Cool and Comfortable Without an Open Window

When the window has to stay shut, comfort is a design decision, not a bigger air conditioner.

Designing for comfort on a noisy, exposed or humid site without relying on an open window. How to name the constraint precisely, keep heat out before you pay to remove it, move air through secure, acoustic and filtered paths, and meet the ventilation, make-up air and condensation requirements a sealed house still has.

Introduction and objectives

Why a shut window is a design constraint rather than a reason for more equipment, and the four things you will be able to do on your next house.

Module 1 11 min

Why the Windows Stay Shut

Noise, security and privacy, smoke and particles, humid nights and client preference, and what each one rules out and still allows.

Module 2 11 min

Keep the Heat Out First

The roof, glazing and shading where the window cannot open, when thermal mass helps, internal gains and what a sealed house does with heat.

Module 3 11 min

Moving Air and Heat Without an Open Window

Secure and acoustic ventilation paths, balanced filtered ventilation, ceiling fans, night purging and air conditioning sized and zoned properly.

Module 4 11 min

Comfort, Compliance and the Running Cost

The ventilation requirement and its mechanical alternative, make-up air, condensation, the energy budget, commissioning and documentation.

Case studies 4 min

The main road house and the bushfire site

A sealed house with no make-up air that pulled the heater flue backwards, and a bushfire design that gave away free night cooling.

Summary 2 min

Key takeaways

Six habits to carry into the next house on a hard site.

Finish

Final quiz and certificate

Ten practice scenarios. Pass and the certificate goes straight into your dashboard.

Intermediate. For designers who document Class 1 houses on noisy, exposed, overlooked or humid sites. Covers naming the constraint, heat exclusion, ventilation and air movement without an open window, and the ventilation, condensation and energy provisions. It is technical education, not a substitute for an acoustic consultant, a mechanical services designer, a bushfire practitioner, an accredited energy assessor or your certifier, and names no product or supplier.

Who it is for

Written for the people who design houses on sites where the window cannot do the work.

Building Designer

You choose the comfort strategy and document the ventilation route the house relies on.

1 formal CPD point

Residential Drafter

You draw the openings, the shading and the vents that decide whether the room complies.

1 CPD point

Practice Principal

You carry the complaint when a compliant house turns out to be uncomfortable to live in.

1 CPD point, with audit-ready records

Renovation and Extension Designer

You add rooms to houses on main roads and small lots, where the old openings no longer work.

1 CPD point

Project Home Designer

Your standard plans land on noisy and humid lots, so the constraint has to be designed in.

1 CPD point

How it is recorded

A building designer

1 formal CPD point. Your certificate, the learning outcomes, the module outline and your quiz result are kept in your dashboard, so you can show what you studied if your CPD is audited.

An architect

1 formal CPD point. Aligned with NSCA 2021 performance criteria PC26, PC28, PC31, PC33 and PC46.

A drafter, renovation or project home designer

1 hour of CPD on residential comfort and ventilation, recorded on your certificate for your registration body or scheme.

CPD On Demand is not a registered training organisation and courses are not accredited by any registration body. Each course is aligned with the relevant competency frameworks and gives you the records to evidence it. CPD rules differ by registration body and state, so check with yours if you are unsure.

  • Analyse the constraint on a site and determine what it rules out and what it still permits.
  • Apply the envelope measures that reduce cooling demand before any equipment is chosen.
  • Select the air movement and ventilation strategy suited to the specific constraint.
  • Size and zone air conditioning so it completes the strategy rather than replacing it.
  • Evaluate the design against the ventilation, make-up air and condensation provisions.
  • Document, commission and hand over the system so it survives the builder and the client.

Questions

Before you enrol.

Yes. The course is national. NCC 2025 applies in Victoria, the Australian Capital Territory and Western Australia, and NCC 2022 as amended continues in New South Wales, Queensland, the Northern Territory, Tasmania and the South Australian building volumes. The ventilation, condensation and energy provisions the course relies on are materially the same in both, and acoustic requirements near transport corridors are set by each state’s planning instruments, so confirm what applies to each project.

Start, stop and finish later. Progress is saved and the course stays in your dashboard.

Yes, on passing the final quiz. It is stored in your dashboard alongside your other CPD records.

No. Sizing ducts and specifying acoustic treatment belong to the mechanical designer and the acoustic consultant. This course is about the decisions that sit with you: naming the constraint, the envelope, choosing the strategy, checking the ventilation requirement and briefing the specialists.

Yes. Team packs start at $579 for six courses shared across your practice.

No. Every course is product neutral. No window, ventilation, screen or equipment brand is named, and there is no sales pitch at the end.
