energy management

This study has dealt with the energy and CO2 management at the new Kyushu University campus. The new campus named Ito Campus is located west of Fukuoka city, JAPAN, and opened on October 1st, 2005. In this paper, we estimated the CO2 emissions of new buildings at the Ito Campus by using simulated data and construction data, as the first step to develop an energy and environmental management system. In the evaluation, we compared the CO2 emission at the Ito Campus with the existing buildings at the old Hakozaki Campus.

The EPBD prescribes an energy performance certificate for buildings. According to the nationalimplementations of the EPBD for non-domestic buildings the specific data of the building will begathered during the certification process and combined into a multi zone model describing buildingand building systems from an energetic point of view.

The study was to test five units used in single house mechanical ventilation systems with heat recovery. Tests were made according to CEN project prepared by CEN TC 156/WG2/AH7 including air tightness, pressure-airflow's curves and temperature ratios. A full test on frost and condensation was also realised on one unit to determine the influence of these parameters on performances. Test results, influence of wet or dry conditions and main conclusions for using these results in dimensioning, will be given.

The project of CEN Standard from the Ventilation for dwellings group TC156/WG2/AH4 [1]for airflows calculations is being submitted to enquiry.This method can be easily compared to AIVC guides to calculate the ventilation airflow(natural or mechanical) in a given status. Yet, for energy loss estimation, these airflowscalculations must be done either hour per hour, either with average values andsimplifications.

An innovative energy management program has been successfully implemented at Mount Isa Mines, Mount Isa. Situated in Australia's north-western Queensland, remote from any electrical grids, Mount Isa Mines, owned by M.l.M. Holding Ltd, relies on electricity generated through its own two power stations. In 1988- 1990 the company was faced with a pressing requirement to reduce both operating costs and carbon dioxide emissions.

In the district of Schwandorf a Dual Energy Management System together with various energy management adapted to parallel traditional remodelling were to be implemented beforehand in a total of 22 already existing buildings. The efficiency of these strategies with regard to energy consumption and comfort (i.e. thermal comfort of the occupants) was to be measured over a three year period. The subsequent evaluation was to result in recommendations concerning the design and operation of The EMS and the building facilities under the given conditions.
