Case Study
Sick Building Upgrade
Overview
Project Overview: An existing building required modifications to meet healthy standards. The first phase of the project involved increasing the fresh air intake based on test results, which indicated the necessity for electronic air cleaners and a UV-C lighting system. These enhancements were essential to improving the building's air quality and ensuring compliance with health standards.
An existing building required modifications to meet healthy standards. The first phase involved increasing fresh air intake based on test results, which indicated the need for electronic air cleaners and a UV-C lighting system.
Background
An existing building required modification to bring the building up to healthy standards.
Objectives
In doing so the first phase was a need to increase the fresh air based on test results which indicated the needs for electronic air cleaners and a UV-C lighting system.
Solutions
The current Hymist system is inadequate and needs removing. Bespoke framing was required to take the UV-c Lighting system and new fresh air intake ductwork was incorporated. Bag filters were removed to enable manufacture of suitable support system so the electronic air cleaners could be accommodated.
Analysis
Following installation, the airflows needed rebalancing to ensure correct airflows for the spaces and to prevent overheating of the new electronic filter sections and UV-C lighting system. The manufacturer of the electronic components commissioned the system they developed.
Installation
Restrictions of working inside the existing AHU’s to get the new equipment in and incorporating the additional fresh air control requirements created a number of challenges in both access and mounting.
The new equipment installed couldn’t allow bypassing of air and built in sections suitable to be assembled once placed in position inside the AHU’s.
Conclusion
The installation of new equipment inside the existing AHUs presented significant challenges due to restricted access and the need to incorporate additional fresh air control requirements. The equipment was designed to prevent air bypass and was assembled in sections once inside the AHUs. Post-installation, the airflows required rebalancing to ensure proper distribution and prevent overheating of the new electronic filter sections and UV-C lighting system. The manufacturer of the electronic components subsequently commissioned the system, ensuring its optimal performance.
