Computational fluid dynamics (CFD) can provide detailed information of flow motion, temperature distributions and species dispersion in buildings. However, it may take hours or days,

A jet of cold air is denser then ambient air but it adheres to the ceiling of the room over the given distance when it is blown horizontally close to it.

Since district heating (DH) is the dominating heating system in Scandinavia, and fairly common in large parts  of Europe, it is of vital interest to study the possibility  for b

The ability to simulate the effect of trees on natural light performance in buildings is contingent upon accurate simulation of light passing through the canopy.

To reduce the potential problems of window systems such as undesired heat gain (loss), glare, and thermal discomfort due to asymmetric radiation, double-skin systems have been introd

This paper discusses a procedure for the two-way run time external coupling between Building Energy Simulation (BES) and building envelope Heat, Air and Moisture (HAM) programs for e

The present paper describes heat pump systems and their energy efficiency. In the first part of the paper the modelling of heat pump system is presented.
