International cooperations

The International Passive House Association (iPHA) and the Passive House Institute are often involved in collaborative research and dissemination projects e.g. co-funded within programmes of the European Union. Below you can find an overview of selected ongoing and completed projects with a brief description and links to further reading.

REN+HOMES - a new method for positive buildings

As the urgency to combat climate change intensifies, REN+HOMES takes the lead in developing a universal methodology for positive energy homes and residential districts. This approach addresses the crucial role that buildings play in energy consumption and carbon emissions. Due to the significant impact of buildings on emissions, there is an increasing focus on positive energy buildings (PEBs). REN+HOMES aims to contribute to a sustainable transition by not only reducing carbon emissions but also addressing resource scarcity and energy poverty. In this respect, stakeholders are involved through education and participation programmes. Our goal is to establish a universal approach for developing positive energy homes and residential districts. This facilitates the transition to climate-neutral and energy-positive residential buildings.

Articles published on Passipedia in context of the Ren+Homes project will be included here as they beome available. General topics covered by Passive House institute as part of the Ren+Homes project are:

outPHit - Deep retrofits made faster, cheaper and more reliable

outPHit - Deep retrofits made faster, cheaper and more reliable pairs such approaches with the rigour of Passive House principles to make deep retrofits cost-effective, faster and more reliable. On the basis of case studies across Europe and in collaboration with a wide variety of stakesholders, outPHit is addressing barries to the uptake of high quality deep retrofits while facilitating the development of high performance renovation systems, tools for decision making and quality assurance safeguards. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 957175.

SINFONIA - Low Carbon Cities for Better Living

The SINFONIA project is a five-year initiative to deploy large-scale, integrated and scalable energy solutions in mid-sized European cities. At the heart of the initiative is a unique cooperation between the cities of Bolzano and Innsbruck, working hand in hand to achieve 40 to 50% primary energy savings and increase the share of renewables by 20% in two pioneer districts. This will be done through an integrated set of measures combining the retrofitting of more than 100,000m² of living surface, optimisation of the electricity grid, and solutions for district heating and cooling. Co-funded by the 7th Framework Programme of the European Union.

Here you can find links to articles describing the deliverables of the SINFONIA project and how they relate to Passive House and highly energy efficient cities.

3EnCult - Efficient energy for EU cultural heritage

The project 3EnCult bridges the gap between conservation of historic buildings and climate protection, which is not an antagonism at all: historic buildings will only survive if maintained as living space. Energy efficient retrofit is useful for structural protection as well as for comfort reasons - comfort for users and “comfort” for heritage collections. 3EnCult will demonstrate the feasibility of “Factor 4” to “Factor 10” reduction in energy demand, depending on the case and the heritage value. Project duration: 2010 - 2014. Co-funded by the 7th Framework Programme of the European Union.

EuroPHit - Retrofitting for the energy revolution, one step at a time

With the EnerPHit Standard as the goal and Passive House principles as the basis, EuroPHit applies knowledge on deep energy retrofits to the oft-overlooked yet critical area of step-by-step refurbishments. EuroPHit aims to significantly increase the quality and energy efficiency of perhaps the most common type of refurbishment: retrofits conducted gradually, over a period of years. Project duration: 2013-2016. Co-funded by the Intelligent Energy Europe Programme of the European Union.
