The National Association of Architectural Metal Manufacturers (NAAMM) provides consensus products for specifications, procedures, and terminology for metal bar grating, expanded metal, hollow metal doors and frames, metal flagpoles, metal stairs and railings, and metal lathing and furring.   As an ANSI accredited standards developer it provides public commenting opportunities on its consensus products; linked below:

We encourage our colleagues to communicate directly with the standards staff at NAAAM: Vernon (Wes) Lewis, 123 College Place #1101, Norfolk, VA 23510, (757) 489-0787, wlewis7@cox.net.  At the moment we find no public commenting opportunities but on selected holidays we revisit its flagpole standard.  Keep in mind that this document has a scope that is limited to the product and its appropriate application and maintenance only:

Non-Contact Heart Rate Monitoring in Neonatal Intensive Care Unit using RGB Camera

Non-Contact Heart Rate Monitoring in Neonatal Intensive Care Unit using RGB Camera

Quiong Chen, et. al

Center for Intelligent Medical Electronics, School of Information Science and Technology, Fudan University, Shanghai, China

Abstract:  Heart rate (HR) measurement is crucial for newborn infant monitoring in the neonatal intensive care unit (NICU). The widely used contact HR measurement methods based on electrocardiography (ECG) and photoplethysmography (PPG) signals can lead to discomfort and possible skin irritation on neonates, which limit its application in NICU scenarios. In this work, we propose a non-contact HR monitoring method simply using a RGB camera. Eulerian video magnification (EVM) is employed to detect the subtle changes of neonatal faces results from blood circulation. The magnified signal is then transformed to the spectral domain to extract HR information. Compared with the widely investigated independent component analysis (ICA)-based HR measurement method using video recordings, the proposed method can achieve the real time HR measurement, which is a significant superiority in NICU neonatal monitoring. To the best of our knowledge, this is the first study to employ EVM algorithm in real time neonatal HR monitoring.

Church heating: Comparison of different strategies

N. Aste. et al

Department of Architecture, Built Environment and Construction Engineering, Politecnico di Milano

 

Abstract:  Church heating represents a challenging task because multiple goals have to be fulfilled simultaneously, such as the thermal comfort for the occupants and the optimal internal environmental conditions for the preservation of building components and artworks. In addition, current requirements for environmental and economic sustainability impose to make efforts to minimize the amount of energy needed and the consequent environmental/economic impact. In this context, the present work represents the assessment of the energy, environmental and economic impact of different strategies for church heating, including a novel technology based on the exploitation of renewable energies. The analysis was carried out in a real case-study building, represented by the Basilica di S. Maria di Collemaggio (L’Aquila, Italy), a church of worldwide relevance, currently under restoration.

“I think we ought to read only the kind of books that wound or stab us. If the book we’re reading doesn’t wake us up with a blow to the head, what are we reading for? So that it will make us happy, as you write? Good Lord, we would be happy precisely if we had no books, and the kind of books that make us happy are the kind we could write ourselves if we had to. But we need books that affect us like a disaster, that grieve us deeply, like the death of someone we loved more than ourselves, like being banished into forests far from everyone, like a suicide. A book must be the axe for the frozen sea within us. That is my belief.”

Critical Operations Power Systems: Improving Risk Assessment in Emergency Facilities with Reliability Engineering

University of Michigan | Ann Arbor, Michigan
HP Critical Facilities Services | Bethesda, Maryland
Mark Beirne

DLB Associates | Chicago, Illinois

Abstract. The key feature of this article is the application of quantitative method for evaluating risk and conveying the results into a power system design that is scaled according to hazards present in any given emergency management district. These methods employ classical lumped parameter modeling of power chain architectures and can be applied to any type of critical facility, whether it is a stand-alone structure, or a portion of stand-alone structure, such as a police station or government center. This article will provide a risk assessment roadmap for one of the most common critical facilities that should be designated as COPS per NEC 708-a 911 call center. The existing methods of reliability engineering will be used in the risk assessment.

Best is water

— Pindar 476 B.C.

 

The American Water Works Association (AWWA) has an extensive catalog that sets the standard of care for water quality and piping systems running through all communities.

Download: Full List of AWWA/ANSI Standards

We approach them from the point of view of education communities; some with agriculture, vast hospital systems heavily dependent upon a higher level of water quality and district energy plants.  Like most every technology in the United States, water issues enliven political discourse.   Essential features of water supply — such as backflow protection, separation, piping systems to playground water fountains, etc. — are subordinated to fury over to access and tariff issues.   For the moment we steer away from them.

The landing page for the AWWA standardization enterprise is linked below:

Standard Notices

The original University of Michigan standards advocacy enterprise engaged in some back-and-forth with the backflow and cross-connection technical committees.   It found ambiguity in the language found in AWWA C510-C511-C512 covering reduced pressure zone (RPZ) values that caused some education facility units to over-specify RPZ valves for all facility classes.   Many research universities have enterprises that create toxic water waste which must be blocked from entering the municipal water supply.  Some of that back-and-forth is recounted in the workspace linked below.

We found that minimum requirements for backflow prevention technology was easier managed at state level plumbing safety administrative boards.

Several AWWA standards are now open for public review; AWWA G430 Security Practices for Operation and Management among them.  We point you toward them; though, in the interest of resource conservation, we will follow but not advocate user-interest in this product at the moment.  It appears to have stabilized compared with other standards in the water safety domain (though that could change).

Comments due August 9th.  

Ingham

We find AWWA best practice literature heavily referenced in school district, college and university design guidelines and construction contracts.   We do a status check of the AWWA suite every month during our Water teleconferences.  See our CALENDAR for the next online meeting; open to everyone.

Legionellosis Risk Management

The human mind evolved to believe in the gods.

It did not evolve to believe in biology.

— E.O. Wilson

 

 

The American Society of Heating and Refrigeration Engineers  publishes two Legionella-related standards:

ASHRAE 188: Legionellosis: Risk Management for Building Water Systems

ASHRAE 12:  Managing (Minimizing) the Risk of Legionellosis Associated With Building Water Systems  (Maintained continuously)

Legionella risk is a domain rich in possibilities for lawsuits so we should not be surprised that best practice titles in the ASHRAE suite — and other standards bibliographies — go unstable with new findings.  We encourage facility units in education communities to contribute data to technical committees and to participate directly.  you may access titles open for public comment at the link below:

ASHRAE Public Review Draft Standards

ASHRAE runs one of the best public consultation facilities in the United States.  Its titles appear in most of our daily colloquia; this one best practice titles are on the standing agendas of our Energy, Mechanical, Water 200/Water 400 and Risk colloquia.  See our CALENDAR for the next online meeting; open to everyone.
