Abstract

The purpose of this document is to give an introduction to ventilative cooling systems, and guidance on where to find additional information on the design, calculation and maintenance of such systems. This document gives guidance to the design of ventilative cooling systems. The purpose of ventilative cooling systems is reducing cooling loads and preventing/reducing overheating. Ventilative cooling is a solution to achieve resilient cooling and aspects of this is also covered in this document. With ventilative cooling the building is enhanced for climate change (resilience aspect) in regard to energy shortage, availability, etc.. This document is applicable to buildings specified according to the thermal indoor environmental aspects used for human occupancy where production processes don't have a major impact on indoor environment. This document is thus applicable to residential and non-residential buildings. This document will give guidance on how to design ventilative cooling systems, while referring to relevant calculation standards to ensure coherence and no overlapping. In this document can be found different design approaches and guidance at the feasibility phase before going into the actual design phase. This document is applicable to but not limited to: • Mechanical ventilative cooling • Natural ventilative cooling • Hybrid ventilative cooling The interface from ventilative cooling systems to supplementary cooling systems are mentioned and can sometimes also reduce the temperature, but the design of supplementary cooling systems are not part of the normative part of the document. Further the interface from ventilative cooling systems to mechanical cooling systems are mentioned only informatively and are not part of the normative part of this document. Design of ventilative cooling systems commonly considers other aspects like energy use, acoustical comfort, draught, ingress of outdoor pollutants and cleaning and maintenance, though these are not covered in detail in this document. This document only covers temperature control and not moisture control. Heat losses will not be dealt specifically within this document. This document does not cover waterborne and mechanical cooling.
