Granite State Chapter of ASHRAE
Meeting Notice
November 8th, 2018

Have you ever been frustrated after driving the length of the State on a snowy weekend for a service call, only to hear that the problem the occupants complained about so bitterly is no longer occurring? Or have you ever been curious about whether anything you ever designed or installed actually works and is being maintained? Or perhaps you’re just one of those skeptical people who don’t trust energy models, and therefore lust after more real-world data than normal people care about, so you can really understand the behavior of buildings and HVAC systems?

If so, you’re in luck. Real-time, cloud-based remote monitoring is finally affordable for those of us who are simply curious, rather than just for organizations that have piles of cash and staffers with lots of extra time. This workshop will focus on lessons learned about buildings and HVAC systems after using an economical cloud-based system. It will also include live, ad-hoc interaction with attendees, using that system in real-time for remote diagnostics, and for exploring and understanding the behavior of several buildings over time.

I hope you will plan to join us for this interesting and informative discussion.

Presentation Summary

peaker Biography

Mr. Sharp is the chairman of Aircuity, Inc. and has over 25 years of wide-ranging entrepreneurial experience and more than 25 U.S. patents in the fields of energy efficiency and laboratory controls. As founder, former president and CEO of Phoenix Controls, he led the development of this world leader in laboratory airflow controls that was acquired by Honeywell in 1998. The technologies invented by Mr. Sharp at Phoenix Controls are today saving over $1.5 billion annually in energy use. In 2000, Mr. Sharp founded Aircuity, which was spun out of Honeywell and is a smart airside energy efficiency company.

Mr. Sharp is a graduate of MIT with bachelors and masters degrees in electrical engineering. He is Executive Vice President and a member of the board of directors of I2SL (International Institute for Sustainable Laboratories), the nonprofit foundation that operates the Labs21 conference. He is also a member of two important standards on ventilation: the ANSI/AIHA Standard Z9.5 Committee on Laboratory Ventilation and the ASHRAE SSPC 170 Committee on Ventilation of Health Care Facilities. He is also a voting member of ASHRAE technical committee TC9.10: Laboratory Systems and TC9.11: Clean Spaces/Cleanrooms.


Bring a Member Program

In the interest of increasing the Granite State ASHRAE membership, we are instituting a "Bring a New Member Program". Any ASHRAE member can bring a potential new member at no charge, and if they end up joining then you will receive free admission to a future meeting.


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.
