Solution Overview
Problem
Existing building constructions with heliodynamic architecture face challenges in optimizing solar radiation control for both heating and cooling, with a trade-off between solar exposure and habitability, particularly in conventional forms and collective residences.
Innovation Solution
A building facade design that incorporates recessed and domed frustoconical portions inscribed within a conical surface, with the facade's outer face set back and inclined inward, allowing for controlled solar exposure and internal shading, maximizing brightness and comfort throughout the year.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the Heliodome form is incorporated to maximize solar radiation exploitation, then solar lighting and heating performance is improved, but the internal space becomes difficult to exploit and the construction complexity increases
Solution Approach 1:
The facade is divided into multiple transparent sections (first, second, third transparent facades) that can be independently configured. Each segment follows the heliodynamic principle but can be adapted to different building requirements, reducing overall complexity while maintaining solar exploitation benefits
Solution Approach 2:
The invention transitions from the three-dimensional Heliodome form to a two-dimensional facade application. By applying the heliodynamic principle to flat or slightly curved facade surfaces rather than full volumetric forms, the solution maintains solar control capabilities while dramatically simplifying construction and improving internal space usability
2Illumination intensity
If the Heliodome form is extended to improve internal brightness, then solar lighting is improved, but the risk of overheating during strong insolation periods increases
Solution Approach 1:
Different facade sections have different orientations and transparency characteristics. The first transparent facade faces east, the second faces south, and the third faces west, allowing each section to be optimized for its specific solar exposure pattern. This local differentiation enables bright interiors while controlling overheating through selective solar admission
Solution Approach 2:
The facade design dynamically adapts to the sun's movement throughout the day and year by using multiple oriented sections. The geometry of each facade portion is designed to capture or reject solar radiation at different times, providing adaptive lighting and temperature control without mechanical systems
3Ease of manufacture
If a conventional building form is used to simplify construction, then ease of manufacture is improved, but the controlled exploitation of solar radiation is reduced
Solution Approach 1:
Rather than requiring the complete Heliodome form, the invention applies the heliodynamic principle partially to specific facade portions. This partial application is sufficient to provide significant solar control benefits while maintaining conventional building forms and construction methods for the rest of the structure
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves optimal solar heating in winter and shading in summer, maintaining a cool and bright interior by aligning facade forms with sun trajectories, enhancing habitability and appearance.
Implementation Method 1
a facade which delimits an outside and an inside, which is transparent to the solar radiation, substantially over its entire surface
Implementation Method 2
the form of at least a part of said at least one facade portion being inscribed substantially within the conical surface generated by an imaginary segment extending between the Sun and a corresponding point which is fixed with respect to the Earth

AI summary
A building has outer envelope that has at least one facade portion which is transparent to solar radiation and that is situated on a face of the building, the shape of at least a part of which can be inscribed inside the surface generated by an imaginary segment extending between the sun and at least one fixed point that is fixed relative to the Earth. Facade portion(s) extend between a base line and a top edge which together delineate it from the remaining part of the outer envelope of the building, which is predominantly or completely opaque. The exterior face of each part of the facade portion is, at each point on the top line, set back from a straight line perpendicular to the local horizontal plane, and therefore normal to the plane of the ground, and passing through this point. At least one of the facade parts can be inscribed inside the surface of a cone frustum part that is recessed or concave relative to the face concerned.
