Importance of monitoring
2
Lyon Confluence is one of the first very energyefficient district built in France
It is a kind of “prototype”Ambitious energy performances are targeted(<50 kWh/m2/year; 80% REN for heating)
New systems and techniques has been usedlot of money and time have been spent in this project
Thus, monitoring is necessary as to:Assess actual energy performances of the buildingsBetter understand what work and what do not work
Global ratios are not sufficient to achieve this goalWe need explanatory variables (data at a 10 minutes time step)
RENAISSANCE es un proyecto del programa CONCERTO co-financiado por la Comisión Europeadentro del Sexto Programa Marco
What is monitored?
Qualify the outdoor conditions(T°C, humidity, solar radiation, wind)
Actual operating conditions of buildings:comfort (T°C & humidity) and air flow (quality of the envelopeairtightness)
Heating consumption (both at dwelling level and atsubstations/stations level)
Hot water consumption
Ventilation electricity consumption
Electrical consumption (dwellings and common areas)
Indoor air pollution (CO2 and VOCs : Volatile OrganicCompounds)
All common areas and systemsAbout 10% of the dwellings

Examples of results (1)
kWh/m² heated area by usesGreen house effect gases balanceReconstitution of the thermal and energybalance by usesEvaluation of the maintained comfort(winter/summer)Analysis of the occupancy modes and of thebehaviour of the inhabitants

Strengths and weaknesses ofthis approach
Strengthsexplanatory variables(data at a 10 minutestime step)
Accurate results andin depth analysis
Possibility to identifythe impacts ofoutdoor environmentand/or inhabitantsbehaviors
WeaknessesNo intermediary (orlive) results
Need to wait 1 yearof measures + 6months of analysis
No interactionpossible withinhabitants or M&Ocompanies

Conclusions &Recommendations
Detailed monitoring is essential to: evaluated actual energy performance of thebuildingTo precisely identify the main consumptionitem and work on them for next buildings(learning by doing process)
PV monitoring & follow up enables toidentify defaults/failures and avoid looseof production
