Summary
The Resource saving project in Geislingen is part of the ENERinTOWN project supported by the IEE Programme of the European Commission. It was developed for 80 facilities in the City of Geislingen and is based on an interdisciplinary approach involving all groups of building occupants. The EMS (Energy Management System) builds on an innovative web-based tool for distant reading of electricity, heat, gas and water meters and provides data analyzing capabilites and automated generation of energy consumption reports.
The main benefits for the city are: additional financial resources / implementation of a professional energy management / practical lessons on the responsible use of energy and resources for users/pupils.
No cost and low cost measures reduced the energy bill of public buildings in Geislingen during the first two years of the project by 340.000 . These are re-invested mainly in energy efficiency measures and in consulting and training. In this way the project is self-financed by the savings.
Results
Savings:
2004/2005: about 140.000 Euro, or 8 % of total energy cost
2005/2006: about 200.000 Euro, or 12 % of total energy cost
Annual Contest October 2006 for the year 2004/2005
Prizes for the best housekeeping: Two additional schools had savings of more than 15 % although project work was still slow. Therefore the caretakers earned all the merits.
Lindenschule Savings: 19,69 % = 25.798,15
Helfenstein-Gymnasium Savings: 15,27 % = 16.030,45

Lessons learned and repeatability
The project shows the considerable potential for savings of resources and costs in public buildings. The tight budgets of municipalities often do not allow the investment in costly electronic heating control systems or improvement of the building envelope like insulation of outer walls or refurbishment of windows.
As there are no initial or additional costs for the consulting or for the implementation of technical measures the threshold for the administration is very low to engage in this kind of projects.
A crucial point for the success of the project in our experience is the active involvement of the administration and the politicians to carry through the first phase of change in user behaviour which often causes some strong feelings on the side of the building occupants. The annual contest with press coverage is a most important tool to improve the interest of the involved parties.
The reinvestment of the savings should be made as early as possible to earn the profits from the savings for as long as possible. The minimum project duration should be 5 years because the 3rd year is usually quite critical as the commitment slows down after the first successful 2 years.
The concept can be replicated nearly anywhere in Europe where energy cost plays a major role in public buildings. Adjustment to the local conditions would be required. A certain critical mass of buildings and energy cost is necessary to allow for the remuneration of consulting work out of the savings which is more or less similar for a lower number of buildings.
