The importance of air conditioning and ventilation in a loft conversion

Loft conversions are a great way to add additional space to your home and increase the value of the property. During your planning process it is essential to consider air conditioning and ventilation solutions for your new loft conversion. 

Let’s take a look at the key points to consider.

Why is ventilation important?

There is much more to consider when it comes to loft conversion than just interior décor. Similar to any other room in your home, your new conversion will need proper ventilation. This is to ensure that the space complies with building regulations and is safe to use.

Ventilation requirements

In order to meet building requirements, you will need to meet the following requirements:

A window with an opening equivalent to 5% (1/20th) of the floor area

Background ventilation (also called trickle vents or night vents) of 8000 mm², which can be closed to prevent draughts

Local Authority Building Control

In addition, it is important to note that when you convert your loft into a habitable room, you are changing the environment of the space. Lofts are used to expel damp. Once converted its purpose has changed so you will need to add ventilation paths to suit the requirements of the space. You can find a full guide on loft conversions here.

Why is Air Conditioning important?

Lofts and attics can become very hot and humid. An AC system will not only help regulate the temperature in your loft but hosts a whole range of other benefits. Having an air conditioning system in your loft conversion will help to reduce the chances of moisture build-up, lower the cost of heating bills, and maintain air quality and humidity levels.

Air Quality Control

Since we spend the majority of our time indoors, our indoor air quality has a direct effect on our health. Without proper ventilation, the air in our homes can become harmful to breathe. Air conditioners have the added benefit of being good at removing airborne pollutants. They stop dust, allergen, bacteria and hair particles from circulating the airspace in your home. This is particularly useful in the summer months for those who suffer from allergies.

Humidity control

Not only can AC systems remove heat from a room but they are also useful for regulating humidity levels. The optimal humidity level for the average home is somewhere between 30% and 70%. If the humidity levels in your home are too high, you are more likely to experience excess damp and mold. Both of these can cause serious health issues if not controlled. AC systems regulate humidity levels by removing hot and humid air and replacing it with dry cool air.

Ideal AC Units for loft conversions

Wall Mounted Units

Wall mounted air conditioning units are ideal for small spaces and are therefore a popular choice for loft conversions. They are also the most cost effective and versatile option. Available in different colours, shapes and sizes, they are easy to tailor to your style and requirements. In addition, you can install them low or high on the wall, meaning they can accommodate the shape and layout of the room.

Internal Water Cooled Units

If you are not allowed to install a traditional air conditioner with an external unit or are limited on space, you can install internal water cooled air conditioning. Unlike traditional air conditioner, water cooled systems do not require an external condenser unit. The internal condenser is installed and hidden in an enclosed space such as a cupboard. This mean that you can install an AC unit that doesn’t impose on the visual aesthetic of your home. These units also do not require any planning permission, making them suitable for any property.
