Euroheat & Power conference Brussels, Belg. – June 5, 2008

Heating & Cooling "la Genève internationale" :

The Genève - Lac - Nations (GLN) Project

Alexis Mayer – Geneva State Energy Office

Euroheat & Power conference The Geneva Concerto Project Brussels, 05.06.08

Project's context• Concerto : EC project – DG

TREN

– FP6 (FP7 = 3rd round) Sustainable energetic solutions for

urban areas (RES, RUE)

– 46 Communities (18 projects)

• Tetraener (2005-2010)

– Development of admin. & resid. district

– Geneva (CH) GLN + SanSebastian/Bilbao (Sp.) + Franckfort (De.)

• Geneva Energy policy– "2 000 W" Society

Global Energy conception Energy Master Plan (legal-financial measures, energy

planning…)

– Energy planning : strategic systematic & opportunist approach


Geneva's project - Overview

Location : Geneva, Nations district

Genève

Nations

Principle : - Thermal network Direct cooling, heating, irrigation- Adaptation of existing buildings, ecobuildings

Birth : 1. Local project (pharmaceutical company)2. State Promote idea onto area ("district vision" Network)3. Local energy distrib. Expand the concept


GLN Activities : Renewable Energy Source

Network:

Lake water thermal exchange network (≈ 6 km – 4'700 m3/h) :

+ Energy recovery on return line

> Heating (heat pumps)> Irrigation (instead of potable water)

> Cooling (direct)

40 45°C

Theoretical thermal potential ≈ 33 MW (∆T=6°C)


Buildings : > Existing buildings : Adaptation to optimize use of the

network Regulation (Constant Flow rate, variable Temp.),

distribution systems

> Construction of eco-buildings : Minergie®

GLN Activities : Rational Use of Energy

OMPI 2

OMC 2

HP PPH

: Ecobuildings

: GLN perimeters (buildings)

Objectives GLN project (2010-2011) :~ - 30% convent. energy consumption~ - 40% CO2 reduction


GLN Activities : Others

Monitoring (Lake, buildings, network)

GLN

Research- Computer modelling (lake, buildings, thermal network)- Audit of 2 existing buildings ( Adaptation to a hydraulic network) Methodology to be developed & implemented- Methodology for envi. & energy district planning (WebGIS interface)

Training :- Syst. construction, Network (& building adaptation, Energy urban planning)

- Building technicians & owners, architects, engineers (+ Students, children)

Knowledge & results promotion

e i g

Ecole d’ingénieursde Genève


Project Status

• Network :– Blue (Provisions),

Green & Red (to build)

– 70% cooling capacity ("contracts")

– StartUp ≈ spring 2009

• Existing buildings

– (heating : fuel oil gas)

• Eco-buildings :

– At various stages

(SERONO = OK, College & Foyer ~ 2010, … OMPI II, OMC II)


Project Successes and Barriers

+ Strong public backing+ Public-Private partnership+ Competitive cost of "free" cooling

- Building owners are not project partners & customers reluctant to sign contracts

- Existing buildings = big technical challenges
