This Executive Summary provides an overview of the findings, observations and recommendations resulting from Kingdom‟s Housing Innovation Showcase (HIS) project. This is based on post construction testing of twenty seven new build homes built using a range of Modern Methods of Construction (MMC). The HIS comprised of twelve flats with communal gardens and fifteen houses with their own private gardens. All of the tested homes varied in terms of size, form and construction technique. New technologies were installed and included Solar Hot Water (SHW), Solar Photovoltaic Panels (PV), Combined Solar Hot Water & Electric Panel PVT Collector, Voltage Optimisation, Air Source Heat Pumps (ASHP) as well as Gas-fuelled Micro Combined Heat & Power Boilers (mCHP). In addition, ventilation strategies were incorporated including Mechanical Ventilation with Heat Recovery (MVHR) and Mechanical Extract Ventilation (MEV) systems. All homes were fitted with an In-home Energy Display monitor. The HIS provided a unique opportunity to undertake post-construction evaluation testing and monitoring in order to understand and evidence the relationship between MMC, the effectiveness of new technologies and resident satisfaction levels.
