Are you embarking on the journey of a new residential property build? Among the flurry of decisions from flooring to kitchen finishes, there’s one crucial aspect that often doesn't receive the spotlight it deserves: the home ventilation system.
Choosing the right ventilation system is as much about creating a healthy, energy-efficient living space as it is about occupant comfort. So, how do you select the ideal solution for your new residential build?
Let's explore the ins and outs of home ventilation, what your options are, their differences in efficiencies and costs, and ultimately, what the right match for your individual needs might be.
Home ventilation systems: What are the options?
When it comes to mechanical home ventilation solutions, there are primarily two types of ventilation systems used in new residential properties; Mechanical Ventilation with Heat Recovery (MVHR) and Mechanical Extract Ventilation (MEV).
Mechanical Ventilation with Heat Recovery (MVHR)
MVHR systems are the gold standard for energy efficiency and air quality. They work by extracting warm, stale air from inside the home and using it to heat fresh incoming air through a heat exchanger. MVHR systems are especially beneficial in colder climates, providing substantial energy savings and consistently fresh air.
Continuous Mechanical Extract Ventilation (MEV)
Unlike MVHR, MEV systems continuously remove moisture-laden air from kitchens, bathrooms, and utility rooms. Available as either centralised of decentralised, fresh air enters passively through wall or window vents before filtering through the MEV system. This type is simpler and generally lower in initial costs but lacks the heat recovery–and therefore the energy efficiency–benefits of MVHR.
Comparing energy efficiency
Energy efficiency is essential as the UK marches towards net zero goals. MVHR systems significantly lead the pack here, with efficiency ratings of up to 95%. They recover heat from extracted air, substantially cutting down on heating bills. While initial investment is higher, the long-term energy savings are impressive.
On the other hand, MEV systems provide moderate efficiency. They ensure continuous air extraction but without heat recovery, which might mean increased heating demands and therefore, higher energy consumption.
Extract fans, while energy-efficient individually, do not impact overall home heating efficiency as significantly, as they don’t contribute to any form of heat recovery.
Evaluating costs
Let's face it; budgets are pivotal in new residential property build projects. Initial investment costs vary widely, but thinking long-term, it’s important to balance budget and performance.
- MVHR systems: Can cost between £700 and £5000, depending on house size, ducting requirements, and system complexity. Consider these costs as investments that provide long-term returns through reduced energy bills.
- MEV systems: Generally cost between £160 and £500, which can be attractive to budget-conscious builders who still need effective ventilation solutions.
- Extract fans: Usually priced from £50 to £100 per unit, these are ideal for targeted, minimal extraction, but less effective for whole-home ventilation.
The price point of a venilation system isn’t straight forward when you think about line items like energy bills and maintenance costs; consider upfront costs against long-term energy savings and comfort gains when making your decision.
Why assessing your air quality needs matters
Indoor air quality profoundly influences occupant health, comfort, and even home durability. Before choosing a ventilation system, evaluate factors such as humidity levels, pollution exposure, and insulation and airtightness levels.
If you're building a highly insulated home with tight seals—as many modern homes are—then MVHR systems become particularly advantageous. They not only enhance indoor air quality but also prevent mould, dampness, and condensation issues.
Homes located near busy roads or industrial zones might also benefit significantly from MVHR, as it filters pollutants efficiently, ensuring that only clean air circulates inside.
The importance of specifying for architects, contractors, and developers
For architects, contractors, and developers, specifying the right home ventilation system at the specification stage profoundly influences construction efficiency, long-term property value, and occupant satisfaction.
When specifying a ventilation solution, clarity and precision are key. Architects and developers need systems that effortlessly align with their project's design ambitions, sustainability targets, and budget constraints.
Contractors particularly benefit from clearly specified systems that work with other construction components. With well-defined product specifications, installation becomes quicker, reducing onsite adjustments or retrofits. This helps maintain project timelines and keeps construction within budget.
From a developer’s perspective, specifying robust and recognised ventilation solutions can enhance your project’s market appeal. By aligning your development with leading ventilation technologies, you’re offering buyers long-term reliability, exceptional air quality, and energy efficiency—key selling points in a competitive market.
Working with a trusted ventilation partner from the outset ensures fewer complications, smoother project delivery, and ultimately, significant cost efficiencies. Partnering with a reputable manufacturer guarantees detailed product specifications, comprehensive technical documentation, and end-to-end support throughout the project timeline.
Steps to take before installing a home ventilation system
To set your new property build up for success, follow these pre-installation steps:
- Assess the property’s airtightness by conducting air permeability tests.
- Calculate ventilation requirements in accordance with Building Regulations, specifically Part F in the UK.
- Design the ventilation layout with optimised airflow paths for efficiency.
- Plan maintenance accessibility to ensure the system is easy to maintain and service.
Conclusion
New homes deserve the best ventilation solutions. Whether you’re a self-builder undertaking renovations, a developer on the hunt for the right product, or a contractor looking to simplify the construction process, being clear on what your new build needs are and understanding your options is the critical first step.
From there, making the right choice of ventilation systems partner is a sure-fire way to guaranteeing new build success. With the right partner by your side, you’ll be equipped to choose a home ventilation system that ensures comfort, sustainability, and cost-efficiency.
