01. Monspriger Timber structure | Zero Carbon | DFMA | Group Project | Winter 2022

This proposal looks at the cohesive implementation of 3 strategies i.e. Sustainability, improving academic performance and DFMA. These strategies are implemented with testing various modular timber construction methods with carefully planned functions with aim to give students the space to study in comfort. Full timber super structure, modular construction combined with passive and active low carbon systems, this 5th year project was my first attempt at desinging a net zero carbon building. After calculations, the total carbon from construction (on and off site) and day to day use would be offset within 35 years.

A kit of parts was created to simplify the panalised construction methods used. With this, the amount of time spent for on-site construction could be reduced by better utilising off-site construction where quality of build and waste could be better controlled.

Using a mixture of active and passive strategies, this building was able to reach zero carbon through it’s use of energy generation, low energy consumption and small embodied carbon amount due to timber superstructure.

It should be adressed that high rise timber structure is a controversial topic within the UK however since our building is also aiming to reach UK’s zero carbon by 2030 we wanted to show timber construction can be safe as well as very sustainable.

3 ByLevel implementing energy saving and generating strategies such as grey 13,200 waster recycling, rainwater harvesting, heat recovery systems and PV panels for energy generation we’re able to offset the energy use and reach zero carbon over the building’s life cycle.

A indoor daylight penetration analysis was done through Safira to iterate and test facade performance and massing efficiency. Afterwards, in later stages of design, FCBS carbon tool was used to highlight carbon efficiency through construction and operation. Many materials, tools and methods were considered before deciding on the final Level 2 9,300 construction plan.

02. The Archology Future City | Zero Carbon | Parametric | Individual project | Winter 2023

The project explores and tests the effect of urban density on the satisfaction of residents, businesses and developers through the application of multifunctional typologies, varying density development and policies that ensure house affordability. These theories are tested through a computational simulation model of Eastland Manchester and parametric typologies that adapt to changing parameters.

The computational model adapts and impliments the polciies MCC has planned for Manchester’s Eastland going into the future. By testing the sucess of these policies, the future iteration of the cities show how benifical they will be for economic growth, population growth and enviromental development. The primary aim of this proejct was to find a mixtures of policies applied at key moments in time to ensure a sustainable future where the residents and happy, housing is affordable and investors are satusfied with the profit margin of developement.

With these development rules simplified into a cellular automation model, I could alter them to simulate various policies the Eastland development team from city council wanted to implement. I created projections for housing pricing, business opportunities and changes in overall land value.

Energy considerations for all typologies used in the simulation Grasshopper

With the city council’s push to net zero pledges, each typology was fitted with energy generating tools and changing popularity of typologies resulted in the change in amount of overall energy generated on the site. With this model iterations could be run and tested to find best policies resulting in the lowest carbon future. Lumion

An adaptive resue project of the Righton building currently used by fashion students of MMU. The project client, MMU Estate felt that building has become too derelict to be used at full capacity and the running cost was too much. I approached this building with an broader academic mindset where the functions would would up to more fo the campus than fashion students to reflect teh university’s growth but also to accomodate more functions to ensure none fo the building’s spacil programmes are underutilised.

Facade building- Creating a facade using the building massings

With computation, a surface was wrapped around the massings to create a facade. And then a grid was imposed on top of the facade to create a structural grid for the box sections. this method allows us flexibility as our facade could adapt to our changes in the building massings as we developed the project.

The signal box was a locally driven project on Pendle Lancastershire. A charity organisation called In-situ pendle approached us with redesigning a demolished singal box for them, to apply to the council for permission to rebuild. Many of the local artists, residents and network rail workers were involved in many of the decisions made for this proejct. This project primarily stayed in the early stages with handoff to the client for future development.
