Passive House: Maintenance about 100 Euros per year

An investment by 10-15% higher than for a conventional housing reduces maintenance costs.
Passive house does not look like a matchbox, but can be as attractive as a traditional or modern building.

In the case of an ordinary house, annual maintenance can reach an average of 450 Euros a month. In the case of a passive house, these costs do not exceed 100 per year. Digits, say experts, are available for homes heated with gas. Summer costs are reduced because it is not necessary to use the air conditioning.

Energy consumption for a passive house is 80% lower than for a building constructed of masonry or wood. It is a perfect sealed house, thermal transfer zero, the desired thermal equilibrium and keeps it easily with low energy consumption. In fact, this type of buildings represents a concept of eliminating the harm caused by a construction, energy savings and substantially reduced maintenance costs.

They do not rise in only few days, from prefabricated alternative materials, and do not have a pre-standardized architecture that can be moved anytime and anywhere.

Passive houses are built of common materials, but by complex calculations and heat insulation, they manage to eliminate the transfer of energy with the environment. Therefore, the inside of the house reaches a predetermined thermal equilibrium, averaged between 18 and 22 degrees. While a normal house can be energy loss that occur through thermal bridges, gaps in the “resistance” to heat the house, which usually form in joints, in areas of penetration of the pipes, a passive house acts like a thermos . Energy consumption is so small that it may consider alternative energy like solar energy, provided by solar panels accessible today both in price, as well as availability.

However, a constant element in the equation is the three rows of the windows’ glass. Another feature of passive houses is the vapor barrier, which prevents condensation of the walls. Thermal insulation is calculated so that the outdoor temperatures do not affect indoor micro-climate, even in hot season, even in the cold. Therefore, in such case, no condensation ever forms. Warming is achieved with air ventilation, no gas or coal, heat being recovered also through the ventilation system. Energy consumption is up to 80% lower compared to a house warmed with traditional resources.

No passive house does look like any other, because it is projected for each case, depending on many variables.
