The MN Brick House project goes GreenStar Gold and scores 10!

This 123 year old house was renovated to high-performance with green features, with the goal of achieving a near-zero carbon footprint for the property within the parameters of an affordable housing budget. This project is the prototype for the nonprofit Carbon Zero Home, whose mission is to promote a zero net carbon movement, with an emphasis on built-world projects in rising communities. Carbon Zero Home’s goal is to locate the most affordable means to achieve a renovation that is carbon neutral.

Tell us what is unique or innovative about this project
The house was built in 1894 with only a crawl space basement. Somewhere around 1958-60 (per homeowner recollection), the house was jacked up and a full basement was dug underneath, with steel beams and posts installed to support the center bearing. Without this newer foundation, the house would not have been worth saving. The exterior brick was preserved and tuck-pointed, as were the original hardwood floors. The house was originally for the sleeping quarters for the farmhands, and had no kitchen when first constructed (or bathroom, for that matter). As a result, the center room on the first floor became the kitchen, and for a house this old, it has a remarkably large and functional kitchen.Because the stairs were way too steep, we had to rebuild the stairway. Because of the brick exterior, we could not relocate or resize any windows. This forced us to float the new stairway away from the exterior wall. Building on this feature, we created an open stairway in an open concept main space, which gives the interior a very modern vibe. The house became an eclectic mix of old and new, which gives it a unique look and feel.

Give us success stories as well as lessons learned

Success: the house performs quite well, given its age and the limited budget available.

Lessons learned: 1) For some aspects of the project, hiring the work done instead of self-installing would have saved money, by saving time. 2) Volunteer help often translates into more work, not less, because of all the effort involved in organizing the volunteer group– insuring enough tools and materials are on-site, creating enough activity to keep 25 people busy for 7 work hours, providing coffee and bagels, lunch, etc., and the effort involved in cleaning up after the volunteers have ended their day.

Any special thermal envelop, insulation or passive heating & cooling details?
The attic ceilings were covered with 1″ rigid insulation, then furred out with 2×2’s, then sprayed with closed-cell spray foam. Above the foam, we added 16″ of cellulose insulation.The walls studs were furred out with 1″ rigid foam, then 1×2’s were added over the insulation. The wall cavities were sprayed with 5″ of closed cell foam, which created a continuous envelope and addressed thermal transference.

We did not insulate the foundation walls. Instead, we install 2″ of rigid foam on the basement ceiling. In the middle of the basement, we built a mechanical room/laundry room. We installed 1″ of rigid foam on the outside of the mechanical room walls, then filled the cavities with batt insulation. We weather-stripped the laundry room door, as well as the door at the top of the basement stairs.

Any special HVAC systems worth mentioning? Describe them
We connected an HRV to the 97% efficient variable speed 60,000 BTU furnace. Using the furnace ducting for the ventilation system saved us considerable money.
Explain your water conversation strategies
We built a rain garden in the back yard, and we terraced the front yard to collect as much rainwater as we could. It is a long narrow lot that is well sloped to the front. Historic water infiltration caused us to slope concrete along the east side of the house to maximize diversion from the foundation. While we minimized concrete use for the garage by reducing the garage size to single car and installing gravel in the carport area, we felt that heavily pitched concrete was necessary along the house, given how much water travels through that area in a heavy rain.
Tell us about your place or location strategies
This home is part of EcoVillage in North Minneapolis, a struggling community that has been greatly revitalized through the efforts of Project for Pride in Living and Habitat for Humanity.

A ventilation system that monitors the air for toxins when they are present?

Build it tight, ventilate it right is now the mantra of the green building industry. With codes, programs and just general awareness new and existing home renovations are making homes tighter and saving energy. Because of these, things like ventilation are made mandatory and necessary to maintain health. Studies showing supply or exhaust ventilation only may not be healthiest and that even general balanced systems can waste energy for the trade off of the importance of fresh air. Cue the growth of Energy or Heat Recovery Ventilator, a system that acts as the lungs in the places we live but also captures 75% to 95 +% of the lost heat energy. These systems are good at saving energy and ensuring health but can over ventilate when not needed or not exhaust enough pollutants when they are introduced to the house!
The solution? 

Build Equinox manufactures the CERV (pronounced “serve”) smart ventilation system. On-board CO2 and VOC sensors combined with heat pump energy recovery make the CERV the most capable air quality management system for high-performance homes. Real-time monitoring of the home’s air quality along with temperature and humidity give control and peace of mind to homeowners that their house is being kept healthy and comfortable. Designed and built in the United States, the CERV is UL Listed and assembled in a 100% solar powered facility located in Urbana, Illinois. Live Healthier, Live Longer. Live Better with a CERV.cerv

The CERV is a fresh air ventilator for residences that automatically maintains excellent indoor air quality by active control of carbon dioxide and Volatile Organic Compounds (VOCs). A heat pump is used to exchange energy between fresh air and exhaust air streams when energy exchange is beneficial. Online monitoring capability, local exhaust boost mode, Geo-Boost heat exchanger, and zone dampers (multi-family) are some of the CERV’s options.

LEED is changing. Are you ready?

So here we are, October 2016.

Those of us in the green building world know this is a big month.

The universe’s largest green building certification program is about to do an upgrade. You knew it was coming for a long time, similar to a Windows upgrade; you know you need to do it, but you just have been so busy and pushing the “upgrade later” button. In 2014 you collectively pushed it for the last time and instead opted for a small upgrade that didn’t require a restart. But now, here we are in 2016 and the upgrade is coming and it has to come and so you might be scrambling the last min to make the preparations and make sure you are ready even though you don’t feel like you are!

The construction market is back up; green building is trending as a 80 billion dollar industry (soon), and now there is 400 ppm of CO2 in the atmosphere with no end in sight. Asthma and poor indoor air quality are on the rise and some cities Like Grand Rapids, MI where I am from, construction waste is reported to make up the largest portion of landfill waste.

LEED cannot solve all our environmental problems but can serve as a guide and standard when the time to act is now. Buildings and homes account for a majority of energy sources; their location can influence driving, and they have a big impact on our health.

The new version of LEED is going to be more difficult in many ways, more energy efficiency requirements (especially for rural or less connected projects), more thought will need to go into where you source materials from, where they are going at the end of their life and if your no VOC paint is certified to be so. For multifamily buildings we need to make sure apt units are communicating less to ensure occupant health and comfort, water pressure is being tested to reduce leaks and ensure flow rates work.

These changes are different, but they are good. The good news is for Homes projects; you will see a reduction in paperwork, no more chasing subs for signatures, no more durability plans required as it is all done in energy stare and just 1 signed workbook plus a few photos and energy reports. Another bonus is water performance calculations that allow the client to decide what is more important to them, similar to energy modeling and reduce in those areas (outside, kitchen etc)

If you aren’t ready yet that is ok, we are here to help you clear off your desktop before the upgrade restarts you construction process on 10/31.

Submit your project inquiry now, and we can help you get registered asap under v2008/2009. You won’t have to pay for 90 days, giving you time to secure funds or back out in Mid January if you cannot. No commitment.

Ready to take the plunge?

On November 2nd we are hosting 2 back to two back free CEU (APH) webinars on this topic.

The first webinar is a basic understanding of LEED for Homes and how it works(updated for V4) and the 2nd session 30 minutes after is a comparison on the differences of V2008 VS V4 for homes Home, multifamily and Mid to high rise mixed use buildings.

Sign up now as space is limited!

Finally, if you want to get the full education, check out our recently launched understanding LEED for Homes V4 on demand series where we take a deep dive in each of the categories (energy, EQ etc) and compare the differences of 2008 vs. v4

Thank you for your commitment in marking homes healthier and more sustainable!

GreenStar Homes Certification program update August 2016

Here is a summary of this month’s minor improvements to the GreenStar workbook with full details below.
  1. New link to access the checklist is here
  2. Pre-occupancy flush prereq was updated
  3. Landscape credits for mulch and fire safe areas were fixed and points were added
  4. Pre-construction design strategies 2.4.2 Air Changer Per hour was updated and health points added.
  5. Credits removed for documenting energy use devices and carbon footprint.

1. Finish & Materials coatings section 9.1.1 has been updated to be more tolerant when it comes to pre-occupancy flushing. Now it is 48 hours non-consecutive and allows to use windows and not just HVAC.

2. Pre-construction design strategies 2.4.2 Air Changer Per hour was very outdated, and health points have been added at 3 ACH or under. We also removed the 2.4.1 ACH @ Natural since it was redundant but if that caused a significant disruption to your project, please register by the end of the month and we will maintain those credits for you.

3. 2.2.4 & 2.2.5 Document all existing conditions, equipment and assemblies in the house & Estimate carbon emissions of operating the home have been removed now because they are a standard part of home energy models, labels, and scores.

Leff Project – LEED Platinum Single Family

Strategies and Results
The existing home foundation was reused, and advanced framing techniques and building envelope upgrades were used to improve energy efficiency and reduce construction waste. Superior walls with spray foam were used in the crawl space foundation of the new addition. BioPCM phase change material was used in west facing walls and ceiling deck under solar shingles. A spray foam/rock wool combination was used in other areas in the home. The south-facing roof incorporates DOW POWERHOUSE™ solar shingles to generate building-integrated renewable energy. Earth tubes were installed to temper incoming air.

Exemplary Performance
Ultra high-efficiency bathroom fixtures, including a wall-mounted Duravit toilet in master bath, were used to maximize water efficiency. Drought tolerant natural landscaping was used to reduce irrigation water demand by an estimated 62%. Aging-in-place design strategies were incorporated to ensure owners could stay in the home regardless of mobility issues that may arise in the future. Plumbing for future grey water management was installed as local building codes allow. Energy and solar modeling performed to bring project as close to net-zero energy use as possible.

Kenyon College Ohio – LEED for Homes Gold Townhouses

The new North Campus Housing project at Kenyon College, furthering the College’s commitment to green practices in all new building construction, is expected to win “LEED for Homes” gold certification. The award is based on a nationally recognized rating system that encourages the design and construction of high-performance homes promoting both human and environmental health.NorthCampusHousing13630101316

LEED, or Leadership in Energy and Environmental Design, is a program of the U.S. Green Building Council. Under LEED programs, projects can win certification based on an array of environmentally friendly features and practices. The rating system, developed by consensus among experts, includes four levels: certified, silver, gold, and platinum.

Designed by Gund Partnership of Cambridge, Massachusetts, and built by Messer Construction of Columbus, the Kenyon project will ultimately create a village of 21 townhouse apartments clustered around a common green space in the northern part of campus. The first four buildings opened for students in August 2011 and an additional two buildings opened for the spring 2012 semester. When phase two is completed, the apartments will house 220 students.

Third-party verification, an essential part of the LEED for Homes rating system, provides a basis for quantifying the benefits of green homes. Sol Design and Consulting of Cincinnati is serving as the project’s green rater and has been involved with the project since its inception. To ensure proper performance, each home undergoes onsite inspections and thorough performance testing after completion.

LEED measures a home’s performance based on eight categories: site selection, water efficiency, materials and resources, energy and atmosphere, indoor environmental quality, location and linkages, awareness and education, and innovation. Key elements contributing to the housing’s anticipated gold certification include the use of high-efficiency building systems and plumbing fixtures, geothermal heat exchange for heating and cooling the homes, and the use of Energy Star appliances.

The buildings’ design minimizes energy consumption caused by uncontrolled air leakage into and out of air-conditioned spaces. A blower door test on the completed buildings resulted in Home Energy Rating Standard (HERS) scores of 61-65, indicating that the buildings are 35-39 percent more efficient than a standard home built to code. Kenyon plans to display all utility information on Web “dashboard.”

LEED for Homes also requires a “durability risk planning process and evaluation” that promotes the durability and high performance of the building envelope and related components. To meet this requirement, Kenyon used materials, paints, sealants, and carpeting that are low in volatile organic compounds-features that help protect the health and promote the comfort of occupants. Landscape elements include a drought-resistant lawn, non-invasive species in plantings, a reforestation mix on lands greater than 1:4 in slope, and swales with plantings that help with surface water management. In addition, more than 83 percent of the construction waste thus far has been recycled rather than sent NorthCampusHousing13630101205to landfills.

The apartments have been very well received by residents. The twelve-student houses contain three to six bedrooms; each unit also has a living room, kitchenette, and dining area. Spaciousness, ample natural light, and a balance of common and personal space were among the most popular features cited by residents.

This housing initiative will allow Kenyon to relieve overcrowding in its residence halls. Upon completion, the additional capacity will enable the College to refurbish and modernize existing residences. The project will also help Kenyon realize its long-term goal of improving student housing and will give it a competitive advantage in recruiting students.

About the USGBC and LEED:

The U.S. Green Building Council is a nonprofit organization dedicated to sustainable building design and construction and the developer of the Leadership in Energy and Environmental Design (LEED) building rating system. LEED is a registered trademark of the U.S. Green Building Council.

About Gund Partnership:

Gund Partnership is a nationally recognized architecture and planning firm based in Cambridge, Massachusetts. The firm has completed several award-winning projects at Kenyon College, including the Kenyon Athletic Center, Peirce Hall expansion and renovation, and, most recently, the Gund Gallery.

Energy efficiency and other environmentally friendly aspects of Kenyon’s new student apartments should bring recognition from the U.S. Green Building Council.

Green Features:

• Geothermal heating and cooling

• Energy Star appliances

• High-efficiency plumbing fixtures

• Materials low in volatile organic compounds

• Environmentally friendly landscaping

• 83 percent of construction waste recycled
