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.

A Financial Impact Assessment Of Ld 1725: Stream Crossings, New England Environmental Finance Center, Muskie School Of Public Service

Water

This report looks at the potential financial impact of LD 1725 on the estimated 30,000 stream crossings in the State of Maine that would be affected by the law. Our research for this report included the analysis of nearly 2000 stream crossings and the data collection necessary for the development of extensive stream crossing replacement cost models. We found that the 1.2 bankfull requirements in LD 1725 would result in a 75% ‐ 250% increase in structure widths for stream crossing projects across the state. An upsize of this magnitude would increase the cost of replacing stream crossings statewide by …

Industry-Experienced Graduate Student Program: Innovative Collaboration In Architectural Engineering At The University Of Nebraska–Lincoln, Clarence E. Waters, Steve Alvine, Michelle L. Eble-Hankins

Durham School of Architectural Engineering and Construction: Faculty Publications

In 2001, the Architectural Engineering Department at the University of Nebraska–Lincoln, along with industry partners, established an industry-experienced graduate student program. The program was developed to bring experienced design professionals to collaborate with the industry while pursuing a Ph.D. in architectural engineering. This program is designed to be mutually beneficial to industry partners, -graduate students, the University of Nebraska–Lincoln Architectural Engineering Department, and the building industry at large. The first doctoral candidate in the program graduated, and significant collaborative work was completed for the industry partner. All parties to this initial offering are pleased with the outcome and believe the …

Material And Energy Flow Analysis Of The Irish Construction Sector, Rachel Woodward

Theses

A national flow model for concrete was developed using the framework of material and energy flow analysis. Using this framework, the Irish concrete material and energy cycles for the year 2007 were constructed by firstly analysing the material life cycle of concrete which consists of the three phases of production (including extraction of raw materials and manufacture of cement), usage into stock (ready-mix and other concrete products), and waste management. In this year, approximately 35Mt of raw materials were extracted to produce both 5Mt of cement and 33Mt of concrete, with 4.5Mt of cement going into the production of concrete. …

Safety And Health Education For Demolition And Reconstruction, Mark Shaurette

Bowen School of Construction Faculty Publications

In the fall semester of 2005, the Department of Building Construction Management (BCM) at Purdue University, located in West Lafayette, Indiana, USA, offered their first course in Demolition and Reconstruction Management. This first college level course developed with input from the demolition industry, offered in the newly created demolition and reconstruction management area of concentration, mirrors many of the general requirements of a traditional construction management curriculum. These include coverage of construction science, planning, regulation, estimating, safety, project management, and business management as they apply to projects that do not begin with a vacant site and a blank sheet of …

The following tables provide a detailed look at the role that culvert material and culvert diameter play in the overall cost of a culvert replacement project.

Culvert Material Cost Comparison, New England Environmental Finance Center

Economics and Finance

The following tables provide a detailed look at the role that culvert material and culvert diameter play in the overall cost of a culvert replacement project. Table 1 displays the cost per foot purchase price arranged by diameter size for the various culvert materials that are currently available. Table 2 displays the average additional culvert pipe material cost (increased cost to upsize minus original in-kind replacement cost) that would be incurred when upsizing a given diameter of culvert with a 50 foot length by factors of: 200%, 250% and 300%.

Top Tips For Domestic Refurbishment, Joseph Little

Articles

1) It stands to reason that insulating a wall should not affect its strength or longevity, nor should it result in a buildup of moisture (inter-stitial condensation) or mould. However the Industry is currently gripped with a desire to insulate to the highest standard (U-value) at the lowest financial cost, as quickly as possible, with little thought of these issues. An appropriate, robust solution must take the original wall, the occupant’s health, the room’s function and even the building’s location into account.

Construction Cost Models, Barry Dikeman

Economics and Finance

The following are a series of cost estimate models similar in format to a typical engineer’s estimate that were developed in support of our financial impact assessment report for LD 1725. The models us current material costs, labor costs, and equipment costs for the region to provide a comparative cost analysis of seven culvert replacement scenarios. The models provide information about what the cost impact of LD 1725 would be for typical culvert replacements in Maine. However, due to the inherent restrictions of the cost modeling framework we were not able to include the abundance of variables that would be …

Increasing Stimulation | Decreasing Progression: The Built Environment’S Impact On Alzheimer’S And Dementia, Tracy Chin

Renée Crown University Honors Thesis Projects - All

With people living longer lives, the population of elderly is increasing at significant rates. Currently 5.3 million suffer from Alzheimer’s in America and 35 million people worldwide. The disease is one that deteriorates brain cells which in turn affects everyday thinking, behavioral problems, and results in a reduced mastery of one’s environment. The current typology is one that has been designed along the same premises of medical institutions and hospitals. The configuration results in narrow corridors and confined, unlit spaces that lead to disorientation and fear—exacerbating both physical and mental symptoms of the disease.

In addition to memory, sensory losses …

Breaking The Mould 5 : Comparative Simulation Of Internal Insulation Systems, Joseph Little

Articles

In the last edition of Construct Ireland ‘Breaking the Mould IV’ established the standard that should be used to evaluate thermal upgrades of single leaf walls, described steps to physically prepare the wall, explained some of the mechanisms that affect the likelihood of mould and gave criteria for judging the simulations outputs. The next step is to simulate a number of permutations of typical internal insulation systems using WUFI Pro under IS EN 15026.
