Zonal model - a simplified multiflow element model.

Several models have been developed to study the airflow pattern and thermal distribution in buildings. This paper describes the development of a zonal model that may be incorporated into existing building energy analysis programs. The modeling is detailed in three applications describing how such a model can be simply applied. The model predictions were then compared with measurements and/or Computational Fluid Dynamics (CFD) model prediction.


Keeping the racket down.

Acoustic designers could be costing clients money by over-specifying acoustic solutions. Now, software has been developed that tracks how sound moves through a building and how to stop it

Evaluation of the indoor temperature field using a given air velocity distribution.

A new method for compensating the space discretization error introduced when the fixed flow field is considered for the dynamic models of temperature distribution is presented. It is proved that the method generally used in literature is a particular solution of the proposed one. Moreover, it results in a continuous-time model, for which the integrating method becomes a free choice and a state-space representation is possible.

Natural devices in the urban spaces to improve indoor air climate and air quality of existing buildings.

The role of outdoor spaces’ design as well as the mutual correspondence among urban microclimate, indoor air climate and air quality, have been specifically investigated for the case study of the Central Athens Area. A comprehensive urban design proposal
