Abstract

This paper discusses an instrumental approach to design better energy efficient
buildings within the context of neighbourhood, already at an early design phase. In the EU project Design4Energy (D4E) a scenario driven approach was used to define the activities that should take place at an early design stage, as well as the actors involved and the tools required to support such activities.
Six KPIs and a tool were defined to be used in early design phase to support
communication between design team and client. In addition, energy matching was analysed with specific indicators.
The key aspect of the energy matching in districts is balancing the demand with the energy supply from local renewable sources. To assess how well the local renewable supply meets the local demand in the building, a set of new key performance indicators (KPIs) were proposed. These KPIs include yearly on-site energy ratio (OER) and energy mismatch indicators for each energy type (heating, cooling and electricity). The mismatch indicators include annual mismatch ratio (AMRx), maximum hourly surplus (MHSx), maximum hourly deficit (MHDx) and monthly ratio of peak hourly demand to lowest hourly demand (RPLx), where x is replaced by an indicator for the different energy types respectively (h for heating, c for cooling, e for electricity). The new indicators are used in different stages of the design process, but they are particularly useful at its early stage. The use of indicators is extended from building level to cover the neighbourhood context.
This paper discusses the methodological approaches, demonstrates how communication between design team and the client can be facilitated using KPIs in different phases and presents specifically how relevant indicators help to achieve possibly high level of sustainability and energy efficiency in the neighbourhood.
