OPTIMIZINGOPTIMIZATION SOLUTIONS

AFTER Energy Saving Measures have beenpresented in the Newsletter #2 o the project.These Energy Saving Measures (ESMs) coveran exhaustive range o interventions on thesocial housing stock aiming at improving theenergy efciency o the buildings, their economicperormance both or the Social HousingOrganizations and their tenants.

Reminder : AFTER collects and improves EnergySaving Measures

An Energy Saving Measure can be described as

ollowed.An ESM:

is implemented in order to improve the energyconsumption o a building and related to heatingaspects, warm water or electric powering orheating equipment. its impacts can eventually be monitored andevaluated regarding kWh and heating energycosts. can be optimized/infuenced/present a potential

to be improved.

These ESMs gather a large range o interventionsthat have been listed as ollows

The objective o the second phase o the AFTERProject is now to optimize these ESMs fndingactions that will correct and improve theirefciency ater their implementation.

Optimizing Energy Saving Measures

An Optimization Solution is related to an ESMwhich show potential o improvement.Thispotential can concern the 3 ollowing objectives:- improve the economic model o the ESM.- enhance the energy efciency.- increase the social perormance and the

reception o the ESM by tenants.)

As a consequence the Optimization Solution canlead to several types o actions:

- management & strategic decision- technical intervention (control, maintenance,replacement) on the systems and equipment.- improve the reception o the ESM by tenants.

The objective is still to highlight simple and low-

cost interventions that will improve the savingslinked to an Energy Saving Measure.Optimization solutions have been proposed by theAFTER participating Social Housing Organizationswith the sustain o the Scientifc partners. Theseoptimizations will be tested during the heatingseason in order to measure and to assess theirimpact on buildings.

New energy contract with perormance objective and prot-sharing system with the operator containing :1) New prices negotiated on the gas price (withdrawal romthe historical regular price and indexation o the newprice on the evolution o the regular price in order to have acontinual delta.

2) New O&M contracts or equipment with perormanceobjectives and prot-sharing clauses.

3) Total guarantee and plan or the equipment replacement.

4) Modernization plan and ESMs identied in the originalcontract. The operator will give every year a modernizationand energy-saving plan to the SHO containing potential ESMs

to implement (and their prices).Several operators have been evaluated in order to conclude

the contract.

Web tools and energy inormation:

Remote reading o heating energy and hot and cold waterconsumption in individual apartments and visualisation oconsumption data to tenants on internet user web portal ingraphical and numerical orm plus outputs o comparisonwith previous periods consumption and with the otherapartments consumption anonymously.

Wireless radio requency meters o heating energy (RFthermometers), hot, cold water consumption are installed inapartments. Consumption data are transmitted via gatewayto application server where are stored and processed.Consumption is visualised on the web portal in real timeater each reading several times per day (hour).


Web portal use and impact improved thanks to directcommunication with the tenants on new supports andocusing particular targets: certicates in the entrance,

In order tochange/improve this situation Tenant inormation is plannedto be distributed October 2012. The Inormation will providesome general guidelines or living in a passive house aswell as more technical inormation o the equipment inthe dwelling. At the moment it is not possible to separate

Substitution o the two old twin boilers (Brand: Ferroli,Model: Linea II, power: 98 kW each) with one newCondensing boiler (model: YGNIS VARFREE 100, September2008, power: 92 kW). This boiler serves only the heatingsystem; tenants have single boiler (electrical, most o the

time) to produce DHW in their apartments.


Removal o the heat exchanger (in order to obtain a lowertemperature o return water and highest eciency) isimpossible because o the warranty o the system.Installation o an insulation cap or the heat exchanger whois not insulated can be a good compromise between the

present situation and the removal o the heat exchanger.This low cost intervention (300-500 euro) identied thanks toa RCx process could be disseminated ont he whole housingstock o ATC.
