Paying for downgrades

 

We’re celebrating February with 29 bits of wit, wisdom and witticisms – one for each day of the month. Most are original, some are borrowed, a few are derivatives from other fields - all should be considered seriously. Share with those that care...

  1. If some cause and effect relationships are not fully established scientifically - it’s best to take precautionary measures.

  2. If building to ASHRAE Standards is considered an upgrade, then building anything below an ASHRAE Standard must be considered a downgrade...so are you paying too much for downgrades? Think about it.

  3. Creating 2800°F flame temperatures in a 98% efficient furnace or boiler to maintain 72°F is not sustainable no matter how you look at it.

  4. Proponents of naturally ventilated spaces might want to consider the stack effect and powerful draft it pulls when the outside air is hot, humid and polluted. At over 10 air changes per hour it only takes minutes for the quality of the indoor air to become the quality of the outdoor air.

  5. We don’t inhale thermal comfort - it's sensed predominately through our skin with radiation being one of the defining factors - so remind me why we try to use air exclusively to condition people?

  6. 100% of all condensation problems in buildings conditioned exclusively with air did not have radiant cooling panels to blame. Go figure.

  7. Once again for the gazillionth time…indoor air quality is not a proxy for thermal comfort quality.

  8. We're repositioning HVAC under the healthcare, cash flow mgmt. & asset protection industry instead of construction, are you ok with that?

  9. Don’t ya just wish the makers of Clearasil would come up with paint to vanish away all the control acne adoring the walls of American homes?

  10. Are we done polishing the cannon balls in architecture, building construction and engineering? I mean, if you can’t measure beyond two decimals places it hardly makes sense to calculate to four!

  11. If architects and their clients really cared about energy and IEQ they’d stop commissioning origami buildings.

  12. Developers of CADD programs have figured out how to make everything plumb, level and square so that contractors have something to laugh at over safety meetings and coffee breaks.

  13. How do you figure that an electric based HVAC system is 100% efficient when it’s connected to a coal fired power plant where the cooling tower spews copious amounts of unused energy into the environment? A cooling tower at a power plant is by far the biggest oxymoron known to mankind.

  14. Building scientists, interior designers, HVAC and lighting engineers are to the building as DNA is to the body. This is why architects should only be commissioned after the DNA has been defined.

  15. Architecture constructs a judgment conflict between what you spend on sight stimulations versus what you spend on what you smell + feel + hear.

  16. A very famous architect recently stated something that could be interpreted as,  “sustainability is thoughtless and a mantra for less talented people to get their way.” You’ll have to guess who it is but his first name was Frank and his last name rhymes with scary.

  17. 125 million visual receptors per eye vs. appx 166,000 thermal sensors in the skin - is why, “In a Town Called Comfort, Only the Blind Can See”.

  18. If construction were a ProAm boxing match, where would the minimum requirements of the building codes be positioned?

  19. If ASHRAE's High Performance Buildings is not the cook book for your new building you may want to look for another chef.

  20. Let’s make complicated programmable thermostats’ with small little buttons and a 20 page manual printed in #6 font and then sell them to older people who have or are losing their visual acuity, manual dexterity and cognitive ability. Duh?

  21. Is it true - if all one knows about is air filtration, everything looks like particulate?

  22. 100% of all hardwood flooring problems in buildings conditioned exclusively with air did not have radiant floor heating to blame.

  23. EcoBling for houses, a sure cure for EcoGuilt - the gift that keeps on giving! Available now without prescription at your local RES outlet.

  24. Sales before science is just wrong! A message to those selling high efficiency appliances for systems needing to operate above the combustion gas dew point.

  25. The hereditary conflict between consumer and contractor is borne unto every construction project from the process of building for bullion versus building for the body.

  26. We can move forward once the construction industry grasps the H in HVAC is not exclusively heating comfort, the V is not exclusively air quality and the AC is not exclusively cooling comfort.

  27. They are part of the autonomic functions of the body, the ASHRAE Standards attempt to reflect them and the commerce of contracting gets to ignore them. Guess what “they” are?

  28. Help me understand why most HVAC technicians say separate ventilation systems are more effective but the problem with hydronics is you need one? Duh?

  29. If the thermostat is supposed to be our thermal ambassador to the HVAC system, why doesn’t it sense what we sense? Does this make sense?

There you have it...our ode to each day in February, 2012 - have a great year.
