Climate change – challenging building
Carbon dioxide is the most significant greenhouse gas generated by human activity. The current levels of carbon dioxide in the atmosphere are higher than at any time in the past 20 million years. Fossil fuels, such as coal, oil and natural gas used in energy production and transport, are the greatest source of emissions.
Climate change is expected to present significant challenges to humanity, from desertification to rising sea levels. In the Baltic Sea region temperatures may even fall as a result of changes to the Gulf Stream(1).
With buildings accounting for 40 percent of Europe’s annual energy consumption(2), improving their energy efficiency is the key way to cut emissions. In new buildings construction, the installation of high-quality thermal insulation is the most cost effective method for reducing energy consumption(3).

Energy efficiency – the emerging trend in building
Low-energy buildings have been researched and built in Europe since the 1970's and their numbers are increasing rapidly. The past decade has seen the building of thousands of ever more sophisticated passive buildings. The EU has passed a directive that makes all new buildings nearly zero energy buildings by the end of 2020.
No new technical skills, special equipment or materials are needed to build an energy efficient building. Even passive buildings can be constructed using common construction methods. This applies to both new buildings and renovation. In old buildings the target is to upgrade the energy efficiency of each building component when it becomes due for renovation.
The PAROC® Energywise House™ Concept
- energy efficiency in building solutions
Paroc is an energy efficiency expert and leading developer and provider of energy efficient insulation solutions. PAROC Energywise house is a forward thinking, energy-efficient building concept that draws on Paroc know-how.
Our aim is to demonstrate to building authorities, designers, architects, professional builders, dealers and house owners the undisputable benefits of energy-efficient building, cosy and comfortable living, fresh and healthy indoor air, minimised heating energy costs and decreased CO2 emissions. PAROC Energywise house also provides ideas, recommendations and instructions to realise low-energy and passive buildings and offers energy optimizing solutions for renovators.
The concept consists of four energy-efficiency options: Low-Energy, Passive and Plus-Energy for new buildings and Energy Optimised solutions for renovations. However, Plus-Energy buildings are still currently rare. Energywise buildings and solutions are beneficial in many ways, including cost efficiency, comfort and positive environmental impact. A passive building is in many cases the optimal solution when considering the life cycle of a building.
