RRCL was recently reviewing a conventional two-ply mod-bit roof and observed all these blisters! Happy that Property Management are not reporting leaks, however, this is not what you want to see on your roof. Why do YOU think this is happening? Contact RRCL if you want to know the likely answer…!
…better known and a fun day in south western Ontario! Our testing team completed a 12 fan whole building operational test at this 230 unit (30,000 m2) apartment building. Testing went smoothly and the building performed quite well, given the fact that each apartment has a ventilation penetration.
Are you designing a new building? Are you striving for passive house certification? The implications of shading, whether from surrounding buildings or surrounding natural elements, really matters!
Contact RRCL to conduct whole building energy performance simulation and we can show you how shading integrates with energy use, comfort, etc. And yes … we can certify to the PHIUS+ passive house standard.
This building…one fan (well, less than one fan, actually!) Are you surprised? We were NOT! We’ve tested several large Passive House buildings such as this one and are planning many more. Contact RRCL for all your big building airtightness needs – leaky or tight – we have the capability to execute a successful test.
Last month we took apart two Ultimate Air RecoupAerator 200DX whole house ERV units that required specific maintenance; one a new motor, the other new bearings. When taking these apart, we were reminded how elegant a design the units were. We were also reminded how dirty they get after 5+ years of use! In case you are wondering, yes, we successfully repaired both units and they have been running smoothly.
RRCL has expertise in mechanical ventilating devices – balancing, commissioning and maintenance. Contact firstname.lastname@example.org for more information.
We were recently assessing the building envelope of an office building in downtown Ottawa. As we climbed up the roof ladder and surveyed our surroundings (our normal procedure when going on roofs), I noticed this special view.
Contact RRCL to conduct building envelope and roofing assessments. Whether you need long-term repair and maintenance forecasting, or an immediate water penetration investigation, RRCL is an industry leader in enclosure performance and forensics.
RRCL, in partnership with Coefficient Building Science, is leading the industry in big building air-tightness testing. Whether you need a whole building test, guarded floor or guarder suite, contact RRCL or Coefficient and we will support your project needs.
RRCL recently delivered a two-day WUFI workshop to a building science group within a large Ontario consulting engineering firm. Here’s what they had to say:
“A group from our building science team recently completed a two-day WUFI training with Russell. We all had different levels of knowledge and experience using the software. Russell successfully managed to cover all the basics of the software and expand on the modelling, analysis, and delivery of results. The training was very engaging and focused on our needs. We were able to work on various case studies, with refences to real projects, gaining practical knowledge and experience with the software. The benefits of having a customized training course was invaluable. We could ask questions and resolve issues that were specific to our projects and field of work. It was an extremely effective course and we left with a lot of practical and useful information. Russell is an excellent instructor with real passion for building science.”

Here is an incredible example of metal cladding corrosion at one of our projects visited in late June 2020. Wasted from an industrial process was stored for long periods below this area. Corrosive gasses accumulated at the top of the warehouse building and caused the deterioration to the metal cladding.
