The need to completely decarbonise the built environment by 2050 is evident. The built environment generates 39% of annual global CO2 emissions. The day-to-day operation of our buildings is responsible for 27% of these emissions, while the materials and construction practices make up the remaining 13%.[1] To limit global warming to a maximum 1.5^oC, 100% of buildings must operate at Net Zero carbon by 2050, with all new buildings operating at Net Zero carbon by 2030[2] - just seven years away. So how can this be achieved?

To begin with, there needs to be a clear understanding of what it means to decarbonise new buildings. Firstly, the materials used to construct the building must have net zero embodied carbon. Secondly, the house must be net zero operational carbon once it’s built. And thirdly, the house design must incorporate circular economy principles.

In County Wexford, southeast Ireland, work is already underway on Project Net Zero Home near MEDITE SMARTPLY’s wood-panel manufacturing facilities. This exemplar new-build house aims to demonstrate how to put the above theory into practice, with the aim of achieving Net Zero Carbon.

Using Net Zero Carbon design principles, the home will be extremely energy efficient, built using advanced timber frame construction and high-performance engineered wood products from MEDITE SMARTPLY and will employ a Whole Life Carbon methodology that will provide a true picture of the home’s impact on the environment over its entire lifetime. This includes its reuse, demolition and disposal.

As there is currently no Building Regulation requirement to measure embodied carbon or make any attempt to reduce carbon emissions from building materials or construction processes, buildings can easily achieve ‘operational net zero’ but built with materials that are not environmentally friendly. Project Net Zero Home aims to replace as many carbon-intensive materials with low-carbon alternatives (such as wood) as possible, to minimise the embodied carbon emissions of the building.

MEDITE SMARTPLY products will play an important role in achieving Net Zero. Speciality SMARTPLY OSB and MEDITE MDF products, along with other low carbon building products will ensure that the home meets the highest standards of energy efficiency and sustainability. SMARTPLY products include AIRTIGHT for the walls and ceilings, and ULTIMA for the flat roof and garage. MEDITE products include MEDITE TRICOYA EXTREME for the kitchen kicker boards, integrated dishwasher door and insulated front door, and VENT for the walls, flat roof and garage.
