4. Annexes
Please follow the instructions given in the General Assessment Guide while documenting building
performance.
Basic & Quick Assessment
Short English explanation of the performance achieved with reference to the documents used as reference
when easily and quickly accessible documentation possible (see Complete Assessment).
Both, availability of daylight throught the building and availability of daylight in regularly used
work areas, are good scored, because of rather good architectural solution. View to the outside is
also, in spite of absence of regulation, quite well scored. Preventing glare was solved in classical
way (sunblind), due to absence of regulation. Colour rendering was out of architect’s scope, due
to absence of regulation.
=============================================================
