Vapour-open, non-capillary active internally insulated historic solid brick masonry: The influence of hygrothermal properties on the hygrothermal performance

Energy consumption has become a significant global issue due to climatic and environmental challenges, a lack of energy resources, and rising energy prices. The building stock accounts for 40% of the total energy consumption. Therefore, efforts should be made to explore possibilities to reduce energy consumption and related CO2-emissions, not...

Evaluation of High Capacity Hygroscopic Materials on Air Conditions and Energy Performance in Renovated Historic Buildings: A Case Study in the National Holocaust Museum, Amsterdam

Managing climate in museums is always a challenging task since it should meet the needs of multiple stakeholders, namely the conservation of collections, the comfort of visitors, and the protection of historic buildings. The relative humidity is one of the most crucial parameters in this management process, and it is controlled by passive design...

Cochleas: a methodology to convert an existing layout into a residential one

Usually in a renovation design process one of the first main tasks of the architect is to distribute effectively the program of requirements (spaces with their corresponding areas) in the building. To do so the architect inserts in the existing floorplan the spaces in the form of circles; the so called “bubble diagram”. The purpose of this...

Evaluating the potential of mechanically ventilated double-skin façades to enhance energy efficiency and thermal comfort of office buildings in different climate zones of India through numerical modelling

The air-conditioning of commercial buildings accounts for approximately 50% of the total energy consumed in India’s commercial sector. Reducing this load is a key step towards minimizing India's greenhouse gas emissions. One culprit is the routine use of fully glazed façades which are chosen for aesthetics but are neither energy efficient nor...

Computational Design Method Based on Multidisciplinary Design Optimization and Optioneering Techniques for Energy Efficiency and Cost Effectiveness

One of the cutting-edge interests gaining relevance among design offices, notably in the sphere of architecture firms, is computational design. With its inception embedded in the 60s and later reformed through the CAD revolution that boomed in the 80s, the use of the computer as a design tool has evolved to such lengths that it became...

The ENergy Roof

This report describes the development of the ENergy Roof: a new concept for the Nul-op-de-Meter (NoM) renovation of single family dwellings in the Netherlands. The ENergy Roof consists of innovative technology, namely a solar assisted heat pump (SAHP) connected to photovoltaic solar panels that operates as evaporator (PV-DX). Furthermore the...

Passive Offshore Accommodation: An Energy-Efficient Solution for the Façade Refurbishment of an Offshore Accommodation

The purpose of this research is to explore the energy balance within an offshore accommodation. The research is done In cooperation with Keppel Verolme BV. and the TU Delft for the department of Building Technology. The offshore accommodation is analysed in terms of structure and energy consumption, as is the typical environmental conditions in...

Adaptive heat transfer and sunshading for a fully glazed façade

A fully glazed facade is a facade which provides maximal advantages for buildings concerning daylight and view. Daylight reduces the energy use for lighting; view provides comfort and gives the possibility to experience the surroundings of the building. The possibility of providing solar entrance into the building has big influence on the...

Performance assessment of building energy modelling programs and control optimization of thermally activated building systems

In the last decades, there is a lot of discussion about climate change and energy shortage. In building industry great amounts of energy are spent for heating and cooling which in return produce large quantities of CO2 emissions. Therefore, it is self-understandable that efforts towards more effective and sustainable solutions have to be made....

Energy Storage Strategies

This report describes the development of energy storage strategies for short term Thermal Energy Storage in residential buildings with an air-source heat pump. Short term TES allows advanced integration of renewables because the associated mismatch between demand and availability is solved. The aim of the research was to develop control...

The STAR-system: A bio-inspired solution for a thermo regulative façade

This research presents the potentials of the STAR-system: a Solution for a Thermal Adaptive Response system. The STAR-system uses a Phase Change Slurry (PCS) as variable thermal mass to control the indoor temperatures. Nature forms an inspiration for the design of a new system for a thermo regulative façade. Examples from nature are collected...

Koelen door middel van (nacht)ventilatie: Een rekentool voor de architect

Onderzocht is hoe een architect op eenvoudige manier de invloed van koelen door middel van (nacht)ventilatie kan simuleren en daarmee de ontwerp beslissingen kan toetsen of laten beïnvloeden door de uitkomsten van de gemaakte rekentool.

Optimalisatie van zonne-energiegebruik voor woningen met een opslagsystemen

Tegenwoordig zijn de omstandigheden voor de toepassing van zonne-energiesystemen enorm verbeterd. In de toekomst zullen deze omstandigheden waarschijnlijk alleen nog maar beter worden. Het toepassen van zonne-energieopslagsystemen is vooralsnog niet of nauwelijks direct gerelateerd aan de energiebehoefte van huishoudens. De keuze voor een zonne...

Zwembad "De Vosse": Hoe het zwemseizoen te verlengen… …en tóch buiten te kunnen zwemmen?

Zwembad “De Vosse” is een openluchtzwembad in de gemeente Hillegom. Het bad is geopend in de maanden mei, juni, juli en augustus. Bij mooi weer trekt het jaarlijks meer dan 50.000 bezoekers, aangezien het een van de weinige openluchtbaden in de regio is. Voor de exploitatie is het wellicht gunstiger als het bad gedurende een langere periode...
