Internal Versus External Shading Devices Performance in Office Buildings

Genetic Optimization of External Shading Devices

A genetic optimization approach has been used for the design of an external shading device in an office with a window and different glass characteristics. The primary energy consumption for heating cooling and lighting have been minimized. Simulations have been performed using the energy code ESP-r and lighting simulation package Radiance, the optimization loop has been driven by the software t...

Integrating Air Handling Units in Office Buildings for High Performance

Profitability versus safety of high-rise office buildings

The paper applies a computer-based method involving stochastic search, multi-criteria optimization and color filtering to investigate the tradeoff between the life-cycle profitability of highrise commercial office buildings and their load-path safety against progressive collapse under abnormal loading. The study was motivated by the progressive-collapse failure of the twin towers of the World T...

External versus Internal Distraction Devices in Treatment of Obstructive Sleep Apnea in Craniofacial Anomalies

BACKGROUND Obstructive sleep apnea is often associated with congenital craniofacial malformations due to hypoplastic mandible and decreased pharyngeal airway. In this study, we will compare external and internal distraction devices for mandibular lengthening in terms of effectiveness, results, patient comfort, and complications. METHODS Thirty-seven patients were treated by bilateral mandibul...

The Energy Performance of Office Buildings throughout Their Building Process

Many innovative techniques and policy measures have been introduced to reduce energy consumption. Despite the high ambitions and societal pressures, the adoption rate of energy measures in office buildings is still low. Using adoption theories this paper provides a framework to analyse the adoption process of energy saving techniques in building processes. This framework is used to analyse the ...
