Make decarbonisation of existing buildings a reliable, attractive investment

Solutions and technologies for the uptake of deep energy renovation processes

What is StepUP?

Deep renovation is a key action to drastically reduce energy demand and achieve the EU vision of a decarbonised building stock by 2050. However, only 1% of European buildings are being renovated yearly and shallow retrofits persist with low impact on energy consumption.

The StepUP project has developed new technologies and solutions to make building renovation more attractive and affordable.

To achieve this, StepUP used continuous feedback loops and promoted an iterative deep energy renovation approach, based on data insights, which minimised performance gaps, reduced investment risks, minimised disruption and positively impacted on energy costs, Indoor Environmental Quality (IEQ) and comfort.

Flexible cooling & heating solution deployed in two sites for greater energy efficiency

One of the biggest challenges of HVAC systems is that heating or cooling energy needs to be generated on demand when the need occurs. HeatTank Thermal Battery system, developed by HeatVentors, is a solution to produce heating or cooling energy when it is the most efficient, when it is the cheapest, or when waste heat …
