The aim of this case study is to investigate an integrated heating/cooling system performance in central Europe climate conditions. The possibility of a reliable application of radiant low-temperature heating/ high-temperature cooling ceiling system with capillary mats is discussed. ESP-r, an energy performance simulation program, was used for this purpose. Three types of the buildings are taken into account: a residential building, an office building with small offices and an office building with open space offices. Each of them represents a different operating pattern.

The Lyon Confluence project is an actual urban planning operation of Lyon agglomeration. It is part of a global sustainable development process, mixing economic development, social equity and preservation of natural resources.

This paper demonstrates how variations in the estimation of internal gains due to usage affect the cooling demands of speculative office buildings.

The performance of an innovative floor heating application is explored. A two zone building is studied; one zone is frequently overheated due to intensive solar gains while the second zone is essentially unaffected from incident solar radiation. The aim is to explore the possibility to simply extract excess heat from the overheated zone. The idea is to transfer extracted heat through the hydronic floor heating pipe to the second zone; hence, the heat demand for the second zone is decreased. Simulation results yielded a reduced indoor air temperature in the warm zone.

The effects of groundwater direction on performance of geothermal heat pump systems were analyzed using a 3-D finite difference method with rectangular meshes. Each borehole was approximated by a square column with the actual circular borehole section circumscribing the approximated square section. The fluid temperatures inside each borehole were calculated by discretizing borehole vertically into different segments.

An economic and environmental analysis on residential internal combustion engine (ICE) based cogeneration in Canada was performed. Information from three publicly available databases was used to model four houses to be used in simulation. One house per Canadian region was chosen and modeled in ESP-r. Annual simulations using the existing space and domestic hot water heating equipment were performed and these base case results were compared to the results using the ICE based cogeneration system.

Large, multi-use sports and recreational facilities provide a unique, yet challenging, opportunity for energy conservation due to their large process loads. The proposed paper describes the use of building simulation to aid in mechanical system and architectural design to improve heat recovery from process heat generation to satisfy building loads. The focus of this study is a recreational facility that consists of an NHL-size ice arena, 8-sheet curling rink, a gymnasium, change and restrooms, offices, library, fitness studios, a large glazed atrium, as well as 50 metre lap, leisure, outdoo

The present paper is an attempt to bridge the gap between building designers and simulationists by proposing a common framework for discussion. It is a positional paper written from a building designer’s viewpoint that basically agrees with the proposition that design is no longer dominated by physical structure thinking but by performance and system based concerns.

This work presents energy and exergy comparison of several design options for combination between dwelling ventilation and domestic hot water production. The dwelling ventilation uses mechanical exhaust with natural air supply (without heat recovery) or balanced ventilation with heat recovery. The outlet ventilation air is used as a heat source for domestic hot water, by using a heat exchanger or a heat pump.

The last object of this study is to develop standard method for building insulation performance on-site evaluation using Infra-red camera.
