Noise Barrier for Chillers on Rooftop

Project Overview

KÉSZ, a major player in the Romanian construction industry and Central Eastern Europe, is known for its expertise in building industrial plants, workshops, warehouses, and commercial spaces. During a recent office building project in Bucharest, excessive noise from rooftop cooling units became a concern for the project team. The engineers at KÉSZ sought a reliable solution to address the noise pollution from these units, as it was causing disruptions to nearby workspaces.

DECIBEL was selected to design and install a noise barrier around the chillers to resolve this issue, using our high-performance "PZP" metal perforated panels, renowned for their sound absorption capabilities and rapid delivery times.

Challenge

The rooftop cooling units were generating excessive noise that affected the working environment inside the building, particularly for employees working on the upper floors. The task for DECIBEL was to design an effective enclosure that would reduce the noise levels without disrupting the operation of the chillers or the overall aesthetics of the building.

Scope of Work

• Detailed site analysis of rooftop cooling unit noise
• Design of a custom noise barrier around the refrigeration machines
• Manufacture of "PZP" metal perforated panels
• Quick delivery and installation

Solution

DECIBEL designed a noise barrier using high-performance "PZP" panels. These panels were chosen for their durability and excellent sound absorption qualities. The barrier was custom-fitted around the chillers to ensure maximum soundproofing while maintaining adequate ventilation for the equipment to function efficiently.

Results

The installation of the noise barrier around the cooling units significantly reduced the noise levels affecting the building's upper floors. The quick production and assembly of the panels allowed DECIBEL to meet the tight deadlines, and KÉSZ was highly satisfied with both the noise reduction achieved and the professionalism of the DECIBEL team. This successful project added KÉSZ to our growing list of satisfied clients.

Importance of Soundproofing for Rooftop Equipment

In urban construction projects, rooftop HVAC systems, chillers, and cooling units are common sources of noise that can disrupt both indoor and outdoor environments. Effective soundproofing in these settings ensures that businesses can operate without noise interference, which is particularly crucial for office buildings where concentration and a quiet environment are essential. Additionally, soundproofing solutions must meet local noise regulations, such as the EU Environmental Noise Directive 2002/49/EC, which aims to monitor and manage environmental noise pollution, ensuring both legal compliance and occupant comfort.
