Utilizing a cool roof is an efficient way to reduce the cooling energy use of a building. Cool roofs, however, may increase heating energy use in winter.
H. Akbari, M.Hosseini
The nighttime ventilation strategy uses the outdoor cold air during the night to cool the building mass. The cooled building mass then is used as a heat sink during the next hot day.
H. Akbari and H.Aria
This research aims to investigate, analyse and characterize the relation between the economic crisis and energy consumption in Greece.
M. Santamouris, J. A. Paravantis, D. Founda, D. Kolokotsa, G. Michalakakou, A.M. Papadopoulos
The present paper deals with the application of 4500 square meters of reflective pavements in an urban park in the greater Athens area.
M. Santamouris, N. Gaitani, A. Spanou, M. Saliari, K. Gianopoulou and K. Vasilakopoulou
Heat island phenomenon rises the temperature of cities, increases the energy demand for cooling and deteriorates comfort conditions in the urban environment.
M. Santamouris
Urban heat island (UHI) phenomenon has been observed in many populated cities located in cold regions (e.g., Montreal in Canada) during summer.
H. Akbari and A.G.Touchaei
Rejection of solar gains is the aim of passive cooling strategies in any type of building and any climatic region. The extent of cool materials usefulness is dependent on the severity of external conditions and internal heat gains.
E. Mastrapostoli,T. Karlessi, A. Pantazaras, D. Kolokotsa, M. Santamouris
We have developed a new evaluation method of “thermal radiative power” (TRP) for investigating the impact of building surface material albedo on urban environment. The simulation system ENVI-met is used.
Y. Wang, H. Akbari
The present study deals with the feasibility of Flywheel Energy Storage Systems (FESS) in several RES-based stand-alone electricity production systems.
G. N. Prodromidis and F.A. Coutelieris
Fuel cells are highly efficient energy conversion systems that have recently gained significant interest in terms of both science and applications.
G. Fragoyiannis, D. Mytakis and F.A. Coutelieris
Heat island which is the most documented phenomenon of climatic change is related to the increase of urban temperatures compared to the suburban.
D. Kolokotsa, M. Santamouris
The need for more energy efficient Heating Ventilation and Air Conditioning systems led to a search for new systems for heating, cooling and ventilation of buildings.
W. Zeiler, K. Smelt and G. Boxem
In a Dutch project the double façade became an integral part of the ventilation concepts aa well as the heating system by trying to optimize the heat gain within the cavity during spring and autumn.
W. Zeiler, J. Richter and G. Boxem
The aim of this paper is to experimentally investigate and analyze the thermal and optical behavior of a Green Roof System (GRS) installed in the 10000 m2 roof of a fully insulated, bioclimatic office building in Peania.
P. Karachaliou, M. Santamouris
Cool roof coatings remain cooler than absorptive roofs and thus predominantly are used in buildings that require the reduction of the indoor temperature and the cooling loads. Cool roofs can also reduce the ambient temperature.
E. Mastrapostoli, M. Santamouris, D. Kolokotsa, P. Vassilis, D. Venieri, K. Gompakis
An urban park located in a densely built area of  Western Athens, Greece is monitored. Temperature data from 15 urban and suburban stations are also used to perform comparative analysis at the city level.
F. Skoulika, M. Santamouris, D. Kolokotsa
Τhe present article deals with the development and testing of photovoltaic pavement for heat island mitigation. The scope of this study is to evaluate its contribution to the balance of the Urban Heat Island phenomenon.
C. Efthymiou, M. Santamouris, D. Kolokotsa and A. Koras
The present article deals with the energy classification and the environmental evaluation of the school buildings in Greece.
N. Gaitani, M. Santamouris
The improvement of the urban microclimate combined with the reduction of the energy loads is a highly important target that requires the research and development of innovative solutions with advanced thermal and optical properties.
T. Karlessi and M. Santamouris
Surface temperature measurements were performed in a deep street canyon, during summer period, in the center of Athens.
C. Georgakis, S. Zoras and M. Santamouris
