| Project Detail |
HESTIA addresses the need for implementing carbon removal strategies by converting buildings into carbon storage structures. HESTIA is also important for nullifying embodied emissions. The majority of these emissions are concentrated at the start of a building’s lifetime and locked in before the building is ever used. This upfront emissions spike equals 10 years of operational emissions in a building constructed to meet standard code, but increases to 35 years for more advanced, higher operating efficiency buildings, and more than 50 years for high-efficiency buildings operating on a lower carbon intensity grid. These time horizons go beyond 2050 climate targets, which means embodied emission reduction strategies are a high priority.
Project Innovation + Advantages:
Clemson University will develop a mass timber floor system alternative for greenhouse gas-intensive floor and ceiling materials, which account for up to 75% of embodied energy in traditional building designs. Mass timber products are comprised of thick, compressed layers of wood and used to create strong, structural load-bearing elements. The proposed system will address the entire building life cycle, from design and construction, through occupancy and operation, and contribute toward closing the gap between observed and theoretical service lifetimes. Carbon stored in the timber floor (and taken out of the atmosphere) will offset carbon emitted during production and construction of other building materials. By designing for de/re/construction, the proposed system will allow building components to have a second life instead of demolition and disposal.
Potential Impact:
HESTIA projects will facilitate the use of carbon storing materials in building construction to achieve net carbon negativity by optimizing material chemistries and matrices, manufacturing, and whole-building designs in a cost-effective manner. |
