Embodied Emissions Abatement: A Policy Assessment Using Stochastic Analysis, Adolf Acquaye, Aidan Duffy, Biswajit Basu
Embodied Emissions Abatement: A Policy Assessment Using Stochastic Analysis, Adolf Acquaye, Aidan Duffy, Biswajit Basu
Articles
Policymakers traditionally focus on regulating operational energy use in buildings, ignoring other life cycle components such as embodied energy even though this may account for a significant portion of life cycle emissions. Data relating to embodied energy and emissions in buildings is limited. However, stochastic techniques can be used to estimate the distribution of such emissions from buildings. This helps policymakers identify which instruments are appropriate for achieving emissions reductions. A primary aim of this paper is to demonstrate this approach using a sample of apartment buildings in Ireland. A Monte-Carlo simulation suggests that the average probability distribution of embodied …

BIM is having a profound effect worldwide on the construction industry. …
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 …

The Relevance Of Teaching Traditional Measurement Techniques To Undergraduate Quantity Surveying Students., Fiacra P. Mcdonnell
Articles
Measurement of quantities is a core skill which must be inherent in all graduates from Quantity Surveying courses. Many students find this subject difficult to grasp, and the learning experience can be problematic especially in the first semester of first year. This is not unique to measurement as in many cases first year students are in the process of adapting to a new stage in their life, along with attempting to master many new subjects (Cottrell, 2008). This is reinforced by Johnston (2010) who highlights the many challenges being experienced by first year students and observes that “ entering first …
Input-Output Analysis Of Irish Construction Sector Greenhouse Gas Emissions, Adolf Acquaye, Aidan Duffy
Input-Output Analysis Of Irish Construction Sector Greenhouse Gas Emissions, Adolf Acquaye, Aidan Duffy
Articles
Ireland is committed to limiting its greenhouse gas (GHG) emissions to 113% of 1990 levels over the period 2008-12 and to 84% of 2005 levels by 2020 under the Kyoto Agreement and the EU’s ’20 20’ by 2020 respectively. National policies have targeted many industry sectors but have failed to directly tackle GHG emissions associated with construction activity. This paper estimates energy and GHG emissions intensities of the Irish construction sector and subsectors and estimates its contribution to Irish national emissions. This information is used to identify and assess the impacts of policy measures which would result in a reduction …

Comparison Of Indian Ppp Construction Industry And European Ppp Construction Industry: Process, Thresholds And Implementation, Louis Gunnigan, Renuka Rajput
Conference papers
Abstract Since the 1990’s, there has been a rapid rise of Public Private Partnerships (PPPs) across the world. Governments in developing as well as developed countries are increasingly using this procurement method to bridge the much needed infrastructure gap. PPPs are seen as an important tool for producing an accelerated and larger pipeline of infrastructure investments, and catching up with the infrastructure deficit. Arguably, this is why developed and especially developing countries are very keen on PPP models. This paper will compare the PPP procurement process followed in Europe compared to India and presents a thorough review of literature on …

Finding A Middleware Ict Solution For The Irish Construction Sme Sector, Alan V. Hore, Alan Redmond, Roger West
Conference papers
A key feature of the Irish construction industry is its fragmented structure. Some 16,000 businesses list their main activity as construction, yet no company has more than 3% of the total Irish output. The top 20 companies have less than 15% of total output. There is a very high number of Small to Medium Sized Enterprises (SME‟s) in the sector. However, most software products which address the specific needs of the construction industry are designed for larger companies. It is felt that the needs of the large number of SME‟s in the sector are underserved. The Construction IT Alliance (CITA) …

Building Support For Coud Computing In The Irish Construction Industry, Alan Redmond, Alan V. Hore, Roger West
Conference papers
The construction industry has been traditionally recognised as a fragmented sector associated with a poor level of implementation and penetration of Information Communication Technology (ICT) by Small to Medium Size Enterprises (SMEs). Cloud computing is a collective term that can facilitate the ability to collaborate within a central repository that can act as a base for interoperability between various construction disciplines and their software applications. Cloud computing is a new layer of internet architecture that creates an open opportunity to add better functionality to an increasingly global network. The characteristics of cloud computing, such as, shared infrastructure, on-demand applications, elasticity …

Thermal Testing Of Innovative Building Insulations, Eoghan Frawley
Masters
The main objective of this research was to design and develop a Hot Box to test the thermal properties of Eco-quilt multi-foil insulation. This work began by gaining an understanding into how multi-foil works, how it is installed and examining different variations of this insulation. It was clear at an early stage that there were two conflicting opinions on the thermal performance of multi-foils. One set of tests claimed that the insulation had a thermal resistance of approximately 5 m2oC/W. These tests were carried out in real weather conditions, where temperatures were fluctuating, although one laboratory test achieved similar results. …
