Using Natural Light to Reduce CO2 Emissions

How choosing the right window and door systems can impact your energy usage

Natural light has long since been regarded as an essential rather than a luxury within any new build home project. In modern architecture, large elevations of oversized glazing are regarded as the ultimate luxury and interior design schemes often revolve around spaces flooded with natural light.

Building regulations part L1A sets out guidance for balancing solar gain with the amount of daylight that will need to be supplemented with electric lighting. Highly glazed spaces run the risk of overheating if this is not taken into consideration during the early stages of a project. There are many proven ways in which IQ can eliminate the risk of your glazed spaces overheating, including utilizing our solar control glass technology.

Building Regulations recommend “an appropriate combination of window size and orientation, solar protection through shading and other solar control measures, ventilation and high thermal capacity.”.

It is beneficial for architects to include glazing sensibly within new builds, to utilise natural light and ultimately limit the use of artificial lighting. All of our window and door solutions are fully thermally broken and deliver exceptional levels of thermal performance. When specifying the full glazing package, a mix of opening and fixed elements can be discussed with the technical experts to ensure the space is adequately ventilated.

As the first fully thermally broken structural glazing system, the Invisio system delivers high thermal performances to keep highly glazed spaces comfortable in the colder months, whilst preventing overheating in the summer.

Part L1A states that “As a general guide, if the area of glazing is much less than 20% of the total floor area, some parts of the dwelling may experience poor levels of daylight, resulting in increased use of electric lighting.”. It is beneficial for architects to incorporate as much natural light into the project as possible, particularly in projects striving to follow a biophilic architectural design.

The sun’s rays can cause discolouration and damage to furniture if precautions aren’t taken to provide solar shading. Specifying low e glass will enhance the functionality of the design, whilst prolonging the life of your furniture.

Solar control glass is an invisible solution that works by reducing the amount of short-wave radiation that travels through the glass units, therefore reducing the overall heat levels inside. If a softer approach is preferred, integrated curtains can be specified. With concealed tracks and hidden fixing details, recessed curtain tracks are the perfect choice for soft, minimal designs.

Whichever window and door systems are specified for your project, IQ are on hand to help advise on glazing specification, opening elements and any other specific requirements. Just get in touch to see how you can utilise our advanced glazing systems to cut down your CO2 emissions.
