Tittle:
Evaluation method of energy efficiency and the open market value of residential buildings
Summary:
A German university of applied sciences and arts conducted a project to evaluate the relationship between energy efficiency and the open market value of residential buildings. Methods to calculate the benefit of energetic refurbishment of buildings have been developed.
The researchers are looking for industrial partners interested in technical cooperation or in-house research, and for partners from academia interested in joint research projects on the topic.
Description:
The development of methods to calculate the benefit of energetic
refurbishment of buildings was part of the project conducted at the German university of applied sciences and arts.
The energy efficiency of buildings is used to identify the sale value. The developed methods for the analysis of buildings can be used by authorized experts from the industry, i.e. from real estate industry, and by communal or municipalities authorities, state construction management etc. These potential partners are offered technical and research cooperations to exploit the developed technology and/or to develop further industrial applications, in-house research is also possible.

Details of the technology offered:
The economical view of energy-saving features and characteristics of buildings is of increasing importance when one considers the present ecological, energy and construction industry developments.
The analysis of the methods and procedures available demonstrated that helpful approaches for the establishment of the value influenced by energy-saving could be taken from the area of dynamic cost effectiveness investigation.
Carrying the title "en - DCF" (energy-saving Discounted Cash Flow method), a model taking energy-saving aspects into consideration was designed, following the capital value method. The en - DCF - model works with discounted energy cost savings as opposed to typical standard values of the year of construction.
In order to be able to render value development statements meaningfully plausible, a procedure with the title "Energineer" was developed for cost effectiveness investigations based on construction components´ life cycles.
Set at this point, the method developed with the title "EmA - NHK" (energy-saving modified fitting standards of normal production costs) provides suggestions of procedures that integrate energy-saving parameters into the existing procedure to establish the property value via normal production costs (NHK), according to the guidelines to establish the value of property (WertR).
As an additional flanking measure, a system based on the surface area of a building´s ´envelope´ was designed to establish energy-saving modernization costs. Empirically established statistical values of energy-saving modernization costs from the evaluated modernization objects formed the data set used for this.
The band width of the empirically established, final energy-saving extent of change in value w´ lies between 0.81 - 0.94 -Y-euro; per more efficient kWh/m2 p.a. (multi-family house) and 1.10 - 1.26 -Y-euro;/kWh/m2 p.a. (semi-/detached house), depending on the type of building, use and building classification.
The values confirm the change in value w´ which can be deduced via en - DCF, and exemplarily via the EmA - NHK - model.
Advantages and Innovations:
For more than 15 years the importance of refurbishment of buildings rises. Exact knowledge of the value relevant characteristics is the base of successful project development of realty. Environmental and energetic qualities are and will be important for decisionmaking concerning rentability, operating costs and resale value. The offered methods are efficient evaluation tools.
