Case Study: Carlow County Library

/in , /by

Introduction

Carlow County Library is located in the heart of Carlow Town. It is a protected structure and was once a convent. Carlow Library staff have been very proactive in completing energy projects.

Time FrameCarlow County Library

The initial decision to proceed with energy efficiency upgrades took place in April 2014 and the projects were complete by September 2014. The works were funded by SEAI Better Energy Communities 2014.

Implemented Energy Efficiency Measures

Carlow Library opted to install two energy efficiency measures. The first measure they implemented was an upgrade of their lighting. Their existing lighting was T-8, magnetic ballast, mixed with some 2-D fluorescent fixtures. The existing T-8s were replaced with T-5 flourescent tubes and new fixtures and the 2-D fixtures were replaced with LED equivalent. Occupancy sensors were placed in low use areas such as toilets and canteen areas. These were only replaced in the main library section.

In 2013, Carlow Library also upgraded their gas heating system with boiler controls. They kept the existing boiler, but simply added zonal controls, thermostats and timers.
