PAROC® Energywise House™

Paroc's Energywise house™ concept, gives advice and instructions about what you can do to reduce energy consumption when building new houses or when renovating. An energywise solution means achieving higher requirements than those stipulated in the building regulations, which is a good investment for the future. When you want to build energywise, think PAROC® Energywise house™.

 

Climate change – challenging building  

Earth

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

 Woman with drawing

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.

 Energywise House concept

8 good reasons to build energywise:

 Energywise House economy dimension     

 

Energywise buildings can bring savings of up to EUR 50 000 over 25 years - that's equal to the cost of a new car - and may achieve resale prices up to 30 % higher in comparison with standard houses.

      

Upgrading the energy efficiency of a building to a passive level requires an extra investment of only 5% -10 %, as heating systems can be downgraded or left out entirely.

 

Passive life cycle costs

    

 

 

In the Energywise design of a building the investment decision is based on total costs derived by adding up the energy costs throughout the whole life cycle of the building to the cost of construction.

In terms of lifespan cost, passive building represents optimal design.

People spend more than 80% of their time indoors and a third in their bedrooms. Thanks to careful insulation, Energywise houses are draught free and warm throughout. Efficient and controlled ventilation, an air tight building envelope and low-emission building materials mean that indoor air is always clean and fresh.

As with any building, an Energywise house can be designed to suit your style and taste. Your imagination is the only limit when creating stylish and cosy interiors.

    The repair and maintenance work in a passive building is reduced because no separate heating system is needed. Moreover, the house needs fewer technical appliances, which means less energy is used.
 Energywise House energy dimension    

It is estimated that energy consumed during the entire life cycle of a building makes up to 80% - 90% of its environmental burden.

Energywise buildings are significantly more environmentally friendly. The energy savings offered highlight the key role of owners, designers and builders in creating a better future for the generations to come.

The energy efficiency sector is growing all the time, generating new business activity and job prospects. New innovations will emerge, energy efficiency specialists from designers to builders will be needed and the entire construction industry will develop to a new level.
