LEED for Homes - Online Scoring Tool - www.leedforhomes.org

LEED Home Scoring Tool Released

USGBC has created an online tool that will allow anyone to “kick the tires” on taking a single- or multi-family building through LEED for Homes certification. The Online Scoring Tool (OST) is available at no cost through www.leedforhomes.org and provides a great way to evaluate the LEED rating system.

The user-friendly Online Scoring Tool (OST) allows free access to anyone that creates a web site account. Once logged in, people can score multiple rojects using the online scoring tool.

Two Scoring Paths
Projects can choose to take one of two paths with the LEED Homes scoring tool. One path called the Quick Score, allows a builder to answer a green home version of 20 questions about a sample project. Its perfect for a builder that has had a HERS Rating performed on a previous home and is wondering how that home would have scored in LEED. Once the questions are answered, the scoring tool gives an estimate on the potential LEED certification level.

A more advanced path allows the user to go through the LEED for Homes rating system in detail for a specific project, with credit-by-credit analysis. Each credit can be selected as Yes, No, or Maybe.  Best of all, the online tool does an impressive job of digesting the extensive LEED for Homes Reference Guide into salient tool-tip help that can be brought up in a popup window. This explanation will help people decide whether or not they want to pursue a specific LEED credit or not.

The House Basics

In order to achieve LEED Platinum status, Live Green Live Smart/The Sustainable House™ must meet a rigorous set of guidelines that require exceptional attention and innovation on the part of the builders and designers.

Sustainable Energy Systems

The most conspicuous innovations are in the ways the House actively uses (or doesn’t use) energy. Because this is a demonstration project, the House incorporates many redundant energy supplies – it is important for us to show how not just one, but many, systems work and how they work side-by-side.

  • Solar panels provide both electricity for the home and energy to heat water.
  • The Honda/Climate Energy Freewatt™ “combined heat and power” (CHP) system provides, via a generator and furnace run on natural gas, co-generating electricity and forced-air heat.
  • Underneath the House’s front walkway are four 135-foot-deep geothermal wells, which circulate a non-toxic solution through pipes to capture the stable temperatures beneath the surface. The energy of the Earth’s heat is transferred to a WaterFurnace™, which can heat the home in the winter and provide air conditioning in the summer.

Environmentally-Conscious Applications

The green building materials and techniques as applied to the House are less conspicuous than alternative energy sources, but no less important to our Platinum remodel.

  • Efficient insulation and an air transfer system ensure that none of the heat or cold generated goes to waste, and that the air inside the home stays clean and breathable.
  • Solatubes provide natural sunlight all day long, even in the basement, reducing electricity needs.
  • Every lightbulb in the house is an energy-efficient compact fluorescent or LED.
  • Low-voltage radiant in-floor heating is an efficient way to reduce furnace needs.
  • Greywater is collected from the showers for reuse in the double-flush toilets.
  • Windows are triple-glazed and argon-filled to reduce heat transfer.
  • Appliances are EnergyStar rated, and an induction stove is used for cooking.
  • All electrical energy purchased from the grid is the product of windfarming – no coal-fueled energy will be used in the House.

Conservation and Pollution Control

Remodeling an existing home instead of building a new one allows us to keep our construction footprint to a minimum. Remodeling when more usable living space is needed also preserves untouched land, reducing the land and resources needed for specific construction.

  • To rebuild the home we have reused as many of the original components as possible – including the 2×6 studs reused to extend the eaves out from the house to save energy needed for cooling, and to protect sidewalls and windows from Minnesota’s weather extremes.
  • Anything that cannot be reused is recycled – such as the House’s old stucco – and anything that cannot be recycled is handled by responsible disposal to reduce pollution of air, soil, and water.
  • Studs for the new additions (foyer and garage) are 2×4 instead of the standard 2×6. They are also spaced farther apart – 24 inches on center – providing about a 30% savings in new lumber used.
  • Most new wood is FSC (Forest Stewardship Council) certified to come from sustainable forests.
  • Furniture, cabinetry, and countertops are made with recycled or sustainably-harvested materials, and are free of harmful chemicals.
  • Paints and varnishes are free of harmful VOCs (volatile organic compounds) and formaldehyde.
  • The highly efficient insulation is no-VOC, and an energy heel enclosed in an interior soffit minimizes cold and hot air import by protecting the jointure of walls and roofline.
  • Foundation concrete is made with 40% fly ash – recycled sooty waste from coal plants – which is less expensive and more durable than a standard Portland cement mixture.
  • Potable water from municipal supply is further filtered with a purification system.
  • Water-saving devices include automatic on-off faucets, the batteries of which are recharged by water flow through the supply valves, and double-flush toilets that flush once for liquids and twice for solid waste.

Land Management

In meeting conservation and efficiency requirements, what goes on outside the House is equally as important as what goes on inside the House.

  • Rain gardens planted with native plants collect rainwater and allow percolation back into the ground instead of runoff into storm drains. Cisterns collect additional rainwater from the roof and gutters of the House – a two-inch rainfall provides a month of plant and lawn watering.
  • Native plants requiring less water are established, with an emphasis on those especially suited for the local climate and the House’s particular site.
  • Reduction of turf grass area means a reduction in lawn maintenance needs.
  • Behind the house a permaculture microclimate and intensive garden allow the homeowners to grow and enjoy their own fruits and vegetables.
  • Hardscapes are paved with permeable materials to reduce run-off into storm sewers and waterways.

Kenilworth Bungalow – LEED Platinum


A new home along the Kenilworth Lagoon – reminiscent of a modest Arts and Crafts bungalow – is scaled to fit the specific needs of the homeowner and tailored to match the scale and character of the neighborhood. Designed by Domain Architecture & Design®, Minneapolis, MN, the interior of this single-family, detached bungalow feels large and spacious, despite it small footprint. This LEED for Homes registered project also benefited from a whole-structure, whole-site, integrated design approach utilizing emerging, as well as proven, sustainable technologies and construction systems. Sustainable design strategies were integrated in ways that harmonize cutting-edge technologies with a traditional aesthetic.In September, the Project’s strengths were acknowledged through its selection to the prestigious ’09 AIA-MN Homes By Architects Tour. A distinguishing feature of the home is its construction from structural insulated panels (SIPs). These panels, which were custom built off-site, sandwich insulation between a structural skin of two sheets of OSB

(oriented strand board) structural skin. This eliminates on-site waste common with typical wood framing, increases construction efficiency, and creates a high performance building that is stronger, quieter and considerably more energy efficient than homes of traditional construction. The use of SIPs, as well as high-efficiency windows, appliances, fixtures, and heating and air conditioning systems, will drastically reduce energy use and energy bills. In fact, with a HERS Index of 49, this home is projected to be 51% more energy efficient than its built-to-code-standard analogue would be. Moreover, the indoor air quality of the home should far exceed that of a conventional home, thanks to the use of low-VOC paints, formaldehyde-free cabinetry, and integrated moisture control measures that will limit mold and mildew build-up. The landscape design retains and infiltrates 100% of an ‘average’ rainfall onsite, allowing the owner to defray costs via municipal stormwater abatement credits and minimizing use of the site’s high efficiency irrigation system. This is the result of utilizing only no-mow turf; non-invasive, drought-tolerant,native flora; numerous infiltration devices; and pervious-concrete ‘trapping’ strategies in the driveway.For every square foot of impervious concrete hardscape found within the site, there is a square foot of
pervious (permeable) concrete offsetting it. Domain is committed to green building, with designers that are LEED accredited, and completed projects that have been recognized for excellence in sustainable design – such as the renovation of the Pillsbury Library in Northeast Minneapolis (LEED-NC v2.2 Gold).

 The plumbing system utilizes a central-manifold plumbing system to conserve water and to equalize pressure throughout system.  Plumbing fixtures (lavatories, showerheads, and toilets) are all high efficiency fixtures.  A heat recovery system provides continuous ventilation of fresh exterior air into the home.  Individual forced-air registers are pneumatically controlled from the furnace room to balance airflow throughout the home.  The fireplace and energy efficient furnace are direct-vented, and the energy savingr water heater is power-vented.  Landscaping includes three rain gardens, drought resistant flora, and no-mow turf.  The driveway’s outer concrete bands slope inward, directing water to the permeable center section, with a crushed rock field below. Water then percolates into the lower rain garden.  The irrigation system includes a zone controller, drip irrigation, and a rain delay controller.

The Isabella MN Ecologically Balanced Building goes to the Wolf Ridge Environmental Learning Center

Imagine that every building maintained the ecological balance needed to sustain life on earth. Then, imagine all of humanity motivated to take action, to make this dream a reality. An immensely complicated goal? Maybe. But if we put our fears of failure at the back of the bus, we will maximize the possibility of success.

An immensely complicated goal?  Maybe.  But if we put our fears of failure at the back of the bus, we will maximize the possibility of success.

Nature has provided us with many examples of “buildings” that achieve an ecological balance.  If we follow her example, it is indeed realistic to believe we can prevail.

An Ecologically Balanced Building (EBB), then, is the most advanced building possible for our times because it strives to replicate the ecological balance found in nature.

An EBB incorporates a multitude of interrelated, smart design choices, resulting in a building that virtually lives and breathes, is beautifully balanced, aesthetically pleasing, and is socially responsible and sustainable.  It must meet the following criteria:

1.       Generate more clean energy than it uses.

2.       Sustainably manage the use of water.

3.       Waste nothing.

4.       Adapt to new conditions.

5.       Work symbiotically with all other living things.

6.       Eliminate toxins and pollutants.

7.       Add beauty & justice to our world

We have the technology and the building science to achieve these lofty imperatives.  Fortunately, we are also able to monitor, measure, and verify claims that a building actually accomplishes its intended goals.  If we can’t prove our claims, they are meaningless.

The Isabella EBB Project’s initial goal was to create the most environmentally conscious building possible.  It targeted integrating all seven design criteria listed above.  Additionally, each criterion is monitored, measured and verified to prove, we can indeed live in balance with nature.  Following is a description of how the Isabella EBB Project integrated the design criteria:

1.        The Isabella EBB Project was designed to consume an annual energy load of 4.5 kBTU/sq-ft. It achieved Passive House Certification, (HERS rating of 3), as the design method to achieve this extremely low energy use index. This is similar to having a 200 MPG car in lieu of our standard a 25 MPG car. There are 9,700 Heating Degree Days in this climate zone & 189 Cooling Degree Days.  This was accomplished through the design and construction of thermally broken/R 55 walls and R 90 roof, the use of high performance windows with glazing selected specifically to optimize the solar gain for each orientation and an air tightness of .5 air changes per hour.  Using BTU meters on the heating distribution system, the system is to telling us if the design loads are being met.

2.       Because extreme measures were taken to reduce the energy loads for this building, renewable energy generation produces more energy than is needed to operate the building.  An 11,000 kWH per year PV system/8.4 kw peak load and 92 solar heat collecting vacuum tubes averaging 172,500 BTUs per day collect renewable energy. An experimental long term solar storage area using 16 inches of EPS  insulation on all six sides contains both waste taconite from mines and sand.  Excess solar heat collection in the summer, fall and spring are stored in this solar storage containment area under the building.  The monitoriong system is gathering temperatures of the containment area, the Kwh generated and used  and kBTUs for the collection system.  We hope to prove that we are producing more clean energy than we use and that this solar storage system can be scaled down for use in other buildings.

3. Two additional areas used for solar storage: a 500 gallon water tank and an 80 gallon domestic hot water tank.  These are also being monitor and measured to tell us how hot they are and how many days of cloudy conditions depletes the stored energy supply.

4. A small electric boiler is used for backup energy should the building need it due to depletion of solar energy.  This boiler is also being monitor to tell us if it is being powered on.  This has already proven to be a great diagnostic tool, as it told us that the relays and sensors were not properly sequenced because the boiler was turning on whenever the domestic hot water dropped a few degrees.

5. A Heat Recovery Ventilation System makes sure that the building and occupants are receiving the right amount of fresh air at the right temperature.  An innovative ground loop heat recovery system is connected to the HRV to preheat the outside air prior to being heated by the exhaust air from the building.  The success of preheating  the incoming sub zero temperature fresh air with heated water from the ground near the footings of the building is being gathered by the monitoring system.  We hope to discover a 10 to 15 degree preheating of temperature through this system.

6. A rain water collection system and vegetative roof assures that water continues to perform its job of replenishing the aquifers and supporting plants and animals that conversely support an ecologically balanced building.

7. Information being stored through the use of the monitoring system is allowing the building to be adapted to new conditions and future improvements. Security alarms, for example, are sent when power, pumps, temperatures or water levels are not performing as intended.  Historical data gives us the ability to adjust and improve the performance due to accessibility to baseline and historical data.

8. An extreme waste and material management system was incorporated in this EBB.  Sustainable & reclaimed wood products, fast growing bio-fiber products, repurposed materials (e.g., old doors for ceilings, old radiators fins for guard rails, old wine barrels for chairs, old chalk boards for sills, and reclaimed tile), contribute to achieving zero waste and low life cycle assessment values.

9. Two highly recognized environmental third party auditing/certifications (LEED and Passive House) were achieved for this project, certifying the project at it the highest level possible.  This achievement summarizes that there were many other features, to lengthy to describe for this entry, that make this project one of the most advanced ecologically balanced buildings of our times.

10. Social justice and beauty are parts of ecology that acknowledge the value of spiritually engaging people through art  while also supporting  the notion of providing equal access and opportunities to all people.  The Isabella EBB project embraced adding beauty through the creation of a place that is welcoming, educational, inspiring, healthful, intriguing and fun.  The importance of social justice was a goal that surfaced during the learning experiences of the project.  Consequently, the project will be willed to the Wolf Ridge Environmental Learning Center, as an extension of their educational mission of teaching and influencing students the importance of living in balance with nature.

Isabella EBB Project Team

The critical success factors for the project team included:

1.    keeping the integrated design process alive and well throughout the entire projects development,

2.    checking  boiler plate designs at the door,

3.    if the project team achieved the goals stated above the points would follow and certification would provide the auditing needed to further validate our assumptions.

3.    understanding that everyone was on a ecological educational journey

4.    that fearless, open and honest communication  was mandatory, (typical passive/aggressive northern climate personality styles would keep innovation from reaching its potential).
