Hi, I am Yeo Shi Jie, 0330176.
Introduction:
This assignment emphasizes the role of a walkthrough audit as a process used to establish an overall practice of the potential energy savings through visual presentation. HVAC, lighting, building maintenance and other factors affecting energy consumption of the building (in this context your own home). Simple calculation could be done to quantify the current and potential implementation of the identified Energy Conservation Measure (ECM). Usually it is carried out in 1-2 days with/without a team depending on the scale and complexity of the building with the usage of the tools (lux meter, thermometer, hygrometer) will serve the purpose. For this exercise, students will be carrying out a field measurement to establish the incoming load profile, major energy usage (segmentation), HVAC and lighting system of your own home. Followed by suggestions on the Renewable Management System (Passive Cooling/Lighting, Retrofitting Lighting system with LED light source/dimmer, Effective Waste Management, Controlling Heat/Glare with Façade or device) to achieve energy efficiency.
Objectives:
- To identify the principles of energy efficient systems and overall practice of potential energy savings through inspection.
- To evaluate energy consumption and the implementation of its strategies to reduce energy usage in design to deliver low energy architectural design.
Task/ Methodology: (Individual)
Students are required to carry out an walk-through Audit process of your own home and produce an Audit report individually on the existing and to propose strategies to achieve energy savings through focus on specific topics (Passive Cooling/Lighting, Retrofitting Lighting system with LED light source/dimmer, Effective Waste Management, Controlling Heat/Glare with Façade or device) to achieve energy efficiency.
a. Façade and Climate Based Profile of your own home (introduction on orientation, sun path and wind direction, external and internal temperature, humidity, illuminance level, air speed).
b. Energy Load Profiles (working on hourly, daily, weekly, monthly of electrical appliances energy load).
c. Energy Consumption Pattern (graphs, chart on hourly, daily load profile).
d. Energy System and Energy Saving Potential (proposed strategies) .
e. Energy Management (Waste/Water observation on water usage and occupant behaviour as well as for future recommendations to save energy).
> Get the latest electricity bill
> Inventory list of electrical appliances in an inventory table
> Draft the inventory table according to space, electrical appliances, watt per appliance, hours of usage per day
> Compare weekdays and weekend energy usage and cost then identify what cause the differences and possible CO2 emissions
> Report the observation of occupant activities and behaviour towards energy usage/saving
> Suggest potential energy efficiency application to reduce monthly energy consumption
Outcomes:
1. Reports:
2. Overall Board:
Learning Outcomes:
- Identify the principles of energy efficient systems in architecture and building technology.
- Apply strategies of renewable energy to deliver low energy architectural design.
