Natural Ventilation?

For any of you still struggling with passive vs. active space conditioning, here's a helpful flow chart that will assist your decision making process. It comes from a UK publication called " Natural Ventilation in Non-Domestic Buildings".

Incidentally, 30 - 40 W/m2 translates to 2.8 - 3.7 w/sf. Typical internal loads in an office building are 1.5 -2.5 w/sf before any envelope gains are included, so your building has to be pretty efficient to have any chance of making it work.

I will have "office hours" next Wednesday afternoon (9/5) from 2PM to 6PM EDT. If you wish to meet with me via phone, send me an email with your preferred 30 minute block.

CS- Week 4 - the radio silence continues

Sorry folks. I had you give me permission to post to your blogs. Thanks for that. Unfortunately there is some bug in the blogger software; whenever I try to post something on your blogs the software reverts back to my own blog. And I spent way too much time trying to figure out how to make it work. So, I'm trying something else. Stay tuned and please elevate and detail sketch.

CS - Week 4 - next steps

Hi all, sorry for the radio silence. google shut me out of my own blog for awhile...
I hope this doesn't happen for any of you.
Everybody has a slightly different path from here on. I need a bit more time to put together individual requests. But in the meantime we all should be pushing elevations, material and the beginnings of key details. Even if the plan changes, these elements will stay the same. I would like you to elevate at least the north and the south facing elevations, annotate for materials and rough sketch material transitions at ground, at a window, at the roof. The more the marrier. Posting a plus.

CS - Week 4

Hello everyone. I hope you all had a great trip home and caught up on some sleep. I know I haven't yet.

Please read the Final Blog Requirements under Course Documents and give Chris and I permission to post on your blog (see attached image; it should look similar). Thanks

AT Office Hours

Sorry to bug out early last night. If anyone needs some of my time, I will have office hours from 11:30 - 1:oo today.

solar chimney + wind generation

Here's a "real" version of the solar chimney + wind power I was describing last night. It's a project in Australia.

CS - Week 3: Parti (2)

A successful parti would answer a most of the following questions:

Site: - Access: Main Entry. Service Entry. Parking
- Topography: Main Elevation, how to make up drop on site
- Open Space: Leftover. Main feature

Geometry: - City Grid
- Transit Route
- Free standing / attached
- Object / Part of row

Program: - How many levels --- Footprint
- Expressed / Imbedded
- Where on site are major program elements
- How do major program elements relate to each other

Reactions to site influences:
- Transit, movement and noise
- Pedestrian movement
- Neighborhood qualities (grid, mass, materials, texture, etc)

My ecological footprint

Here's my ecological footprint

Despite my hybrid car, all those plane flights and the big house in the suburbs take their toll.

Of course the quiz doesn't asking me questions like: "What kind of electricity do you buy?","Is your house air conditioned?", "Do you recycle?", "How much insulation do you have".

In fact, the quiz makes many assumptions, and uses national averages in many places (try changing your location, and nothing else), so recognize it for what it is - A crude tool, designed to get our conversation started.

CS – Week 3: Parti

If you would have to design a user guide for a surfboard, this would be the parti.

The parti organizes the program on the site, arranges the major geometries, establishes hierarchies, assigns major materials, locates main elements.
Choose goals from your vision statements, weigh them in importance and put together sketches to develop a parti. By changing the goals and the assigned weight, you will be able to develop different parties. Several parties will be required. Use plans, sections, models to best represent the essence of the parti.

CS – Week 3: Vision

You already developed three+ environmental goals, you had an introduction to structural design considerations, and you visited the site. You know your program: living working, exhibiting for the intensive portion of a long distance learning program.
Now it is time to develop a vision for your project.
Determine three goals each for:
- the site.
- the program
---- livning quarters
---- working environment
---- exhibit / connection to community
- the neighborhood / community
- the "world" community
- the time we live in.
Discuss in small groups, determine goals (if you can’t agree on a common gaol, define your own), find images and/or descriptions to document your goals, document.
This vision will be the thesis of your project. It will be the benchmark for the rest of your semester.

CS - Week 3: Site

The site for the remainder of the semester is near the BAC in Boston: Walk up Newbury Street, take a right at Massachusetts Avenue and cross it, at the intersection with Boylston Street is our site.
It is bound by the MBTA commuter line next to the Massachusetts Turn Pike, Massachusetts Avenue, Boylston Street and a parking lot in the adjacent lot.
The site is currently occupied by a vacant, fenced-in parking lot and numerous wild growing trees. A gentle slope follows Boylston Street and across the site to a sudden drop down to the rail line.
The portion of the lot we will be working with is ca. 19,400 sf.

AT - Week 2 Assignment is posted

CS - Model making material for Boston

Some of the instructional courses will build models. Bring your tools. Sketch models are always an additional tool to drawings to proof to yourself and communicate with others. As much as I'm not requiring
Models, by now in your career you probably know if you benefit from the use of it. The quality models you created in the first semester might be very handy. Materials are available a block away from the BAC.

CS - Week 2 - Sample Program Documents

The first image shows excerpts of a verbal description of a program for a dorm we received from the client. The second one is a sample of an office program report, showing department, type space, quantitiy.

The third is a sample from a building program, listing type, space and area, as well as a total. The combination of the three is what you will need to have a good program document: a brief description of the spaces and uses the facility will need, area assignments and adjacencies, as well as a grand total, so we can start with the massing.

comment to karrick

red flag (pole and banner) overlaps blue flag. right angled wall creates transitional spaces. The space (highlighted in red) is particularly interesting: The large space 1A & 1B is defined with the wall sitting out in the outside (?). The exterior space with little definition (only the corners are marked) is stopped by the row of columns near the red "pole". In between a space that is trully transitional: part in space 1, inside, part exterior, outside.

CS -Week 2

As we are starting week 2 you should be wrapping up the week 1 assignment. To signal that you came to an end, format it on a product sheet, as outlined in the “deliverables”. Don’t forget the narrative.
The assignment for week 2 is now published.

CS - WEEK 1 - End in sight?

So far terrific work.

Let's tweak it some more and make it concrete.

Don't forget to check your classmate's blogs; it counts.

AT - Introduction

Greetings.

As you may know this is not one class, but two.

I am Chris Schaffner, the instructor for the Architectural Technology portion of the course. My role, and goal, is to help you bring an integrated approach to your design projects. Good architecture is about function as well as form, and must include a consideration for the building occupant's comfort and well being, along with an appreciation for environmental stewardship. That's what where going to try to do.

But enough hoo-haw. If you want to learn more about me, check out my company's website - www.greenengineer.com.

I have posted your first assignment (it's there in the upper right). Have fun.

Chris

CS - WEEK 1 - TRANSITIONS

Judging from the first postings on your blogs, I think I need to add an additional explanation:
Compare to the images in the assignment sheet.
The abrupt transition between two spaces happens without forewarning: somewhere in a space defining element there is an opening that leads to the next space.
The lead transition introduces a space defining element common to both spaces.
The gradual transition uses a space to make the transition. Being in the transition space, there I is a moment when you are in two spaces at the same time, space “A” and the transition space. Steps later you are in two different spaces, space “B” and transition space.
Compare to the transitions you created in your models.
