Electropedia: The World’s Online Electrotechnical Vocabulary

Public Consultations

Public consultation on joint ISO standard 80000 that defines quantities and units for space, time, thermodynamics, light, radiation and even the characteristic numbers for each of the foregoing closes October 11th.

“City at night” 1958 | Harald Rudyard Engman

Electropedia is produced by the world’s peak electrotechnical standardization organization that oversees 214 technical committees that provide a neutral and independent platform where agreement can be found on electrotechnical solutions with global relevance and reach.  The IEC operates close-coupled with the European Committee for Electrotechnical Standardization (CENELEC)

The highest level of standardization for the building interiors on the emergent #SmartCampus originates in ISO TC 205 — Building Environment Design.  This committee is charged with standards setting in the design of new buildings and retrofit of existing buildings for acceptable indoor environment and practicable energy conservation and efficiency. Building environment design addresses the technical building systems and related architectural aspects, and includes the related design processes, design methods, design outcomes, and design-phase building commissioning. Indoor environment includes air quality, and thermal, acoustic, and visual factors.  The business plan is linked below:

STRATEGIC BUSINESS PLAN ISO/TC 205

Some of the key ideas in the scope of this project are listed below:

– the design of energy-efficient buildings
– building control systems design
– indoor air quality
– indoor thermal environment
– indoor acoustical environment
– indoor visual environment
– radiant heating and cooling systems
– heating and cooling systems
– building commissioning planning
– moisture in buildings

We see many of the foregoing ideas in the catalog of ASHRAE International — ANSI’s US Technical Advisory Group Administrator in this project, as well as a number of others (CLICK HERE).   There are 31 Participating member and 28 Observing member nations.

Generally speaking, ISO consensus products are performance standards and contrast sharply with prescriptive standards in the energy-related domains in the United States.  Prescriptive standards are easy to enforce but difficult to write.  Performance standards are easy to write but difficult to enforce.

Facility managers that oversee building automation units in education communities in the United States are encouraged to participate in the development of ISO 205 by communicating directly with Brian Cox at ASHRAE (bcox@ashrae.org).  We keep all ISO standards on the standing agenda of our periodic Global and AEdificare standards colloquia.  We also maintain this committee’s catalog on the standing agenda of our Mechanical colloquium.  See our CALENDAR for the next online meetings; open to everyone.

Smart Infrastructure is a global opportunity worth £2trn-4.8trn. The world is experiencing a fourth industrial revolution due to the rapid development of technologies and digital abundance.

Smart Infrastructure involves applying this to economic infrastructure for the benefit of all stakeholders. It will allow owners and operators to get more out of what they already have, increasing capacity, efficiency and resilience and improving services.

It brings better performance at lower cost. Gaining more from existing assets is the key to enhancing service provision despite constrained finance and growing resource scarcity. It will often be more cost-effective to add to the overall value of mature infrastructure via digital enhancements than by physical enhancements – physical enhancements add `more of the same’, whereas digital enhancements can transform the existing as well.

Smart Infrastructure will shape a better future. Greater understanding of the performance of our infrastructure will allow new infrastructure to be designed and delivered more efficiently and to provide better whole-life value.

Data is the key – the ownership of it and the ability to understand and act on it. Industry, organisations and professionals need to be ready to adjust in order to take advantage of the emerging opportunities. Early adopters stand to gain the most benefit. Everyone in the infrastructure sector has a choice as to how fast they respond to the changes that Smart Infrastructure will bring. But everyone will be affected.

Change is inevitable. Progress is optional. Now is the time for the infrastructure industry to choose to be Smart.

Perspective: Since this paper is general in its recommendations, we provide examples of specific campus infrastructure data points that are difficult, if not impossible, to identify and “make smart” — either willfully, for lack of funding, for lack of consensus, for lack of understanding or leadership:

    1. Maintenance of the digital location of fire dampers in legacy buildings or even new buildings mapped with BIM.  Doors and ceiling plenums are continually being modified and the As-Built information is usually not accurate.  This leads to fire hazard and complicates air flow and assuring occupant temperature preferences (i.e. uncontrollable hot and cold spots) 
    2. Ampere readings of feeder breakers downstream from the electric service main.  The power chain between the service substation and the end-use equipment is a “no-man’s land” in research facilities that everyone wants to meter but few ever recover the cost of the additional metering.
    3. Optimal air flow rates in hospitals and commercial kitchens that satisfies both environmental air hazards and compartmentalized air pressure zones for fire safety.
    4. Identification of students, staff and faculty directly affiliated with the campus versus visitors to the campus.
    5. Standpipe pressure variations in municipal water systems
    6. Pinch points in municipal sewer systems in order to avoid building flooding.
    7. How much of university data center cost should be a shared (gateway) cost, and how much should be charged to individual academic and business units?
    8. Should “net-zero” energy buildings be charged for power generated at the university central heating and electric generation plant?
    9. How much staff parking should be allocated to academic faculty versus staff that supports the healthcare delivery enterprises; which in many cases provides more revenue to the university than the academic units?
    10. Finally, a classical conundrum in facility management spreadsheets: Can we distinguish between maintenance cost (which should be covered under an O&M budget) and capital improvement cost (which can be financed by investors)

When the wicked problems of peace and economic inequality cannot be solved, political leaders, and the battalions of servile administrative muckety-mucks who report to them, resort to fear-mongering about an imagined problem to be solved centuries hence assuming every other nation agrees on remedies of its anthropogenic origin.  We would not draw attention to it were it not that large tranches of the global academic community are in on the grift costing hundreds of billions in square-footage for research and teaching hopelessness to our children and hatred of climate change deniers.

Recognizing signs and doors for Indoor Wayfinding for Blind and Visually Impaired Persons

Mouna Afif, et al

 

Abstract:  Indoor signage plays an essential component to find destination for blind and visually impaired people. In this paper, we propose an indoor signage and doors detection system in order to help blind and partially sighted persons accessing unfamiliar indoor environments. Our indoor signage and doors recognizer is builded based on deep learning algorithms. We developed an indoor signage detection system especially used for detecting four types of signage: exit, wc, disabled exit and confidence zone. Experiment results demonstrates the effectiveness and the high precision of the proposed recognition system. We obtained 99.8% as a recognition rate.
