21 06 2018 – Събитие от програмата на ЕП на България – Национална конференция по пътя на почти нулево енергийни сгради

Юни 2018:

Днес /21.06.2018/ на конференцията, от официалната програма на европредседателството на България в Бургас  –  ,,По пътя на почти нулево енергийни сгради ,,  –  презентирахме проекта в който участваме ,,A-ZEB,, и конкретно част от него, касаеща възможността от оптимизация на разходите при пасивни сгради.

The Passive House standard

The Passive House standard is the world’s highest and fastest growing energy efficiency standard that achieves a reduction in energy consumption up to 90%. There are now more than 30,000 passive buildings around the world, many of which have been built since 2000. Passive house is a super-isolated, almost hermetic building. The heating is done by the passive accumulation of energy from the sun, the electrical equipment and also by the energy of the people living in it. The remaining heat is provided by an extremely small heat source. Passive building thermostats are limited to a minimum to reduce heat loss.

Avoiding heat overheating through the orientation of the house and high-quality triple-glazed windows, help to reduce the need for additional cooling, which is often unnecessary. The passive house has a recovery system with a recuperator for energy utilization and recovery, balanced and constant supply of fresh air. The result is an impressive overall system that not only saves up to 90% of heating costs but also provides superb air quality.

Characteristics that are mandatory for the Passive House standard:

  • Annual energy demand for heating and ventilation ≤ 15 kWh / sq.m / per year
  • Annual consumption for all needs of the building ≤ 120 kWh / sq. m / per year
  • Building air impermeability ≤ 0.6 ACH @ 50 pascal load measured in a Blower-door test.  

Additional Climate Requirements:

  • Windows with U – values ​​- ≤ 0.8 W / m2 / K
  • Ventilation system with energy utilization and efficiency ≤ 75% and with low electrical consumption of 0.45 Wh / cubic meter
  • Construction without thermal bridges ≤ 0.01 W / mK

A-ZEB project progress report: Set of cost-effective NZEBs

April 2018:

Set of solutions for cost effective NZEB’s

AZEB aims to combine the knowledge and experiences of stakeholders and existing case studies into a set of solutions for the development of cost effective new NZEB’s. This set of solutions will form the basis for the AZEB methodology, that will give guidance to specific target groups in the market to create affordable (nearly) zero energy buildings. These target groups are decision makers and experts, who can use the methodology to make cost optimal decisions, give cost optimal advice and cost optimally implement the decisions made.

Work on the A-ZEB research project in progress 2

Our work on the A-ZEB research project aiming to find ways for a cheaper construction of nearly zero-energy buildings is in progress.

Representatives of 8 organizations from 6 European countries

exchange experience and seek ways through best practices and personal research, to develop an integrated methodology for cost effective reduction of such projects. In February 2018, the first part of the project was completed, especially the conditions of construction of near zero-energy buildings in these six countries.

During the next weeks, we will present the results of this phase, and today we are focusing on the integration of renewable energy sources.

8 different sources have been researched and described which, unlike Bulgaria, have been utilized and used in other countries. An example of this is biomass energy.
