Sustainable energy efficiency retrofits as residential buildings move towards nearly zero energy building (NZEB) standards
(Elsevier, 2020-01-24)
1.9 million housing units in Ireland are required to be retrofitted for the existing Irish national housing stock to be considered nearly zero energy building (nZEB). This paper assesses optimum retrofit packages aimed at ...
Mitigating ammonia and greenhouse gas emissions from stored cattle slurry using agricultural waste, commercially available products and a chemical acidifier.
(Elsevier, 2021-02-05)
Bovine slurry and its subsequent storage are significant sources of ammonia (NH3) and greenhouse gases (GHGs). Chemical acidification of manures has been shown to significantly reduce these emissions. Waste products, derived ...
The role of wet wipes and sanitary towels as a source of white microplastic fibres in the marine environment
(Elsevier, 2020-06-10)
Understanding source elements of the ocean plastic crisis is key to effective pollution reduction management and policy. The ubiquity of microplastic (MP) fibres in the oceans is considered to derive primarily from clothing ...
A statistically based fault detection and diagnosis approach for non-residential building water distribution systems
(Elsevier, 2020-11-01)
Large non-residential buildings can contain complex and often inefficient water distribution systems. As requirements for water increase due to water scarcity and industrialization, it has become increasingly important to ...
Simultaneous adsorption and biodegradation of trichloroethylene occurs in a biochar packed column treating contaminated landfill leachate
(Elsevier, 2021-08-14)
Trichloroethylene (TCE) is a human carcinogen that is commonly found in landfill leachate as a result of anthropogenic activities. Contaminated leachate plumes may be intercepted prior to reaching groundwater and treated ...
Use of non-destructive test methods on Irish hardwood standing trees and small-diameter round timber for prediction of mechanical properties
(Springer Verlag, 2020-06-17)
Key message Mechanical properties of small-diameter round timber from hardwood thinnings of common alder (Alnus glutinosa (L.) Gaertn.), European ash (Fraxinus excelsior L.), European birch (Betula pendula Roth. & Betula ...
Use of rapid small-scale column tests for simultaneous prediction of phosphorus and nitrogen retention in large-scale filters
(Elsevier, 2020-07-01)
Rapid small-scale column tests (RSSCTs) have been previously used to predict the effluent concentration of a single nutrient in large filters with good accuracy. However, in drainage waters originating from heavy textured ...
Strength grading of timber in the UK and Ireland in 2021
(Taylor & Francis, 2022-03-19)
This paper summarises the state of the art for strength grading of construction timber grown in the United Kingdom and the Republic of Ireland. It includes the latest approvals based on recent research on spruce, larch and ...
The relationship between bending and tension strength of Irish and UK spruce and pine
(Springer, 2022-02-07)
The correct characterisation of wood properties is fundamental for the best utilisation of resources. In Europe, grading is defined by strength classes that are determined based on either bending or tension tests. The ...
Operational fatigue loading on tidal turbine blades using computational fluid dynamics
(Elsevier, 2020-01-20)
As the world moves to a greater reliance on renewable energy, a vital component will be the predictability and dependability of the energy source; tidal energy provides such a solution. Horizontal axis tidal turbines are ...
