Ballyogan Square

Dun Laoghaire Rathdown County Council

Ballyogan Square

Phase 1 of the Ballyogan Residential Development (67 Units) has recently been completed on behalf of Dun Laoghaire Rathdown County Council, with Phase 2 (52 Units) Detailed Design and Tender Production also recently completed. Phase 1 consisted of 67 individual Housing Units constructed to Passivhaus Standard and an A1 Energy Rating. Metec undertook the most challenging roles in this medium-density development – Building Lifecycle Assessment, Energy/Part L compliance, Site Lighting (Bat-sensitive) and Mechanical & Electrical Exemplary Design.

Challenges

Achieving the Client’s requirement for compliance with Passivhaus Standard, Remote Energy and Air Quality Monitoring, Acoustic and A1 Energy Rating was an incredible challenge for Metec and the Architect. We worked closely with the Architect and Passivhaus Consultant, suggesting changes to layouts, depths of rooms and servicing strategies where required to achieve this challenging target.

Successes

The certification to A1 Energy Rating Standard and the confirmation of Passivhaus Standard point to the success of Metec’s approach throughout this challenging project. Metec have enjoyed a long-standing relationship with Dun Laoghaire Rathdown County Council, and continue to provide expert advice and design to our valued client.

Metec Solutions

Metec pushed the Fabric-first approach from the outset, with strong emphasis placed on Insulation Levels, elimination of Thermal Bridges, Airtightness, Triple-Glazing and Passivhaus-Ce3rtified Heat Recovery Mechanical Ventilation to each unit. The Mechanical & Electrical strategy included Nilan’s Passivhaus certified Compact P Hot Water and Heat Recovery Ventilation Unit with additional Solar PV. All Air Inlets/Exhausts were located away from the adjacent M50 Motorway to eliminate acoustic concerns. Metec specified Internal Air Quality and Energy Monitors to meet the Client’s requirements, including a landlord WiFi system to allow remote access to monitor these important criteria.
