RESEARCH PAPER

Motivation

Household electricity consumption in Singapore has increased by about 17% over the past decade, according to a report by the National Environment Agency in May 2018. On aggregate levels, Singapore households consumed 7,295 GWh (gigawatt hours) in 2017, which roughly translates to an average expenditure of $1,000 a year on electricity per household.

Electricity consumption is a national issue, especially given that Singapore has finite energy sources. It is therefore important to encourage households to consume electricity in more sustainable ways.

Traditionally, the lack of transparency surrounding electricity use has been acknowledged as a possible challenge in raising awareness on electricity consumption. Improving visualisation of household electricity consumption can help people in Singapore gain better clarity of their consumption habits and expenditure, and thus more incentive to reduce electricity usage.

Our project visualises the distribution of household electricity consumption across planning regions in Singapore, accounting for type of residential homes, income and demographic profiles. We aim to better communicate electricity consumption in everyday life to people in Singapore, and ultimately engage them to reduce electricity consumption.

Objectives

This project aims to create an interactive data visualization dashboard to achieve the following objectives:
1. A clear geographical visualization for energy usage across subzone
2.
3.
4.

Data

Datasets	Data Attributes	Rationale Of Usage
EMA Household Energy Consumption Source: https://www.ema.gov.sg/Statistics.aspx	Postal Code Type of Dwelling Month, 2013-2016 Electricity Consumption	There are 2 groups of dataset. 1. Household monthly electricity consumption by postal code from 2013 to 2016. 2. Household yearly electricity consumption from 2007 to 2017. Those dataset will be used as the main dataset to visualise the electricity consumption in Singapore.
Singapore Residents by Planning Area and Type of Dwelling, 2000 - 2017 Source: https://www.singstat.gov.sg/find-data/search-by-theme/population/geographic-distribution/latest-data	Planning Area Type of Dwelling Resident Population Year	This dataset aims to complement the main dataset by providing detailed information about the Singapore residents distribution by planning area and type if dewlling.
HDB Property Information Source: https://data.gov.sg/dataset/hdb-property-information	Block Number Street Residential Total Dwelling Units Number of 1-room Sold Number of 2-rooms Sold Number of 3-rooms Sold Number of 4-rooms Sold Number of 5-rooms Sold Number of 5-rooms Sold Number of Executive Condominiums Sold	This dataset provide a comprehensive records of Singapore HDB Property Information. This dataset will enables us to scale the average electricity consumption by the number of units for the given dwelling type for the block.
Private Apartment Information Source: Real Estate Information System	Block Number Street Residential No of Units Property Type Postal District Postal Sector Postal Code Planning Region Planning Area	This dataset will be a complementry dataset to the HDB Property Information by providing unit information for the private Apartments.
List of Postal Districts Source: https://www.ura.gov.sg/realEstateIIWeb/resources/misc/list_of_postal_districts.htm	Postal District Postal Sector General Location	This dataset is used to map the postal code to the corresponding district.

The use of a filter dashboard action also allows the user to view information only for selected planning regions.

Challenges

Challenges	Possible Solutions
Unfamiliarity with D3.js	Independent learning through online learning resources Validating learning outcome through review and coding practices
Data merge, cleaning and transformation	Planning area electricity consumption data: Since the data provided by Energy Market Authority is an average of type of dwelling for each block, we will scale the average electricity consumption by the number of units for the given dwelling type for the block, then sum all the blocks in the relevant planning area to get the aggregate monthly consumption per planning area. Missing NA records: Due to privacy concerns, Energy Market Authority does not disclose some data points. We will examine the effect of removing the NA records to decide the appropriate action to take.
Choice of web hosting provider	A quick production pipeline required due to the time limit Examine the requirements of the data visualisation: dynamic or static Current solution is to use Github Page as a hosting provider as there is no dynamic data retrieval required
Unfamiliar with implementation efforts required for customised D3.js interactivity	We will be spending 2 weeks to familiarise ourselves with D3.js structure and syntax The following 2 weeks will involve us trying out the customised D3.js interactivity The project scope and plan will be re-examined based on the project objective, complexity and time available
