Description: The U.S. Resiliency Council (USRC) conducted a study on the comparative seismic performance of multifamily structures comprised of four construction types: traditional wood framing, cross laminated timber (CLT), steel framing and insulated concrete forms (ICF). The objective of the study was to demonstrate that different structural systems, all permitted within the International Building Code, may nonetheless deliver different performance in earthquakes. While a code compliant building regardless of structural system is expected to provide life safety, the amount of physical damage, repair costs and building functional recovery time can depend significantly on the strength and stiffness of the selected structural system.
The in the study, estimates were made on the repair costs and recovery times associated with damage caused by a range of earthquake intensities in various locations. These estimates were based upon methodology developed over more than fifteen years by FEMA in the P58 – Seismic Performance Assessment of Buildings standard. Furthermore, it estimates repair costs and recovery time based on the fragility of individual structural and nonstructural components. Ultimately, net benefits and net construction cost deltas were compared across the four configurations and potential return on investment was estimated considering earthquakes that might occur over a 50-year building life. The study concludes with a USRC rating for safety, damage and recovery for each system and territory.

Description: There’s a wide array of commercially available, proven technologies to deliver deeper energy savings cost-effectively. The energy efficient integrated systems approach often requires significant expertise to ensure that they are designed, integrated, commissioned, and operated effectively. Furthermore, the customary practice of building energy retrofits is to treat such projects as standalone engineering projects, which is often too disruptive to the building occupants and activities because they are not aligned with the real estate life cycle.
A scalable approach to deploying energy efficient integrated systems in offices and schools by opportunistically incorporating them within adaptive reuse projects ranging from tenant fit outs to whole building renovations is more productive. We describe a suite of Integrated Systems Packages (ISPs) that are ‘pre-engineered’ to minimize expertise and effort required for implementation. Each ISP is tailored to a particular project scope, such as tenant fit out, equipment replacement, whole building renovation, etc. Each ISP is also pre-validated with respect to functionality and energy performance to reduce real and perceived risk. We review ISP toolkits which include template specifications and other resources.
