Interventions moved on to the second test site, this time looking at the impact of varying levels of room air carbon dioxide. During the intervention CO2 concentrations range from extremely high, down to industry gold standard, with each condition maintained for a number of days. The use of temporary fans with control independent to the buildings main ventilation system enable close control of the CO2 concentration within 100-200ppm.
The intervention stage begins. To start the interventions are looking at how occupants respond to temperature changes. The interventions will be tweaked throughout with a shift in emphasis every four weeks. In November interim project results presented at CMS in London.
The baseline testing is now complete. Hundreds of participant responses have been collected, along with IEQ data spanning across the end of winter, spring and summer. Over this period we have seen extremes of both temperature and CO2 concentrations, along with a host of other interesting data. The next phase will help to understand what impact these conditions are having on the building occupants.
Testing is underway in both case study sites. Early data on indoor environmental quality shows some interesting results, and information is now being collected from the building users on their views of the working environment. In total more than 500 people are accommodated within the trial areas.
Two trial sites have been formally selected and reviews conducted to understand what is possible with the existing M&E installations. The two sites vary considerably in both location and design, although both are large open plan office spaces housing more than 100 staff in each area. Sensoring requirements have been identified and appropriate solutions are being sourced.
Quarter 2 of the project finished at the end of July 2016. Trial buildings have been provisionally identified and a scoping framework devised to assess suitability for the research. Specifications for measurement are now complete and include technical, business and user data.
Quarter 1 of the WLP+ project finished at the end of April 2016. During the first 3 months Oxford Brookes University completed an interim report reviewing the literature covering productivity and indoor environmental quality. Outcomes from this work informed the specification for recording data from the WLP+ trial buildings, with the development of the specification taking place during Q2. Other developments in Q1 included the launch of the WLP+ website and presenting at the FMP Event.
