The directive sets minimum efficiency standards The effect of these directives will very much depend on the way tor new buildings, introduces energy certification of buildings, they will be implemented and entorced on the Member Satet and establishes regular inspection of boilers and air conditioning level. According to the EC's own analysis, the above mentioned systems. This directive is accepted by the European parliament enery efficiency policies will account tor approx. 1 .5% energy and is already in place. As from january 2003 all member states savings compared to business-as-usual. What does this mean need to have legislation on minimum energy efficiency standards tor renewable policies? With additional savings on energy use and a certification system must be in place. oc af n1 . b5e%r epaecrhyeedawr iut hp 2t o5 %2 0l e2 s0s, ar esnheawr ae bol ef ea nr oeur gn yd c2a0p%a cri teyni en swt aa bl l el eds.
