By focusing on energy efficiency, avoiding energy wastage and considering and measuring embodied energy, designers can successfully reduce carbon in buildings
Sizing in general is an important factor when it comes to heat recovery – over specification of a unit wastes energy. Specifiers should choose a heat recovery unit which meets the necessary airflow requirements. There are free cloud-based tools available that allow specifiers to select fans to exact duty points so the fan will operate in a building as designed.
Embodied energy
As energy efficiency reaches greater heights, there is greater focus on the embodied energy of products in our buildings. To reduce embodied, energy specifiers should look for products that are UK- manufactured, with the supply chain involved as short as possible. Also opting for a product that is completely serviceable and maintainable so each component can be removed and replaced if necessary, is very helpful in extending the life of a heat recovery unit. It is also important to consider the end of life of a product ensuring it can be easily re-purposed or recycled. When designing a building to be low carbon or carbon neutral, there are many challenges to consider, from selecting materials to co-ordinating multiple layers
UltraCare products join Mapei Zero Line
Seven treatments from the UltraCare range have joined Mapei UK’s Zero Line – a range of low environmental impact products. They include six UltraCare surface maintenance products and UltraCare Smooth Silicone. The extended portfolio, which also includes installation and building products, provides safe and sustainable high-performance solutions with CO2
emissions – measured throughout the life cycle of products from the Zero line in 2023 using Life Cycle Assessment (LCA) methodology, verifi ed and certifi ed with EPDs – have been offset through the acquisition of certifi ed carbon credits in support of renewable energy and forestry protection projects. The portfolio demonstrates Mapei’s commitment to the planet, to people and to biodiversity. Mapei’s UltraCare series provides a solution from installation, to the protection and maintenance of surfaces in private and commercial settings. Treatments are formulated for all types of natural and engineered stone and tile fi nishes and are tailored to a tile’s fi nish and individual characteristics.

Tiling_DPR.indd 1 Parkside goes on protecting with 40 for 40
To date, 40 for 40, a partnership between Parkside Architectural Tiles and World Land Trust has protected over 156 acres of biodiverse habitat. 40 for 40 is a partnership between specifi ers, Parkside Architectural Tiles and the World Land Trust,
www.worldlandtrust.org, to protect the world’s precious natural habitats. By specifying tiles from Parkside that have 40% recycled content or above, specifi ers can play an active role in saving land and species. In its most successful quarterly period to date and since June alone, 40 for 40 has stepped up for 36 acres of permanently protected nature reserves in Argentina, Brazil, Kenya and South Africa. Jonathan Wiles, director of commercial sales, Parkside Architectural Tiles, says: “40 for 40 is part of a measured approach to reducing our impact on the planet. The scheme commits to land purchase on every square metre of tiles from Parkside that are specifi ed with 40% or more recycled content. We’re delighted to be contributing to the work of the World Land Trust in 40 for 40 which we see as a balanced approach that not only considers resources, but also goes someway to give back to nature.”

of supply chain management. Obtaining accurate and up-to-date embodied carbon information is crucial for ensuring that the building meets its carbon reduction targets. However, this can be a time-consuming and complex process, as it requires data to be collected from multiple sources, including suppliers, manufacturers and contractors. Manufacturers are therefore now taking additional steps to provide the embodied carbon information that designers need such as by using CIBSE TM65 data collection methodology to collect accurate and detailed embodied carbon information. Working from a component level, this methodology ensures that data are comprehensive, and up-to-date. So, when building designers are considering how to ventilate a low carbon or carbon neutral building, heat recovery ventilation is a good solution. By focusing on energy efficiency, avoiding energy wastage and considering and measuring embodied energy, designers can successfully reduce carbon in buildings as we head towards net zero 2050.
