Resumen

It is a drip cap which works as a passive, eco-efficient and sustainable system to optimize and harness architectural resources, through the adaptation of inclined plane slopes, replacing their function of drip caps and turning them into surfaces which reflect undesired direct solar radiation, so that they contribute to low power consumption during warm months in massive building. It shields the interior from solar incidence and reduces energy flow through the enclosure openings, reducing heat gain, accumulation and penetrations by conduction and reflected radiation, suppressing a traditional heat bridge.

1. Drip cap with discharge adaptation to protect building openings and their inside against direct solar radiation reflected from its surface, characterized in that its outer face has a plane slope forming an angle symmetric to the incident radiation calculated so that it reflects it, heliocentrically considering the planetary and orbital movement of the building, its geodesic position and orientation and the altazimuth coordinates of the sun at a given time of the year and at a specific time of a given day (data included in tables 1, 2, 3 and 4). 2. Drip cap with discharge adaptation to protect building openings and their inside against direct solar radiation reflected from its surface, according to claim 1, characterized in that the theoretical or graphic calculation (Figures 2, 5 and 6) of the drip cap slope considers the solar radiation incidence in a 90° angle with three important directions (normal and bisecting lateral ones) according to the azimuth, centering said arch in front of each one of the openings, and starting at their axis of symmetry, calculating the least favorable incidence according to its shortest (solar) altitude, and determining with it the adaptation of the slopes or discharges for the desired reflection. 3. Drip cap with discharge adaptation to protect building openings and their inside against direct solar radiation reflected from its surface, according to claims 1 and 2, characterized in that it can be applied to already existing buildings and by having a metallic sheet skirt, forming the new reflecting slope (5), which is folded and stiffened on itself, housing an insulation body inside it to which it is attached, as wedge or boss (6), which is placed on top of the already-existing drip cap, fixed to the opening base and comprising two protruding pins for its mechanical anchoring to both sides of the opening soffit. 4. Drip cap with discharge adaptation to protect building openings and their inside against direct solar radiation reflected from its surface, according to claims 1 and 2, characterized in that it can be applied to a new construction to configure the different drip caps in a heliodynamic way, according to the orientation of the facades.
