‘Sustainability in HVAC imperative’

RWIRubber World Industries (RWI), a major provider of rubber insulation products in the GCC, is taking steps to promote sustainability through its HVAC products

With summer temperature reaching as high as 50ºC, HVAC systems are a necessity in the Middle East region. In a statement released recently, RWI said that it remains committed to promoting a ‘greener’ world by integrating net zero energy and high-performance systems in its projects.

It is undeniable that HVAC systems have changed the way buildings are designed, built and occupied. The evolution of electronics in equipment has made HVAC systems smarter, smaller and more efficient. They have also reshaped how the systems are installed, how they are maintained, and how they operate.

But a pressing concern about HVAC systems is about how they can contribute to sustainability without sacrificing energy efficiency.

With this in mind, the GCC governments have pushed the sustainability aspect in HVAC systems by introducing new regulations and enforcing the standard codes.

Net zero energy means that a building balances its energy needs with energy produced from renewable and zero-emission sources. This involves improving control of electricity, reducing the consumption and contributing towards supplying high-quality energy. One of the ways to achieve this is to minimise the load of the building envelope which affects what is called as space conditioning.

Space conditioning consists of heating, cooling, and introduction of outdoor air and is considered to be the largest energy consumption in a building. It is a system responsible for the heat loss and gain through the building envelope, the unwanted infiltration of outside air and the buildup of contaminants within the building. To minimise the energy consumption, it requires an evaluation of the insulating capabilities as well as controlled flows of fresh air across the building envelope. Along the process, building loads are reduced. After the load reduction in the building envelope, the next step towards net zero energy buildings is through the use of efficient equipment, which focuses on space heating and space cooling.

Factors to be considered here are the design and installation of vapour compression heat pump systems for energy-efficient buildings and the effectiveness of low global-warming potential alternatives for hydrofluorocarbon refrigerants.

Engineers too have a pivotal role to play in achieving energy-efficiency. They look into the preventive procedures to reduce chances of premature equipment failures, provide for periodic inspection building systems in order to avoid energy emergency breakdown, and describe overall responsibility for the operation, maintenance, repair, and replacement at the project level.

But fulfiling the demands of mixed-use facility can be challenging, considering the structure’s diverse components. RWI has a solution for this, and that is to engage the facilities team in the selection process to ensure that the components are using the system control.

Other than our HVAC products which meet global standards, one of its keys to success in this industry is the support system in terms of service to the customers. According to RWI, this is a proven track record.

RWI also resolves system integration challenges by guiding the clients what type of insulation system is needed to be installed.
