Passive and Energy-Efficient Houses

In search of savings, investors more and more often decide to build a house in energy-saving technology. And although the cost of building such a house may be significantly higher than the standard one, subsequent profits from daily operation quickly offset the investment.

What is a passive house?

Passive houses are characterized by very high thermal insulation and low energy demand. With a range of technological solutions, the energy demand of a house is typically below 15 kWh/(m²/year), which is about eight times less than that of a standard house, which consumes up to 120 kWh/(m²/year) per year. In addition, a passive house is built to recover the maximum amount of energy from nature – such as daylight. However, no new and expensive technologies are needed to build them. Passive building is about increasing the efficiency of elements that have been used for a long time. Solar collectors, infrared heating mats and various types of electrical devices are used to obtain the right temperature in passive rooms.

The advantages of a passive house:


The innovative concept in the construction industry allows to build projects with very low energy requirements for heating the interior (up to 80% less energy used).

Intelligent home

A passive building provides comfortable temperature and lighting conditions without the intervention of external energy providers.

Environmentally friendly

The structure, as well as the materials used to build a passive building, reduce losses and energy consumption to a minimum, thus obtaining it from other, natural sources.


A passive house certificate and an energy performance certificate documenting its energy efficiency, increases the price of the house at sale accordingly.

Fresh air in the house

The controlled ventilation system continuously exchanges “stagnant” air, so the humidity level in the house is between 30 and 60%, thus reducing dust and allergens.


During the construction of a passive house, a huge amount of work is consumed by preparations and planning, there is no room for construction defects, and nothing is installed by accident. This translates into fewer renovations and repairs in the future.

Comfort of living

A passive house provides the ability to maintain a constant, man-made temperature throughout the year. Moreover, thanks to the use of thick walls and tight insulation, these houses are also perfectly quiet.


The main idea of a passive house is not about appearance, but about functionality. Therefore, the characteristic features of such a house are: minimalist form, neutral colours, solid walls and appropriate glazing.

Independence from political and legal conditions

A passive building has its own energy supply system, which makes it independent of large suppliers of natural resources such as coal or gas and is not exposed to possible shutdown of such media.

What is an energy-saving house?

An energy-efficient house is a building that will consume as little energy as possible for daily use, i.e. for heating, hot water heating, lighting and powering electrical appliances. At the same time, it will actively obtain energy from renewable energy sources. The energy standard of the house required by law is controlled already at the design stage. What level of energy efficiency a building will actually achieve depends on a number of factors, including the professional conduct of construction works and high care of finishing works. For a house to be distinguished by a sufficiently high energy standard, it should be equipped with additional, cooperating systems and installations, which will increase the savings of its operation. An energy-efficient house is a perfect combination of technology and quality. It proves that man can coexist with the environment without harming it. It is also a way to live comfortably while minimizing bills.

The advantages of an energy-saving house:

Lower heating costs

Heating and electricity bills are much lower than in traditional buildings.

Better energy performance of the building

Compared to a traditional residential building, an energy-efficient house needs 3 to 5 times less energy to heat.

More real estate value in the aftermarket

A modern home that meets the requirements of an energy-efficient home will not lose its value for many years.

Indoor thermal comfort

Proper insulation and the type of heating and ventilation used, as well as the use of renewable energies, make the apartment warm and the operating costs decrease.

Environmental protection

Modern technologies used in energy-efficient buildings reduce CO2 emissions

Important information

18 May 2010 The European Parliament adopted amendments to the directive on the energy performance of buildings. From 2021 onwards, all new buildings in the Union must be nearly zero energy buildings. New public buildings must meet this requirement from 2019 onwards.

Pay at MCAN

The costs of building a passive or energy-efficient house can be covered in 10% by MCAN coins (currently accepted rate: 1 MCAN = 1 USD, which with the increase of MCAN price on the stock exchange will be adjusted accordingly). The rest of the payment will be made in national currency.

Each passive or energy-saving house project is priced individually and requires direct contact with our consultants.

Deciding to pay in MCAN currency you will receive a 5% discount for the entire construction of a passive or energy-efficient house.

Medican LTD will burn (destroy) 50% of MCAN tokens received. The remaining 50% will be frozen for a period of 2 years (for 2 years they will not go on the exchange).


115 sqm enegosive house – cost about 300,000 PLN = 75,000 USD*.

10% MCAN payable – 7,500 USD payable in MCAN at 1MCAN = 1 USDT
The cost of building a house after payment in MCAN is:
75,000 USD – 7,500 USD (payable in MCAN) = 67,500 USD
67,500 USD – 5% discount = 64,125 USD

The total cost of building an energy-efficient house with the payment of 10% of its value in MCAN will be not $75,000 but $64,125.

*the amounts have been simplified as much as possible for the purpose of the example.

Do not hesitate, invest in a passive or energy-saving house today and enjoy a friendly place to live for many years!
