Whole Foods Mixed Use Market Rate Housing Certify LEED Silver in Minneapolis
Ryan Companies and The Excelsior Group collaborated to bring this 579,706-square-foot mixed-use project to downtown Minneapolis. The project – called 222 Hennepin – will contain 286 luxury apartments and will be anchored by the first Whole Foods Market in downtown Minneapolis.
Ryan Companies co-developed the project with The Excelsior Group, specialists in multifamily real estate. Ryan is also the architect-of-record and builder for the project, which will occupy a full city block at the corner of Hennepin and Washington Avenues. The corner is one of the most prominent downtown, and development challenges had kept it vacant for more than five years.
A 40,000 -square-foot Whole Foods Market occupies the ground floor of the project. Luxury apartments, featuring dramatic views of the downtown skyline and Mississippi River, occupy the second through sixth floors. Ryan Design worked with Humphreys & Partners Architects on the conceptual design of the project, which focused on balancing the housing needs of sophisticated, discerning apartment residents with the commercial needs of a top-tier urban grocery store.
Project amenities include a fourth-floor terrace with an outdoor pool, bocce ball area, fire pit, dog walk, enclosed party room, cyber cafe and state-of-the-art fitness center. The terrace itself affords spectacular views of the downtown Minneapolis skyline. The construction of the project prioritizes sustainable building practices by incorporating an existing 300-stall parking structure, effectively wrapping the new project around the existing improvements and re-using them.
In working toward LEED Silver Certification for mid-rise residential, the team
incorporated a variety of sustainable and energy-saving elements into the new building. Some of these features include:
- The downtown location encourages the use of public transportation as well as bike and foot traffic, which reduces emissions. In addition, the compact, amenity-rich site promotes community living.
- The existing 300-stall parking structure remained in place, which saved in excess of 20 million pounds of concrete and over 1 million pounds of steel rebar that would have been used to replace it.
- Saving the existing parking structure drastically reduced the demolition waste that would have been generated.
- Cleaning up, reinvesting and redeveloping an urban brownfield site of contaminates protects the environment and reduces blight.
- The building is 100% smoke-free and extra measures have been taken to seal the units to reduce air leakage which will lower the risks of indoor air pollutants.
- The use of high efficiency water faucets, showers and toilets reduce water demand.
- The off-site fabrication of the interior roof, walls and floors minimized the waste created on-site. In addition, approximately 65% of the construction waste was diverted from landfills through recycling programs.
- The use of low maintenance, non-invasive native plants, which will thrive in an urban environment, will reduce irrigation needs.

Michigan GreenStar’s First Certified Remodel in Grand Rapids
Being the Executive Director at an organization that promotes and trains on residential green building, Brett Little decided to put his money where his mouth was and commit to green remodeling in his first home purchase. Brett and his wife Laura wanted to commit to the up and coming city of Grand Rapids Michigan, which was easy to do with all the past few years of recognition and grow (Most sustainable mid-sized city, beer city USA 12′ and 13′, top ten place to find a job, most LEED building per capital and etc etc. ). The project is a prime of example of how one can use GreenStar on a small remodel / weatherization job without being too invasive to the home. 
The 2 story house circa the 1920s was aesthetically in great shape, had a newly remodeled kitchen, intact wood windows and trim, good paint, half finished the basement and very well kept landscaped (turf) yard.
What the house was missing was quickly shown in the inspection and energy audit. They revealed a lack of any decent insulation/air sealing, chuck full of incandescent light bulbs, inefficient water fixtures, noisy bath fan old and oversized heating/cooling systems along with a dinosaur of a water heater and no garden in the perfectly south facing fenced in backyard.
The target was LEED Silver certification through a Gut Rehab, but we quickly had determined that exposing the exterior or interior walls to air seal plus removing the shower and tub surround to add in a non-paper face drywall would go way over our budget. While LEED may fall more in line with a Deep Green Retrofit, we opted to do a Moderate Green Retrofit.
From there it was clear that the once called MNGreenStar program would make the most sense and they used it to document the existing conditions and come up with our goals to make the home better. As you can see in the initial energy audit in which they used was the HERS Model (think an MPG sticker for your house) and came out at 175. You can see a little more on results we got here. This number was on track with the old homeowners energy bills which we acquired during the audit. Their overall order of importance to the home upgrades was Energy Efficiency, Indoor Environmental Quality, Water Conservation, Landscaping and then Material Conservation.
They came across a unique financing that allowed them to do a lot of work in the up front while getting a longer return on investment, MI Saves had partnered with their gas company DTE to allow a $2,500 kickback to those who could show a performance plan of gas savings of 30% with an upgrade. Trane/WellsFargo also had a fantastic deal with a 0% 5-year loan that allowed other products outside of their brand to make up 50% of the costs.

Because this was a light remodel and weatherization they did not score too many material points. Materials are mainly for extensive work being done and refurbishment in existing homes.

Our blog details 1 years worth of utility date & costs associated with the project. It also features lessons learned. They will be keeping it up to date by monitoring the performance, durability, comfortably and maintenance.
They plan to achieve Silver Certification within 2 years by converting more of the backyard to a food garden and the entire front yard over to a mix of drought tolerant and native plant species along with raised bed food gardens. Adding rain barrels and fixing the gutters. We hope to achieve more points by painting the exterior of the house with carcinogen free no VOC paint.
Other current issues – No return ducts in the 2nd floor and some older ducts still panned in the joist may be causing temp swings in the second floor and higher summer humidity. We have an idea of opening up the kitchen to connect to the living and dining and during that time we could potentially add return ducts and seal the current ducts.
