The House of Lebanon project required the restoration and adaptive reuse of an historic school campus to meet the needs of an affordable housing program for independent seniors. The project was subjected to rigorous Historic Preservation requirements and used Enterprise Green Communities 2011 criteria to meet energy conservation and sustainability requirements.

To successfully navigate this challenging process, the owner and the design team had to work with multiple federal and local Historic Preservation stakeholders; this integrated approach allowed them to implement the best green building practices applicable to the project. In addition, the development of the program required the engagement and support of the community.

This course will demonstrate how a balance of preservation requirements and sustainability goals was achieved to create new, sustainable apartments for seniors in Washington D.C.


After this session, participants will understand:

  • The expertise and resources necessary to evaluate and sustainably rehabilitate a National Historic Landmark structure.
  • The ways in which Historic Tax Credits and Enterprise Green Communities Criteria affect the design and planning of the rehabilitation of an historic structure.
  • How the House of Lebanon case study exemplifies design flexibility needed to establish the preservation and energy conservation goals for a project.
  • How design concepts can be developed to align with green building practices and preservation objectives.
