How to Design HVAC Systems for Co-Working Spaces in London



Co-working spaces are some of the most challenging environments for HVAC designers. They combine open-plan areas, private offices, meeting rooms, kitchens, and high-traffic zones, all with different cooling, heating, and ventilation needs.

London’s climate, older buildings, and mixed-use designs add even more complexity.
This guide explains how to design HVAC systems for co-working spaces that deliver comfort, energy efficiency, and full flexibility for tenants.

1. The Challenges of HVAC in Co-Working Spaces

Co-working buildings have highly variable occupancy patterns:

• Morning high demand

• Afternoon fluctuations

• Meeting rooms with sudden load increases

• Hot-desking areas with dense electronics

• Kitchens generating heat and smells

HVAC must handle rapid temperature swings and frequent heat load changes.

---

2. Ideal HVAC Systems for Co-Working Spaces

A) VRF Systems — Best Choice

VRF allows:

• Independent temperature zones

• Energy-efficient modulation

• Integration with smart controls

• Minimal operational noise

VRF is perfect for buildings with mixed room types.

---

B) Cassette Units — Best for Open Areas

Cassette units offer:

• 360° airflow

• Uniform cooling

• Quiet operation

• Easy maintenance

Ideal for open desks and workstations.

---

C) Ducted Systems — Best for Private Rooms

Ducted AC provides:

• Completely hidden installation

• Low-noise operation

• Controlled airflow

• Good for smaller offices

---

D) Fresh Air & Ventilation Systems

Co-working spaces require fresh air to support:

• High occupancy

• CO₂ reduction

• Odour removal

• Compliance with Part F UK Building Regulations

Recommended systems include:

• MVHR

• HRV

• ERV

• Dedicated fresh air ducting

---

3. Zoning Strategy

Zoning is the foundation of proper HVAC in co-working setups.

Recommended zones:

• Reception

• Open workspace

• Private offices

• Meeting rooms

• Kitchen

• Phone booths

• Event rooms

Each zone needs an individual thermostat.

---

4. Noise Control

People work, take calls, and record audio — noise must stay minimal.

Recommended noise levels:

• Open-plan: < 35 dB(A)

• Meeting rooms: < 30 dB(A)

• Quiet zones: < 28 dB(A)

Use:

• Duct silencers

• Low-noise cassette units

• VRF with inverter fans

---

5. Airflow Design

Good airflow creates comfort without drafts.

Techniques:

• Ceiling diffusers for private rooms

• 360° cassettes in open areas

• Low-velocity ducting

• Coanda airflow usage

• Avoid placing units directly above workstations

---

6. Energy Efficiency

Energy savings are essential in large shared offices.

Use:

• Inverter AC

• R32 refrigerant

• Smart thermostats

• Motion sensors

• Night setback mode

---

7. Smart Controls and Automation

Co-working spaces benefit greatly from central control:

• BMS integration

• Wi-Fi thermostats

• Remote monitoring

• Weekly schedules

• Automatic start/stop

Apps like Onecta, MELCloud, and GREE+ allow easy management.

---

8. Air Quality for Shared Offices

Air quality is critical for health and productivity.

Recommended:

• PM2.5 filters

• CO₂ sensors

• Fresh air intake

• Improved filtration

• Humidity control (40–55%)

---

Conclusion

Co-working spaces require a carefully planned HVAC strategy to balance comfort, zoning, noise levels, and high occupancy.

VRF systems, cassette units, ducted solutions, and proper ventilation create a stable, comfortable environment that adapts to rapid changes in temperature and usage.

For London’s growing co-working market, smart, efficient HVAC design is essential for a productive workspace.
