NZEB Buildings

Towards Nearly Zero-Energy Consumption through an Integrated Energy Management Solution.


Why is it a trending topic?

Commercial and residential buildings in Europe are overall responsible for around half of total energy consumption and 36% of CO2 emissions. Improvements in energy efficiency within the buildings sector in tandem with the increased use of renewable energy technologies constitute important policy measures needed to facilitate a reduction in energy dependency on fossil fuels and associated greenhouse gas emissions. The building sector is keen to improve its sustainability standards and also to help achieve the 20-20-20 targets set by the European Union.

Nearly Zero-Energy buildings (NZEBs) are those that have a very high performance, in which the low amount of energy required should be covered from renewable sources (produced on-site or nearby). According to the Energy Performance of Buildings Directive, by the end of 2020, all new buildings must be nearly zero energy buildings.

“In other words, NZEB for a large number of end users can be reached producing extreme low carbon energy (photovoltaic panels, biomass, solar hot water, cogeneration, district heating or cooling, etc.) with efficient demand such as Building insulation & Airtightness, passive heating, bioclimatic architecture, load’s control, etc.”


In Spacewell Energy by Dexma we help organisations so their buildings could be ready for the incoming Nearly Zero Energy era.

Integrated Energy Management Solution that allows you to get the energy balance of your building (Generation, Storage and Demand). Spacewell Energy – Dexma Detect also adds value to your Analyse account:

Renewable Energy Generation

Track details about your Renewable Energy Generation Technology (performance, production, etc.)

Energy Storage
