“LEEDership for Sustainability”

“GREEN BUILDING”-Not the conversation of a decade ago

• Accreditations: CHEERS, HERS Rater, Sustainable Building Advisor, CGBP, LEED AP• Members: USGBC Northern California Chapter, Emerging Green Builder, Architecture 2030, BOMA, RESNET

Energy Modeling

Lee Eng Lock – “Almost anything that uses energy needs to be looked at with a new pair of eyes”

People Don’t Want Energy

Hot Showers Cold BeersThey Want:

AB 1103• Assembly Bill

– Requires electric and gas utilities to maintain records of building energy consumption

– Moving the industry toward better building efficiency– California Wide – Existing Stock

• Portfolio Manager– ENERGY STAR Score– Same as LEED EBOM

• 2010 you will see the effect

Who?• Who is modeling for?

Its for EVERYONE on EVERY project whether LEED or

notNumerous studies have shown there are no day lighting or energy

benefits with window-to-wall ratios over 60 percent25 and 40 percent is optimum Yet we continue to build glass boxes

When? - Early

• When just 1% of a project’s up front costs are spent…up to 70% of its life-cycle cost may already be committed.” – Joseph Romm, energy expert

• A couple thousand up front can pay for itself in the first couple months

• Small 4 story Soma building – built 2001– Monthly spending $20,000 on energy

What?• DOE2

– DOE2 1e-Visual DOE– eQuest– EnergyPro– HAP-Carrier– Trace– Energy 10• Weather maker• Energy Plus• TRYNSYS• Green Building Studio– Its not just Title 24 calcs• Studies show the most effective models come from outside 3rd parties –

and rarely from engineering firms

Graphical User Interfaces

• Makes energy modeling easy to use• We used to text edit for DOE Simulations• DOE – working to develop better GUIs
