How can you help NGBS Green?

EnergyLogic is a National Green Building Standard (NGBS) Green advocate. We believe it is affordable and among the most rigorous green building rating systems available, and we believe that developers should have a choice of green certification programs.

The City of Denver is currently collecting comments on their Green Roofs Building Policy Proposal. In short, they have proposed that as an alternative to the mandate for a green roof, new and existing buildings are allowed to install a cool roof and elect for LEED Gold or Enterprise Green Communities certification.

The Denver Department of Public Health and Environment (DDPHE) is leading a formal stakeholder engagement and public input process to review and possibly modify Denver’s Green Roof Ordinance. Based on the ICC/ASHRAE – 700 National Green Building Standard (NGBS), EnergyLogic has respectfully requested that NGBS Green Certification be recognized as a named alternative to LEED Gold or Enterprise Green Communities as one of the allowable green certification compliance options for new or existing building to comply with the Denver Green Roof requirements.

Will you join us in supporting NGBS?

Please consider sending comments requesting that NGBS Green is included as a certification option for their policy.

Comments are due by noon on June 3rd and can be sent to Katrina Managan via email:

Get Ready for an Exciting Summer with Berthoud Habitat for Humanity!

This is a unique opportunity for you to partner with Berthoud Habitat for Humanity in supporting a special home built by students at the New York City College of Technology (NYCCT).

Every 2 years the U.S. Department of Energy puts on a “Solar Decathlon” to challenge collegiate teams to design, build, and operate solar-powered houses that are cost-effective, energy-efficient, and eye-catching. Teams work on creating the best blends of affordability, consumer appeal, and design excellence with optimal energy production and maximum efficiency.

For the 2015 Solar Decathlon, NYCCT put together a team of 60+ students to design and construct a resilient, energy-efficient home that could adapt to the needs of a diverse urban community. Thus, TeamDURA was created:  Diverse, Urban, Resilient, and Adaptable.

Check out the videos below to learn about the team’s 2015 Solar Decathlon journey:

EnergyLogic Inspection Report Updates

If you thought that communicating the status of an inspection would be straightforward you would be wrong.    Therefore, in an effort to better ensure clarity and consistency in the delivery of our inspection reports we will highlight the following changes, effective Monday, May 21, 2018. 

One very important change is regarding inspection report language.

The term “Builder Sign Off” will be changed to “Fix and Proceed”.  Items that were formally designated as a “Builder Sign Off” will now be designated with hammer icon and a “Fix and Proceed” message.

   Fix and Proceed

   Correct and Re-inspect

   Photo Re-Inspection 

  • These are inspection items that fail to meet the intent of a program or code but are minor in nature and do not warrant an on-site re-inspection.  They, however, must be fixed in order to ensure compliance with the appropriate code or program.  Any issue designated as “Fix and Proceed” becomes the sole responsibility of the Builder’s field construction management team.
  • Items that were formally designated as a “Failure” will be replaced with the message “Correct and Re-inspect”.  The “Correct and Re-inspect” designation is for inspection items that clearly fail to meet the intent of a program or code and are serious enough in nature to require on-site verification that the item has been corrected.
  • EnergyLogic has added a “Photo Re-inspection” ability which will be designated using a blue camera icon on our reports.   “Photo Re-inspection” is an option used at the discretion of the HERS Rater. It can be used when, and only when, all “Correct and Re-inspect” items do not warrant an on-site re-inspection.

For example, if five items are called out as “Correct and Re-inspect” and four of them could be “Photo Re-inspected” but one needs an on-site inspection the entire group would be assigned “Correct and Re-inspect” with an on-site re-inspection as a trip is required.  On the other hand, if at the time of re-inspection some inspection items have not been fully fixed but it is clear that they are being addressed, a “Correct and Re-inspect” may change to a “Photo Re-inspection”.

Regardless, when “Photo Re-inspection” is called out items need to be addressed, photo documented and sent to the Rater as quickly as possible or an on-site re-inspection may be ordered, drywall may need to be removed, and all kinds of issues could arise. It is EnergyLogic’s expectation that photos will be received within 24-36 hours to verify that the item has been corrected.

It is obvious that every scenario can’t be exemplified here so I want to make it clear that inspection items will be assessed and allocated as Passed, “Fix and Proceed”, “Correct and Re-inspect”, or “Photo Re-inspection” at the sole discretion of the Rater based on their judgment. EnergyLogic is always open to dialogue so please ask questions of our field rating team whenever needed and we will do our best to get you the clarification you need in the timeliest manner possible.

Lastly, the structure and look of our reports are changing as well. 

All changes have been instituted to more clearly express and report the issues that are occurring in the homes we work in.  We need to know if you agree, so please let us know if you see areas for greater clarity.

Thank you!

Colorado Springs is on the Move to a New Compliance Code

What does this mean for you?

Regional Building Department (RBD) is bringing the 2015 codes and the International Energy Conservation Code to El Paso County.

These code changes won’t require a complete overhaul for your current building process, because RBD has included flexibility in their adoption of the code, making the code transition meaningful, and adaptable at the same time.

Key things you need to know:

  • The code presents multiple pathways; selecting the best pathway is critical.
  • Building a 2×4 wall is a possibility, but you won’t be able to use the prescriptive path.
  • The simulated performance alternative allows trade-offs which can help you maintain your current energy specifications.
  • Through code compliance, EnergyLogic can generate your HERS Index score to help position and market your homes, and to help ensure that you receive eligible utility incentives.
  • Pikes Peak Regional Building Code Implementation Documentation Link

RBD is now accepting new plan submissions under the 2015 IECC.

  • New plan submission is required, which presents an opportunity to change building pathways.
    • Blower door and duct leakage testing are required.
  • New HVAC designs are required, which presents an opportunity to evaluate, and potentially change, HVAC designers.
    • Building cavities are not allowed as ductwork.

How can you best prepare?

EnergyLogic is well versed in the new code and is prepared to support our partners to make this transition as painless as possible. We understand that the path to a successful partnership means working together in all phases of the building process to ensure that everyone has input and is apprised of both cost-effective and flexible options to achieve code compliance.

If you have questions or would like to schedule a time to discuss pathways that meet your needs, please please email Robby Schwarz.

Building Homes to Meet Blower Door Requirements

Buyers of new homes expect their houses to be energy-efficient and comfortable, while also decreasing their costs on utility bills. EnergyLogic has not met a builder yet who does not claim to build a home that delivers on that promise. But how do you know how a house will perform if you do not measure the items which affect performance and comfort?

The 2012/2015 IECC Prescriptive Air Infiltration (Blower Door) requirement can present compliance difficulties and be a hassle for builders.

Why it matters

Undoubtedly, it costs money to heat and cool a home. Once we have paid to have the air heated or cooled, it makes sense to try to keep it inside the home, right?

Building Science tells us that heat moving with air through unsealed cracks, holes, and other openings is a much more significant source of heat loss (or gain) in a home than heat transfer through a solid wall or roof assembly.

This heat loss does not matter if it is up, down, left, or right; all there needs to be is an escape path, and since air is pretty small, it can get through the tiniest of openings.  To make the problem even worse, fibrous insulation (fiberglass) does little to slow this heat loss because the air carrying the heat can move through the insulation faster than the insulation can do its job.

Therefore, the holes between the inside of the house and the outside of the house need to be sealed with a material that will stop air movement. Stuffing fiberglass into a hole is not going to eliminate the problem. A blower door provides a quantifiable measure of how well this is being done.

Most common issues 

Our experience performing thousands of blower door tests has shown the most common issues for low performing results:

  • Foundation to the sill plate
  • Rim and box joists
  • The gap between framing and shaft liner walls
  • Poorly sealed penetrations between ceiling and attic such as canned lights and bath fans
  • Poorly sealed mechanical penetrations

Installing mechanical systems in garages and attics is like coming to the plate with 2 ¾ strikes against you, and architects need to be aware of this.

We have also discovered some surprising places where air can get into a house, such as poorly backfilled crawl spaces where air can travel through gravel and perimeter drains or through unsealed sump pits.

Adopting the code

Building homes to meet the 2012/2015 IECC Prescriptive Air Infiltration (Blower Door) requirement is here to stay, but adopting the code doesn’t have to be painful.

We believe the requirement helps to build a higher-performing home, making your clients happier and more comfortable, which may lead to fewer warranty calls.

EnergyLogic is an experienced consultant, positioned to help you understand why blower door tests are important and to help you to meet energy code requirements, while delivering a better product to your customers.
