Webinar 6. Operational optimisation of building energy performance based on activities during EPC generation

The new EPBD recast aims to increase the rate of renovations of energy-inefficient buildings and improve information on energy performance. Member States shall ensure that energy performance certificates (EPCs) are affordable and issued by independent experts following an on-site visit. 

 

In the context of the TIMEPAC project, on-site visit is essential element of the EPC generation process and must be properly planned. During the on-site visit, the certifier should visually inspect the condition of the equipment, systems, and living/working spaces. During this webinar, we will explore how to combine the on-site visit with re-commissioning activities. Our goal is to empower participants with the necessary knowledge and skills to provide cost-effective optimization advice based on activities during EPC generation. Re-commissioning (Re-Co) is the expression used to describe an energy-system operation-optimization service in existing buildings. It focuses on improving the overall performance of a building by investigating and improving how systems operate together. It consists of a rapid energy audit of the buildings, focused on a check and re-set of the energy system’s operating parameters. Even though they might give rise to some additional costs, Re-Co services can be carried out successfully and be a cost-effective part of the EPC-generation process because they will generate additional benefits for the owners and building users. The webinar will also provide insights into the monitoring and targeting techniques and comparing the existing with the expected performance.

Re-Commissioning: Creating Awareness and Common Understanding

EN

Re-Co is the process of re-optimizing existing buildings that have already been commissioned. It aims to ensure that building equipment and systems operate at their best to meet the current needs of occupants. This session aims to raise awareness and foster a common understanding of Re-Co activities. When conducted systematically and comprehensively, Re-Co is a powerful tool for evaluating current or past energy performance and management practices. Additionally, this session will provide efficient tips on identifying typical mistakes that influence energy performance, such as incomplete equipment installation or inappropriate settings of control devices.

Distinguishing Re-Co from Energy Audits and Retrofits

EN

Re-Co activities can be regarded as part of ab energy audit, focusing primarily on identifying low-cost energy efficiency measures which can be implemented during the audit’s execution. The inspection of the on-site metering system establishes a direct link between Re-Co and energy auditing. On-site metering holds significance as it furnishes firsthand information on energy performance. This session will provide practical and effective tips on inspecting existing metering infrastructure, devising a simple and reliable metering plan, and facilitating target setting.

Re-Co in the Building Life Cycle

EN

This session will provide a variety of examples of Re-Co measures applicable throughout the building’s life cycle. Participants will also receive insights into of the Re-Co report. The content of this report must always be tailored to the complexity of the systems inspected and evaluated. The primary objective of the final report is to persuade the building owner to initiate the implementation of proposed performance improvement measures and projects, demonstrating that these measures can compete effectively with other investment opportunities in terms of their own return on investment.

Re-Co and EPC

EN

This session will outline how the EPC generation process can be integrated with Re-Co activities. In this context, these activities are regarded as components of a quality-oriented process aimed at achieving, verifying, and documenting whether a building’s systems and equipment performance still aligns with the originally defined objectives and criteria. Participants will learn how to utilize the data collection process to identify performance improvement opportunities from the collected and calculated data. Additionally, participants will learn how to use the Re-Co checklist to ensure that critical performance opportunities are effectively identified.

Planning Re-Co activities

EN

For any activity related to energy performance assessment, planning and preparation are crucial phases. The planning activities within the framework of the Re-Co should be documented in the form of a work plan, which should be shared with the owner/users before visiting the building to carry out the intended work. The work plan must outline which part of the building is to be visited, the purpose of the visit, the documentation and data required, and the necessary personnel to be involved. This session will present the main elements of proper planning of site visits.

Re-Co and BACS

EN

The term ‘Building Automation and Control System’ (BACS) refers to centralized systems that monitor, control, and record the functions of various building systems. Building facilities monitored and controlled by a reliable BACS tend to maintain the building environment more efficiently, reducing the building’s environmental impact and energy costs. This session will outline how to assess existing on-site sensors, metering and control equipment within the framework of Re-Co. Participants will learn how to identify performance improvement opportunities based on the settings of the existing control systems.

Re-Co and HVAC

EN

This session will describe a systematic, quality-oriented process aimed at enhancing the performance and sustainability of existing HVAC systems. Participants will be guided through a step-by-step process to maximize facility effectiveness while minimizing investment and ensuring long-term benefits. Common best practices in HVAC optimization will also be presented. In addition, the session will cover the content of the resulting report, including suggestions and proposals, cost estimates, evaluation of the amortization period, and estimates of savings in terms of both consumption and cost.

Re-Co and electrical lighting

EN

Lighting systems play a crucial role in creating a comfortable working environment. However, over time, all lighting systems become less efficient. One of the main goals of re-commissioning lighting systems is to improve the building energy efficiency. This can be achieved by identifying and addressing issues such as over-lighting, optimizing lighting control, and the use of outdated or inefficient lighting technologies. This session will provide an overview of the main steps involved in assessing existing lighting systems, identifying opportunities for improvement, developing a plan of action, implementing changes, monitoring and evaluating performance, conducting regular maintenance, and creating documentation.
