Granite State Chapter of ASHRAE
Meeting Notice
September 20th, 2018



Just a quick note that we will be hosting our annual Granite State ASHRAE Golf Tournament on Thursday September 20 at the Candia Woods Golf Links located at 313 South Road in Candia.

As you may be aware, the annual gold tournament is a major fund raiser for the local ASHRAE chapter and we would appreciate your support. There will be corporate sponsorship opportunities, team sponsorships, as well as individual sponsorship opportunities even if you choose not to play. So please take a moment to make a note of the day and time, and plan to participate in this years event. It's a great opportunity to support your local ASHRAE chapter while having some fun with your colleagues and friends. Proceeds from this event support the ASHRAE Research Promotion efforts as well as the ASHRAE Scholarship Program.

We will be reaching out again over the summer to provide more details, but for now, please just "Save the Date" of Thursday September 20 for a day of fun with us at the Candia Woods Golf Links.

Press Release
April 12th, 2018


Legionella is still a health threat and building designers, owners and operators may be libel for illness and death of occupants if they fail to follow applicable standards and codes. This was the most important take away from the presentation by Paul Jappe at Viega’s training center in Nashua. Although rarely reported in the news, 120,000 people have died in the US from Legionnaire’s illness since the original identification of the aerobic bacteria as the cause of deaths at an American Legion convention in Philadelphia in 1976. 



Although reports have said that the source of Legionella bacteria was cooling coil drip pans (Philadelphia) and cooling towers (Brooklyn), the primary breeding ground of Legionella is plumbing. Stagnant water in plumbing systems of traditional branch and tee designs, creating dead legs, and failure to perform regular purges of inactive plumbing services is the primary source of the bacteria. Additionally, with modern day, low-flow fixtures combined with over sized piping can cause low velocities in the pipes thus aiding the start of bio-film formation and harbor the Legionella bacteria. But Legionella must be inhaled. It can’t be contracted by drinking contaminated water or personal contact with infected individuals. So, contaminated water must be atomized in, for example, showers, indoor decorative fountains, vaporizers and atomizers used to cool people in hot spaces/areas or used to reduce static discharge in fabric and paper mills. And Legionella can survive at temperatures between 68 F and 120 F and with temperatures between 95 F and 115 F creating the best conditions for growth. ASHRAE standard 188 and Guidance No. 12, section 4.1.6 suggests ways to design, build and operate plumbing systems to prevent the growth of Legionella. And proper maintenance procedures are spelled out in to control the growth of Legionella. Failure to follow the specified design/construction and maintenance procedures to mitigate the growth of Legionella could lead to an outbreak of this infection, often misdiagnosed as pneumonia, and expose the parties involved to legal consequences.

Press Release
December 6th, 2017
 
The Granite State Chapter of ASHRAE and Chapter 140 of the Association for Facilities Engineering held their annual joint meeting at Veiga’s Training Center in Nashua on December 6th. Over fifty members and guests attended the combined vendor show and technical presentations. Thirteen vendors had table top displays where people could learn more about their products and services and there were three, 45 minute technical presentations that included representatives from the State’s Department of Environmental Services and two industry spoke persons. See below for details. The event included a buffet dinner provided by Veiga.

           



 

Vendors: Tower Hill Sales, F.W. Webb, Revision, Mitsubishi, Alliance Mechanical, Buckley Associates, ALBO Agency, Sterling Moving, Filter Sales and Service, Viega, Lightec, Anchor Insulation, Henry Scarano

Technical presentations:

Daryl Schoellkopf from F.W.Webb presented an overview of design issues with steam systems. The main takeaway was that most problems with steam systems, i.e. water hammer, were traceable to poor design of the piping systems. Daryl showed an video clip of how water hammer nearly cost a millwright, standing in a manhole above 125 psig steam pipes nearly lost his life when a steam line blew out below him due to water hammer.

Mark Ledgard-Compliance Programs Administrator with the NHDES Air Resources Division, explained the ins and outs of bringing free standing, wood fired boilers into compliance with EPA emission standards for particulates and VOCs. And Mark’s office handles complaints from neighbors due to excessive smoke from wood fired boilers. These boilers, unless grandfathered-in, may not be installed or even relocated on the original owner’s property if the boiler doesn’t meet current rules. A typical wood fired boiler that meets the prevailing EPA emission standards costs upwards of $10,000, not including installation.

Paul Giurlando of Fluid Equipment Solutions of New England presented a detailed explanation of how energy savings & equipment first cost reduction could be had by substituting multiple, smaller pumps, e.g. two or three pumps operating in parallel rather than the more typical 100% duty- 100% standby larger pump arrangement. Typical building HVAC load profile and operation were reviewed to demonstrate how advancements in technology (demand controlled ventilation, occupancy sensors, etc.) reduce anticipated peak loads and increase hours of operation under park load conditions. Since most pumps used for HVAC applications operate at part loads 90% of the year; pump selection stagey was discussed and reviewed to demonstrate how optimizing the pump efficiency for peak efficiency at part load conditions (when the pump will operate most hours of the year) results in energy savings for the life of the equipment.
