- Estudio comparativo de los costos de inversión, operación y rentabilidad de una vivienda con principios bioclimáticos y una convencional, en un clima semifrío seco caso de estudio: viviendas de la Ciudad de Guadalupe, Zacatecas(Universidad Autónoma Metropolitana (México). Unidad Azcapotzalco. Coordinación de Servicios de Información., 2009-06) ACUÑA VALERIO, ANA JULIETAThe purpose of this thesis was to verify qualitative and experimentally, if the operation of a house designed with some bioclimatic criteria presents better performance than a conventional house considering hygrothermal comfort, energy efficiency and economic profitability. This was carried out based on an exercise of comparison in which the levels of comfort of two dwellings of the city of Guadalupe, Zacatecas were evaluated: one of them was considered as a "dwelling with bioclimatic principles" and the other as a "conventional" dwelling. During the monitoring both houses were evaluated constantly, it lasted nine months. Monitored interior parameters were temperature, relative humidity and luminance, nevertheless they were recuperated exterior data of temperature, humidity, solar radiation, wind. Another evaluation way was the application of the draft of standard 020 to estimate the dwelling’s energy efficiency, as well as an energy audit to analyze the electrical consumption by air conditioning inside them. According to the results of the standard draft some modifications were done to the cases of study, these were considered as investment costs and they were contrasted with the operation costs that were determined with the energy audit. This permitted to carry out a benefit cost analysis of some measures that they could improve the thermal comfort of both houses. The obtained result was a better performance by the dwelling with bioclimatic principles as much as in the environmental monitoring as in the application of the standard. Once you compare the results and the economic analysis, it is shown at the end of this thesis, that the application of bioclimatic architecture is profitable. Also the results allow us to establish that the construction of dwellings in the municipalities of Guadalupe and Zacatecas may reach good levels of hygrothermal and luminic comfort throughout the year, if considering in bioclimatic design. Nevertheless this work also shows how it is possible to improve comfort in conventional dwellings with profitable investments.
