  • Solar photovoltaic systems in Swedish cooperative housing (completed)

    Rapid declines in the cost of solar photovoltaic modules have made rooftop mounted systems economically interesting in Sweden, especially large scale systems for multi-family housing. This project seeks to understand how solar PV can technically and economically integrate into the residential cooperative's energy system.

  • Building state-of-the-art (SotA) supermarket: Putting theory into practice

    This project will apply the knowledge accumulated through the research in supermarket energy systems by building a unique demonstration case study is built where today’s most efficient, environmentally friendly and cost-effective supermarket will be designed, installed, monitored, thoroughly evaluated, and well documented.

  • Data driven lab for building energy systems

    A database, which contains operation data from more than 4000 heat pump installations throughout Sweden, can be potentially exploited by end user applications to allow manufacturers, utilities, customers or third parties to perform data monitoring and analysis. However the database suffers from incompleteness, inconsistency, lack of accuracy or sensor calibration issues. To appropriately utilize the database, we will integrate other sources such as models and lab measurements to turn the low quality data into useful information. We will develop a data-driven lab which will act as a virtual platform to improve the control strategies, fault detection and performance degradation.  

  • Digitalization and IoT technologies for Heat Pump systems

    In the last decades digital technologies became widely used in energy end-use sectors and digital solutions have been driving dramatic changes in the society. In the years to come, Heat Pumps will become connected devices participating in the Internet of Things (IoT).

  • Accelerating innovation in buildings

    The research aims at identifying and overcoming problem areas that hinders innovation in the built environment. Also whether current governance structures regarding planning, production and operation of buildings promote change and innovation.

  • Creating and Understanding Smart Innovation in Cities

    This project aims to identify the key factors regarding Cleantech innovation creation and the understanding in how the innovation process for Cleantech works in an urban environment.

  • Toward Sustainable (Fossil-free) Heating System in Small Residential Buildings

    As a growing technology, the number of installed heat pumps in Europe was increased by 60% between 2014 and 2018, and European Heat Pump Association expects a doubling in the heat pump market by 2024. It is therefore a high priority to further increase the share of renewable sources in the heat pump’s configuration to increase the potential of energy savings and to reduce the greenhouse gas emission. The goal of this project is to study the performance of the PVT-assisted GSHP in new- and retrofitted single-family houses.

  • Situation of Opportunity in the Growth and Change of three Stockholm City Districts (completed)

    Situation of Opportunity in the Growth and Change of three Stockholm City Districts – everyday life, built environment and transport explored as Energy Usage Systems (EUS) and Governance Networks

  • Wuxi Sino-Swedish Eco-City Project (completed)

    The project aims at investigating the energy system and innovation process for an upcoming EcoCity in China. With a growth in urbanization, cities are expected to be at the heart of future innovation in energy efficiency. Wuxi Sino-Swedish EcoCity is a unique project, spanning over an area of 2.4 km 2. The project served to showcase different technological solutions in the area of energy efficiency and sustainability that can be used as a hotbed for innovation development and large-scale implementation.

  • Sustainable combined systems for heating of buildings (completed)

  • Cooperation between Supermarkets and Real Estate Owners; Energy Efficiency and Business Models

    The overall aim of the project is to demonstrate, using theoretical calculations, modelling, energy measurements, monitoring and business model evaluation, that a collaboration for efficient use of heating, cooling and air conditioning between real estate and supermarkets owners can be achievable for both parties.

  • Cost- and Energy-Efficient Control Systems for Buildings

    This project exploits high resolution data gathered in KTH Live-in Lab research test-beds through an advanced, modular and flexible monitoring set-up capable to acquire real-time data on indoor environmental quality and the involved energy flows including ground source heat pumps, photovoltaic panels, ventilation. It will provide an assessment of the inefficient energy use of common faulty systems and guidelines for cost-optimal design and for implementation of building monitoring and control systems.

  • PARMENIDES – Plug & plAy EneRgy ManagEmeNt for hybriD Energy Storage

    Hybrid energy storage systems (HESS) are responding to the evolving nature of energy systems and have the potential of enabling greater flexibility in energy communities (EC). Understanding and leveraging EC members’ energy-related behaviors, preferences, and constraints can enhance this potential. The PARMENIDES Project aims to develop an interoperable and secure ontology-based Energy Management System for HESS (EMS4HESS) suited for ECs with energy storage technologies, with a focus on the electricity and heating domain, so they can offer flexibility services to the grid, while finding a balance between stakeholders’ individual and collective objectives.
