• Method of performance evaluation for climate-adaptive building envelopes. • Integration of CABE behavior generation and performance simulation using a BEM. • Improvement of the validity of CABE performance. • Assessment of alternative complex three-dimensional CABE geometries. • Assessment of alternative patterns of a CABE's adaptive operation. This research presents a new method for evaluating the energy performance of climate-adaptive building envelopes (CABEs) called parametric behavior maps (PBMs). There are three main challenges when evaluating a CABE for energy performance that are not overcome by the currently accepted process: (1) representing complex three-dimensional dynamic geometry; (2) generating various candidate CABE control scenarios by integrating environmental factors and their thresholds; and (3) representing a CABE's time-varying behavior within a single building energy model (BEM). To overcome these challenges, the PBM method was developed. This method makes two key contributions to the field of performance-driven building design. First, it is capable of generating hourly CABE operation scenarios to evaluate CABE performance using a single BEM, regardless of dynamic operation and any geometric complexity. Second, the PBM method is superior at handling the effects of thermal energy storage with dynamic operations than is the currently accepted process. The reliability of the PBM method was validated by comparing indoor temperature profiles obtained from a PBM and the existing method. The new method enables designers to integrate the energy performance of a CABE system with multiple control scenarios, ultimately improving the building design process. [ABSTRACT FROM AUTHOR]

Insufficient interoperability resulting from complex data exchange between architectural design and building energy simulation prevents the efficient use of energy performance analyses in the early design stage. This paper presents the development of a Modelica library for Building Information Modeling (BIM)-based building energy simulation (ModelicaBIM library) using an Object-Oriented Physical Modeling (OOPM) approach and Modelica, an equation-based OOPM language. By using the ModelicaBIM library, our project investigates system interfaces between BIM and energy simulation, which can perform semi-automatic translation from the building models in BIM to building energy modeling (BEM) using a BIM's authoring tool's Application Programming Interface (API). The ModelicaBIM library consists of OOPM-based BIM classes and OOPM-based BIM structure. OOPM-based BIM classes represent building component information. OOPM-based BIM structure consists of test case models that demonstrate (i) how building information in BIM can be transformed to OOPM and (ii) how design operations in BIM, such as changing a building geometry and editing building components, can be translated into BEM. A case study for simulation result comparisons has been conducted using (i) OOPM-based BIM models in the ModelicaBIM library and (ii) LBNL Modelica Buildings library (a Modelica-based building thermal simulation library developed by Lawrence Berkeley National Laboratory). Our implementation shows that the ModelicaBIM library enables (i) objects in BIM to be translated into the OOPM-based energy models and (ii) existing OOPM library to be utilized as a simulation solver for BIM-based energy simulation.
