Rises a little higher each time, up to 74º it is never vertical, and continuing towards the winter solstice, the sun positions itself lower and lower, up to 27º. Regarding the rising and setting, on the winter solstice, they move 31º to the south, and on the summer solstice 21º to the north. It should also be taken into account that solar time is not the official time. For example, in cáceres, to evaluate the solar time, 2h 25' in summer and 1h 25' in winter must be subtracted from the official time. These solar paths that we have just explained have a fairly clear consequence on the radiation obtained by vertical facades: in winter, the southn summer, however, when the sun is more perpendicular at midday, the south façade receives less direct radiation, while the mornings and afternoons especially hit the east and west façades, respectively. Heat capacity and thermal inertia if we give heat to a body, it increases its temperature. If it does so slowly we say that it has a lot of heat capacity, since it is capable of accumulating a lot of heat for each degree celsius of temperature. The singularities of heat capacity between water and oil, for example, greater in the first than the second, is what means that, when exposed to fire, water takes longer to ignite than oil, but also causes water to retain heat longer.
Heat capacity and heat accumulation bring about some phenomena. For example: in a house, in winter, when we turn on the stove when we arrive in the afternoon, the room takes time to reach a comfortable temperature, and when we turn it off at night, the temperature of the room is still good and it Singapore Phone Number doesn't cool down immediately. This also happens in the seasons: in the northern hemisphere, on april 21 (spring equinox) the sun is in the same position as on september 21 (autumn equinox). However, temperatures are higher on this last date, for the simple reason that the earth still (keeps) the summer heat, which it will lose little by little. This "Resistance" of temperature to respond immediately to heat input is what we call thermal inertia. Regarding bioclimatic architecture, this is a more than fundamental concept in homes that are bioclimatic: if they have little thermal inertia, they will react quickly to solar radiation. They rise quickly during the day, speaking of winter, but they also cool faster at night: the delay between heat input and the temperature obtained is small.
On the other hand, in houses with a large thermal inertia, solar radiation will not cause a rapid rise in the temperature of the home, because the heat is accumulating, and is subsequently released slowly at night. Therefore, a violent decrease in temperature will not occur. Also, temperature variations are dampened, not achieving such extreme values. Therefore, thermal inertia in a house entails two phenomena: that of delay of the interior temperature with respect to the exterior temperature, and that of damping (the interior variation in temperature is not as large as the exterior variatioires its design, but is even influenced by its location. The reality of natural features such as mountains, streams, swamps, vegetation, or artificial features such as nearby buildings, etc. They create a microclimate that damages the wind, humidity, and solar radiation that the home receives. If a bioclimatic home is to be built, taking into account bioclimatic architecture, the first study must address the climatic conditions of the region and, later, the microclimatic conditions of the specific one.
