Resumen
This work consists of the integrated design process analyses with thermal energetic
simulation during the early design stages, based on six practical cases. It aims to schematize
the integration process, identifying the thermal energetic analyses contributions at each
design phase and identifying the highest impact parameters on building performance. The
simulations were run in the DesignBuilder energy tool, which has the same EnergyPlus engine,
validated. This tool was chosen due to the flexible and user friendly graphic interface for
modeling and output assessment, including the parametric simulation to compare design
alternatives. The six case studies energy tools are three architectural and three retrofit
projects, and the author the simulations as a consultant or as a designer. The case studies
were selected based on the commitment of the designers in order to achieve performance
goals, and their availability to share the process since the early pre-design analyses, allowing
schematizing the whole process, and supporting the design decisions with quantifications,
including energy targets. The thermoenergetic performance analyses integration is feasible
since the early stages, except when only a short time is available to run the simulations. The
simulation contributions are more important during the sketch and detail phases. The predesign
phase can be assisted by means of reliable bioclimatic guidelines. It was verified that
every case study had two dominant design variables on the general performance. These
variables differ according the building characteristics and always coincide with the local
bioclimatic strategies. The adaptation of alternatives to the design increases as earlier it
occurs. The use of simulation is very useful: to prove and convince the architects; to quantify
the cost benefits and payback period to the retrofit designer; and to the simulator confirm the
desirable result and report the performance to the client
