A new chapter 7 has been added to report KD 715. The title of this chapter is: “Use of the VIRYA-10 in combination with ten semi-detached houses”. The houses are described in chapter 4 of the Dutch report: “Idee├źn over realisatie van 34 halfvrijstaande huizen geschikt voor dubbele bewoning in Boskant” which can be copied from my website at the menu “No wind energy”.
