Sustainability Flashcards
The wastewater produced by toilets and urinals.
Blackwater
A broad philosophy and social movement that advocates to protect natural resources from pollution especially through political activism and education.
Environmentalism
The variety of life in particular habitat, often used as a measure of its health.
Biodiversity
Wastewater generated from dishwashing, bathing and laundry, which can be recycled for flushing toilets, landscape irrigation, etc.
Gray water
Any number of gases in the atmosphere, such as methane, carbon dioxide, etc…
Greenhouse gas
Natural energy resources such as solar, wind, tidal , etc…
Renewable energy
A bank of earth placed against one or more exterior walls of a bldg. as a protection against extremes in temperature.
Berm
A stack of black, water-filled drums placed on the inside of a window wall to absorb solar heat and then release it slowly into the interior of the building.
Drumwall
A massive exterior wall having vertical channels through which solar-heated air passes , serving as a heat reservoir for short time periods and radiation to interior wall and spaces.
Murocaust
A glass fronted exterior masonry wall that absorbs heat for radiation into the interior of a building, usually after a time lag of several hours.
Trombe wall
A glass enclosed porch ,room, or gallery used for sunbathing or for therapeutic exposure to sunlight.
Solarium
A glass enclosed porch or room oriented to admit large amounts of sunlight. Also called sun parlor, sun porch.
Sunroom
A method of passive, nonmechanical heat exchange based on the natural convection of a heatd liciuid expanding and rising and being replaced in the loop by cooler returning by cavity.
Thermal siphon
The outside temperature at which the sum of solar and internal heat gains balances the heat losses through a building’s envelope, ventilation, and infiltration. Below the balance point temperature, supplementary heat Is required to maintain the desired Indoor temperature.
Balance point temperature
Techhnologies or techniques, such as such a natural ventilation, evaporative cooling, or high thermal mass, used to cool buildings without consuming power.
Passive cooling
The replacement of the volume of air contained within a room with an equivalent volume of fresh air within a given period of.time. The term air changes-per-hour is often used to specify ventilation standards.
Air change
Any of yarious technologies or techniques that uses nonmechanical, nonelectrical means, such as radiation, conduction, and natural convection, to distribute heat and daylight.
Passive System
A solar-heating system using a building’s design and construction and the natural flow of heat to collect, store, and distribute solar energy, with minimal use of fans or pumps.
Passive solar-heating
An opening in a wall serving as an outlet for air, smokes, fumes or the like.
Vent
The process of ventilating a space by the natural movement of air.
Natural ventilation
The circulation of air through open windows or other openings on opposite sides of a room.
Cross ventilation
A louvered opening or motor-driven fan for replacing stagnant air with fresh air.
Ventilator
A wind or motor driven fan for assisting the natural air flow through attic space.
Attic ventilator
A whole house ventilating system consisting of a fan and duct system that introduces fresh air into one or more rooms of a house while air leaks out through holes in the building envelope, exhaust fan ducts and any window or wall vents.
A. Supply Ventilation System
B. Balanced Ventilation System
C. Energy- Recovery Ventilation System
D. Exhaust Ventilation System
A.
A whole house ventilating system suitable for cold climates , consisting usually of a single fan that extracts indoor air from house while make up air infiltrates through leaks in the building shell through adjustable, passive vents.
A. Supply Ventilation System
B. Balanced Ventilation System
C. Energy- Recovery Ventilation System
D. Exhaust Ventilation System
D.
A motor driven fan that pulls fresh air in from the open windows and exhaust it through attic and roof vents.
Whole house fan
A device that rotates an array of blades or vanes about an axis in order to produce a current of air.
Fan
A fan for ventilating an interior space by drawing air from the interior and expelling it out side.
Exhaust fan
A fan that receives air along its axis and discharges it radially.
Centrifugal fan
