Building physics and life cycle assessment calculations

FREE basic version !

Eco-Sai: The USai and Eco-bat software tools have been merged to facilitate the work of professionals in the building sector. The result is the first software that makes it possible to analyse the U value, thermal inertia and life cycle assessment of a construction (homogeneous and inhomogeneous). Its intuitive interface and our outstanding customer support will enable you to quickly generate reliable results and realize projects on time along with cost savings.

Eco-Sai makes it possible to simply and quickly evaluate the characteristics of a construction during the draft stage or the project phase. Eco-Sai also provides valuable data to support the decision making process in building renovation projects.

Eco-Sai is connected to the product databases of several major building materials suppliers through the materialsdb.org system.

Eco-Sai has different versions with the following features:

 

Free version features:
  • Project concept management
  • Heat transfer coefficient calculation for both homogeneous and inhomogeneous walls, including effects of in-floor heating and plane air cavities (SIA180, EN ISO 6946)
  • Connection to the materialsdb.org database
  • Results presented in both graphical and numerical form
  • Can calculate the annexes from the EN ISO 6946 (mechanical fixation and air)
  • Multilanguage capability: English, French, German, Italian

 

Additional features in the USai module:
  • The dynamic thermal characteristics of the wall are accounted for according to the EN ISO 13786 standard (damping factor, dynamic heat transfer coefficient, thermal admittance)
  • Calculates the risk of internal condensation and the quantity of condensate according to the EN ISO 13788, EN ISO 6946 and SIA180 standards
  • Life Cycle Assessment calculation following the SIA2032 standard
  • Includes the Meteonorm monthly database which provides worldwide meteorological data to support the condensation calculations
  • SIA2028 meteorological data (monthly data)
  • Windows calculations
  • LCA materials calculations

 

Additional features in the ECO module:
  • Building grey energy evaluation following Minergie-ECO® (2016,2013,2011), DGNB, SNBS, SIA2040 and SIA2032 standards.
  • Eco-Sai can calculate the environmental impact of materials. This is done in a step by step manner as mentioned in the ISO 14040 standard and following
  • Eco-Sai allow to calculate the impact of the transport from the manufacturing plant to the construction site.
  • Technical system environmental impact (heat generation and distribution facility, sanitary and electrical installations, ventilation systems, thermal and photovoltaic solar collectors).
  • Eco-Sai can calculate energy - related impacts. The following six consumption categories can be configured: heating, domestic hot water, climatisation, ventilation, lighting and electrical equipment
  • Energy predimensioning. Users that do not have an energy simulation software can use the energy predimensioning Eco-Sai module.
  • Four reliable indicators for quantifying environmental impact: NRE, CED, GWP, and UBP.
  • Numerical and graphical results
  • Easy building comparisons
  • Impressions of graphical and textual reports

Supported operating systems: Windows 7, Windows 8, Windows 10, .... Use on a Mac OS X system possible with a Windows emulator (ex. Parallel Desktop see FAQ).
