When my mom tries to figure out what I do for a living, she asks “green bldgs – so, that means saving energy, right?”
Two kinds of clay were used, a smaller amount for the stucco or earth plaster – this was a gray clay from a nearby brick manufacturer that was $27. per ton delivered to the jobsite. 2 tons of this clay was used. A red clay was also used for the clay straw infill walls at the interior partitions. Approximately 80 c.y. of this red clay material was mixed onsite for these walls – this red clay material came from a home that we are constructing in the Fox Chapel area near the job site. These materials provide thermal mass which helps to stabilize the temperature of a building. The interior temperature of a high thermal mass building will not change as dramatically as that of a low thermal mass building. The 80 c.y. of clay straw infill added approximately 135,000 lbs of thermal mass to the building. The clay material also creates a hygric mass i.e. walls that can take on and release humidity – this should reduce the amount of energy needed to dehumidify the building. This is the latent cooling. Approximately 35% of energy used in cooling buildings in the Pittsburgh area involves latent cooling. The use of these materials dramatically swings the labor material equation that is more labor is spent and less material cost. While we do not believe that the use of these materials will achieve widespread use in the construction industry – investigating low embodied energy materials with increased thermal and even hygric mass would seem to have promise in reducing the carbon footprint of buildings during their construction and their operating cost for the useful life of the building. The office investigates the use of natural building materials for their low embodied energy i.e. that energy it takes to make and transport building materials to the site. The straw and clay used originated very close to the building site. The structure of the building is conventional steel frame and concrete slab on deck. The exterior walls are constructed of straw bale with earth plaster finished with a lime / sand stucco. Straw bale construction originated in the United States over 100 years ago. There are still buildings that survive from that time period. The interior walls are constructed of clay straw infill also known as cob, and this material has been in use for over 500 years.A porous concrete driveway was installed to allow for storm water management and to cleanse the water. i.e. Beneficial bacteria grow on the gravel below the porous concrete and clean any oil deposits that may occur.
Zinc clad deep window pockets provide shading from summer sunbut allow winter sunlight.the ground source, or geothermal wells, and the associated piping and pumps. Pump energy, which uses one tenth of the energy as fan energy, is used to heat and cool the building. During the winter the water to water source heat pumps are used to raise the temperature of the water. these are WSHP 2 – WSHP 4. They are not used during the summer – no matter how hot it gets the natural cooling is simply pumped through the slab tubing to cool the building. HP1 runs only during the most humid parts of the summer to de-humidify the building. There is also an ERV, or energy recovery ventilator, that brings fresh air into the building while capturing the energy of the outgoing air – it is like opening a window but having no heat or cooling escape. Finished building showing 2 acres of native plants that were installed by Robin Ernst of Meadeville Land Development using seed mix from her father’s business Ernst Conservation Seed Company.
In slab radiant heating was used to heat the building – and a first for the Pittsburgh area is the use of in slab radiant cooling. 6 - 450’ deep closed loop geothermal wells were installed at the site. These water source heat pumps will mine the heat from the 58 d f water in the winter. In the summer the heat pumps will be bypassed since the cool water can cool the building without the use of the heat pumps thus saving compressor energy. A 5 ton dehumidification system is used in the building to condition ventilation air. An energy recovery ventilator is used to mine the energy from the outgoing ventilation air and pass it into the incoming fresh air. Radiant piping in place. This tubing must be carefully monitored during construction to avoid puncture – it will provide both radiant heating and cooling.

Square footage did not change, but percentage did …. Kelly has details
We have actually gained 90,900 SF in total in signatures since the launch, but the number we had for ALCOA went down when they finally submitted their form. As Aurora explained to me, the number we previously had for them included their parking garage and the number we have now does not (which is the number we are going to use).In your presentation, you probably want to point out this fact that our numbers haven’t really changed and stress the importance of our data collection during the partner-forming process. All in all, because we are rounding for our number presentations, the total SF change since launch has been somewhat small compared to the total (100,000 SF change on 23.3 million SF total).

Since the MBA Sustainability was launched in 2007, it has consistently ranked among the top 25 in the world for social and environmental stewardship on the Aspen Institute’s Beyond Grey Pinstripes’ survey. The program is among the elite MBA programs accredited by accredited by AACSB-International.
Our MBA Sustainability program is aligned with the United Nation’s Principles for Responsible Management. In fact, we were among the initial signatories of this Global Compact. One year program, has two international study abroad trips (maybe Russia would be a destination in the future) and each student will have three consulting projects during the year.The program is grounded in the ethical management of social, economic and environmental resources. We’re among the elite 5% of MBA programs accredited by AACSB-International The curriculum combines rigorous coursework in all the traditional business disciplines while applying and integrating learning through cross-functional integration, professional development , global study trips, and field projects. Our graduates have the analytical and communication skills to solve real problems and inspire productive change.
The point here is that we are not just doing sustainability / green building at our new campus—we are infusing it across our locations, have have been doing so since well before we received the Eden Hall property.
Only about 30 schools in the US have achieved GOLD in the AASHE certification process. I was somewhat surprised to see my name in USA Today—we were listed as one of four schools who go “the extra step” for sustainability. We were even more surprised and pleased to be in Forbes, recognizing the business importance of sustainability/green building.
We now have 90 students in two programs: Master of Arts in Food Studies and Master of Sustainability. In Jan 2014 we hope to launch the Executive Master of Sustainability Leadership, and in Fall 2014 we will welcome the first class of the Bachelor of Sustainability. All programs are very experiential, with lots of problem based learning, client-based research, projects, as well as focus on communication and teamwork.
With our three locations, we work with a variety of communities as sustainability partners.
Master plan was approved by Richland Township in 2011. We have been growing food and teaching sustainable agriculture since then.
This and the following four slides explore the energy, water, and food systems. Hopefully self-explanatory for you.
Amphitheater is nearly finished, will be officially open in mid-October
Field lab shows contructed wetlands to the left, edible landscaping to the right. Will be open in October.
We would be thrilled to have this idea of a center for urban sustainability be part of your conversations in Moscow.
We have the Technology, Resource understanding, and People – these are NOT the issues.
We do not have the data (1) on actual performance; 2) on payback hx of loans; 3) on future (appraised) value of equipment and buildings), the financing or proven product:
But mostly we don’t care enough…but I submit that there are really only three reasons why people care…
We won’t win by preaching, by being the scold. We win by relating to people where they are. Where they have FUN.
There are lots of doors through which people might pass to reach “sustainability”
Think Healthy and High Performance, not Green

I started VO and KP to get people outside and give them a reason to care.

You have a sense of self – you already live there and get feedback every day. But what about the rest of your “self”? The places where you exist? One needs to develop that Sense of Place!
