Building sciences

CIS has the developed through experience, the scientific knowledge and expertise to evaluate the indoor environment.  An understanding of building sciences provides our clients with detailed assessments of the indoor environment tailored to their specific needs.  As the function of a building may play a role on the indoor environment, we can identify and assess conditions that affect indoor environmental quality.  We can also provide information and assessments of designated substances and hazardous materials to asbestos management plans, indoor air quality assessment, radon testing, microbial and bacteria investigations.


The building science of a project refers to strategies implemented  in the general and specific arrangement of building materials and component-assemblies.


The practical outcome of building science knowledge is reflected in the design of the architectural details of the building enclosure (see building envelope), and ultimately in the long-term performance of the building's 'skin'. The scope can be, and is, much wider than this on most projects; after all, engineering is applied science mixed with experience and judgment. When architects talk of "building science", they usually mean the 'science' issues that traditional engineering disciplines traditionally avoided, albeit there are emerging disciplines of 'building scientists', 'envelope consultants', and 'building engineers'.

What we do

The research

Indoor environmental quality (IEQ) refers to the quality of a building’s environment in relation to the health and wellbeing of those who occupy space within it. IEQ is determined by many factors, including lighting, air quality, and damp conditions. Workers are often concerned that they have symptoms or health conditions from exposures to contaminants in the buildings where they work.


One reason for this concern is that their symptoms often get better when they are not in the building. While research has shown that some respiratory symptoms and illnesses can be associated with damp buildings, it is still unclear what measurements of indoor contaminants show that workers are at risk for disease.


In most instances where a worker and his or her physician suspect that the building environment is causing a specific health condition, the information available from medical tests and tests of the environment is not sufficient to establish which contaminants are responsible. Despite uncertainty about what to measure and how to interpret what is measured, research shows that building-related symptoms are associated with building characteristics, including dampness, cleanliness, and ventilation characteristics.

Often clients waste a lot of money testing  the air first with out considering the building science aspect. That's why Cis always first examines the structure of the building to rule out any obvious building and structurally related issues.


We are not afraid to get our hands dirty and put on the hard hat. Our team is fully prepared for any and all situations. We go where ever the investigation takes us and  not anywhere else.


Peoples lives are on the line, therefore its our mandate to thoroughly and sincerely investigate and inspect every building we encounter with the utmost attention to detail.


This way the diagnosis  is quicker,  more accurate and  cost effective for most business's and  organizations.

Often times when dealing with indoor environmental issues, the building of the client is not factored into the equation. This typically is the scenario with many new or relatively new constructed buildings, as they are considered to be with out defect or deterioration. This is a mistake. The reality is that no two buildings are  the same. There are a hundreds of various unique factors that can compromise a buildings structure.


Such as climate, temperature, season, materials, builder, etc can all effect the structure, very early on in the building stage. Your indoor air quality issues may just begin right from pouring the foundation.


So when  you are getting your air testing, make sure you get that

beautiful structure thoroughly examined as well. Canadian Invironmental Services can help you with a proper building inspection and let the data find your indoor air quality issues.

Your building may be a work of art, but it also could be the culprit.


Our world is changing day by day as environmental issues continue to impact the planet. As a result our society has an ever increasing need to find more and more sustainable ways of living. This sustainability involves examining our consumption and production of excessive goods and services. Included in this consumption is the availability of the materials we use to build our schools, banks, homes etc.


The challenges are many, and  cutting corners is not an option anymore, as was in the past. As builders used harmful and cheap materials to maximize gain and afford-ability.


Going forward, a balance between afford-ability and sustainability has to be found,. This is crucial for the entire planet as less harmful material are put into production, the less pollution will be created. Indoor Air quality is heavily effected by outdoor air quality, everyone has to their part.


CIS is doing its part by educating clients looking to build or remodel their buildings. Making sure, they aren't choosing any materials which will effect their own personal indoor air quality, and also not to contribute to the global problem.
