Defining and operationalising the concept of an energy positive neighbourhood

Abstract

University campuses, residential neighbourhoods and other urban areas have different needs for energy solutions. The formulation and comparison of these solutions demands welldefined concepts and robust decision support tools. This paper proposes the following definition: "Energy positive neighbourhoods are those in which the annual energy demand is lower than annual energy supply from local renewable energy sources. Short-term imbalances … are corrected with national energy supplies. The aim is to provide a functional, healthy, user friendly environment with as low energy demand and little environmental impact as possible." Key performance indicators are proposed along with an 'energy positivity label'. A decision support tool for the long term planning of neighbourhood energy solutions is described which is currently being used to evaluate a university campus in France and a residential neighbourhood in Finland. The research presented extends the limits of current approaches to energy analyses from individual buildings to neighbourhood level. KEYWORDSEnergy positive neighbourhood, key performance indicators, energy positivity label, urban planning decision support tool, university campus, residential neighbourhood.

A novel renewable energy‐based integrated system with thermoelectric generators for a net‐zero energy house

“…The fresh water is needed in all sectors of life from domestic to agriculture. In order to compensate a reasonable demand of fresh water, the process of reverse osmosis (RO) is more suitable as compared to other processes . The investigation of the effects of operating parameters on the performance of seawater reverse osmosis has been carried out in numerous studies .…”

[13][14][15][16] The investigation of the effects of operating parameters on the performance of seawater reverse osmosis has been carried out in numerous studies. [27][28][29][30] The increased temperature of the seawater reduces the viscosity, which in turn improves the permeability of membrane.…”

Visionary scenarios for planning of energy-efficient buildings and neighbourhoods

“…the presented work creates a span between the earlier developed roadmap for energyefficient buildings [3], through the visions of the future energy-efficient buildings and neighbourhoods from the ict (information and communication technologies) roadmap for energy-efficient neighbourhoods [4], until the energy matching framework for energy positive neighbourhoods [5]. the envisaged energy system scenarios are developed further in d4e project using the integrated design and delivery solutions (idds) framework [6].…”

Visionary Scenarios for Holistic Planning of Neighbourhood and Building Energy Systems

“…The presented work deepens the earlier future visions for energy efficient buildings and neighbourhoods from the ICT roadmap for Energy Efficient Neighbourhoods (IREEN) [3], [4] and Roadmap for Energy Efficient Buildings (REEB) [5], and energy matching framework for Energy Positive Neighbourhoods [6]. These envisaged energy system scenarios are developed further with the Integrated Design and Delivery Solutions (IDDS) framework [7], which can support the iteration of future envisioning design solutions and team level communication, with the support from an advanced service platform that includes a BIM server.…”

“…The scenarios will consider foreseeable new technologies, ICT-based information services and business models. The work described in this paper is part of the EC funded project called DESIGN4ENERGY, which focuses on innovative and integrated evolutionary design methodology for energy efficient buildings, which are flexibly connected with the neighbourhood energy system [2].The presented work deepens the earlier future visions for energy efficient buildings and neighbourhoods from the ICT roadmap for Energy Efficient Neighbourhoods (IREEN) [3], [4] and Roadmap for Energy Efficient Buildings (REEB) [5], and energy matching framework for Energy Positive Neighbourhoods [6].
