Energy Environment & Sustainable Development Thematic Network on Energy in the Built Environment TRIPLESAVE JOR3-CT PROJECT OBJECTIVES The project aims to develop a unit combining light pipe technology and passive stack ventilation by utilising the light pipe as an exhaust stack. This system is further integrated with two different energy options, either for heating or for cooling.

Energy Environment & Sustainable Development Thematic Network on Energy in the Built Environment TRIPLESAVE JOR3-CT CONCLUSIONS the developed LVP concept seems to function satisfactorily a static collector seems not to be the right concept for the LVP the profitability of the LVP varies from country to country a major potential for applying the light- vent pipe seems to be in schools and offices the LVP concept as a whole is not finalised yet and needs some additional development
