1. Unit 2 Terms & Definitions

2.  Legal requirements designed to protect the public by providing guidelines for structural, electrical, plumbing, and mechanical areas of a structure. Building Code

3.  The maximum compressive stress a material can withstand without failure. Compression Strength

4.  The lower part of a building, which transfers structural loads from the building to the soil. Foundation

5.  The moving of soil to affect the elevation of land at a construction site. Grading

6.  The energy needed to warm outside air leaking into a building through cracks around doors, windows, and other areas. Heat Loss

7.  Material used to restrict the flow of heat, cold, or sound from one surface to another. Insulation

8.  The principal pipe artery to which branches are connected. Main

9.  The pressure of water at a given point in a pipe arising from the pressure in it. Pressure Head

10.  The numerical value used to indicate the resistance to the flow of heat. R-Value

11.  Minimum distance that the zoning ordinance requires must be maintained between a structure and property lines or between two structures. Setback

12.  Consideration of the solar orientation of a building based on the relative position of the sun in order to purposely increase or decrease the amount of light or heat transferred to the building. Solar Orientation

13.  Pressure of a fluid due to the head of fluid above some reference point. Static Head

14.  The maximum stress a material subjected to a stretching load can withstand without tearing. Tensile Strength

15.  The process of heat transfer through a solid by transmitting kinetic energy from one molecule to the next. Thermal Conduction

16.  Heat transmission by the circulation of a liquid or a heated gas or air. Thermal Convection

17.  An assembly of structural members joined to form a rigid framework, usually connected to form triangles. Truss

18.  A measure of the heat transmission through a building part (as a wall or window) or a given thickness of a material (as insulation) with lower numbers indicating better insulating properties. U-Factor

19.  A fitting that is used to control the flow of fluid or gas. Valve

20.  The pipe from the water main or other supply to the water-distributing pipes. Water Service
