This webinar, which is part of DOE's Building Energy Codes Program Energy Codes Commentator webinar-based training series, highlighted some of the major changes that you can expect to see in building envelope, mechanical system and lighting requirements of ASHRAE Standard 90.1-2019. In addition, the session highlighted the whole building performance paths, Energy Cost Budget and Appendix G and new commissioning requirements. This session is for anyone who wants advanced insight into the new Standard’s expected impacts on the industry.
The DOE Building Energy Codes Program hosted a webinar-based training series called the Energy Code Commentator. The series spaned a variety of special topics of interest to all energy code stakeholders--for both residential & commercial buildings. Check out the lineup and recordings of past events!
This session explored the relationship between home envelope tightness and energy performance and the policy implications of stronger energy code requirements. Focus was given how to attain tighter envelopes and the impact of envelope tightness on HVAC load calculations, the relationship between envelope tightness and intentional ventilation, and a few lessons learned from the Duct and Envelope Tightness (DET) verifier program. New technologies and approaches enter the marketplace every day. This session was designed to help policy makers, builders, designers and code officials identify current code requirements, best practices and missteps to avoid when creating tighter envelopes and considering new code requirements.
This webinar provided an overview of the basic functions of the REScheck software. It covered how to identify the construction specifications needed to complete a compliance calculation, how to enter building thermal envelope components into the software, and how REScheck calculates compliance. The webinar also covered the details displayed on completed compliance reports, inspection checklists, and panel certificates, and what they entail.
This webinar provided details on the requirements for lighting in the 2015 IECC and ASHRAE/IES 90.1-2013. It explained each requirement and provided useful examples that help clarify potential application variations or issues. The information provided will supply the user with a better understanding of the intent of the requirement and what would be considered appropriate compliance vs cause for non-compliance.
This webinar provided an overview of the basic functions of the COMcheck software. It covered how to identify the construction specifications needed to complete a compliance calculation and how to enter building thermal envelope components and lighting and mechanical systems into the software.
This webinar covered the requirements of the Energy Rating Index (ERI) compliance alternative performance path that gives builders yet another option for complying with the International Energy Conservation Code (IECC). In addition to the prescriptive and performance paths of previous versions of the IECC, builders now have the option of meeting a target ERI score through a wide range of performance options to demonstrate compliance. This event also covered how the new compliance path can be implemented into current plan review and inspection processes for Code Officials and resources available to assist with construction best practices.
This webinar provided an overview of common commercial building Heating, Ventilating, and Air-conditioning (HVAC) systems as they relate to energy code requirements. It covered the most common HVAC systems and equipment, along with energy-related components and controls. Several important energy code requirements were reviewed, including what to look for in the field or on plans.
Daylighting controls reduce artificial lighting in response to sunlight coming in through windows and skylights. They were first introduced in ASHRAE Standard 90.1-2010 for commercial buildings and are now part of 90.1-2013 and the 2015 IECC. This webinar reviewed the fundamentals of daylighting, described how daylighting controls work and save energy, and reviewed daylighting control requirements in the latest codes and standards. It also discussed how these controls should be implemented and commissioned.
Commercial energy codes and compliance are critical tools for increasing efficiency in new commercial buildings. However, assessing commercial energy code compliance can be a complex and costly endeavor. In addition, previous studies that included a narrow emphasis on a binary assessment of code compliance fail to provide meaningful feedback that could be used to design better code initiatives and more effective enforcement efforts. This webinar described two recent studies that have attempted to develop a deeper and more meaningful assessment of commercial building code compliance.
ANSI/ASHRAE/IES Standard 90.1, the Energy Standard for Buildings Except Low-Rise Residential Buildings, has been a benchmark and national model code for commercial buildings for over 35 years and is indispensable for engineers and other professionals involved in the design of buildings and building their systems. Now, with many new addenda incorporated since the 2013 edition, Standard 90.1-2016 will significantly change the way buildings are built as these new modifications find their way into the world's energy codes.
This webinar highlighted some of the major changes that you can expect to see in building envelope, mechanical system and lighting requirements. In addition, the session will highlight Appendix G, a new compliance path that enables a single, simple performance-based option for both minimum code requirements and above-code programs. This session is for anyone who wants advanced insight into the new Standard’s expected impacts on the industry.
