Thurston Engineering Services is active and involved: in the work we do, in the associations we enlist to, in the community we live, and in the way we live. As such, we have much to share.

National Energy Code for Buildings in Saskatchewan
Posted Jan. 11, 2018

Joining its neighbours Manitoba and Alberta, Saskatchewan has adopted the National Energy Code for Buildings 2015 (NECB 2015), coming into effect on January 1, 2019.


Thurston Engineering Services has been ensuring that Manitoba buildings meet the NECB 2011 for a few years now, serving as energy modellers for the Performance Path and as Coordinating Registered Professionals in stamping the building permit applications for meeting NECB/MECB.  Through this process (especially as experienced energy modellers through the Performance Path), Thurston has helped developers and designers make informed decisions on design and equipment options that best improve the efficiency of their buildings, thereby meeting the province’s intent in adopting this code.


We are happy that our province is striving for the same standard and will see the same benefit, and we can help any team that is treading new (or old) waters with this code.


Daylight Modelling
Posted Jan. 11, 2018

Spend ten minutes in a seminar discussing the real costs of running businesses and designing buildings to suit those businesses, and the profound effect of daylight exposure to productivity will be addressed.  The electricity savings associated with less artificial lighting usage is obvious, but who does not hugely prefer working, or healing (in the case of a hospital), or learning (in the case of a school) in a sunny, well-lit space over one lit with fluorescent or LED lights? On top of that, Saskatchewan, Alberta and Manitoba have the most and the best sunlight in the whole country…why aren’t we using it to our maximum benefit?


One reason is because proper daylight design is hard: while too little daylight is an apparent problem, too much causes glare and discomfort that is real and also to be avoided.  Lots of windows can also mean lots of thermal conductivity and energy loss through the envelope, so a balance has to be sought.


Because of the clear benefits of daylighting, but also the challenges of glare and balancing against energy use, Thurston Engineering Services is pursuing daylight modeling as a natural extension of its energy modeling.  Together, LEED points in EQ Daylight and EA Minimum/Optimize Energy Performance can be optimized.  This is will be even more advantageous as LEED version 4 (LEEDv4) comes online, as it increases the points available with daylight design but also requires either computer simulation or actual measurement (prescriptive path is eliminated).


While energy design/modeling is most effective when done early in design, in reality, an experienced design team can piece together energy efficient components to meet energy goals without extensive early modelling involvement; however, daylight can not be done in the same way.  A daylight consultant is needed to assess the sun’s position and the architectural elements through a series of timesteps to make sure spaces are adequately lit, but not over-lit.  This must be done early in design to get a favourable result, but the outcome of a sunny, beautiful building (that people will want to be in) will make it all worth it.

Manitoba Energy Code for Buildings, Coordinating Registered Professional (MECB-CRP)
Posted Jul. 30, 2015

As a natural extension of our energy modelling for the Manitoba Energy Code for Buildings (MECB) Performance Path option, Thurston Engineering Services can now serve as the Coordinating Registered Professional (CRP), required to issue a stamped MECB Certificate of Compliance to the Manitoban municipality prior to final occupancy.


As energy modellers, we believe we are in the best position of all consultants to provide this: the Modeller is the one that is guaranteed to look at all energy systems (architectural, mechanical and electrical) with respect to MECB requirements.  With this cross-scope knowledge, it is simply a matter of discussing any learned MECB compliance issues with other professionals on record (as would be done with the model anyways), and then confirming that construction is as per consultants' MECB-compliant design.  The added cost is minimal, as was the intention with the adoption of MECB.

As always, Thurston Engineering Services strives to add as much value as possible to the process: we encourage teams to add a Modeller early in the process so that the model can be used to gauge cost effectiveness of design options, rather than just used as a verification tool.  Besides, a great advocate of energy modeling and early energy design discussion, Manitoba Hydro (, will foot all or most of the energy model bill through its design incentives.  Zero cost, lots of benefit.
