The present paper reports on an ongoing monitoring project, the so called OEKOHAUSproject. It is a building that was refurbished from 1994 to1996 with the intention of creating an exemplary project for energy-efficient building technologies. For the 1990ies it features extensive insulation of exterior building parts, as well as (later added) energy-active systems like photovoltaic panels and solar collectors. In early 2012 a comprehensive monitoring system was installed. The measured data includes external climate data (solar radiation, temperature, relative humidity, wind speed and direction and precipitation), internal climate data (temperature, relative humidity, CO2-Levels) and occupancy in several rooms of the building. Additionally previous documented data about energy consumption and production was collected and processed for analysis (e.g. demand of wood pellets for heating). In this contribution, we report on recent advances of analyzing the measured data, as well as on interdependencies of the data that was collected before the measuring devices were installed (e.g. reduced Pellets consumption in years with high solar radiation). Furthermore, we look at the energy performance of this refurbishment project from today´s point of view concerning energy efficiency: Is the building still outstanding
concerning energy efficiency, or would today´s requirements for insulation of building elements further decrease
its energy consumption?
