On top of the low base-rent, the project developer will further reduce cost to residents by returning all but a small fraction of the utility allowance to the occupants, achieving the lowest possible total cost of residency through energy savings. Energy demand reductions approach 100% through meeting the PHIUS+ energy standard and the provision of on-site renewables.
