Abstract

Following regulation of the European Union, objectives were formulated to reduce energy consumption of the built environment in the Netherlands. For the stock of Dutch non-profit housing associations it was agreed to improve the average energy performance to an average energy index of 1.40 in 2020. This research assesses and gives insights in the progress to this objective for over 2.0 million dwellings of over 250 Dutch non-profit housing associations in 2017 and 2018. The assessment consists of an analysis of applied renovation measures, changes of the stock like new construction and demolishing, and clarifying characteristics of housing associations. It is concluded that large urban housing associations with adequate financial positions drive the improvement of the average sectoral energy performance. The improvement happens for a large part within the existing stock, mostly with traditional improvements like improved heating installations and improved insulation. Innovative solutions like: photovoltaic solar systems, combined heat and power systems, biomass systems, heat pumps and external heating, are responsible for a relative small part of the improvement within renovations. New construction and demolishing are also responsible for a relative small part of the annual improvement, but there is potential to improve this.

Highlights

The European Union agreed in 2008 on goals to reduce the impact of human activities on the climate by 2020 [1]
In 2015 the determination method of the energy index changed [8] and the related goal changed to an average EI of 1.40 for housing associations in 2020 [9]
In this paper, the progress of the improvement of the energy performance of the non-profit housing sector in the Netherlands between 2017 and 2018 is explained. This was done by looking at the relative contribution of sample changes, changes of the stock and changes in the stock to the improvement of the energy index combined with an analysis of characteristics of housing association themselves

Summary

Introduction

The European Union agreed in 2008 on goals to reduce the impact of human activities on the climate by 2020 [1]. In the Netherlands these goals were translated in several sectoral covenants. Non-profit housing associations in the Netherlands have a large impact on the built environment because they manage about one third of the Dutch housing stock, totalling 2.4 million dwellings. For the Dutch nonprofit housing sector, agreements were made in 2008 [2] and in 2012 [3], which lead up to the Dutch Energy Agreement in 2013 [4]. Amongst others it was agreed to improve the average energy performance of dwellings of non-profit housing associations to an average energy index (EI) of 1.25 in 2020. The energy index is measured with Dutch legislation on the energy performance [5] which is the Dutch translation of the European Energy Performance of Buildings Directive [6], [7]. In 2015 the determination method of the energy index changed [8] and the related goal changed to an average EI of 1.40 for housing associations in 2020 [9]
