Engineers Newsletter PREVIEW: Building Performance Standards for Existing Buildings

In the 2024-Q2 Engineers Newsletter (EN), Trane applications engineer Scott Delo discusses ways to apply ASHRAE® Standard 100-2024 to the built environment.

Decarbonization: New options for existing buildings

One of our industry’s greatest challenges is to help reduce the energy and carbon footprint of the built environment. While building codes have focused mainly on new construction and major renovations, existing buildings present a huge opportunity for savings.

What you’ll learn in this issue

In this Engineers Newsletter (EN), Trane applications engineer Scott Delo helps readers understand and apply the requirements of ASHRAE® Standard 100-2024, Energy and Emissions Building Performance Standard for Existing Buildings. This standard establishes energy and carbon performance targets for existing buildings, creates requirements for operations and maintenance, and establishes common enforceable language for jurisdictions to adopt.

This issue of the Trane® Engineers Newsletter is now available to read or download
