Energy neutral retrofitting of apartment flats - modelling and detailing with consent of inhabitants

摘要

The Dutch policy for sustainable housing aims at refurbishment of existing housing complexes. The economical conditions for a successful redevelopment are lowest were the income of the inhabitants is lowest. However, the multi-storey buildings are technically easy to adjust to higher standards of insulation, glazing and ventilation. The energy consumption for heating drops drastically because of the optimal ratio between the surface of the walls and roofs adjacent to the outdoor climate and the heated volume. Calculations show that zero-energy for heating is technically feasible. If the social demands of the inhabitants are incorporated, studies show that inhabitants will not have any objections towards most of the techniques involved to reduce energy consumption due to transmission and ventilation. On the contrary, it will save them money yet it will increase their indoor air quality and thermal comfort.
