Energy Efficiency: A way for colleges to save and make money?

The Obama administration – and every parent with a child in college – is concerned about the ever-escalating cost of higher education. And for good reason. Tuition, room and board rose 37 percent for undergraduates at public colleges and 25 percent at private colleges (adjusted for inflation) from 2000 to 2010, according to the …

Energy Audit and 5 Hot Tub Energy Saving Tips For Winter

Hot Tub's Ready to Go, Using Power All Winter

by Don Ames,   www.detectenergy.com

Finding a new address can be a little rough out here in the country. It doesn't help when the Google Map misses the important fact that a road is actually a dead end and it doesn't connect with another road like Google thinks. So I find two dead end roads instead of a nice continuous loop. And, as is always the case, I am on the wrong dead end. Oh well,…

Is There a Smart Home in Your Future?

iPhone to Home: It's All About Communication and Home Automation.

by Don Ames,  www.detectenergy.com

Right now, it's more of a joke than a reality. For some reason, even with an iPhone or Tablet in our hands, we fail to realize the fact that someday, in the near future, we will all be living in a Smart Home. Yes, for a while, it will probably be like coming to terms with our first…

Obama's budget good for energy efficiency

President Obama’s 2013 budget caused a lot of smiles this week among energy efficiency advocates – even if it is more of a wish list than anything else. Obama calls for about $1.2 billion in spending for energy efficiency.

 

What’s this mean to the energy efficiency industry?

Manual Thermal Control Is Always Best!



  

The finer points of thermostats are actually much more complicated than any published article covers. You must study each premium thermostat individually. If it does not have settings for swing, deadband, fan delays, early recovery, proper setbacks, etc., it's not really of good use. Dual fuel setups are even more complicated because you must decide whether to use the thermostat or the fossil fuel controller function for balance point control. You must also…

BCAP Gap Analyses a Resource for Midwest States

Energy Code Gap Analyses are reports that document a particular state’s energy code infrastructure to assess current gaps, identify best practices, and give recommendations for how these practices can be improved. The Building Codes Assistance Project (BCAP) has conducted several Gap Analyses over the course of the past year and these analyses can be a major step towards informing the state on how to reduce energy use by improving energy codes in those states. The gap analyses are part of…

Comfort as a Selling Point

One aspect of the HVAC industry that I believe many contractors are yet to embrace is that of utilizing comfort as a selling point. And by not doing so, they are missing out on potential business and falling farther behind the leaders of the industry. What I mean by this is that, over the past two decades, understanding of the indoor environment, indoor air quality and the interrelation of building systems has increased dramatically. Think AHRAE 55-2010, and the factors effecting human…

Opportunities for energy innovators

For a long time ‘clean’ and  ‘green’ marked the forward trend in the energy industry. Then came the quest for ‘smart’ energy.  And now ‘innovation’ is the buzzword.

 

It’s easy to see why.  As Americans, we believe our ability to innovate sets us apart in today’s international market.  Sure China can manufacture computers and cell phones more quickly and cheaply, but we came up with Google and IPhones in the first place.

 

The energy industry offers a lot of…
