My name is Pavel Biryukovich and AkvilonPro company. Today I want to tell you about about the energy efficient housr project called Sunny, this house has a simple form optimized for location and according to world sides has an optimal slope of the southern slope of the roof to install a solar power plant capacity of 15 kW that can produce up to 16,500 kW / h per year This house is optimally insulated according to the passive house standard The bearing walls are aerated concrete block 375 mm and above it is insulated by the material of the Basf concern Neopor 300 mm thick to minimize all heat losses U heat transfer coefficient for walls 0.083 W / m2 * K coefficient of heat transfer for the roof 0.104 W / m2 * K floor thermal conductivity 0,189 W / m2 * K window heat transfer coefficient 0.74 W / m2 * K This kind of insulation allows this home to consume for all needs including heating, air conditioning, hot water and domestic energy up to 7500 kW / h per year and it is enough for such a house heat pump capacity 3-4 kW of heat output for heating and hot water supply according to this house can not only minimize energy costs but also make money from sales electricity at green tariff about $ 1500 a year depending on your location and your region it happens when you sell energy for the green tariff. Let’s now look at plans of this house. On the ground floor there is a spacious vestibule 4.6 m2 it is a hallway with a comfortable closet make the vestibule the hallway allow very well insulated front door After we undressed we get into the corridor of 5.4 m2 which is combined with the living room from here we can get into the kitchen which can be separated on occasion odor separation partition and the cooking process if needed Also on the ground floor is a large boiler which houses the heat pump, tank heat accumulator heat exchanger for forced-air exhaust
ventilation systems a boiler can be placed to connect the solar system for hot water supply Also on the ground floor is small bathroom with shower and bedroom or study room depending what lifestyle you have who lives with you. The ground floor is comfortable to live in elderly family members Ascending to the second floor we can get there in a spacious bathroom of 6.1 m2 with corner bath a small pantry area of 2.8 m2 and three bedrooms areas 12, 14 and 16 m2 The total area of the house 119 m2 The slope of the roof is arranged as follows to minimize hits the summer sun that heats the room and allow the winter sun get through the big windows and heat the first floor rooms for sun protection of rooms of the second floor external blinds are used which close on occasion Also for additional closure the terrace uses a retractable awning the back of the house with a minimum number of windows that are oriented south. And there is buffer from the cold winter wind The entrance to the house is located on the side facade Through a small porch Friends, please tell us in the comments what you liked about this project What adjustments would you like to make what is missing If you liked this project put Like, subscribe to our channel Contact us for advice and suggestions But see you later, see you in the new videos.
