Rooftop photovoltaic (PV) power generation stands as a promising technology for the transition towards a low-carbon power and buildings sector. However, in the past deployment has been strongly dependent on policy support. With the recent rapid decrease in module costs, rooftop PV is exhibiting...

The built environment contributes around half of total greenhouse gas emissions and with 87% of residential buildings that we will have by 2050 already built, it is vital to adopt sustainable retrofitting practices. The question is: what are the viable solutions? One answer may be green roof...

A transformation of prevailing energy systems requires adequate measurement systems. In this paper we propose an energy-service based indicator set and a composite index for monitoring sustainable energy development in the residential sector and electricity and heat supply in Austria. The system...

Ground source heat pump (GSHP) systems exhibit high thermal performance. Consequently, they are increasingly used to heat and cool buildings. The thermal performance of GSHP systems strongly depends on the operation ground temperature and thermal quality of the building envelope (TQBE). The...

The Energy Performance of Buildings Directive (EPBD) recast imposed on all Member States to establish representative reference buildings as an important step in drawing up a methodology for calculating cost-optimal levels of minimum energy performance requirements for buildings and building...

The energy demand in building sectors for summer air-conditioning is growing exponentially due to global warming, increased living standards and occupant comfort demands throughout the last decades. Concerns over these environmental changes have begun shifting the emphasis from current cooling...

Electric utilities, government agencies, and private interests in the US have committed and continue to invest substantial resources – including billions of dollars of financial capital – in the pursuit of energy efficiency and conservation through demand-side management (DSM) programs....

The paper brings new evidence on the impact of separate mechanical ventilation system on the annual energy and exergy performance of several design alternatives of residential heating systems, when they are designed for a house in Montreal. Mathematical models of residential heating, ventilation...

The extensive energy use in the European building sector creates opportunities for implementing energy conservation measures (ECMs) in residential buildings. If ECM are implemented in buildings that are connected to a district heating (DH) system, the operation of DH plants may be affected,...

Throughout the last years the use of on-site renewable energy sources (RES) in residential houses has continuously increased in many industrial countries and it is expected that many of the supply systems will be based solely on renewable sources in the medium term future. However, the...
