An Indoor Environmental Quality (IEQ) assessment of a partially-retrofitted university building
Zuhaib, Sheikh; Manton, Richard; Griffin, Corey; Hajdukiewicz, Magdalena; Keane, Marcus M.; Goggins, Jamie (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 heat transfer and storage in structural precast building components on indoor environments
Hajdukiewicz, Magdalena; Goggins, Jamie (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 ... -
Lifecycle environmental and economic performance of nearly zero energy buildings (NZEB) in Ireland
Goggins, Jamie; Moran, Paul; Armstrong, Alan; Hajdukiewicz, Magdalena (Elsevier, 2016-01-16)Directives in the European Union are ensuring that buildings in this region are moving towards nearly zero energy buildings (NZEB). For countries like Ireland, which has a temperate oceanic climate, a key to achieving NZEB ... -
Methodology for quality checks for energy efficient buildings
Hajdukiewicz, Magdalena; Goggins, Jamie; Keane, Marcus M. (NUI Galway, 2017-03-01)The built environment accounts for more than 40% of the overall energy consumption and 36% of the overall CO2 emissions in Europe. Moreover, statistics show that construction and the upkeep of European buildings and ... -
A novel BIM-based process workflow for building retrofit
D'Angelo, Letizia; Hajdukiewicz, Magdalena; Seri, Federico; Keane, Marcus M. (Elsevier, 2022-02-06)The European Union (EU) has developed policies aimed at accelerating the retrofit of existing buildings, with the vision of a decarbonised building stock by 2050. Retrofitting of existing buildings offers significant ... -
A novel reduced order model technology framework to support the estimation of the energy savings in building retrofits
Piccinini, Alessandro; Hajdukiewicz, Magdalena; Keane, Marcus M. (Elsevier, 2021-03-13)Energy Performance Contracting (EPC), as a tool to enhance energy efficiency of buildings, can accelerate investment in cost-effective energy conservation measures (ECMs) for existing buildings. However, there are many ... -
A novel ROM methodology to support the estimation of the energy savings under the Measurement and Verification protocol
Piccinini, Alessandro; Hajdukiewicz, Magdalena; D'Angelo, Letizia; Blanes, Luis M.; Keane, Marcus M. (National University of Ireland Galway, 2020-09-21)This paper presents a novel Reduced Order grey box Model (ROM) methodology, based on a ResistorCapacitor (RC) network, which supports the creation of the baseline energy consumption and the estimation of energy savings ... -
Real-time control of occupants thermal comfort in buildings
Hajdukiewicz, Magdalena; O'Connor, Padraig; O'Neill, Colin; Coakley, Daniel; Keane, Marcus M.; Clifford, Eoghan (International Building Performance Simulation Association, 2015-12-07)Providing satisfactory indoor environmental conditions, air quality and thermal comfort through adequate ventilation is crucial in maintaining safe, healthy and comfortable buildings. Since, heating, ventilation and air ... -
Real-time monitoring framework to investigate the environmental and structural performance of buildings
Hajdukiewicz, Magdalena; Byrne, David; Keane, Marcus M.; Goggins, Jamie (Elsevier ScienceDirect, 2014-12-20)Energy provides safety, comfort and mobility to people, and is essential for industrial, commercial and societal growth. However, generation and consumption of energy give rise of greenhouse gases and various air pollutants, ... -
Real-time monitoring of a hybrid precast and in situ concrete flat slab system
Goggins, Jamie; Newell, S; King, D; Hajdukiewicz, Magdalena (2014)This paper presents a scheme developed for instrumentation and monitoring of the structural performance of a hybrid precast and in situ concrete flat slab system employed in an educational building. The system contains a ... -
Real-time monitoring to investigate structural performance of hybrid precast concrete educational buildings
Newell, Shane; Goggins, Jamie; Hajdukiewicz, Magdalena (Taylor & Francis, 2016-11-22)The motivation and implementation of a real-time structural health monitoring strategy to determine the structural performance of a number of educational buildings recently constructed in Ireland is discussed in this paper. ... -
Retrofit solutions for Irish building stock: The impact of human behaviour
Moran, Paul; Goggins, Jamie; Hajdukiewicz, Magdalena; Rau, Henrike (NUI Galway, 2016)Retrofitting buildings is recognised as the most immediate, pressing, and cost effective mechanism to reduce energy consumption and carbon emissions in the building and construction sector. It is necessary to double or ... -
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% ... -
