1 Project Assessment, Programming, Planning Flashcards
What does the ICC stand for?
International Code Council
What is the ADA
A national federal law (not a code or standard) that regulates removal of barriers for the physically disabled
ADA vs ICC A117.1
ADA is based on A117.1 but is not a code or standard. Designers must adhere to the ADA when designing facilities covered by the law
What is a model code?
a code that has been written by a group comprised of experts knowledgeable in the field w/o reference to any particular geographical area
What is the IBC
Primary model code
produced by ICC
What is ANSI
American National Standards Institute
standards approving group
What is ASTM?
organization that publishes thousands of test procedures that show how the test must be done
What is BOMA
Building Owners and Managers Association
produces standards detailing common methods of measuring spaces
ANSI BOMA Z65.1 - Legacy Method
may result in different load factors for each floor
uses separate R/U ratio (rentable area divided by usable area) for each floor
ANSI BOMA Z65.1 - Single Load Factor Method
uses same load factor for all floors
uses R/O ratio (net floor area divided by usable area) instead of the R/U ratio
What is an efficiency factor?
a mathematical ratio of one area to another
takes into account the required circulation per tenant and non-usable area required for partitions, columns etc.
Efficiency factors of different spaces
office - 0.75 retail - 0.75 bank - 0.70 restaurant - 0.70 hotel - 0.70 public library - 0.77 school - 0.60 apartment - 0.66 hospital - 0.54
What is rentable area?
tenants occupant area x load factor
to account for the shared portions of building
ANSI BOMA Z65.1 - partial floor
When office lease space only occupies a portion of a floor
if glass is >50% of wall area, occ. area is measured from inside of glass surface of exterior walls to finished inside surface of tenant side of corridor and from centerlines of demising walls
if glass is <50% of wall area, space is measured to inside surface of exterior wall
columns, recessed entries, and structural projections are ignored
ANSI BOMA Z65.1 - full floor
tenant area includes all space taken by the base building circulation, as well as elevator lobby
What is base building circulation
the minimum path on a multi-occupant floor necessary for access to and egress from occupant areas, elevators, stairs, restrooms, janitors closets, and similar areas
What are the two methods ANSI BOMA Z65.1 uses to determine rentable area?
The Legacy Method
Single Load Factor
4 energy categories that ID can reduce energy consumption
building commissioning, mechanical systems, electricity use, plumbing
What is building commissioning?
process of inspecting, testing, starting up, and adjusting building systems and then verifying and documenting that they are operating as intended and meet the design criteria of the contract docs
Ways ID can reduce energy with mechanical systems
design tenants HVAC system to conform to most stringent energy code
do not use mechanical system components for tenant spaces that include CFC-Refrigerants (mandatory for LEED)
Use displacement ventilation if possible (supply is at floor level)
Actions ID can take to reduce energy with electricity
reduce power required for lighting (task/ambient systems/daylight)
spec auto lighting controls
have elec engineer set up nonemergency lighting on timer for nonbusiness hours
specify daylight responsive controls
spec energy efficient appliances
spec sub metering equip. to measure and record energy uses within a space
Actions ID can take to reduce energy with plumbing
spec low flow fixtures
What are some indoor air contaminants?
Chemical: VOCs Inorganic Chemicals Tobacco smoke Biological: Mold pollen bacteria viruses
What three conditions are required for mold to grow?
moisture, a nutrient, and a temp from 40-100 degrees
Causes of poor indoor air quality
- chemical contaminants from indoor sources
- chemical contaminants from outdoor sources
- biological contaminants
- poor ventilation
Symptoms of poor indoor air quality
sick building syndrome
building-related illness
multiple chemical sensitivities
What is sick building syndrome
a condition in which building occupants experience a variety of health related symptoms that cannot be directly linked to any particular cause
What is Building related illness
a condition in which the health related symptom of a buildings occupants are identified and can be directly attributed to certain building contaminants
What is multiple chemical sensitivity
a condition brought on by exposure to VOCs or other chemicals
Strategies for maintaining good IAQ
Eliminate or reduce source of pollution
control ventilation
establish good maintenance
control occupant activity
What is adaptive reuse?
begins with reusing as much of the existing building stock as possible instead of constructing new buildings
Renewable Materials
Includes products typically made from plants that are harvested within a cycle of 10 years or less
Can get LEED credit for using rapidly renewable building materials and products for 5% of the total value of all building materials
