Conference Papers
Anaerobic digestion processes can generate energy in the form of biogas while treating organic wastewater. The efficiency of the treatment, and thus the generation of biogas, is closely linked to the type and design of the reactor, and the technology used. Granular anaerobic digestion technology offers advantages such as a higher loading rate and reduction of the space needed. However, the hydrodynamics inside this type of reactor can be complex due to the presence of solids (granules) and gas (biogas) phases along with the liquid phase (wastewater). This is one of the reasons why the study and optimization of reactors …

Conference Papers
The addition of a luminescent down-shifting (LDS) layer directly onto a photovoltaic (PV) cell introduces additional loss mechanisms within the system. The combination of non-ideal photo-luminescent materials encapsulated within a limited range of viable host materials, with the increased reflection losses arising from the newly created interface represent losses which must be overcome for LDS to offer an enhancement to the underlying cells efficiency. Exploiting the interaction between the highly enhanced electric fields established close to a metal nanoparticles (MNP’s) surface is one route aimed at mitigating the poor optical properties of the luminophore-host combinations available. Alternative approaches, aimed at …

The Design Of A Modelling, Monitoring And Validation Method For A Solid Wall Structure, Timothy O'Leary, Gillian Menzies, Aidan Duffy
Conference Papers
Hygrothermal assessment is the combined analysis of heat, air and moisture transfer through the building fabric. The two approaches are covered by conventions known as the IS EN 5250:2011 (Glaser method) and IS EN 15026:2007 which differs from Glaser by solving the equations numerically using computer software. Results for hygrothermal analysis provide valuable information for surface and interstitial condensation risk assessment and the impact of energy upgrades. For traditional solid walled structures, conditions such as wind driven rain (WDR) and rising ground water can have a significant impact on the environmental behaviour and in particular the moisture behaviour of the …

A Life Cycle Cost Analysis Of Large-Scale Thermal Energy Storage Technologies For Buildings Using Combined Heat And Power, Kenneth Gaine, Aidan Duffy
A Life Cycle Cost Analysis Of Large-Scale Thermal Energy Storage Technologies For Buildings Using Combined Heat And Power, Kenneth Gaine, Aidan Duffy
Conference Papers
Buildings account for approximately 40% of energy consumption and greenhouse gas (GHG) emissions in developed economies, of which approximately 55% of building energy is used for heating and cooling. The reduction of building-related GHG emissions is a high international policy priority. For this reason and because there are many technical solutions for this, these polices should involve significant improvements in the uptake of small-scale energy efficient (EE) systems. However the widespread deployment of many technologies, must overcome a number of barriers, one of which is a temporal (diurnal or seasonal) mismatch between supply and demand. Costeffective thermal storage solutions have …

Conference Papers
Research studies have shown that the initial energy embodied in a building can be as much as 67% of the operational energy over a 25 year period. With growing global concerns over material and resource consumption and the emissions of CO2 into the atmosphere, the energy embodied in buildings constructed in town and cities becomes important and one of the key issues that needs to be tackled in the design stages in order to strive towards sustainable buildings design. In this paper, a hybrid embodied carbon dioxide equivalent (CO2eq) methodology used to assess the CO2eq embodied in buildings is presented. …
Embodied Energy Analysis: A Sustainable Construction Design Assessment Tool, Adolf Acquaye, Aidan Duffy, Biswajit Basu
Embodied Energy Analysis: A Sustainable Construction Design Assessment Tool, Adolf Acquaye, Aidan Duffy, Biswajit Basu
Conference Papers
Embodied energy analysis can be used as a construction design assessment tool in a sustainable matrix for a building. Its implementation however remains challenging mainly because of data measurement errors. A comparison between the deterministic embodied energy (EE) of a building and the stochastic EE of the same building undertaken using Monte Carlo simulation showed a wide variation in results. It is recommended that the specification of EE intensity of building materials in the construction industry can assist in producing accurate and more credible EE values of building.
The Embodied Transport Energy Analysis Of Imported Wood Pellets, Aidan Duffy, Michael Conroy
The Embodied Transport Energy Analysis Of Imported Wood Pellets, Aidan Duffy, Michael Conroy
Conference Papers
The Irish Government has recently introduced a series of capital grants to boost the uptake of domestic wood-pellet technologies in order to reduce greenhouse gas emissions. These have proved popular and have encouraged a significant number of people to switch from gas- and oil-fired boilers to the cleaner fuel. The demand for wood-pellets has, however, greatly exceeded the national capacity for production. The market for wood pellets elsewhere in Europe is also tight and, consequently, a large proportion of Irish pellets are sourced in Canada. This presents possible problems: the carbon emissions associated with long-distance transport may significantly offset the …
