  • CAD, or computer-aided design and drafting (CADD), is the use of computer technology for design and design documentation. CAD software replaces manual drafting with an automated process. AutoCAD software was the first CAD program, and it is still the most widely used CAD(...)
  • CAD/CAM refers to computer software that is used to both design and manufacture products. CAD/CAM applications are used to both design a product and program manufacturing processes, specifically, CNC (computer numerical control) machining. CAD/CAM software is most often used for machining of(...)
  • CAM software is used to design and manufacture products. CAM software uses the models and assemblies created in CAD software to generate tool paths that drive the machines that turn the designs into physical parts. Source: http://www.autodesk.com/solutions/cad-cam,(...)

  • Cellulose is made from recycled newsprint and other recycled paper with one of the highest percentages of post-consumer waste content of any insulation. It is treated with recognized safe fire retardants. Cellulose insulation is blown onto attic floors, into wall and ceiling cavities, or is(...)
  • An individual who has trained (taken a Passivehouse-Institute-of-the United States [PHIUS]-recognized Certified Passive House Consultant [CPHC] course and PHIUS CPHC examination) and qualified in the principles and methodology needed to design a Passivehouse. Source: PHIUS
  • A material or assembly that forms the exterior face of a wall. Examples of cladding include stucco, EIFS, metal panels, brick/stone veneer, wood siding, and vinyl siding. Source: IRC FAQ: Cladding Attachment Over Insulating Sheathing, Info-305: Reservoir Claddings, BSI-058  
  • The exterior environmental conditions that will impose a load on the building enclosure, including temperature, humidity, rainfall, wind, and solar radiation. Dividing a map into climate zones allows designers, code bodies, and others to make recommendations based on expected regional(...)
  • A climate zone is a classification of the type of weather that is experienced in a specific geographic region of the world.  Climate zones are differentiated based on average temperatures, precipitation, and heating degree-days (HDD) that occurs in an area.  The US Department of Energy(...)
  • A quality assurance process during and following building construction, prior to occupancy. Tests and inspections should note any problems to be fixed immediately (“fix and tune”). Tests should be conducted for duct leakage, building enclosure leakage, air pressure relationships under all(...)
  • The change of state from vapor to liquid. A common factor in moisture damage. Occurs on surfaces, which must be cooler than the air containing vapor next to it. Vapor supply to the condensation surface is usually by airflow but can be by diffusion. Source: BSD-163: Controlling Cold-Weather(...)
  • The part of the building that is designed to be thermally conditioned (heated or cooled), either for the comfort of occupants or for other reasons such as preserving temperature-sensitive goods. Source: BSI 022: The Perfect HVAC
  • A Connected Home is a home that contains a communication network that connects security, lighting, sound, TV’s, appliances, HVAC, and energy monitoring allowing the owner to control the network from a single app on a tablet, phone, or computer both locally and remotely.
  • Heating degree days and cooling degree days are climatological metrics used to express the magnitude of the heating or cooling load in a given location. These metrics are expressed in terms of a "base temperature" (e.g., "Cooling Degree Days Base 65 F"). Cooling degree days are calculated by(...)
  • The deterioration of metal by chemical or electrochemical reaction resulting from exposure to weathering, moisture, chemicals or other agents or media. Source: RR-0605: Assessing the Durability Impacts of Energy Efficienct Upgrades Using Hygrothermal Modeling
