The Team of Net ZeroPhilip Macey, AIA, National Director Collaboration


2/19

What to expect We wont show you pictures of

solutions Only one picture of the Research

Support Facility (RSF)

We wont talk about LEED

Learn why the team matters first Learn how to re-sequence design to

create your Net Zero Building


3/19

Conventional Construction Assumes all buildings roughly equal in complexity and technical c

Assumes that the team will self organize and do that multiple tim

Design, Construction and Ownership are separated and segregat

The players are motivated to perfect their area of expertise

True / Total Costs identified late especially energy


4/19

Construction

Productivity near flat

Procurement:Competitive Rather ThanCollaborative Teams

Lack of integration of

design and construction,and often poorcollaboration amongteam members

The Ugly TruthPaul Teicholz Prof. Civil and Environmental Engineering Stanford Univ.

The Four Big Challenges

Every project is a unique assembly offunctions and PLAYERS

Ill make my part the best I can

Technology never sleeps

New people, new knowledge, repeat

Missed schedules, Busted budgets, NZE too costly


8/19

The Foundation In construction are we really building:

Finding and solving concerns of clients,

design teams, construction teams

Focus: Whole project - full, final, in place

Behavior: Transparent, Immediate, Complete

Align Values to Create Trust

Trust


9/19

Cognitive Empathy the ability to understandanother persons perspective

Emotional Empathy the ability to feel whatsomeone else feels

Empathetic Concern the ability to sense whatanother person needs from you

EmpathyFocus: The Hidden Driver of Excellence Daniel Goleman

11/19

Collaboration LooksDifferent 3 levels of leadership include client

whenever possible

Executive Team resources, resolve bigissues

PM Team and Roundtable primary day today control

Functional Groups ownbudget/contingency


12/19

Integrate the SilosCollaborative Project Delivery

optimize the whole building AND the deliveryprocess

Operate Design and Pre-Construction in parallel

Operate CA and Construction in parallel

Integrate the Owners Teams throughout

Change in behavior:Whole Project Thinking,

Onboarding multiple times


13/19

The big 5 Trade Partners - select early energy

+ cost control

Structure primary vertical & horizontal

Mechanical/Plumbing AHUs, Hydronic,

pumps

Electrical lighting, power, controls Envelope opaque exterior materials

Glass Hi $/SF, big energy impact

Constructing Zero Energy7of cos


14/19

The Team of Net Zero

Today Land Net Zero LandProgram + Energy Form + Sy

Cost

Energy Form with Systems o

Program + Form + Systems= Cost..later, Energy

Team Change Move dollars from MEP into Envelope

Architecture and Mechanical start same time

Program space and energy use together, concept level

Create a Black Box energy model in parallel with Form

Create parallel conceptual cost studies


15/19


Today Land Net Zero Land

The Roof is Room (fo

No equipment, limit s

The Roof is a Closet

Hide systems there

Team Change Arch and Mech manage systems: keep rooTeam Change Arch and M and E integrate roof access, con

elect room for interverter in base design


16/19



Managing energy tr

New Role for Envelo

Resisting nature is the ideaR value is king

Team Change Free energy is good, find it, and use it wise

Architecture designs for optimum wall = free energy int

Mechanical designs for maximum free energy use


17/19



The right amount ofglass makes great da

More glass is great, meansgreat daylight

Team Change building skin is daylight membrane Architecture transparency and opacity, both important

Energy and Daylight models are essential for Net Zero


18/19

The Big Ideas Whole Project Thinking Integrate the Team, Onboarding a mu

Free Energy is good energy cascade, climate, waste heat, day

Design Goal: building heats and cools passively, minimal HVAC

Climate driven form supports low energy use

Simple controls are best minimize technology (simple lighting Get the building form and envelope to do most of the work


19/19

Most people have the will to win, but few have the will to prepare
