In my minor 'Renovation and Transformation' in Rotterdam, we did a project on sustainability, where we renovated an existing home (on paper) up to the standards of active house. This means that the design/renovation not only takes energy efficiency into account, but also the environment and comfort. For example, by improving insulation and installations, we managed for this home to run for 79% on renewable energy, and made sure all areas receive enough daylight.
