What is Green or Sustainable?
“Green” Building is:
Kermit the Frog’s House?
Any building painted with Benjamin Moore #2034-40 Cedar Green ?
Any ivy covered building at Harvard??
Also known as Green Construction or Sustainable Building, Green Building refers to building processes that are environmentally responsible and resource-efficient throughout a building's life-cycle: from site selection to design, construction, operation, maintenance, renovation, and demolition.

✔

“Sustainable architecture seeks to minimize the negative environmental impact of buildings by enhancing efficiency and moderation in the use of materials, energy, and development space.”
-Wikipedia
What is Green or Sustainable?
Buildings account for 40% of U.S. energy use*

Energy Codes Today
Building codes start as life safety/construction
Energy codes in U.S. have been standardized through IECC
Massachusetts has adopted IECC
MA jurisdictions have the option of using the ‘stretch’ code
Stretch code dictates 35-40% reduction in building energy usage over base code.

Actual Energy Consumption Comparison
For single family houses in Denmark

Beyond Code - LEED
USGBC LEED Program:
Not-for-profit trade organization
The largest ‘sustainable’ rating program in the U.S.
Energy savings debatable
Rates issues beyond energy
6 criteria for measurement

Case in Point: LEED-EB v2.0 Silver Certification
Challenges:
Existing building vs. new
Occupant and Owner Green awareness
Tight budget
High traffic area, needed to minimize disruption
Needed to identify areas of opportunity
Required a team approach
Conducted a retro-commissioning energy study

Case Results
Achieved ENERGY STAR score of 72
NYSERDA (New York State Energy Research and Development Authority) provided 50% cost sharing
Operational gains:
Reduced potable water by 10% over EPA 1992 standards
Implemented extensive ozone protection through active management of refrigerants
Powered by Green-e energy for electricity
Diverted over 70% of building waste from landfill
85% efficiency (MERV 14) air filters to provide proper indoor air quality
Office efficiencies:
Sustainable purchasing of office materials, green cleaning paper products, and light bulbs
50% of office spaces have lighting controllability
High performance green cleaning featuring Green Seal certified cleaning products, equipment and pest management
Delivered Green Education to Occupants:
Shared green building exterior management practices and preventive maintenance program
Noted for exemplary performance in public transportation, development density, and occupant recycling

Beyond Code: Passive House
U.S. Energy Information Administration shows buildings are responsible for:
48% of greenhouse gas emissions annually
76% of all electricity generated by U.S. power plants goes to supply the Building Sector

Principles for a Passive House

Beyond Code - Zero-Net
CREATE
USE
“…a popular term to describe a buildings use with zero net energy consumption and zero carbon emissions annually.” - Wikipedia
By 2016, UK set the goal that all new buildings will have Zero-Net carbon footprint

Challenges
Challenges to ‘sustainable’ building standards beyond the code:
Potential suits against USGBC
“Shadow Government”
Lack of data on actual results
Construction issues
