The building envelope as an air filter

A deep courtyard as the best building form for desert climatean introduction to effects of air movement (Case study: Yazd)

Abstract A basic aim of low energy architecture is to create a thermally comfortable internal environment for building occupants whilst consuming the least possible amount of energy. In desert countries this aim is more difficult to achieve since high ambient air temperatures create a barrier to comfort. Traditional building types of these countries, such as courtyard building, have evolved t...

Improving the Triple Coupled Ring-Resonator Performance as an Optical Filter

In this paper, a three ring-resonator serially coupled is considered as an optical filter. We are going to improve the performance of the designed optical filter by increasing the quality factor and finesse of filtered wavelengths. The first and last rings are coupled to the bus waveguides that carry the input and output fields. The effect of coupling parameters and ring radii on the filtering ...

Air filter materials, outdoor ozone and building-related symptoms in the BASE study.

UNLABELLED Used ventilation air filters have been shown to reduce indoor environmental quality and worker performance and increase symptoms, with effects stronger after reaction of filters with ozone. We analyzed data from the US EPA Building Assessment Survey and Evaluation (BASE) study to determine if ozone and specific filter media have interactive effects on building-related symptoms (BRS)....

Dynamic Envelope and Control Shading Pattern to Visual Comfort of Office Building in Tehran

This work reviews the effect of parametric programming on visual performance, daylighting and shading in office buildings in Tehran-Iran and studies their influences that help not only to reduce the glare but also to promote useful daylight illuminance through promoting visual comfort. It starts by establishing a review of the effective parameters on visual comfort indices, glare indices, and d...
