding work is putting flashing tabs behind each butt joint on the siding.  These joints will all be caulked, but it’s just a fact that caulk fails in a couple of years.  But with the flashing tabs, any water that penetrates is redirected right back to the outside.LEED Label Elm

Brad nailed every shingle of the roof by hand.  Yes, it takes much longer, but he knows each one is set.  In building the soffit end caps, he cut fairly complex pieces so it could be 1 piece of solid wood, instead of having multiple joints that would require caulking.”

This project was the first residential home in the area to achieve the prestigious LEED Platinum certification.

USGBC certifies 50,000th LEED Homes

Quoted text from ” ”

“Since its start in 2007, 50,000 housing units have been certified under LEED for Homes and 44 percent of those homes were classified as affordable housing.” “As one of the most rigorous green residential rating systems in the world, LEED for Homes is the standard against which all other such programs are measured,” said Rick Fedrizzi, president, CEO and founding chair, USGBC. “Despite its demanding technical aspects that set a high bar for green residential construction, LEED for Homes has also seen the broadest adoption among its peers — indicative of its position as the rating system of choice to guide the design and construction of healthier, high-performance homes.””

“Since the launch of the LEED for Homes rating system in 2007, the growth trajectory of the world’s most widely used residential green building program has been dramatic. From 392 housing units LEED-certified in 2007, the figure jumped to nearly 900 units certified within the year 2008 and nearly 3,000 certified within 2009. In 2012 and 2013 alone, USGBC certified more than 15,000 and 17,000 housing units, respectively.”

“Of the 50,000-plus certified units, 74 percent are within multifamily buildings, while 44 percent are classified as affordable housing. In addition, nearly 65 percent of the total units were certified in the past two years, a strong indicator of the continued momentum of the rating system. There are also more than 82,000 units under construction and in the pipeline for LEED certification.”

is excited to be apart of this movement. As an ordinal LEED for Homes provider we have certified nearly 4,000 of these homes with another 3,000 in the pipeline. Learn why LEED excites us. 

“The continued growth of LEED for Homes is attributable to its many proven benefits, including enhanced property value, healthier indoor environments, and energy and water savings that average 20 to 30 percent. LEED-certified homes are third-party inspected, tested and performance-verified, offering homeowners and renters piece of mind that their places of residence are efficient, saving them money and also better for the natural environment.”

“In December 2013, USGBC also announced the LEED certification of its 20,000th commercial project.”
