1 Energy consciousness in the Long-term Urban Development Plan and in the Mid-term Strategy for Development of Budapest 1st April, 2014 Zsombor Tatai landscape architect Budapest Urban Planning Ltd.

2 PLANNING SYSTEM Planning system in Budapest REGIONAL DEVELOPMENT SPATIAL PLANNING SECTORAL PROGRAMS URBAN DEVELOPMENT URBAN PLANNING Long-term Urban Development Plan Mid-term Strategy for Development Urban structure plan (+ regulation) Zoning plans, local regulations for 23 districts

3 Long-term Urban Development Plan

4 Objective 6: Climate protection Actions: and energy consciousness 6.1 Reducing urban heat islands 6.2 Energy consciousness and low-carbon buildings 6.3 Renewable energy, waste-to-energy, wastewater treatment & energy production 6.4 Smart grid and smart metering 6.5 Development of district heating (recovery and extension) 6.6 Integrating cooling solutions into district heating 6.9 Improving the conditions of pedestrian traffic; developing the infrastructure of bicycle traffic 6.10 Developing public transport, promoting environmentfriendly vehicle (carpooling, carsharing) 6.11 Increasing public awareness

5 6.1 Reducing urban heat islands Heat map of Budapest: Almost 7 C difference in a hot summer day Circulaton caused by the heat island Poor ventilation and air quality in the centre

6 6.1 REDUCING URBAN HEAT ISLANDS Increasing the intensity of the vegetation infrared satellite image Vegetation coverage in 2010 calculated with NDVI (Normalized Difference Vegetation Index) Source: Corvinus University of Budapest, Faculty of Landscape Architecture

7 6.1 REDUCING URBAN HEAT ISLANDS Zoning codes URBAN STRUCTURE PLAN Regulation of green area ratio Avarage vegetation coverage in landuse unit Example: Housing estate (code: Ln-T) Avarage vegetation coverage: 37,1 % Green area ratio: National Law: minimum 10 % Structure Plan: minimum 50 %

8 Limiting green-field investment - promoting brown-fields - URBAN STRUCTURE PLAN UNUSED AREAS partly built-in areas Σ 225 hectars built-in areas Σ hectars AREA WITH SIGNIFICANT CAPACITY Σ hektár NO NEED FOR NEW GREEN-FIELD INVESTMENT

9 URBAN STRUCTURE PLAN Promoting brown-fields Functional and structural change of the brown-fields Establishing management for the investment Utilization of the existing infrastructure Temporary functions: recreation, energy forest

10 6.1 REDUCING URBAN HEAT ISLANDS URBAN STRUCTURE PLAN Temporary utilization: recreational park next to the West Railway Station Abandonded railways Plans for government quarters park with public participation

11 6.1 REDUCING URBAN HEAT ISLANDS LOCAL REGULATIONS Other principles Freestanding and low building in the ventilation corridors Green roofs and walls increase surface reflectivity (high albedo) more water surfaces on public places for evapotranspiration Millenráris project: demolition of an old building, creating new park for better ventilation

12 6.2 Energy consciousness and opportunity for significant energy savings in buildings Not enough data about the different type of building (for energy survey) necessary data: geometry of the building location funtion age structure heating mode energy consumption etc low-carbon buildings: low-carbon buildings Life Cycle Assessment (LCA)

13 6.3 Renewable energy, waste-to-energy, wastewater treatment & energy production Thermal water heating system was established in 2012 in the Budapest Zoo (futher information during the site visit) Communal waste to energy plant (futher information during the site visit) Electric energy from wastewater sludge: South-Pest Wastewater Treatment Plant: The produced electric energy covers 90% of the plants electric needs and 100% of its thermal needs.

14 6.3 Renewable energy, waste-to-energy, wastewater treatment & energy production Energy Park in District 10 - project idea Clay mine and brickfactory landfill site (Mixed municipal and inert waste) the waste not enough compact for buildings Proposal: mixed function environmental education recreational park Biogas utilization from the waste (profitable for 15 years) biodegrable green waste utilization Energy forest Solar park

15 6.10 Developing public transport, promoting environment-friendly vehicle (carpooling, carsharing) Decreasing road traffic caused by energy prices: % Energy consumption: 24 % Developing public transport: the New (M4) Line tarted condition: congestion charge (2016?) Secondary energy sources Energy consumption in Budapest MWh % electricity ,8% district heating ,8% natural gas ,9% petrol ,0% diesel oil ,8% coal ,16% other ,45%

16 6.9 Improving the conditions of pedestrian traffic; developing the infrastructure of bicycle traffic Public bicycle system the so-called Bubi, is scheduled to start during 75 docking stations 1100 bicycles Developing the infrastructure of bicycle traffic

18 Objective 9: Efficient urban structure compact city urban sprawl and automobile dependency city of short distances for efficient public transport system multi-centered structure mixed use
