How Accurately Does Breeam Measure Sustainability?

How accurately can we measure the W cross section?

We study the QCD sources of systematic uncertainties in the experimental extraction of the W cross section at hadron colliders. The uncertainties appear in the evaluation of the detector acceptances used to convert the number of observed events into a total production cross section. We consider the effect of NLO corrections, as well as of the inclusion of parton showers, and evaluate the impact...

How Does Integrated Reporting Change Sustainability Communications?

How Does the World Bank Measure Poverty?

There is almost never just one way to measure an economic variable, and poverty is no exception. Judgments are required about the best method—given the data available—at virtually every step, starting with the design and processing of the underlying household survey data. The judgments made should be explicit and subjected to independent review. In that spirit, Deaton (this issue) provides a us...

A comparative study of DGNB, LEED and BREEAM certificate systems in urban sustainability

Certification systems are generally used for the purpose of sustainability assessment in buildings or neighbourhoods, and indexes mainly focus on construction issues related to the civil engineering activities but not usually in urban management programs. As an attempt to tackle this issue, the “German Sustainable Building Council” has created and developed a certification system according to t...

The Challenge to Accurately Measure Irradiance

In a seminal report, about fifty years ago, Cremer, et al.(1) defined the basic principles of phototherapy as the spectral distribution for the photo-destruction of bilirubin (action spectrum ~ 400-520 nm), the effect of light intensity on the rate of bilirubin photo-degradation in vitro (t1⁄2=23 minutes, for sunlight) and the in vivo rate of bilirubin decline (–1.0 to 3.5 mg/dL/h or –17 to 60 ...
