This is a project for a dance shed, trying to be as greenest as possible.

 

The selected materials are stone, wood and polycarbonate.

 

A hardwood sprung floor will help to better dance.

 

The shape of the building is designed to collect as much sun energy as possible.

A geothermal system will give comfort to the building. It would be a good idea to use an air-ground heat exchanger, instead of a geothermal heat pump. In winter time it would provide a 4C to 5C over the average temperature and a bit more in coldest days. That may seem few, but it is a lot of saving in heating bills, and installation is much cheaper than a Geothermal heat pump.

A 30 m long 200 mm in diameter pipe will be installed under the shed at 1 meter in depth. The lack of heat in winter time should be provided with electrical or gas heaters. In summer no further requirements will be needed.

 

The shed will need also a ventilation system and probably a rolling shading fabric cover, over the polycarbonate roof, to make it comfortable on the hottest summer days.

 

The side walls will have the ventilation and “air-conditioning” system built in, so by opening and closing manually a couple of outlets, you will be able to control temperature.

 

The glass doors on the front side could be built with a glass/mirror system so it allows to turn them into large mirrors when needed or leave them as see-through doors.

 

The coating to do that is usually installed the reflecting side facing out. In that case, installing the reflective side facing in will increase the greenhouse effect, which is good in winter and because the doors are facing north will not increase the temperature in hot weather if the shading roof is used.

 

A curtain hanging along the shed will divide the space to have a more private place to change clothes.

 

Toilet would get the water from harvesting rain falling on the roof, and filter it through gravel and sand, which would make it clean enough to wash hands and flushing the toilet but will not be drinking water.

 

Electricity should be connected to the main building.

 

The back wall of the building would have a built-in storing space. So would be the water tank.

 

 

Those are the geothermal data.

 

The average temperatures measured at different depths on Jan 9th in London were

surface             2.50 degC
1m deep            6.93
2m deep            9.87
3m deep           11.12
4m deep           12.00
5m deep           12.25
5.45m deep       12.25

Based on this data, the gradient suggests that the ground temperature has stabilised at about 5m, but that the gain in temperature from going deeper with a horizontal collector (e.g. 2m rather than 1m) would be appreciable.
