BLOG: HVAC in 2024: 5 key takeaways and predictions for 2025

As we approach the end of 2024, it’s clear this year has been one with significant developments for the HVAC industry. From the UK government’s bold low-carbon commitments to the rapid adoption of hybrid working models, the sector is navigating new challenges and seizing fresh opportunities.

Looking ahead to 2025, its looking like the focus will remain strongly on innovation, sustainability and creating people-centric solutions that adapt to the evolving needs of buildings and their occupants.

Here's a round-up of key developments in 2024 and what we can expect in the coming year.

1. The hybrid working shift and its HVAC impact

Hybrid working continues to reshape how office spaces are designed and used. Recent research (from AWA’s fourth Hybrid Working Index) highlights that UK offices now provide just 56 desks per 100 employees with desk usage rising from 33% to 49%. This reflects a more strategic approach to space utilisation, where office attendance averages 1.65 days per week.

What’s next for 2025?
The shift to hybrid working creates opportunities for HVAC innovation. Systems must:

• Adapt to fluctuating occupancy levels: demand-based ventilation solutions will optimise air quality and energy efficiency.

• Provide decentralised solutions: tailored comfort for specific zones within a building is crucial as occupancy varies.

• Support retrofits: with real estate downsizing stabilising, the focus will shift to maximising the efficiency of existing spaces.

Beyond offices, the hybrid model’s influence extends to hotels, restaurants and leisure facilities, which are adapting to more flexible usage patterns. MAPUK is committed to delivering solutions that align with these evolving needs, ensuring buildings remain comfortable, productive and energy efficient.

2. The rise of decentralised systems

Decentralised HVAC systems have emerged as a game-changer, offering flexibility, efficiency, and scalability. These systems allow for customised energy management across different zones in a building, making them ideal for hybrid workplaces and commercial settings. For luxury hotels and high-end residential developments, decentralised systems are particularly attractive. These buildings demand bespoke comfort solutions tailored to individual rooms or spaces, enabling energy-efficient climate control that enhances the guest or resident experience.

What’s next for 2025?
As buildings strive to meet net-zero targets, decentralised systems will become key for both new builds and retrofits. 

3. Energy efficiency and retrofitting

Retrofitting remains one of the most impactful trends in the HVAC sector. Once again, decentralised ventilation and heat recovery systems have made retrofitting more accessible, delivering enhanced IAQ and significant energy savings for commercial and educational spaces alike.

What’s next for 2025?
As hybrid workplaces evolve, retrofitting efforts will focus on:

• Enhancing IAQ to support employee well-being.

• Reducing energy consumption during low-occupancy days.

• Offering modular upgrades that minimise disruption and deliver long-term efficiency.

4. People-centric building design

One of the most exciting shifts in 2024 has been the move toward people-centric buildings. This trend focuses on environments that enhance comfort, well-being productivity and operational efficiency.

What’s next for 2025?
The role of HVAC in fostering healthier spaces will expand. Key priorities include:

• Smarter metrics: leveraging IAQ data to support health and performance.

• Collaboration: architects, designers and HVAC engineers must work together to create integrated solutions.

• Flexibility: designing infrastructure that adapts to hybrid work patterns and evolving occupant needs.

5. The digital revolution: data-driven HVAC solutions

Technology continues to transform the HVAC landscape, with wearables and indoor air quality monitors enabling data-driven decision-making. This year, there has been an emphasis on preventive health care and well-being, where HVAC systems play a critical role.

What’s next for 2025?
Powerful data must be coupled with robust standards to maintain trust. Transparency and scientific validation will be essential for gaining consumer confidence.

Looking ahead

2024 has laid the groundwork for a healthier, more sustainable future. The HVAC industry is at a pivotal point, with the potential to lead the way in addressing critical challenges such as climate change, hybrid working and occupant well-being.

The path forward requires embracing three key principles:

• Innovation: pushing the boundaries of technology to develop smarter, more sustainable solutions.

• Collaboration: working across industries to deliver holistic outcomes that benefit both people and the planet.

• Transparency: backing claims with science to empower stakeholders with clear, accurate information.

At MAPUK, we’re excited to be part of this journey. By designing solutions and working in partnership with air technology experts LTG Akteingesellschaft, Climecon, SLT and Bevent Rasch our aim is to create spaces and buildings that work smarter, healthier and more sustainably.
