Energy Case Studies > Monaghan
The Monaghan County Council Office building, located on the Glen Road in the town, was formerly Monaghan Town’s old technical school and was constructed in 1943.
Having undergone a number of modifications over the years, the county offices have been developed in three principal stages and their current layout now forms a quadrangle.
The front or East portion of the building, the extents of which can be identified by its slated façade and roof, is the oldest existing portion of the structure and provides two stories of office space. The original construction of this part of the building was completed during the 1940’s.
The portion of the building to the rear, or west of the courtyard, is a conventional two storey construction and was built in the 1960’s. The two story North and South side wings were added in the 1980’s and completed the closure of the current quadrangle layout forming the internal courtyard. There are approximately 30 offices in the main building of varying sizes on each floor with total floor area of 2155m2.
Air infiltration is an issue had been highlighted by staff as an area that could be improved upon with respect to fuel and energy conservation. This was most likely attributed to the glazing system which consisted of single glazed aluminium windows which, with high thermal-bridging properties which would have a poor level of thermal performance and in their condition, with some failing gaskets and seals, would allow high levels of air infiltration.
The upgrade of the windows would dramatically improve the overall thermal performance of the building fabric and offer much lower levels of air infiltration leading to improved heat retention.
Through the Energy efficiency and Micro Generation project, a thermo-graphic inspection of the County Council offices was undertaken using an infra-red camera. High levels of thermal bridging around the existing single-glazed aluminium windows, as well as and air infiltration above the ceilings were evident during the thermal survey.
The thermal bridging problem, clearly identifiable with the infra-red camera, through conduction, effectively sucks the heat from the building through the aluminium framed windows
To combat heat loss associated with such problems the Energy Efficiency and Micro Generation project replaced the windows with more energy efficient double-glazed uPVC windows. This will improve the building’s heat retention and through a reduction in heating system operation, will significantly reduce thermal energy consumption.
In the Monaghan County Council office exemplar, the upgrade works to the building fabric will significantly reduce heat loss and air infiltration levels associated with the existing aluminium single-glazed windows and drastically improve internal comfort levels for occupants.
Through this fabric upgrade, this exemplar building will demonstrate the effect of more traditional retro-fit works, such as a window upgrade, will have on a building’s heating bills.
Another feature of the exemplar buildings is a visitor experience display screen in the building foyer which, through the monitoring of the building’s energy meters, allows visitors to see a real-time display of the building’s energy performance, comparing live data with historical energy consumption and carbon emissions data.
As part of the Energy Efficiency and Micro-Generation Project works it is anticipated that a target of 22% reduction in energy consumption and 19% reduction in carbon emissions will be achieved.
