    Tests the widespread belief that laying an impermeable ground bearing slab in a building with no damp-proof course drives ground moisture up the adjacent walls by capillary action. Wall, soil and atmospheric moisture content were measured over a three-year period in a historic building before and after a vapour-sealed ground floor was installed. Using timber dowel measurements, the moisture content within the adjacent rubble-fill wall did not vary in response to wall evaporation rates and did not increase after the vapour-proof barrier was installed above the floor, indicating the moisture levels in that wall were not driven by capillary rise. The finding matters because the opposite assumption is routinely used to argue against sealing a solid floor in an old house.

    Measures why hemp shiv works as an insulating aggregate, using scanning electron microscopy, CT scanning and mercury intrusion porosimetry. Findings: vessels are approximately 50 to 100 micrometres in diameter, surrounded by relatively thick fibre cells 1 to 2 micrometres in diameter, with a diffuse-porous distribution and no clear pore arrangement; pore frequency is around 20.8 vessels per square millimetre. Average accessible porosity is 76.67 plus or minus 2.03 per cent by mercury intrusion porosimetry, and between 50 and 75 per cent by CT depending on threshold and resolution. That very high porosity is the physical reason for hemp shiv's low thermal conductivity and high moisture buffer value in hemp-lime construction. Presented at the 2nd International Conference on Bio-Based Building Materials, Clermont-Ferrand, June 2017.

    Tests how the mix itself controls hemp-lime performance (Construction and Building Materials vol 159, pages 9-17, 2018). Both the binder to aggregate ratio and the aggregate particle size distribution were shown to affect compressive strength, flexural strength and thermal conductivity, so a hempcrete wall's numbers are a function of the recipe, not of the material category. The material is anisotropic in both behaviour and internal structure, meaning results differ by direction of loading, and the effect of binder to aggregate ratio is itself directionally dependent, indicating different failure mechanisms in opposing loading directions. A new image analysis method was used to study the internal topology. Practical consequence: hemp-lime properties must be specified and tested for the intended orientation and mix, and cannot be lifted from a generic figure.

    A year-long practical test of rising damp on walls built from different mortars, compared against theoretical models. Findings: mortar characteristics significantly affect the height to which damp rises, and the rate of water absorption into the mortar is the key factor determining the height of the rising damp front, with a strong correlation to the Sharp Front Model. A second measured result is useful for diagnosis: walls that had received rising damp treatment were warmer than the untreated control walls, because reducing surface moisture removes the evaporative cooling effect, which is why a damp wall reads cold to the touch and on a thermal camera. The paper reviews the controlling mechanisms of capillary effect, water absorption, evaporation and salt formation.

    Findings from the £3 million Demonstration of Energy Efficiency Potential (DEEP) project commissioned by the Department for Energy Security and Net Zero, run by Salford's Energy House Labs with the Leeds Sustainability Institute at Leeds Beckett and Loughborough University, and one of the largest UK studies of solid wall retrofit. Both a whole house approach and piecemeal retrofit cut the fabric heat loss and space heating energy bills of the Energy House by around 50 per cent, but the whole house approach carried significantly less risk of surface condensation and mould growth at junctions. Insulating solid walls could save up to 30 per cent a year on energy bills for some homes and was by far the single most effective measure for solid walled homes, with other measures unable to reach the required improvement. Modelled fuel bill savings for solid wall insulation alone were between 11 and 29 per cent depending on the condition of the wall and how much of the external wall is insulated, rising to as high as 33 per cent when combined with other measures. Measured improvements were in most cases lower than the EPC predicted. A second-order finding builders miss: after fabric retrofit the existing gas central heating system became oversized, which reduced its efficiency, though low-cost fixes were found. Energy House 1 is a full-size Victorian terraced house inside an environmental chamber that can replicate outdoor temperatures anywhere in the UK at any point in the heating season.

    A breakdown of the Scottish housing stock drawn from the 2015 Scottish House Condition Survey, covering dwelling types, ages, heating systems, sizes and U-values. Headline fuel split: 79 per cent of the Scottish housing stock runs on gas, 12 per cent on electricity, and oil and other fuels together account for around 10 per cent. Flats, a category that includes maisonettes, two-storey flats and tenements, make up the highest proportion of buildings in Scotland, which is why communal ownership and shared stairwells shape what retrofit is possible there. Semi-detached houses are described as paired by a common wall and designed to use less space than detached; terraces, common in old industrial towns and popular through the 20th century for high density working class housing, share walls on both sides.
