Análisis de la influencia, en la demanda de climatización, de estrategias pasivas en viviendas con grandes superficies acristaladas, mediante un código de simulación. La casa Farnsworth = Analysis of the influence, in climate control demand, of passive strategies in houses with large glazed surfaces, by means of a simulation code. The Farnsworth house

Reducing energy expenditure in the construction sector requires the implementation of passive strategies in buildings. In Spain, consumption is centered on air conditioning systems associated with the demand for the building’s thermal envelope. A critical point of the enclosures is represented by glazed holes where much of the energy that is consumed is lost; however, homes increasingly tend to have large window openings due to the comfort and visual well-being they provide to users. In this study, we focus on an extreme case, analyzing a fully glazed house in its four orientations. It is necessary to evaluate the most energy efficient passive strategy for this type of construction. The results are based on the temperature analysis obtained during the monitoring of two scale models of a glass house. The results indicate that solar control foil glasses perform better in warmer weather stations. Regarding the cantilever installation, it influences the interior temperature and the central hours of the day, mitigating the increase in temperature as well as slowing the nighttime cooling.

“…Furthermore, the presence of people in confined spaces for a higher number of hours per day may imply an increase in the concentration of CO 2 (Giechaskiel, 2020;Rossi et al, 2020). Obviously, with the increase in time spent indoors, the time of use of appliances, lighting, heating, etc., increases, which can also increase the amount of CO 2 released (Heinonen et al, 2016;Aguilera et al, 2018).…”

After the arrival of a new airborne virus to the world, science is aiming to develop solutions to withstand the spread and contagion of SARS-CoV-2. The most severe among the adopted measures is to remain in home isolation for a significant number of hours per day, to avoid the spreading of the infection in an uncontrolled way through public spaces. Recent literature showed that the primary route of transmission is via aerosols, especially produced in poorly ventilated inner spaces. Spain has reached very high levels concerning contagion rates, accumulated incidence, or number of hospitalizations due to COVID-19. Therefore, this article aims to develop a quantitative and qualitative analysis of the requirements established in Spain, with respect to the European framework in reference to ventilation parameters indoors. The different parameters that serve as calculation for the ventilation flow in homes are analyzed to this aim. Results show that the criteria established in the applicable regulations are insufficient to ensure health and avoid contagion by aerosols indoors.

After the arrival of a new airborne virus to the world, science is aiming to develop solutions to withstand the spread and contagion of the SARS-CoV-2 coronavirus. The most severe among the adopted measures is to remain in home isolation for a significant number of hours per day, in order to avoid the spreading of the infection in an uncontrolled way through public spaces. Recent literature showed that the major route of transmission is via aerosols produced especially in poorly ventilated inner spaces. With regard to contagion rates, accumulated incidence or number of hospitalizations due to COVID-19, Spain has reached very high levels, therefore this article develops a quantitative and qualitative analysis of the requirements established in Spain with respect to the European framework in reference to ventilation parameters indoors. For this, a case study has been analyzed, representing a common residence in current Spanish residential developments. Results show that the criteria established in the applicable regulations are not sufficient to ensure health as well as to avoid contagion by aerosols indoors.
