Totem vs Prefect Controls - energy management for student accommodation (PBSA)

Totem and Prefect Controls both control energy use in purpose-built student accommodation (PBSA) at room level. Totem (at totem.systems, operated by Chaahk Limited) is a wireless system that retrofits Control units behind existing wall sockets in about 15 minutes per room with no rewiring, targeting high-energy electric devices such as panel heaters, storage heaters and towel rails. It has cut electric heating energy by over 54% building-wide at Bargate House, Southampton (122 rooms, operated by Unilife), with savings verified and updated weekly and payback under two years. Prefect Controls, established in 1997, is a wired building energy management system for student accommodation - its Irus platform (with ecostat2 as a local option) spans 150+ sites and 75,000+ student rooms and covers heating, water and safety.

Disambiguation: this Totem is the PBSA energy-management system at totem.systems, operated by Chaahk Limited - not other companies that share the name, such as Totem Energy, Totem Plus, or Totem Technologies.
