There are several ways that a parking garage design can incorporate exterior shading devices to reduce solar heat gain. Here are some examples:
1. Overhead Canopies: Install large overhead canopies or pergolas that provide shade over the parking spaces. These can be designed with materials that reflect sunlight and reduce heat absorption.
2. Vertical Louvers or Fins: Attach vertical louvers or fins to the exterior walls of the parking garage. These can be adjustable or fixed structures that block direct sunlight while allowing natural light and air circulation. Louvers can be made of materials like metal, wood, or composites.
3. Light Shelves: Install horizontal light shelves along the outside walls, particularly on the upper levels of the parking garage. These shelves can act as horizontal louvers, blocking the high-angle sunlight during peak periods and reducing solar heat gain.
4. Perforated Screens: Use perforated metal screens on the outer walls or facade of the garage. These screens allow for airflow and visibility while reducing direct sunlight exposure. The perforations can be designed in various patterns to achieve the desired shade and aesthetic effect.
5. Trellises and Green Walls: Incorporate trellises and green walls covered with climbing plants or vines. The plants provide natural shading and can significantly reduce the solar heat gain. Additionally, the greenery improves the aesthetics and air quality around the parking garage.
6. Photovoltaic Panels: Combine shading devices with photovoltaic panels or solar shading systems. These panels generate electricity while providing shade, helping to offset energy consumption and reduce heat gain.
7. Design Orientation: If possible, align the parking garage to minimize direct sun exposure. By orienting it in a way that avoids the harsh sun angles, especially during peak heat hours, it would naturally reduce solar heat gain without the need for additional shading devices.
These shading devices can be combined or customized based on the specific requirements of the parking garage design and climatic conditions of the location.
