Redesigning the way the hospitals use energy can achieve a 60% reduction in energy usage, a new study carried out in Washington, US, has found.

The study, called ‘Targeting 100! Envisioning the high performance hospital: implications for a new, low energy, high performance prototype’, said a newly constructed, code-compliant hospital can save around $730,000 per year.

The key to efficiency is to integrate energy strategies, such as heat recovery, daylighting and thermal energy storage, at the beginning of a hospital project, according to researchers.

The study was conducted by design firm NBBJ in association with the University of Washington’s Integrated Design Lab.

The Northwest Energy Efficiency Alliance (NEEA), which campaigns for changes to energy-related business practice in northwest US, provided most of the funding for the project through its BetterBricks initiative.
