Traghella 1 Kaydee Traghella Mclaughlin WRTG 100-10 30 April
Traghella 1 Kaydee Traghella McLaughlin WRTG 100-10 30 April 2013 Green Design: Good for the Planet, Good for One’s Health Reduce, reuse, and recycle. This is a common phrase people hear when it comes to the “going green” movement. However, some people are unsure how to actually incorporate this phrase into their life and see an effect. A great starting point is the home, since it is a place where a majority of people's time is spent. The construction industry focuses on cheap and quick design. It does not take into account where the materials came from, the pollution that is created from the building process, or what happens to the products used at the end of their lives (Choosing Sustainable Materials). Green homes use less resources, energy, and water than conventional homes that were once built (Dennis 93). Many people think about the effects on our planet from building a home, but few think of the harmful health effects new homes can have on one’s body. Although a green home will benefit the planet, a green home can also have health benefits for the occupants living inside it. Lori Dennis, an interior designer and environmentalist, states in her book Green Interior Design, “Green is a term used to describe products or practices that have little or no harmful effects to the environment or human health”(6). The old and traditional ways that homes were built and the way they are still operated now contribute to smog, acid rain, and global warming because those types of homes are still in use (93). -

Low Outgassing Materials
LOW OUTGASSING MATERIALS Low Outgassing Materials GENERAL DESCRIPTION In many critical aerospace and semiconductor applications, low-outgassing materials must be specified in order to prevent contamination in high vacuum environments. Outgassing occurs when a material is placed into a vacuum (very low atmospheric pressure) environment, subjected to heat, and some of the material’s constituents are volatilized (evaporated or “outgassed”). ASTM TEST METHOD E595 Although other agency-specific tests do exist (NASA, ESA, ESTEC), outgassing data for comparison is generally obtained in accordance with ASTM Test Method E595-93, “Total Mass Loss and Collected Volatile Condensable Materials from Outgassing in a Vacuum Environment”. In Test Method E595, the material sample is heated to 125°C for 24 hours while in a vacuum (typically less than 5 x 10-5 torr or 7 x 10-3 Pascal). Specimen mass is measure before and after the test and the difference is expressed as percent total mass loss (TML%). A small cooled plate (at 25°C) is placed in close proximity to the specimen to collect the volatiles by condensation ... this plate is used to determine the percent collected volatile condensable materials (CVCM%). An additional parameter, Water Vapor Regained (WVR%) can also be determined after completion of exposures and measurements for TML and CVCM. ASTM Test Method E595 data is most often used as a screening test for spacecraft materials. Actual surface contamination from the outgassing of materials will, of course, vary with environment and quantity of material used. The criteria of TML < 1.0% and CVCM < 0.1% has been typically used to screen materials from an outgassing standpoint in spaceflight applications. -

The first solution includes the use of Diffusion Pumps (DP’s) for the volume upstream of the Downstream Magnetic Spectrometer (DMS) regions. The second solution uses Turbo Molecular Pumps (TMP’s) for the upstream volume. In each solution, TMP’s are used for each of the four DMS regions. Cryogenic Vacuum Pumping is also considered to supplement the upstream portion of the VVS. The capacity of the Roughing System is reviewed as well. The distribution of the system outgassing is first examined. 2.0 VVS Outgassing Distribution There are several sources of outgassing in the VVS vacuum vessel. These sources are discussed in a previous note [1]. The distribution of the outgassing within the VVS is now considered. The VVS detector total outgassing rate was determined to be 1.0E-2 Torr-L/sec. The upstream portion accounts for 54% of this rate while the downstream side is 46% of the rate. -

An Electron Beam Heated Evaporation Source
An Electron Beam Heated Evaporation Source Martin Magnuson Department of Physics, Uppsala University, Box 530, S-75121 Uppsala, Sweden 1994 Abstract An electron beam evaporator has been assembled, tested and used for deposition of thin nickel films. Flux and deposition rates has been measured with an oscillating quartz crystal monitor (QCM), an ion sensor wire, and visible deposition on a mirror on front of the evaporator. A thin nickel rod of 2 mm diameter was found to improve the pressure in comparison to a 6-mm nickel rod. The flux was typically 3-4 Angstroms per minute during the test, but other flux rates can easily be achieved by changing the filament current and the acceleration voltage. 1. Introduction Electron beam heating is an efficient way of achieving high temperatures when tungsten filament evaporators are not suitable, e.g., when the tungsten filament alloys with the evaporator material. A beam of electrons is produced by a hot tungsten filament. The beam of electrons is accelerated and electrostatically focused to a tip of a metal rod (nickel) held at a high positive potential. The electron beam-creates high temperatures in the source material so that almost any material can be evaporated (melting point of nickel=1453 degrees Celsius). Since the rate of evaporation for materials increases with greater power input, the highest rates are obtained with materials that have low evaporation temperatures and low thermal conductivity. The magnitude of the pressure, which increases during evaporation, depends on the pumping capacity of the system and the cleanliness of the evaporated material. The outgassing of the surrounding surfaces was minimized by water cooling of the surrounding walls. -
Improving Indoor Air Quality with Plant-Based Systems
Improving Indoor Air Quality with Plant-Based Systems By B. C. “Bill” Wolverton, Ph.D. (Ret. NASA) Wolverton Environmental Services, Inc. (WES) Introduction In the United States (U.S.), energy consumption has continually spiraled upward. This increased demand for energy has resulted in energy costs also rising. As a result, the building industry strives to tightly seal buildings to conserve energy. According to the U.S. Department of Energy and the U.S. Green Building Council, commercial and residential buildings account for more than 60 percent of the total electrical consumption in the U.S. When buildings are tightly sealed, a buildup of human bioeffluents, airborne microbes and volatile organic chemicals (VOCs) often leads to poor indoor air quality. In 1989 the U.S. Environmental Protection Agency (EPA) submitted a report to the U.S. Congress on the quality of air found inside energy efficient public buildings. The study included offices, hospitals, nursing homes and schools. This report stated that more than 900 VOCs were identified that may pose serious acute and chronic health problems to individuals who live and work inside these buildings. Even though it is important to reduce energy costs, there are other health-related savings that should be stressed as well. According to studies conducted more than ten years ago at the Lawrence Berkley National Laboratories by Dr. William J. Fisk and Dr. Arthur H. Rosenfeld, companies in the U.S. can save as much as $58 billion annually by preventing sick building illness. An additional $200 billion savings in worker performance could be realized by creating buildings with better indoor air quality. -

Pollution Pods: Can Art Change People's Perception of Climate Change and Air Pollution?
THE VEOLIA INSTITUTE REVIEW - FACTS REPORTS The artwork Pollution Pods is part of the Climart project, POLLUTION a wider research program that looks to explore the ways in which art can change people’s perception of climate PODS: CAN ART change. Before presenting the Pollution Pods project itself, Michael Pinsky describes his process of artistic creation and explains how his work engages with the CHANGE PEOPLE’S challenge of “representing the invisible”. The conception of Pollution Pods is part of a scientific work studying PERCEPTION OF the type of reaction that climate art can bring about in audiences, thinking specifically about the extent to which CLIMATE CHANGE artworks lead people not only to reflect on the reality of their daily lives, but also to alter their behaviour. AND AIR POLLUTION? With Pollution Pods, the artist hopes to disrupt our embodied experience of pollution, which is generally Michal Pinsky, Laura Sommer, that of a background phenomenon to which we grow Artist Researcher at the Norwegian accustomed. To do this, five geodesic domes, five closed University of Science and Technology physical spaces containing toxic air from different cities around the world, are connected, forcing visitors to experience abrupt change in air quality. Pollution Pods is an eminently sensorial experience, whose objective is not so much to offer a privileged audience the thrill of danger safely contained, but rather to push visitors to reflect on their own contradictions and trigger behavioural change, as the embodied knowledge of pollution renders willful ignorance almost intolerable.
