WS-10: BUILDING OPERATIONS & MAINTENANCE



WS-10: “How to get energy and cost savings during BUILDING OPERATIONS & MAINTENANCE workshop“

Energy IN TIME: Simulation-based control for Energy Efficiency building operation and maintenance[www.energyintime.eu]

Up to 90% of the buildings’ life cycle carbon emissions occur during their operational phase, mainly as consequence of the HVAC, lighting and appliances’ energy use. This phase also represents 80% of building’s life-cycle cost of which 50% is consequence of the energy use. Therefore, energy and cost saving strategies addressing the building op-eration phase have a major impact in the building life cycle cost. During the session, the innovations of the European project Energy IN TIME (EiT) that contribute to reduce costs and energy consumption during building operation will be presented, assessing their fu-ture relevance and performance, considering the maturity and needs of the market

During the session, the speakers will address the question from viewpoints of different actors in the building sector, such as representatives from industrial companies, RTD performers, specialised SMEs in the field of consultancy, building maintenance, or tech-nology providers.
They will report about the solutions investigated in EiT project and their application in four demo buildings with different typologies, uses and expected user behavior that have been selected to serve as testing places for the project by implementing innovative simu-lation-based control techniques aiming to reduce energy consumption and energy bill during their operation phase. Different climatic zones are also addressed as the buildings are located in Bucharest (Romania), Faro (Portugal), Helsinki and Levi (Finland).

The session will show real ways forward from demonstrations and lessons learnt into replication of the experience in non-residential buildings in Europe, which present the building typologies that guaranties higher impact and room for improvement due to the variety and quantity of facilities and equipment covered and the operational management model used. Design, energy management offices, investors and professionals form the building sector are targets of the session.

Project Introduction

Energy IN TIME is a Large-scale integrating project within the 7th Framework Programme FP7-NMP, Sub-programme EeB.NMP.2013-4, which brings together a total of 13 partners from 8 different European countries. The aim of the project is to develop a Smart Energy Simulation Based Control method which will reduce the energy consumption in the opera-tional stage of existing non-residential buildings, resulting in energy savings of up to 20%.

Intended Outcomes

Buildings Operational stage represents 80% of building’s life-cycle cost of which 50% is con-sequence of the energy use. Up to 90% of the buildings’ life cycle carbon emissions occur during their operational phase, mainly as consequence of the HVAC, lighting and applianc-es’ energy use. Therefore, energy and cost saving strategies addressing this building opera-tion phase will have a major impact in the building life cycle cost.

Energy IN TIME (EiT) project goes beyond existing building control techniques, developing an integrated control & operation approach, that will combine state of the art modelling tech-niques with the development of an innovative simulation-based control technique with the overarching objective of automating the generation of optimal operational plans tailored to the actual building and users requirements. This approach will allow reducing system ineffi-ciencies and contributing to improve building energy efficiency and comfort.

The target for Energy IN TIME solution will be existing non-residential buildings, which pre-sent the building typologies that guaranties higher impact and room for improvement due to the variety and quantity of facilities and equipment covered and the operational manage-ment model used in them. A control tool will be implemented in the building energy manage-ment systems to be automatically and remotely operated. The methodology for the enhanc-ing solution implementation will be defined for existing buildings and for its implementation in new buildings since its initial commissioning.

EIT Consortium Members

The Energy IN TIME consortium is made up of 13 partners from 8 different EU countries. EiT project, started in October 2013 and funded by European Commission, is developing a Smart Energy Simulation-Based Control method to reduce the energy consumption and en-ergy bill in the operational stage of existing non-residential buildings. The new techniques are based on the prediction of indoor comfort conditions and user behavior performance to improve the lifetime and efficiency of energy equipment and installations through continuous commissioning and predictive maintenance. A control tool will be implemented in the build-ing energy management systems to be automatically and remotely operated. During the session, four demo sites will give credible evidence of the benefits of the application of this innovative approach for buildings operation and maintenance.
