Nearly zero energy building in Tartu

Most energy efficient prefabricated building of the year 2017. Awarded by the Estonian Woodhouse Association.

This house is an example of utilising compact design and renewable resources, making it a nearly zero energy house. There is an array of 21 photovoltaic panels on the roof with a peak power out of 5,5 kW. Most of the energy efficiency is achieved with minimised heat loss (measured air-tightness at blower-door test is n50 = 0,21 h 1/h) and maximised solar gain (big windows towards the south and highly transparent glazing).

The house is surrounded with pine trees and thus the exterior design uses dark timber cladding and plaster with light cladding as an accent. Although the house is prefabricated, there is a wide variety of exterior design options.
