The building sector accounts for about 30% of the global final energy consumption. Most of the consumed energy originates from fossil fuels. The operation of buildings is known to suffer from various deficiencies, degrading their energy performance. An untapped potential lies, therefore, in the optimization of building operation to significantly reduce CO2 emissions and to increase the cost effectiveness and user comfort. Over the past 40 years, extensive research has been carried out to investigate and develop methods for building performance optimization based on measured data from building services, such as heating, ventilation, air conditioning, and lighting systems. The ongoing digitalization trend in the building sector offers the opportunity to easily access large amounts of high-quality measurement data and semantic building information as digital descriptions. This facilitates the development and implementation of automated routines for the continuous supervision and optimization of building operation, including reliable fault detection and diagnosis and model-predictive control.
The Nimbus Centre at Cork Institute of Technology is delighted to have been announced as a finalist in the Sustainable Energy Authority of Ireland’s (SEAI) Energy Awards which encourage and reward excellence in energy management.
32 organisations across nine categories have made it through to the gala Awards ceremony on 25 October where winners will be named.
The announcement is a recognition of the work and effort Cork Institute of Technology has put in and underlines our commitment to a sustainable model for the benefit of our environment and our community.
Working as part of an EU H2020 project known as TOPAs (Tools for Continuous Building Performance Auditing, grant agreement No 676760) the Nimbus research team developed a context driven framework and tool which provides an integrated view of relevant performance metrics at all levels from device, zone, building and blocks of buildings supporting users with the highest knowledge empowerment to ensure sustained energy efficiency gains.
CIT have carried out significant work by:

Many stakeholders, from government officials to contractors on building sites, will be asking what are the main changes and how will they affect me ? To answer these questions, the European Alliance of Companies for Energy Efficiency in Buildings (EuroACE) has written a Guidance Note on the topic.
Key changes relate to, among others, the introduction of new voluntary tools like building renovation passports, a smart readiness indicator, reinforced inspection regimes for technical building systems and the linking of targeted or achieved improved performance to financing instruments.
Follow the links below for the full article published on 'Buildup', and for the Guidance Note available for download from the EuroACE website.
The recast Energy Performance of Buildings Directive (EPBD) was partly designed to meet the 40% indicative target for energy efficiency improvements under the Clean Energy for Europe package. One of the main provisions of in the revised EPBD, affecting TOPAs, is the introduction of a 'smartness indicator' that assesses the technological capability of buildings in ability to adapt to occupants’ needs, readiness to facilitate maintenance and efficient operation and ability to react within a smart grid. A 'Smart Readiness Indicator' (SRI) gives recognition for smarter building technologies and functionalities which enhance the energy efficiency and other pertinent performance characteristics of the building stock. It will be an incentive for the integration of cutting edge ICT-based solutions for energy efficiency into buildings, which can assist in creating more healthy and comfortable buildings with a lower energy use and carbon impact, and facilitate the integration of renewable energy systems.
The consortium believes that this is an important advancement in the certification of buildings that will improve energy efficiency and functionality of buildings in smart grids and smart cities through improving control and providing opportunities for the management of energy use in buildings in a co-ordinated manner. Based on the research performed in the TOPAs project, the Consortium has provided input into the development of the SRI. Most of the suggestions are around the role of monitoring and control in improving efficiency and for flexibility to allow consideration and recognition of emerging services such as fault detection and diagnosis and model predictive control.
Existing building energy standards in the United Nations Economic Commission for Europe (UNECE) region vary from voluntary guidelines to mandatory requirements, which may apply to one or many building types. Their development is typically a complex decision-making process that can involve any combination of participants. Building energy standards are difficult to classify and the standards that are stringent for one country may be ineffective in another country, depending on climate conditions, occupant behavior, existing building stock, and construction practices.
In response to this challenge and to strengthen understanding about the status of deployment and implementation of energy efficiency standards in buildings in the UNECE region, Committee on Housing and Land Management (CHLM) and Committee on Sustainable Energy (CSE) made a decision to develop a study on “Mapping of existing energy efficiency standards and technologies in buildings in the UNECE region” with the objective to identify which energy efficiency standards in buildings the UNECE Member States are using. The objective of this study is also to evaluate the most effective policies and highlight the best practices to help nations learn from one another and achieve greater savings. This report presents the results of this study and takes a look at the building energy standards in the UNECE region to determine which countries are embracing energy efficiency through highly effective building energy codes.
There are strong policy drivers for the promotion of energy efficiency in buildings. In the literature, Model Predictive Control (MPC) is seen as a promising solution to deal with the energy management problem in buildings. Model identification is the primary task involved in the design of MPC control and defining the good level of complexity for the thermal dynamic model is a critical question. This presentation focuses on the development of reliable models that can be used to support the deployment of (Distributive (Di)) MPC application.
The presentation attached below was given by CEA & CIT at the Sustainable Places 2018 event on June 28th, in Aix-les-Bains, France.
As part of Sustainable Places 2018 (www.sustainableplaces.eu/) the TOPAs Project (www.TOPAs-eeb.Eu) will host a workshop: Tools & services for upscaling energy management from buildings to blocks of buildings highlighting the key achievement of the project in addressing post-occupancy performance management for blocks of buildings through an open IoT platform that provides a reference architecture for the integration of blocks of buildings to address scalability of energy management, eliminate vertical data silos and enable holistic management and verification of energy usage.
In partnership with complimentary projects in the energy efficiency building domain, TOPAs in conjunction with MOEEBIUS (http://www.moeebius.eu/), HIT2GAP (www.hit2gap.eu/), E2District (http://e2district.eu/), INSITER (www.insiter-project.eu/en) and HOLISDER (http://holisder.eu/) projects will present a joint workshop:Reducing the performance gap between predicted and actual energy performances at the level of buildings and blocks of buildings that explores the cross cutting challenges related to ,Data Management, Citizen (occupant) engagement, Replicability & Business Modelling, Upscaling Energy Management, Building Performance Optimisation & Gap Reduction.

The energy consumption of buildings lies often far above the performance objectives of the design phase. This is due to several factors, among others serious deficits in the energy operation of building services. TOPAs adopts the principle of continuous performance auditing by not only considering energy use but also knowledge and understanding of the buildings use and their climatic state. Thus it provides a holistic performance auditing process through supporting tools and methodologies that try to minimise the gap between predicted and actual energy use. TOPAs offers an open BMS IoT driven framework. This framework is composed of core services to connect to any BMS and aggregate all the information in an open platform. Add-on services are also available to improve the understanding of buildings and reduce further the gap.
