	Research Report - The case for MVHR The paper discusses Mechanical Ventilation and Heat Recovery (MVHR) systems in UK homes, which extract warm but potentially stale air from bathrooms, kitchens, and utility rooms. They transfer the heat to fresh outdoor air through a heat exchanger. Despite being beneficial in various domestic situations, MVHR systems are relatively niche in the UK, with trickle ventilation and single-room extract fans being more commonly used. The paper challenges this convention and advocates for wider adoption of MVHR systems in both new-build and retrofit projects.	2020	Passivhaus Trust (PHT), UK
	Technical Guidance - Good practice guide to MVHR for single dwellings Passivhaus guidelines lack need explicit requirements for MVHR system specification, leading to consiconsistently disputes. The document provides specific design guidance for MVHR systems in single dwellings, complementing the ventilation protocol worksheet. Qualified and experienced parties, including Passivhaus consultants and ventilation designers, are recommended for successful implementation. This guidance serves as an addendum to the 'How to build a Passivhaus: Rules of thumb' document, offering valuable design insights not found elsewhere.	2018	Passivhaus Trust (PHT), UK
