ASHRAE Technology Awards 2015

ASHRAE Technology Awards – Wisconsin Projects

Each year ASHRAE awards its members that develop innovative building designs applied to occupant comfort, indoor air quality and energy conservation.  The designs incorporate ASHRAE standards for energy management and indoor air quality.  We are currently looking for candidates from the Wisconsin Chapter that incorporate those unique and innovative design ideas into their projects.  Categories include residential, public assembly (new, existing, Retrocommissioning), commercial buildings (new, existing, Retrocommissioning),  institutional buildings (new, existing, Retrocommissioning, includes educational facilities and other institutional), health care facilities (new, existing, Retrocommissioning) and industrial facilities or processes (new and existing).

Please use the following link for more information on the awards program: www.ashrae.org/cttc.  Winners for each category will be determined by the Wisconsin Chapter Board of Governors.  The winner in each category will be eligible to be submitted to the regional and national level to showcase projects designed by Wisconsin Chapter members.  Performance must be proven through one year of verified operating data.  Please submit your award applications to the Wisconsin Chapter CTTC Chair, Ryan McNally (ryan_w53716@yahoo.com), by March 25th, 2015.

RTU OPTIMIZATION

Packaged rooftop units (RTUs) are used to easily and effectively heat and cool more than 50% of all commercial buildings, but are they efficient?  The cooling efficiency improvements in the refrigeration circuits have improved slightly in the past 10 years and the average gas efficiency has improved from 80% to just 82%.  What else can we do to make a simple RTU use significantly less energy to heat and cool our structures?  A recent 2013 Department of Energy study explored this exact question and the solution is summarized by the term Advanced Rooftop Control or ARC.  This seminar will explore that ARC research and several options for existing (or new) RTUs to save 24 to 35% of the fan, cooling, and heating energy.

 Review of What We Already Know… but maybe don’t implement enough

  • Programmable Thermostats: recommended settings, OA interlocks, and Wi-Fi… duh, everything with an App is better
  • Economizers: dry-bulb vs. enthalpy, integrated economizing, and recommended settings… yes you have been too conservative
  • Demand Controlled Ventilation (DCV): basic concept, sensor reliability, recommended settings, and “is that allowed in Wisconsin?”
  • Code requirements, utility rebates, and energy savings calcs for all of the above

What is New?… or at least new again

  • Multi-speed fan control of “Constant Volume” systems
  • Name Game: Staged Air Volume (SAV), Single Zone VAV, Multi-stage Air Volume (MSAV)
  • How is SAV different than VAV?
  • What good is a VFD on a “constant volume” RTU?
  • How is it controlled?
  • Is it required by energy codes or standards?
  • Energy savings and utility rebates

What about ERVs, Variable Capacity Compressors, Dynamic Balancing Systems, and Magic Black Boxes… oh, we love those magic elixirs

  • It is not easy jamming 4 hours of topics into an hour, so we cannot cover everything
  • Never fear, we can direct folks to recorded webinars if they want to learn more about some of these technologies
  • And of course there is always cocktail time… Ryan would be happy to discuss any of these topics with you

ASCE AEI Conference 2015

The Architectural Engineering Institute (AEI), in partnership with the Milwaukee School of Engineering (MSOE), is pleased to announce the 6th Biennial Professional Conference for 2015. The theme of the conference is the “Birth and Life of the Integrated Building.”

The conference offers an opportunity for members of the building construction industry, including structural, mechanical, and electrical engineers, construction management professional and architects, to learn about and discuss advanced strategies and state-of-the-art practices of building technology. The conference offers a balance between academics and practice and will offer presentations, panel discussions, workshops, technical paper sessions, keynote presentations, local tours of technical interest, a student competition and professional practice awards. In addition, MSOE will be hosting a career fair the night before the conference that is open to all Civil and Architectural Engineering and Construction Management employers and students.
