Specifying window shutters to comply with Part O regulations

1. The key details around Part O

   The main aim of Part O is to limit overheating by reducing the level of solar gain entering buildings.  Done effectively this will reduce reliance on air conditioning systems, thus reducing the carbon footprint of the building by reducing CO2 emissions.

   Introduced in June 2022, Part O stresses that “The building should be constructed to meet [the] requirement using passive means as far as reasonably practicable… Any mechanical cooling (air-conditioning) is expected to be used only where [the] requirement cannot be met.”

2. About Window Shutters

   Part O regulations identify shutters in sections 1.9 and 2.7, as “acceptable strategies for reducing overheating risk.”

   The benefits of using window shutters?

   

   Being installed on the external façade means Shutters are a much more efficient way of reducing solar gain.

   Unlike fabric blinds, metal shutters provide a significantly more robust solution especially in areas susceptible to high winds or weather extremes.

   They work by preventing heat gain during extreme summer temperatures, or allowing sunlight in during colder months, meaning when it is a colder day the sunlight can naturally warm the space.

   By regulating the amount of heat entering the building, means your building is less reliant on air conditioning unit and central heating, saving on bills and reducing the carbon footprint of the building, meaning your project is not only more environmentally friendly but more energy efficient and will help to reduce running costs..

3. What challenges does this pose to specifiers

   As architects and contractors you bear the responsibility for ensuring this regulation is incorporated into your design, but it can, and often is, difficult to manage creativity with compliance, especially in the eye of the customer.

   

   Using window shutters to meet Part O regulations requires some consideration at the planning stages, but nothing that can’t be overcome.

   Aesthetically external shading such as shutters, louvres and blinds are commonplace across Europe, but less commonplace here in the UK.  So explaining the key benefits to the customer is essential to successfully incorporating shutters into your design.

   From an installation perspective fixing details and wiring need careful consideration, but with our team of experts are on hand to work with you to explain the nuances and provide solutions to suit your project.

4. Consideration for Specifiers

   When looking at which products to specify around Part O there are a number of areas to consider.

   Visual Appeal:

   You need to think about whether you are after maximum performance, or visual appeal.  Window shutters provide a much higher level of performance over fabric blinds, but provide a slightly harsher look.

   How to Fix

   Window shutters can be face fixed or recessed, with the latter requiring a lot more thought and planning.  A recessed shutter gives a cleaner look but can lead to problems around servicing or maintenance.  A face fixed shutter can be designed to complement the façade of the building.

   It is always recommended to consult with an industry expert, such as one of our installers or surveyors when specifying window shutter for your projects.

   Security Benefits:

   An additional thing to consider are the further benefits shading solutions provide, such as the added security of window shutters, which not only shade the internal building, but provide accredited security elements to improve building safety.
