Energy Storage in High Performance Buildings

Before PVs became affordable, excess solar energy was stored thermally. Energy storage, both thermal and electrical, aids grid penetration of renewables and builds resilience on-site. We’ll look at passive and active thermal storage in advanced buildings, either integrated with the structure or as remote storage. We’ll also look at battery storage in an off-grid project and hydronic storage in a proposed small commercial project and show via an interactive model the effects of varying PV and storage capacity, and how storage increases the percentage of solar energy used on-site. Lastly, we'll discuss the integrated design process required to deliver these buildings.

Learning Objectives:

  • Describe the grid generation issues inherent in widespread use of renewable electricity
  • Describe the benefits of using energy storage, both thermal and electrical
  • Compare the types of thermal storage and identify suitable approaches for a particular project type
  • Assess the effects of increasing storage capacity and PV array size and how marginal benefits per additional increment decrease
