Corporations should not be involved in elections

Corporations are not people, even though the US Supreme Court seems to think so.

I think its despicable that they are involved in election funding. The $1 million that News Corporation gave to the Republicans is tainted.

Rupert Murdoch and his buddies should stick to their knitting.

Since the right wing [...]

Some projects at or Near Completion

I have been working 6 days a week this summer, helping to push some projects to completion.
I am now frequently on-site at the Bethesda National Military Medical Center in Maryland, to oversee testing on many M/E/P/Data/Comm systems being installed in 700,000 sf of new clinic, lab, and patient care space, as well as over 200,000 sf [...]

Building Re-commissioning

A review of

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. [...]

A Flow Chart for commissioning

Alright, I will get off my high horse now and back on my regular horse. Back on the subject of energy and high performance buildings. Recently I have had the good fortune of connecting with some very good people and I am busy again at my profession. I am working with [...]

Global warming : just the facts, Ma’am

Some people in communications, and in the real estate and investment arena, have been making assertions that green buildings have economic benefits not worth the trouble and expense. This is to imply that improving energy efficiency and measuring the results is not worth the trouble. I say B.S.

I am not interested in casting [...]

Design firm uses a lot of technology (BIM and cloud computing)

BIM, IPD and “private” cloud computing at Little Diversified Architecture in Charlotte. This firm is on the top of the wave of change, being led by the author of the article, Chris France, CIO of the firm. This firm and its predecessors have always been very very good anyway. [...]

Modularity and HVAC systems design

Simple is as simple does. It works. Its easier to understand. Easier to fix. The real world does not reward complexity.

An important aspect of good design is simplicity. HVAC can be complicated enough, given the need to maintain various spaces at set temperatures, relative humidity and cleanliness. HVAC systems are also expected to maintain certain pressurization and [code required] outside air exchange. All while keeping to the highest possible energy efficiency. We also need and expect them to respond precisely and correctly to changing variables.

Simplicity in controls are also key to this. The simplest controls are on-off. Simplicity is not obvious everywhere. But in reality, as software development theory teaches, you can find the simple by decomposing the complicated.

Consider these concepts before the initial Basis of Design is established. Decompose the various functions needed and decide how the system will be controlled. Many designers have their personal preferences and presumptions, but these must be put aside in favor of open-mindedness in the beginning of the decision making process. Yes, energy and size calculations may be useful, but not as important as what and how to control the various environmental parameters.

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 [...]

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.

BIM is a database – Naming is important

Delayed commentary on things learned and shared at a recent RevitDC meeting:

NAMING THINGS and SHARING (it’s a matter of INTEGRITY)
Naming comes up again. “Inconsistent” is the keyword. I am glad that I am not the only one who struggles with it. Shakespeare wrote “What’s in a name? That which we call [...]
