NW Wind & Solar designed a special racking system that extends beyond the Bullitt Center walls to install 575 – 425 watt SunPower photovoltaic panels on the roof. It was calculated that the panels along with 20 SunPower inverters will generate more than 230,000 KWH of energy in an average year.
To be “net zero” energy, the Bullitt Center will generate as much electricity every year from solar panels on its roof as its tenants use. As part of the Living Building Challenge, the Bullitt Center will meter its energy production and consumption on a continuous basis and show the results in its lobby and on the web. Tenants will be allocated an energy budget based on the percent of the building they occupy. Tenants that remain within their budget will pay nothing for electricity.
We're delighted to share with you what some of the project stakeholders had to say about our work, and about working with us on this amazing project:
Northwest Wind & Solar approached the project as if they were the long term owners of the PV Roof Array at the Bullitt Center; true value. The PV Roof Array at the Bullitt Center is a challenging installation. And as one would expect there were unexpected challenges that arose all along the process, from design to installation. Kevin Charap’s leadership for Northwest Wind & Solar during all these challenges is unwavering which proved to the entire design team and general contractor that Northwest Wind & Solar is the company for PV installations.

As a six-story building in a dense urban setting, it was no small feat to design and engineer the aluminum racking system and install the photovoltaic array onto the Bullitt Center. So we needed a team of problem solvers and Northwest Wind and Solar delivered. Not only were they able to install the PV array, but they did so in a very cost-effective manner.”

Installation went very well. The racking was a challenge and NWW&S came up with a solution that was satisfactory. “The solar installation is an iconic part of the building that can be seen from around the city and makes it stand out in the Capitol Hill skyline.

Northwest Wind & Solar’s recommendations during the design/coordination effort really helped to streamline the installation of the PV panels. In fact, I believe that the mock-up frame that they constructed for the design team to review was a key piece of the puzzle!
