This paper proposes a computational building design support framework. The framework evaluates and optimizes building envelope systems, electrical systems and HVAC systems simultaneously with the assistance of a newly developed EnergyPlus component cost database. The integrated building system evaluation could potentially reveal the trade-offs among different building systems and help clients a...

A new hygrothermal building model is being developed within the research project GENSIM by the Fraunhofer institutes FIRST and IBP. The model implementation takes place by using the objectoriented modeling language Modelica. As a starting point for the development of the new building model, the researchers used the physical models of the simulation tools WUFI (hygrothermal wall simulation) and ...

Micro-electromechanical systems (MEMS)-based sensors have seen significant improvements in accuracy and cost over the past several years, due to need for altitude sensing unmanned aerial vehicles wearable technologies, absolute pressure shown most dramatic improvements. This paper investigates applications of MEMS commercial buildings, including pairing two determine differential pressures betw...

Abstract The building envelope acts as a shield against varying weather conditions and modulates thermal energy flow between outdoors indoors. choice of layers used in the assembly impacts heat loss gain through wall structure potentially can affect comfort Thus, plays an essential role performance building. Optimizing cladding design has recently become increasingly important to reach sustaina...

Mutations in nuclear lamins or other proteins of the nuclear envelope are the root cause of a group of phenotypically diverse genetic disorders known as laminopathies, which have symptoms that range from muscular dystrophy to neuropathy to premature aging syndromes. Although precise disease mechanisms remain unclear, there has been substantial progress in our understanding of not only laminopat...

As part of the adoption of the 2005 Building Energy Efficiency Standards, the California Energy Commission adopted Joint Appendix IV, which contains standard U-factor, C-factor and Thermal Mass data for roof, wall and floor construction assemblies (see page IV-1 of the Joint Appendices at: http://www.energy.ca.aov/title24/2005standards/2004-10-06 400-03-001JAF.PDF). The data in Joint Appendix I...

Loss-of-Control (LOC) is a major factor in fatal aircraft accidents. LOC is generally associated with flight outside of the normal flight envelope almost always involving nonlinear behaviors and often including extreme attitude conditions. Recent and ongoing work at the NASA Langley Research Center has focused on building aerodynamic models adequate for simulation and analysis in these regimes....
