‘Pop up’ homes developed to provide affordable housing at low cost
ZEDpods are a new concept in prefabricated housing which can be quickly installed over vacant spaces such as car parks and not require land acquisition or major capital expenditure.
The pods are constructed off site and can be erected in a matter of days with a forklift. They have a patented raft foundation that exerts no more pressure on existing tarmac than a conventional vehicle. They are more cost effective than purchasing land and building conventional construction with conventional foundations.
The Pods are built to higher standards than conventional homes with superinsulation, vapour permeable draught proofed construction, heat recovery ventilation, aluminium clad triple glazing, hot dip galvanised structural frame with timber infill panels and external insulation.
The external envelope is designed to be around 20 years to first maintenance, and is constructed from fireproof, durable and robust materials.
They are designed for assembly on land outside of the development plan such as public parking spaces, vacant lots etc. They can be located to utilise the benefits of car parks such as good transport links, work place locations, in situ local amenities.
As social housing the concept enables Local Authorities to build affordable homes without the need to find land or capital expenditure.
The ZEDpod is a unique kit of parts concept that does not rely on one centralised factory. Pop-up assembly sheds can be set up locally to meet housing demand and create local employment. One ZEDpod home would require 5 public parking spaces. The car park still provides income to the carpark owner with minimal loss of parking spaces.
The ZEDpods are net zero carbon, and use integrated roof mounted solar panels to charge a LIPO4 battery store that often means they only need to connect to the grid for 30 % of the year – mostly in midwinter when offshore wind-powered electricity is often available.
By superinsulating the Pod and providing heat recovery ventilation and high standards of draught proofing, only very small amounts of space heating are required to be comfortable. The biggest heat demand becomes domestic hot water, and this is met by a tiny 400watt electric evaporator plate heat pump. This heat pump works like a fridge in reverse, and circulates its refrigerant through an absorber plate fitted to the upper roof. No fan noise is heard.
One unit of solar electricity will normally produce around 3 units of heat, enabling each home to be substantially powered by solar electricity generated by the photovoltaic roof panels. The solar electricity produced during the day is stored in a large 60kwh lithium ion phosphate battery store with integrated inverter, which can power the homes at night.
On the rare occasions when solar radiation is low in mid-winter, the battery store automatically trickle charges itself during the day from the street light circuit. This avoids spending scarce funds on digging up the car park to install new electricity supplies.
Is COP23 ignoring the carbon emissions involved in constructing buildings?
In fighting climate change, much has been said about energy efficiency in buildings. What about the carbon emissions involved in constructing buildings in the first place, asks Francesco Pomponi., an expert on embodied carbon at Edinburgh Napier…

COP23: Targeting cities can make biggest contribution to climate change
At this week’s climate conference in Bonn, Germany, the pressure is on many national governments to continue implementing the Paris Agreement despite the United States’ intention to withdraw. But they’ll have help from the world’s cities. The COP23…
