St. Mary And St. Anne Cathedral, Cork: An Optimum Heating Solution For Heritage Buildings?, Christopher Shiell, Roger P. West

Civil Engineering Research in Ireland 2020

Cathedrals and most churches are characterised by having large internal, undivided spaces and permeable building envelopes. They are often used little, intermittently, but predictably and, in spite of the fact that they are unique in still being largely used for the purpose for which they were built many centuries ago, they are now often used for additional purposes, for which they were never designed. These uses include concerts, graduation ceremonies, filming and a host of other uses all of which require a level of thermal comfort not envisaged by the original builders. Research was undertaken by the authors into the …

Challenges And Opportunities To Deep Retrofitting Of Traditional Fabric Buildings To Achieve Nearly Zero Energy Building (Nzeb), Maria Lopez Zambrano, Paul Kenny, Jamie Goggins

Civil Engineering Research in Ireland 2020

Many of our traditional buildings are disappearing or in danger of being under utilised because they are not comfortable for modern day living and do not meet our present day needs. If a building does not have a use, inevitably it deteriorates and eventually becomes a ruin or gets demolished. It is important to retrofit these buildings, which are part of our identity and can be powerful tourist attractions even though most of them are not listed. Some owners want to apply for retrofitting schemes and grants, but they are rejected because there are no standard solutions to achieve low …

Can Deap Help Us To Predict The Energy Demand And Indoor Temperature Of Homes Before And After Renovation? A Case Study From Dublin, Paul Moran, Jamie Goggins

Civil Engineering Research in Ireland 2020

Improving the energy efficiency of buildings via retrofitting is seen as one of the key mitigation measures to reducing the energy demand and carbon emissions of the built environment in Ireland. However, while energy efficiency retrofits for buildings are effective in theory, the energy savings estimated by statistical or engineering models can often be inaccurate. The Domestic Energy Assessment Procedure (DEAP) is the standard assessment procedure used for assessing the energy performance standard of residential buildings in Ireland. This paper examines the gas energy demand for space and water heating and the internal temperature profiles in contrast to DEAP estimates …

Operational And Embodied Energy Analysis Of 8 Single-Occupant Dwellings Retrofit To Nzeb Standard, Richard O'Hegarty, Shane Colclough, Oliver Kinnane, Donal Lennon, Etienne Rieux

Civil Engineering Research in Ireland 2020

In line with the Energy Performance of Buildings Directive, Irish dwellings are being retrofit to near Zero Energy Building (nZEB) standards - with a number of the deep energy retrofits classified as A-rated. As a result of the low operational energy, the embodied energy share of an nZEB's life cycle energy is significantly increased. Therefore, to obtain a holistic picture of the change in energy profile of buildings, the embodied energy of the material added to achieve that low performance should also be taken into account. This paper presents results from a case study of 8 single-occupant terrace bungalows retrofit …
