ETFE as climatic envelope – new greenhouse, The Botanical Garden Aarhus

Education
 
Description:         
Greenhouses are niches within the construction industry. In the Building Regulations, BR10, greenhouses are exempted from section 7, regarding energy consumption, but in a time with extensive focus on energy savings, how can the energy consumption in greenhouses be reduced? One of the options is ETFE. ETFE is a transparent plastic foil material with many benefits in comparison to glass which is usually used in traditional greenhouses. 
 
Based on the building of a new greenhouse in the Aarhus Botanical Garden, called Palmehuset (palm house), the ETFE building envelope’s impact on effect and energy demands and indoor climate has been examined. For this purpose, the weather data file in BSim2002 has been used to outline the effect balance. The purpose of this examination was to find the best combination of the ETFE building envelope for the mentioned parameters.
 
Areas of work:
  • Comparison of ETFE with glass in correlation to thermic and optical features.
  • Outlining of the effect balance for Palmehuset.
  • Analysis of effect- and energy demands, indoor climate and the financial aspects depending on the composition of the ETFE building envelope.
  • Weighting and selection of a recommend solution.
  • Analysis of the optimal location of the solar screening print on ETFE cushions.
  • Calculation and description of the ventilation- and heating principles.
