HANDBOOK0. INTRODUCTION

The AFTER Handbook is the starting point othe AFTER global methodology .This Handbook will be used in the Inventoryphase in order to deliver an ID or thedierent ESMs collected by the partnersand to present some o the specicitiesregarding ther implementation.

The Handbook will be then completedregarding the characteristics o the 18 PilotESMs. These characteristics will be linked

with the identication o the ESMs and o theindicators aiming at precising their criteriao eciency.

0.1. CONCEPTUAL FRAMEWORK

The common conceptual ramework has the purposeto set the rame or a simultaneous assessment o theeconomic, environmental and social impact o EnergySaving Measures (ESMs), experienced by the SocialHousing Organisations (SHOs) during the last fveyears.

The conceptual ramework consists o1. An Inventory template will provide to the partners aramework to register the data o the ESMs inormingvarious perormance indicators or the assessment o

the economic, environmental and social impact o theESMs.2. A Handbook will oer defnitions o the perormanceindicators (perimeter, metering units,) to securethe comparability o the ESMs perormances and thescientifc quality o the evaluation o ESM.This Handbook will be completed in a frst time, withthe most important elements to complete in order toidentiy ESMs and some clues on the characteristics othe dierent WPs.Ater the selection o the Pilot ESMs, this Handbookwill be completed with specifc indicators related to

the ESMs the project will ocus on. This step will beaccomplished at the same the SHOs will proceed theevaluation o the measures.As AFTER covers a diversity o investments,interventions and actions, the Handbook is a work-in-progress that will be updated regarding how theproject will evolve.This Handbook is giving the specifcation o theperimeter, metering units, nature and specifcremarks to the ESMs to help the data fnding. Itsstructure ollows the Inventory rame.3. Typology lists will present an overview o genericESMs within the fve ocus areas: Management o

the housing stock, operation and maintenance o thebuilding stock, system replacement, retroftting andnew housing4.Factsheets will gather the inormation collected onAFTER ESMs.

HANDBOOK0. INTRODUCTION

0.2. GLOBAL PERFORMANCE INDICATORSFOR ESMs

The global perormance indicators analyze economic,energy and social perdormance o every ESM andpresents a comparable overview.The objective is to obtain at the end o theimplementation process a global understanding o oneESM efciency.Even i some qualitative inormation will improve andget more content or every ESM implemented, theAFTER Project ocuses on 3 main range o indicators.

Everyone o these global indicators are correspondingto one ambition. They will be completed during theprocess, i need be, by other indicators more adapted

to the specifc context and content o everyone o theselected Pilot ESMs.

Economic perormance

The economic efciency is related to a globalestimation o the costs impact or the implementationo an ESM and its benefts on the energy consumption.

This economic efciency will be mainly inormed andassessed thanks to two acts:

-the costs linked to the investment and the O&M costslinked with the investment-the costs linked to the specifed energy consumption.

These two battery o data can help us to determine

the payback period that can be defned by the timeit takes to cover initial costs. It can be calculatedrom the number o years elapsed between the initialinvestment, its subsequent operating costs and thetime at which cumulative savings o ESM oset initialcosts.

When there isnt any investment such as it appearsmost o the times in WP3 and WP4, it is suggested togive an economic value (additional initial cost in theinventory template) o the time spent to plan the ESM.

To be able to compare across countries, the paybackperiod should be calculated. See calculation toolenclosed in Annex D in the Handbook.

Energy perormance overall energy consumptionper m2 per year

Overall consumption is defned as the totalconsumption o fnal energy the summary odelivered energy by all energy carriers excludingindividual electricity.Meter readings rom the ats are used as the basis orthe data fnding.As a AFTER mainly ocus on the impact o energysaving measures related to the heating and thehot water, the indicators used to assess the energyperormance will be mainly consumption in kWh andm3.

Social perormance tenants awareness

The social perormance indicator may be the mostcomplicated impacts to assess. They both coverqualitative and quantitatives impacts.Quantitative data are classic indicators used in the

social housing to identiy to ollow their tenantssatisaction and mobility .These indicators can only becorrected and completed with qualitative data basedon the direct testimony o the tenants.

conditioned reerencefoor area

General remark: conditioned building area (or building volume)reers here and in the ollowing to that part o a building which issupplied by a heating system and/or an air-conditioning system.(air-conditioning means here at least cooling, not only ventila-tion)

conditioned gross oorarea

Conditioned oor area calculated on the basis o external dimen-sions (measured to the outside surace o external walls)

conditioned oor area Conditioned oor area calculated on the basis o internal dimen-sions (measured to the inside surace o external walls)The oor area may be the gross internal area (= total building areameasured inside external walls) or the net internal area (= totalbuilding area measured inside external and internal walls) - sincethe dierence is small we dont distinguish between both.The conditioned area is generally equal with the heated area or withthe air-conditioned area, dependend o which is the bigger one.

conditioned useul oorarea

Section o the conditioned net oor area primarily dedicated to theutilisation o the building, excluding unctional and circulation areas(excluding e.g. stair cases in all buildings, corridors in non-residen-tial buildings).

In ofce buildings the conditioned useul oor area is equivalent tothe net lettable area.

Specications & perimeterIn a general way, the indoor temperature is theaverage level o temperature inside the ats during theheating season. This indicator will be evaluated as aqualitative or a quantitative depending on the projectphase.

For both inventory and assessment phases, theaverage level o temperature inside the at will beestimated by the SHOs. I the SHOs are not able toprovide an average level o temperature resultingor example rom internal surveys or national social

housing associations, the deault value o indoorstemperature beore and ater ESM will be assigned at20C.

For testing phase, indoor temperatures will beevaluated i it is quite possible, or each at and eachroom o the at (bedrooms, kitchen, livingroom,...).Moreover, i there is some intermittence, two dierentindoor temperatures could be defned respectivelyor both occupancy and unoccupancy periods. Forexample: in the living room the indoor temperature is21 rom 7:00 AM to 10:00 PM and 19 or the rest o the

time. Based on the temperature pattern an averagetemperature in the at within the heating season willbe defned.

Those indoors temperatures will be collected:- as a qualitative way using dedicated surveys. Theresulting temperatures will then estimated by thetenants- as a quantitative way using temperaturemeasurements. It is recommended to use temperaturedata loggers to record the temperature data. Dataloggers are available to monitor a wide range oparameters such as temperature, humidity, voltageand current. Data is transerred to a PC with an USB orserial cable. A range o wireless data loggers are alsoavailable.

The indicators or economic perormanceshould indicate the lie cycle costs or anESM within its perimeter.AFTER mainly aims at identiy the privatecost eciency o an ESM or a SocialHousing Company.

Cost calculation diers rom one countryto another and rom one SHO to another(interest rates, cost o energy, legalnancing, etc...). The objective o theInventory is mainly to manage to identiyrelevant indicators regarding the costs ableto assess the eciency o one measure.

The tips regarding one ESM are supposed to highlightsome direct recommandations thanks to the SocialHousing Organizations experiences and bestpractices.

These tips will help to help to identiy relevantpractices in order to optimize the ESMs and someissues that may be related to these measures.The objective is to highlight qualitative points toimprove during the lie cycle o the measure.

The solutions can be both technical maintenancepoints or operational and management innovationsregarding a measure and can be implemented romthe beginning o its implementation to the post-management o the ESM.

6 main steps can be identifed in order to identiypotential tips:

- identication o the consumption and o theenergy saving measures: interventions and routinesto implement in order to identiy upstream thepotential savings .

- design and conception o the measure, planning othe implementation: technical and operationnaldefnition o the measure adapted to the context othe company (rameworks, tools).

- implementation and adaptation o the ESM: on-feldexperience and issues identifed.

- reception and optimization o the ESM by tenantsand users: potential o optimization linked withtenants education and awareness.

- maintenance, correction and improvement o theESM by SHOs sta: ollowing o the routines aterthe implementation.

- evaluation o the ESM and rating: integration o theESM in the SHOs asset management and standardtools.
