Reinberg is a pioneer of ecological building and solar architecture. Even before he set up his practice, he had been involved in numerous research projects on architecture and ecology. Since 1990, he has been managing the practice jointly with his wife Martha Enriquez Reinberg.

The buildings benefit from the expertise the architect has gained through his research, and are characterized by an inherently designed sustainability that also carefully takes account of the needs of users and inhabitants. He completed numerous housing projects, refurbishments, public and corporate buildings to the maximum satisfaction of the users.

His success is evidenced by prizes and teaching activities abroad and at home. His integrated design approach has created a specific architectural language that is evident in his buildings.
