Overview 1. The Rise of BIM 2. UK Government + BIM 3. UK Green BIM 4. Architype Green BIM
1. The Rise of BIM
BIM isn’t new!
Why now? 1. Software & Hardware capabilities 3d Modeling Structured Information Digital Collaboration
Why now? 2. Digital / Social Media ‘Tsunami’ Digital everything Social everything … will the construction industry catch up?
2. UK Gov + BIM
EU Directive Energy Performance of Buildings Buildings consume 40% of energy in EU By 2018 All new public buildings “Nearly Zero-Energy” By 2020 All new buildings “Nearly Zero-Energy”
UK Gov Strategy
UK Gov Strategy
UK Gov Purpose 20% reduction in capital costs 20% reduction in CO2 emissions + reliable outcomes + predictable building (asset) performance
UK Gov BIM “Building Information Modeling (BIM) is the process of generating and managing information about a built asset over its whole life.” Cabinet Ofﬁce 2012
UK Gov BIM + GSL
3. UK Green BIM Aspirations & Reality
Aspirations EPDs linked to Models Model based Green Rating compliance check The RegBIM project using IFC underway
Reality … ? Model based Embodied Carbon + Lifecycle Analysis Impact speciﬁcation / database www.impactwba.com
Reality … ? Model linked Responsible Sourcing / Environmental Impact data NBS Create speciﬁcation tool using Uniclass2 constructioncode.blogspot.co.uk
Reality REM - Rapid Energy Modeling Energy Carbon Day lighting Water Wind Thermal comfort Renewable energy generation Caveats Conceptual design guidance only Not an accurate prediction of actual performance
REM example 1 autodeskvasari.com
REM example 2 www.sefaira.com
Reality Dynamic Simulation Modeling Thermal modeling Overheating “Conservation of Fuel” regulations compliance Caveats Often not an accurate prediction of actual performance Interoperability issues often require re-modeling
Reality Material waste reduction Accurate quantities from model Buildability issues resolved in model Caveats Is the model built for this purpose? How accurate? How resolved?
Reality Scan-to-BIM for Refurbishment ~80% of building stock exists already Accurate existing building model Early analysis of cost & carbon effective measures Risk / Cost reduction
Reality In-Use Energy / CO2 emission reductions Accurate design data Accurate energy modeling tools Greatest climate change impact for new build Robust long term performance Signiﬁcant cost savings / Best ROI Healthier buildings
4. Architype Green BIM
Passivhaus Standard “…the world’s leading standard in energy efﬁcient design” Rigorous performance standard Quality assurance Optimal comfort (ISO 7730) Minimal energy Climate speciﬁc – works anywhere
PHPP “simpliﬁed models, precise data” Accurate Open Parametric Instant
Data 4 QA Passivhaus can be seen as a quality assurance standard that ensure that the right information is used at the right point in the process to deliver reliable robust energy performance & comfort.
BIM + Passivhaus Process + Information + Model and test - Not box ticking - Not sexy graphics - Not on site
BIM 4 Passivhaus Simple + Useful + Productive 1. Visual interrogation 2. Accurate Live Numerical Data
Visual Interrogation Design coordination / integration Thermal Continuity Heat Loss Envelope
Heat Loss Envelope
Accurate Live Data Treated Floor Area (TFA) Actual Volumes Ventilation Volumes Heat Loss Areas Window / Door Opening Areas
Areas and Volumes
Heat Loss Areas
Outcomes 2 x 65kW Boilers for a 2200m2 School 25kW peak heat demand = 5x oversized! 90% reduction in gas consumption
Fresh Indoor Air
Client Satisfaction “We feel that our children are more alert and attentive in lessons due to the amount of daylight in classrooms and the fresh air throughout the school ... learning has been enhanced” Sara Morris, Head Teacher
