Achieved harmonisation of building codes and integration of ventilation, cooling and lighting into <strong>the</strong> certificate. Also,<br />
some lessons learned were: <strong>the</strong> need to improve <strong>the</strong> quality of energy certificates, ensuring proper qualification of<br />
energy consultants, enforcing <strong>the</strong> obligation to present <strong>the</strong> energy certificate, and increasing <strong>the</strong> level of acceptance<br />
of <strong>the</strong> energy certificate by <strong>the</strong> real estate sector. In this regard, <strong>the</strong>re are substantial weaknesses which should be<br />
corrected in <strong>the</strong> course of revising <strong>the</strong> respective documents and regulations according to <strong>the</strong> requirements of <strong>the</strong><br />
EPBD Recast.<br />
Streng<strong>the</strong>ned or new requirements for insulation, ventilation and technical installations. Some tendencies after<br />
<strong>the</strong> EPBD implementation appear to be: condensing boilers are more and more being used for heating, <strong>buildings</strong><br />
tend to be better <strong>the</strong>rmally insulated, increased use of mechanical ventilation systems with heat recovery, more<br />
attention to <strong>the</strong> air tightness of <strong>the</strong> envelope (mostly in low energy <strong>buildings</strong>, performing (much) better than <strong>the</strong><br />
common average in <strong>the</strong> past) and increased interest in heat pumps.<br />
Streng<strong>the</strong>ned requirements for insulation and glazing U-values; raised national consciousness of energy saving<br />
opportunities<br />
The cantonal regulations in <strong>the</strong> field of <strong>buildings</strong> had an additional annual impact of about 3.1 PJ/a between<br />
2000 and 2007 (additional impact every year; final energy use). The expected additional annual impact after <strong>the</strong><br />
implementation of <strong>the</strong> “MuKEn 2008” is quantified at 4.2 PJ/a.<br />
The implementation of <strong>the</strong> EPBD was <strong>the</strong> first attempt ever made to regulate energy consumption in <strong>buildings</strong>.<br />
Thermal insulation requirements were introduced for <strong>the</strong> first time in 2007 along with greater importance given<br />
to efficient technical systems and solar strategies (shading). After <strong>the</strong> EPBD implementation, <strong>the</strong> following<br />
impacts and benefits were observed: improvement of <strong>the</strong> quality of information on <strong>the</strong> building products and<br />
better competition between producers and vendors in supplying materials of improved <strong>the</strong>rmal properties,<br />
integration of <strong>the</strong> importance of efficient technical systems in <strong>the</strong> energy performance of <strong>buildings</strong>, also more<br />
designers have shown interest in heat pumps and condensing boilers. Also <strong>the</strong> EPBD is expected to stimulate<br />
energy savings of 19.9 toe from <strong>the</strong> residential section and 28.5 from <strong>the</strong> non-residential sector by 2020.<br />
The performance requirements of renovated <strong>buildings</strong> have been set at <strong>the</strong> same level as for new <strong>buildings</strong>.<br />
Increased energy efficiency standards can contribute more than 220 billion CZK (energy savings, new work<br />
possibilities etc.) to <strong>the</strong> Czech State budget.<br />
Thermal performance requirements had been in place since 1977. EPBD introduced requirements for building<br />
renovations. Efficiency plays a more important role in building services, <strong>the</strong> need for better coordination among<br />
all actors has been perceived and <strong>the</strong> aim of realizing an integrated planning approach seems to have been<br />
boosted.<br />
Energy requirements in place since 1961 were extended to include o<strong>the</strong>r regulated energy as a result of <strong>the</strong> EPBD<br />
Prior to 2008, <strong>the</strong>re had been no legal requirement for insulation levels or technical systems.Depending on<br />
<strong>the</strong> EPBD implementation scenario, energy savings in <strong>buildings</strong> can be up to 5% of total energy consumption.<br />
Transposition of <strong>the</strong> EPBD has not affected investments or investment support schemes targeted at energy<br />
efficiency upgrades in <strong>the</strong> <strong>buildings</strong>.<br />
Considerably tougher requirements for building envelopes; use of renewable energy made compulsory in new<br />
<strong>buildings</strong><br />
Thermal requirements have been in place since 1976. Energy performance is now based on overall primary<br />
energy consumption.New building regulations were introduced at <strong>the</strong> beginning of 2010 which will lead to 30%<br />
efficiency improvement in heat consumption in new <strong>buildings</strong>. Revised energy efficiency parts of <strong>the</strong> building<br />
code are expected to enter into force at <strong>the</strong> beginning of 2012. This would mean a fur<strong>the</strong>r improvement of 20 %<br />
in <strong>the</strong> efficiency of heat consumption in <strong>buildings</strong>.<br />
20% improvement due to introduction of requirements for air conditioning, lighting, active solar, renewable, CHP<br />
and natural lighting. The absence or delay in implementing <strong>the</strong> inspection of boilers has reduced <strong>the</strong> quality and<br />
precision of Energy Performance Certificates in collective dwellings.<br />
Tighter energy performance requirements<br />
Revised methodology has led to tougher energy performance requirements<br />
