A Cost Efficient Method Analysis of Energy Efficient Improvement of Historic Buildings


ABSTRACT Although the materials used in historical buildings are ecological, they can lag behind today's building systems in terms of building performance values. This situation causes much more energy consumption in historical buildings. Not being able to reach the desired comfort level with excessive energy consumption causes negative effects in terms of ensuring the sustainability of these structures. Many studies are carried out in order to ensure energy efficiency, which is one of today's problems in historical buildings. However, the determination of low-cost energy efficient solutions with small interventions is important in terms of choosing the most appropriate methods. In this context, within the scope of the study, energy efficient applications from small interventions to larger interventions were selected in three historical buildings with different construction systems in different regions. The energy consumption data of these applications were obtained with the Design Builder program, and the energy and intervention application costs were calculated. The payback periods of the applications were determined with the calculated costs. Effective applications with reimbursement as soon as possible have been identified. As a result, applications that pay for themselves in a short time are presented as suggestions.
