Stochastic Hybrid Embodied Co2-Eq Analysis: An Application To The Irish Apartment Building Sector, Adolf Acquaye, Aidan Duffy, Biswajit Basu Apr 2011

Stochastic Hybrid Embodied Co2-Eq Analysis: An Application To The Irish Apartment Building Sector, Adolf Acquaye, Aidan Duffy, Biswajit Basu

Articles

Although embodiedCO2-eq analysis has seen recent developments as evident in the establishment of the ISO14040 and 14044 LCA standards, it is recognized that due to weaknesses in gathering data on product-related emissions,embodiedCO2-eq values are probabilistic. This paper presents a stochastic analysis of hybrid embodied CO2-eq in buildings to account for this weakness in traditional methods and, by way of example, applies it to an Irish construction-sector case study. Using seven apartment buildings, 70,000 results are simulated with Monte Carlo analysis and used to derive probabilistic and cumulative embodied CO2-eq intensity distributions for apartment buildings in Ireland. A Wakeby distribution with …


Thermal Bridging - Understanding Its Critical Role In Energy Efficiency, Joseph Little, Beñat Arregi Mar 2011

Thermal Bridging - Understanding Its Critical Role In Energy Efficiency, Joseph Little, Beñat Arregi

Articles

Plane element heat loss[1] and thermal bridging[2] together constitute all the conduction heat loss (measured in W/K, watts per kelvin) through the thermal envelope[3] of a building. Perversely insulating the plane elements more and more without carefully dealing with junctions can lead to a significant increase in thermal bridging heat loss. This is often more significant in poorly thought-out energy-focused retrofits than in existing or new buildings.


Scsi Guide To Life Cycle Costing, Dermot Kehily Jan 2011

Scsi Guide To Life Cycle Costing, Dermot Kehily

Reports

This document provides practical guidance and assistance for construction cost professionals in carrying out Life Cycle Cost

Analysis (LCCA) and producing Life Cycle Cost Models (LCCM). The document puts forward a number of definitions of Life Cycle

Costing (LCC), outlines how LCC calculations can be carried out and proposes a structure and methodology for presenting LCCM.

Crossings, Noel Brady

Books/Book Chapters

Chapter concentrates on the bridges of Dublin’s river Liffey; their importance to the vitality of the city, its commerce and people. It also highlights the importance of crossings in the city linking and opening up new paths to growth and development.
