PA Mix Flashcards
How do you calculate a building’s efficiency?
A building’s efficiency is the net area divided by the gross area. Buildings that have a lot of circulation and support areas are less efficient than buildings that are almost entirely usable, such as a warehouse.
What is a Xeriscape style of Landscaping?
Xeriscape is a type of low water-consuming landscaping, popular in arid regions. Xeriscape landscapes use native plantings and rock or gravel and do not use irrigation.
What is a Naturalistic style of Landscaping?
Naturalistic landscapes are informal and draw their aesthetic inspiration from nature such as forests and meadows. A naturalistic landscape attempts to look like it was not designed, but is part of the natural landscape.
What is a Formal style of landscaping?
Formal landscapes have clear structure and strong geometric forms. They are also often symmetrical and have eye-catching elements such as statues or fountains at the end of long axial pathways.
What three things determine the maximum height of a building?
Zoning Regulations
-limit building height by setting maximum height limits and establishing floor area ratios (FAR).
Occupancy group
-the International Building Code specifies maximum heights based on the type of construction and occupancy group.
Type of Construction
-the International Building Code specifies maximum heights based on the type of construction and occupancy group.
NOT:
occupancy group or proximity to fire station
How should the architect depict compliance with setbacks on a drawing?
Show the property line as a dashed line, show the proper setbacks from the property line and dimension from the setbacks to the building face. The property line should be shown on site plans. Dimensioning to the building face will clearly show if setback distances are met.
What is a “Transfer Beam”?
Transfer beam is a horizontal structure that transfers heavy gravity loads from the above structural elements to the below structures. These are beam elements that are mainly employed in the design of high-rise building structures. They are designed to take up load more than what a normal beam is designed for.
Think “concrete header”.
True or False?
Passive solar systems store electricity?
False
What is a benefit of passive solar heating that the architect can discuss with the client?
Low maintenance costs
-there are generally low maintenance requirements for passive solar heating systems.
What is typically included in a boundary survey?
Easements and right-of-ways
-a boundary survey shows a property’s boundaries, easements, setbacks, zoning, and any improvements such as buildings, walls, or fencing.
note: Location and characteristics of utilities and spot elevations are found on a topographic survey. Topographic surveys are often conducted along with boundary surveys.
Which steps should be taken to minimize slope destabilization?
Use alternatives to septic systems
Comply with local grading ordinances regarding the use of retaining walls for steep hill cuts
Review local landslide hazard maps and landslide reduction regulations
Utilize native plantings that require little irrigation
What ratio of street width to building height prioritizes pedestrians?
1.5 : 1
Just a little wider- not too wide or it encourages faster vehicular speeds.
Vegetation makes the street pedestrian friendly.
Multiple types of users on street encourage social interaction.
How will the architect and client use this construction budget?
To set cost guidelines for their work
-the budget serves as a guide, establishing parameters for the project costs. It keeps the architect from spending too much in the wrong place and helps them to meet the project goals.
Budgets are not hard numbers and often fluctuate.
What does a storm drain do?
-is designed to drain excess rain and ground water from impervious surfaces such as paved streets, car parks, parking lots, footpaths, sidewalks, and roofs.
This is not an effective technique for reducing runoff volume and improving stormwater quality.
True or False?
A privately owned facility with three units would not fall under the requirement to have ADA accessibility as per the Housing and Urban Development (HUD).
True
Per 2010 ADA Standards - Section 233, residential structures having four or more multi-family dwelling units, regardless of whether they are privately owned or federally assisted, include certain features of accessible and adaptable design according to guidelines established by the U.S. Department of Housing and Urban Development (HUD). A privately owned facility with three units would not fall under this requirement.
What is the primary function of a vegetated roof?
Stormwater management
-vegetated roof covers or “green roofs” provide an important strategy for the management of stormwater. They can reduce runoff on a site by 50 percent.
What is a Control Joint used for?
Control joints are used to regulate cracking in concrete pours, such as slabs and walls. They limit cracking from thermal movement, curing shrinkage, etc.
Where will the maximum bending moment at an exterior balcony be?
The maximum bending moment is where the balcony intersects the wall. The bending moment occurs here because the wall is a rigid connection point for the balcony. It provides an upward force on that point, which is countered by a downward force of the balcony load.
Name some of the characteristics of a successful transit-oriented development?
Diverse housing types
-a mix of housing types ensures population density for the development.
Varied housing prices
-a variety of housing prices, including affordable housing, should be planned.
Mixed-use functions
-they benefit this type of development by providing residential functions adjacent to commercial and office functions, increasing the vitality of the community. Mixed-use also provides opportunities for shared parking.
Increased bicycle facilities
-facilities for bicycles should be increased, including dedicated bicycle paths and bicycle parking.
Preservation
-the act or process of applying measures necessary to sustain the existing form, integrity, and materials of a historic property. Work, including preliminary measures to protect and stabilize the property, generally focuses upon the ongoing maintenance and repair of historic materials and features rather than extensive replacement and new construction. The limited and sensitive upgrading of mechanical, electrical, and plumbing systems and other code-required work to make properties functional is appropriate within a preservation project.”
Preservation is the appropriate choice for the scenarios such as, “The stone cornice of a historic hotel is patched and repaired,” and, “An 1890 train station will be reused as a light rail station but will largely retain its original look and feel.”
Rehabilitation
-the act or process of making possible a compatible use for a property through repair, alterations, and additions while preserving those portions or features which convey its historical, cultural, or architectural values.”
Rehabilitation is the appropriate choice for the scenario, “An old theater is being repurposed as a bookstore and coffee shop.”
Restoration
-the act or process of accurately depicting the form, features, and character of a property as it appeared at a particular period of time by means of the removal of features from other periods in its history and reconstruction of missing features from the restoration period.”
Reconstruction
-the act or process of depicting, by means of new construction, the form, features, and detailing of a non-surviving site, landscape, building, structure, or object for the purpose of replicating its appearance at a specific period of time and in its historic location.”
Reconstruction is the appropriate choice for the scenario, “A badly deteriorated native dwelling is carefully studied and missing parts are replaced with great accuracy.”
True or False
Building on greenfield sites promote sustainability.
False
What is the approximate percentage of the total area that can be developed after accounting for the minimum amount of space needed for infastrcuture when planning a residential neighborhood?
70 - 90%
-Infrastructure is a major part of residential neighborhood planning. Infrastructure commonly includes roads, utility easements and other rights-of-way, as well as accommodations for public structures. Infrastructure may use 10 - 30% of a residential neighborhood’s gross land area.
What is the primary reason a city has for controlling the floor area ratio (FAR) of a site?
To control density
-the FAR (floor area ratio) controls the square footage of the building being developed relative to the size of the site. Therefore, if a city wants to create density, it would allow a high FAR, which would enable developers to build more area and/or floors.
Name 4 actions that comply with the best practices for maintaining defensible space (measures to prevent forest fires)?
Store firewood uphill from the building.
Reduce forest density within 100 feet from the building.
Do not use wood chip mulch directly adjacent to the building.
Extend defensible space further on the downhill side of the building (Fires spread vertically and travels uphill, therefore, a larger defensible space is required on the downhill side of the building).
Name three benefits from an urban in-fill project?
Neighborhood revitalization
-taking use of vacant and underused land increases population density and neighborhood continuity. A critical mass of people is required to support retail, an amenity the existing community can utilize.
Creation of mixed-use development
-mixed-use development creates a presence of people at all times of the day, which increases public safety and community connection.
Promotion of sustainability strategies
-there is an opportunity to promote sustainable strategies, including utilization of existing infrastructure and community amenities. Public transit is also more viable in densely populated areas.
NOT:
parking
property values (promotes gentrification)
True or False?
Utilizing brownfield sites is often seen as a positive and sustainable practice, regardless of strategy used.
True
What is the best HVAC system to use when you have need multiple unit individual controls (i.e.-motel)?
Local air-to-air heat pumps
-this is the best option that will allow the individual user high autonomy of control for each unit. It is well-suited for this system where rooms tend to be located on the perimeter and climate can be adjusted to account for the difference in exposure promoted by orientation of the structure. The system is relatively economical because the installation costs would be lower than a complete HVAC refrigerant system with the associated equipment and ductwork. The unit is also more energy-efficient than the local unitary air conditioning unit.
Which soil type is the least susceptible to liquefaction during a seismic event?
Clay
-liquefaction is when a soil behaves like a liquid, such as when seismic “S” waves cause vibrations during earthquakes. Loose and uncompacted granular soils such as sand and sandy (non-plastic) silts are the most susceptible to liquefaction. During liquefaction, soils lose their shear strength. A clay content of 15% or more is considered adequate protection from liquefaction.
Name an analysis that will assist in designing building systems to meet performance goals?
Model-based analysis (BIM)
-model-based analysis, which can include energy modeling, building performance modeling, life cycle cost analysis, or other types of simulation, is a process that uses the three-dimensional model of the building to predict various aspects of performance while still in the design phase. Some combination of these analyses should be performed by the architect or appropriate consultant to determine if the design will be likely to meet the client’s goals. After construction, a commissioning agent or other authority will need to verify ongoing performance of the building and its systems through testing or observation of the actual facility.
What is the simplest form of cost estimation?
Comparison
-this is a cost estimate based on the comparison of a similar building, adjusted for location and inflation.
What type of cost estimation is completed at the schematic design phase?
Gross square footage
-this is a cost estimate based on the square footage of a building and is slightly more detailed than a comparison estimate.
What type of grain patters will show if wood is quarter sawn?
Even grain patters. Growth rings will run parallel to board edges. (thin straight lines)
What type of grain patters will show if wood is plain sawn?
Noticeable grain patterns
Which strategy should the architect propose in order to reduce the heat island effects in a project?
Incorporate a rooftop garden
-rooftop gardens reduce the heat island effect while also providing outdoor space for building residents.
Name three conditions that could lead to the decision to phase a project?
The initial budget is limited
-when the initial budget is limited, a phased schedule can provide extra time to obtain money for additional phases.
The client’s functional needs are expected to grow
-when functional needs are expected to grow, phasing allows the client to provide more space as needed, instead of creating a large building upfront, which can be expensive and possibly underutilized at first.
Money for the project will become available over time
-when money will become available over a period of time, phasing can be useful because it allows an owner to build as the funds become available to do so.
An architect is working on a small development where the developer would like to minimize greenhouse gas emissions.
Which energy source will help them meet this goal?
Geothermal
-geothermal systems emit no greenhouse gases during operation. According to the U.S. Office of Energy Efficiency and Renewable Energy, their life cycle greenhouse gas (GHG) emissions are four times less than solar PV emissions and up to 20 times less than natural gas emissions.
What is a Parti diagram in architecture?
A quick concept sketch. A parti diagram is a rough drawing, doodle, or diagram used early in the schematic design process to represent a design concept. The classic “napkin sketch”. Note that a design parti, is not necessarily a diagram. The word is from the French phrase parti pris, meaning to make a decision.
Name and describe 4 types of Parti diagram styles?
Bauhaus or International Style; characterized functional design and geometric form.
Beaux-Arts; characterized by symmetrical, harmonious designs.
Panopticon; characterized by a radial system, all parts of the floorplan are visible from a central point.
Gothic; characterized by tall heights, long corridors, and Christian symbolism (floorplan in the shape of a Christian cross)
note:
lighter and bolder lines define hierarchy
Name a soil type that would be the best for a building’s foundation?
(GW) Well Graded Gravel
-GW has excellent shear strength, negligible compressibility, and excellent workability. GW soils are preferred for subgrade and base conditions.
What is the principal benefit of using a DOAS (dedicated outdoor air system) system?
The supply air can be comprised of 100% fresh outside air
-A DOAS system is often used on projects with high sustainable performance criteria. The ability to provide 100% fresh outside air reduces energy dependence because the return air system is powered and used far less frequently than in a conventional HVAC system.
Name four environmental mitigation solutions to help clean up a brownfield site?
Incineration
-Incineration is controlled burning of soil or solids to convert, degrade, or oxidize contaminants. It may be done on or off site.
Dechlorination
-Dechlorination is chemical treatment to remove chlorine atoms bonded to hazardous chemicals. Hydrogen or hydroxide ions are used to detoxify materials.
Soil vapor extraction
-Soil vapor extraction is used to remove VOCs from soil through the use of vapor extraction wells. It is sometimes used in conjunction with air injection systems. Contaminants are volatilized and flushed into the air for treatment.
Air sparging
-Air sparging is the injection of air into groundwater to flush volatile contaminants, which are collected and treated by the soil vapor extraction process.
Under the Secretary of the Interior’s Standards for Rehabilitation, what should be done to mistakes or erroneous additions that have taken place over the history of a building?
Protect the elements in place as they are now part of the building and should be recognized for their historic value.
