1. Valuating the energy you have

Basics


2. Effective use of existing local resources

Basics



3. Higher life quality: more daylight, modern architecture

Basics


- good thermal insulation - good quality windows- good quality details, airtightness- mechanical ventilation with heat recovery- efficient home appliances

==> passive house concept

Basics

“As indicated in the Plan, the Commission will propose action to ensure, that in the longer term our buildings become “near zero emitting” - called also “ passive houses”.”

Heat energy demand in different climates

Results according to PHPP regional climate data


ground storage system



after 1 year of storage after 5 years of storage4373 kWh/a



Monthly ground temperature for PHPP,heat energy demand


Conclusion: With careful planning and adequate components, passive houses within the limits of 15 kWh/(m2a) are possible in Finland, too.

Elustandardi säilimine? tõus?

kui energiatõhususe kasv õnnestub hoida määra juures 3,6% juures aastas,on energiateenuste tarbimist võimalik aastaks 2050 suurenda kahekordseks,kulutades selleks samal ajal poole vähem energiat
