Minimal renovation strategies for low-temperature heating with optimal comfort

To prepare the housing stock for the transition to collective, low-temperature heating, minimal renovation strategies for the integration of low-temperature heating and optimal comfort are studied within this research for various single-family housing typologies. Renovation measures on the building and installation scale were considered for the...

Simulated thermal comfort in renovated houses with low temperature heating

Low Temperature Heating (LTH) of buildings is a key feature when switching to renewable energy. Even when the capacity of LTH is high enough, LTH may adversely affect indoor thermal comfort in case buildings are not suitably insulated. This paper goes deeper into methodological issues when conducting a thermal comfort assessment. Thermal comfort...

Façade renovations of dwellings for high comfort with low temperature heating

Especially in colder climates, like The Netherlands, a large quantity of non-renewable energy is used for space heating by burning natural gas. To meet climate goals, natural gas should be replaced with renewable sources. Reducing the total energy demand for space heating and lowering the design water temperature in a heating system enable more...

LT-Ready: Affordable renovation concepts that enable low-temperature heating and provided thermal comfort

The Dutch building stock has to switch to alternative energy-efficient heat sources, such as district heating or heat pumps, which will provide a lower supply temperature for the heating system in dwellings. Yet, the consensus is that dwellings need to be intensively renovated, to provide thermal comfort with low-temperature heating. However, it...

Developing a locally balanced energy system for an existing neighbourhood, using the ‘Smart Urban Isle’ approach

This paper describes a step-by-step approach for generating various energy concepts for neighbourhoods, based on local renewable resources. The approach is developed within the European research project ‘Smart Urban Isle’ (SUI). While much literature is focussed on comparison or optimization of predefined configurations, the SUI approach adds...

The prospects for heat: Urban heat modelling as a means for a sustainable and equitable heat transition in the historic centre of Amsterdam

The city of Amsterdam aims to supply buildings in the historic centre of Amsterdam with sustainable, reliable, and affordable heat for space heating. However, currently only hight temperature heat from biomass and waste incinerators can generate sufficient heat to supply this area. This solution does not lead to reducing the carbon emission...

From gas to geothermal energy: Adaptations at building level for a lower temperature in the heating network

The transition from fossil fuels to renewable energy sources brings along the reduction of the supply temperature of the distribution heating networks, because renewable energy sources usually provide heat at lower temperatures. This master thesis specifically focuses on the buildings because it is uncertain which adaptations are necessary to...
