This thesis focuses on zone based climate control in pig stables and how to implement climate controllers in a new range of products. The presented controllers are based on simple models of climate dynamics and simple models of actuators. The implementation uses graphical point and click features from the Mathworks' range of products andautomatic code generation. It is furthermore shown how to build new climate control systems based on cheap and readily available hardware and software. An early result for performing system identification for zone based climate dynamics is also presented. The thesis is a collection of eight papers. The first two papers deal with the mplementationof controllers and how to integrate the development of controllers into a complete framework that can provide different services e.g. remote monitoring. The same framework is also capable of automatically generating source code for the actual target platform, on which the climate controller is expected to execute. The third paper also deals with the development cycle of controllers, showing how to build a graphical user interface for point and click modelling of zone based climate dynamics. The next two papers present an early result for performing system identification for zonebased climate dynamics, based on an idea of guaranteed internal flow directions. Paper 6 presents a verified stable distributed temperature controller for pig stables divided into zones. Paper 7 is an expanded journal version of paper 6. Paper 8 presents a distributed temperature and humidity controller based on the ideas presented in papers 6 and 7, but where the controller synthesis is done automatically via a presented tool chain
