What are the pros and cons of in situ versus remote weather data for automated control systems?

In situ weather data refers to weather data collected on-site using sensors located on the building or property, while remote weather data refers to weather data collected from a remote location, or online weather service.

Pros of in situ weather data:

1. More accurate data: In situ weather sensors can provide more accurate and precise data about local weather conditions, as they are located in close proximity to the building and can provide real-time data.
2. Better control: In situ weather data can be integrated with automated control systems to provide more precise and responsive control over HVAC systems, lighting, and other building components.
3. Customizable: In situ weather sensors can be customized to meet specific needs and requirements, ensuring that the data collected is tailored to the needs of the building.

Cons of in situ weather data:

1. Higher cost: Installing and maintaining in situ weather sensors can be costly, especially for larger buildings or properties.
2. Limited coverage: In situ weather sensors only provide data for the specific location where they are installed, and may not provide a comprehensive view of weather conditions in the surrounding area.
3. Maintenance requirements: In situ weather sensors require regular maintenance and calibration to ensure that they continue to provide accurate data.

Pros of remote weather data:

1. Lower cost: Remote weather data can be collected from existing weather stations or online sources, reducing the cost of installation and maintenance.
2. Wider coverage: Remote weather data can provide a broader view of weather conditions in the surrounding area, providing a more comprehensive view of local weather patterns.
3. No maintenance requirements: Remote weather data does not require any maintenance or calibration, as it is collected from external sources.

Cons of remote weather data:

1. Less accurate data: Remote weather data may not be as precise or accurate as in situ weather data, as it is collected from a distance and may not reflect local weather conditions accurately.
2. Limited control: Remote weather data may not be integrated with automated control systems, reducing the level of control over HVAC systems, lighting, and other building components.
3. Limited customization: Remote weather data may not be customizable to meet specific needs and requirements, limiting the usefulness of the data for some building owners and managers.

Overall, the choice between in situ and remote weather data for automated control systems will depend on the specific needs and requirements of the building, as well as the cost, maintenance, and accuracy considerations associated with each approach.
