Case Study of Building Model Production for Photovoltaic Sunroom
1、 Project Overview and Objectives
The aim of this project is to create a 1:20 scale “photovoltaic sunroom” display model. The core goal of the model is to accurately reproduce the unique blend of Chinese and Western styles in the architecture depicted in the image, as well as the integrated relationship between the photovoltaic ceiling and the main building. The focus is on depicting the color and structural contrast between the beige wall, reddish brown carved fence, and dark gray photovoltaic ceiling, and creating a realistic sense of living scenes through detail processing. The overall restoration degree strives to reach over 90%.
2、 Material selection: Establishing a true texture
The texture of the model comes from careful selection of materials:
Main structure: The building’s main body (walls, floors) is made of 5mm thick high-quality oak plywood. Wooden materials are easy to cut and carve, and their natural texture can simulate the texture of real buildings after processing. They also have high structural strength and can stably support the overall model.
Exterior wall and fence: The first layer of beige exterior wall is covered with 1mm thick ABS board to achieve a smooth and flat finish. The red brown carved fence on the second floor is a visual highlight, using laser engraving technology to accurately carve out traditional window lattice patterns on high-density acrylic panels, ensuring clear and consistent patterns.
Photovoltaic ceiling and glass: The huge photovoltaic panel ceiling is made of frosted dark gray acrylic panels to simulate the matte texture of solar panels. The windows and transparent parts under the ceiling of the house are made of high transparency transparent acrylic sheets to ensure the visibility of the internal space.
Base and landscape: the base of the model is a 15mm thick high-density foam board, which is stable and easy to shape the terrain. The lawn is made of environmentally friendly green grass powder and decorated with miniature model shrubs.
3、 Production process: from skeleton to details
The production process follows the order from the inside out, from the whole to the details.
Main framework construction:
Firstly, precisely cut and assemble the basswood plywood into the two-story main structure of the building. The wall corners are spliced at a 45 degree angle to ensure tight and aesthetically pleasing seams. During the bonding process, a large number of right angle fixtures are used to ensure that the building is horizontal and vertical, and the structure is stable.
Installation of exterior walls and detailed components:
Paste the cut off off off off off white ABS board onto the wooden body to create a smooth and even exterior wall effect.
Fine polish the laser engraved reddish brown fence components, remove burrs, and then carefully bond them to the edge of the second layer platform using model specific adhesive. This step requires extreme patience to ensure that all corners are aligned accurately and the pattern remains horizontal.
Paste transparent acrylic board as glass on the inside of the door and window openings.
Construction and installation of photovoltaic ceiling:
This is the technical difficulty of the model. Cut the frosted dark gray acrylic board into a tilted ceiling shape that is completely consistent with the design drawings. The key process lies in how to securely mount it on top of the reddish brown fence. We have pre-set several small transparent acrylic support columns on the inside of the fence, which are almost invisible from most viewing angles, but provide solid mechanical support for the entire ceiling, perfectly reproducing the “floating” effect in the picture.
Scene integration:
After planning the building location on the base, use white glue mixed with gypsum to create slight terrain undulations. Fix the building model to the base, then apply glue to the reserved green area, evenly sprinkle green grass powder, and decorate with miniature shrubs to complete the scene creation.
4、 Post processing and coloring: injecting soul
Post processing is the key to making the model “come to life”, with the core being the representation of the realism of the material.
Color processing:
Main body: The beige wall itself is the original color of ABS board, but we lightly polish it with extremely fine sandpaper and spray a very thin layer of matte protective paint to eliminate the plastic feeling and obtain a texture closer to real paint.
Red brown color scheme: The fence and roof lines are painted using a combination of hand painting and spray painting. First, spray a reddish brown primer, then perform a detailed aging treatment with water-based pigments, and apply a deep brown stain solution to the carved depressions to highlight the three-dimensional effect of the pattern.
Photovoltaic panel: Maintain a matte dark gray tone, but use the “dry sweep” technique, dip a brush in a small amount of silver pigment, and gently sweep it over the surface of the ceiling to simulate the subtle metallic reflection effect of the photovoltaic panel under light.
Texture and Shadow Processing:
Using diluted dark gray pigment as a shadow color, gently depict the areas where windows are recessed into walls, the connection points between ceilings and fences, etc., greatly enhancing the three-dimensional sense and visual depth of the model through contrast between light and dark.
