    A green technology of acoustic of fluid-structure interactions become an emerging technology today, a call thermoacoustic heat engine. Thermoacoutics heat engine systems convert the energy on a harvesting from a waste heat energy and convert to an electrical energy. That component of devices a call a hot heat exchangers. This paper study was focused on a new design of thermoacoustics heat exchanger and investigation of its performance in terms of thermal analysis. A conceptual design was produced with three designs of hot heat exchangers, which are wire-type, finger-type and star-type. Commercial code ANSYS-CFX software are used on the evaluation, the heat exchanger’s designs were simulated with two thermal conditions which are steady state and transient heat conduction. Materialselection from copper and aluminium a chosen to look-out the engagement between theoretical and numerical study. There are three inlet temperatures that are assumed will be supplied by constant waste heat which are 200°C, 350°C and 500°C.The star-type design has the highest value of heat conduction through a fin heat conduction with copper as a material which is 32.84W. Star-type hot heat exchanger recorded the fastest time to distribute temperature compared to wiretype and fingertype heat exchanger. Result shown the combination between star-type design and copper material will produce a good agreement to design a hot heat exchanger.

    The Building sector is the largest consumer of energy worldwide. Net Zero Energy Residential Building (NZERB) is one of the prudent approaches to reduce pressure on primary sources of energy. The main objective of this study is to use Taguchi simulation based on orthogonal arrays approach to optimize thermal envelope of a building, SEER value of HVAC system, lighting power density, and ventilation level to reduce the Building Energy Intensity (BEI) 50% lower than the base case building according to International Energy Conservation Codes 2015. In this study whole building energy simulation was performed by Hourly Analysis Energy Program and PVWatts calculator was used to estimate the size of the PV system for balancing the energy demand of the house. The results of Taguchi simulation approach show that by decreasing the U value of wall, windows, roof, floor to 0.1, 0.8, 0.1, 0.2 W/m2. °K respectively and ventilation rate 0.15 l/s-m2, lights of 110 lm/W and SEER of the HVAC system 4 (W/W option) reduce BEI from 147.78 kWh/m2/year for base case building to 67.085 kWh/m2/year for optimal design case. PV system size estimation was performed with PVWatts calculator. PV Watts recommended the size of 13kW DC rating system (open rack type) of 15% efficiency for the weather of Johor Bahru to meet the annual energy demand of the proposed optimal building design.

    Activated carbon can be call as “material of the future” due to its versatility usage from medical aspect, water and air treatment and a very good adsorbent characteristic. Process involved in the production of activated carbon were carbonization of raw material and activation of the charcoal to be a carbonized material. Basically the activation can be either physical or chemical activation or a combination of it. This paper is to review the potential of agricultural waste and introduce the potential base material that can be utilized as raw material for activated carbon. The process and the material selected on agricultural waste is coconut shell, palm kernel shell and rubber seed shell. The downstream industry of agricultural waste could look into material for the product development in the near future.
