Strategies for design and control of buildings

Subtask 4: Strategies for design and control of buildings

Definition
This subtask will apply results of previous subtasks of the Annex together with existing state of the art knowledge to devise optimal and practically applicable design and operation strategies for high IAQ (Indoor Air Quality) in residential buildings.

The strategies will take into account requirements for IAQ based on national building codes and international standards as well as newly developed metrics. Optimal strategy is understood as one that takes into account building energy performance, user comfort and health conditions. It is intended to create a matrix of different possible strategies, based on experience of the Annex 68 participants that enables evaluation of possibilities for win-win solutions (excellent IAQ at low energy consumption) as well as other alternatives that will ensure high IAQ.

Deliverables
Subtask 4 aims to deliver a guide on design and operational strategies for optimal energy performance and high IAQ in residential buildings. The guide will be addressed to designers, building operators as well as owners to help them identifying the best IAQ strategy for their building.

Recent activity and future steps
The subtask consists of the four main activities. Their time plan is presented in the table below:

Currently a survey investigating relations between building code requirements and everyday reality of stakeholders involved in design and operation of residential buildings is being conduced. The survey has two main objectives, firstly, to describe and analyse a transition between actual requirements (national building codes and standards) and current practice. Secondly, to investigate current barriers and challenges regarding installation of mechanical ventilation in residences. In total, 35 interviews from six European countries and China have been analysed, certainly not enough for a representative sample. However, the results provide a valuable snapshot of current practices and insights into potential barriers. The results are going to be presented at 8th AIVC - 6th TightVent & 4th venticool Conference, 2017 (Ventilating healthy low-energy buildings, 13-14 September 2017, University Of Nottingham, Nottingham, UK) and the paper published at the conference will be available shortly after the conference.
