Topic of the Month (January 2024)
Each month a relevant topic and several sub-topics are covered in detail. For the Topic of the Month, content following a common thread is developed by BUILD UP Editorial Board in collaboration with the Board of Ambassadors and other relevant experts in the field. This includes producing articles, case studies, webinars and more, all in line with the specific topic selected. Relevant events are also identified and highlighted.
Topics of the Month are announced at the end of the previous month in our website and newsletter. Please write us if you wish to know more about our upcoming topics of the month.

The REHOUSE project is advancing integrated solutions for energy-efficient renovation of existing buildings, currently being tested across four demonstration sites in Europe. Its technologies include modular façades, intelligent windows, and multisource heat pumps to enhance real energy performance.

Solid-state cooling technologies are emerging as a sustainable alternative to reduce emissions and energy consumption in buildings, addressing the rising demand for climate control and the urgent need to decarbonise the global building stock.


Ecoconstrucción celebró un webinar en el que líderes del sector revelaron estrategias clave para transformar edificios obsoletos en referentes de sostenibilidad.

Europe is facing challenges in replacing outdated building technologies, which hinder the decarbonisation of the construction sector. The project META BUILD is leveraging advanced technologies to optimise energy efficiency, enhance smart building integration, and support the EU’s climate neutrality goals.

In the context of the EU27 building stock, characterised by high energy demand for space heating, lowering operating temperatures in thermal systems emerges as a key strategy to enhance the seasonal efficiency of heat pumps.

The European Commission has issued new guidance to end financial incentives for stand-alone fossil fuel boilers by 2025. This move aligns with the EU’s broader climate goals, aiming to accelerate the shift towards cleaner heating solutions.

Despite efforts to improve energy efficiency, new-build homes in the UK are facing unexpectedly high energy costs. Poor construction standards and outdated building practices have led to increased energy consumption, raising concerns about the effectiveness of current regulations.

Expertos y autoridades se reúnen en Madrid para trazar la hoja de ruta hacia la descarbonización del sector de la edificación. Tecnología, eficiencia y electrificación se consolidan como pilares clave para transformar los edificios en agentes activos de sostenibilidad urbana.

From 10 to 12 June 2025, Brussels will become the epicentre of Europe’s energy transition as it hosts the European Sustainable Energy Week (EUSEW)—the EU’s flagship event on renewable energy and energy efficiency. To help you make the most of it, BUILD UP has selected the most relevant and insightful sessions focused on energy efficiency in buildings.
