Building energy efficiency is an important strategy for reducing greenhouse gas emissions globally. In fact, 55 countries have included building energy efficiency in their Nationally Determined Contributions (NDCs) under the Paris Agreement. This research uses building energy code implementation in six cities across different continents as case studies to assess what it may take for countries to implement the ambitions of their energy efficiency goals.

Text
English
Authors:
Yu Wang

This paper introduces the major state-level regulations and policies for improving energy efficiency in buildings. The purpose of the review is to discuss the challenges and issues in policy implementation and the latest trend in adopting innovative instruments. The implementation of customer efficiency programs increasingly incorporates non-price instruments to encourage participation and deep savings. States pay attention to not only code adoption and update but also compliance and evaluation.

Authors:
E. L. Bird, J. O. Ige, P. Pilkington, A. Pinto, C. Petrokofsky & J. Burgess-Allen

Background
The built and natural environment and health are inextricably linked. However, there is considerable debate surrounding the strength and quality of the evidence base underpinning principles of good practice for built and natural environment design in promoting health. This umbrella review aimed to assess relationships between the built and natural environment and health, concentrating on five topic areas: neighbourhood design, housing, food environment, natural and sustainable environment, and transport.

Association of residential energy efficiency retrofits with indoor environmental quality, comfort, and health: A review of empirical data

Text
English
Authors:
William J. Fisk, Brett C. Singer, Wanyu R. Chan

This paper reviews empirical data from evaluations of the influence of residential energy efficiency retrofits on indoor environmental quality conditions and self-reported thermal comfort and health. Data were extracted from 36 studies described in 44 papers plus two reports. Nearly all reviewed studies were performed in Europe or United States. Most studies evaluated retrofits of homes with low-income occupants. Indoor radon and formaldehyde concentrations tended to increase after retrofits that did not add whole-house mechanical ventilation.

A Review of the Relation between Household Indoor Temperature and Health Outcomes

Authors:
Fátima Lima, Paula Ferreira, Vítor Leal

This paper provides a review of research that addresses the relationship between indoor temperatures and health outcomes, taking into consideration studies that focus heat or cold exposure within the household context. It aims to extend previous research by considering both indoor temperatures from existing housing, and empirical studies that focus on energy efficiency measures and subsequent health impacts. To achieve this aim, a literature review was undertaken, combining engineering and health databases.

Polyurethane insulation and household products – A systematic review of their impact on indoor environmental quality

Text
English
Authors:
Dzhordzhio Naldzhiev, Dejan Mumovic, Matija Strlic

We systematically review the impact of polyurethane insulation and polyurethane household products on the indoor environmental quality of buildings. The review breaks down polyurethane products into constituent compounds (isocyanate, polyol, flame retardant, blowing agent and catalyst) as well as secondary emissions, and discusses their implications on human health. Concentrations of compounds emitted from insulation, and household materials, measured in laboratory experiments and case studies are presented in the context of the built environment.

Scoping review to understand the potential for public health impacts of transitioning to lower carbon emission technologies and policies

Text

Authors:
Rachel Tham, Geoff Morgan, Shyamali Dharmage, Guy Marks, Christine Cowie

Background: The transformation of the global energy sector from fossil-based fuels to low/non-carbon fuels will reduce environmental pollutant load, which in turn will benefit human health. However, with upscaling of emerging renewable technologies and energy sources, it is important to identify the potential for unintended health impacts, and to understand where the knowledge gaps lie with respect to health. We aimed to identify these gaps by conducting a scoping review. Methods: We conducted a systematic search of Medline, Web of Science, PubMed and EMBASE.

Adopting Decarbonization Policies for the Building and Construction Sector: Costs and Benefits

Text
English
Authors:
Peter Graham

The building sector is not on track to lower total greenhouse gas emissions. Given that emissions from the sector represent nearly 40% of global energy-and process-related emissions, this represents a serious challenge to keeping global warming to 1.5oC. The Buildings sector must therefore decarbonize.To support this goal, this report focuses on policy drivers for decarbonisation, and the costs and benefits associated with their implementation.

It is clear that city must be part of the solution if an urbanizing world is to grapple successfully with ecological challenges such as energy depletion and climate change. A system dynamics model was developed in this study using STELLA platform to model the energy consumption and CO2 emission trends for the City of Beijing over 2005–2030. Results show that the total energy demand in Beijing is predicted to reach 114.30 million tonnes coal equivalent (Mtce) by 2030, while that value in 2005 is 55.99 Mtce, which is 1.04 times higher than the level in 2005.

The Dutch Government stimulates the application of energy efficiency measures to reduce the energy requirements of buildings, which are responsible for about 20% of the Dutch CO2 emissions. For our assessment, we followed a qualitative approach, due to a lack of data. We reviewed the mix of policy instruments and used stakeholder surveys and interviews. We found that energy use is not very likely to decline fast enough to achieve the Dutch policy targets for 2020. For new buildings, the policy mix works well, but its contribution to the policy targets is limited.

In-home displays, dynamic pricing, and automated devices aim to reduce residential electricity use—overall and during peak hours. We present a meta-analysis of 32 studies of the impacts of these interventions, conducted in the US or Canada. We find that methodological problems are common in the design of these studies, leading to artificially inflated results relative to what one would expect if the interventions were implemented in the general population.

This report sets out the positive and negative impacts of improvements in energy efficiency in buildings that could come about through a recast of the Energy Performance Buildings Directive (EPBD). Successive studies have shown that energy efficiency offers many of the most cost-effective options for meeting global emission targets. In many cases, energy efficiency measures have been shown to be ‘negative cost’, meaning that it would be economically advantageous to implement them.
