Q

Module 1:

What is the definition of Architectural Programming?

A

Architectural Programming refers to an important early part of the design process, where you identify and organize the architectural, functional, aesthetic, operational, and budgetary needs of your client.

This information (often put into a written document called a “Program”) is then used to help guide your decision making process in the design of the building.

If done correctly, Programming can ease the design process and improve the final result.

Name five phases that are preformed during programming

A
  1. Gathering Data: site surveys, existing conditions, desired use, building type, applicable building codes, zoning requirements, budget, schedule, and project team info are all collected and organized.
  2. Establishing Goals: the Architect interviews the Owner to identify the primary design goals and potential issues.
  3. Mapping Functions: functional and spatial requirements are listed with their approx size, important adjacencies and relationships to one another.
  4. Setting Priorities: the uses and functions are listed in order of importance based on the budget, including where the attention and budget should be spent.
  5. Researching Requirements: detailed technical requirements are collected for any required equipment, systems, operations, and performance.

A

less than 4% slope is considered flat and suitable for all activities

4%-10% moderate and requires some effort to climb or descend

10%-50% steep and suitable only for limited activity

50% + very steep and is subject to soil erosion or collapse

28
Q

Module 1:

What is the max slope allowed for an accessible ramp?

A

Handicapped ramp slopes must be a 1:12 slope (1ft rise or ever 12ft run)

1/12(100) = 8.3% slope

29
Q

Module 1:

45 Degrees translates to what percentage slope?

A

100% slope as rise over run is 1 to 1 or 1/1

30
Q

Module 1:

Why is solar orientation important when layout out a site design?

A

the more perpendicular the sun’s rays are to the site, the greater amount of solar radiation received.

important to note the amount of solar radiation received in order to design a building that maintains a consistent internal temperature.

31
Q

Module 1:

What factors of sun radiation should be taken into consideration when designing a site?

A

Time of day - how much sun is received on site in the morning compared to the afternoon

Azimuth - angle btw the sun and the horizon. summer sun has a larger azimuth that winter sun

Duration of Sun Exposure - sites in the norther hemisphere have more hours of sunlight in the summer than in the winter

Slope of Site - ground slope affects the amount of solar energy the site receives

32
Q

Module 1:

Describe the 5 basic fundamentals of physics that affect internal building comfort

A

Hot Air Rises - placing vents or windows in the correct location can help create cooling breezes

High Summer Sun - well positioned overhangs can shade the home and keep it cooler in the summer

Low Winter Sun - sunlight passes under any overhangs to reach into home and keep it warm

Thermal Mass - heavy mass materials (i.e. concrete, stone, brick, water) store heat and cold. when temp changes these materials release the stored temp back into the air

Insulation - well insulated building is req’d in order to hold in the interior temp and keep out the outside one

33
Q

Module 1:

What is a water table?

A

level of ground water below the surface of the ground

34
Q

Module 1:

How does the level of the water table on the site affect the design of the foundation?

A

if water table is less than 6ft below the surface, this is considered high and will limit foundation design

a mat slab or pile foundation may be necessary in order to evenly distribute the loads of the building on site

35
Q

Module 1:

What conditions could occur if a high water table is found in a cold climate?

A

high water tables in cold climates are especially problematic since water expands as it freezes

wrong type of foundation could crack or settle if the water table freezes and pushes it upward

36
Q

Module 1:

Define indigenous materials

A

locally found materials, don’t require transportation or import

most sites contain materials and resources that could potentially be used in the building

37
Q

Module 1:

What considerations should be given for exterior building materials?

A

exterior materials must withstand the elements

durable materials should be selected

local conditions should help determine the appropriate materials

38
Q

Module 1:

What is R-Value?

A

Insulation is measured in R-Value. the higher the R-value, the more insulation value the material has.

Materials like wood and siding have a small R-value, so high R-value insulating material is added into the wall assembly

39
Q

Module 1:

How does R- Value differ from U-Value?

A

U-Value = insulating value of windows

1/R-Value

Inverse of R-value - lower the u-value, the more insulation value it has

40
Q

Module 1:

Describe thermal mass and its importance to building design.

A

thermal mass = ability of a material to store temperature
ability of a material to absorb and store temperature

these materials take a long time to heat up and cool down, use high thermal mass materials to keep building temperature regular and consistent.

41
Q

Module 1:

Define Microclimate

A

microclimate = specific local conditions of the site

affected by vegetation, elevation, slope, water, wind, solar exposure, and man-made structures

42
Q

Module 1:

What climatic considerations should be evaluated during site design?

A

Temperature - comfort zone ranges between 63-71 degrees in winter and 66-75 degrees in summer

Humidity - comfort zone ranges between 30%-60% relative humidity

Solar Radiation - lack of natural lighting in winter can cause depression

Air movement - breezes promote evaporation thus maintaining consistent humidity levels

Air pollution - natural weather patterns can magnify the effects of man-made pollution

43
Q

Module 1:

Define Macroclimate

A

general climate of the overall region

44
Q

Module 1:

What are four site conditions that can affect the microclimate of a site?

A

Site Latitude - areas closer to the equator are warmer than those further away

Site Elevation - height above sea level affects rain and show fall as well as temperature

Prevailing Winds - depending on the location, winds can impact air temperature

Proximity to water - bodies of water provide humidity and can help maintain site temperature

Proximity to mountains - mountains direct prevailing winds to rise, which cools them and forms clouds

Topography - steep sloping sites can increase wind velocity thus decreasing site temperature

45
Q

Module 1:

Describe the four different climatic zones found in the US.

A

Cool Zone - Northern states

Temperate Zone - West Coast

Arid Zone - Midwestern and desert states

Tropical Zone - Southern states, especially near the Gulf

46
Q

Module 1:

What is the difference between a macroclimate and a microclimate?

A

Macroclimate - climate of a region (i.e. county or area)

Microclimate - climate of a particular site.
affected by bodies of water, ground slope, and solar radiation (north facing sites have less sun than south facing in the Northern Hemisphere)

47
Q

Module 1:

What site elements can be studied to determine the effect of the microclimate on the site?

A
  • location of plants and bodies of water
  • amount and location of sun exposure
  • prevailing wind patterns
  • ground surface coverage
48
Q

Module 1:

Define Albedo

A

measure of reflectivity of a material

ex. snow has a high albedo
grass has a low albedo

49
Q

Module 1:

Define conductivity

A

material’s ability to absorb light

ex. grassy areas - low albedo levels and high conductivity
paved areas have high albedo and low conductivity thus are often warmer than grassy areas

50
Q

Module 1:

Describe albedo and conductivity in relation to site elements.

A

albedo: radiant energy that is reflected by a surface where 0 is a flat brick surface that absorbs heat and 1 is a mirror
conductivity: rate at which heat passes through a material. Metals have high conductivity and soils/sand have a low one

51
Q

Module 1:

What is the best way to provide internal comfort in a building during a hot, summer day?

A

exterior: large overhangs to shade house from southern and western sun for most of the day
interior: thick concrete wall to absorb heat

52
Q

Module 1:
How is a space heated at night during the winter if it contains thick concrete walls and floors and has large windows facing south?

A

low winter sun warms the south side of the house all day. stone or concrete floors store up the heat. hot air is allowed to build up by the ceiling.

stored heat in the floor and walls is released during the night to keep the house comfortable

53
Q

Module 1:

How does proper building siting affect the views for a project?

A

buildings can be sited to create an axis to draw your eyes toward the view and enclose the outdoor space.

undesirable views can be avoided by locating service or utility spaces to face or block them

54
Q

Module 1:

What are the three primary reasons for landscape design?

A
  1. Recreation
  2. Circulation
  3. Comfort
55
Q

Module 1: Define a deciduous tree and name three species that fall under this category.

A

full with leaves through the spring and summer, providing shade. leaves fall in Autumn and expose bare branches through the winter allowing sun to pass into a building.

Decidious species: maple, elms, oaks, and sycamores

56
Q

Module 1:

Define a conifer and give 2 examples of this type of tree

A

needle like evergreens that do not shed leaves
year-round wind breakers or privacy screens

Conifer species: pines (spruce and firs)

57
Q

Module 1:

What purpose do deciduous trees serve best on a project?

A

best choice when a site requires shade in the summer and heat from the sun in the winter

58
Q

Module 1:
Your project program specifies that the site must be protected from cold winter winds. what type of tree would be best suited for this condition?

A

conifer trees

excellent wind breakers because they retain their dense needle filled branches year-round

59
Q

Module 1:

How does “smart landscaping” help act as a natural heat buffer on a site?

A
  • trees can help screen and direct winds on a site
  • trees and vegetation absorb sunlight and add humidity to the air
  • planted areas are cooler during hot summer days.
60
Q
