The existing Powerhouse 1 at 430 N College Ave #425, Fort Collins Colorado, is approximately 100,000 sf and the new building will be approximately 165,000 sf. The existing building and the new building will have similar occupancy types as they are both comprised of office spaces, conference rooms, a small number of large assembly spaces and miscellaneous lab/research spaces used by students/staff. Building is not intended to operate 24/7 similar to existing Powerhouse 1. The charts on the next page use calculations based on the existing building to extrapolate an average water usage per SF for a research and office building similar to that of Powerhouse 2. 351 LINDEN STREET, SUITE 100 FORT COLLINS, CO 80522 970 -232-9558 www.pec1.com Existing Building Usage The existing building uses its water tap for both irrigation and cooling through an evaporative cooling tower. The new Powerhouse 2 building will have a separate irrigation tap and will use other cooling methods that do not continuously consume water to produce cooling. A yearly water consumption from 2021 for the existing Powerhouse 1 building was provided to PEC by the owner. A snip of the yearly usage is shown below. The monthly average for months when the evaporative cooling and irrigation can be excluded are highlighted in yellow. Results Given the above data and the estimated flow, it is safe to assume the new building will follow a similar water usage per SF as the months that do not use irrigation or evaporative cooling. The average Gallons/SF/Month for the months highlighted in yellow is 3.021 Gallons/Sf/Year. Based on the new building area of 165,000 Sf the yearly water consumption can be estimated as roughly 579,500 Gallons.
