Evaluation Of Phase Change Materials For Cooling In A Super-Insulated Passive House, Jeffrey Stephen Lauck
Evaluation Of Phase Change Materials For Cooling In A Super-Insulated Passive House, Jeffrey Stephen Lauck
Dissertations and Theses
Due to factors such as rising energy costs, diminishing resources, and climate change, the demand for high performance buildings is on the rise. As a result, several new building standards have emerged including the Passive House Standard, a rigorous energy-use standard based on a super-insulated and very tightly sealed building envelope. The standard requires that that air infiltration is less than or equal to 0.6 air changes per hour at a 50 Pascal pressure difference, annual heating energy is less than or equal to 15kWh/m2, and total annual source energy is less than or equal to 120 kWh/m2. A common …
Benchmarking Public Private Partnership Environments: East Asian Comparisons, Michael Regan, Jim Smith, Peter Love
Benchmarking Public Private Partnership Environments: East Asian Comparisons, Michael Regan, Jim Smith, Peter Love
Michael Regan
The Public Private Partnerships (PPP) markets in Australia and the UK are considered to be the most sophisticated in the World and used as a model for benchmarking against other countries. In addition the global financial crisis also meant many PPP financiers became risk averse to certain projects and in particular countries. The environment for major infrastructure projects, particularly in ‘riskier’ countries, has become more difficult. Research conducted by the Economist Intelligence Unit for the Asian Development Bank evaluated PPP policy and programs in a number of countries in the Asia Pacific. The study benchmarks the UK and Australian PPP …

A Casual [Causal] Relationship Between Building Maintenance Market And Gdp: Hong Kong Study, Yong-Tao Tan, Liyin Shen, Craig Langston

Purpose: The purpose of this paper is to examine the causal relationship between the building maintenance market and GDP in Hong Kong. Design/methodology/approach: The Granger causality test is used to investigate the lead-lag relationships between the maintenance and repair work and GDP in Hong Kong. With regression analysis, the future trend of the maintenance market is forecasted. Findings: The results show that the growth of the economy will lead to the growth of the maintenance market, not vice-versa. And the building maintenance market in Hong Kong will keep increasing with the economy growth. Originality/value: This paper shows that the growth …
Using Purchasing Power Parity To Assess Construction Productivity, Rick Best
Using Purchasing Power Parity To Assess Construction Productivity, Rick Best
Rick Best
For many reasons comparing construction productivity between countries is a difficult task. One key problem is that of converting construction costs to a common currency. This problem can be overcome relatively simply by using a basket of construction materials and labour, termed a BLOC (Basket of Locally Obtained Commodities), as a unit of construction cost. Average BLOC costs in each location are calculated from data obtained from a number of sources (quantity surveyors, estimators). Typical building costs obtained from published construction cost data are expressed in BLOC equivalents. Lower BLOC equivalents represent higher productivity as other inputs (largely materials) are …
Quantum Man, Julian Voss-Andreae
Quantum Man, Julian Voss-Andreae
The STEAM Journal
According to quantum physics, the world is fundamentally quite different than it seems. Drawing inspiration from the underlying nature of reality, former quantum physicist Julian Voss-Andreae created an image of a walking human as a quantum object. Made up of parallel sheets of steel, the sculpture is a metaphor for the counter-intuitive world of quantum physics. Symbolizing the dual nature of matter with the appearance of classical reality on the surface and cloudy quantum behavior underneath, the sculpture seems to consist of solid steel when seen from the front, but dissolves into almost nothing when seen from the side.
