Temporal variations in the primary energy use and greenhouse gas emissions of electricity provided by the Swiss grid

Didier Albert Simon Vuarnoz, Thomas Bernard Paul Jusselme

It is a frequent practice nowadays to use mean annual conversion factors (CFs) when performing life-cycle assessment (LCA) of processes and products that use electricity supplied by the grid. In this paper, we conduct an hourly assessment of the greenhouse ...

Understanding building occupant activities at scale: An integrated knowledge-based and data-driven approach

Andrew James Sonta

Buildings are our homes and our workplaces. They directly affect our well-being, and they impact the natural global environment primarily through the energy they consume. Understanding the behavior of occupants in buildings has vital implications for impro ...

Low Carbon Pathways for Structural Design

Catherine Elvire L. De Wolf

To avoid an increase in greenhouse gas emissions, a depletion of resources, and waste accumulation, structural engineers have a major role to play in low carbon structural design. For example, cement- based materials represent one-third of all materials ex ...
