Nigel Ingram continued with a discussion about social housing and the consideration of end users when designing buildings. The Joseph Rowntree Housing Trust currently looks after 2,500 homes in Yorkshire and Hartlepool. Nigel discussed one particular project the Housing Trust are involved in, the Derwenthorpe village which looks at the lessons learnt from past projects and how they can improve their buildings. The way the Joseph Rowntree Housing Trust decided on best building practices was through experimentation over four years, they built two prototypes and used 17 different methods and as many M&E components as possible including greywater harvesting and block work systems. The aim of this experimentation was to see what worked to create the best possible building.
As well as all these design considerations Nigel also enforced the importance of the end user and their lifestyles with the Joseph Rowntree Housing Trust looking at how people live in buildings and what changes in lifestyles are expected in the future and how best can the prepare buildings for that. There were three main points that made up their strategic servicing infrastructure, the first being fibre optics. The Trust believes that with the use of technology ever increasing including internet, television packages etc. they needed to invest in a viable cabling network. However none of the big companies were prepared to discuss such a project therefore the Trust developed a joint venture with an investor to set up their own fibre optics for the estate, by doing so they satisfied the customers and set them up for any increase in connectivity in the future.
The second point the Trust considered was Communal Heating, they looked at a variety of different heating techniques for the estate such as low ground source heat pumps. Communal Heating was decided on in 2007 from a carbon footprint point of view as at the time the Code of Sustainable Homes was announced with zero carbon targets by 2016. Communal Heating is notoriously difficult to get working efficiently, just like any heating system however after it was distilled down into the six components that worked for the Trust it was able to provide fuel security and prince control for the future residents which is what users wanted from their buildings. The system now works and is one of the only systems in the country that is successful and has been contracted for 25 yrs to a European Communal Heating group.
However Nigel wanted to point out that the Derwenthorpe village has not been completely successful, the final point in their strategic servicing infrastructure was MVHR Systems. The project has not seen any success with these systems, it has been installed in 64 houses but customer feedback has been negative and there are many issues with it. As an alternative MEV is now being used. Nigel stresses that there is a market for MVHR systems but for it to work there needs to be massive improvements in the industry in terms of commissioning, installation and maintenance. There seems to be a technology focus rather than process and this needs to change if the industry is to satisfy clients and users of buildings.
Nigel’s main focus for the Derwenthorpe project was customer satisfaction, the importance of the end user. Fibre Optics and Communal Heating was installed for the benefit of the residents of that estate as they have certain expectations of the way they live including operational and financial. The Joseph Rowntree Housing Trust has focused on the end user for their design plans rather than what should work from the industry perspective. Rigorous testing and accepting systems aren’t right has gone into making sure buildings are built as best as they can be which is important for our industry, it’s taking into consideration the mistakes made on previous building stock and learning from them and also considering the occupants and their needs.
