Dear SimClub Member,

The IBPSA-USA Denver Chapter would like to remind everyone that our next
virtual event is taking place *NEXT WEEK* on *Thursday, October 29 from 6 -
8 PM Mountain time*! We hope that you can join us.
Portfolio Energy Optimization – A Simulation-Based, Scalable Approach to
Evaluating Zero Carbon Commercial Building Retrofits

Buildings emit about 14 Gt of greenhouse gases every year making them one
of the largest contributors to global carbon emissions. 75% of these
emissions from buildings are a result of operating them. It is also
estimated that two-thirds of buildings that exist today will still be
operational in 2050. Hence, retrofitting existing buildings to reduce their
operational carbon emissions is one of the most effective ways to reduce
global emissions and this can be rapidly scaled by applying these
strategies to large scale portfolios. However, cost is still a barrier for
large scale portfolio owners to undertake energy performance studies
involving building-specific or measure-specific analysis.

RMI’s Portfolio Energy Optimization (PEO) initiative aims to address this
issue in a disruptive and scalable way. PEO integrates deep financial and
energy efficiency studies using a mass-customized approach to significantly
reduce the cost for analytics. The engineering analysis is translated to
the language of “investors” to enable decision making by also incorporating
financial analysis and GHG emissions assessment.

The first half of this presentation will focus on the overall framework of
the PEO tool. PEO tool leverages the Modelkit framework developed by Big
Ladder team to automate the generation of template energy models. PEO’s
workflow involves automating the most tedious parts of energy model
generation such as geometry creation, thermal zoning, schedules generation,
etc. using parameterized inputs. The workflow also integrates energy
modeling results to first costs associated with a database of energy saving
measures with a capability of automated optimization and bundling of

The second half of the presentation will go over the case study of Canada
National Capital Region portfolio where 162 buildings were analyzed using
PEO’s framework to outline a pathway to reduce carbon emissions by 74%.
This corresponds to 45% savings related to energy savings and 26% reduction
in terms of energy cost.
