Facilities Inventory Terms and Definitions

Facilities Inventory Purpose

Angelo State University facilities constitute a significant resource for the state, and as such, there is a requirement to account for the use of the space. The Office of Business Services is responsible for maintaining an accurate inventory of ASU facilities and providing a reliable reporting system to file essential annual reports to the Texas Higher Education Board (THECB). These reports are important factors in the determination of Higher Education Assistance Funding (HEAF) and serve as principal considerations for capital project approval. 

Facilities Inventory Process

ASU certifies the facilities inventory each year in a submission to the THECB. The Office of Business Services uses the annual unit Space Inventory Facilities Reports to validate the accuracy of facilities inventory information annually.  Facilities inventory changes occurring throughout the year must be submitted to the Office of Business Services on a Space Change Request Form.

Classification of Space

The coding structure for classification of space is outlined in the THECB Summer 2012 Reporting and Procedures Manual for Texas Public Universities and The Summer 2012 Appendices to the Reporting and Procedures Manual.

Information to code rooms according to architectural features can best be obtained by a visual inspection of each room. Each room has one best Space Use Code based on its exclusive or predominant design/use. Space Use Codes change when a room’s predominant use or physical characteristics have been changed and/or remodeled. The evaluation of a room’s Space Use Code, Functional Category Code, and CIP should be assigned based on the judgment of a departmental representative familiar with the actual use of the space. 


While a room’s Space Use Code cannot be prorated, up to three Functional Category Codes and three CIP Codes may be assigned to a single room: primary, secondary, and remaining. Where a room serves several purposes or uses, it may be reported based on time spent on each activity. Overall, the total percent of use/proration for primary, secondary, and remaining use must always total 100 percent.

Type Refers to Space Use Code—The code that indicates the primary activity area or service area of the space (Common Code Definitions listed below)

CIP Classification of Instructional Programs are used to establish standard terminology of education program descriptions and title codes that identify academic disciplines, instructional programs, or departments. The most common code 000000 is for Instructional Classroom all other codes are departmental identifiers. Complete index of valid CIP codes and definitions. 

Use Code Refers to Functional Category Code - Code that profiles the actual use/function of a room and helps determine its type of space

Percent The percentage of the type used in the space

NASF The sum of all areas within the interior walls of rooms.  NASF includes auxiliary space and E&G space

E&G Space used for teaching, research, or the preservation of knowledge, including the proportional share used for those activities in any building or facility used jointly with auxiliary enterprise, or space that is permanently unassigned.
