[ 97 ] 6 Morgenstond Midden, The Hague 6.1 Introduction This chapter concentrates on the Morgenstond Midden case study. In this part of the report we intend to explore renovation solutions for Morgenstond Midden and the costs, the extension of the functional life-cycle of the build- ings, the role played by sustainability in the planning process for Morgen- stond Midden and the relative involvement of performance agreements. Sec- tion 6.2 deals with the renovation solutions and the costs. In Section 6.3, we discuss the functional life-cycle of the buildings. Section 6.4 looks at the development of the plan and the planning process. Section 6.5 assesses the emergence of sustainability ambitions and ascertains which performance agreements – if any – were reached during the planning process. Section 6.6 reports on the experiences of the main parties regarding performance agree- ments and discusses the opportunities and risks envisaged by the municipal- ity and the housing association. Section 6.7 describes the experience of per- formance agreements for sustainable building. 6.2 Energy-efficient renovation The research focuses on the Hengelolaan complex which was built in 1954. This complex includes two buildings: Complex 01 and Complex 02. Complex 01 is a four-storey apartment block with 56 dwellings and Complex 01 is a three-storey block with 36 dwellings. Both have unheated, partly sunk base- ments which are used for storage. There are interior staircases and two apart- ments on each floor. These complexes have been selected as a case study because it is here that the plans are furthest developed. The field of study is presented in Chapter 3. The energy evaluation was conducted with the EPA tool ( Energie Prestatie Advies ). The calculations were subject to the following assumptions and constraints: n The buildings are free-standing with exposed facades. n The structure is based on the reinforced concrete load bearing, the so-cal- led Tramonta system. The cavity walls have a structure of concrete, air space and bricks with no insulation. The roof is uninsulated and slightly sloping with concrete and wooden constructions. The floor is uninsulated and made of reinforced concrete. n Double glazing was installed in an earlier renovation. n The energy demand is dominated by the use of natural gas for heating space. The calculations are based on local gas systems. Natural gas is also used for hot water (an instantaneous boiler in the kitchen) and cooking, electricity is used for other energy services. The buildings have natural ven- tilation. n The estimated annual average indoor temperature is 15 degrees.
