College of Saint Benedict Senior Housing, LEED Platinum Certified

The Centennial Commons townhouses were designed to be a sustainable part of the college’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.”

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.

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.
