<textarea id="source"> # Image Gallery The next pictures show the construction of the solar house from the very first beginning.  Next is the 24000 liter tank used for energy storage. --- ## Tank used for latent energy storage The 24000 liter tank has a dimension of 2.4 m diameter and 5.5 m length, the inside has an anti corrosive covering. --- ## Installation of the latent energy storage tank The tank is buried vertically at a depth of 7,5 metres without insulation to allow a cooling heat outflow during the summer and inflow of enery from the ground during winter. --- ## Basement space --- ## Drainage and underground Piping --- ## Flattening for the ground insulation placement --- ## Ground insulation placement Using 8cm + 6cm WLG 032 Styrodur insulation --- ## Completed ground insulation --- ## Basement floor armoring --- ## Completed basement floor Note the double armor for the walls with a moisture seal in between. --- ## Basement Walls 24cm thick basement walls are poured in a 30cm casing lined with 6cm insulation. --- ## Completed Basement Walls The walls are of impermeable armored cement. --- ## Basement inside walls --- ## Heat exchange tubing tower The heat exchange tubing towers of 5 meter tall and 50cm diameter, to be placed in the latent energy tank. --- ## Heat exchange tubing in the tank Ten of these are fitted in three rows honey-comb-like with a pattern of 3, then 4 and again 3 towers within the tank. --- ## Looking down into the tank Looking 5 meters down into the tank with the fixated heat exchange tubing towers. --- ## Heat-excahnger connection to the house The heat exchangers are connected in parallel and checked with air preasure. --- ## Two meters below the ground --- ## Finishing the basement cealing The cealings carry tubing for the wiring and the airing system. --- ## Basement complete The walls have been doubled-up to 14cm of insulation and protected with a drainage matt against the gravel filling. --- ## Insulating Walls The walls are made of sturdy 42.5 cm thick clay bricks with inside insulation having a total thickness of approximately 25 cm! https://www.kellererziegel.de/produkte/x-serie/zmk-x65/ A robust first row of bricks carry the outer weight above the insulation onto the concrete basement. --- ## Ground floor growing --- ## Ground floor completed --- ## Upper floor growing --- ## Ring armor below the roof The top of the wall on the upper floor is topped with an insulated and armored cement ring to carry the roof. --- ## Gable with insulated bricks The walls of insulated bricks continue until the gable. The bricks are precision cut to fit the roof. --- ## House is now shaped --- ## Moisture barrier The roof is covered with a moisture barrier, since the side roof have a verly low angle, also the construction wood is sealed. --- ## Roof construction --- ## Roof shell from above --- ## Roof covered with 6cm outside insulation --- ## Inside the roof --- ## Roof ready for solar panel installation --- ## House is covered! --- ## Other beautiful view of the house --- ## Solar panels intalled on the east side --- ## Insulated Shaft An insulated Shaft goes down from the roof to the basement for the solar energy tubing and wiring. --- ## Solar tubing connection from the inside --- ## Solar tubing connection from the outside The pipes are connected in a return reverse system ("Tichelmann-system" with same distance and same pressure drop, enabling a balanced flow rate). --- ## Hybrid solar panels installation on the west side --- ## Finished west side roof with embedded hybrid solar panels --- ## House front with windows --- ## Windows The windows use insulated triple-glas and an outside aluminum cover. --- ## Exterior rendering --- ## Floor heating preparation The foor heating is installed over 6 cm of thermal and footfall sound insulation. The tubes are clamped onto the depicted frame. --- ## Floor heating tubing --- ## Inside roof insulation On the inside the roof is covered with 24cm of insulation (with the outer 6cm wood fibre boards this makes 30cm in total!) --- ## Inside heat storage tank The basement houses a 1000 liter heating water tank, insulated with 18 cm WLG 032 stone fibre. --- ## Enclosed heat storage tank --- ## Heat pump --- ## Electrical fuse box and distributon Also seen is the 6.4 kW solar battery --- ## Solar inverter --- ## Finished house meets nature --- ## Energy certificate The house far surpases passive house standards. --- ## Winter The superb insulation guarantees comfort and low energy consumption even in the coldest winters. --- ## Energy Prize The low energy solar house concept was selected as a finalist in the 2018 Stanrberger energy prize contest. --- ## Yearly consumption statistics The solar panels producted in the first year more electricity (8160 kWh) than the house pulled from the grid (6370 kWh). It consumed 4960 kWh of its own produced electricity and sold 3200 kWh into the grid. The battery buffered 1726 kWh, taking the electricity produced at daytime into the night. The yearly total energy consumption of 11330 kWh is allocated to 3230 kWh for heating (this is very low!), 4000 kWh for the warm water used by 6 people in the house and 4100 kWh on electrical appliances. --- ## Energy Schema Next is a simplified schema of the energy system of the house. --- ## Energy Plot The produced and consumed energy is recorded and plotted by the Varta system. --- ## Summer Low energy houses can be built with utmost attractive apperance! --- ## Pond Later a pond was added for the pleasure to be at home. </textarea> <script src="http://remarkjs.com/downloads/remark-latest.min.js"> </script> <script> var slideshow = remark.create(); </script>
