Java Zen:Thinking Out Loud Thursday, 2018.03.22
Weapons are the tools of violence;
 all decent men detest them.
 Weapons are the tools of fear;
 a decent man will avoid them
 except in the direst necessity
 and, if compelled, will use them
 only with the utmost restraint.

 Peace is his highest value.
 If the peace has been shattered,
 how can he be content?

 His enemies are not demons,
 but human beings like himself.
 He doesn't wish them personal harm.
 Nor does he rejoice in victory.
 How could he rejoice in victory
 and delight in the slaughter of men?

 He enters a battle gravely,
 with sorrow and with great compassion,
 as if he were attending a funeral.

		Lao Tzu, Tao Te Ching


Cool On Top

As in Cool Roofs:

Over 90% of the roofs in the United States are dark-colored. These low-reflectance surfaces reach temperatures of 150 to 190°F (66 to 88°C) and contribute to:

  • Increased cooling energy use and higher utility bills;
  • Higher peak electricity demand, raised electricity production costs, and a potentially overburdened power grid;
  • Reduced indoor comfort;
  • Increased air pollution due to the intensification of the “heat island effect”; and
  • Accelerated deterioration of roofing materials, increased roof maintenance costs, and high levels of roofing waste sent to landfills.

In contrast, cool roof systems with high reflectance and emittance stay up to 70°F (39°C) cooler than traditional materials during peak summer weather. Benefits of cool roofs include reduced building heat-gain and saving on summertime air conditioning expenditures. By minimizing energy use, cool roofs do more than save money – they reduce the demand for electric power and resulting air pollution and greenhouse gas emissions.

Unfortunately, there are tens of thousands of Home Owner Association fiefdoms in the way of making something like this happen. There really are many, many simple solutions to the problem, but how do you whip up a fearful frenzy about white roofs? It’s much more satisfying to smack down a Hummer driver or gloat over that shiny new Prius in the driveway.
