Over the past 30 years, Nova has conducted more than a million household surveys across more than 100 communities. These surveys have supported the work of industries, development agencies, universities, and research institutions across a wide range of research areas.
Nova offers both standardised and customised survey services. Over time, we’ve developed a set of quantitative and qualitative survey tools that are used regularly, but we also design and implement surveys tailored to the specific needs of clients or projects.
A core part of Nova’s approach is to recruit and train people from the study community to serve as the fieldworkers for each survey. This ensures that the data is collected by those who understand the local context — and just as importantly, that the work itself builds skills and capacity within the community.
Nova’s services cover the full process, including:
The CSS aims to identify and determine the prevalence of different sources of air pollution in a community of interest. Fieldworkers are sent on unique routes through the community every day to look for any active or potential sources of air pollution as well as any signs of a recent, but historical air polluting event (such as a veld fire). All observations are captured in-situ on a digital data collection platform and accompanied by GPS coordinates pin-pointing the location of the observation. Photos are also taken of each of the sources encountered. In most cases, this survey is used to help entities determine the potential for air quality offsets in specific community.

Nova’s Detailed Energy Survey focusses on households’ energy usage habits. It gathers information on the way households use energy carriers such as coal, wood, LPG, paraffin, and electricity. Households are interviewed individually to gather data on quantities used per energy carrier, the household’s monthly expenditure on each energy carrier, the devices in or with which the different energy carriers are used, the types of residential structures in which the energy carriers are used, the purposes for which each energy carrier is used, as well as any seasonal patterns to the household’s usage habits.
The survey also evaluates respondents’ perceptions about air quality, the causes of air pollution and the safety of the different energy carriers. It is a highly comprehensive questionnaire with the current version spanning 252 questions distributed across 22 sections. The survey can be used to inform the development, planning, implementation, and monitoring and evaluation of air quality offset programmes.
Since 2010 Nova has been conducting air pollution and health surveys for clients such as the Council for Scientific and Industrial Research (CSIR), the South African Medical Research Council (SAMRC) and the Western Cape Government. Such surveys typically assess the self-reported health of household members, prevalence of diseases (esp. pneumonia, bronchitis, cancer, arthritis, high blood pressure, cholesterol, diabetes, diarrhoea, tuberculosis, asthma, and heart conditions), exposures to health risks (via water, sanitation, solid waste or refuse, and usage of solid fuels as energy carriers), immunisation, impact of health on daily activities (e.g. absence or restricted activity days), symptoms experienced in the recent past, nutrition, access to health care services, personal hygiene, socio-economic factors (income, possessions) that can influence health and air quality, and also the effectiveness of households’ residential structures in providing insulation against temperature extremes and air pollution.

The general household survey is a comprehensive, questionnaire-based survey that collects data about respondents’ demographics, subjective wellbeing, education, health, energy usage preferences and patterns, living conditions, residential structures, access to water and proper sanitation, access to solid waste collection services or proper disposal facilities, healthcare, income, and experiences related to safety and crime in their communities. The survey can be used in combination with other tools to assess the quality of life of households and communities.
