Through 2009, 663 college and university presidents had signed the American College & University Presidents' Climate Commitment (ACUPCC) (www.presidentsclimate commitment.org), pledging 'to eliminate net greenhouse-gas emissions from specified campus operations [...]

With ever-increasing pressure to design for lower space temperatures and relative humidities, engineers are providing colder, drier supply-air streams requiring deeper cooling coils and lower chilled-water temperatures for health-care and [...]

This (From the Editor, December 2005, 'The O&M Conundrum') was another good and thought-provoking editorial, Mike. This is only the second time I have responded to an editorial in a [...]

Extended-surface air-cooling coils are critical components of modern airconditioning systems. Of those requiring custom selection and specification, the chilled-water cooling coil is by far the most common. First and foremost, [...]

Last month, we learned that, in a typical duct system, the temperature of an air stream undergoing frictional and dynamic losses does not change. What's more, we learned that, in [...]

The "environmental justice" movement was born of the recognition that poor people and racial minorities encounter environmental hazards particular to their immediate surroundings. (1) African-American children face significantly higher rates [...]

Air-duct systems are of vital importance to most modern HVAC systems, often representing 20 percent or more of installed HVAC-system cost and playing a key role in building occupants' perception [...]

The fan industry is a nature industry based on technology that is, for the most part, not new. The basic fluid mechanics governing fan aerodynamic design and performance have been [...]

One of the fundamental concepts that apply to air systems is the fluid mechanics of conveying air. This article presents the basic principles that form the groundwork for the design, [...]

In his review of Icons of Hope (1/6), Thomas P. Rausch, S.J., points out that both Pope Benedict and John E. Thiel, the book's author, 'reject the idea of resurrection [...]

Robert B. Blake and Deborah Anne Carroll have created a scientific model for ethical decision-making for business people based on Kohlberg's three levels and six stages of human development. The model is flawed on two accounts: Kohlberg's research excluded women; and the model relies too much on psychology. The authors preclude philosophical grounds for ethical decision making and rely on mature people's predilection to act on universal, altruistic principles. Psychological grounds of conduct do not readily translate into grounds that lead to proper and consistent moral conduct. Moral philosophy is superior to psychology in that it: delineates the grounds for ethical decision making; justifies when a person should and should not act; and provides principle why one act is preferable to another., More on Ethical Reasoning in Business A philosophical model for making moral decisions is still the soundest approach to ethical reasoning in business, says this author, despite a recent Journal [...]

Cathleen Kaveny, in her column 'A First Step?' (January 14), correctly points out that a couple having sex while the woman is taking the birth-control pill to regulate a serious [...]

I just read the article by Gerald J. Williams, PE, LEED AP, about wet filters on a blow-through air-conditioning system ('The Case of the Wet Filters,' April) and found it [...]

Regarding 'Schiavo autopsy points up need for end-of-life discussions' by Patricia LeFevere and Robert McClory (NCR, July 1): Yes, we do need such discussions--conducted with understanding and reasonableness, especially by [...]

The article discusses why mentoring is important in the field of heating ventilation and air conditioning (HVAC) engineering. Topics covered include the author's experience of being mentored by William J. Coad when he took up an HVAC course in 1970, the qualities, teaching strategies and beliefs of Coad, and the author's assertion that mentoring not only impart knowledge, but also insight and perspective.

A letter to the editor is presented about the removal of feeding tube from Terri Schiavo, a patient who is in persistent vegetative state.

Presents letters to the editor referencing articles and topics discussed in previous issues related to heat engineering, plumbing and air conditioning. "The O&M Conundrum," which addressed the operation and maintenance heating, ventilation and air conditioning systems, in the December 2005 issue.
