It is often argued that great energy savings can be accomplished by upgrading existing energy-inefficient building stock. However, even if these investments are profitable at the time, it might be even better to postpone these measures as even better investments can be realized later on. Such behavior can be analyzed by applying the real options analysis (ROA) framework. In addition, the retrofit scenario differs from the new development case, as the former is affected by the value of the already existing building, since this value must be "surrendered" in order to acquire revenues from the retrofitted building. The main purpose of this paper is to evaluate green refurbishments using the real options methodology. In doing so, we are able to accurately estimate the "embedded" real option values of deferring green refurbishments, thereby adding to current explanations of the energy-efficiency gap. This paper also discusses policy suggestions to reduce the value of waiting and thus trigger these refurbishments today. QC 20160225 |
