The paper presents an intelligent building (IB) development strategy emphasizing the locally available non-polluting renewable energy resources utilization. Considering the immense complexity of the topic, the implementation strategy of the main energy-flow processes is unfolded, using the net zero-energy building concept (NZEB). Noticeably, in the first research steps the mathematical background of the considered NZEB strategy has been developed and presented. Then careful LabView software-based simulations prove that the adopted strategy is feasible for implementation. The result of the above mentioned research efforts is a set of powerful and versatile software toolkits well suitable to model and simulate complex heating, ventilation and air-conditioning processes and to perform energy balance performance evaluations. Besides the elaborated mathematical models, concrete software implementation examples and measurement data also is provided in the paper. Finally, the proposed original models offer a feasible solution for future developments and research in NZEB applications modelling and simulation purposes.

Abstract As it is well known that due to the continuously decreasing trend of the alternative energy technologies and the increase in the costs of the traditional fossil fuels, the development of resident or commercial buildings with greatly reduced energy needs becomes a high ranked and more pressing scientific challenge. In topic with this technological and scientific provocation, the paper presents a LabView software-based building supervising and events monitor system designed and developed with the basic purpose to serve as support for net zero-energy control strategies implementation in intelligent buildings. Afterwards a brief presentation of the adopted intelligent building development strategy and the net zero-energy concept are presented and discussed. Once these theoretical aspects have been expressed and clarified, a multi-layer type implementation is unfolded, where the background layer is a building supervising and events monitor system. The main software development steps of this system are presented in details to prove the feasibility and reliability of the adopted implementation strategy.

Controlling air leakage through the building envelope remains a challenge, especially in light of the imperative to transition to a net-zero energy building sector and the increasing importance of indoor air quality during extreme weather events such as wildfires. The British Columbia Energy Step Code is a performance-based compliance option in the British Columbia Building Code which is intended to provide a transition pathway to net-zero energy ready construction by 2032. For small residential buildings, performance targets entail thresholds for the measured air leakage rate through the building envelope. This paper reports on the airtightness of the first 145 single- and two-family dwellings built under the Energy Step Code in Richmond, BC. Although the first phase of the implementation of the Energy Step Code in Richmond entailed no airtightness targets (only testing), results indicate improvement compared to the historical levels of airtightness in the region.
