| Sumario: | Urban population growth together with energy demand increase, among other consequences, provokes the augment of greenhouse gasses emissions (GGE), which contribute to Climate Change. Energy efficiency in buildings becomes essential to reduce demand, keeping acceptable comfort levels for users. Office, housing and commercial buildings consume more than one third of the primary energy produced in Argentina, a similar percentage worldwide. New digital technologies to afford this complex problem combine architectural design and building energy modelling (BEM), like parametric architecture. This tool enables complex tasks as energy efficient building design where materials, energy and information must be considered simultaneously. All these variables can be gathered into one unique transparent process, putting forward energy demand as a key factor for conceptual design decisions. In this paper, we compare the heating demand for one typical winter day with the demand of a house audited by our Laboratory, in order to calibrate our model. The audit shows the results before and after energy efficiency refurbishment. We also calculate the cooling demand for one typical summer day for a future comparison with the audited building. |
