Northbrook’s First LEED Home – Permit Rebate

This article republished from patch.com

As the first planned green home in Northbrook, the 4,500-square-foot, 2-story, 4-bedroom house will take advantage of the land’s orientation and unique flood, solar, and energy conservation characteristics. The home’s owner and general contractor is Ihab Riad, owner of Green Park Construction, a builder of luxury custom homes. As the first LEED-certified home in Northbrook, Mr. Riad expects to receive a rebate for the building permit fee, given Northbrook’s green building incentive program.

Riad, who currently lives in Mt. Prospect, hopes to showcase what can be accomplished with sustainable design and construction through this project, he and his family’s new home. Green Park Construction has already submitted design drawings for a preliminary LEED rating for the project. The LEED system gives credits for several different “green” metrics of a building, including energy savings, water efficiency, CO2 emissions reduction, recycled content, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts. Riad said initial estimates put his home at a LEED-Silver rating, and if he achieves some disputed points it could even achieve LEED-Gold, the second-highest rating the USGBC bestows, just below the net-zero energy rating of LEED-Platinum.

“We won’t be surprised if it scores higher (than silver),” Riad said. “We have a lot of innovation points from some of the systems we’ll be using, such as geothermal heating, but the goal is not to do these things just to get LEED points, we’re doing it because it’s the right thing to do.”

Riad was born in Egypt and moved to Mississauga, ?Canada, at the age of 16. Growing up in our neighbor to the north instilled a lifelong belief in environmentalism and green architecture, he said, a focus that is interwoven with his career in real estate and construction. The home was designed by Mark Rupsis, principal of Rupsis Associates in Shorewood.

“We embraced new ideas in the design stage,” Rupsis said. “Using geothermal, structural insulated panels and some of these other technologies are much different than conventional design, but actually quite easy once you know how all the pieces fit together.”

Structural insulated panels, or SIPs, are a composite building material. They consist of an insulating layer of rigid polymer foam sandwiched between two layers of structural board. The rigid insulation core of the SIP acts as a web, while the outer sheathing insulates. SIPs are unique because they combine several components of conventional building?such as studs and joists, insulation, vapor barrier and air barrier—into one material. They can be used for many different applications but are mainly being applied as a continuous air and vapor barrier on Riad’s house. All of the exterior walls will be SIPs or precast concrete panels. This continuous air barrier is designed to keep the cold out and keep heat pumped up from deep underground via the house’s geothermal heat pumps, in. The plans also call for highly insulating Anderson 400 series windows, bamboo flooring throughout and a Superior Walls foundation made of precast concrete. This will be the first home project in the Midwest where SIP walls were used with a Superior Walls foundation.

Riad is taking advantage of construction efficiencies made possible by these technologies. All of the SIP walls and precast pieces will be built in a factory and delivered to the site ready for installation.

“The first floor walls take two days to put up,” Riad said. “The second floor walls will be in up in a month. We’re expecting one to two days for the installation of the foundation, as well.”

By using these delivery methods Riad can take advantage of construction waste reduction credits available in the LEED system as well as innovation credits that could contribute to a LEED-Gold rating. Riad expects the roof and all of the walls to be installed and completed by January and the home ready to live in by August 2011.

Riad had nothing but good things to say about working with the Village of Northbrook’s Planning Department to approve his unconventional home.

“Our staff had to do research on these emerging technologies to make sure they were compliant with codes,” said Tom Poupard, director of planning and development services for the Village. “Most of our codes include performance-based standards, so as long as we can get documentation that a new approach meets or exceeds our requirements and does not cause  some other problem, such as flammability, it is going to be fine.”

Poupard said the primary way in which the Village encourages green construction is by means of its LEED building program, wherein building permit fees are rebated to the homeowner after a home is certified by the USGBC. Since this is the first residential permit approved, Riad will receive a 100 percent rebate of the fees upon certification.

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. 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).

Durability Planning and Prerequisites in LEED Homes

Those familiar with the LEED for Homes rating system know there are many prerequisites that all projects must meet prior to Certification. These are spread across the credit areas, so there are prerequisites in Indoor Environmental Quality, Energy, Materials and Resources, and more.

One area that is a bit confusing is the Innovation and Design prerequisite for Durability Planning and Management (ID  prereq 2). This is a two-step process to help ensure homes are durable and built to last by mitigating any local climate variables on the home.  The first step is to identify risks, and the second is to identify strategies to address those risks. For example, if the home is being built in an area with high air infiltration, heat loss, and water infiltration, what design and construction strategies are being used to mitigate these issues?

Flooding impacts a building's durability

Often times, these durability strategies are common to local building practices and are already being planned by the project team (e.g. attention to window flashing details, moisture management, etc), but in a LEED  home, the project team is taking these strategies and mapping them to specific risks.  With this kind of attention and the third-party verification most LEED homes pursue (ID 2.3), you can see why home insurance companies are willing to give premium discounts for LEED-certified homes.

There are also design and construction practices that affect the durability of the home and potential health of the homeowners inside the home, particularly related to moisture management. As such, the LEED for Homes checklist has several durability strategies that are pre-filled for the project team. These are basically hidden prerequisites in the rating system within ID 2.1. Some examples include:

  • Carpet is not allowed within 3-feet of an egress door.
  • HVAC distribution system must be fully ducted (no wall or floor cavities can be used as ducts).
  • Paperless drywall required around tubs/showers (not “green board” drywall).
  • Washers in or above finished spaces must be on drain basins or have a “single-throw” laundry valve accessible to the occupant.

Many of these items are common sense practices that quality builders have been doing for years. Nevertheless, all LEED homes must meet these specifications.  They can be found on the “Durability Inspection” tab of the LEED for Homes checklist.

While talking generally about Prerequisites in LEED for Homes, I’d be remiss if I didn’t mention some of the common ones that may be easy for project teams to miss:

  • Carbon monoxide detectors required in each unit on every level. (IEQ 2.1)
  • In split-system air conditioners the refrigerant charge must be weighed in the field. (EA 11.1)
  • Kitchen range hoods must be ducted to the outdoors. (IEQ 5.1)
  • Bathroom exhaust fans must be Energy Star rated and ducted to the outdoors. (IEQ 5.1)
  • Manual J & D calculations (or equivalent) must be done room x room for duct sizing. (IEQ 6.1)
  • Any fireplaces and woodstoves must have doors (IEQ 2.1)
  • Site erosion controls must be in place during construction (SS 1.1)

The list above is just a partial list – there are more prerequisites in the LEED for Homes rating system. This is just a sample of some that we have seen project teams question or miss.

As you can see, the project team needs to put a lot of thought into the design of the homes to help ensure every LEED-certified home is durable and built to last for many, many years.

The Vineyard Project

Nestled in South Western Michigan’s wine country this home is located next to a vineyard in Paw Paw, Michigan, thus the project name. This home is a site specific, Passive Solar Prairie style home built with BuildBlock ICF (Insulated Concrete Forms) from foundation to the roof. The exterior elevations of the home were designed with deeper roof overhangs, determined by using solar calculations, to both maximize and minimize the sun exposure based on the time of year. In addition, solar awnings on the lower level windows further shade the South-facing windows. The exterior used two of our favorite products CertainTeed FiberCement Siding and Andersen 400 series casement and awning windows. The interior of the home has stained concrete floor on all levels which makes for great thermal mass. The home was also designed with lifetime design principles and has zero step entries. Click here to view the project profile

art of the site specific design was to locate the garage to act as a wind break, to stop snow drifting from the northwest prevailing winds that we have here in Michigan. Part of the passive solar design is to have very little windows on the north side of the home, to keep heat from escaping through them. That is why this homes attention to detail is spent on the Southside of the home, where most of the homes windows face south. In the winter, the sun will warm the living space during the day and shine on the concrete floors on both levels which will store some of the heat gained, for gradual release. The roof overhang will shade the house from excessive solar heat gain in the summer, and west-facing glass is minimized to reduce cooling needs in the summer. ICF construction was perfect for this project because with ICF’s there are no concerns with noise and wind.

The “Vineyard Project” is a Zero Energy Home (ZEH) thanks to the Passive Solar Design, 3.3 kW of Photovoltaic, Solar Hot Water and the Geo-Thermal heating and cooling system. The home is also pre-wired for future installation of a Wind Generator. This home only uses about 600 kWh of electricity per month and has been generating a minimum of 20 kWh of electricity per day with many days’ net-metering backwards since the home was completed. The home was built for $134.00 per square foot (before the 30% rebates from the Solar Hot Water, Photovoltaic and Geo-thermal systems) making it more affordable for the general public.

Besides the pending LEED for Homes “Platinum” certification this home received 5+ Energy Star certification and a HERS score of 34. This is the lowest score every tested in the State of Michigan making it the most energy efficient house in Michigan. This home will be 66% more efficient than typical construction of a similar home of this size. In addition this homes toilets, faucets and shower heads are super low-flow for superior water efficiency. The home also has low-VOC paints, adhesives and finishes and uses recycled content for the flooring, decking, foundation and siding.
