The aim of the present study was to determine the applicability of a genetic algorithm for the optimization of daylighting systems, as well as the requirements for the lighting simulations to be used. Furthermore, by testing the daylighting perfor

Quantification of natural ventilation rates is an important issue in HVAC system design.
Se-Hoon Hyun, Cheol-Soo Park, Godfried Augenbroe
The buoyancy-driven natural ventilation of a room with large lower and higher level openings is investigated by both theoretical analysis and CFD simulation.
Rong Li, Adrian Pitts, and Yuguo Li
Assessments based on CFD snapshots of stable conditions within strongly transient domains do not address many aspects of performance associated with occupant interventions, control actions or changing climate. Such domains (e.g.

Building use modes are important for energy consumption simulation. But few research concerns building use modes, such as people behavior of opening/closing window, room temperature for airconditioner running, and air-conditioning space and time.

A liquid desiccant fresh air processor is presented whose driven force is low-grade heat (65~70℃ hot water). Inside the processor, the desired cooling source for air’s dehumidification is indoor exhaust air’s evaporative cooling energy.

In the internally-cooled liquid desiccant dehumidifier (ICLDD), cooling medium is introduced to carry away the vaporization latent heat, which enhances effectiveness of heat and mass transfer process between liquid desiccant and air.

Occupant evacuation dynamics is a kind of manybody system of strongly interacting persons. A great deal of factors should be taken into account in the study of fire evacuation, such as human behavior, fire products and architecture.
