Links for July 23rd through July 27th

July 28th, 2010

These are my links for July 23rd through July 27th:

  • Worldchanging: Bright Green: Transition Towns or Bright Green Cities? – Read the whole article: “That sort of casual eagerness for the death of others is appalling. Worse, the strategy implicit in this vision of transitioning — that there can be local soft landings in the event of a global hard crash, that indeed the only proper scale at which to prepare for a soft landing is at the local level, and that perhaps collapse will solve some of our problems — is delusional.
    Collapse is not a tool for social change. …. Anyone who thinks an energy descent plan prepared by a community group future-proofs them against people like Charles Taylor has simply taken a vacation from reality.
    Local efforts can’t protect against the violence of a systemic breakdown. …To plan for the collapse of large-scale systems is to plan for widespread evil and suffering; ethical planning for the collapse is impossible: post-collapse idealism is oxymoronic.”
  • All power to the wind – it cuts your electricity bills – opinion – 26 July 2010 – New Scientist – “Insofar as there is a problem, it lies in handing control of industrial policy to marginally priced markets. Market-based decisions are not technology-neutral. They favour short-term profits, and that encourages the building of power stations with low capital costs and high marginal costs. That means gas-fired plants, which are tailored to make a profit whether the spot price is high or low.
    In fact, hardly any nuclear or coal-fired plants have been built in the past 15 years, only gas-fired plants, along with renewables installed thanks to support mechanisms such as feed-in tariffs.
    If those mechanisms had been ruled to be market-distorting subsidies and removed, leaving the market to make all the calls, we would see nothing but new gas plants built. This would leave us vulnerable, wondering where tomorrow’s natural gas, on which we would be utterly dependent, would come from – a scenario that has only been prevented because wind turbines receive support.”
  • Linking Green Buildings, Productivity and the Bottom Line | Buildings | GreenBiz.com – Interesting stats: “Indeed, the 2003 California report found average annual employee costs to be 10.25 times larger than the cost of space per employee. The author extrapolates these findings to calculate that a 1 percent productivity increase would therefore have a financial impact over time roughly equal to reducing property costs by 10 percent.”
  • More than Passive – Michelle Kaufmann Studio – “Although he is introduced to me as “one of the world’s great Passivhaus experts” (and having designed over 100 built Passivhaus homes, he has earned this title), Walter is quick to respond saying that is not the title he wants. He clarifies in our conversation as well as during his very compelling presentation the next day. While Walter commends the Passivhaus intentions, he says that it is about more than that. It is about good design. “Designing a Passivhaus is easy. But we need to make sure we are designing good Architecture as well.” It is much more than just calculations and scientific numbers. “Good architecture is not a scientific result.” His message resonates strongly, as this is a fear of green rating programs in general (whether it be LEED, or other), that some architects will simply follow the checklist and not innovate or design.”
  • A Bold New Model for Sustainable Cities – Robert G. Eccles and Amy C. Edmondson – HBS Faculty – Harvard Business Review – “Unlike the real estate developers doing places like Masdar in Abu Dhabi, New Songdo City outside Seoul, and Dongtan in Shanghai (basically “green” real estate plays with a “let’s build it and hope they come” approach), Living PlanIT’s model is to create an ecosystem of large and small company partners that will focus on creating products and services for sustainable urbanization. The people that the partners bring in to produce those products and services will be the anchor occupants of the model city. The hope is that this activity will then attract other businesses and inhabitants.”
  • Commercial Lighting Solutions: Login – With lighting set to be the bete noir of Part L 2010, this looks intriguing (but US based): “The Commercial Lighting Solutions provide actionable “how to” guidance on ways to improve your building interior lighting efficiency and reduce your energy consumption, without compromising quality design criteria. Strategies include the use of high performance commercially available products, daylighting, and lighting controls, all within the context of integrated designs supported by performance specifications.”
  • A Reporter at Large: The Island in the Wind : The New Yorker – Fascinating article on renewable energy in Denmark: “The biggest disappointment, though, had to do with consumption.
    “We made several programs for energy savings,” he told me. “But people are acting—what do you call it?—irresponsibly. They behave like monkeys.” For example, families that insulated their homes better also tended to heat more rooms, “so we ended up with zero.” Essentially, he said, energy use on the island has remained constant for the past decade.”
  • Building4Change : Are airtight homes good or bad for occupant health? – “There is already strong evidence that energy efficient homes have a positive impact on occupants’ physical and mental wellbeing. Basic improvements in indoor temperature levels in winter and reduction in fuel poverty can have a significant impact. But there is a shortage of evidence to inform decision-making in this area and it is vital that risks to public health are not increased
    There are a number of areas where more knowledge is needed. Although 0.5 air changes per hour is the accepted norm, we lack a definitive assessment of a safe minimum level of ventilation. There is no comprehensive study on the part that home ventilation plays in ensuring health. We have insufficient knowledge of the actual ventilation rates being achieved in UK homes, impacts of ventilation system design, installation and operation, and impacts of occupant behaviour.”
  • How to test your decision-making instincts – McKinsey Quarterly – Strategy – Strategic Thinking – This means that to protect decisions against bias, we first need to know when we can trust our gut feelings, confident that they are drawing on appropriate experiences and emotions. There are four tests.
    1. The familiarity test: Have we frequently experienced identical or similar situations?
    2. The feedback test: Did we get reliable feedback in past situations?
    3. The measured-emotions test: Are the emotions we have experienced in similar or related situations measured?
    4. The independence test: Are we likely to be influenced by any inappropriate personal interests or attachments?
  • Enough With Jane Jacobs Already | By Andrew Manshel – WSJ.com – An odd article, but it reminded me of the existence of Whyte’s video “The Social Life of Small Urban Spaces”, which can be found online, worth hunting out: “More attention ought to be paid to the finely grained thinking of William H. Whyte and less to Jacobs’s overblown pronouncements and unprovable theories. Whyte was a close observer of people’s behavior in public spaces and emphasized the importance of the many subtle design features that make people comfortable in parks, plazas and public buildings. Following Whyte, designers, planners and community members need to pay more attention to proven, good ideas, to established data and to the fine points of landscapes and buildings.”
  • They don’t build them like they used to: Steve Mouzon’s Original Green | Kaid Benfield’s Blog | Switchboard, from NRDC – ‘Original green’ means common-sense things like building with high ceilings, cross-ventilation and shading in warm climates, and building with steep roofs and southern exposure in cool ones. It means using original forms of transportation, such as walking and bicycling, whenever possible, and designing and inhabiting communities that facilitate such self-propulsion. It means growing food nearby, and ‘living local’ as much as possible. It means accepting a wider ‘comfort range’ of temperature; our ancestors, Steve points out, were adaptable and reasonably comfortable within a range of 30 degrees or so Fahrenheit; today people fight over two degrees’ difference in ‘thermostat wars.’ Original green places and buildings have intinsically smaller environmental footprints than conventional buildings and places, especially when lifecycle effects are included, and in many cases even if the conventional ones have the benefit of green technology.
  • Theses on Sustainability | Orion Magazine – Worth reading the entire artcile: “THE TERM HAS BECOME so widely used that it is in danger of meaning nothing. It has been applied to all manner of activities in an effort to give those activities the gloss of moral imperative, the cachet of environmental enlightenment.”
  • Dynamic Thermal Properties Calculator – Free excel tool, includes decrement, admittance and kappa values: “The motivation for producing this tool is a growing need among architects and engineers for more information about the thermal properties of construction elements other than just their U-value. This is needed to help optimise the passive performance of buildings and ensure a high level of inherent energy efficiency. Going forward, it is likely that far more attention will be paid to getting this right given the forthcoming changes to Part L and SAP. Another driver is the issue of climate change adaptation, which is starting to result in greater scrutiny construction materials and their thermal properties.”
  • Climate change weather file generator – CCWeatherGen – Adaptation is flavour of the month: “The CCWeatherGen tool allows you to generate TMY2 or EPW climate change weather files with a few mouse clicks. You can produce ‘morphed’ climate change as well as ‘unmorphed’ present day TMY2 and EPW files from the original CIBSE/Met Office TRY/DSY format files. The CCWeatherGen tool is made available free of charge. However, it is solely distributed WITHOUT the required baseline weather files and/or climate change scenario data!”
  • 2degrees : Discussion Topic – “BSI has announced the launch of its new Kitemark® scheme for Energy Reduction Verification (ERV) which will independently verify and certify those organisations that achieve a reduction in carbon emissions through lower energy use. The Environment Agency has approved the scheme as one of the Early Action Metrics that contribute to the CRC Energy Efficiency Scheme, the UK’s mandatory climate change and energy saving scheme.”

Links for September 25th through October 1st

October 2nd, 2009

These are my links for September 25th through October 1st:

  • "Passive" Heating and Cooling Is a Misnomer. It’s Active. : TreeHugger – "there are 36 Billion square feet of non-residential buildings from the 50s through the 80s that need to be retrofitted and greened. It ain't going to be easy."
  • AIArchitect This Week | Buildings Brought to Life: The First Project to Meet the Living Building Challenge Is Only Months Away – "For a building to meet the Living Building Challenge it must consume net-zero energy and water. It must produce net-zero waste. It must choose an ecologically responsible site and maintain it. Inherently unsustainable materials (like lead, mercury, and formaldehyde) are not allowed, and there’s a limited radius from which materials can be transported to the building site during construction. Indoor air quality must be maintained, and, among many other requirements, all of these sustainability features must be featured in educational materials and programs at the building. Since the challenge was formulated in 2006, no building has met it."
  • Don’t Underestimate the Power of Information in Pursuing Sustainability | GreenerBuildings.com – "The Energy Passport is a related idea that could be implemented much more easily. Conceived in the early '90s by Dr. Yuri Matrosov of the Moscow Center for Energy Efficiency (CENEf), Energy Passport programs were first adopted in Moscow, then in Germany, which is now pushing for it to be implemented in the EU as a whole.
    The initial Energy Passport is based on modeled energy use and then actual energy use is compared each year with predicted use, which then could be accessed by tenants and others. Clearly, comparing actual energy use with predicted energy use, as well as consumption trends over time, would give designers and developers an incentive to get the prediction right in the first place (parenthetical note, without clear modeling rules it is shockingly easy to game the results of energy models), as well as provide a clear benchmark for operators to manage their buildings more closely."
  • Glass Industry Raises Concerns Over ASHRAE 90.1 Revisions That Could Reduce the Use of Glass in Nonresidential Buildings – Impact of potential changes to prescriptive route for ASHRAE 90.1 (similar to old elemental method for Part L) for glazing: "The proposal does not recognize or accommodate the need for different glazing solutions across climate zones. It is a "one size fits all" approach and will limit the glazing choice to a small range of high transmission, clear low-E glazings. They are not the appropriate products in all climate zones, especially the Southern cooling-dominated climates because of the sunlight intensity. Use of such high transmission glass in those climate zones will likely result in greater use of blinds resulting in increasing lighting energy usage.
    …There is only limited possibility for saving energy in buildings unless the space also includes automatic daylighting controls. Even with recent proposals, daylighting controls are only required in rooms where the "primary side-lighted area" is less than 1,000 square feet. …"
  • How to keep your mouth shut « Scott Berkun – Oh, I have been here many times. Like Scott, I'm recovering ;o). Read the whole post: "But then later on, in a new job at Microsoft in a group known as MSTE, I discovered a world of dysfunction, despair and passive/aggression. No one spoke their mind in public. Few people worked hard or asked tough questions. Quality of work, and morale, was low. So I soon felt obligated to mention these facts as often and as loudly as possible to leadership. I even expected to be rewarded for telling people how bad things were. Why wouldn’t they want to hear this? I thought.
    Before I knew it, I was that guy. The guy who always complains."
  • 500 Internal Server Error – 500 Internal Server Error
  • Constructing Excellence in the Built Environment » Blog Archive » Ethics and the Built Environment (by Jon de Souza) – If consultants only get involved at the Jus in Bello stage, is it ethical to build immoral buildings? Waiting avidly for part 2: "At present, the discussions about ethical behaviours in construction largely consider what happens after a decision has been taken to construct – the Jus In Buildo stage if you will. (Told you). What is missing is consideration of that former stage – the question asked is “can we build it”, but not “should we”. This seems to chime with our view of the world – that there are some things that simply shouldn’t be built. I mean, can any of us really morally defend snow domes in Dubai?"
  • UK notches strong gains in renewable capacity in 2008 – Politics – Renewable energy news – Recharge – wind, solar, biofuels, wave/tidal/hydro and geothermal – "The UK’s installed renewable generation capacity surged 19% in 2008, thanks largely to a 727 megawatt (MW) increase in onshore wind capacity and a 192MW boost in offshore wind, according to new government statistics.
    At the same time, the amount of electricity produced from renewables in the UK rose a more modest 10%, to 21.6 gigawatt hours (GWh)."

Enticing girls (and boys) into engineering…

May 12th, 2006

bConstructive

I almost fell off the sofa last week when I saw this ad on TV. According to the Construction Skills website:

‘The new advertising campaign ‘Make Your Mark’ features iconic buildings, which come to life in a specially animated style, evoking the sense of dreams becoming reality. For the first time this year we will be running an interactive TV campaign, where by young people can pass us their details and opt into the on going email communication campaign through the red button on their television set. To maintain recognition with our core target audience, the advert has a distinctive voiceover from T4 presenter June Sarpong to reach young women without alienating young men.’

The accompanying website can be found at www.bconstructive.co.uk. It’s ok, but I think they’ve missed a trick by not emphasising the sustainability side of things. Under building services engineering they describe the role as:

Your house or college wouldn’t be much fun to be in without a building services engineer. For a start, it would be cold and dark – and you’d be pretty smelly! It’s their job to design, install and maintain the essential services such as gas, electricity, water, heating and lighting – as well as many you probably don’t give much thought to. These all help to make buildings comfortable and healthy places to live and work in.

If this sounds like your cup of tea, you’ve probably already got a healthy interest in science, especially physics. On top of this, you’ll also need to be keen on protecting the environment, because you’ll be making sure that all types of energy are used properly and efficiently. For more info on what it takes to make it as a building services engineer, visit www.cibse.org.’

They also reckon an associate architect earns £5k more than a senior engineer. Hmmm. Not sure about that. The latest salary survey (registration required – published May last year – which means a new one out imminently) at BSJ puts senior building services design engineers (30 y.o. working towards chartership) on a national average of £32,538, £4.5k more than the bConstructive site. Whilst RIBA have a private practice salaried 30 y.o. architect on £31,500. Score! The most the architects make is £67,000 by the time they hit 50 and have their own practice, whilst BSE has a Partner, chartered in Yorkshire at 45 y.o. on £61,500 max. Not too shoddy.

How can we persuade young folk to become engineers? If the figures above don’t persuade them, then what more can we do? Attracting young engineers is currently vying with the Peter Principle (a post for another day) as the biggest challenge facing the industry today. Do we know how to appeal to the myspace generation? It should be easy – compare building simulation to creating cities in SimCity? Fairly similar skills required (the ability to think in 3D, think ahead, visualise, etc).

Is the key schools? Would a leaflet from an employer be enough to persuade someone sitting in a classroom to do a degree in architectural engineering?

No, I think we need a groovy TV show a la CSI – apparently enrollment in forensics degrees have skyrocketed…

(If readers have an interest in youth culture and the whole myspace phenomenon, Danah at Apophenia has some good observations)

Update: Just found this link on BBC :

Writers are being offered £35,000-worth of prizes to feature engineering characters on stage, screen or radio.
