Six ways to help fix energy hardship in New Zealand

Energy hardship is caused by the interaction of factors including housing quality, appliance efficiency, energy source and price, and occupant needs and income. Multiple policy approaches are needed to address these varied causes of energy hardship, and the lack of an official definition and a measurement strategy in Aotearoa should not preclude policy action to address this critical social determinant of health. Here we outline six ways to help fix energy hardship in New Zealand

Cold New Zealand Council Housing Getting an Upgrade

As people spend most of their time at home, residential thermal conditions are important. Central government debate about minimum temperature requirements for rental properties requires an evidence base of indoor temperature data. We collected temperature, humidity and energy data from 49 council housing dwellings in Wellington over winter, and self-reported thermal comfort and heating behaviour. Mean indoor temperature was 14.9°C, colder than the national average, with 67% of readings under 16°C, which the World Health Organization associates with health implications. With New Zealand’s high rate of excess winter mortality and children hospitalised for housing-related diseases, cold housing should be addressed

Research-informed Public Policy a case study of housing

Coordinating the timing and relevance of research for public policy is difficult. Based on ongoing early collaborations between researchers and policy analysts, this case study documents innovative research led public policy. He Kāinga Oranga, the Housing and Health Programme addresses the determinants of population health by improving substandard housing and was developed in consultation with local and central government, iwi and communities. We outline our research goals and processes and the range and impact of our outcomes, and draw conclusions about the value of long-term government-funded research investment that is focused on key policy issues, to improve the effectiveness and equity of public policy

To what extent has COVID-19 impacted hard-to-reach energy audiences?

Energy users who don’t participate in efficiency and conservation programmes despite ongoing outreach are often referred to as ‘Hard-to-Reach’ (HTR). These individuals or organisations can include, e.g., low income or vulnerable households; renters; and small businesses. More effectively engaging HTR audiences is key to ensuring everyone benefits equitably from low-carbon energy transitions and related (policy) interventions. This is even more so the case in light of the COVID-19 pandemic, and the ongoing implications for energy use and affordability for the most vulnerable (and newly-vulnerable) members of our society.Within this context, the main purpose of this paper is to explore the extent to which HTR energy audiences have been impacted by COVID-19. Our primary method for this work was a comprehensive, critical literature review and a compilation of official statistics. We also collected survey, interview and focus group data during 2020 COVID-19 pandemic responses in the U.S., UK, NZ and Sweden. The geographical scope is determined by a 3-year project focusing on HTR energy users and implemented in partnership with the User-Centred Energy Systems Technology Collaboration Programme (Users TCP) by the International Energy Agency (IEA). Key findings we highlight and discuss in this paper:● Sweden has taken a different approach to manage COVID-19, yet when it comes to mobility, declines in demand (~25%) have shown relatively similar patterns to countries with stricter measures. ● In the UK, energy debt is growing due to higher domestic consumption arising from lockdown measures and the reduced income of many households. Most households (72%) have increased their energy (monthly gas and electricity bills are up £32) use. In response, 36% are turning thermostats down and 27% limiting lighting.● In the U.S., a survey of 1,000 energy customers found that more than 50% are using more energy, and monitoring their energy use less; 15% reported postponing a utility bill. ● NZ’s model COVID-19 “elimination” response has included housing, financial support, and specific energy payments to date, though unhealthy and unaffordable housing remains a major issue.Whereas the pandemic has exacerbated several elements of the HTR policy discourse (e.g. impacts on vulnerable and/or low-income households), our findings also reveal several opportunities and critical aspects for policy makers, researchers and utilities to identify and engage HTR energy users

Effects of improved home heating on asthma in community dwelling children: randomised controlled trial

Objective To assess whether non-polluting, more effective home heating (heat pump, wood pellet burner, flued gas) has a positive effect on the health of children with asthma

Warm homes: Drivers of the demand for heating in the residential sector in New Zealand

New Zealand houses are large, often poorly constructed and heated, by OECD standards, and consequently are colder and damper indoors than recommended by the World Health Organisation. This affects both the energy consumption and the health of households. The traditional New Zealand household pattern of only heating one room of the house has been unchanged for decades, although there has been substantial market penetration of unflued gas heaters and more recently heat pumps. This paper describes the residential sector and the results of two community-based trials of housing and heating interventions that have been designed to measure the impact of (1) retrofitting insulation and (2) replacing unflued gas heaters and electric resistance heaters with heat pumps, wood pellet burners and flued gas heaters. The paper describes findings on the rebound effect or 'take-back'--the extent to which households take the gains from insulation and heating improvements as comfort (higher temperatures) rather than energy savings, and compares energy-saving patterns with those suggested by an earlier study. Findings on these aspects of household space heating are discussed in the context of the New Zealand government's policy drive for a more sustainable energy system, and the implications for climate change policy.Residential energy demand Insulation Space heating

Retrofitting houses with insulation to reduce health inequalities: a clustered, randomised trial in community settings." Social Science and Medicine.

Abstract Housing is one of the key determinants of health, but it has been a relatively neglected area for interventions targeting health. There has been very little research that has shown housing interventions are effective in improving health as housing interventions are complex and resource intensive. This study examined the health consequences of insulating New Zealand homes with a standard intervention package delivered by specially trained community retrofit teams in partnership with local organisations. The package was provided through a Government funded retrofit programme carried out by community groups throughout the country. Nearly fourteen hundred households in seven communities participated. Baseline measures of temperature and fuel use, and health care utilisation were collected during the winter months of 2001. Households were then randomised and those in th
