BUILDINGS PLAY A BIG PARTBUILDINGS ACCOUNT FOR ALMOST HALF THE CO2 EMMISSIONS
energy use and CO2 emissions per capita and by sector

HOW BIG?Reference: Energy Efficiency and Renewable Energy, U.S. Dept. of Energy
U.S. BUILDINGS ACCOUNT FOR MORE EMISSIONS WORLDWIDE THAN JAPAN, FRANCE & UK COMBINED

The Problem
We design to Minimum Standards
Design – Bid – Build delivery method
We don’t use Integrated Project Delivery (IPD)
Monitoring – If you can’t measure it, you can’t manage it
Separation of funding (Building vs Operation)

MINIMIZE LOSS/GAIN:
ELIMINATING THERMAL BRIDGES IN LOW LOAD
CONSTRUCTION CAN CUT OVERALL BUILDING HEAT
LOSS IN HALF

DEFINING THE AIR-TIGHTNESS LAYER: DESIGNING WALL/ROOF/SLAB DETAILS WITH AIR-TIGHTNESS CONSIDERED
MOISTURE PERFORMANCE:AIR-TIGHTNESS

MINIMIZE LEAKAGE:ENVELOPE PENETRATIONS
Minimize penetrations OR combine: example - all plumbing fixtures to one vent or the use of AAV’s
