Abstract: The amount of the electrical energy used for the interior lighting of medium and large buildings is generally considerable. The European Standard EN15193 was devised to establish conventions and procedures for the estimation of energy requirements of lighting in buildings by an energy performance numeric indicator. This methodology is based on the three derating factors that consider the influence of the daylight exploitation, the occupancy behavior and, if present, of a constant illuminance sensor. The factors are evaluated by a statistical approach on the basis of general reference data tabulated by the same Standard, not considering more detailed parameters of the control system that can impact severely in the effective energy savings. The Standard methodology appears extremely useful for a preliminary evaluation. For a more accurate evaluation, this paper suggests an improvement of the procedure that considers the effective operation time and occupancy behavior, the type of control and lamps, the number of control groups, the technique of modulation (dimming or switching), and the delay in turning off. The suggested procedure is compared with the Standard one to highlight the improvements.
Duncan G. Stroik is a practicing architect, author, and Professor of Architecture at the University of Notre Dame specializing in religious and classical architecture. Gathered here are images from Christ Chapel, Hillsdale College Michigan. His award-winning work includes the Our Lady of the Most Holy Trinity Chapel in Santa Paula, California, the Shrine of Our Lady of Guadalupe in LaCrosse, Wisconsin, and the Cathedral of Saint Joseph in Sioux Falls, South Dakota.
A frequent lecturer on sacred architecture and the classical tradition, Stroik authored The Church Building as a Sacred Place: Beauty, Transcendence and the Eternaland is the founding editor of Sacred Architecture Journal. He is a graduate of the University of Virginia and the Yale University School of Architecture. Professor Stroik is the 2016 winner of the Arthur Ross Award for Architecture. In 2019, he was appointed to the U.S. Commission of Fine Arts.

What an incredible weekend for our swimming & diving teams! The women’s and men’s teams dominated at the UAA conference championships, with both bringing home their 25th consecutive conference titles!

§ 2701.1 Scope. The provisions of this chapter and NFPA 70 shall govern the design, construction, erection and installation of electrical components, appliances, equipment and systems used in buildings and structures covered by this code. The International Fire Code, the International Property Maintenance Code and NFPA 70 shall shover the use and maintenance of electrical components, appliances, equipment and systems. The International Existing Building Code and NFPA 70 shall govern the alteration, repair, relocation, replacement and addition of electrical components, appliances, or equipment and systems.
Many school districts, colleges and universities are affected by annual spring flooding in the Central United States; seasonal inspiration for revisiting the technical and management codes and standards to avoid and/or mitigate water damages that may be originate with host municipality water supply and control authorities.
The standards developed by the American Society of Civil Engineers (ASCE) and its affiliate institute — Environmental Water Resource Institute (EWRI) — should appear in the design guidelines given to professional services firms retained by the facility construction, operations and maintenance workgroups. We encourage our colleagues in these units to update their design guidelines with the latest versions of the documents linked below:
ASCE/EWRI 56: Guidelines for the Physical Security of Water Utilities. These water utility guidelines recommend physical and electronic security measures for physical protection systems to protect against identified adversaries, referred to as the design basis threats (DBTs), with specified motivation, tools, equipment, and weapons.
ASCE/EWRI 57: Guidelines for the Physical Security of Wastewater/Stormwater Utilities. These wastewater/stormwater utilities guidelines recommend physical and electronic security measures for physical protection systems to protect against identified adversaries, referred to as the design basis threats (DBTs), with specified motivation, tools, equipment, and weapons. Additional requirements and security equipment may be necessary to defend against threats with greater capabilities.
Note that these documents are “paired” for the obvious reason that potable water systems must be separate from all other water systems.
No redlines that are in the upper tier of our priority rankings are open for public comment at this time; though there are two that might interest building contractors:
Public Comment for ASCE-SEI 24 Flood Resistant Design and Construction (Comment Deadline 9/26/24)
Public Comment for ASCE/SEI 32-01 Design and Construction of Frost-Protected Shallow Foundations (Comment Deadline 8/05/2024
Public Comment on ASCE 7-22 Supplement for Chapter 5 (Comment Deadline 1-15-2023)
Public Comment on ASCE 7-22 Supplement for Referenced Standards (Comment Deadline 1-15-2023)
We encourage direct engagement by education industry leaders, their engineering consultants, or municipal water management experts to participate in the development of these standards through the ASCE standards portal:
You will need to set up an access account. You may also communicate directly with the American Society of Civil Engineers, 1801 Alexander Bell Dr., Reston, VA 20191. Contact: James Neckel (jneckel@asce.org).
We keep water-related ASCE titles on the standing agenda of our Water colloquium. See our CALENDAR for the next teleconference; open to everyone.
