A moment frame in structural design is a building system that resists lateral loads from wind and earthquakes through rigid connections between beams and columns. Instead of using diagonal braces or walls, the joints themselves carry bending moments and shear, letting the frame bend without collapsing while keeping floor plans...
HVAC stands for heating, ventilation, and air conditioning, the building system that controls indoor temperature, air quality, and humidity. For designers, HVAC shapes ceiling heights, shaft locations, and facade openings. Understanding it early lets you coordinate space and aesthetics instead of fixing conflicts after the layout is fixed. Most design...
A heat pump works in a building by moving heat instead of creating it. Using a refrigerant cycle driven by an electric compressor, it pulls thermal energy from the outside air, ground, or water and delivers it indoors for heating. In summer the cycle reverses, pushing indoor heat outside to...
Radiant floor heating is a system that warms a space by circulating heat through the floor itself, using either water-filled tubing (hydronic) or electric heating elements installed beneath the surface. Heat rises evenly across the room instead of blowing from vents, which keeps temperatures steady and removes the cold spots...
Natural vs mechanical ventilation comes down to how a building moves fresh air through its spaces. Natural ventilation uses pressure differences from wind and temperature to drive airflow through openings, while mechanical ventilation uses fans and ducts to control air volume, filtration, and heat recovery regardless of outdoor conditions. Picking...
The difference between greywater and blackwater comes down to contamination. Greywater is the gently used wastewater from showers, bathroom sinks, baths, and washing machines, carrying soap and lint but no fecal matter. Blackwater is the heavily contaminated flow from toilets, and in most codes kitchen sinks and dishwashers, which carries...
A building management system (BMS) is a computer-based control network that monitors and operates a building's mechanical and electrical equipment, including heating, ventilation, air conditioning, lighting, and energy meters. It links sensors, controllers, and software so operators can run these systems from one interface and keep performance steady. Most large...
Terrazzo is a composite surfacing material made from chips of marble, quartz, granite, or recycled glass set into a binder of epoxy resin or cement, then ground and polished to a smooth finish. Architects use terrazzo for floors, stairs, walls, and countertops in airports, schools, hospitals, and homes where durability...
Corten (weathering) steel is a group of low-alloy steels that form a stable, rust-colored patina when exposed to the weather. Small additions of copper, chromium, nickel, and phosphorus let this protective oxide layer seal the surface, so the metal resists further corrosion without paint or coatings in most inland climates....
ETFE (ethylene tetrafluoroethylene) is a fluorine-based plastic foil used as a lightweight, transparent skin for roofs and facades. It is used in stadiums because it weighs roughly one percent of glass, transmits high levels of daylight onto pitch grass, spans wide distances with minimal steel, and shrugs off weather and...
Low-E glass vs standard glass comes down to how each handles heat. Low-emissivity glass carries a microscopic metallic coating that reflects infrared energy while letting daylight through, so a building stays warmer in winter and cooler in summer. Standard glass has no coating and allows far more heat to pass...
A rainscreen cladding system is a multi-layer exterior wall assembly where an outer cladding panel sits in front of a ventilated and drained air cavity, separated from a weather-resistant barrier on the structure behind it. The outer skin sheds most rain, while the cavity drains and dries any moisture that...
A structural insulated panel (SIP) is a load-bearing building component made of a rigid foam insulation core bonded between two structural skins, usually oriented strand board (OSB). According to the U.S. Department of Energy, SIPs replace studs, sheathing, and insulation in one factory-made panel for walls, floors, and roofs. For...
Hempcrete is a natural building material made by mixing the woody inner core of the hemp plant, called hemp shiv or hurd, with a lime binder and water. The mixture sets into a lightweight, breathable block or cast wall that insulates, regulates humidity, and stores carbon, though it is non-load-bearing...
Autoclaved aerated concrete (AAC) is a lightweight precast building material made from sand or fly ash, lime, cement, water and a small amount of aluminium powder, then cured in a high pressure steam chamber called an autoclave. Roughly 80 percent of a finished block is trapped air, which gives AAC...
Beaux-Arts architecture is a grand, formal style of classical design developed at the École des Beaux-Arts in Paris during the 19th century. It combines Greek and Roman orders with Renaissance and Baroque ornament, producing symmetrical, hierarchically planned public buildings rich in sculpture, paired columns, and elaborate stonework. If you have...
The Prairie School style is an American architecture movement that grew in the Midwest between roughly 1900 and 1917. It favors strong horizontal lines, low-pitched roofs with wide overhanging eaves, open floor plans, and a close tie to the flat prairie landscape. Frank Lloyd Wright led the movement alongside other...
Georgian architecture is the classical building style that dominated Britain and its colonies from 1714 to 1830, named after the four King Georges who reigned during that century. It favors strict symmetry, balanced proportion, brick or stone facades, and sash windows, drawing its rules from ancient Greek and Roman models...
Constructivist architecture was a Soviet design movement of the 1920s and early 1930s that treated buildings as social machines rather than decorated monuments. Rooted in the Russian avant-garde, it favored industrial materials like concrete, steel, and glass, exposed structure, and bold geometric form serving the goals of a new collective...
De Stijl in architecture and design was a Dutch movement (1917 to 1931) that reduced buildings, furniture, and painting to straight horizontal and vertical lines, flat planes, and the primary colors red, blue, and yellow plus black, white, and gray. It aimed for a universal visual language stripped of ornament...
