# GEORGI GEORGIEV BREAKING THE WALL OF THE COMMON SETTLEMENT PLANNING

Integrated planning method for the synergistic power supply of settlement complexes

Urban policy and regulations + technical solutions + economy + society + STOCHASTIC

The three factors, used for the systemic assignment of the energy stakeholders on the analysis level in the

respective settlement area, are:

• Type and quality: Is the respective object an energy consumer or a producer, which scale does it have?

• Amount: detailed empiric analysis of every relevant stakeholder

• Topology, as energy transport distances lead to losses in efficiency and additional costs

Developing of a planning

process for the sustainable

energy supply of settlement

complexes

based on practical

experience in indiustry

complexes, industrial areas,

settlements with a mixed

usage (work, living,

industry), as well as

residential districts

Investigation of intelligent

common energy supply on a

district level: Heating,

electricity, combined

methods and systems.

Aim = improve the energy efficiency of flats,

apartments and tenements

• Multi-occupancy properties

• Taking whole block approach

• April 2013 – March 2016

• Intelligent Energy Europe (IEE) funding

• Six partner countries

• 24 case study blocks – 240 apartments

Different contexts: EPCs

• Whole building EPCs available in

all partner countries except UK

• Individual apartment EPCs

provided in all partner countries

except Sweden and Germany

• Listed buildings can be exempt

• Quality of output

Page 11: Georgi Georgiev, 21. April 2015€¦ · Georgi Georgiev, 21. April 2015 # GEORGI GEORGIEV BREAKING THE WALL OF THE COMMON SETTLEMENT PLANNING Integrated planning method for the synergistic

Different contexts: management

• Property managers or management boards

exist in all partner countries except the UK

– Often required to have annual meetings

• Various ownership models:

– Housing co-operatives

– Homeowner association

– Fully owned by one organisation

– Fully private owned (different owners)

• Decision procedures and voting rights vary

– Majority usually required for refurbishment

Page 12: Georgi Georgiev, 21. April 2015€¦ · Georgi Georgiev, 21. April 2015 # GEORGI GEORGIEV BREAKING THE WALL OF THE COMMON SETTLEMENT PLANNING Integrated planning method for the synergistic

Scottish context

• Improvements more

likely in individual flats

than communally:

– Getting agreement and

securing finances is

difficult

• Tenements Act - further

clarity required

• Householders need to be

persuaded of the

benefits

Case Study Aachen

Roof warm loft insulation is planned for the next year, in order to reach the required energy efficiency by the national regulations. An extraordinary full owner community meeting will be scheduled for November 2014, to take decision by the owner community. I should be there.

Case Study Bonn

New gas central heating will be installed in the complex. It has been discussed also about installing a pellet heating system, the idea was mainly supported by the investors in the owner community (owners of more than one flat in the complex, who rent their flats). The reason was, that the start invest would be higher than the one for the gas heating system. About 60 % of the flats in the complex are owned by owners, who live there and own one flat each. In connection to the heating system exchange, the owners are thinking about smart heating control by individual room climate based valves. For both actions they became from our team a lot of explanations and recommendations during their last Annual Full Owner Community Meeting and the time after.

Technical Development – Intelligent Heating Automation for the Smart Home of tomorrow

Arguments pro an individual heating automation system

• Easy-to-set daily home usage schedule

• Good energy usage overview

• Strong reducement of the energy usage by heating only in the times needed

• Usage of the thermal mass of the building as an energy tank

• Indiv idual measure for the improvement of the energy efficiency of existing buildings and flats , especially for multi-occupancy houses with owner communities

• Fraunhofer IBP works on the development of self-learning smart home systems, in order to provide energy saving techniques to the society and the markets

Emerging lessons - engagement

• Time intensive!

• Challenges:

– Private rented properties

– Social relationships between owners

– Lack of interest / awareness

– Finding contact details

• Successes:

– Working with trusted, known organisations,

where formal management arrangements

exist e.g. property managers

– Resident meetings

• Maintenance works – present

challenges & opportunities

Page 43: Georgi Georgiev, 21. April 2015€¦ · Georgi Georgiev, 21. April 2015 # GEORGI GEORGIEV BREAKING THE WALL OF THE COMMON SETTLEMENT PLANNING Integrated planning method for the synergistic

EPC recommendations

• Limited impact on energy rating

• Planning restrictions

• Residents don’t want disruption of install

Finance

• Major issue

• Availability varies across Europe

• Uncertainty in funding programmes can make planning

difficult

• Maintenance funds exist in some countries – but

insufficient

Emerging lessons

Page 44: Georgi Georgiev, 21. April 2015€¦ · Georgi Georgiev, 21. April 2015 # GEORGI GEORGIEV BREAKING THE WALL OF THE COMMON SETTLEMENT PLANNING Integrated planning method for the synergistic

• Tackling flats is challenging across Europe

• We need better technical tools - EPCs are a

starting point

• Robust and flexible frameworks are needed to

secure the support of owners from project

initiation to installation

• Scotland’s EPC regime, tenure split and system

for regulating maintenance in communally owned

buildings is especially challenging

• Case studies are needed to illustrate success

stories
