Newbury Library

AHU mid-life refurbishment


The Issue

Newbury Library approached us to inspect and recommend options for a mid-life AHU upgrade. They wanted to have full connectivity and control from their BMS head end instead of the local controls at the AHU, which was up on a roof and hard to access. They also wanted to extend the lifespan of the unit which was already 15 years old by another 20 years minimum. Any energy savings on top would be a bonus on this project. We were given a specific week to undertake the works and the library had to remain open and operational during the works as it was widely used by the local public.


The Solution

Two new fans were specified by our Service team that could be controlled directly from the BMS and monitored for their energy usage and operational status. We also removed the old internal controls and put in a new controller for the AHU’s heat recovery wheel so that the BMS could optimise its use to recover as much free heating cooling as possible.

We organised a crane to come in and lift the old fans down from the roof and the new ones up at the same time to minimise disruption to the public.


Outcomes

Work was completed ahead of schedule and we also overcame adverse weather conditions (flooding on the roof and thunderstorms) to complete and hand this project over.
