Here you will find a range of downloadable technical papers and magazine articles that we have written relating to low energy buildings and Passivhaus in particular.
Developing Summer Comfort Design Guidance, Vienna 2017
PHPP provides excellent tools to model overheating. However the impact of design assumptions are very significant. This paper, co-authored with Passivhaus Architect Mark Siddall, outlines recommendations that have been developed by the UK PassivhausTrust to address this problem. Download designing for summer comfort Vienna 2017.
The first Passivhaus (sic) archive in the UK draws considerable inspiration from the passive (sic) approach to archive and museum storage developed by Tim Padfield and colleagues in Denmark. Performance has exceeded expectations suggesting considerable simplification would be possible in future. Download The first Passivhaus Archive in the UK.
Simple and cheap heating systems for individual Passive Houses, Darmstadt 2016
This paper by Alan Clarke provides guidance on simple heating systems for single family houses using standard gas boilers or heat pumps. Simplified radiator or floor heating systems suit the low heat load of passive houses with reduced installation cost. Performance is demonstrated with monitoring of room and heating system temperatures. Download simple heating systems paper here.
This paper with Alan Clarke, outlines how lessons from building three of the first Passivhaus Primary schools in the UK were fed into the design, construction and operation of the fourth. Many improvements resulted in both improved comfort and energy performance as well as reduced cost. Presented at the 19th International Passivhaus Conference in Leipzig 2015.

Heat loss via internal drainage vent pipes, Leipzig 2015
This paper with Alan Clarke examines heat loss to internal soil vent pipes (SVPs) that are vented to outdoors. A 2-page poster version was presented at the International Passivhaus Conference in Leipzig 17-18th April 2015. Down load Heat loss via internal drainage vent pipes, full version, here. Thanks to Ruth Busbridge for allowing us to drill holes and monitor the drains in her Passivhaus.
A simple IHG algorithm is proposed that provides a more realistic approximation of internal gains. Interestingly this makes even very small Passivhaus dwellings possible and greatly reduces the cost of achieving the standard for smaller than average dwellings.
This article in Passive House+ Magazine builds on the internal heat gains paper. The analysis concludes that, contrary to popular belief, even really small Passivhaus buildings should work very well.

“Unlike popular terms like eco, green & sustainable, passive house has a specific meaning & shouldn’t be used incorrectly, argues Passivhaus Trust technical director Nick Grant.’ Article written for Passive House+ Magazine and kindly made available for download Here.
The importance of hot water system design in the Passivhaus, Dresden 2010
For super insulated, energy efficient buildings, hot water energy use can typically exceed space heating energy use. Whilst hot water use is very dependent on user behaviour, hot water system losses can exceed this and are dependent on the building and services design. Presented at the 14th International Passivhaus Conference in Dresden. Authors: A Clarke, N Grant. May 2010 Download paper and presentation
School kitchen present a significant challenge if user comfort is to be improved without increasing energy use due to typically high levels of ventilation. The approach outlined in this paper is based on experience with three Passivaus Schools built in the UK. Presented by Alan Clarke at 16th International Passivhaus Conference in Hannover.

Biomass a burning issue 2010
In which we argue that burning biomass is renewable but no solution to reducing CO2 emissions.

Whilst some missed the point and assumed we are pro fossil fuel others got it and did an even better job of explaining the arguments. We found this piece by Mark Brinkley very amusing. We were also pleasantly surprised to find Rob Hopkins of the Transition movement supportive with an excellent and intelligent discussion – post here.
