Objective
1) Design, building and evaluation of an estate of 259 houses ("Toolenburg 19") as a passive solar (and telework) reference estate for the next neighbourhood in Haarlemmermeer.
2) Use, evaluation, and modification of the design tool PASCAUD (Passive Solar in Computer Aided Urban Design).
3) Development of additional energy/environmental investment strategies by exploring the possibilities of telework and location independent work in general.
Preparation of a planning guide to address solar and telework issues in the design process of town extensions.
The preliminary results of the project are :
(1) design and construction of the solar oriented neighbourhood Toolenburg 19,
(2) an energy evaluation of Toolenburg 19 with a partially upgraded version of the design tool PASCAUD, and
(3) a scenario study plus 'Planning Guide' to address solar and telework issues in the design process of town extensions and
- the Preliminary Final Report with an assessment of the win-win strategy that the proposed solar/telework combination can provide for both the environment and the economy of a region.
Toolenburg 19 was under construction since April 1994 and completed in November 1995. A detailed overview of the design and energy investments is part of the Technical Annex of the project.
PASCAUD has been used to evaluate a representative number of the designed houses of Toolenburg 19. The results indicate that the design meets the Passive Solar Effectiveness Norm, drawn up during the planning phase of the project. This means that the actual design comes within 90% of the energy performance of a design with all of the houses oriented on due south without shading from obstacles. The actual effectiveness is 93% for a representative selection of 20 houses. The two main areas of concern are (1) the data formats of PASCAUD in relation to the architectural drawing conventions and (2) the necessity to overhaul the PASCAUD software due to the change of the residing CAD programme MicroStation to Version 5 (the overhaul would also solve the data format problems).
The scenario study has been discussed in a workshop with a number of actors in the region. The results of the workshop have been evaluated and are incorporated in the published study.
The Planning Guide incorporates the scenario study and the lessons from Toolenburg 19 and is aimed at adressing solar and telework issues in the design process of town extensions.
The preliminary Final Report is aimed at answering the question how investments in solar oriented houses can be made attractive on the open market. To this end, the solar/telework combination is explored on its potential to provide the win-win strategy for a sustainable competitive development in a region. To assess the strategy, the solar/telework combination is placed in the context of a sustainable competitive development in general. From thereon, the attractiveness of the concept is explored for the sustainable and competitive development of Haarlemmermeer's largest and most environmental sensitive industry, the air transport industry of Schipol Airport. Therefore, airport challenges are identified, such as commoditisation and congestion avoidance. And industry initiatives on telework and related teleservices are distinguished. Subsequently, emerging technologies are put forward, that can help alleviate the constraints of present concepts of telework and teleservices. In conclusion, recommendations are made to bridge the gap between local industries, towplanning and other actors in the field.
The project is to create a stepping-stone for the integration of passive solar concepts in the regular design practice of towns and cities. Since 1981, the municipality of Haarlemmermeer pioneered this integration by applying the concepts to some of its housing projects, and by helping to develop the computer program PASCAUD. Passive Solar in Computer Aided Urban Design. The municipality is designated to develop new project of 17500 houses, with construction starting in 1996. The project's Toolenburg 19 is part of the last batch of the town extension that is currently being finished. The 259 houses are designed in 1992/1993 and construction finished in December 1995. The project builds upon : 1) a feasibility study on passive solar in '81/82, 2) an experimental "Energy Park" of 56 solar houses, and 3) the field trial "Overbos 8", one of the first large scale applications (275 houses) of passive solar concepts in the regular not extra subsidised building stream of social housing.Overbos 8 will serve as a performance standard for Toolenburg 19.
