The electrical energy consumption in Malaysia has increased sharply in the past few years, and modern energy efficient technologies are desperately needed for the national energy policy. This article presents a comprehensive picture of the current status of energy consumption and various energy...

A novel technique for solving a dynamic optimal chiller loading problem is presented. This method reduces the complexity of the dynamic problem by considering all chillers to be a single, optimal chiller, which significantly reduces the number of decision variables. A static optimal chiller...

Improvements in energy efficiency and renewable energy use can reduce farm operating costs and reduce greenhouse gas (GHG) emissions. Responses (n=224, representing a 32% response rate) from a mail survey were used to assess use and interest in energy efficient and renewable energy options on...

Direct energy use is a small but essential component of the farm greenhouse gas (GHG) budget. Improvements in energy efficiency and renewable energy can help reduce farm operating costs, improve air quality and reduce GHG emission levels. Energy conservation is especially important in Nova...

Historically, many resource conservation campaigns failed because they paid inadequate attention to the interests of stakeholders. As a consequence, stakeholder analysis has gained increasing attention in order to avoid potential policy failures in the related fields. However, the stakeholder...

CWNs (cooling water networks) are targeted and designed in this work by an analytical approach requiring no graphical procedures. The key basis for the approach is the conversion of the cooling duties to equivalent inlet–outlet (demand–source) pairs. The UTA (Unified Targeting Algorithm) is...

In our previous work, a significant improvement in organosilicon monomer distillation using parallel double-effect heat integration between a heavies removal column and six other columns, as well as heat integration between methyltrichlorosilane and dimethylchlorosilane columns, reduced the...

Using the analogy between heat and mass transfer processes, the recently developed entransy theory is extended in this paper to tackle the coupled heat and mass transfer processes so as to analyze and optimize the performance of evaporative cooling systems. We first introduce a few new concepts...

This paper presents a study on the integration of two building technologies into one new unified form for application in residential and small commercial and industrial buildings. Structural insulated panel (SIP) technology was utilized as a structural vehicle, and also for thermal insulation,...

Accurate calculation of the heat transfer rate across building blocks may lead to significant energy savings. Conjugate heat transfer analysis is carried out numerically to compute the heat transfer rate/R-value as the number/layout of air-filled cavities is changed. Conduction heat transfer in...
