Experimental Research of Thermal Comfort Conditions in Small Test Buildings with Different Types of Heating
2015
Abstract The aim of this study is detailed analysis of long-term monitoring data of thermal comfort conditions and energy efficiency in small test buildings equipped with different heating systems. Calculations of PPD index and local thermal discomfort factors are provided for the test buildings during three weeks of heating season. It is shown that the type of heating system has influence not only on heating energy need, but also on thermal comfort conditions in the room.
Multicriteria evaluation of heating choices for a new sustainable residential area
2015
Abstract The city of Loviisa in Finland is planning a new sustainable residential area with a total of 240,000 m2 of residential houses and apartment buildings with services. The city wants to promote sustainable energy solutions in the area, considering various renewable energy forms for heating. The aim of this research is to evaluate which heating system would be best for a new single-family house when different technical, economic, environmental and usability criteria are considered. A group of experts evaluated the alternative heating systems with respect to the criteria. The citizens were involved with a questionnaire to provide preference information for different criteria.

Zastosowanie magazynów ciepła do celów grzewczych i c.w.u
2018
Magazynowanie energii jest kluczowym zagadnieniem dla rozwoju energetyki odnawialnej. W obszarze budownictwa i inżynierii komunalnej, poza innymi formami, zachodzi konieczność magazynowania energii w postaci termicznej, rozumianej jako zwiększenie energii wewnętrznej układu magazynującego lub wykorzystanie przemian fazowych. Technologie wykorzystujące procesy sorpcyjne, lub efekty termiczne reakcji chemicznych są tu raczej mniejsze zastosowanie. Energię termiczną w najmniejszej skali magazynujemy w zasobnikach ciepłej wody użytkowej, w zbiornikach buforowych instalacji grzewczych. Większe instalacje realizowane są dla obiektów użyteczności publicznej, takich jak szpitale, biurowce. Duże mag…
Analysis of Thermal Comfort Conditions and Actual Energy Efficiency for Different Heating Systems in Test Buildings
2015
The aim of this study is detailed analysis of long-term monitoring data on thermal comfort conditions and energy efficiency in small test buildings equipped with different heating systems. Calculations of PPD index and local thermal discomfort factors, as well as actual energy efficiency ratios for different heat pump systems are provided for the test buildings during three weeks of the heating season. It is shown that the type of heating system has an influence not only on heating energy needs, but also on thermal comfort conditions in the room.
Multicriteria evaluation of sustainable energy solutions for Colosseum
2017
Abstract Colosseum is a large office building in the capital region of Finland. The building owner operates on the highly competitive office rental market. With increasing emphasis on environmental responsibility, energy efficiency and sustainable energy solutions can provide competitive edge on the rental market. This study evaluates in terms of multiple criteria different alternatives to enhance the energy solutions of the building. The alternatives included different configurations of solar power, ground source heat, and roof constructions, along with district heating. Decision criteria included internal rate of return, energy efficiency, CO2 emissions, and attractiveness. Attractiveness…
