Low carbon solutions for zero energy buildings


Finland is preparing to move towards near zero energy buildings due to the Energy Performance of Buildings – directive. It requires all new buildings to be near zero energy buildins (nZEB). As preparation for the directive, the goal is to modify Land Use and Building Act by the beginning of 2017 and the regulations for energy efficiency to be put into operation for all building permits starting from 2018. Construction industry, as well as citizens building new houses, are facing a major change and it has to happen fast. There is no more time to ponder the criteria of a near zero energy building.

Achieving long term climate goals is impossible without major actions in built environment. Execution of the EU directive is one action towards the goals. In order to reach the goals, practical work in creating examples and open models needs to be done. Current meters and calculators for near zero energy buildings are complex and far from user friendly. Also the effects of living life cycle are difficult to determine. Public examples and open information about performed modifications help people to react to coming changes more positively and courageously.
The aim of this project is to produce different models of energy efficiency and building solutions effect on filling the requirement of zero energy buildings and the carbon footprint. In addition to this the aim is to:

1. add SMEs awareness of low energy solutions carbon footprint
2. create opportunities for new business based on low carbon goals and
3. simplify single-family house residents ability to influence in the carbon footprint of the house

In this project, houses being built in Karjaranta 21 living area are modeled and their carbon footprint is calculated. Based on the calculations and models, requirements for these houses to reach zero energy house definition are researched. Also, the effect of these solutions to the e-value and carbon footprint of the houses are calculated. In addition to this, if near zero energy buildings are modeled, the requirements for more cost efficient solutions are researched. While performing these, the use of renewable energy (and its carbon footprint) and digital solutions in energy consumption optimization is researched. From the results of these actions, a simple and user friendly guide about solutions in the construction phase that effect the carbon footprint, is produced. In addition to this, model examples from the modeled houses will be published.

The project promotes transition to low carbon economy and knowhow of zero energy buildings in Satakunta. Modeled solutions help in every step from regional planning to living in a house. For Satakunta region, this project provides boost to new business opportunities in low carbon business.
