IEA DSM Task 17 - Extension: Integration of Demand Side Management, Distributed Generation, Renewable Energy Sources and Energy Storages (working period 2013 - 2016)

The aim was to exchange experiences and developments in the field of integrating renewables with the help of DSM in residential and commercial buildings. Technologies like PV systems, electric vehicles, electric storages, heat pumps, micro-CHP in combination with energy management systems (via gateways), and implementing dynamic tariffs using smart meters offer huge potential to increase energy efficiency. Phase 3 of this Task addressed the current role and potential of flexible buildings and their related implied changes and impacts on the grid and markets. The scalability and applicability of successful projects with respect to specific regional differences and requirements was also explored.

IEA DSM Task 17: Integration of Demand Side Management, Distributed Generation, Renewable Energy Sources and Energy Storages

The main objective of the proposed Task is to study how to achieve the optimal integration of distributed generation, energy storages and flexible demand, and thus increase the value of distributed generation and demand response and decrease problems caused by intermittent distributed generation (mainly based on RES) in the physical electricity systems and at the electricity market. The Task deals with distributed energy resources both at local (distribution network and customer) level and at transmission system level where large wind farms are connected.

IEA DSM Task 24: Behaviour Change in DSM – Helping the Behaviour Changers (Working period 2015-2017)

More than 20% of the use of energy for small consumers can be saved by changed behaviours. Past efforts to tap these potentials through DSM-interventions are not effective. The Task 24 dealt with the most important actors groups as well as tools, which support the behaviour changers in their daily work. In addition, an assessment method for DSM-interventions in the frame of the Austrian law on energy efficiency was elaborated.

IEA DSM Task 25 – Business Models for a more effective market uptake of DSM energy services

This task aims at the identification and development of effective business models for energy services, which lead to a sustainable growth of energy efficiency services. Therefore the various national framework conditions and contexts have been analysed, that are necessary for a successful development of such business models. Examples for start-ups and entrepreneurs have been discussed, their challenges and deficits as well as success factors in terms of capabilities/skills identified and out of these findings a web based analysis tool been developed.

IEA Demand Side Management Energy Efficiency (DSM TCP)

Demand Side Management (DSM) refers to the implementation of energy efficiency improvements and service management measures on the side of end users for optimising energy systems overall. This IEA-research programme pushes development of suitable technologies, applications and methods for end users and thus facilitates their preferential adoption in all political decisions on energy policy.

IEA EBC Annex 55: Reliability of Energy Efficient Building Retrofitting - Probability Assessment of Performance & Cost (RAP-RETRO)

The scope of the project is to develop and provide decision support data and tools for energy retrofitting measures. The tools will be based on probabilistic methodologies for prediction of energy use, life cycle cost and functional performance. The impact of uncertainty on the performance and costs will be considered. Methods based on probability give powerful tools that can provide us with reliable ranges for the outcome.

IEA EBC Annex 57: Evaluation of the design-specific CO2 emissions and the gray energy

The IEA-EBC Annex 57 evaluated methods of construction-related embodied environmental impacts and embodied energy and related international best practice projects and their approaches. Based on these findings, methodological guidelines as well as measures for their application at the international level and for the planning of buildings - with lower embodied energy and embodied greenhouse gas emissions - were derived.

IEA EBC Annex 62: Ventilative Cooling

The main goal of the Annex 62 is to make ventilative cooling an attractive and energy efficient cooling solution to avoid overheating in buildings. Ventilation is already present in buildings through mechanical and/or natural systems and it can remove excess heat gains as well as increase air velocities to widen the thermal comfort range. The results from the Annex facilitate better possibilities for both design purposes and for energy performance calculation.

IEA EBC Annex 64: Optimised Performance of Energy Supply Systems with Exergy Principles

To reduce CO2 emissions in cities, an overall understanding of energy conversion processes is necessary, which also takes temperature levels into account. This is particularly important when alternative heat sources such as waste heat, ambient heat, solar and geothermal energy are to be used, as these often have a low temperature level, i.e. a low exergy content. Accordingly, urban energy systems are analysed and optimised within the framework of the IEA EBC Annex 64 with the help of the exergy approach.
