Low-cost acoustic force trap in a microfluidic channel

A low-cost glass-based microfluidic flow cell with a piezo actuator is built using off-the-shelf parts (total cost €9 per device) to apply acoustophoretic force on polystyrene micro-beads. The main challenge in the fabrication of these devices was to ensure their leak tightness, which we solved using double-sided tape and nail polish. Beads...

Transaction costs (TCs) in green building (GB) incentive schemes: Gross Floor Area (GFA) Concession Scheme in Hong Kong

It is claimed that transaction costs (TCs) affect the effectiveness of any green building (GB) policy. However, few studies have empirically applied TC analysis to GB incentives, which normally should have analyzed the TCs borne by different stakeholders. These include TC typology and determinants during the implementation process, especially...

Costs and Benefits of Implementing Green Building Policy

Green building (GB) policies have been implemented to promote GB and address climate change. Most of the existing literatures have studied the costs and benefits of developing GB, without considerations of GB policies’ impacts. This paper aims to study costs and benefits of implementing GB policy from developers’ perspective. It takes the Gross...

Transaction Costs (TCs) in Building Regulations and Control for Green Buildings: Case Study of Hong Kong

About 40% of global energy consumption and nearly one-third of global CO2 emissions are on account of buildings. In Hong Kong, buildings consume up to 90% of electricity during construction and operation, where all the design and construction of private developments is subject to control under the Buildings<br/>Ordinance. The way building...
