Urban Situation The mapping shows that the site is located at the south of Detroit close to the water. The project site is a very important one because of its node-like location in between Downtown and East Detroit, and its position at the entrance to the popular Belle Isle. Spanning from Downtown to East Grand Boulevard, the city of Detroit has engaged in a Riverfront Development to better connect, and engage the neighborhoods.

In addition, the building has in general a taller south facade not only because of the expected heat efficiency but also a generous open view towards the Detroit River/Belle Isle scenery.

Massing and site coverage
Site Plan
3. To achieve a desirable FAR, we chose to take a majority site coverage at 63% but began to break up the mass to not only provide an elevation green space for the public to enjoy, but also the logistical inner circulation and egress. This resultant form gave way to the townhome-sized units ranging from 1-story to 3-story lofts, totaling 125,290 square feet.

2. Our proposal aims to respond to the entrance position of the Belle Isle adding new dedicated bike lanes to connect to the new Beltline Greenway, as well as a public elevated greenspace to overlook the river scenery.

1. Light pocket on the Valley 2. Roof sky lights 3. E-W axis orientation
Design Narrative:
summer
The overall mass, matching the approximate height of the adjacent apartment complex and old mansion, situates itself within its context. Orientated along the E-W axis, the peaks block harsh east and west sun while the southern sun projects a shadow play along the valley. In addition, the building has in general a taller south facade not only because of the expected heat efficiency but also a generous open view towards the Detroit River/Belle Isle scenery.

Design Narrative: ADA access to Valley access to Garage
We propose an Above ground parking strategy under the Valley because of an integrative design discipline that is generated the geometry of overall buidling mass. Each unit on the ground level has direct access from the interior space. Whereas each upper unit has acess to the Valley that is above and connected with this garage space by the elevators on both ends. Plentiful bicycle racks are also provided in the garage spae to adapt to contemporary and future low-carb living style. 1 ADA parking stall is located next to the ADA onestory unit on the east side. 4 Van-accessbile stalls are provided at the northwest corner to increase convenience for both the residents and the store.

Type IV Zone 1 90 mph 100 psf 20 psf CLT Timber 90 Minutes
Design Narrative: Our project is classified under Type IV Construction, with using CLT as the heavy timber requirement for the roof, floor, and interior bearing walls, while the exterior walls consist of a 2-hour noncombustible assembly. CLT was chosen by our team because of its ability to seclude carbon, its renewability as a material, its aesthetic as an exposed structure, as well as it’s lightweight. Our walkable valley will operate on a separate structural system of two-plate concrete and 16” x 16” square concrete columns. This is due to its heavy dead load of earth, water, and snow, and unpredictable live load of pedestrians.

Active Environmental Systems Design (HVAC) Integrated Systems Design Summary Our environmental systems will be taking full advantage of our steep gabled roof by collecting rainwater through an integrated roof drainage system. This rainwater will then be pumped to an underground water storage tank, which will be constantly kept at a cooled temperature through the method of Direct Cooling. The water will then be pumped directly to the radiant floors for cooling distribution or be directed to the unit-individual boilers for proper heating. This system of collection, conversion and distribution will be used as needed for our radiant floor heating/cooling system as well as plumbing fixtures.

Active Environmental Systems Design (HVAC) Mechanical Ventilation Design Summary Our ceiling mounted, unit-individual air handling units will allow for external air to direct enter the ventilation system and either be cooled or heated before entering the space. A heat recovery ventilation system will allow for a large reduction in heating energy due to the external air being pre-heated by the room’s return air. This system will also reduce loads for cooling and dehumidification. Natural ventilation will also play a huge role during the desirable summer months in Michigan. The first and second level units will utilize a stacked ventilation method while the upper units will have the access to cross ventilation.
Integration of Ventilation
Energy Distribution Design Summary As water is pumped up from the underground water storage tank, it will diverge one of three ways: 1. Directly to plumbing fixture or radiant floor during summer months 2. Into the boiler-fed warm water tank to later be distributed to the hot plumbing fixtures 3. Into the boiler-fed water tank to later be distributed to the radiant floor during the winter months.

Allow the sun’s warm rays in and heat up energy savings. When the cold of winter comes, nothing feels better than the sun’s warming rays through big, bright windows. The new low-E from Guardian – ClimaGuard 72/57 – incorporates a passive solar heat concept to provide a powerful level of insulation against winter cold, while selectively letting warm sunshine into the home as a free and sustainable heat source.
ClimaGuard 72/57 – flip it for versatility Choosing ClimaGuard 72/57 can provide manufacturing versatility by meeting ENERGY STAR® requirements in the Northern U.S. Zone on the #3 surface and, by flipping the IG unit and orienting the coating to the #2 surface, meeting requirements for the North-Central Zone.

With only one window type being operable, this left more design freedom to place windows at any sill height. This allowed, in some instances, almost full floor-to-ceiling windows to allow massive amounts of light to floor the unit. The jamb and sill details will match those of the surrounding context by being painted white, including an insulated wood frame. Guardian’s ClimaGuard 72/57 #3 has been chosen for all the glazing in the project due to its low-e film and high SHGC (solar heat gain coefficient.
