Rowner Research

Background

Rowner Renewal is the £145 million regeneration of Rowner, Hampshire.

 

Zero Carbon Hub, working closely with First Wessex and a number of stakeholders, considered this site to be a unique opportunity to test for the first time the practical implementation of the Fabric Energy Efficiency Standard (FEES) in flats. The project was funded by a Technology Strategy Board scheme, the Building Performance Evaluation (BPE) programme and was also co-funded by the different stakeholders.

The project started in 2010 and has been running ever since. This BPE project investigates the performance of two blocks of flats, 12 flats in each, one designed to the Fabric Energy Efficiency Standard (FEES) and the other to Code for Sustainable Homes (CfSH) Level 3.

The Research Project

The Rowner research project consists of three distinct phases.

Phase I - Post Construction / Initial Occupancy (2010 - 2011)

As FEES had only just been introduced, the Hub helped devise the strategy for how this could be achieved. This phase followed the construction on-site, from day one to the early handover of the flats to the residents. It included interviews with the different teams involved in the construction process, energy prediction modelling, photo documentation of the process, advanced testing of the fabric and surveys.

 

Phase II – Post occupancy evaluation (2011 - 2013)

This phase gathered information in regards to a wide range of parameters which can impact internal comfort, occupancy patterns and analysis of trends of gas, water and electricity consumption. The difference in energy consumption between the two blocks was also investigated.

 

Phase III - Overheating Study (2012 - 2013)

Running in parallel with the second year of phase II, the overheating studies analysed in more detail data gathered from advanced monitoring of a number of flats to evaluate the potential of overheating occurring in highly insulated buildings. Along with temperature and humidity, the window opening and closing trends were also monitored.

 

Summary

The research project at Rowner looks into all these aspects and the research can be broadly explained in terms of:

  • Testing and analysis of building fabric.
  • Evaluation of design intent and site practices.
  • Analysis of operational efficiency of fixed building services.
  • Evaluation of handover and occupant engagement.
  • Analysis of post-occupancy fuel and resource consumption.
  • Evaluation of internal environment and comfort.
  • Occupant satisfaction.
