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, 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 …

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 …

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

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 …

Building Hope: A Community + Water Initiative, La Villa De San Francisco, Honduras, Christopher D. Mansfield

Masters Theses

It is my contention that through activating participatory design and community engagement strategies, in conjunction with innovative construction methods that address issues of resource scarcity, the standard of living and level of accessibility to critical resources in impoverished portions of Honduras can be drastically improved. The newly provided model of construction can be done it such a way that it is cost effective in its building method, and provides highly sought after scarce critical resources. This allows participants to allocate more of their finances towards other necessary resources they normally would not be able to acquire.

Benefits Of Personalized Construction Management Software: A Case Study, Mitchell S. Brodnansky

Construction Management

In today’s construction industry, one of the most important aspects of any project, aside from health and safety, is the ability to increase productivity through proper management applications. There are an abundance of programs available to today’s industry (Patterson, 2015); however, some companies are creating their own versions. Many of these programs are tailored to the specific needs of the individual companies. This case study is an in-depth evaluation of personalized construction management software that was implemented by NOVO Construction. It also evaluates the employee preference of personalized software versus software readily available on the market today. The result of …

Case Study: Epoch Estate Wines Production Facility, Kevin Christopher Marx

Architectural Engineering

The project will be a case study performed on Epoch Estate Wines Production Facility in Templeton California. The building is a cut and cover project which was designed to hug the existing oak trees on site. The building serves as a capstone to the Architectural Engineering curriculum because it seamlessly combines the four main structural building materials: steel, concrete, masonry and timber, while also including every lateral force resisting system into one succinct project. During the design of the project, meetings with the architecture of record and client representative occurred where discussion about design procedure and client’s needs took place. …

Case Study: An Effective Model For Green Roofs In San Diego County, Charles Andrews Iii

Construction Management

Green roofs provide a myriad of environmental and financial benefits to a building and its owner. They can provide a pleasing outdoor aesthetic in an urban environment, as well as provide stormwater management and energy savings in an arid climate. California State University San Marcos completed a new University Student Union in 2014 that included a 2,540 square foot Live Roof system on its upper terrace. Supplier, contractor, and facilities team members were interviewed to analyze the success of the project from several viewpoints. The green roof was found to meet the University’s goals on aesthetic design, energy, and stormwater …

Is Zero Net Energy 2020 Actually Attainable, Perceptions Of Various Professionals Effected, Michael Aldridge

Construction Management

California has created a mandate that will require all new residential buildings to become Zero Net Energy by 2020. Some are already doing it others don’t know what it means, and some don’t think it will be possible. Those that already do it are doing it without any extra cost. All that is required is, on average, a 4KW roof solar panel system. This is something that easy to install and only requires a little more planning during the design phase. There are many other things that a designer and builder can do to successfully reach ZNE including focus on …
