Improvement measures adding energy efficiency to the house in Aylesbury include vastly improved insulation [new doors and windows as well as new insulated internal linings], roof-integrated photovoltaic panels by Viridian Solar and an exhaust air heat pump that captures internal heat gains in the stale air before it is expelled and replaced by fresh air. In summer ventilation and cooling is to be achieved by opening the windows. The basic monitoring package from BSRIA Instrument Solutions consists of three internal and one external temperature and humidity sensors, a carbon dioxide sensor in the main living space and a data hub where the information is accumulated. Additionally in Aylesbury there are two sensors monitoring the supply and extraction sides of the mechanical ventilation heat recovery [MVHR] system, two pyronometers measuring light levels on the different roof planes where the solar panels are situated, heat flux measurements on the solar heating and the hot water system and seven electrical sub-meters covering input for lights, MVHR and PV solar pumps.
At the end of the two year period the monitoring system will have provided invaluable statistics on the extent of energy savings achieved by the various systems used in the house, which will be evaluated not only by the TSB, but also such bodies as the Energy Saving Trust (EST) and myriad commercial interests in the construction industry. BSRIA Instrument Solutions are so far committed to supplying fifty-three basic testing packages to the TSB, most enhanced by additions tailored to individual requirements. The total number of homes to be monitored is 86 with a time scale extending into 2013.
BSRIA provides monitoring instruments such as the Radio-Tech Wi5 wireless data collection system and independent Building Performance Evaluation services. For more information contact BSRIA Instrument Solutions:
