[Bldg-sim] 90.1-2010 ECB and PRM questions

[Jones, Christopher via Bldg-sim]

Hello Sim Folks,
I have two questions regarding 90.1-2010 ECB and PRM. Our building code references ECB and LEED references App. G PRM.

Shading due to adjacent buildings – should this shading be modeled for:
ECB –
PRM –

90.1-2010 ECB doesn’t directly refer to shading by other buildings.
App. G as detailed in the PNNL PRM Manual states that external shading from other buildings or other objects can be modeled for 90.1-2010 PRM.

Therefore, I believe one can choose to model that shading or one can ignore it.


Daylighting controls – should daylighting controls be modeled for:
ECB –
PRM –

Re. Daylighting:
Reviewing Section 11.1.4 Compliance with Section 11 will be achieved if:

a.       All requirements of Sections 5.4, 6.4, 7.4, 8.4, 9.4, and 10.4 are met;

Table 11.3.1, 6. Lighting, Baseline: Lighting controls shall be the minimum required.

These clauses lead me to believe that daylighting controls should be modeled in the baseline using the correct side-lighted and top-lighted area calculations.

App. G as detailed in the PNNL PRM Manual is clear – daylighting controls are to be modeled in the baseline.

Any and all thoughts appreciated.

Ohh wow Mayank.

This is really great. Thanks for sharing.
Does anybody have any more such resources.Please share.

Hello everyone,

I have been searching for some books on basics of building physics, and energy simulation and found a very nice resource to understand the building physics along with energy simulation.

Hope this will help to new members in the field of energy modelling and simulation. The book is available at:

https://www.amazon.com/Building-Energy-Simulation-Workbook-DesignBuilderTM/dp/1498744516/ref=sr_1_1?ie=UTF8&qid=1498012115&sr=8-1&keywords=energy+simulation
