In our Spring 2023 eMagazine, we're discussing all things sustainability. As the industry looks for ways to reduce greenhouse gas emissions, it is crucial to find ways to reduce the carbon footprint of precast concrete wall panels without losing the performance characteristics. Browse our articles to read about topics such as reducing carbon in precast wall systems, achieving the proper airtightness of buildings, and how metal roofs are leading the way toward energy efficiency. Our CE Article this issue revolves around high-performance cold storage roof design.

The developers are aiming for LEED Platinum Certification, as well as compliance with Toronto Green Standard (TGS) requirements. In effect since 2010, the TGS sets tiered energy, emissions, and sustainability benchmarks for new buildings to support Toronto’s goal of reducing greenhouse gas emissions to net zero by 2050.
Companies have several options for decarbonizing cement. About 20 percent of the reduction will come from improved operational measures such as energy efficiency. The rest of the reductions will come from technological innovation.
Building airtightness continues to grow as a design consideration or requirement in most modern building designs. However, due to the complex nature of architectural design, building components, system options, involvement of multiple trades, and the pace of modern construction, achieving airtightness in a building is often easier said than done.
Cold storage buildings are exceptional structures because they experience extremes in both internal temperature and humidity compared to typical buildings. Due to their distinctive nature, cold storage buildings require unique construction assemblies, including roof assemblies.
In the fight against the impacts of climate change, evolving building codes, performance standards and building practices are being utilized to improve sustainability, resiliency and efficiency—all key components in trying to meet the goals of the Paris Accord and achieve net-zero carbon by 2050.
The profile of specific components, their configuration or sequencing, can vary with the roof system, climatic differences, and regional or area practices. Dimensions as shown are recommended minimums and are intended to be approximate to allow for reasonable tolerances due to field conditions. Flashing or stripping ply should extend into scupper throat, and be fully welded
