Sprinklers
ANALYSIS daylighting & systems
Day Lighting
- Small building energy consumption tends to be driven primarily by heating and cooling loads associated with thermal exchange through the building’s exterior skin. Thus, in cold climates, energy consumption is dominated by the need to replace hat lost through the walls and roof during the cold months. In warmer regions, like Texas, energy consumption is driven by the removal of heat gained through the exterior envelope during the warm months. - Daylight illumination can also contribute to reduced cooling loads in warm climates. Indirect light from the north sky or from well-shaded southern exposures is an excellent source of illumination with low heat content. Direct sunlight can be reflected off exterior surfaces before it is admitted into a structure, thereby leaving a significant portion of its heat content outside the building.
- A sprinkler system is required for any stories or basement exceeding 1500 sq ft if the area doesn’t have openings to the outdoors. - Our building will not require sprinklers.

Structural Steel Beams
- Steel beams can be used as combustible and noncombustible construction. Fire-resistance ratings of as high as 4 hours are achievable with applied fireproofing or an appropriately fireresistive ceiling. Some building codes also allow reduced fire protection or exposed steel for roof structures that are 15 to 25ft or more about the floor.
- Widths of beams range from approximately 1/3rd to ½ the depth of the member

Structural Steel Tube Columns - Standard shapes for structural hollow steel sections include square tubes, rectangular tubes, and round pipes. Compared to wide flange sections, they are more resistant to bulking forces, making them a good choice for columns or compressive members in all types of steel systems. They are employed as columns in long span steel structures for their greater efficiency, and because they are available in lighter weights than other standard shapes, they are frequently used in one or two-story steel structures as well. - The simple profiles and clean appearance of hollow steel sections make them popular for use where the steel remains visible in the finished structure, or the structure is exposed to the elements. Tubes or pipes are generally available in whole-inch sizes up to 6 or 8 in. and in even-inch increments up to 12 to 16 in. - The Architect’s Studio Companion; Rules of Thumb for Preliminary Design, Allen & Iano
TEM AL SYS
SEC
- With group B with more than on occupancy load exceeding 49 there needs to be 2 exits. - The ways out must be separated by a distance equal to not less than one-half the diagonal measured of the room, space, or floor. If the building is sprinklered, the distance may be reduced to one-third the diagonal measure of the space. - Maximum travel distance in an unsprinklered building is 200’ in a sprnklered its 300’. - Maximum common path of egress travel: 75’ unsprinklered 100’ sprinklered - Minimum length of dead-end corridor: 20’ unsprinklered 50’ sprinklered - Door width: Min: 32” net clear Max: 48” nominal - Minimum clear corridor width 44” for 49+ occupants 36” serving 49 or fewer - Minimum stair width 44” for 49+ occupants 36” serving 49 or fewer
- Exposed hollow steel columns may be used in both Unprotected Noncombustible and Unprotected Combustible Construction. For Protected Construction Types, fire-resistance ratings up to 3 hours for very light sections and 4 hours for heavier ones are achievable with any number of fireproofing materials applied in thicknesses of 2 to 4 in per side. - Ratings of 3 hours can also be achieved with intumescent coatings, or with specially designed hollow sections that are then filled with concrete. - The Architect’s Studio Companion; Rules of Thumb for Preliminary Design, Allen & Iano
- Our building type allows for no fire resitance requirements.
Steel Roof Decking
Parking
- Steel roof decking may have a site cast concrete or gypsum topping or may be covered directly with a variety of board or roofing products. Many proprietary metal roof decking systems, with a wide variety of performance characteristics are available.
- “There should be roughly 50 parking spots and we wouldn’t expect to have them all in use very often but with staff and members plus volunteers we just need to be sure and have enough in case...”
- We will use steel decking because it is a light cost effective roofing choice and it allows for easy attachment of other materials as well as our solar panels. The sizing will be 3” deep to allow for spans up to 16’. - The Architect’s Studio Companion; Rules of Thumb for Preliminary Design, Allen & Iano

Heating and Cooling; Ground Source Heat Pump
- In winter a geothermal heat pump collects the Earth's natural heat through a series of pipes, called a loop, installed below the surface of the ground. Fluid circulates through the loop and carries the heat to the building. An electrically driven compressor and a heat exchanger concentrate the Earth's energy and release it inside the home at a higher temperature. Ductwork distributes the heat to different rooms. In summer, the process is reversed.
