5 Monitoring Options Product Criteria selection Option 1 Option 2 Option 3 Currentcost Ecobox Efergy Lower cost Best utilities

6 Monitoring: devices Main advantage: discriminate consumption by services Per electrical circuits Per each equipment or appliance (fridge, ) Monitoring: Selection of WP6 experiment dwellings Before installation 1. Meeting to the Neighborhood Representative Committee (representing the neighborhoods) RE from de latin re, it means repetition NATO from de latin natus, it means born Mascot for the Awareness Campaign 2. Household survey 3. Neighbourhood volunteers for monitoring 4. Signed Authorization by homeowners for monitoring Signed Authorization by homeowners for monitoring

7 Monitoring: Household survey 500 surveys In a regional level General Data Appliances (fridge, oven, ) Heating & cooling Occupants of the house 40 household survey (of 56) 71% participation Hot water Results of the questionnaire to households participating in WP5 to select the ones participating in WP6 Usage of social and entertainment media by adult members of household SMS 80% Internet 43% None 20% Usage of social and entertainment media by adult members of household 0% 20% 40% 60% 80% 100% None Internet SMS Household appliances in use Programmabe controlle 0% High energy class applia 33% Low energy class applia 68% Household appliances in use 0% 20% 40% 60% 80% 100% High energy class appliances Low energy class appliances Use of home automation None 100% Simple 0% Sophisticated 0% Use of energy saving lightning NO 25% YES 75% Use of energy saving lightning 0% 20% 40% 60% 80% 100% NO YES Heating, cooling and DHW Stand alone electric he 28% Air conditionaing 73% Electric bolier DHW 20% Gas natural 63% Central heating 0% Heating, cooling and DHW Gas natural Electric bolier DHW Air conditionaing

8 Monitoring: basic modul CE Approvals: ETSI EN V2.1.1( ), EN , EN v , EN 60215:1989+A1:1992+A2:1994, IEC :2001(1st Edition) and/or EN :2001+A11:2004 Monitoring: NET SMART 16

9 Steps: monitoring Monitoring: number of dwellings Date July/August 2012 Apartament block Fontanares 8 Pio XII 7 Total 15 Number of dwellings monitorization

10 Monitoring: number devices installed EACH DWELLING 1 monitor- interface A general monitoring of the dwelling 6 DWELLINGs 1 Transmitter Or more (2) Monitor per electrical circuits kitchen appliances, lighting, ) 1 net smart 5 IAMS (INDIVIDUAL APPLIANCE MONITOR) Monitor or per each equipment or appliance (fridge, every light ) Manual and verbal instructions Personalization Instructions, more simple Time clock Chanels for equipment or appliance

11 Template for data collection Identification And contact ( , tel.) Identification devices and services Comments and schemes Registration of the monitoring Monitoring PIO XII: install process

12 Monitoring FONTANARES: install process Monitoring + audit

13 Manage the information Monitoring: input Consumption bills 1. Collecting consumption bills of the household monitorized. 2. Analyse utility bills 3. Compare to data of monitoring bill

14 Monitoring: Manage the information Conection Download by Number Frecuency USB VISITE 10 DWELLINGS INTERNET REMOTE CONTROL 6 DWELLINGS Once every 2 months 2 fontanares 4 PIO XII Problem: people off the modem at night and connects again when they need it. Bulletin on energy efficiency Personalized report Consumption for month,year: total, washing machine, refrigerator, air conditioning, Evolution energy consumption in a day, month, Estimated cost for each equipment or appliance

15 Bulletin: Energy saving tips for homes How Can You Save Energy changing your behavior consumer? 0 RED WITHOUT INVESTMENT Developed collection ENERGY SAVING TIPS (about 40 tips elaborated) BLUE MEDIUM INVESTMENT incorporating savings elements? GREEN MEDIUM INVESTMENT renovating your Home? Energy saving tips for homes Selecting relevant motivational themes In cold weather, focus on heating messages; in hot weather, highlight cooling. For the rest of the time, considering messages which deal with lighting or equipment.

16 Energy saving tips for homes Problem Solutions Savings Information OUTPUT Energy saving tips for homes Tip : Renewal of the contract conditions in the electrical supply Individual advices according to the realities in households Exemple: Interpretation of consumption data for billing, change of contracted power, saving money.

17 Audit 2012 Martins Residential Lettings How do the audit? Audit :Data collected during the audit phase Detecting Poor or inadequate insulation, moisture, building envelope leaks Infrared Camera FLIR i7-19,600 pixels 22 UNITS (15 FOR DWELLINGS INTERIOR + 7 FAÇADES EXTERIOR) Indoor temperature measuring device U12 Temperature and RH Data Logger Onset HOBO Two Channel USB Temperature/Relative Humidity Logger with 12-bit Resolution UNE-EN ISO 7726:2002 Ergonomics of the thermal environment - Instruments for measuring physical quantities. (ISO 7726:1998)

18 Audit : tools Tools developed by IVE procedures recognized by the government CURRENT STATE ASSESSMENT PHASE BUILDING CONSERVATION REPORT AND ENERGY ASSESSMENT Technical, Economic and sustainability criterias DOCUMENT ENERGY ASSESSMENT TOOLS SOFTWARER IMPROVED STATE ASSESSMENT PHASE CONSTRUCTIVE COMPONENTS CATALOGUE FOR BUILDING RETROFIT CERMA REHABILITATION Author: IVE CERMA-SOFTWARE Certification and evaluation of energy efficiency in buildings Audit : Methodology Begining Previous data (Geometry, orientation, ) Inspection (visual, tasting, instrumental,..) IN PROCESS Modelling: building envelope + facilities (hot water,heating..) Building evaluation (kwh/m2, kg CO2,..) Study possible improvements (tecnichal, economic,..) Strategy design conservation measures

19 Audit : Modeling Energy Performance Roof Façade Windows Building envelope construction solutions are characterized ACS Heating Cooling Services Diagnosis and action plan : Objectives % Reduction of energy consumption or CO2 Chance the current certification level Why not Nearly Zero Energy Building??? Obviously not now, BUT Short time Long time Proposal: Thinking the technical project doesn t finish in ELIH-MED: - The project is divided in different phases - It is necessary to develop a road map for each pilot project ( only design how to get nearly zero energy building) -They could to continue the works of improvement when they get more money (recapitalization in the future) -At the same time it is important to develop maintenance plan for the users ( guide about the actions to conserve the thermal performance of roofs, façades, and the solar water system, etc. and, also, how use them)

20 Diagnosis and action plan : output Cost economic optimum The area of the curve to the right of the economic optimum represents solutions that underperform in both aspects (environmental and financial). To prepare for higher energy or environmental targets (e.g. related to 2020), certain Member States might choose even stricter requirements than the economic optimum (left area of the curve). cost-effective constructive solutions of renovation for the improvement of envelope thermal behavior.
