There are indications that energy-retrofitted buildings can create risks for indoor environmental quality (IEQ) and therefore for health and comfort of occupants. A review was conducted to identify and verify those risks, within three themes: building envelope, heating, ventilating and air conditioning (HVAC)-systems, and occupants. Publications from the last five years in major peer-reviewed journals from different fields (energy, buildings, indoor air, social sciences) were found by using a variety of keywords (health effects, occupant behaviours, energy-efficient retrofitting, etc.).

This report is the first report of the ‘Energy Savings 2030’-project which seeks to help the Coalition for Energy Savings to produce a robust and timely input to the 2030 policy discussion. It brings together and summarises recent empirical evidence on costs and benefits of energy efficiency measures. The evidence gap in terms of reliable ex-post data is well known. In the majority of cases results from ex-ante modelling studies inform the debate. The research carried out for this report confirms the persistent gap in publicly available ex-post evaluations of energy efficiency programmes.

The Bali Province Technical Guidelines (written in Indonesian) for Implementing Green Buildings in the Context of Clean Energy represent a collaborative effort between the Bali Provincial Government, Global Building Performance Network (GBPN), and support from CORE Udayana. Developed through extensive studies and analysis from November 2021 to June 2022, the guidelines engage stakeholders from the Provincial Government Bali, Professional Expert Team, universities, associations, private sectors, and professionals in building and clean energy.

The Samarinda City Technical Guidelines represent a strategic initiative aligned with the city's development goals, as outlined in Mayor Regulation No. 55 of 2021. These guidelines meticulously consider the potential savings and additional benefits achievable through the implementation of energy and water-efficient measures, aiming to significantly reduce carbon emissions in buildings. Spearheaded by the Samarinda City Government, this effort reflects a commitment to fostering an environmentally friendly and sustainable urban landscape.
