[Energy Audit BIL](/en/energy-audit-bil) 2. Sample energy audit Real case — Echternach, Luxembourg # What does an ImmoPass energy audit look like? Explore a real energy audit performed on a house in Echternach. 8 areas analysed, costed action plan, subsidies identified. ## Energy performance 83% consumption reduction Current performance 280 kWh/m² an After recommended works 49 kWh/m² an ## Current building condition Roof insulation Original 1969 roof uninsulated, 2006 extension OK Wall insulation Original walls uninsulated, 2006 extension insulated Windows & frames 2006 PVC double glazing — to be replaced with triple Floor insulation No insulation observed during inspection Heating system Buderus LOGANO GB125 boiler (2015) — functional Hot water Produced by Buderus boiler — adequate Ventilation No mechanical ventilation system installed Renewable energy No renewable energy installation ## Recommended action plan The architect defined 6 priority work phases, with estimated budgets and available subsidies. 1 ### Floor insulation Sprayed polyurethane floor insulation (XPS 12cm + PUR 8cm) Budget 42 840 € Subsidy 1 904 € Label after E 242 kWh/m² an 2 ### Dual-flow ventilation Zehnder Comfoair 350 installation — max 1 air change/h Budget 15 000 € Subsidy 6 750 € Label after D 208 kWh/m² an 3 ### Exterior wall insulation External mineral wool insulation 16cm (R = 4.55 m²K/W) Budget 25 662 € Subsidy 5 922 € Label after C 153 kWh/m² an 4 ### Window replacement Triple glazed wooden frames (Uw = 0.74 W/m²K) Budget 48 480 € Subsidy 3 636 € Label after C 122 kWh/m² an 5 ### Cellar ceiling insulation Ceiling insulation from cellar / unheated space Budget 2 260 € Subsidy 904 € Label after B 108 kWh/m² an 6 ### Roof insulation Internal mineral wool insulation 18cm (R = 5.14 m²K/W) Budget 23 040 € Subsidy 6 400 € Label after A 49 kWh/m² an Total works €157,282 Total recoverable subsidies €25,516 Budgets are indicative estimates. Subsidies are subject to change by the regional authorities. ## What the audit revealed ### Strengths - Recent boiler (2015) still functional - 2006 extension properly insulated - PVC windows in good overall condition - Quiet location in Echternach - High potential for energy class improvement ### Areas of concern - No floor insulation — major thermal bridge - Original roof (1969) completely uninsulated - Original walls with no thermal insulation - No mechanical ventilation system - Current performance of 280 kWh/yr·m² (class H/I) - No renewable energy installed ## Auditor's conclusion > Marie Boell — Certified Energy Auditor > > "The building has considerable energy renovation potential. With a 6-step action plan totalling approximately €157,000, it is possible to go from 280 kWh/yr·m² to 49 kWh/yr·m² — a reduction of over 82%. Available subsidies (~€25,500) significantly reduce the net cost for the owner. A phased approach allows the investment to be spread over 5 to 10 years." ## What this audit would have enabled ### Plan a coherent renovation A 6-step action plan with clear priorities, rather than a chaotic and costly approach. ### Maximise available subsidies €25,516 in identified subsidies — without the audit, some of these grants could have been missed or incorrectly applied for. ### Budget before committing Knowing the full renovation will cost ~€157,000 allows you to negotiate the purchase price or plan your financing. ## Download the full report Browse the full report as delivered to the client.
