Carbon Zero Building & HVAC

building’s carbon footprint is defined as the amount of CO2 it produces during its operations and activities. Considering a building’s carbon footprint is something that is important for both new construction as well as renovating HVAC in existing buildings.

The NZEB standard applies to all new buildings occupied after the 31st December 2020. The definition for Nearly Zero Energy Buildings in the Energy performance in Buildings Directive (EPBD) is “a very high energy performance, as determined in accordance with Annex 1, The nearly zero or very low amount of energy required should be covered to a very significant extent by energy from renewable sources, including energy from renewable sources produced on-site or nearby”.



Keane Environmental work with suppliers who take the impact of their products on the environmental very seriously. They currently provide some of the most energy efficient products on the market and continuously strive to improve even more in terms of product efficiency and minimising carbon footprint.

The installation of the right products during construction or a renovation can help to
significantly reduce a building’s level of energy consumption and CO2 emissions.

Zero Carbon  – Product Life Cycle

Zero Carbon can be as much about what you do with the product after what is perceived to be its useful life,
as it is about how energy efficient it is during its lifetime!

Diffusion Fancoils

With Diffusion fan coil units you get the benefit of the best sfp’s (specific fan powers) on the market.

Diffusions ultra low sfp’s are the result of long term co-operation between Diffusion and the German fan manufacturers EBM. This has led to the development of a range of fans specifically designed to match to the requirements of each size of fan coil unit and resulting in the lowest possible electrical energy used (watts) for each litre/second of air generated.

Furthermore, while most fan coils on the market have a lifespan of 15 – 20 years, with Diffusion it has always been their philosophy that there is no need to replace any of their FCUs. We are presently engaged with updating fans and coils on units that are over 20 and even 30 years old, upgrading them with the most efficient fans and coils that today’s technology can provide.

In the meantime, the client benefits from the true flexibility in control and comfort levels that only a fan coil units can provide.

Gilberts Grilles & Natural Ventilation

Gilberts can also help designers with the carbon footprint of the building they are working on. They have a wealth of experience and knowhow in the whole area of Natural Ventilation, air movement and occupancy comfort levels. Gilberts have been involved in the supply of several ‘Carbon Neutral’ or ‘Zero Carbon’ projects in recent times. They are available to assist and share their knowledge whenever required.

Gilberts also approach Zero Carbon in their own products very seriously. They audit every aspect of their own manufacturing process, i.e. Type of material, sourcing of materials,  the manufacturing process and use of sustainable energy to help establish the carbon footprint of the products. This enables them to constantly review their whole process and come up with new ways of further reducing their carbon footprint. Thankfully most of Gilberts raw materials are made up of Aluminium and Steel, both of which are highly if not 100% recycleable.

Damvent Hybrid AHU

Uses integrated Heat Pump technology in the most efficient way possible, as part of the heat recovery process, and achieving system COP’s previously unheard of.

Enerblue Heat Pumps

Heating, air conditioning and efficient DHW hot water production from sustainable, renewable energy using natural and low GWP refrigerant gases ensures minimum environmental impact with maximum efficiency.

Terrendis Hyper-Flexible Pre-Insulated Pipe.

Terrendis pipes are primarily intended for the transport of heating water, sanitary hot water, potable water, cooling water, waste water or other fluids, in underground distribution networks.  They are ideal for transporting hot water generated by renewable energy powered heat sources such as heat pumps and pellet boilers etc.
