Passive house for Latvia. Energy efficiency and technical-economic aspects.
(2010)Department of Energy Sciences
- Abstract
- The growing energy prices and energy consumption caused the interest about buildings
with low energy consumption such as Passive house. Energy demand in households
accounts for around one forth of the final energy needs in the EU (Intelligent Energy
Europe 2006), and it is a potential for energy demand reduction. At the same time,
environment protection with a reduction of CO2 emissions nowadays is becoming a
requirement for new built buildings. European Union tends to implement Passive house
standard in 2016. And in many countries, including Scandinavian countries, there is a
good experience of Passive house whereas in Latvia this concept is new at this moment.

standard in 2016. And in many countries, including Scandinavian countries, there is a
good experience of Passive house whereas in Latvia this concept is new at this moment.
The main objective of this work is to explore what a Passive house is, to find out the
energy efficiency requirements for it and to study technical-economic aspects of it.
Another objective, as a personal input into this work, is to design ventilation system for
Passive house in Latvia and to compare annual costs for heating for Passive house and
standard Latvian house.
Theoretical part of the work is based on available literature that includes study of articles,
publications and thesis works that are carried out in field of Passive house. In addition, to
deepen literature study, consulting with specialists and researchers working with this
issue is done. In practical part, all calculations are done with traditional calculation
methods and calculated in Excel software, in order to see it in detail. No design software,
such as CADvent or MagiCAD, is used.
At the beginning of the theoretical part of the work, the concept and definition of the
Passive house are described, the late history of Passive house is presented, the overview
of other low energy building types are done and the benefits of Passive house are studied.
Afterwards, the view of energy efficiency requirements for building envelope, heating
system, domestic hot water, ventilation and air conditioning, lightening and equipment,
location of the building, indoor climate and energy use of Passive house is done. This
part includes also maintenance, standard and examples of Passive house. In the last part
of the theoretical work the technical-economic aspects of Passive house are studied.
In the practical part of the work, ventilation system for Passive house in Latvia is
designed. The heat losses of the building are calculated and added to ventilation system
in order to obtain heating with ventilation system. Principles of Passive house are applied
for one specific building as an alternative of standard applications. Building is not
designed as Passive house initially. Additional part of practical work is calculation and
comparison of annual costs for heating for Passive house and standard Latvian house.
The overall conclusions of this work, on the introduction of Passive house in Latvia, are
that Passive house is specific type of the building that requires proper planning, design
and construction. From economic point of view, Passive house justification is influenced
by many factors, mainly by energy price; Passive house usually do not have active
heating system, instead ventilation system is equipped with function of preheating supply
air. Ventilation system of Passive house is more complicated and very important in
design compared with standard building. (Less)
