Residential Lounges- at the landing of residential elevators floors 2-6

Group A-2 per § 303.3 is for assembly areas where food and drink are consumed. The requirements for these occupancies presume that alcoholic beverages may be served, thus potentially impairing the occupants’ responses to an emergency. It also presumes that chairs and tables will be loose and may obstruct or make unclear egress pathways for patrons. The requirements also recognize the poor fire history of such occupancies. Group A-3 occupancies per § 303.4 are assembly areas that do not fit into the other Group A categories. It also includes spaces used for worship, recreation, or amusement. The intent of this classification is that any use that seems to be an assembly occupancy and does not fit the criteria of the other four Group A categories should be classified as an A-3 occupancy. Group A-5 occupancies per § 303.6 are assembly areas for the participation or viewing of outdoor sporting events. The occupancy group includes incidental storage, which will be regulated per the mixed use provisions in § 508. Accessory occupancies are regulated by § 508.2 and must still be individually classified. Larger storage areas would be classified as Group S. Typically for larger combinations of M and S occupancies, the non separated provisions of § 508.3 are used. Group R-2 occupants are permanent, sleeping in buildings containing more than two dwelling units for more than 30 days. These include apartments, dormitories, and long-term residential boarding houses. Congregate living facilities with 16 or fewer occupants (note the cutoff is 16 or less) are permitted to comply with requirements for R-3 occupancies. § 406.4 classifies public parking garages into open parking garages and enclosed parking garages.

Type I-A The building is a 27 story residential tower with multiple indoor recreation centers on a 1.5 acre site in Detroit’s Old Redford Neighborhood. It has a concrete frame and a stone rain screen veneer. The construction type is I-A. The building is a mixture of separated uses including primarily R-2 apartments on levels 3-27, large A-3 recreation areas without assembly, public spaces A-2 on levels 2-6 and M retail on levels 1 and 2. These are separated by a 2 hour use separation, which allows the area and height limitations from Table 503 to overlap. The overall building construction Type is I-A, which allows for unlimited floor plate size and height for all occupancy groups See section 302.3

What is the fire rating of the perimeter walls due to 7 building location on site? Reference Table 603.

As per Table 602 the exterior wall is required to be rated for 1 hour on all sides except those facing the courtyard, as the Fire Separation Distance is 5<x<10 feet using Type I Construction

Describe any fire sprinkler systems used. Reference Section 506 for any allowable area increase and note 8 here.

Installation of an automatic sprinkler allows for an increase in maximum height by 20 ft or 1 story, allows for unlimited per floor area, and allows for only one required means of egress for group R-@ occupancy apart units. The automatic sprinkler system also allows for decreases in minimum requirements for egress width, clear space between handrails for degree, etc.

As per Table 602, the building elements are required to be rated for 3 hours in Type 1 construction, and in the case of concrete construction, the structural members must follow the dimensions as per Table 602.4

Use and Occupancy Classification Section 302 Classification Residential Lounges- at the landing of residential elevators floors 2-6 Indoor Recreation Centers- on levels 24, 6, 4, and 3 Outdoor Recreation Areas- at northeast edge of site above parking garage

Group A occupancies are typically defined as having 50 or more occupants. Per § 303.1.1, assembly areas with fewer than 50 occupants are to be classified as Group B Occupancies. Assembly areas of less than 750 sf (69.68 m2) that are accessory to other uses are also not considered as Group A areas per § 303.1.2 Item 2.

Group A

Retail- on floors 1 and 2

Uses in these groups are fairly self-explanatory. The occupancy group includes incidental storage, which will be regulated per the mixed use provisions in § 508. Accessory occupancies are regulated by § 508.2 and must still be individually classified. Larger storage areas would be classified as Group S. Typically for larger combinations of M and S occupancies, the non separated provisions of § 508.3 are used. Residential occupancies include typical housing units, distinguished mainly by the total number of occupants. A key criterion for this type of occupancy is that the occupants sleep in the building. This group also includes smaller-scale institutional occupancies that fall below certain thresholds for the number of occupants. Storage for materials with quantities or characteristics not considered hazardous enough to be considered a Group H occupancy is classified as Group S.

Special uses and occupancies The definition of a high-rise building in §403 is based on the height that typical fire-department extension ladders and hose streams can effectively fight a fire. Thus a building with an occupied floor more than 75’ (22 860) above the lowest level of fire-department access is defined as a high-rise. Firefighting in a high-rise assumes that the firefighters must enter the building and go up inside the building to fight a fire. BUILDING EXCEEDS 75’ (305’)

Motor-Vehicle-Related Occupancies

Enclosed parking garages are similar to open parking garages except that the amount of wall enclosure relative to the building area does not allow them to be considered as open garages. Because they do not meet the criteria for open parking garages and are considered enclosed, mechanical ventilation is required to 2 story underground enclosed parking compensate for the lack of cross-ventilation. structure

503.1.3 states that Type I buildings, permitted to be of unlimited height and area per § 504 and § 506, do not require the mitigations for unlimited-area building imposed on other construction types by other sections of this chapter. Note, however, that certain Group H occupancies have height and area restrictions even for Type I buildings. no group H occupancies

Section 506 Area Modifications

General. The areas limited by Table 503 shall be permitted to be increased due to frontage and automatic sprinkler system protection, in accordance with the 506.1 following: Chapter 6

Types of Construction

The building has frontage of at least 30 feet on all sides and fully sprinkled. The sprinklers are not being used for a rating substitution in accordance with Table 601. The allowable area for A-2 use in Type I-B construction is 9,500 sf. With the use of Equation 5-1, this area increases to 35,625. Using the equation with only the sprinkler increase results in an allowable area of 28,500 sf - which is over the area of the ground level (26,250). Comments

Chapter 7

Fire Resistance Rated Construction Section 702 Definitions 702 Fire Separation Distance The distance measured from the building face to the closest interior lot line, to the centerline of a street, alley or public way, or to an imaginary line between two buildings on the lot. The distance shall be measured at right angles from the face of the wall.

All the sides of the building have a separation distance greater than 30 feet; the required rating for the exterior walls is 0 hours.

Section 704 Exterior Walls Table 704.8 Allowable Opening Area for Exterior Walls § 704.8 prohibits inclusion of service elements such as pipes or conduits into the fire-protection covering. This recognizes that such elements can conduct heat through the fire protection to the structural member and thus potentially compromise the time rating for fireresistance. 704.8.1 Automatic Sprinkler System In buildings equipped throughout with an automatic sprinkler system in accordance with Section 903.3.1.1, the maximum allowable area of unprotected openings in occupancies other than Groups H-1, H-2, and H-3 shall be the same as the tabulated limitations for protected openings.

Chapter 10

The buildings are fully sprinklered and the openings in the rated perimeter walls will be unprotected. All areas of the building perimeter have a fire separation distance of greater than 20 feet. Per Table 704.8, there is no limit to the area of openings on the building.

Means of Egress Comments § 1003.7 does not permit any of these modes of transportation to be used as components of a means of egress. The only exception is for elevators used as an accessible means of egress per § 1009.4, where they are provided with standby power and also with operation and signal devices per § 2.27 of ASME A17.1. § 1004.1 specifies that means-of-egress facilities for a building are to be designed to accommodate Section 1004 Occupant Load the number of occupants as computed in accordance with § 1004.1.2 and Table 1004.1.2.

Per § 1004.2 occupant loads may be increased beyond those listed in Table 1004.1.2 as long as the means of egress system is sized to accommodate the occupant load. In no case may the occupant load calculated under this provision exceed one occupant per 7 sf (0.65 m2) of occipiable floor area. § 1004.1.1.2 applies the principle of convergence to the means of egress from a mezzanine, based on the assumption that some of the occupants of the mezzanine will pass through the floor below to get to a common set of exit paths and thus are added to the occupant load. When other egress paths are provided, those occupants need not be added. Mercantile space occupant load factors in Table 1004.1.2 have been revised so that the same factor is to be used for these spaces no matter what floor they are on. The factor is 60 sf (5.6 m2) per occupant, gross. § 1004.3 requires assembly occupancies to have signs posted in a conspicuous place showing the occupant load. This is to prevent overloading of the spaces, which could impair exiting in a panic situation. § 1004.5 states that outdoor areas, such as dining patios behind restaurants, are to be included in occupant-load calculations and provided with exits. When it can be anticipated that the occupants of an outdoor area would be in addition to those occupants inside the building, this occupant load must be added to the egress capacity calculations. When the occupants can be expected to be either inside or outside, but not both, the capacity need not be additive. § 1004.6 covers the means-of-egress requirements that apply to buildings housing multiple occupancies. When there are special egress requirements based on occupancy, they apply in that portion of the building housing that occupancy. When different occupancies share common egress paths, the most stringent requirements for each occupancy will govern the design of the means-of-egress system.

Section 1005 Egress Sizing

§ 1005 specifies that the capacity of exit pathways be governed by: the occupant load, the hazard of the occupancy, whether the building is sprinklered, and whether the path is a stair or other component of a means of egress. 1005.1 Minimum Required Egress Width The means of egress shall not be less than required by this section. The total width of means of egress in inches shall not beless than the total occupant load served by the means of egress multiplied by the factors in Table 1005.1 and not less than specified elsewhere in this code.Multiple means of egress shall be sized such that the loss of any one means of egress shall not reduce the availible capacity to less than 50 percent of the required capacity. The maximum capacity required from any story of a building shall be maintained to termination of the means of eqress. 1005.1 Egress Width Per Occupant Served Occupancies other than H and I Stairways: 0.3 inches per occupant. Other egress: 0.2 inches per occupant.

1005.3.1

1005.4

1005.7

Section 1007 1007.2.1

§ 1005.3.1 states that stairs are to be sized based on the occupant load of the invidual story served by the stair. Thus the highest occupant load of any story served by a stair will determine the minimum size of the stair. This is based on observations of the time factor, along with their directional nature, in determining how people move through egress systems. The occupants of the floor below are assumed to exit that level before those behind them get to the same point in the egress system. § 1005.4 states that the capacity of the egress paths shall not decrease in exit capacity in the direction of egress travel. This corresponds to the watercourse analogy as well. This is further supported by § 1005.6, which requires that when egress paths merge, the capacity of the egress paths serves both tributary areas. Because exit doors typically swing in the direction of exit travel, doors from rooms will often swing into paths of egress travel, such as corridors. § 1005.7 requires that in such situations: • The door should project a maximum of 7” (178) into the required width when fully opened against the wall of the passage, and • The opening of the door should not reduce the required width by more than one-half. • Along narrow corridors, doors should be recessed. Minimum recess for a 36” (914) door would be: 36”– 7” = 29” (914 – 178 = 736) • Nonstructural provisions, such as trim and similar decorative features, can project into the required corridor width a maximum of 1 1/2” (38) on each side. Handrail projections are to be per § 1014.8. Accessible Means of Egress Buildings with four or more stories. In buildings where a required accessible floor is four or more stories above or below a level of exit discharge, at least one required accessible means of egress shall be an elevator complying with Section 1007.4.

1007.3 Enclosed Exit Stairways An enclosed exit stairway, to be considered part of an accessible means of egress, shall have a clear width of 48 inches minimum between handrails and shall either incorporate an area of refuge within an enlarged floor-level landing or shall be accessed from either an area of refuge complying with Section 1007.6 or a horizontal exit.

1008.1.1 Size of Doors Size of doors. The minimum width of each door opening shall be sufficient for the occupant load thereof and shall provide a clear width of not less than 32 inches. Clear openings of doorways with swinging doors shall be measured between the face of the door and the stop, with the door open 90 degrees. Where this section requires a minimum clear width of 32 inches and a door opening includes two door leaves without a mullion, one leaf shall provide a clear opening width of 32 inches. The maximum width of a swinging door leaf shall be 48 inches nominal.

“Common path of egress travel" is: that portion of exit access which the occupants are required to traverse before two separate and distinct paths of egress travel to two exits are available. Paths that merge are common paths of travel. Common paths of egress travel shall be included within the permitted travel distance. In no areas do the common paths of egress travel - when added to the distances between exits on any level - result in an overall travel distance which exceeds those permitted in Table 1015.1.

Chapter 11

Accessibility § 1103.1 states that the requirements for accessibility apply both to buildings and to the sites where they are located. The accessible route is 1103.1 typically considered to extend to the boundaries of the site. Every path of travel may not need to be accessible, but a readily located accessible route must be provided inside and outside of the building and on the site.

All units on a site shall be considered to determine the total number of units and the required number of Type A units. Type A units shall be dispersed among the various classes of units. § 1107.6.1.2 requires every dwelling unit to be a Type B dwelling unit in residential occupancies, 1107.6.1.2 such as Group R-2 and R-3 occupancies, where there are more than four dwelling units. See also the comment at left regarding I occupancies. Recreational facilities that serve Group R-2, R-3, 1110 and R-4 occupancies are to be accessible.

Comments

exception: requirements, and these exceptions are distributed among sections in other chapters of the code. The exceptions apply in general to low occupancy spaces and those where provision of access would be disproportionate to the utility of the space. exception:The only exception to this requirement is for a large site where elements are spread out along a vehicular access route that is not in itself accessible. This assumes that all people on the site are moving from one location to another by vehicle and that there is not a separate inaccessible pedestrian route for people without disabilities.

Window to wall ratio 60% at one long facade. 20% at the others. High Performance Envelope

Design Narrative: Our team select the second massing as our final scheme. The building depth of the more compact one will be very long and the central part can not gain any daylight. The less compact one is in confliction with our concept of a high-density urban community. The tower scheme is very compact and the depth is 40-50 feet so that daylight can cover most part of the room.

BUILDING SITE DIAGRAM ORIENTATION 1

BUILDING SITE DIAGRAM ORIENTATION 2

BUILDING SITE DIAGRAM ORIENTATION 3

The main orientation of our building is south/southeast so that most units can gain enough daylight by facing south. Through the calculation, we also find out that putting more windows along one long facade can save more energy.

The short building depth and floor to ceiling windows make it possible for all units to face south/southeast to gain equivalent daylight.

BUILDING SITE DIAGRAMS NATURAL VENTILATION

Northwest Operable Window

Design Narrative: The short building depth and floor to ceiling windows make it possible for all units to face south/southeast to gain equivalent daylight. Single corridor layout also guarantees direct access to sunlight without being blocked by other buildings. The balcony side is facing the south/south east while the corridor side is facing the north/northwest. Thus, the unit can enjoy morning and noon daylight rather than exposed to the afternoon west sunlight.

Southeast Balcony

NATURAL VENTILATION PLAN DIAGRAM Because of the short depth of the tower, most units facing the south/southcan have cross ventilation. (d/h = 50/12 <5)

NATURAL VENTILATION SECTION DIAGRAM Balcony area and floor to ceiling windows increase natural ventilation rate.

NATURAL VENTILATION ISOMETRIC Public space (void space) ventilation can help reduce the level of pollutants in “closed” corridor area.

All units have one side facing the street and one side facing public park; cross ventilation will be the main strategy. (d/h = 50/12 =4.16 <5). Big public space connects to corridors, and such void space ventilation can help reduce the level of pollutants in “closed” corridor area.

Green Roof

Schematic Design For the schematic design, we chosed 20’ by 20’ grid system for building structure so that each living unit is 20’ by 40’. Three structure options are concrete structure with two-way slab and beam, concrete structure with two-way waffle slab, and steel structure.

19” domes and 5” ribs create a 2’ module 3” to 4-1/2” slab depth; rule of thumb for total depth: span/24=10” square metal or fiberglass dome forms are available in 19” and 30”

Considering we have green roofs on the top and roof live load will be much heavier than regular roof. Concrete structure may be more reasonable for this superstructure.

There are three types of facades in this project based on diferent programs and plan layout. The fisrt one is on the bacony side of the living units. As the bacony is a triangle shape, the facade that faces to the bacony is composed of fixed glass, tilt window and glass sliding door. The solid area of the facade is covered with sandstone panels, which is a local material in Michigan. The percentage of glass in this facade is 75% and they are facing to south as well as north, which is intended to increase the sunlight into living room and bedroom. The second type of facade is located in the corridor side of the living units. It’s primary located on the west elevation of the highrise. The facade is basically a curtain wall system with 4’ by 4’ bluestone panels hanging on the outside of the glass. Both the stone panels and the solar control glazing function as shading elements. The third type of facade is store-front curtain wall system for all of the public space that includes sports court, restaurant, commercial and other types of community space.
