Scope of presentation :Part 1:•Energy efficiency in the building sector – current Polish trends•New regulations in Poland (2008) of EPBD and energy efficiency EC Directives implementation,•First certified and passive buildings – example data and parameters.Part 2:•Energy saving and low emission technologies in practice:- Rzeszow Province examples,- First certified and passive buildings.

Building sector - Some statistical data

Heat generation costs of heating systems in Poland (2007)

Time-shedule of introducing EPBD certificates in Poland

Starting point – 2008:

• First certificate: May 12 – 2008: Primary School No.6 in Zamosc

• Second: 28 May 2008 Center for Blind Children, Laski

Buildings and Certificate for SP No.6 in Zamosc

New ordinances and legislation acts - 2008

Regulations:•7th May 2008 - Ordinance of the Ministry of Council on the auction procedure for new investments in energy sector and energy saving initiatives (new rules of an auction procedure and its documentation).

• 28th May 2008 - Ordinance of the Ministry of Agriculture on the methods of recording the amount of harvesting plants for energy production (mass and volume measuring).

•1th July 2008 - Ordinance of the Ministry of Council on the conditioning CO2 emission limits between 2008-2012 (code E1-E3, F1-F2, M1-M3, O1-O2 depending on industry branch and annual production). An attached Annex includes 838 companies in Poland.

•14th August 2008 - Ordinance of the Ministry of Council on an obligatory submission for extinguishing testimony of an origin for the amount of renewable energy production (biomass /biofuels, CHP/hybrid units – all in percentage units up to 2017 year).

New ordinances and legislation acts - 2008

• 6th November – Ordinance of Ministry of the Infrastructure on the methodology of calculation the energy consumption characteristics of dwellings and premises. The main part of this ordinance is quoted to „Certificate”documentation.

• 6th November 2008 - Ordinance of the Ministry of Infrastructure on the specification the scope and form of construction design (HVAC system analysis, study of the renewable energy use for building area > 1000 m2 ).

• 6th November – Ordinance of Ministry of the Infrastructure on the technical conditions for buildings and their localization.

Ordinance of the Minister of Economy on Electricity PurchaseObligation: The Ordinance stipulates that power utilities had to purchase 2.4% of the electricity from renewable sources in 2001. This percentage will be gradually increased up to 7.5% in 2010.

According to the Article 1/1 of the Oordinance energy utilities are obliged to buy electricity and heat from unconventional or renewable sources connected to the common grid regardless of the installed particularly electricity and heat from:? hydro plants,? wind plants,? biogas , especially obtain from :- waste water treatment plants,- municipal waste disposal sites,- agricultural waste processing,? biomass,? biofuels,? solar photovoltaic cell,? solar heat generation collectors,? geothermal heat.

• Not completed and well prepared procedures of building certification (methodology based on 13790EU Standard /2006 year).

• Not actual data base on construction material properties and reference technologies.

• Not well developed training system (no precise conditions for future survey expert qualifications, lack of final exam evaluation methods and not easy access to standards).

• No local expert centers and selected software for test evaluation. • Lack of formal cancellation procedures (Ministry <-> customer or

developer).• Building certificate based only on the design conditions (statistical

data – not real occupancy data during exploitation).

Some questions of implementationthe actual EPBD rules in Polish construction sector

Electricity production and consumption in Poland

CHP and thermal power plants - 53,0%

local HOB - coal and coke - 17,4%

local HOB - oil and gas - 3,0%

electricity - 0,7%

coal stoves - 15,9%

Municipal Waste-water Treatment Plant

Cogenerative Production of Heat and Electric Energy by the system supplied with biogas from a solid wastes (Waste-water Treatment Plant)

• The new CHP system consists of two modules MDE (IC gas engines). • Electrical power of a single module is 345 kW and heating power 531 kW. • Biogas consumption of the single module is 140 m3/h. • The heat production by the new system in 2004 was 16.108 GJ, and the

electric energy production in 2004 was 3319 MWh.• The produced heat power entirely covers the heating needs of the waste-

water treatment plant and the produced electric power covers the electric needs in 39%.

• The ecological effect as a reduction of greenhouse gas (CO2) emission were also obtained.
