4. D BASAT is a structured spreadsheet tool that can be used to assess Building Automation Systems and provide insight into any specific controls optimizations of or measures that can be realized with the current BAS configuration as well as an indication of the possible measures given additions of specific sensors actuators and points to the BAS The tool consists of the following e Input sections in the form of survey lists in which the user selects the availability of sensors based upon examination of the BAS front end and operator knowledge of the system e System equipment and protocol specific results sections in which the results of the survey are computed based on a decision matrix that determines the availability of measures control strategies and controls optimizations NAVIGATION Much like any other workbook the various sections of BASAT represented by individual spreadsheets can be accessed by clicking on the spreadsheet label tab located at the bottom of the Excel window as shown in the figure below Figure 1 BASAT sections as spreadsheets BASAT STRUCTURE BASAT can be used to evaluate the capabilities of a BAS in two ways 1 to look at the specific capabilities or measures available to the BAS for a certain building system e g Cooling Plant Heating Plant etc and 2 to determine the level of compliance with a specific protocol e g Demand Response NYC Local Law 87 In its current iteration 2
