Quick Perspective Sketches

Realizing I did not like how my brick was pasted to the front elevations of the studios and not allowed to go elsewhere, I have allowed the brick to wrap around the building in a gently sloping form, not typical to brick. The brick is underneath the second floor also, providing a surface for sliver shaped shadows to project. Next I will model the wrapping brick stair that will be consistant in language. In all of this, the glass is the back drop against which the brick moves. Considered entry slivers to pierce the projecting brick ledges. However, I think they are a bit too literal.

Wrap Stair

I am considering not expressing the landings with the wrap stair, but creating a sloping structure, that encompasses the landings. I feel this is more within the language of the building. I will potentially construct the wrap stair with glass on the steel frame which will cantileaver from the concrete structure of the tower. Instinctively, this may want to be some other material, but it wouldn't be brick, and metal panel is not used elsewhere in the building.

Studio Final: Site Plan

Studio Final: Site Plan

This is a preliminary post showing the first floor rather than the roof plan. At this point it is helpful to see the first floor.

1. Narrative:

In taking a closer look at the site, the ramp down into the parking garage will still be above grade, because of the slope in this area. I have enclosed the ramp and developed a roof top garden here, that connects to the boardwalk. The boardwalk allows very little about the grade to change, while bringing the pedestrian through the site. Several types of porous pavers are used, so that the percentage of impervious paving on the site has actually been decreased to the building footprint, which is less than the existing parking lot. Deciduous trees line the south facing facade, and evergreens will form a wind break to the north in the winter and diffuse some noise. A waterwall using captured rainwater is included at the entry/public green space, which will also mask noise and make the space more intimate. Slivers of green reach out into the sidewalk, and the largest sliver (between the buildings) is a green learning garden.

Insulation Locations

Brick and Curtain wall

The brick shown will be recycled brick that was recovered locally and has a SW grade.

Details

Here are a few sections of roof conditions.

Shown is a section through the main stair and the sliver bridge between the two buildings. Major design elements are labeled, future details will explain foundation connections, green roofs, and curtain walls, etc.

1. Mechanical Systems Description:

Passive heating and cooling will not be adequate to control the needs of the building. Additionally, the climate is somewhat humid and not suited for certain alternative methods that involve dry outside air. Therefore, the building employs the most effective passive solutions in combination with active green systems.

The building uses a combination of radiant hydronic heating and cooling that is contained in ceiling mounted panels and a natural ventilation system called Dedicated Outside Air System. Some of the advantages of this system include: Reduced chiller, condenser pump, and air handler size, reduced ductwork size and cross section, reduced electrical service during peak usage hours. The ventilation system provides 100% fresh air in lower quantities than required by air driven systems. The system regulates the flow of chilled or heated water by sensing room temperature and monitoring dew point. The thermal mass of the concrete slabs adjacent to curtain wall will naturally prevent large temperature swings and will work nicely in combination with the hydronic system.

Conversation with Chris Schaffner 9.05.07

Discussed:
Envelope- Recycled brick, sitecast concrete, green roofs, light-colored roof for residential

Lighting- Increased square footage of fenestration on north, west, and east sides of studios and gallery, will need sun shading for at least the west side

Heating/Cooling- Radiant hydronic heating/cooling is well suited to the spaces in combination with the thermal mass of the concrete structure. Boiler located in basement on exterior wall, with exhaust. Connections to smaller building will be made through a crawl space under the smaller building. Living areas will use some natural ventilation in combination with the above systems, since they will have lower cooling loads naturally. Exposed thermal mass on the east side of the residential tower corridor will contribute to the heating of that corridor.

Ventilation-I will be using a Dedicated Outside Air System which controls humidity, temperature and dew point for the smaller amount of fresh air that will need to be supplied to the building. Intake can be placed over green roof on larger building. Not on the smaller building, as intakes are noisy and it is meant as a peaceful place.

Energy Production- Photovoltaic panels on the roof of the residential tower will provide domestic hot water for the living units.

Generally, an understanding of the placement and parts of the system and how it moves through the building is desired. This will be described in detail in another post.

Studio Final: Structure

1. Structural Systems Summary:

Selection
This building will be constructed using Two-Way Flat Slab strategies. Two-way sitecast concrete was selected because of the needed flexibility for the irregular angular footprint of the building and the possibility to deviate from column grid up to 10% of the span. The system will allow for a fairly thin slab and the use of round columns. The round columns suggest the shape of the surrounding trees and add to the "forrest". Even though the round column needs to be larger in diameter, it is important to my design. The whole system provides noncombustible construction needed for a five story building. The slab itself will provide opportunities to utilize its thermal mass, especially on the east side of the residential tower, which will be curtiain wall.

Description
The building have a basement which will sit on a conventionally reinforced structural slab that rests on structural precast piles 80-100' deep, because of the waterlogged soil. 10' tall square columns will hold the first floor slab (10" thick). The first through fifth floor columns will be round, (although those which are burried in walls could be square). Column grid spacing will be roughly 30'x3o', with 14' tall columns on the first and second floors, and 11' tall columns on subsequent floors. All floor slab thicknesses will be 10". Edge columns will need to be 24" diameter and center columns will need to be 18" diameter. It may be desirable to use arrangements of reinforcing in the slab called shearheads to avoid overly large drop panel widths.

6" Non-load bearing precast insulated sandwich panels with brick ties will infill as the wall system, and recycled brick will be the veneer. This is true in several locations- not much differently than shown in previously posted renderings of the building. Other locations will use curtian wall, and the first floor will probably use a storefront.

The roof of the smaller building will be a green roof. I will be considering this tommorow and revising the post as needed.

The roof of the low portion of the larger building will also be a green roof, but will utilize the self irrigating low maintence grass roof tiles, introduced by Toyota, which do not require additional sizing of the structural system, because they are lightweight.

Update 9.05.07: I am no longer considering green panels as shown here for sun shading on the exterior. They will be brown in the winter, and vertically they don't block the sun in the right direction. I am considering green walls inside the atrium in the smaller building and possibly in temporary locations where they are accessible and won't be missed if taken down in winter.

Slivers

I can apply slivers in innumerable ways to this building- or I can let the sliver order the design logically. This is what I'm having trouble with- I can't move forward on technical aspects until I get this form at least partially nailed down.

Five Stories

Has anyone considered going up five stories? Are there any issues I should be aware of in considering this? I will be doing some more code research, but I thought I'd ask.
