Project Overview

 

Building Tuning including the implementation of energy efficient control strategies in the BMS and recommissioning of VAVs and associated Air Handling Systems.

 

A baseline of energy use was established for the period Oct 09 to Sept 10. The baseline was established using a correlation between weather patterns and electricity usage. An estimate of expected energy use (based upon the baseline) has been established for subsequent months and takes into account the weather patterns for each month (Using Cooling Degree Days).

 

The final stage of works were completed in June 2012 therefore only 2 months of energy data is available since the works were completed. The results to date show a consistent reduction of around 15% based upon a comparison of baseline (estimated) and actual. Following the re-commissioning of the Air Handling Systems, the main supply fans were running at a 20% lower speed than previously.
