An Introduction To Building Contracts: An Irish Context, Tony Cunningham

Other Resources

A contract is an agreement which is capable of being enforced at law and whose essential characteristic is that of a bargain. Contract law focuses predominantly on commercial transactions and in the construction context these range from simple every-day transactions such as purchasing a box of nails to procuring multi-million euro building facilities. In Ireland construction clients typically engage designers and quantity surveyors to formulate designs and they subsequently contract with building contractors to construct the designs. The contractors, in turn, typically outsource much of the work to subcontractors and order materials from numerous suppliers. All of these activities involve …

Influence Of Ground Granulated Blastfurnace Slag On The Thermal Properties Of Pcm-Concrete Composite Panels, Dervilla Niall, Oliver Kinnane, Roger P. West, Sarah Mccormack

Conference papers

The thermal mass of concrete within a building can be used as an energy storage system and hence reduce the demand on the auxiliary heating and cooling systems in the building. The heat storage capacity of concrete can be enhanced by adding phase change materials (PCMs) which provide a high latent heat storage capacity. However the addition of PCM to concrete reduces the conductivity of the concrete due to the low conductivity of the PCMs. This hinders the efficient utilisation of the additional heat storage capacity provided by the PCM.

It is generally understood that the use of ground granulated …

Department of Mechanical and Materials Engineering: Faculty Publications

Abstract Air leakage through recessed lighting fixtures has been identified as a common issue that causes extra energy consumption in residential buildings. However, few quantitative studies in this area were found. As such, a preliminary assessment of the magnitude of this type of energy loss was conducted by using three-dimensional (3D) transient computational fluid dynamics (CFD) models. A hypothetical layout of recessed lighting fixtures was designed with boundary conditions of four different seasons, which were obtained from recorded roof/attic temperature data sets. The results of the study indicate that leakage of recessed lighting fixtures could be a significant channel of …

In Situ Thermal Transmittance Of Case Studies In Dublin., Cormac Flood, Lloyd Scott, Coady Architects

Conference papers

Thermal transmittance (U-values) of exterior walls represent a source of uncertainty when estimating the energy performance of dwellings. It has been noted in research that the standard calculation methodology for thermal transmittance should be improved. Subsequently, hygrothermal analysis has been used as an accurate building design tool due to its incorporation of climate specific effects on construction assemblies such as moisture retention and release. In-situ measurement of thermal transmittance could also be an effective tool for evaluating the material performance of assemblies of a building. This paper provides the context, research process and analysis of 3 case studies situated in …

The Statistical Relevance And Effect Of Assuming Pessimistic Default Overall Thermal Transmittance Coefficients On Dwelling Energy Performance Certification Quality In Ireland, Ciara Ahern, Brian Norton, Bernard Enright

Articles

In the EU, Energy Performance Certificates (EPCs) are issued for dwellings whenever they are constructed, sold or leased. Where requiring data would be prohibitively costly, nationally applicable default-values for the thermal transmittance coefficients of the building envelope are employed. Use of such worst case default U-values ensure that a poor dwelling does not attain a better energy rating than is merited. In the absence of empirical data in Ireland thermal-default U-values, as in many other EU member states, are determined by the type and date of construction and then prevailing building codes. Using 463,582 dwellings representing 32% of the total …

Multidimensional Dialogue Through Architecture | An Exploration Of The Possible Dialogue Between Humans And Walls, Fengqi Li

Architecture Senior Theses

This thesis proposes that architectural design no longer has to be primarily static, but rather it can be dynamically responsive to multiple information streams and conditions.

Multidimensional Dialogue Through Architecture is developed from the understanding of human factors and ergonomics. The dispersed works on research and inference are different ways to explore the interaction between the discipline of architecture and the other fields, such as psychology, engineering, bio-mechanics, physiology, cognitive science, and anthropomorphic.

Subtraction | Construction In Reverse, Sherina S. Zhang

Architecture Senior Theses

The life of a building does not begin at the creation of the new; it starts with the subtraction of the old. As the pace of technological development accelerates, buildings are erected and demolished at an unprecedented rate. Cities use their urban artifacts like skyscrapers, to portray economic and political prowess. For example, the ghost cities of China are relics of a burst financial bubble while Venezuelan ruling party elites name business towers after themselves as a show of power and prosperity. Many parts of the world today are now overbuilt with artifacts that decline into obsolescence. Demolition procedures erase …

A Thermo-Activated Wall For Load Reduction And Supplementary Cooling With Free To Low-Cost Thermal Water, Yuebin Yu, Fuxin Niu, Heinz-Axel Guo, Denchai Woradechjumroen

Durham School of Architectural Engineering and Construction: Faculty Publications

A building envelope serves as a thermal barrier and plays an important role in determining the amount of energy used to achieve a comfortable indoor environment. Conventionally, it is constructed and treated as a passive component in a building thermal energy system. In this article, a novel, mini-tube capillary-network embedded and thermal-water activated building envelope is proposed to turn the passive component into active, therefore broaden the direct utilization of low-grade thermal energy in buildings. With this proposed approach, low-grade thermal water at a medium temperature close to the ambient environment can be potentially utilized to either counterbalance the thermal …
