The Influence of an Integrated Driving on the Performance of Different Passive Heating and Cooling Methods for Buildings

摘要

Passive cooling and heating methods within buildings are studied a lot nowadays. Nevertheless, their performance considering their driving has not been deeply studied. Therefore, the performance of the most common passive heating and cooling methods is analyzed in this document. The methods are divided into three categories: operable, semi-operable, and not operable. They are studied under different conditions of operation in order to estimate their performance in terms of indoor temperature increase/decrease in a single dwelling. The study is carried out with the thermal simulation program EnergyPlus, using a dwelling in Mexico City as a case study, which is validated with literature that studied passive methods for similar climates. Furthermore, for an integrated driving, four features of operation of the passive methods are considered: mobility, maintenance, assembly, and consumables. The results show that a correct use of these features of driving might achieve a significant temperature drop in the case of cooling and a significant indoor temperature increase in the case of heating. This is reflected in a considerable amount of energy saving compared to a conventional heating/cooling heat-pump system running under regular conditions, which is taken as a reference of consumption. Thereby, it is concluded that the proper usage, considered here as the correct application of the four features of operation mainly by the occupants, might have a high influence in their performance of increase/decrease of the indoor temperature. Thus, it is highly recommended to follow up their performance once installed and not to suppose an optimal performance ever after.
