Dr. Alan Darlington’s seminar at IIDEX Canada 2016

Don’t miss Dr. Darlington’s last seminar of 2016!

Following his invitation to 2016 Cities Alive (where he participated in an expert panel and received Nedlaw’s Interior Green Wall Award) and his seminar last week at Buildex Calgary, our founder Dr. Alan Darlington is headed to IIDEX soon!sassafraz_26790

In his seminar “How Green are Green Walls”, Dr. Darlington will discuss how the functionality of Nedlaw biofilters surpasses the purely aesthetic role of other ‘green’ walls. His seminar will reveal how biofilters solve indoor air quality, thereby improving occupant well-being and building performance.

Register today!

You’ll learn about the amazing benefits of a Nedlaw living wall biofilter – how it removes indoor air contaminants, the system’s ability to generate virtual outside air for a fraction of the cost of traditional air handling systems, plus an overview of the operating costs and the energy savings, based on recent research.

See you at IIDEX Canada, Booth 4628!


Nedlaw wins Green Wall Award of Excellence

Nedlaw Biofilter wins 2016 Green Roof and Wall Award of Excellence

BRESLAU, ONTARIO – Nedlaw Living Walls, the world’s premier living wall biofilter company, has won the 2016 Green Roof and Wall Award of Excellence from Green Roofs for Healthy Cities ( for the 2,400 square foot biofilter at the Edmonton Federal Building. Dr. Alan Darlington will be receiving the award, in person, at the Cities Alive 14th Annual Green Roof & Wall Conference on November 3rd, in Washington D.C.

Nedlaw Living Walls designed and built the living wall for the new Edmonton Federal Building lobby, under the direction of architectural firm, Kasian. As an architectural landmark and one of Canada’s best examples of art deco style, the Federal building recently underwent an extensive revitalization project. According to Esther Rivard-Sirois, Architect AAA, MRAIC, LEED AP BD+C, MArch, GRP, Project Architect & Sustainability Lead at Kasian, “The green wall at the Edmonton Federal Building is a great addition to the public space. It heightens the senses and brings life to the pavilion. It complements the architectural tree-like wooden beams in the pavilion and creates a warm and inviting natural environment all year long.”


The two-storey living wall biofilter covers multiple sides and incorporates a water feature making it the defining focal point in the newly added lobby area. At 2,400 square feet, this is the largest known indoor air biofilter and it provides much more than an aesthetic feature. The biofilter is a working element of the building’s mechanical system. The wall draws in dirty air, removes pollutants and returns clean air to the space, thus improving air quality. According to Dr. Alan Darlington (the technology’s founder), “This biofilter actively removes pollutants from the air, generating over 1,500 cfm (700 litres per second) of virtual fresh air. That’s enough ‘fresh’ air to supply two thirds of the needs of over 150 people. And this virtual fresh air is generated using up to 90% less energy than conventional air treatment systems”.

By supplying clean air at a fraction of the cost of traditional HVAC systems, this biofilter lowers energy costs to improve building performance. The living wall also contributes to the humidity levels of the atrium space. As such, the living wall system adds points to the LEED Gold certification goal.


Nedlaw at Cities Alive Conference in Nashville

Water the Key to Everything Green
Water is fundamental to life and to green infrastructure. At the 12th CitiesAlive® Green Roof and Wall Conference in Nashville, delegates will explore the many ways in which green roofs and walls can help manage our water resources more wisely. Participants will dig into the science of performance, explore the many interrelationships between energy and water, and investigate the most forward thinking designs and policies that fuel essential innovation in green building and infrastructure.

Presentations by Alan Darlington:

  1.        Water Usage in Circulating Irrigation Systems

Water is too valuable a resource to flush down the drain. How exactly do green roofs manage and control water? And how do they fail to do so?


  1.        VOC Removal by Living Wall Biofilters

Biofilters remove a wide range of air pollutants and significantly improve indoor air quality
