Usually included
- ERV or HRV unit logic, fresh-air supply, extract, filters, balancing and commissioning assumptions.
- Typical villa-level controls and handover records.
Regional model
ERV / HRV system cost for villa
ERV and HRV systems shift a villa from basic ventilation toward managed indoor air quality. They also shift the budget from local fans toward ducts, filters, controls, service zones and balancing. This guide helps determine when that premium step is justified and how much it usually costs.
Budget snapshot
Location Regional model
Planning range IDR 220M-1.35B / villa
Best for Premium villas that need ERV or HRV budgeting with fresh air, balancing, filters and access included from the start.
Example planning scenarios
| Scenario | Area / basis | Specification | Planning range | Unit range | Important note |
|---|---|---|---|---|---|
| Small premium villa ERV | 180-260 m² villa | ERV unit, basic supply/extract routes, filters and commissioning checks. | IDR 220M-480M | IDR 1.2M-2.0M / m² served area | Useful when air quality and comfort are part of the guest promise. |
| Large villa balanced system | 320-550 m² villa | Multiple zones, larger duct routes, balancing, service hatches, stronger controls and O&M records. | IDR 640M-1.35B | IDR 2.0M-4.0M / m² served area | The upper band reflects projects that want real measured performance at handover. |
How to use this guide
Use this page when the project wants a more premium IAQ promise than local exhaust can provide.
Budget the upper band when measured balancing and maintenance access are non-negotiable.
Scope assumptions
Usually excluded or priced separately
- Commercial smoke systems, specialist IAQ sensors and high-end BMS packages.
- Architectural rework due to late ceiling coordination.
What changes the number
- Filter access and maintenance corridors determine whether the premium system stays usable after handover.
- Balancing and commissioning records are essential because the system promise is performance-based.
- Fresh-air intake and exhaust positions affect facade, hygiene and noise risk.

ERV / heat-recovery ventilation
Balanced ventilation system that exchanges indoor and outdoor air with heat or energy recovery.
Fresh-air supply
Controlled intake of outdoor air into occupied spaces.
Airflow balancing
Measurement and adjustment of air volumes so a ventilation system performs as intended.
Filter access
Service clearance and access route needed to inspect, remove, and replace HVAC filters safely.
Indoor air quality
Practical measure of how healthy, comfortable, and usable indoor air feels for occupants.
FAQ
Is ERV or HRV necessary for every villa?
No. It becomes most useful where the project targets premium comfort, more controlled indoor air quality, or reduced dependence on open-window ventilation.
Why is balancing part of the budget?
Because without balancing the system may be installed but still fail to deliver the promised airflow, pressure relationships and comfort.
