Buildings are one of the most resource demanding sectors, generating approximately one-third of all greenhouse gas emissions. To reduce the emission footprint of the building sector in a cost-effective and sustainable way, the IEA has released a guide that highlights the benefits of energy planning for public communities of different scales such as small groups of buildings, campuses, cities, regions or even countries.
The IEA’s new guide has been developed by an international team under IEA’s Energy in Building Communities programme (Annex 73) and it provides a better understanding of the energy master planning process through cases and best practices from around the world, including Denmark.
Anders Dyrelund, Market Manager, has represented Ramboll in developing the guideline, bringing valuable experience from Denmark. He says:
“We are in the middle of a green energy transition and the question of how to do it in a smart and most importantly, affordable way is crucial. With more and more people living in cities, it is important for authorities and city planners to address this question and benefit from smart sector integration in cities. This is exactly where this guide comes in handy, and I am happy that Ramboll was able to contribute with our knowledge from Denmark”.
Denmark has over forty years of experience in city-level energy supply planning where smart sector coupling between public transport, electricity, district heating and cooling, gas, waste, and buildings has been one cost-effective way of accelerating low-carbon energy production. Opposed to the traditional way of addressing the energy system based on individual facilities, smart sector coupling is done by adopting a holistic view of how energy is produced, distributed, consumed, and stored across the energy carriers.
A great example of using smart sector coupling is the urban development district at the Kastrup Metro station in Taarnby Municipality, a suburb in Greater Copenhagen and the first to combine district heating with district cooling and wastewater to produce low-carbon energy for the growing community and business sector in the area. This project as well as the Greater Copenhagen District Heating system, are highlighted in IEA’s guideline as cases underlining the importance of energy planning.
