An escalator is a moving staircase, powered by an electric motor, that transports people between floors along a continuous loop of linked steps mounted on a motorized chain, widely used in locations with high pedestrian volume such as shopping centers, transit stations, and airports where continuous passenger flow matters more than the flexibility an elevator
A moving staircase powered by an electric motor that transports people continuously between floors.
A facade is the exterior face of a building, most often referring specifically to its principal or most architecturally significant side, typically the one facing a street or public space. Far more than a decorative skin, a facade performs real structural and environmental work, carrying or supporting cladding loads, managing the flow of heat, air,
The exterior face of a building, typically its principal or most architecturally significant side.
A fire protection system is the combination of detection, alarm, suppression, and passive design features built into a structure to detect a fire early, alert occupants, limit its spread, and in many cases extinguish it automatically before firefighters arrive. Fire protection engineering treats these elements as a layered, redundant system rather than relying on any
The combination of detection, alarm, suppression, and passive design features built into a structure to limit fire damage and protect occupants.
Formwork is the temporary mold, typically built from wood, steel, or engineered panel systems, that holds freshly placed concrete in its intended shape until the concrete cures and gains enough strength to support itself. Because concrete is placed as a wet, flowable material, formwork is essential to nearly all cast-in-place concrete construction, shaping everything from
The temporary mold that holds freshly placed concrete in shape until it cures and gains self-supporting strength.
Gentrification is a process of neighborhood change in which rising property values, rents, and investment attract wealthier residents and businesses to a previously lower-income or disinvested urban area, often displacing longtime residents who can no longer afford to live there. The term, coined by sociologist Ruth Glass in 1964 to describe changes she observed in
A process of neighborhood change in which rising investment and property values attract wealthier residents, often displacing lower-income residents.
A geothermal heat pump, also called a ground-source heat pump, is a heating and cooling system that uses the relatively stable temperature of the ground or groundwater, typically far more consistent year-round than outdoor air temperature, as a heat source in winter and a heat sink in summer, transferring heat between a building and the
A heating and cooling system using stable underground temperatures as a heat source and sink via a buried ground loop.
A green roof is a roof surface partially or completely covered with growing vegetation planted over a waterproofing membrane, rather than finished with conventional materials such as asphalt shingles, metal, or bare membrane. Green roofs range from thin, lightweight extensive systems planted with low-maintenance groundcover such as sedum, requiring minimal soil depth and little ongoing
A roof surface partially or completely covered with vegetation planted over a waterproofing membrane.
HVAC, an acronym for heating, ventilation, and air conditioning, refers to the combined systems that control a building’s indoor temperature, humidity, and air quality. Modern HVAC systems address three related but distinct needs: heating interior spaces during cold weather, cooling them during warm weather, and continuously supplying fresh outdoor air while removing stale indoor air,
The combined heating, ventilation, and air conditioning systems that control a building's indoor temperature, humidity, and air quality.
Lean construction is a project management philosophy and set of practices that applies principles originally developed in lean manufacturing, most notably the Toyota Production System, to construction, with the central goal of maximizing value delivered to the owner while systematically reducing waste in the form of unnecessary motion, waiting time, rework, and resources that do
A project management philosophy applying lean manufacturing principles to reduce waste and improve flow in construction.
Lighting design is the discipline of planning how artificial and natural light will illuminate a space, balancing functional visibility requirements with aesthetic, psychological, and energy considerations to support the activities that will take place within a given environment. Lighting designers work across architecture, interior design, theater, and other fields, applying knowledge of light quality, fixture
The discipline of planning artificial and natural light to support the functional and aesthetic needs of a space.
