Abstract

The performance renovation of existing school building stock is a crucial strategy to achieve energy and environmental targets at the national level since education building is the third largest energy consumer in the building sector. K-12 schools in the US represent approximately 8% of energy use and 10% of the ﬂoor area in service buildings nation-wide, spending more than $8 billion each year on energy. K-12 buildings are the suitable type of building for the application of energy efficiency and good indoor air quality measurement. The paper discusses the findings of an existing K-12 building from energy performance and indoor environmental quality perspective. An overview of research on existing K-12 building energy performance are provided and unique characters of K-12 buildings’ energy behaviors are identified. Then a set of most urgent problems are identified using a case study and a new framework and methodology for energy efficiency improvement are tested on the case study. The new energy efficiency improvement framework included three steps: firstly, the existing condition the building is measured and assessed; secondly, a set of optimizing and prioritizing scenarios are evaluated against baseline and benchmark using broad online database; thirdly, a set of performance renovation package is proposed based on energy simulation and life cycle assessment result.
