Presentation to YES summer program at Middle School in New Rochelle NY. Purpose of lecture was to familiarize middle school students with what architects and engineers do. The presentation also discusses the basic concepts of green building design. After the PowerPoint, and as shown on the last slide, a lab was held where the students built a cube out of K'Nex building toy. Three experiments were run. One with cube with no bracing. The cube was loaded with text books until buckling or joint failure. The experiment was repeated, once with one way bracing, and then again with two way bracing. The load results followed an approximate exponential curve. This was a real world demonstration of the enormous increase in capacity of a frame joint through the use of diagonal bracing.

- 1. ARCHITECTURE PRESENTATION FOR Y.E.S. ALMS JULY 13TH, 2011
- 5. What is Architecture? Architecture is the imaginative blend of art and science in the design of environments for people. People need places to eat, work, live and play. Architects transform these needs into concepts and then develop the concepts into building images that can be constructed by others. These projects can be as small as an entrance way and as large as an entire college campus—and everything in between.* between. *http://www.archcareers.org/HowToBecomeAnArchitect.pdf
- 7. What is the difference between Architecture and Engineering? Solves: not clearly defined (or ambiguous) problems. For example what is the best place in a building for a column, what shape should it be when I look at it? How does it make me feel? Solves: highly complex well defined problems. For example what exact size and shape column is needed to hold up a roof so it does not collapse? Art Science
- 8. What are architects all about? a careful listener - So you can understand your client and what they need. a good communicator - Explain your ideas and express them – writing – drawing - etc. a leader - Inspire others on the building team to strive for excellence. a good citizen - Express ideals of society. Ethical. Promote Sustainability. a good problem solver - What is the right question – creative approach – outside the box a protector - Safeguard health and safety by designing to building codes a business person - Spend client’s money wisely, manage your own money.
- 9. What is green Architecture? REDUCING IMPACT ON THE ENVIRONMENT • Reduce consumption in building Energy Energy to operate building Energy for people to get to and from building Energy for bld’g. materials to get to site Fresh Water Materials Building Materials Operating Materials • Reuse Waste leaving building Waste Energy Waste Water Human Waste Ruse old buildings for new purposes Reuse old building materials Construction Waste • Improved Environment within the Building Reduce indoor air pollution Maximize building occupant comfort Quality Ventilation Maximize natural light and views
- 10. Owner has a need. They pay for Architect’s time to design building plans. Owner also pays Contractor to construct building. Owner must request Green Architecture. Designs the building – solves the owner’s need – prepares drawings to show design ideas for contractor. Builds project according to architect’s drawings. Is paid directly by the owner for work completed. Architect must be trained in design of Green Architecture. Contractor must understand special aspects of design for Green Architecture Owner (Client) Architect & Engineer Contractor

- Coincidentally, after posting my last entry about dollhouses, I stumbled across these photos of an abandoned farmhouse in Saskatchewan, Canada. Canadian artist Heather Benning tranformed this scary house into a life-sized dollhouse a couple of years ago. The back of the house has plexiglass walls to create the doll-house view. I really like Benning's choice of pastel wall colours and 60's style furniture.This is a very cool concept but I don't think I would be brave enough to live so exposed on a cold and windy Saskatchewan night.Of course, the house was never intended to be lived in. The art installation will be left intact until the house becomes unsafe.
- Does anyone know what “Green Architecture” is? Here is a quote that I got from a website, which I think it pretty good: “Green architecture, or green design, is an approach to building that minimizes harmful effects on human health and the environment. The "green" architect or designer attempts to safeguard air, water, and earth by choosing eco-friendly building materials and construction practices.”* *http://architecture.about.com/od/greenconcepts/g/green.htm
- This is the Lehman New Science Facility. It will be opening in the spring of 2012. This is a rendering prepared by the architect, Perkins + Will of New York City. This is a view from the main college walk. You can see a greenhouse on the roof. Bridges will linked the new building back to the older building.
- This is a view of the main entrance. There will be an entry atrium with a grand staircase. In order to control the large amount of light, and corresponding heat entering the building through the atrium glass, the architects incorporated several design features. The right hand glass façade faces north, protecting the atrium from overheating in the spring, summer and fall. They also designed the glass with a screen pattern that is permanently painted onto the glass. This is kind of like a built in sunshade, blocking a portion of the entering light, but still letting you see in and out. This is a scan of the glass sample submitted by the contractor and approved by the architect for the atrium glass. It’s also interesting, the density of the dots is actually different between the left, or east facing atrium glass and the right or north facing glass with a higher density facing east where there is direct sunlight for the first part of the day. They also specified high efficiency double paned glass windows which helps to keep heat or cool in the building. All of these features are part of the Maximize Energy Performance Credit under Energy and Atmosphere. A sophisticated computer model of heat flow is created for the building as a whole and is run under differing conditions, this is typically performed by an engineer who specializes in this type of computer modeling. Each component of the exterior walls are input. These results are then submitted as part of that credit in order to demonstrate the level of increased energy efficiency.
- This is a view of the inner courtyard. In the future there is planned to be a constructed wetland which will be a form of natural waste water treatment system. It will be a living laboratory for the scientists who work here as this is an area that Lehman researchers deal with.
- Here is another view of the courtyard.
- This diagram shows how this building will reduce the amount of freshwater it takes from the New York City water system. There will be two sources of water that is typically dumped out of a site. The rainwater that falls on the roof will be collected and a portion of it will be channeled to storage tanks. Water from sinks and water fountains will also be directed to these tanks. The water is now termed gray water. It’s just a little dirty. You can guess what the term black water refers to. This gray water is recycled by being naturally filtered. It then gets reused for both irrigation of the landscaping and to be used for flushing toilets.
- Here is a photos of the building under construction.
