The challenge
What Neutral Home needed to solve
- The client wanted a 40% cut in energy use and carbon within two years.
- All heating on site ran on electricity.
- HVAC systems were running 24/7, even when nobody was there.
- There were no renewables in place, and lighting, kitchens and local heaters were adding waste.
- Comfort for patients, staff and visitors had to stay high throughout.
