Pre-Planning Checklist: Feasibility, Site, and Goals
Start by confirming your project goals and how you’ll measure success, such as indoor comfort, heating demand, and sound performance. A clear brief helps align designers, engineers, and builders early so decisions stay consistent through the build. Review your passive house builders dublin site conditions, including orientation, prevailing winds, shading from trees or neighbouring buildings, and access for materials. These factors directly influence how well the building envelope performs and how efficiently ventilation can be controlled.
Next, verify constraints that affect the design, including planning requirements, boundary limitations, and any heritage or conservation considerations that may apply. Ask whether your chosen approach supports airtightness targets and high-performance insulation without creating buildability issues. Collect baseline information such as existing floor levels, wall thicknesses if you’re extending, and any damp or moisture concerns. Addressing these items before construction prevents costly rework and improves the likelihood of achieving low energy use.
Design and Specification Checklist: Airtightness, Insulation, and Ventilation
Demand a specification that treats the building envelope as one continuous system, not a collection of parts. Confirm the insulation strategy for walls, roof, and floors, and ensure thermal bridging is planned rather than left to chance. kitchen extension dublin Pay attention to window and door selections, including frame material, glazing type, and installation detailing that supports airtightness. Well-specified components reduce heat loss and help maintain stable indoor temperatures across seasons.
Ventilation is central to passive performance, so include a balanced mechanical ventilation system with heat recovery as part of the core plan. Ensure duct routes are designed for minimal pressure loss and that commissioning tests are scheduled. Plan for air leakage control by using appropriate membranes, taped junctions, and carefully sealed penetrations. When ducting, electrical runs, and plumbing are coordinated early, the final airtightness outcome is far more consistent and easier to verify.
Build Quality Checklist: Detailing, Supervision, and Testing
During construction, insist on workmanship checks at key stages rather than waiting until completion. Early verification focuses on airtightness layers, insulation continuity, and the quality of window/door installations. Require attention to corners, junctions, and service penetrations, since these are common sources of leakage and thermal bridging. A strong site culture helps trades coordinate so seals and membranes are not damaged during later works.
Plan for formal testing and commissioning, including blower-door style airtightness verification where appropriate. Confirm that ventilation commissioning includes airflow balancing and that system controls are correctly set for reliable operation. This means coordinating junctions around floors, walls, and openings so the extension does not become the weak point in the airtight envelope.
Conclusion
Using a checklist approach helps you keep passive performance goals practical, measurable, and achievable from first decisions through handover.
