Case Study Of Quantifying Energy Loss Through Ceiling-Attic Recessed Lighting Fixtures Through 3d Numerical Simulation, Ri Na, Shengmao Lin, Zhigang Shen, Linxia Gu

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, William Gleeson

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 …

Value Engineering Of Construction Quantities: "The Golden Report", Chad J. Cornwell

Construction Management

The common materials that are seen everyday on a construction project are concrete, slab dowel baskets and base. Each of these materials can be most seen on highway and road construction. This is often taken for granted since it is in our everyday life. Each of these materials were gathered from a heavy civil project in the greater San Diego area. When collecting my information in the field we gathered existing quantities of concrete, slab dowel baskets, and aggregate. After all of this information is compiled and sent to the project manager hopefully this will result in a decrease in …

A qualitative approach was employed in order to collect and synthesize known factors related to workforce development and capacity building for the construction industry. The paper then presents a conceptual framework for conducting research on capacity generation of a sustainable construction workforce—by considering the impact of family unit and cultural values, career path perceptions, higher educational attainment, and …

Comparing Owner Perceptions Vs. Performance Reality On Construction Management At Risk Public School Projects, Noel Carpenter, Dennis C. Bausman

The Professional Constructor

Over the past decade construction expenditures for education have reached approximately $350 billion with $195 billion of that total spent on K-12 public schools. Public funding through state and local taxes is the primary source of support for construction and school districts are charged with spending these dollars wisely. Within the confines of procurement statutes school districts must select a delivery method that best suits their needs. Two commonly used delivery methods are Design-Bid-Build and Construction Manager at Risk (CM at Risk). This paper examines qualitative and quantitative data collected from one hundred thirty-seven new K-12 school projects constructed in …

Free Fall Of Self-Consolidating Concrete In Walls Three Meters High, Donald J. Phillippi, Katie Loughmiller, Ray Buyle, Michael Cesena

The Professional Constructor

Self-consolidating concrete, (SCC) is a highly flowable, non-segregating concrete that allows for concrete placement without vibration or external consolidation. SCC also allows rapid concrete placement with reduced labor costs, resulting in vastly improved concrete surface finishes and architectural applications (RMCAO 2009). To accomplish SCC, the concrete industry has developed improvements in high-range water reducer admixtures for flowability and viscosity-modifying admixtures for stability. The current project investigated six specimens, which provided an evaluation of SCC allowed to free fall 3 m (10 ft) that filled wall formwork with different inclinations and amounts of steel reinforcement. The purpose of the investigation was …

International Construction Measurement Standards (Icms) Explained, Charles Mitchell

Articles

In 2015 the United Nations wrote to various construction cost bodies around the world seeking some form of uniformity in the reporting of construction costs worldwide. The UN concern was the variance of reported statistics globally for similar projects even when local economic factors were taken into account.

As a result a meeting was held for interested parties in the offices of the International Monetary Fund (IMF) in Washington D.C. in May 2015. This meeting became the inaugural meeting of what, today, is known as the International Construction Measurement Standards (ICMS) Coalition. The membership of the coalition is open to …

Measuring Building Substructures: Solutions To ‘First Year’ Introductory Level Examination Questions, Tony Cunningham

Other Resources

The measurement of substructure works to simple domestic type buildings is a logical starting point for students to commence the process of taking-off building quantities. Substructure work is typically the first class of work to be explained in textbooks dealing with both construction technology and building measurement. However, substructure work is often one of the most challenging elements to measure. In this paper, the author demonstrates the process of measuring basic substructure designs. The approach involves providing solutions to a sample of four Irish Department of Education Technological Certificate: Builders’ Quantities Intermediate Stage examinations. The intention is to demonstrate how …

Mechanical And Thermal Evaluation Of Different Types Of Pcm-Concrete Composite Panels, Dervilla Niall, Oliver Kinnane, Roger West, Sarah Mccormack

Conference papers

ABSTRACT: Thermal mass indicates the ability of a material to store and release heat and is a function of the heat storage capacity of a material. The thermal mass of construction materials can be used to reduce the energy required for heating and cooling buildings. The heat storage capacity of concrete can be increased by incorporating phase change materials (PCMs) into the concrete and hence providing additional latent heat storage capacity. Research was carried out to compare the thermal behaviour of two different types of PCM/concrete composite panels. The first type of panel was formed by adding microencapsulated paraffin to …

The Role Of The Contract Administrator Under The Principal Irish Standard Forms Of Building Contract, Tony Cunningham

Other Resources

Construction contract administration concerns the effective execution of construction contracts. The primary objectives of the individual appointed to administer a building contract typically include delivering the project safely, to the specified quality standards, on time, and within the employer’s budgetary constraints. The administrator’s task is to orchestrate and motivate the various designers and constructors to deliver the best possible performance both individually and as members of the team. This study has investigates the contribution made by the contract administrator in administering construction projects and outlines the decision-making, advisory and information roles undertaken by the contract administrator in the context of …
