SIMULTAN - Simultaneous planning environment for buildings in resilient, highly energy efficient and resource-efficient districts

Synopsis This project enables the opportunity for an essential energy efficiency increase within overlapping buildings, to achieve the objective of resilient cities and districts with respect to a high quality of life, resource sustainability and energy efficiency. The goal is a workable tool based on a multidisciplinary planning approach, to support the decision finding process in order to design both refurbishment projects and new developments within a highly efficient city.

Summary

Starting point / motivation

Previous scientific research projects have shown that there is a high potential for essential efficiency arrangement within overlapping energy systems. Due to the negative response for already built passive houses and low energy buildings, there is an increasing resistance for the use of new innovative systems. The expectations of both developers and residents have been disappointed. In general, all troubles within either the planning and execution of unexpected backlashes in an energy supply system, reflects back due to the loss of the general outline within a sophisticated energy system.

Contents and goals

The planning team for both high efficient building retrofits and generally new designs is still lacking a tool which enables an integrated planning strategy and consistency within the scenarios for the development of an energy supply and demand system. Power supply companies need a comprehensive and consistent planning tool for technological opportunities within the building sector by considering the general supply and demand behaviour forecast. The aim of the project is an optimal planning procedure for buildings and energy supply grids with respect to system backlashes.

Methodology and approach

This project proposes to use a systematic approach. In the initial scenario, the energy demand behaviour of city dwellers, will be established and based on that a further scenario to develop an urban energy supply strategy considering building technology opportunities.

To enable an integral and simultaneous planning feature for an ideal complex of buildings, a design environment will be established for an integrated planning process from the preliminary phase to commissioning. By implementing real validated data from urban energy system simulations, the performance of resilience of all aspirated building configurations can be determined.

The workability of this methodology can be verified by using already existing and well known districts. These suitable building complexes will be determined, all essential steps for new buildings or refurbishments are to be iterated and all technical arrangements for optimal efficiency increase will be shown. Essential methods for this realisation are decentralised generation, active demand side management and thermal activation of construction parts.

Expected results

The expected result is a workable tool based on a multidisciplinary planning approach, to support the decision finding process in order to design both refurbishment projects and new developments within a highly efficient city. Based on the understanding for the general system, new tariff models are to be established and solid solutions for the energy system of the future are being determined.
