Why the President's Climate Change Proposals Don't Matter!

1. Not many will listen to him, as 50% of the US population are right-wing  registered republicans(me too sorta, but a moderate!)

2. China can't be persuaded in any way shape or form to change their prodigious rate of economic growth & CO2 production. btw, we owe, we owe them! we are a debtor nation, to the enemy!

3. If you control coal-fired plants here, the coal interests will simply sell more U.S. coal to export!

4. We're past the global…

Changing The Way We Use AC

Aside from vacations, longer days and spending time in the great outdoors summer brings with it oppressive heat resulting in large segments of the population blasting the AC.

This often translates into long hours of high energy usage which, depending on how much its relied upon, has a tendency to become routine throughout the warmer months.



Since AC spikes power usage more than most other…

The Process Approach of Human-Building Interaction (HBI)

Reposted from i.e., the Center for Energy and Environment's Innovation Exchange blog -- http://mncee.org/Innovation-Exchange/ie/

In the early nineties, I began developing interactive CD-ROMs to teach school age children about energy and environmental issues. We created games to teach these concepts. An essential step in our process was…

Window Improvement vs. Window Replacement

Most energy audit reports place windows very low on their list of energy improvement priorities. This isn't surprising because of the relatively high cost of replacement windows coupled with what are commonly marginal improvements in their thermal performance. Since audit reports generally prioritize energy efficiency improvement opportunities according to their cost vs. thermal benefit  (fuel savings) ratio, the energy…

Zero to 60 - Scores of Green Appraisers Hit the Streets Overnight in Colorado

Home builder Sean Smith feels like Sisyphus – the Greek mythological figure doomed for eternity to push boulders uphill only for them to crash downhill when he neared the top.  Smith’s boulder?  Higher appraisal prices for the green homes he builds in metro Denver.

Code Conflict Between 2012 IRC and 2012 IECC

It has come to my attention that there may be a building science-based conflict in the language of the 2012 International Residential Code (IRC) and 2012 International Energy Conservation Code (IECC).

The 2012 IECC sets the mandatory blower door tested and certified air infiltration rate at 5 ACH50 in CZ1 & 2 and an even tighter 3 ACH50 in CZ 3 and above. The problem lies in the fact that the new…

Home Performance and HVAC Contractors: Recent Legislative Initiative In Texas

As energy auditors and raters went about their business of testing homes, performing energy audits and HVAC system inspections, they discovered and reported certain “problems” to the homeowners of Texas. For example, they reported that HVAC systems were oversized, or suffering from massive duct leakage! In late 2011, The Texas Department of Licensing and Regulation (TDLR), which oversees the HVAC industry,…

Three WWWs to completing the Appraisal Institute’s Residential Green and Energy Efficient Addendum

The Residential Green and Energy Efficient Addendum is a form used to standardize the reporting of high performance house features from green certifications to incentives offered.  The Addendum can be downloaded in a PDF format from the Appraisal Institute’s Website.  It is seems there is much confusion on who should be completing the Addendum, why they should complete it and what they…

Excellent PBS Energy Program Worth Watching

In case you missed it, PBS has been airing a series "EARTH: The Operators Manual".  The  recent episode which aired last week "Energy Quest USA" is well worth watching...

While many of us discuss methods and marketing for audits and retrofits, I believe it is the community neighbor-to-neighbor programs and activities that engage the homeowner and get results. The show profiles communities making smart energy choices based on economics and the environment. Below is a link to the…

Efficiency

Prior to any real consideration of adopting alternative energy sources like wind or solar, it is paramount to consider a homes energy inefficiencies.  Cost savings are negated, almost immediately, when you attempt to power a home through revolutionary methods and antiquated building materials / practices.

The two subject matters have to be in congruence for the conversation of 'renewable', 'green' (whatever that really means) and 'sustainable' to carry any relative meaning.

Why Getting a Quantum Heat Pump is a Better Choice?

Hot water is a basic necessity in every home and office during winters. So it is very important to have some efficient source to heat water. Rather than using those traditional methods such as fire to get warm water, you can avail the benefits of advanced heating technology using a quantum heat pump.



Using such an energy-efficient heat pump can ease up your life to a significant extent. With its…

Momentum builds for energy efficiency...but is the wolf at the door?

It says something that Ernest Moniz chose to deliver his first public talk as US energy secretary to an energy efficiency crowd.

His appearance last week at EE Global in Washington, D.C. was a surprise of sorts. And the timing was significant. Moniz had only been confirmed as energy secretary three hours before taking the podium at the Alliance to Save Energy’s annual conference.

Why did he make the stop?

Probably not because of the size of the crowd. About 550 people…

Change is Hard—How Do You Get People to Accept It?

Changing one’s daily routine and making big decisions about money is hard. When a home performance contractor asks a customer to consider an audit, they are asking a lot. Besides the cost of the audit and any retrofit measures the homeowner chooses to pay for, which is probably the biggest challenge, there is also the inconvenience. The audit and retrofit may require the homeowner to take time off from work. Having workers climb in and out of the attic, under the crawlspace, and drill holes…

HOMES Act introduced with Bi-Partisan Sponsorship

We don't see a lot of bi-partisan bills in Congress these days. Here's one focusing on home energy-efficiency from a WV-R and a VT-D, both on the energy committee, the HOMES Act, HR 2128 (http://hdl.loc.gov/loc.uscongress/legislation.113hr2128) introduced yesterday.  Now, I'm not holding my breathe on passage, but I take it as a good sign that energy-efficiency is part of the…
