Impact of source variability on flexibility for demand response
(Elsevier, 2021-08-05)This paper assesses the quality of the services provided for demand response by analysing the results of experimental work activating flexible sources in buildings, while evaluating the impacts on occupant comfort and ... -
Impacts of zeolite, alum and polyaluminium chloride amendments mixed with agricultural wastes on soil column leachate, and CO2 and CH4 emissions.
(Elsevier, 2017-11-02)This study aimed to quantify leaching losses of nitrogen (N), phosphorus (P) and carbon (C), as well as carbon dioxide (CO2) and methane (CH4) emissions from stored slurry and from packed soil columns surface applied with ... -
Implications of applied best management practice for peatland forest harvesting
(Elsevier (ScienceDirect), 2013-12-20)Elevated levels of nutrients and suspended sediment (SS), and changes to other environmental parameters, are frequently associated with forestry harvesting (clearfelling) operations, and are indicative of the potentially ... -
An improved experimental test set-up to study the performance of granular columns
(ASTM International, 2006-03)This paper describes an innovative design of a newly developed large test setup for testing the performance of footings supported on soft clay reinforced with granular columns. This advanced testing method is used to examine ... -
Improving the Delivery of a Construction Management Study-Abroad Course in Ireland through Student Feedback
(2012)International study abroad offers limitless opportunities for students to learn outside of the traditional university setting. By living and learning in a foreign country, the student's exposure to a different culture can ... -
Inactivation efficiency of Bacillus endospores via modified flow-through PUV treatment with comparison to conventional LPUV treatment
(Elsevier, 2018-11-28)Water is a fragile resource, consequently there is a pressing need to develop sustainable environmental-friendly disinfection technologies. This constitutes the first study to compare efficacy of continuous low-pressure ... -
Incidental phosphorus and nitrogen loss from grassland plots receiving chemically amended dairy cattle slurry.
(Elsevier, 2012-09)Chemical amendment of dairy cattle slurry has been shown to effectively reduce incidental phosphorus (P) losses in runoff; however, the effects of amendments on incidental nitrogen (N) losses are not as well documented. ... -
Increasing resource efficiency in wastewater treatment plants: EPA Research Report 168
(Environmental Protection Agency, 2016-03)The focus of this project was the resource efficiency of Irish wastewater treatment plants (WWTPs). The perspective of the report is both operational (economic) and environmental. Wastewater treatment is a resource-intensive ... -
An Indoor Environmental Quality (IEQ) assessment of a partially-retrofitted university building
(Elsevier, 2018-05-07)Achieving standards-based Indoor Environmental Quality (IEQ) in existing buildings is growing steadily due to the strong demand for deep retrofits in Europe. Existing non-domestic buildings pose challenges mainly due to ... -
The influence of age on the timber properties and grading of Scots pine and larch in Ireland
(Oxford University Press, 2023-06-13)Scots pine (Pinus sylvestris L.) and larch (Larix spp.) are two species that could contribute to diversifying Ireland’s timber supply. However, there is little knowledge about their properties as well as their variation ... -
Influence of connection systems on serviceability response of CLT timber flooring
(TU Verlag Wien, 2016-08-22)In this paper finite element analysis of a five layer cross-laminated timber (CLT) rectangular floor is presented. The model was developed using 3D shell elements with linear elastic orthotropic material properties. Support ... -
The influence of crown and stem characteristics on timber quality in softwoods
(Elsevier, 2018-12-28)The relationships between several crown and tree properties and timber quality were examined on three softwood species: Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), Norway spruce (Picea abies (L.) H. Karst) and Sitka ... -
The influence of heat transfer and storage in structural precast building components on indoor environments
(2014)Knowledge about the heat transfer and storage in concrete components of the building envelope is vital in evaluating the environmental and energy performance of buildings. Providing sufficient thermal mass of the building ... -
The influence of panel lay-up on the characteristic bending and rolling shear strength of CLT
(MDPI, 2018-08-21)The objective of this study was to characterise the behaviour of cross laminated timber (CLT) panels and the influence of the panel lay-up on the failure strength. Three different panel configurations of thickness, 60 ... -
Influence of seasonal circulation on flushing of the Irish Sea
(Elsevier ScienceDirect, 2009-12-16)We applied a three-dimensional general ocean and coastal circulation model to the Irish Sea in order to determine water renewal time scales in the region. The model was forced with meteorological data for 1995, a year with ... -
Influence of soil phosphorus status, texture, pH and metal content on the efficacy of amendments to pig slurry in reducing phosphorus losses
(Wiley, 2017-12-13)Cost effective strategies for using chemically amended organic fertilizers need to be developed to minimize nutrient losses in surface and groundwater. Coupling specific soil physical and chemical characteristics with ... -
Infrared thermography technique as an in-situ method of assessing heat loss through thermal bridging
(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 ... -
Installation of a reduced-scale pile group in silt
(IHS BRE Press, 2008)This paper presents measurements of total stress and pore pressure made during and after the installation of a reduced scale group of five piles in a soft estuarine silt. The instrumentation includes pore pressure and ... -
