What are the environmental impacts of a building? In the United States - CORRECT
ANSWER- ✔✔** 14% of potable water consumption**
30% of waste output
40% of raw material use
38% carbon dioxide emissions
24-50% energy use
72% electricity consumption
what are the effects of conventional practices on human health, the environment and the
economy? - CORRECT ANSWER- ✔✔- clearing land destroys wildlife
- extracting/manufacturing/transporting materials can cause pollution and emissions
- building operations require large amounts of energy and water & produce waste
- transportation to and from the building has harmful effects
what percentage does energy decrease from a typical building to a green building? -
CORRECT ANSWER- ✔✔energy is 24% lower in green buildings that in typical buildings
,how much energy consumption -- building associated transportation vs operations -
CORRECT ANSWER- ✔✔30% more energy is expended commuting than is consumed
through heating, cooling, lighting etc-- even in modern energy code its more than 50%
commissioning - CORRECT ANSWER- ✔✔a process of testing and checking all equipment
and systems within the facility at the end of a project to assure proper functioning and
operation-- all assemblies are planned. designed installed and tested to meet owners project
requirements
Retrocommissioning - CORRECT ANSWER- ✔✔A tune-up that identifies inefficiencies and
restores high levels of performance ** existing building**
Systems Thinking - CORRECT ANSWER- ✔✔an assemblage of parts that interact in a series
of relationships to form a complex whole , serving particular funtions or purposes
open system - CORRECT ANSWER- ✔✔materials and resources are brought in from the
outside, released from the system as a form of waste
closed system - CORRECT ANSWER- ✔✔one where quantity or series of quantities cannot
enter or leave the system (more sustainable)
feedback loop - CORRECT ANSWER- ✔✔explain how systems work
positive feedback loop - CORRECT ANSWER- ✔✔a feedback loop in which change in a
system is amplified (heat island effect)
heat island effect - CORRECT ANSWER- ✔✔Warmer temps are experienced in urban
landscapes due to solar energy retention on constructed surfaces. Principal surfaces include
streets, sidewalks, parkings lots and bldgs.
negative feedback loop - CORRECT ANSWER- ✔✔A feedback loop in which a system
responds to a change by returning to its original state, or by decreasing the rate at which the
change is occurring (prius effect)
, Prius effect - CORRECT ANSWER- ✔✔Delivering real-time energy information in a
convenient way by installing meters where operators can act on the information and make
changes to use energy more efficiently.
leverage point - CORRECT ANSWER- ✔✔a point in a system in which a small change can
yield large results
**providing building occupants real time information through metering is a leverage point to
alter behavior**
Life Cycle Assessment (LCA) - CORRECT ANSWER- ✔✔A technique to assess
environmental impacts associated with all the stages of a product's life, i.e., from raw
material extraction through materials processing, manufacture, distribution, use, repair and
maintenance, and disposal or recycling---used to identify social impacts of a product's life
cycle as well.
Life Cycle Costing (LCC) - CORRECT ANSWER- ✔✔evaluation of the total cost of a
building or product over its useful life, including initial, maintenance, repair and replacement
costs as well as savings. LCC evaluates economic performance.
** evaluate initial price/acquisition/construction, fuel, maintenance/repair, replacement etc**
Integrative Process - CORRECT ANSWER- ✔✔A design process in which multidisciplinary
teams collaborate to meet sustainable design objectives from the inception of a project to its
completion-- using mutual advantages to achieve high levels of performance, comfort and
environmental benefits
1. discovery / predesign
2. design and construction
3. occupancy, operations, performance feedback
design synergy examples - CORRECT ANSWER- ✔✔-- designing landscapes with native
species to reduce water consumption and provide habitat for local species
-- composting improves soil quality and reduces GHGs related to trash transportation
Integrated Project Delivery (IPD) - CORRECT ANSWER- ✔✔A collaborative approach to
designing, fabricating, and constructing buildings where the architect, technical consultants,
and contractors work as one team to reduce delivery times, reduce costs, reduce wastes, and
eliminate litigation.
