Any device that supports heating, cooling, or waste management, as well as water supply and electricity, can be considered mechanical equipment. This equipment includes compressors and chillers as well as HVAC, compactors or breakers, meters, generators, and containers. This equipment is located on a roof and is therefore more susceptible to wind damage. It is also often in the direct line of sight for pedestrians.
A building permit is required for the rooftop screening of mechanical equipment. You will need to get community approval for the equipment to be able to match the area and building envelope. For more information, contact your local building inspector and city planning office. An architect will provide drawings to accompany a building permit. These drawings must comply with the guidelines and appearance standards of the community for rooftop mechanical screening. To ensure that material selections are consistent with the community’s design, as well as the surrounding buildings and public view considerations, the community should create guidelines.
For rooftop-mounted equipment screens, consider the following:
Material And Scale Of The Building Envelope: The rooftop equipment screening should be compatible with the existing structure, colours, and style. Example: Vertical slats/vertical louvers are recommended for roofs with vertical lines.
Line Of Sight: When designing a rooftop equipment screen, consider how you can see the screen from every possible vantage point. If equipment isn’t visible from any location, screening might not be required. Equipment might need protection in this situation. You should also consider the wind load. A rooftop screen with a roof or overhang might be regarded as if the building is located near an elevated structure or road. This matter can be discussed with your local code.
The Mechanical Equipment Being Screened: You should consider the equipment’s use when designing roof-mounted screening equipment. Screening rooftop equipment is not always possible due to space limitations and height restrictions. The equipment might need to be painted to conform to local aesthetic standards. Some stacks must reach the recommended ventilation heights. These stacks may need to be framed with materials that match the building envelope.
Structural Considerations: To calculate wind load, it is necessary to consider the project’s location. A set of stamped drawings and performance data can be provided by structural engineering to calculate wind loads.
Visibility Can Be Either Good Or Bad: Rooftop mechanical equipment screening could be modified to attain the visibility required by local codes. The louvered panel is the most popular roof-mounted screen for mechanical equipment. This design allows for visual screening of up to 80% from a direct view.
Degree Of Openness: This directly relates to visibility and direct visual screening. The degree of openness is determined by the distance between holes and louvers. The distance between infill elements determines the airflow. The maximum space allowed for rooftop mechanical equipment is usually limited to a certain amount. Community guidelines might be required to ensure adequate airflow.
Infill Design And Selection: To meet community appearance standards, there are many options for screening rooftop mechanical equipment.
This information will assist you in assessing the requirements of your mechanical equipment screen. The next step is to determine the best materials and products for creating their rooftop mechanical equipment screens.
