Building Fabric Design : Thermal Performance Standards, Joseph Little Dec 2012

Building Fabric Design : Thermal Performance Standards, Joseph Little

Articles

This is the first of a series of articles using content from the new RIAI Building Fabric Design CPD which explores a range of themes of central importance to designing buildings that are highly energy efficient, genuinely compliant and perform to their design intent and specification. As the articles are short and the themes are often complex, they can be at best a short introduction to the issues raised. In this article we will look at the new minimum building fabric standards: these are far more onerous than much of the Industry understands.


Bond Between Self-Compacting Concrete And Reinforcement, Marian Sabau, Traian Onet, Ioan Pop Nov 2012

Bond Between Self-Compacting Concrete And Reinforcement, Marian Sabau, Traian Onet, Ioan Pop

Marian Sabau

This paper study the bond behaviour of self-compacting concrete (SCC) in comparison to normal vibrated concrete (NVC). In this paper are presented the following parameters: the influence of bar diameter, the influence of concrete quality, the top-bar effect, the influence of active and passive confinement. In literature, different test results are found for the bond strength in SCC, which deliver contradictory results, but internationally it seems to be agreed that bond strength in SCC is slightly higher than NVC.


Hardened Properties Of Self-Compacting Concrete, Marian Sabau, Traian Onet, Ana Ioana Petean Nov 2012

Hardened Properties Of Self-Compacting Concrete, Marian Sabau, Traian Onet, Ana Ioana Petean

Marian Sabau

This paper presents the properties of hardened self-compacting concrete (SCC) and compare them to those reported for normally vibrated concrete (NVC). The mechanical properties evaluated are: compressive strength, modulus of elasticity, tensile strength, creep, shrinkage and bond with reinforcement. The very wide range of materials and mixes already used for SCC produced a significant scatter of data, but clear conclusions have been obtained. The compressive strength of SCC was likely to be the same or greater than that of NVC by using the same content of cement and water. Modulus of elasticity of SCC was lower than that of NVC …

Building Capability For Disaster Resilience, Lynn Crawford, Craig Langston, Bhishna Bajracharya Oct 2012

Building Capability For Disaster Resilience, Lynn Crawford, Craig Langston, Bhishna Bajracharya

Lynn Crawford

All levels of government recognise the widespread devastation of communities by natural or other disasters. They have responded with emergency management arrangements and policies to enhance government and community capacity to anticipate, withstand and recover from disastrous events. Although the construction industry has a significant role to play, particularly in recovery and reconstruction, it has not generally been considered as a key stakeholder in building capability for disaster resilience. One barrier to more active involvement of the construction industry in disaster response and management is that traditional methods of construction project management have been criticised as too time consuming and …

Lifecycle Energy Consumption Prediction Of Residential Buildings By Incorporating Longitudinal Uncertainties, Endong Wang, Zhigang Shen Oct 2012

Lifecycle Energy Consumption Prediction Of Residential Buildings By Incorporating Longitudinal Uncertainties, Endong Wang, Zhigang Shen

Durham School of Architectural Engineering and Construction: Faculty Publications

Accurate prediction of buildings’ lifecycle energy consumption is a critical part in lifecycle assessment of residential buildings. Longitudinal variations in building conditions, weather conditions and building’s service life can cause significant deviation of the prediction from the real lifecycle energy consumption. The objective is to improve the accuracy of lifecycle energy consumption prediction by properly modelling the longitudinal variations in residential energy consumption model using Markov chain based stochastic approach. A stochastic Markov model considering longitudinal uncertainties in building condition, degree days, and service life is developed: 1) Building’s service life is estimated through Markov deterioration curve derived from actual …


Systemic Rework Risk Classification For Offshore Projects, Peter Love, Jim Smith, Sangwon Han Oct 2012

Systemic Rework Risk Classification For Offshore Projects, Peter Love, Jim Smith, Sangwon Han

Jim Smith

Rework arises due to errors and omissions, and significantly contributes to project cost and schedule overruns in offshore projects. To acquire an understanding of the causal nature of rework in offshore projects, twenty three in-depth interviews with leading oil and gas industry practitioners were undertaken. The dialogue and narratives obtained from the interviews enabled the underlying dynamics of rework to be determined. A risk classification matrix is developed that can be utilized as a frame of reference to mitigate future rework. If rework risks are not given due consideration then there is the potential for latent conditions to become embedded …

Investigating Self-Cooling Effects Of Ventilated Attics Under Different Roof And Ambient Temperatures In Summer, Zhigang Shen, Shimin Wang Sep 2012

Investigating Self-Cooling Effects Of Ventilated Attics Under Different Roof And Ambient Temperatures In Summer, Zhigang Shen, Shimin Wang

Durham School of Architectural Engineering and Construction: Faculty Publications

An unsteady computational fluid dynamics model is employed to simulate summer-time buoyancy-driven turbulent ventilation in gable-roof attics of residential buildings. The energy performance of vented attics is assessed by comparing their performance to sealed attics with the same geometry and insulation configurations. The simulated boundary conditions of the roof-top temperature ranging between 295.15 K and 345.15 K, coupled with an ambient temperature ranging between 295.15 K and 315.15 K, resemble the summer attic conditions with effects of solar irradiance on the roofs. Simulation results indicate that both the vented and sealed attics are dominated by thermal stratification. The cooling load …

Screening And Selecting Project Managers For The Middle East, Sabina Cerimagic, Jim Smith

Jim Smith

Cross-cultural training is of prime importance if the expatriates are to adjust speedily to the new environment and do well in the United Arab Emirates (UAE). Selecting the right people for the overseas job is important as the selected individuals need to have a desire and readiness to learn. Some researchers in this field referred to this as the "learning orientation" where people with high learning orientations like challenges and are ready to learn and people with low learning orientations like to play it safe and do not like challenges. The way the "right" people can be chosen for the …

An Overview Of Component Unit Pricing Theory, David Cattell Feb 2012

An Overview Of Component Unit Pricing Theory, David Cattell

David Cattell

Component unit pricing (CUP) theory presents a fresh approach to item pricing, described as the process of distributing the overall price among its constituent component items. This theory provides explanation and proof that different distributions of mark-up among the items of a project produce different levels of reward for contractors, while exposing them to different degrees of risk. The theory describes the three identified sources of these rewards, namely those of improved cash flow, escalation in compensation and valuations of likely variations. In addition, it also provides the first explanation of the three risks involved, namely the risk of ‘rejection’, …

The Economic Case For Early Adoption Of Facilities Management, Barry Mcauley, Alan V. Hore, Roger West, John Wall

Conference papers

The construction industry in Ireland has been the sector hit the hardest during the recession with a potential return to output volumes of the mid-1990s. In order to compete within this struggling construction sector the traditional way of doing business must be re-engineered. One of the ways to achieve this is by introducing the Facilities Management (FM) process much earlier into the construction process, in order to maximize long term sustainability, and above all whole life construction costs. This paper will focus on a recently constructed sports clinic in Dublin, in which an aggressive programme was introduced around energy management …

The new shelter should incorporate improved natural lighting and ventilation, adequate space for laundry facilities and more space for the animals' living and bathing needs. The design should consider how to prevent dogs from barking and disturbing one another while in the kennels. Increased storage is necessary for the animal shelter to contain the food and living amenities for the incoming animals.
