2. Introduction Basic Requirements for a facade:
comfortable indoor climate
sound protection
good lighting
minimal energy input

3. Introduction A Double Skin Facade (DSF) can provide:
a thermal buffer zone
solar preheating of ventilation air
sound protection
wind protection with open windows
pollutant protection with open windows
fire protection
nocturnal cooling
aesthetics
site for incorporating PV cells

4. Project aims
Best Practice Guidelines based on a comprehensive survey of DSFs
Information on built examples of DSF office buildings
Confidence concerning operating performance investment and maintenance costs shall be increased

7. Bestfacade WP1 – State Of the Art
Collection of data on DSFs in different countries and climatic regions
Development of a coherent typology
Basic principles, history
Questionnaires investigating thermal be- havior, indoor air quality, comfort and user acceptance, energy demand a. consumption
Report on State Of the Art

8. Bestfacade WP2 – Non-Technological Barriers Two Phases:
Analysis of non-technological barriers Legal, Financial, Institutional, Standardization, Educational
Strategies to overcome these barriers
Results will be incorporated in the dissemination activities

9. Bestfacade WP3 – Benchmarks and Certification
Using results from WP1 a benchmark system have been developed
Building owners and operators may compare their energy consumption with other buildings
Advice and measures to reduce energy consumption will be offered

10. Bestfacade WP4 – Simple Calculation Method
For an assessment of thermal behaviour complex simulation tools are necessary
Extensive iterations are often required
No predictions on energy efficiency and user comfort in the early planning phase
Development of a monthly balanced calculation method
Reliable prediction on energy consumption in the early planning phase

11. Bestfacade WP5 – Best Practice Guidelines
Design guide with best practice examples
Providing basic scientific, technical and economic knowledge on DSFs
Case studies, potential advantages and disadvantages
Non energy related issues
Review of simulation tools

13. Bestfacade
The BESTFACADE project will actively promote the energy efficient concepts of double skin facades.
Information supporting the design of energy efficient and healthy office buildings equipped with DSFs.
Detailed practical information in order to design, choose, manage, use and maintain double skin facades.
