AC equipment which exceed out-dated federal minimum efficiency levels. For additional information on equipment efficiency trade-offs refer to the ICF international study “Review and Analysis of Equipment Trade-offs in Residential Energy Codes”.
Example 2: On-site Renewable Energy Trade-offs
Another so-called “energy neutral” trade-off can occur when adding an on-site renewable energy system, such as roof top solar panels, to a building. Some propose to use renewable energy to trade-off building envelope insulation levels with similar performance impacts as discussed in Example 1.
Although the use of renewable energy is good and should be encouraged, it does not reduce the consumption of the building which is the role of energy conservation. The addition of renewables is not an excuse to weaken the thermal performance of the building envelope as it results in greater long term energy use. The appropriate application of renewable energy is as an additive measure after energy conservation (such as energy efficiency of the building envelope) has been achieved. This issue is addressed in more detail in two separate articles: "What Are the Pillars of a Sustainable Building Future?" and "Energy Efficiency or Trade-offs - Focus on What First?".
Implications
There are multiple ramifications of trading-off building envelope performance as demonstrated in the above two examples that necessitate having a backstop to prevent the building envelope from becoming a “foul ball”:
Permanence and Durability: The building envelope provides the most durable and lasting form of energy efficiency. It works 24-7 for 365 days a year over the life of a building. It is the most permanent and reliable energy efficiency practice and requires essentially no maintenance or replacement. When done well, it also protects the durability of the structure and its contents. Unlike building envelope measures like insulation, HVAC equipment and renewable energy systems do not have a service life that is consistent with the life of the building.
Cost-Effectiveness: The most cost-effective time to maximize efficiency of the building envelope is when it is newly constructed. It is very expensive to make significant improvements to the envelope after initial construction. It is imperative that building envelopes not be weakened at the time of construction.
Affordability: There is no free lunch! This is a matter of pay now or pay later. The new energy efficient buildings of today are the energy efficient affordable to own and operate existing buildings of tomorrow. Good building envelopes almost always allow you to decrease the needed size of your HVAC or renewable energy system making them more affordable as well.
Comfort: Well insulated and air-sealed envelopes with mitigated thermal bridges provide a more comfortable and easier to control indoor environment. Occupants tend to offset uncomfortable conditions by increasing or lowering set point temperature, resulting in more energy use and also potentially increased risk of moisture problems.

This is the first course of the Groundrod series, which establishes the educational foundation of secure internet and device usage in the age of Pri$m.
The Groundrod Primer course is designed to incorporate a high level of student interaction. You will learn by doing.
If you’ve been reading TOWR for any length of time then you understand why this class is needed, and why you need to be there. The bottom line is this: If you do not have the skills in this class, then you are putting the people you work with in danger. We are long past the point where lack of skills is acceptable.
This is NOT like our other classes. Participants will be vetted and approved to attend. Once you are vetted and approved, you will be registered in the class. Cost is $220 per person, but if there is a hardship, please contact us. Do not allow the cost to deter you from taking this course.
Class location will be given to each participant but not posted publicly.
This class will be taught by K@CSG. His bio can be found here.

NBA Games Have All Been Suspended!
Listen up, NBA fans!
The season has just been put on hiatus because an Utah Jazz player just tested positive for the coronavirus!
There was a little bit of drama at Oklahoma City, just before the game between Jazz and Thunder began. After about a 20-minute delay, the crowd was told that the game has been postponed due to ‘unforeseen circumstances'.
The league tweeted that the suspension would take effect after the completion of Wednesday’s schedule.
BREAKING: The NBA has suspended the season and will use the "hiatus" to determine next steps moving forward.
During this hiatus, the team will determine the next steps for moving forward in the regard to the pandemic.
So for now, we guess it’s best to stay indoors, or to reduce going out for social gatherings at least. Please stay safe, everyone!
