One of the newest developments planned for the Hyde Park area and one of the most interesting additions to the Chicago skyline, is Solstice on the Park, a 26-story residential tower, offering 145 apartment units.
This unique glass and steel tower is literally shaped by solar access and will become one of Chicago’s greener residential buildings and the largest new condominium development in Hyde Park in more than 15 years.
The surface of Solstice on the Park has an optimum angle for 41.5 degrees north, that maximizes passive solar warming potential during the winter while keeping the sun out during the summer thus reducing cooling needs.
The completion of the project is planned for late 2010. 
There is also a business club, conference centre, gym and pool on the top floor. The building has been designed to maximise natural ventillation and air circulation. A glass void shaft is located at each end of every floor. This void contains a green skygarden every third level. This wintergarden provides an outlook for the internal users at each end. These areas also have shared break out rooms for each level. 
These spaces contain meetiong rooms or common areas. The voids are surrounded by glass louvres to allow natural ventialltion to flow to the sky gardens and the communal spaces. The facades are articulated with a solar screen. The screening consists of perforated aliuminium panels. These panels allow for the maximum transition of natural light, but provide shading from solar heat gain and maximise views.
