MASTERPLAN

Site Water Retention

Ryker Hoy

Relevant Information:

The goal that the class has set for the site is an even 50/50 split of rooftop water collection and green, usable space. This will suggest a very balanced, sustainable15-Minute City.

The diagram outlines where every green roof and water collection roof is located at in the15-Minute City. The integrated infrastructure to green roof space suggests both public and private spaces for people to use at there convenience. The water collection roofs are also strategically placed on the site to achieve the maximum water collection. This is normally located at the tallest parts of buildings. These spaces would not be accessible to people giving them full capabilities for water collection.

Sector Goals

Platform Sector Goals

Blake Phillips

Relevant Information:

Based on preliminary information gathered before beginning our urban design phase and the location of our sector within the site as a whole, we have identified key elements we wish to accomplish through our massing arrangements.

Analysis:

Our site is the heart of the 15 minute city and serves as the anchor which connects all the other sectors to each other. By bridging over O Street we allow for pedestrian circulation and a primary vehicular thoroughfare coexist.

Sector Goals

Elevate Pedestrian Circulation

Create a pedestrian only environment to break up the verticality of the surrounding buildings.

Bridge Across O Street

Build a prominent urban destination within the 15 minute city.

Create Diverse Environments

Form pockets of greenery, program, and circulation to provide a safe oasis from the much more busy streetfronts below.

Connection to Surrounding Sectors

Bring together multiple surrounding sectors into the heart of the 15 minute city.

Atmosphere

Phillips

Relevant Information:

Through the platform we seek to create various group seating environments and access to greenery in order to provide an oasis from the much more busy street fronts below. We also seek to create a pedestrian promenade through the center of the site which will feature bars, restaurants, and night life. The goal is to activate the platform through all hours of the day with office workers during business hours and visitors to the pedestrian promenade and theater after hours.

Relevant Information:

Location: Omaha, NE

Designer: Leo A Daly

Size: approximately 200,000 sq/ft

The 200,000-SF office campus features two, fourstory glass towers joined by a two-story amenity zone. Inside the amenity zone, named “Carson Commons,” visitors and Carson employees, known as “stakeholders,” will dine, socialize and nourish their health with café and fitness amenities.

LEO A DALY’s design for Carson headquarters earned the moniker “Ascend” based on its upwardsweeping rooflines, which reference Carson’s “guided by growth – live life by design, not by default” value. The development of the structural framing system used cantilevered steel members to enhance the “Ascend” design concept. When viewed from the north and south facades, the cantilevers project a “hovering” quality while minimizing vibrations for the open-office setting.

Integrated amenities such as courtyards, a rooftop terrace and the central amenity zone reinforce Carson’s passion for its people and its obsession with the client experience. Carson’s “family” philosophy toward its employees informs the interior design. Public areas are designated as “living room,” “front porch” and “kitchen table,” and the materiality is light and open, with natural wood accents lending warmth, like an invitation, especially when made visually prominent by streams of daylight.

Key Takeaways:

Programatically would like my building to match much of what was accomplished in the Carson Building. I would like to include public areas/ammenties such as the roof deck, fitness center, and company bar. Architecturally, the two-story artrium space within the Carson building is simlar to what I would like to achieve with my lobby entrance. The use of a sit/stand stair is an interesting way to make the space more usable/ flexible. Carson group took the approach of two building with a connecting ammenities zone. Similarly, my tower should feature a primary tenant with several smaller tenants separated by an ammenities floor. The use of photovoltaic glass is also an interesting solution to sustainability that I would like to include within my design. Photovoltaic glass allows for the building to intelligently respond the the changing conditions of the sun, while also allowing for maximum transparency in areas where the sun is less intense. The photovoltaic glass also allows for a more consistent interior lighting environment within the building at all times of the work day.

Design Process

Relevant Information:

Design process began with a single-skin glass facade and a series of orthographic and 45 degree diagonal mullions to generate interest while driving in on O Street.

Design Process

Relevant Information:

Design on North facade continued development to mimic design on the East and West facades.

Design Process

Relevant Information:

North facade was developed futher to create visual connections between the East and West facades through connecting diagonal moves.

Design Process

Relevant Information:

“Crosshatched” mullions were removed on the North facade leaving only the major connecting diagonals. This was done because the North facade receives the least amount of direct sunlight, and the removal allowed for less-obstructed views. The use of a spider clip and cable system contributed to this goal of unobstructed views from the North. DoubleSkin facade design with two sets of mullions began devlopment to more easily create slab-wall-mullion connections.

Design Process

Relevant Information:

Development of upper south facade to mirror the design on the North. More crosshatched mullions added to upper south facade for sun shading. Lower south facade and south half of east and west facades use typical vertical mullion system because they are shaded most of the day by surrounding buildings and are not readily visible from O St. Pedestrian zone developed with spaces for bars and restaurants on ground level.

Design Process

Relevant Information:

Colors of the major diagonals were changed to reflect the primary building tenant. Building is bisected by the ammenity floor. PV glass is pulled back 6 feet on ammenity floor to create a walking track around the tower and to differentiate primary and secondary tenant spaces. North facade carried around building on ammenity floor to create unimpeded views on ammenity floor.

Double Skin Facade

The building utilizes an mechanically ventilated double-skin facade which improves thermal and acoustic insulation while allowing clear views and natural light.

Mass Timber Construction

The building uses CLT-concrete composite slabs and glulam columns and beams which allows for long-term carbon sequestration within the structure as well as a faster construction timeline. Exposed timber within the building contributes to a healthy work environment through biophilia.

Electrochromic Glass

Electrochromic Glass helps to reduce solar heat gain, and reduce glare on screens throughout the day creating a more comfortable work environment while still allowing for views and natural light.

Solar Shading

Additional mullions on the South, East, and West facades help to further shade the building through bespoke diagonal moves

Water Collection

365,084 gallons of greywater collected per year (assume 62% collection e ciency) Accounts for approximately 11% of total water consumption

Solar Energy

186,770 KWH energy produced per year Accounts for 8.5% of estimated total energy consumption per year

Plans

East Section

Relevant Information:

The East and West Facades feature a dual mullion system. The interior mullions are a typical vertical mullion system for ease of slab-mullionwall connections. The interior mullions feature photovoltaic glass which can darken and adapt to solar conditions throughout the day. The secondary mullion system or design mullions follow a nonstandard angled design. The primary diagonal connections of the design mullions are blue/green with secondary “cross hatched” white mullions which help to further shade the interior of the building. The design mullions have spider clips which allow for a secondary clear layer of point-fixed glass. The upper south facade is also similar in design to the East and West in buildup. This is an “active” doubleskin facade system meaning that the internal zone between the two layers of glass is mechanically ventilated.

Details

Relevant Information:

The North facade features a dual mullion system. The interior mullions are a typical vertical mullion system for ease of slab-mullion-wall connections. The interior mullions feature photovoltaic glass which can darken and adapt to solar conditions throughout the day. The secondary mullion system or design mullions follow a non-standard angled design. The diagonal connections of the design mullions are blue/green. The secondary “crosshatched” white mullions seen on the East and West facades were removed to allow for the most unimpeded views. Instead, the North facade utilizes a spider clip, cable, and rod system. The two layers of steel cables are held tightly under tension and connect to steel rods which hold the spider clips in place. This is an “active” double-skin facade system meaning that the internal zone between the two layers of glass is mechanically ventilated.
