Application of infrared thermography technique to the thermal assessment of multiple thermal bridges and windows
O'Grady, Małgorzata; Lechowska, Agnieszka A.; Harte, Annette M. (Elsevier, 2018-03-16)A major contribution to the global trend in reducing energy consumption can be made by improving the thermal performance of buildings. Minimization of heat loss via the building envelope is key to maximizing building energy ... -
Detecting the end of nitrification in small and decentralized wastewater treatment systems using low-resource real-time control methods
Fox, S.; Clifford, Eoghan (American Society of Civil Engineers, 2018-06-12)There is increasing demand on operators of small-scale wastewater treatment plants (WWTPs) to improve biological nutrient removal and energy efficiency while being subject to unique challenges, including reduced resources. ... -
Evaluation of the mechanical behaviour of novel latticed LVL-webbed joists
Harte, Annette M.; Baylor, Gordon; O’Ceallaigh, Conan (Bentham Open, 2019-01-23)The mechanical behaviour of a novel I-joist having a latticed Laminated Veneer Lumber (LVL) web is investigated. A total of 30 joists with C24 Grade flanges and latticed LVL webs were manufactured and tested to failure. ... -
An evaluation of the performance and optimization of a new wastewater treatment technology: the air suction flow-biofilm reactor
Forde, P.; Kennelly, Colm; Gerrity, Seán; Collins, Gavin; Clifford, Eoghan (Taylor & Francis, 2014-12-09)In this laboratory study, a novel wastewater treatment technology, the air suction flow-biofilm reactor (ASF-BR) - a sequencing batch biofilm reactor technology with a passive aeration mechanism - was investigated for its ... -
Experimental investigation of the serviceability behaviour of a cross laminated timber floor
Uí Chúláin, Caitríona; Harte, Annette M. (NUI Galway, 2018-08-29)European timber design standards set out basic serviceability limit design criteria for single span, simply supported floors, but the rotational stiffness of the fixing system and two-way support possible with modern solid ... -
Infrared thermography technique as an in-situ method of assessing heat loss through thermal bridging
O’Grady, Małgorzata; Lechowska, Agnieszka A.; Harte, Annette M. (Elsevier, 2016-11-17)A key aspect in assessing the thermal standard of building envelopes is the quantification of the heat loss though thermal bridging, which can be expressed in terms of the linear thermal transmittance Psi. Values of W may ... -
Liquid phase optimisation in a horizontal flow biofilm reactor (HFBR) technology for the removal of methane at low temperatures
Kennelly, Colm; Gerrity, Seán; Collins, Gavin; Clifford, Eoghan (Elsevier, 2014-01-03)Methane (CH4) is a potent greenhouse gas often emitted in low concentrations from waste sector activities. Biological oxidation techniques have the potential to offer effective methods for the remediation of such emissions. ... -
Multiphase numerical modelling of hydraulic structures with rapidly rotating flows: Stormwater vortex hydrodynamic separator
Mullligan, Sean; McDermott, Dermot; Clifford, Eoghan (Conferences and Events at DigitalCommons@USU, 2018-05-15)Hydraulic structures exhibiting strongly rotating flows are widely applied in the field of urban and wastewater hydraulics. Given demographic, urban development and climate change challenge, such infrastructure will require ... -
A novel image processing-based system for turbidity measurement in domestic and industrial wastewater
Mullins, Darragh; Coburn, Derek; Hannon, Louise; Jones, Edward; Clifford, Eoghan; Glavin, Martin (IWA Publishing, 2018-01-19)Wastewater treatment facilities are continually challenged to meet both environmental regulations and reduce running costs (particularly energy and staffing costs). Improving the efficiency of operational monitoring at ... -
Quantification of heat losses through building envelope thermal bridges influenced by wind velocity using the outdoor infrared thermography technique
O'Grady, Małgorzata; Lechowska, Agnieszka A.; Harte, Annette M. (Elsevier, 2017-09-18)Improving the thermal performance of the existing building stock is essential to significantly reduce the overall energy consumption in the building sector. A key objective is the retrofitting of the existing building ... -
A review on building-integrated photovoltaic/thermal systems for green buildings
Şirin, Ceylin; Goggins, Jamie; Hajdukiewicz, Magdalena (Elsevier, 2023-04-25)Space constraints in urban areas can make it difficult to utilise renewable energy resources, like solar energy systems. However, this limitation can be overcome by utilising building façades to produce energy. Up to 40% ... -
Using image processing for determination of settled sludge volume
Mullins, Darragh; Coburn, Derek; Hannon, Louise; Jones, Edward; Clifford, Eoghan; Glavin, Martin (IWA Publishing, 2018-07-12)Determination of the sludge volume index is key to describing the settling characteristics of sludge in the aeration process of wastewater treatment plants (WWTPs). The two core components of this calculation are the settled ... -
Web geometry optimisation of novel latticed LVL-webbed timber I-joists
Harte, Annette M.; Baylor, Gordon; O'Ceallaigh, Conan (Elsevier, 2022-12-02)This paper presents the finite element analysis of novel composite timber I-joists with curved latticed webs. The flanges of the joists were made from Norway Spruce whilst the curved latticed webs were made from laminated ...
