This feature article discusses the evolution and challenges of building energy codes, emphasizing their impact on the glass industry and energy efficiency.
Here is an overview:
Building Energy Codes
- Designed to improve energy efficiency in buildings, reducing energy demands and environmental impacts.
- Buildings account for 40% of total U.S. energy use and 35% of carbon emissions.
- Energy codes drive adoption of energy-efficient glass products, enhancing modern architecture.
- Critics argue affordability concerns hinder the implementation of stricter energy standards.
Push Back Against Energy Codes
- 15 states, including Missouri, have challenged new energy standards due to affordability issues.
- Legislation introduced to limit local governments' ability to enforce stricter energy codes.
- Concerns about housing affordability and rising construction costs are central to the debate.
Impact of Energy Codes
- DOE estimates model energy codes could save $182 billion in energy costs and avoid 745 million metric tons of carbon emissions.
- States like South Carolina and Oklahoma have not updated energy codes in over 16 years.
- Some areas see a decline in building permits after adopting stricter codes.
Industry Response and Future Directions
- The glass industry advocates for an "envelope-first" approach to building design to enhance energy efficiency.
- Collaboration between glazing experts and HVAC professionals is essential for effective energy modeling.
- Increased funding for code enforcement is necessary to ensure compliance and effectiveness of energy codes.
