IBO - <strong>Environmental</strong> <strong>and</strong> Health <strong>related</strong> Criteria <strong>for</strong> Buildings<br />
7.8. TQB<br />
TQB assesses the energy per<strong>for</strong>mance of a building (during operation phase) within the main<br />
category “Energy <strong>and</strong> Water” which is weighted by 20% within the overall <strong>criteria</strong> catalogue.<br />
Operational Energy<br />
The energy section within TQB is based on indicators complementing <strong>and</strong> building on each<br />
other. Possible redundancies are adjusted by the means of reduced weighting scores.<br />
The indicators assessed are the following:<br />
C1. Energy need <strong>for</strong> building operation<br />
Option 1:<br />
C1.1. Annual heating energy need (35 points)<br />
C1.2. Annual final energy need (delivered energy) (30 points)<br />
C1.3. Airtightness of the building envelope (10 points)<br />
C1.4. Free of thermal bridges (10 points)<br />
Option 2:<br />
Optional to C1.1.-C1.4.: If the building is certifiable in accordance with the guidelines<br />
of the Passive House Institute Darmstadt, the highest score <strong>for</strong> C1.1. to C1.4. can be<br />
achieved by showing compliance with the requirements of PHPP (Passive House<br />
Planning (Design) Package) 40 .<br />
C2. Primary Energy / CO 2 -Emissions (building operation)<br />
C2.1. Annual Primary Energy Requirement (non-renewable) (65 points) or optional<br />
C2.1a Use of renewable energy sources <strong>for</strong> space heating (25 points)<br />
C2.1b Domestic hot water (solar collectors/heat pumps, insulation of buffer<br />
store, warm water connection <strong>for</strong> washing machines/dish washers) (20 points)<br />
C2.1c Photovoltaic (10 points)<br />
C2.1d Energy-efficient mechanical ventilation system (5 points)<br />
C2.1e Energy-efficient lighting (5 points)<br />
C2.2. CO 2 -Emissions (building operation) (20 points)<br />
Besides the main indicators, heating energy dem<strong>and</strong> <strong>and</strong> final energy dem<strong>and</strong> including the<br />
losses of transmission, ventilation, solar <strong>and</strong> internal gains <strong>and</strong> losses/gains of the building<br />
services, special attention is paid to thermal bridges <strong>and</strong> airtightness.<br />
Rating starts with fulfilment of the actual Building Regulation requirements (2010 level). The<br />
highest level is defined by 10 kWh/m² conditioned gross floor area a heating energy need referring to the<br />
national calculation methodology (OIB-Guideline 6 41 ). Final energy need 42 shall undercut the<br />
