CAMPUS21: ICT tools for energy efficiency in campuses

Campus 21 addresses the need for integration strategies of ICT in building and neighbourhood energy management systems to achieve optimised and holistic operation of Energy-, Security-, Safety and other Facilities Services aiming to optimise the energy usage and operational cost and to reduce the overall CO2 emission of buildings and public spaces. The integration strategy to be developed will address four key areas

  • a technical strategy,
  • business and procurement models,
  • a validation concept, and
  • a standardisation concept.

The following Scientific and Technological Objectives (STO) have been identified in order to achieve the main objectives:

  • STO 1: Creation of concepts for new Business
  • STO 2: Development & Performance Evaluation of Buildings & Public Spaces
  • STO 3: Development of an Integrated Energy Systems Management Concept
  • STO 4: Development and Deployment of an ICT Service Platform for Energy Systems Management
  • STO 5: Development of predictive systems control, and load balancing
  • STO 6: Determination of a “Performance Baseline” (m16, WP2) and evaluation of “Advanced control tools
  • STO 7: Development of a Procurement Schema and widespread dissemination
  • STO 8: Development of a Standardisation Plan

CAMPUS21 approach

The key technological innovations of CAMPUS 21 are:

  • integration concepts for energy management systems (WP3) including the related middleware components (WP4),
  • methodologies for intelligent, optimised control of building services systems (WP5), and finally
  • algorithms and tools to support load-balancing between renewable micro-generation, storage systems, and energy consuming devices in buildings and public spaces (WP6).
CAMPUS21 approach

This is complemented by the development of key business elements, including:

  • new business models for integrated energy management and the underpinning novel procurements schemes (WP1), and
  • the development of Performance Metrics and a holistic Evaluation Concept for Systems Integration (WP2)

Work packages

Work package 1

WP1 methodology

CAMPUS-21 will develop, deploy, and test ICT Service Platform for the integration of existing ICT building subsystems including Building Management Systems (BMS) and Energy Management Systems (EMS), occupancy monitoring and external context systems (e.g. weather information, power grid congestion) in a single integrated control system.

WP1 addresses the Scientific and Technological Objective STO-1 defined on Creation of concepts for new Business Models and Procurement Schemes for Development and Deployment of the Integrated Energy Management Platform. The objective of this work package is to find out what kind of novel business models can allow robust risk-benefit-sharing resulting from the integration of previously isolated/ stand-alone energy management, control, monitoring, and security systems. Obstacles in the procurement process of integration components will be identified and documented.

Work package 2

WP2 DataWarehouse

This work package focuses on the development of concepts for monitoring and validation of building performance with an emphasis on Systems Integration Instruments to produce the evidence of energy savings, and total cost of operation. The as-is status in the different demonstrator campuses is documented and compared to the requirements on future integrated monitoring & control systems (D2.1).

A monitoring concept (and a corresponding data acquisition schema) defining the information required to analyze and evaluate buildings in view of different performance criteria is developed (D2.2, D2.5).

Different infrastructures and data acquisition methods are explored and recommendations for facilities' upgrades are formulated (D2.2, link to WP3).

Tools and methodologies will be deployed at the UCC campus and then validated on other campuses (D2.3). Collected data before and after monitoring infrastructure upgrades is compared to assess and evaluate the degree of performance improvement (D2.4).

Work package 3

The concept of systems integration aims to addresses the deficit of open, standardised systems interoperability. Systems are considered openly integrated if they share resources seamlessly without duplication and in which redundancies are deliberate rather than incidental.This work package aims to deliver demonstrable results for the integrated systems concept and achievements through industry focused use case scenarios developed at three European deployment locations. These demonstration sites are the campus of University College Cork in Ireland and the Commerzbank Sports Arena in Frankfurt, Germany.

The primary goal is to deploy and test the tools and methodologies for holistically integrated energy systems developed in work packages 4,5 & 6 and achieve successful project results. Work package 3 will be delivered in close collaboration with WP1 in order to extract lessons and develop guidelines for future planning and financing of Integrated Energy Management and Service Systems.

Work package 4

WP4 middleware

WP4 addresses the Scientific and Technological Objective STO 4 aiming for Development and Deployment of an ICT Service Platform for Energy Systems Management.

The focus of WP4 is on the development of the core platform that shall enable the integration of different ICT building subsystems including BMS/BEMS, occupancy monitoring and external context systems (e.g. weather information, power grid congestion) into a single control system.The integration methodologies and components (middleware) make use of proven standards in communication.

Based on the requirements discussion driven by the use cases and the implementation potential at the different demonstration sites, a system design for the CAMPUS-21 data monitoring and control infrastructure is provided and specified with its components and interfaces. The results coming from other work packages – the Data Warehouse Tool for Performance Data Management (WP2), the Control Software for Micro Generation and Energy Storage (WP5), and the tools for Load Balancing in Distribution Grids (WP6) – will be integrated.

Work package 5

WP5 flow diagram

Utilization of existing buildings' monitoring data and the integrated analysis of this data can support the efforts to improve energy efficiency through the optimization of buildings' operational regime. In this work package, we collaborate with industrial partners to address gaps and deficits in current control strategies and algorithms and seeking new solutions.

Novel approaches toward optimised integration of energy generation and storage systems are developed for the demonstration campuses. In-depth knowledge of energy demand and occupancy patterns is required in order to optimise the operational scenarios for different types of energy harvesting and energy storage systems.

Work package 6

WP6 block diagram

WP6 considers load balancing in buildings and local energy distribution grids, and develops tools which optimize overall energy flows with variable demands and supply. It predicts usage pattern for rooms and building zones based on information outside typical building management systems like time tables, meeting schedules, or personal agenda, complementing access control information that may already be available.

Unfortunately, neither of these information sources provides fully complete nor accurate data, we therefore combine these diverse sources to increase accuracy of our utilization forecasts.

At the same time, we also consider using more advanced time-of-use or even real-time energy pricing information to determine when to schedule certain energy intensive operations, and how to operate local energy sources and storage to minimize energy cost and emissions. In certain situations it may be preferable to pre-heat or pre-cool a building at times of cheaper energy prices, for example using a heat-pump during the night to pre-heat a meeting room that is used during the day, and to stop heating the room during the last scheduled meeting of the day. In this way the perceived service quality for the user is not affected, while energy costs (and ultimately emissions) are reduced.

Demonstrators

UCC buildings

University College Cork

University College Cork, Ireland is a third level institution with 120 educational, research and sports buildings varying in age from 1849 to 2009 spread over approximately 33 hectares. Aside from Campus Wide experimentation and demonstration, this project focusses on two very different educational buildings, the 1910 Civil and Environmental Engineering Building (CEE) and the more modern 2006 Environmental Research Institute building (ERI).

UCC operates a CHP system which generates Electricity, Steam and Hot Water for 11 buildings around the central campus. The CHP plant runs based on the demand for electrical energy on campus.
