Abstract
A significant potential for energy consumption reduction in buildings lies on using a mixed-mode system for space conditioning, which consists on a combination of natural ventilation and mechanical systems for cooling. In spite of being a strategy commonly used in office buildings, it can be noticed that there are few technical information about its performance. Therefore, the aim of the present study is to develop metamodels for energy analysis of mixed-mode office buildings located at Sao Paulo city, intended to be used by architects in early design stages. The metamodels development will include the following steps: building a database of mixed-mode buildings; applying sampling methods to generate combinations of parameters of interest; running a large amount of building simulations; identifying key parameters, of greatest impact on the outcomes and applying statistical methods over the computer simulation results, aiming to generate metamodels. The metamodels will assist the architectural design development, considering that the mixed-mode system requires a well-designed building envelope in order to guarantee a better use of natural ventilation and scaling back the use of mechanical cooling. The energy performance will be quantified through the following variables: thermal loads, air conditioning energy consumption and CO2 emission factor. This work can contribute to the dissemination of the mixed-mode system as an alternative to energy consumption reduction of buildings and resultant reduction on greenhouse gas emissions, maintaining acceptable patterns of thermal comfort to the occupants.
