Central Michigan University Completes LEED Platinum Dorm

CMU PIC 2

“This $28.5M project involved the construction of two new student housing buildings for Central Michigan University’s (CMU) graduate school. Hoping to emulate apartment living to attract the students who might otherwise choose to
live off-campus, each unit includes private bathrooms, kitchens and laundry facilities—with a mix of one, two and four bedroom units throughout the two structures, with 164 beds total between the two buildings.
The buildings were designed to emulate the Gothic architecture present on campus and the design and construction teams ensured that LEED sustainable features incorporated into the design were properly integrated. Large windows
were added to provide occupants with daylight in regularly occupied areas. A campus-wide green housekeeping program was implemented. Regionally manufactured materials containing recycled content were used extensively throughout the project. Equipment was selected to ensure that refrigerants would cause minimal damage to the atmosphere. Additionally, all HVAC and electrical systems were commissioned and certified that they were installed per specification and working as designed. The design also limits disruption of natural hydrology and all but eliminated pollution and contaminants from stormwater run-off. Universal design practices and sustainable design measures were integrated into the design to create an energy efficient complex recognized by its tenants as a great place to live and by the community as a model for sustainable living, earning the coveted LEED for Homes Platinum Certification.

SUSTAINABLE HIGHLIGHTS

CMU PIC interiorSUSTAINABLE SITE
The pedestrian scale buildings support CMU’s and the City of Mount Pleasant’s mutual goal of a walkable community. The new Graduate Housing units are located on the north end of campus on Bellows Street, just steps from the Health Professions/College of Medicine building and close to Mission Street as well as downtown Mt. Pleasant.

WATER EFFICIENCY
The landscaping was designed to require 50% less irrigation, reducing the use of potable water. In addition, a 33% reduction in potable water and sewage usage was achieved by careful selection of water efficient plumbing fixtures, faucets, and flush valves.

ENERGY EFFICIENCY
The overall energy performance of a new building can not be measures until after the building has been built. Thus, the energy performance of a building must be predicted using energy analysis software. The Residential Energy Services Network has developed a set of guidelines for accessing the relative energy performance of these units. Commissioning of all HVAC, lighting and domestic water systems were conducted to ensure that all systems operate as designed. All equipment was selected to cause minimal damage to the atmosphere.

CMU LEED Label

 

MATERIALS AND RESOURCES
During construction, 94% of all construction waste was reclaimed and recycled. Sources for the building construction materials were evaluated, recycled content materials make use of materials that would otherwise be deposited within landfills. The use of local materials support the local economy and reduce the harmful impacts of long-distance transportation.

INDOOR ENVIRONMENTAL QUALITY

An indoor air quality (IAQ) plan was implemented and low-emitting materials were selected in order to reduce any adverse effects on the IAQ once the building was occupied. The HVAC system was designed to meet the minimum IAQ requirements. No smoking is permitted within 25 feet of any air intake louvers. Low VOC (volatile organic compound) materials such as paints, carpets, sealants, adhesives, and casework were employed in order to provide a healthy indoor environment. The HVAC system was designed to maintain temperatures and humidity in accordance with ASHRAE standard 55-2007.”

WI Platinum 2.5k Square foot Home averages $30 energy bills

Thanks to Jetson Green for sharing this awesome post! (Article written by Christine Walsh on Nov. 28, 2013)

Architect Virge Temme of Sturgeon Bay, Wisconsin recently received the LEED Platinum for Homes certification for a private residence she designed near Gills Rock. The home was built by Bay Lakes Builders, and the plans were based on the collaboration of all members of the construction and design team so as to ensure proper integration of all systems. The electric and fuel bills for this 2,600-square-foot house were less than $30 per month on average during its first year. This is only the seventh home in Wisconsin to receive the LEED Platinum certification.

The building process started with the excavation of the meadow where the house stands, while the top soil was stockpiled and used for final grading later. Once the foundation was complete, the foundation forms were stripped and the below-slab plumbing and electrical runs installed. The builders continued with laying thermal tarp to protect the home from freezing rains. This was followed by the installing of under-slab insulation. All the joints were staggered and sealed in this process to prevent air movement between layers. Furthermore, all the penetrations through insulation were foam sealed, which protects against cold seepage and potential Radon gasses.

The roof was then installed, using 16″ I-joists to reduce thermal transmission and to provide additional insulation depth. The I-joists were placed directly over the studs below and the framed walls with studs at 24″ on center to reduce redundant top plate, which also reduced the overall framing materials need. The rafters were then screwed and strapped to studs to provide additional protection from wind. All the intersections were then foam-sealed.

To provide a continuous envelope 3/8″ OSB was added to the under side of rafters. Double 2-4 plates were screwed below the rafters to provide an electrical chase, eliminating the need for roof penetrations. The builders also used ladder framing, which greatly reduced the amount of redundant materials at wall-to-wall connections. Double-wall construction also eliminated thermal bridging and provided space for additional insulation.

foamsealing

The house has insulation values of R-45 for walls, R-60 for the roof, and R-30 for ground insulation. Together with passive solar orientation and specially-coated windows to introduce solar warming, and which also feature overhangs to protect from summer over-heating, there is no need for a furnace or a boiler for space heating.

Other sustainable features of the home include:

– Sustainably-harvested framing materials
– Recycled/recyclable metal siding, roofing and insulation
– Drought-tolerant plants replanted around the home
– Rain gardens for roof runoff
– Only low- or no-VOC paints, adhesives and insulation were used to ensure better air quality
– Floors are made of concrete and sustainably harvested bamboo
– Only highly efficient appliances, lighting fixtures, and plumbing were installed
– The building process resulted in almost no construction waste

Glenn Retreat LEED Home has Innovative Blackwater Design Feature

The “Glenn Retreat” project exemplifies water use reduction both outdoor and indoor, with a 72% reduction in irrigation due in part by
photothe AdvanTex(R) Wastewater Treatment Systems manufactured by Orenco (R) that is a environmentally sustainable wastewater treatment technology that treats blackwater and greywater so well that the treated effluent can be re-used for subsurface irrigation (We achieved a additional LEED innovation point with this system). Along with Infiltrating Rain Gardens, Edible Forest Gardens, Extensive use of Native Drought Tolerant Plants and Eco Turf Grass on the outside and with low flow WaterSense certified toilet and fixture on the inside this project achieved almost every point under Water Efficiency in the LEED for Homes checklist. Our approach to handling waste water and storm water turned a negative attribute into a positive one; and created a drought tolerant and low maintenance landscape.

glenn label

The site’s soil composition has high clay content, and coupled with a high water table makes for a less desirable building site. Fill dirt and sand were added to the center of the site to elevate the house a few feet above grade. Drain tiles and French drains were installed around the house to channel water into swales and rain gardens which we developed along the north, east and west property lines. This watering system has proven sufficient to support the wide variety of plant life added to the property. Our system eliminated the painstaking task of cleaning rain gutters too because we didn’t need to install any. The high water table also presented a challenge for the septic system. We selected an advanced system  that uses a smaller drain field, and generates effluent certified by NSF International for subsurface irrigation. A native wildflower and prairie grass landscape is being developed on the septic drain field.

Michigan's First Registered New Living Building & LEED Home – Burh Becc @ Beacon Springs

sketch of house on land

Beacon Springs: The Vision

Beacon Springs (Near Ann Arbor) offers hope for life springing from a sustainable dwelling, polyculture gardens amid oak savannah, and a lively gathering place. It is a beacon of hope for a happy, healthy and sustainable future for all.

Sustainable dwelling

Our house at Beacon Springs is named Burh Becc, meaning, in Old English, a dwelling by a creek. This is the origin of our family name Burbeck. Several natural springs on the north edge of the land feed a small creek which runs past the house. Wildlife is drawn to this source of water and vegetation, as were we when we first came to the site. Burh Becc has been designed as a “living building” using the Living Building Challenge standards of the International Living Future Institute (visit living-future.org). A living building becomes an alive component in a sustainable ecosystem, integrated with the natural environment in a way that nurtures and sustains that environment. It is because of this living nature of our house that we have given it a name, and we have designed and built it to serve many future generations.

Water. Our living building uses the rain and snow falling on the roof as its only source of water.

Energy. Burh Becc depends on the rays of the sun for most of its energy needs. Heat is provided mainly through passive solar design. Natural ventilation is provided by the wind drawn through the house by the tower design. Heating and cooling are augmented as needed by a photovoltaic-powered geothermal system.

Waste. Our house is designed to reduce waste products that need to be removed from the site and eliminate materials toxic to human or environmental health. 95% of the by-products normally considered waste are integrated back into the site ecosystem, or are recycled, repurposed or reused by the broader community. A 95% materials efficiency standard was also followed during the construction phase of Burh Becc, leaving only 5% for the local landfill.

Farm amid oak savannah

The farm at Beacon Springs produces food for the local community, particularly those with limited access to fresh produce, as well as for our own table. As with the house, the farm has become an integral part of the ecosystem. Following the principles of permaculture, plants, trees and animals work together for abundant and sustainable production of food. These permaculture methods also restore the fields depleted through decades of “factory farming,” they allow the garden farm to fit together with the rejuvenating oak savannah, and they encourage wise management of water for the benefit of the immediate site and neighboring ecosystems.

Gathering place

Our home has become a wonder-filled gathering place for people (and pets, too). The embrace of Beacon Springs – the living building, with its flourishing courtyard and barnyard animals, combined with the surrounding acres of permaculture gardens and oak savannah – is a balm to the lone poet and a catalyst for lively exchange in larger groups. Beacon Springs is a center of education for the community: architecture students learning about sustainable design; residential building crafts(wo)men and trades professionals learning sustainable construction methods; children learning about barnyard animals and bee-keeping; and permaculture enthusiasts participating in onsite workshops. Beacon Springs also provides a gathering spot for community farming. And we regularly welcome family, friends, co-workers and others to our table for good food and dynamic exchange of life.

A special note for our team of designers, engineers, builders and growers, and the extended team members through the International Living Future Institute: We hope that each of you, in joining the community responsible for the creation of Beacon Springs, has also received an extra measure of life springing from your contribution to the project. You are always welcome to come for a visit, enjoying with us the fruits of your labors.

—Tom and Marti Burbeck, Ann Arbor, Michigan, March 2023

West Michigan's first Energy Star Version 3 Certified Home

* correction – This is a new home and not a rehab.

The approach was a  LEED certified home that goes beyond most Habitat standards of just LEED silver and Energy Star Version 2.  The goal was to get a house to achieve the coveted Energy Star V. 3 certification and Indoor AirPlus certification by achieving higher standards for the HVAC.  The biggest hurdle for this house was installing a 95% efficient furnace coupled with an ERV mechanical ventilation system and flexible ducts in order to reduce energy costs and improve air quality throughout the 2-story house. The kitchen is outfitted with low VOC cabinets and a 100 CFM range hood which vents directly outside as opposed to in the attic or re-circulation.

The Indoor airPlus certification contributed largely to the Energy Star V3 Certifcation, as the higher quality HVAC system also covered many of the prerequisites. The biggest hurdle for this home was to find a credentialed HVAC installer who would work with the higher standards required for Indoor airPlus.   The water heater and furnace directly vent fumes outside and improve indoor air quality and efficiency of the equipment.  The HVAC also has LEED_TM_gold_13a MERV 10 rated filters and efficiently at 86 CFM, which fully circulates the air in the home approximately every 4 hours.  The furnace itself runs on a single speed PSC motor which runs at set intervals and uses the ERV to moderate the temperature.  The house also features a Superior Wall Foundation which contributes an R-Value of 5 to NuWool insulation installed on the walls for a total R-Value of 26.  To further increase the insulation of the house the rim joists were also insulated and earn an efficient .3 U-factor windows were installed to reduce air leakage.

The home appliances available in this house are Energy Star certified to accompany the Energy Star V3 certification on the house.  Outfitted with low formaldehyde pressed wood materials in flooring and cabinets, as well as low VOC paints and finishes on the cabinets and walls. .  Plumbing is outfitted using PEX piping as more flexible and reliable alternative to PVC or copper piping.

Habitat for Humanity Kent County is committed to 100% LEED Silver Construction and has saved homeowner’s $1,000 a year in utility costs as well as improved their indoor air quality compared to living situations they were previously in.

Metro Detroit's 1st LEED Platinum Gut Rehab Home

The Ferndale home is 45.6% more efficient in its energy use in comparison to an average 2,000 sq. ft. existing Michigan home.  The average is 3,948 kWh a month, while the Ferndale house used only 2,195 kWh. The overall cost for the electric use in the Ferndale residence is $74.56 a month, using 603 kWh, which is 34% less than the average, which costs $121 a month and uses 908 kWh. Heating for the Ferndale home uses 5.3 MCF and costs $23.85 a month, while the average uses 10.1 MCF and costs $127.46 a month. Altogether, the operation costs are 32% less than the average household to heat. 

*The project team attempted to get actual past utility bills to determine the success of the upgrades. However, they did not know who the previous homeowners were, and since, DTE and Consumers Energy have outdated privacy laws, they do not allow for the retrieval of data without homeowner permission.See full Ferndale Home Energy Report

The purpose of this project was to revitalize an abandoned home in disrepair, and through environmentally-friendly construction practices, to transform it into an energy-efficient home.  The house is 95 years old, had gone into foreclosure and had been vandalized while sitting empty, so it required a complete overhaul. Lee Purches, HP3 Group and project Green Rater helped ensure the quality and sustainability success of this home.   Lee connected the owner with Herzog Homes, which was willing to pursue LEED certification with some budgetary constraints. The goal of this project was to restore this old house, but also make it better through green building design and LEED certification.  The design team followed LEED protocol for local labor and materials, using renewable or sustainable products in aiming for Gold LEED certification.IMG_6158a

The result is an efficient, practical, and affordable home that is no longer an eyesore in an established neighborhood. This home is the first of its kind in metro Detroit, setting an example for others to invest in Green Homes and to restore existing homes rather than build new.    The home has been enlarged and now has a freestanding garage that also serves to capture water.  The house also has its own high-efficiency controlled irrigation system that evenly distributes water in the front and back yards.The backyard contains a 200 square foot vegetable garden, which includes fruit trees.  The garden benefits from the irrigation system and passive water collection to yield produce four to six months out of the year.  The indoor air quality 10 times better due to the ERV and high efficiency furnace.  The furnace is a two stage furnace that only runs at high capacity when necessary, and is 97% efficient.

The house is fully enclosed with open cell spray icynene insulation, from the basement wall all the way up through both floors to and the roof deck. The interior finishes, walls and trim contains almost no VOC other than the drywall glue and paint, which have low VOC ratings below 100.  New Jeld-Wen windows were also installed with a U-factor and solar heat gain of 31 for additional energy performance and reduced air leakage.

College of Saint Benedict Senior Housing, LEED Platinum Certified

The Centennial Commons townhouses were designed to be a sustainable part of the colleSustainability Photoge’s landscape. The 32 townhouses were intended to be at least LEED Silver certified. The townhouse were originally considered in order to provide affordable housing for the 90% of students that live on campus, particularly the seniors.  These townhouses were also built to represent the college’s commitment to sustainability, as well as the first college student housing in the state of Minnesota to have any LEED certification. Each townhouse has been outfitted with as many locally sourced materials, furniture, carpeting, and wood, as possible. The exterior is decorated with native plants and landscaping. Each townhouse is also individually metered for teaching students about their energy consumption and sustainability.

The 2-story townhouses were designed for a durable 100-year life and to be as efficient as possible.  The townhouses provide housing for 125 students, accommodating 3-4 students in 4 bedrooms, with 2 full bathrooms.  Each townhouse also has two bathrooms, laundry room, living room, kitchen and front porch.  Also included in this project was the Commons Building to provide the community with a gathering space, study rooms, computer lab, kitchen and a multi-purpose room.

The townhouses are clustered for a compact development within half a mile of community resources; churches, libraries, convenience stores, fitness centers and shops. The building site was selected as it was not a habitat for endangered or threatened species, a wetland or public parkland. The townhouses also utilize outdoor LED lighting, non-toxic pest control and low flow plumbing inside.  During construction 37% of waste was diverted, documented, and recycled while  erosion control was also put into action in designing and installing the landscape.

One unique feature, according to Judy Purman, CSB’s Director of Sustainability, is that each unit is individually metered for gas, electricity and water usage. Judy Purman also stated, “Each apartment will receive a ‘mock’ bill so that the residents will understand what their actual usage is,”  which in turn provides a “life skills learning opportunity. We’re integrating an educational component so that they will understand what it’s like to pay gas, water and electricity bills when they leave campus.”

It may be big but did you see the energy bills?

This home was cons015tructed with environmentally friendly materials and products.  The goal was to build a home that didn’t have a negative impact on the environment and would contribute to the home’s overall efficiency.

The result is beautiful home outfitted with natural bamboo hardwood floors, geothermal heating and cooling, superior insulation and Anderson Triple Pane Windows.   The house’s construction, due to its part being pre-fabricated offsite, diverted almost all waste from landfills.

The home  has greatly reduced utilities due to its design, costing $150 a  month or $1,700 a year due to temperature moderation, Energy Star certified ceiling fans in all rooms, water conserving (Water Sense) faucets,  and low flow 1.28GP toilets.

This home utilizes geothermal heating and cooling, which brings up 55 degree air from the earth’s crust, to effectively moderate the home’s temperature.  The house also has Structure insulated panels (SIP) installed for throughout the entire house, reducing the amount of onsite wastes and greatly increasing insulation.  The Kitchen, Foyer, and Great Room,  all have insulation with an R-value of 40, while all other rooms are at R24.  The attic, garage, and roof have an insulation of R40, but utilize spray foam insulation.

The Superior Wall Foundation was precast in Michigan with moisture resistant 5,000 psi concrete and placed on crushed stone footing to redirect water away from the foundation.  The foundation itself also includes R17 insulation to further reduce air leakage in the home.

Due the concrete foundation and sealing of cracks and joints in the foundation, the house has good protection against pests like termites.  The house also has a significantly reduced air leakage envelope, which is rated at 5.0 air changes per hour at 50 pascals (5.0 ACH50)   All ducts were installed in conditioned space, so there is no leakages withing duct work. The lawn consists of “No Mow Grass”  which does not require   fertilizer, mowing, or watering in its maintenance.

Matchbox House LEED Platinum Certified – Ann Arbor

The project started out with an intent to design LEED certified which is reflected in its unconventional design.  The project was modeled after a matchbox and was designed to have four inner quadrants that slip past on another withing the out sleeve of the house, all on top of

2216 Hickman Ann Arbor, Michigan

a raised foundation.   The Matchbox’s compact design contributed to it’s LEED Platinum certification as there was less conditioned area to work on. The architect gathered information from other contractors experienced in green building practices in order to produce a home outside the norm. The result was distinctive, efficient, and compact home surrounded by natural, permeable turf minimizing the impact of the house on the surrounding environment.

The house has four bedrooms, 1,738 sf of conditioned space and a one car garage. It has received LEED Platinum Certification. It has a HERS rating of 47 and many notable features, including FSC wood, reclaimed trim from demolished Michigan barns in the region, no conventional turf (no irrigation) and low flow plumbing fixtures. The house has no attic or basement so upstairs rooms have dramatic ceilings that begin at 3’-0” and end at 16’-0” with an angle ceiling matching that angle of the roof.

No conventional turf or irrigation system was installed around the home, and all fixtures and fittings (toilet, faucets, and showers) are very high efficiency, reducing the site’s water demand by 78%. The wood used in the cabinets, stairs, closets, doors, and upstairs floors are all FSC certified. The house itself is much more compact than a standard house, so much that the LEED threshold dropped by 10 points. The kitchen counter tops and decking are constructed are composite from recycled materials.

The home’s unconventional design earned it 1st Place in Detroit Home Magazine Design Awards 2013 for Contemporary House under 4,000 sq ft.

Preliminary Platinum LEED Rating
HERS Rating 40 (without PV)
Built to exceed Energy Star standards
21st Century Craftsman

“When we first started thinking about building our own home we knew we

wanted one that would be energy efficient, healthy and representative of our family. We appreciate the style and local history of Craftsman architecture, but also wanted modern touches like an open-concept floor plan, in‐home technology and environmentally friendly building techniques and products,” said future owners Aaron and Jenny Stash.

Enter Architect Michael Kollman and his company SmartHaus who will begin construction on the home in Northbrook this spring.  The custom, high-performance home is being designed and built to a LEED for Homes Platinum rating,

the highest rating given to homes when certified by the US Green Building Council. LEED homes are built to be energy efficient and environmentally responsible and are rated for health, comfort and durability by a rigorous third party review process.

SW Exterior View - Northbrook LEED

Why LEED for Homes?

“Why not?  The long term benefits of building an energy efficient, healthy home far outweigh the incremental upfront costs. Studies suggest the initial construction cost of a home represents only 11% of a building’s total cost of ownership. Beyond financials, the benefits to our family and our community are immense. If that weren’t enough, the Village of Northbrook’s forward-thinking  Green Building Initiative ordinance made the decision even easier.”

Homes that are LEED-certified measure a home’s performance based on eight categories: site selection, water efficiency, materials & resources, energy & atmosphere, indoor environmental quality, location & linkages, awareness & education, and innovation. A home that achieves LEED certification has been designed to maximize fresh air indoors, minimizing exposure to airborne toxins and pollutants, and in our case uses 45% less energy– than a home built to the International Energy Code Council’s (IECC) 2012 code in Illinois.

Economic, Social and Environmental Benefits

Less energy use means lower utility bills every month throughout the life of the house. Beyond energy efficiency, achieving LEED certification is a mark of leadership in green homebuilding, clearly differentiating a home as among the best in the country. LEED is like the nutrition label that demonstrates in measurable terms how a home incorporates efficient features, healthy indoor air quality and environmentally friendly construction practices with the added assurance that the final product has been third party-verified and performance tested.

“This is our future. The jump in technology and science over the last few years has been incredible.  We can accurately predict how a home will heat and cool and maintain healthy indoor environments utilizing very simple concepts and applications.  Homes can be fine tuned to take advantage of site features, owner’s preferences and budget. We can design and build homes today that can produce as much energy as they need to operate.  That goes for deep energy retrofits on existing homes as well.  There are financial incentives in place to help defray some of the costs of emerging technologies as well.”  Architect Michael Kollman says.

The house has been laid out to take maximum advantage of both passive and active solar energy, natural ventilation, low impact and recyclable materials, high efficiency lighting and controls, in a structure that is very simple and economical to build. “Every material and system has been studied in terms of its environmental impact and life cycle costs.”

The envelope of the house is designed to require a minimum amount of energy in order to live and use the home based on the lifestyle of the occupants.

The home will have an innovative HVAC system that has been recently developed by engineers from the University of Illinois which uses considerably less energy than a conventional heating and cooling system and provides extremely high indoor air quality utilizing a CERV (conditioned energy recovery ventilation system) combined with a cost effective installation.

The home has been reviewed by and has been given a preliminary Platinum rating, if you are interested in learning more about the SmartHaus, check it out at www.smarthaus.org
