Abstract: A cost modeling system typically used for construction projects reliant on 3D computer aided design (CAD) files. It enables a computing system to rapidly generate accurate, real-time parametric cost models of proposed building designs based on either data inputs from users or a from a three-dimensional model, or various combinations thereof, which may then be presented to a user of the computer system (e.g., a construction professional). Data may be inherently stored within the CAD file properties itself or may be selectively input by the end user or a combination thereof.

Abstract: A dehumidifying element includes a super absorbing polymer (SAP), and a hygroscopic base, thereby maintaining hygroscopic characteristics regardless of aging and a high humidity absorbing rate and needing a smaller amount of energy for regeneration.
