Multifamily reference building

The multifamily reference building was defined at the SPF and represents a house with 6 apartments typical for Switzerland. The consumption data and user behaviour were defined taking into account current standards and studies. The building is available in two versions with different thermal insulation. The building was used in several national and international studies and is freely available for further use.

 

Recommendations in a nutshell

 

SPF Info (USB stick in credit card format)

The SPF Info contains a comprehensive collector catalogue (with collectors tested at the SPF institute) as well as a variety of software tools, demo programs and a vast selection of current SPF publications.
 

SOLIND Tool – Pre-feasibility study solar thermal in industry

The free SOLIND Tool for Excel enables you to perform a quick and rough feasibility study for the use of solar thermal energy in industry. The tool was developed in cooperation between Swissolar and the two institutes SPF and Lesbat as part of the Sol-Ind Swiss project and financed by Energie Schweiz and the energy agencies of the cantons of St. Gallen and Vaud.
 

GainBuddy – Gross solar yield calculator

GainBuddy is a program for the calculation of the gross yield of solar thermal installations. The yield can be calculated based on a selection of meteo data files or based on specifically measured meteo data input. The program can deal with time resolutions from seconds to hours. The software was developed at SPF and financed by the SFOE (Swiss Federal Office of Energy).
 

TubeCalc

TubeCalc is a useful (freeware) program that enables users to rapidly calculate pressure losses and flow conditions in collector and piping loops.
