eToolLCD V2 introduced some pretty neat functionality that allows users to enter formulas or expressions into some fields.  This is particularly useful for building operational energy templates, for example, based on building size or occupancy.  We have used a third party calculation library to enable this functionality, the list of available operators and functions is available here.

We also have a number of variables that relate to the design that can be used in expressions.  The list of these is provided below (with default values that are used in library template calculations before loading into a design):



 Default Value 

Occupancy Occupancy of the structure 2
Fully Enclosed Building Area Fully enclosed building area of the design 225
Estimated Design Life Estimated design life of the structure 50
Maximum Durability Ceiling The maximum structural life of the structure 150
Design Template Quantity The template quantity field that is filled out when uploading a template into a design 100


This functionality has dramatically improved the ease at which we can predict operational energy in designs and we’re enjoying using it here at eTool.  We will be adding more stored variables as time passes, watch this space.  To learn how to utilise this functionality, please get in touch for some training
