A Case Study in Condensation

...problem for different residential roof systems. Condensation in attics can occur more frequently in the colder climates of the upper Midwest and Northeast and typically on roofs that have inadequate ventilation and insulation, as well as attic bypasses. When dryer vents, bathroom fans or furnace exhaust ducts vent directly into an attic space, the problem is intensified. |[pic] | |Photos courtesy of Wiss, Janey, Elstner | |Associations Inc., Minneapolis. | |Photo 1: Brown stains on the underside of a | |ceiling in one townhouse | Although building codes recommend and require adequate attic ventilation above roof insulation to remove heated air and water vapor that has entered an attic from the surrounding air or a structure's occupied portion, the codes are not strictly adhered to during the design or construction phases. In addition, attic bypasses and openings in dryer vents and furnace ducts must be sealed to minimize moisture infiltration into an attic. This would prevent troublesome condensation within the attic space and on the roof deck's underside. Unfortunately, joints in vents and furnace ducts sometimes are not installed in an airtight manner. The primary signs of severe condensation in an attic space (as viewed from the living spaces) are water stains on ceilings, windows and walls. Such stains generally are the result of melting frost and/or icicles on a roof deck's underside. When staining...

Memo

...Memorandum To: Senior Partner From: Junior associate Re: Robert Langdon Litigation Date: 9th September 2015 ___________________________________________________________________________ Question Presented Robert Landon a construction worker found an old wallet on top of an air duct behind the walls while renovating the second floor of Springfield College of Law. The wallet had $324 dated back to 1972 and no other identification cards. Would Langdon be successful in having the wallet declared to be “lost property” as opposed to “mislaid” and would he be entitled to the money as the finder of the wallet? Brief Answer Robert Langdon will not be successful in having the wallet declared as a lost property and he will have no claim to the money in the wallet. According to the general rule if the property is not found in plain sight and is concealed by some external barrier or there was a substantial effort required to find it, then the property is considered to be mislaid as opposed to lost. This is on the grounds that the owner of the property deliberately hid it in a place where it could not be found easily as opposed to lost property where the owner unintentionally loses his property. In the case of mislaid property, the possession of the property goes to the owner of the premises where it was found. Whereas in the case of lost property, if the property is not claimed by the owner within 12 months, the finder has the claim to the lost property. In this case, the cash was...

Memo 1

...QUESTION PRESENTED Whether a construction worker has a cause of action to declare a found wallet lost property in a situation where the wallet was found sitting on a top of a duct behind a wall where the wallet appears to have been located since 1972 and has not been claimed by its original owner? BRIEF ANSWER No, it not likely that Robert Langdon will succeed in his claim to the money found by him on the top of the duct because of the location where the money was found as well as the manner in which it was concealed. Here, since the wallet was found sitting on a duct, it was likely that the original owner intentionally placed the property in this location for safekeeping, with the intent to later return for it. STATEMENT OF FACTS Plaintiff, Robert Langdon, is a construction worker and an employee for Mason and Mason Construction Company. Currently, Mr. Langdon is working with fifteen other men on the renovation of the second floor at Cleveland-Marshall College of Law. His primary duty consists of plastering the walls of the law school with his fellow co-workers. In August of 2009, Mr. Langdon was working on the walls located in a far back corner of the second floor when he discovered a dusty item sitting on top of a duct that was behind the wall. Upon further inspection, Langdon found that the item was a faded brown leather wallet, which contained $324 but no other forms of identification. The dated currency caused Langdon to believe the wallet had been...

Tel: +8801912669030, E-mail: tanzir68@gmail.com 1 Abstract: The main disadvantage of Electric Vehicle is the lack of capability of storing sufficient energy to run the vehicle for a long time. The energy storage capacity of battery used in electric vehicle is very low compare to conventional fuels used in modern automobiles. The operation, performance and efficiency of motor driven electric vehicles are much better than engine driven vehicles, at the same time electric vehicles are very much environment friendly. Still electric vehicles are falling behind in the automobile industries due to the problem of storage of energy. This paper is based on the concept of charging the batteries of an electric vehicle when it is in motion or propelling. This may be done by using the energy of wind which is caused by the relative motion between the vehicle and the wind surrounding it. Wind turbines can be mounted on the body structure of the vehicle to generate electricity in such a way that it must not create any additional drag force (rather than the existing drag...

CURRENT TRENDS IN LOW-ENERGY HVAC DESIGN Robert L. Tazelaar, PE, LEED AP, robert.tazelaar@arup.com ABSTRACT The objective of this paper is to provide some insight into how HVAC systems are changing to meet the drive towards lower energy usage. The paper is primarily focusing on trends, observed by the author in designs which have been highlighted in research journals and project work. A case study is provided which highlights how some of the trends have been implemented on a current design. KEYWORDS: Heating, Ventilation and Air Conditioning (HVAC), Dedicated Outside Air Systems (DOAS), Ventilation decoupling, Variable Air Volume (VAV) 1.0 INTRODUCTION Throughout the 20th century, trends in HVAC design have been determined largely by technological advances and energy costs. Engineers have always sought to find new ways to ensure occupant comfort, but the level of attention devoted to finding innovative ways to reduce energy use has fluctuated over the last few decades. When energy costs have risen, energy efficiency has become a priority; when they have been low, it has been less of a design driver. This article identifies several trends which are being used to reduce energy use in commercial buildings. The trends to be considered include decoupling of ventilation and heating/cooling, designing...
