New HVAC systems whitepaper tackles building sustainability and overheating issues

With the built environment contributing 40% of the UK’s total carbon footprint and the Committee on Climate Change (CCC) warning of the dangers of overheating buildings, a new whitepaper is highlighting the importance of sustainable HVAC systems to construction professionals. The new whitepaper, from polymer specialists REHAU, identifies issues around building overheating, air quality and sustainability, and the need to decarbonise new and existing buildings to meet net zero targets. Citing UK Green Building Council findings that heating and cooling is responsible for large quantities of buildings’ ‘in use’ emissions, it explores the impact of sustainable HVAC systems on construction. Following CCC warnings that not adapting the built environment to changing climates could pose major risks to occupant health from overheating, the whitepaper looks into thermally activated building structures (TABS) technology’s role in resolving this. A means of space heating and cooling, TABS uses pipework embedded within a building’s concrete structure, running either an elevated chilled water temperature for cooling requirements, or low-temperature hot water for the premises’ heating needs. “TABS is growing in popularity because they are economical and efficient, yielding up to a 47% reduction in annual energy costs when compared to traditional HVAC systems,” says Franz Huelle, Head of Technical at REHAU Building Solutions. “This is because whether for heating or cooling requirements, water flows of different temperatures influence the temperature of the building’s concrete structure. “By opting for such a system, specifiers eliminate the need to regulate temperatures in individual rooms with their own specific load requirements. Instead, the pipework allows the building’s mass and thermal dynamic behaviour to be used to maintain comfortable conditions, almost like a living organism.” Commonly used for larger buildings, TABS processes activate the large thermal mass of concrete structures, acting as a buffer for varying cooling or heating loads throughout the day. REHAU’s whitepaper explores the benefits of the technology’s high thermal inertia, large surface areas and radiative heating and cooling properties, including reduced carbon emissions and increased occupier health and comfort. Franz challenges: “When it comes to selecting an appropriate HVAC system, everything always comes down to one fundamental question – does this technology offer a compelling business case? As our new whitepaper identifies, given the pressures to deliver buildings that meet future sustainability needs, TABS should definitely be considered under these parameters. “For example, because these systems can continuously expel heat throughout the day, they are well-placed to tackle the urgent threat of buildings overheating in the warmer months. This is of particular importance as weather patterns become more extreme and high-performance insulation becomes the standard in new-build properties.  “Contractors, specifiers and developers may therefore need to engage more specialist assistance to meet these challenges and other longstanding priorities such as lowering construction and maintenance costs,” concludes Franz. “TABS’ ability to realise these benefits while decarbonising the nation’s building stock explains why building professionals should read this new whitepaper and explore the technology’s viability going forward.” For more information and to download REHAU’s new whitepaper, click here.

Underfloor heating and smart control questions answered

Contractors must be prepared for the growing popularity of smart control technology in residential and commercial building heating systems, according to Warming The Next Generation, a new downloadable guide from polymer specialists REHAU. With space heating methods continuing to change and develop as efficiency and sustainability becomes an increasing priority, REHAU’s new guide focuses on smart controls and their role in this shifting landscape. Specifically, it explores the use of underfloor heating (UFH), and its flexibility in commercial and residential properties when combined with such smart technology. The guide explores trends in modern space heating requirements in multiple environments, including co-working spaces and home offices. It goes on to outline the growth of smart controls within the heating and energy markets and offers practical advice for developers and contractors looking to implement smart control and underfloor heating technology into their projects. “We are moving towards a smart future and the role of technology in our everyday lives is increasing exponentially,” says Franz Huelle, Head of Technical at REHAU Building Solutions. “With guides such as Warming The Next Generation, we aim to raise awareness of this ongoing trend, the factors behind it, and what it means for building professionals. Equipped with clear, concise information about the future of UFH and smart controls, contractors and developers can ensure they are best placed to react to this growing demand for greater levels of modular control within residential and commercial buildings.” Referencing the introduction of 5G and the ever-growing smart technology market, the guide goes on to highlight the importance of keeping abreast of the latest smart innovations as the construction sector moves toward a connected future. Using REHAU’s own NEA Smart 2.0 UFH smart control as an example, it explores how internet connectivity, machine learning and geofencing technology can optimise space heating, simplify installation and maintenance, and give any building heating system flexibility and adaptability long into the future. Franz continues: “Alongside government bodies and contractors, suppliers have a major role to play in ensuring the country’s building stock is sustainable and efficient, and this guide is part of our commitment to achieving this. We want to show construction professionals that, regardless of their project’s size or complexity, expert advice and comprehensive, flexible solutions that improve overall sustainability are available.” For more information and to download Warming the Next Generation, visit: www.rehau.uk/smartguide
