DesignBuilder Team Wins ASHRAE Energy Modelling Conference's 'Best
Innovative Workflow' Award

DesignBuilder's advanced cost-benefit analysis tools enabled the team to
produce a cost-optimal net-zero energy building in a fraction of the normal

Santa Rosa, CA - October 23, 2015 - Team DesignBuilder was thrilled to be
announced winners of the Lowdown Showdown competition's "Best Innovative
Workflow" category at the recent ASHRAE Energy Modeling Conference.

The competition was designed to showcase the work of teams pushing the
boundaries of mainstream modelling software tools to create a net zero
energy (or below) building. ASHRAE's requirement was to design a 53,600 sq.
ft. 3-storey office building with a number of constraints, but left other
criteria such as the building location, form, fabric and HVAC systems open
to stimulate creativity and innovation.

Cost is an important part of most projects so the team was keen to test
DesignBuilder's optimization capability and decided on a 3-step advanced
cost-benefit analysis approach. DesignBuilder Optimization uses a genetic
algorithm which mimics the "survival of the fittest" principle of natural
evolution to efficiently identify the best combination of design variables
(such as orientation, insulation, glazing, lighting, HVAC). This makes it
possible to find optimum solutions much more quickly than traditional
methods, providing the design team and client with an added level of
confidence that all viable solutions have been identified. Using
DesignBuilder Optimization, which is unique among mainstream software tools,
enabled the team to identify the optimum net-zero solution and also to
quantify the cost-benefit of higher and lower performing solutions.

"Given the team's desire to use this innovative cost-benefit approach to
modelling, we were all delighted to win this particular award for
innovation," said Dave Cocking, one of the DesignBuilder coaches. "This was
a great opportunity for us to work with some very talented and enthusiastic
team members and gave us all the opportunity to present something
cutting-edge and a little different at the conference. It is fantastic that
the team's effort resulted in this accolade from the voting ASHRAE
