    Sustainable Conservation of the Historic Built Environment
    Sustainable Conservation of the Historic Built Environment
    Explore the intersection between the heritage conservation and green building movements, both of which contribute to sustainable development. Heritage conservation promotes the ethos of stewardship; defining what is significant about the built environment; methods of extending the service-life of buildings; the value of maintenance and repair; and effective means for adaptively re-using buildings. Green building promotes holistic design; responds to the urgency of climate change and the need to reduce greenhouse gases; and encourages us to look at new systems and technology. By exploring the a variety of approaches to conserving the built and natural environments, students will be able to identify and differentiate between methods for assessing sustainability, develop appropriate metrics, apply evaluation tools, and determine appropriate treatments to improve projects.
