Building Commissioning: A Golden Opportunity for Reducing Energy Costs and Greenhouse Gas Emissions
By Evan Mills, Ph.D.
Lawrence Berkeley National Laboratory for: CEC (PIER) July 21, 2009

This white paper contains some compelling arguments in favor of re-commissioning. Money and energy are two items. A building is a kind of organism. [...]

Distractions divert us from what is important

Stephen Covey’s book, Seven Habits of Highly Effective People, says that getting to where we want to be requires focus on the “wildly” important. Covey said that it is all too easy to get off-focus from that. Instead, we get pulled off-course by the myriad of “urgent” demands in our every day lives. [...]

Dependence on oil has a BIG cost

the common Oil slick

The massive oil spill in the Gulf of Mexico is too big price to pay for our dependency on oil. Now we have to re-evaluate our energy plans. FINALLY. The sustainable approach is to stop drilling and spend more money on energy conserving measures and renewables.

Report Dispels doubts on Conservation Measures

This Lawrence Berkeley National Laboratory report, Building Commissioning: A Golden Opportunity for Reducing Energy Costs and Greenhouse-Gas Emissions should inform the skeptics about the efficacy of this process for buildings. Regular tuneups for your car are the norm, so the same should be for your building.

I quote:

President Theodore Roosevelt had it right!

Let us go back to the tried and proven. The Bush sponsored tax cuts did not do what they were supposed to do. We forgot to take Teddys advice, as quoted below.

The tax cuts did not increase our national economic vitality one wit. They should be allowed to expire [...]

Better HVAC can save $48 billion/year in the USA

The latest numbers are that US buildings consume $320 billion/year in energy. 2/5 of all the energy used in the US. And about 40% of the energy (costing $120 billion/year) is used in buildings for HVAC.

Some of the 2009 stats HVAC designs that I have incorporated recently into my office [...]

Getting a View of Energy Consumption in your building

Trends: Read the chart on your buildings energy usage. Monthly charts can usually be found on the monthly utility bills. Your utility company can provide them upon request (usually). If and when you can acquire the hourly or daily usage charts, the pattern of usage can be very revealing about whether your building is running at its best. What does a trend chart look like?

The US Department of Energy has a gather and track data process listing the following steps.

STEP 2: Assess Performance
* 2.1 Gather Data
* 2.2 Establish Baselines
* 2.3 Benchmark
* 2.4 Analyze Data
* 2.5 Technical Assessments & Audits

Here I am only discussing Step 2.1, ‘Gather data’. Continue reading Getting a View of Energy Consumption in your building

Attention general public : Buildings have the greatest energy footprint, not cars

The guys over at Autodesk made this cute animation to drive the point home

The Buildings Sector accounts for about 40% of U.S. Energy, 72% of Electricity, and 34% of Natural Gas use. Building energy costs totaled $390 billion in 2006.

THE LAST ENERGY CRISIS- 1970s and a B.S. Environmental Design

I have a BS ED, which is a science that encompasses the junction between engineering and architecture. My expertise is in buildings and how they work. I focused all my career on design of the built environment and building systems. I was educated in energy conservation, neighborhood [...]

The bottom line! Building commissioning today

I would like to share this 2006 excerpt from the Building Design and Construction magazine white paper on the bottom line of building commissioning.

To put some solid numbers on benefits of commissioning, Evan Mills, PhD, and colleagues at Lawrence Berkeley National Laboratory, Portland Energy Conservation, and Texas A&M University (Energy Systems Laboratory) reviewed published [...]
