Certified Passive House Designer / Consultant study plan

Certified Passive House Designer / Consultant · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Building envelope: thermal insulation, thermal bridges, airtightness and construction details & Passive House principles, certification criteria and the PHPP

  • Reproduce from memory the Passive House certification limits (heating demand, primary energy, airtightness, overheating frequency) and state which apply to retrofit vs new build

  • Explain the three heat-transfer mechanisms through the envelope and calculate U-values for a homogeneous layer stack and for a layer with a repeating metal fastener

  • Sketch five typical thermal-bridge details (balcony slab, window reveal, floor slab at foundation, roof parapet, partition junction) and annotate the insulation continuity line

  • Quantify the difference between a point thermal bridge and a linear thermal bridge in PHPP input terms and identify which psi-values dominate a typical detached house

  • Set up a personal reference sheet of certification criteria and U-value reference values for your climate zone

Your checkpoint

A one-page annotated detail sheet with five hand-drawn junction sketches, each with the insulation line, calculated or sourced psi-value and a note on the dominant heat-loss path

Week 2

Building envelope: thermal insulation, thermal bridges, airtightness and construction details & Windows, doors and solar control: glazing, frames, installation and shading

  • Design an airtightness concept that names the airtight layer on every building element and shows how it is carried across each junction

  • Interpret a blower-door result: convert n50 to the PHPP-relevant infiltration rate and explain which leak locations explain a given n50 value

  • Compare frame construction types (timber, aluminium with thermal break, PVC, composite) by frame U-value and by installation thermal-bridge penalty

  • Select glazing for a given orientation using g-value, Ug and solar-control trade-offs, and justify the choice for south vs west facades

  • Detail a window installation that minimises the installation psi-value, including the sill, the reveal and the connection to the airtight layer

Your checkpoint

A window schedule for a hypothetical project: at least six windows with orientation, frame type, Ug, g-value, installation psi-value and a one-sentence justification each

Week 3

Windows, doors and solar control: glazing, frames, installation and shading & Ventilation and indoor air quality: ventilation concepts, heat recovery, duct design and summer comfort

  • Calculate the effect of external movable shading, overhang geometry and fixed fins on summer solar gains for a south and a west window

  • Size a ventilation system for a defined dwelling: derive supply and extract air volumes from occupancy and from the minimum hygienic air-change rate

  • Explain heat-recovery efficiency, frost protection strategy and the difference between a central and a decentralised unit with heat recovery

  • Lay out a duct network that keeps pressure drop low: justify duct routing, silencer placement and the position of the unit inside or outside the thermal envelope

  • Identify the indoor-air-quality parameters that Passive House certification checks and how a ventilation concept addresses humidity, CO2 and pollutants

Your checkpoint

A ventilation concept for a three-bedroom dwelling: air-volume table per room, unit specification with heat-recovery efficiency, duct routing sketch and a shading calculation for the two most exposed windows

Week 4

Heating, cooling, domestic hot water and renewables: load calculation, distribution and generation & Energy balance, PHPP calculations and verification: heating demand, primary energy, summertime and economics

  • Calculate the design heating load using the PHPP method and explain why the peak load, not the annual demand, sizes the generator

  • Size the domestic hot water system for a defined occupancy and compare storage losses for an internal vs external cylinder

  • Compare heat generators (air-source heat pump, ground-source heat pump, district heat, pellet boiler) on primary-energy factor, seasonal performance and suitability for a low-load house

  • Explain how the primary-energy renewable (PER) factor changes the choice of generator and which factors you must look up rather than assume

  • Work through a full PHPP verification: enter climate, areas, U-values, thermal bridges, ventilation and gains, then read heating demand, primary energy and overheating frequency

Your checkpoint

A completed simplified PHPP-style calculation for one reference dwelling, plus a generator comparison table showing primary energy and a recommendation with reasoning

Week 5

Energy balance, PHPP calculations and verification: heating demand, primary energy, summertime and economics & Passive House principles, certification criteria and the PHPP

  • Run a sensitivity analysis: change insulation thickness, window quality and airtightness one at a time and record the effect on heating demand

  • Distinguish useful solar gains from overheating risk and use the summer-verification outputs to decide whether shading or night ventilation is the better fix

  • Explain the difference between heating demand, heating load and delivered energy, and where each appears in certification

  • Identify the most common PHPP input errors that cause a failed verification and describe how each is caught in review

  • Reconcile a certification result against the economics: compute simple payback of an envelope upgrade versus a heat-pump upgrade

Your checkpoint

A sensitivity table with at least six parameter variations, the resulting heating demand and overheating frequency for each, and a two-paragraph conclusion on which measures give the most demand reduction per unit cost

Week 6

Quality assurance, construction supervision, commissioning and certification process & Building envelope: thermal insulation, thermal bridges, airtightness and construction details

  • Write a commissioning sequence for the ventilation unit covering air-volume measurement, filter check, frost-protection test and handover documentation

  • Build an inspection checklist that verifies the airtight layer at the stages when it is still visible (pre-cladding, pre-plasterboard)

  • Describe the certification process end to end: documentation package, verifier review, on-site checks and the conditions attached to a certificate

  • Explain how construction supervision catches thermal-bridge and airtightness defects, and what evidence a certifier expects from site photographs

  • Plan the blower-door test: timing, preparation, which penetrations are temporarily sealed and how results are documented

Your checkpoint

A site quality-assurance pack: airtightness inspection checklist, ventilation commissioning protocol and a blower-door test plan with pass/fail criteria

Week 7

Passive House principles, certification criteria and the PHPP & Energy balance, PHPP calculations and verification: heating demand, primary energy, summertime and economics & Quality assurance, construction supervision, commissioning and certification process

  • Review all seven domains against a self-written syllabus and flag the three weakest areas with specific gaps

  • Re-derive the certification criteria and the PHPP verification logic without notes, then check against your reference sheet

  • Practise interpreting a written project description and deciding which certification class it would achieve

  • Explain the roles of designer, certifier and site supervisor in a way you could present to a client in two minutes

  • Revisit the five thermal-bridge sketches from week 1 and correct any errors you now spot

Your checkpoint

A gap analysis listing every domain with a confidence rating, the three weakest topics with a written explanation of each, and a corrected version of the week-1 detail sheet

Week 8

Passive House principles, certification criteria and the PHPP & Building envelope: thermal insulation, thermal bridges, airtightness and construction details & Windows, doors and solar control: glazing, frames, installation and shading & Ventilation and indoor air quality: ventilation concepts, heat recovery, duct design and summer comfort & Heating, cooling, domestic hot water and renewables: load calculation, distribution and generation & Energy balance, PHPP calculations and verification: heating demand, primary energy, summertime and economics & Quality assurance, construction supervision, commissioning and certification process

  • Complete two full-length timed practice sets under exam conditions and score them by domain

  • For every wrong answer, write the correct reasoning in one sentence and link it to the relevant PHPP input or construction detail

  • Drill the numeric skills that appear most often: U-value, psi-value penalty, ventilation air volumes, heating load and primary energy

  • Rehearse explaining a construction detail and a PHPP result aloud, as you would in a scenario-based question

  • Finalise a one-page formula and criteria sheet you can review in the last days before the exam
