Challenges in designing for comfort – Comfort and energy use characterization in residential apartments

This article presents the results of a thermal comfort investigation carried out in a residential gated community located in a hot-humid climate.  The study comprises of real-time field monitoring of thermal comfort in representative apartment units and assessment of the utility and cooling energy consumption in these residences.  Utility energy consumption data of the residences for one year period was obtained and a survey was administered to identify the trend of air-conditioner use.  The results are summarized and used to validate a simulation model.

National calculation tool for epbd energy performance certification

Paper is focused on description of Czech national methodology and tool for energy performance calculation according to EPBD (Energy performance building directive 91/2002). Energy performance calculation is expressed by total annual energy consumption, including heating, cooling, ventilation, auxiliary and other energy required for building operation. There is a simplified multizone model, loaded by typical day for each month in hourly time step. Climate data are synthetic data for 4 climate zones according to standards, used for building physics calculation.
