This study demonstrates a design of a code-compliant, highrise mass timber apartment tower in Los Angeles. Using the existing reinforced concrete Museum Tower Apartment building in downtown Los Angeles as a basis, the study demonstrates architectural, structural and fire performance improvements and trade-offs of the mass timber design compared to the reinforced concrete design. The... Read more »

ABSTRACT: The paper will discuss the design of a bi-directional thermo-hygroscopic façade as a dedicated outdoor air system to cool and dehumidify outside air. The system is a variant of dedicated outdoor air systems to separate dehumidification and cooling in air-conditioning equipment and locates components within the building envelope. The integrated hybrid-building envelope relies on... Read more »

ABSTRACT: Available energy analysis and optimization methods do not produce fast and accurate enough results to provide guidance to professional design teams making massing and technology decisions. This paper proposes two methods using the reduced-order Energy Performance Calculation (EPC) toolkit with parametric building models and optimizers in Rhinoceros, Grasshopper and MATLAB to provide rapid feedback...
